Lacquer (lacquer) has a very long history. Archaeologists discovered a lacquered wooden bowl (sound xiu, refers to lacquered utensils) at the Hemudu site, which has been around for more than 7,000 years.

One: the origin of "lacquer"

Seal writing of lacquer characters

Lacquer (lacquer) has a very long history. Archaeologists discovered a lacquered wooden bowl (sound xiu, refers to lacquered utensils) at the Hemudu site, which has been around for more than 7,000 years. According to historical data, in the Neolithic period, the ancients had already realized the performance of lacquer and used it to make utensils. The composition of the word "lacquer" can also be proved: lacquer is derived from sumach (lacque tree), and the Chinese characters of all tree names are from the side of the wood, such as: pine, cypress, beech, poplar, etc., only the word "lacquer" follows from water.

Because sap will flow out of the trunk of this tree, it is called "桼": the upper part is from the wood, the middle from the person, and the lower part from the water, which vividly shows the relationship between the sumac tree, the person, and the lacquer. There is a saying in "Zhuangzi·Renshijian": "lacquer can be used, so cut it" is the earliest record of harvesting raw lacquer in China.

Two: Big Lacquer and Lacquer

Large lacquer (Chinese lacquer; Japan; Japanlac), also known as natural lacquer, raw lacquer, soil lacquer, national lacquer. People in the past did not know the chemical principles used to make lacquer, but mastered the mystery of lacquer through constant observation and practice. The lacquer liquid naturally secreted from the sumac tree will form a black shiny lacquer film after sun exposure, which attracted the attention of the ancients and wondered how to use it. Slowly, people learned to collect more lacquer from the lacquer tree, brush it on the utensils, and become the original lacquerware.

The artificial cultivation of the sumac tree came into being. The "Book of Songs" records: "The Dingzhi Fang was made in the Chu Palace, the Kuzhi was made in the Chu room, and the tree was hazel, chestnut, tong, catalpa, and lacquer", indicating that it was in the pre-Qin period , Sumac has become an economic tree species.

Characteristics of sumac

Sumac is a deciduous tree with a height of up to 20 meters. The leaves are oval, yellow-green flowers bloom in early summer, and they become oblate in autumn. Lacquer trees are widely distributed in China, and the provinces surrounding the Sichuan Basin are its distribution centers. Because these areas have a mild climate, they are very suitable for the growth of lacquer trees.

This is a small wood lacquer planted by hand. Cutting the lacquer requires climbing trees.

Lacquer trees more than eight years old can produce lacquer. Lacquer farms use clam shells to cut the bark, insert the clam shells or bamboo slices under the knife edge, and collect the lacquer solution into the wooden barrel and seal it with oil paper for storage. The natural lacquer cut from the sumac tree is called raw lacquer, and the cooked lacquer refers to the raw lacquer that has been oxidized with tung oil after being exposed to sunlight and stirring.

After about two hours, the paint has changed from milky white to chestnut shell color.

The main component of lacquer is urushiol. Others include gum, nitrogen, moisture and trace volatile acid. The freshly cut lacquer is milky white and viscous. After contact with air, the oxidized color will gradually darken, and finally become Chestnut shell. Raw lacquer is difficult to be mixed into bright color paint, because raw lacquer itself is deep in color, and when the pigment is added to it, it is easy to be conquered by the original color of raw lacquer, so the ancient lacquer is mostly black and vermilion.

Collect the paint in the jar little by little

"The Zhumen's wine and meat are smelly and there are frozen bones on the road." The Zhu lacquer gate in Du Fu's poem was used exclusively by the government during the feudal period, and ordinary people mostly chose black lacquer in order to avoid suspicion. As the saying goes, "Anyone who says nothing is dark", and now people still use "pitch black" to describe the darkness of the night. As for making the raw lacquer black, you can mix the iron rust water into the lacquer, and the iron oxide and urushiol will react in color. After mixing it evenly, brush it on the object, as dark as ink. This black lacquer is also called black lacquer and black lacquer.

Large lacquer furniture in the Ming and Qing dynasties

Although lacquer is a natural plant lacquer, some people will have skin allergies when they come into contact with wet lacquer, and even get a rash when they smell the lacquer. In such a situation, the masters would say that they were "bitten" by the lacquer. In fact, this is a lacquer allergy. Generally speaking, no special treatment is needed, and it will heal on its own in about seven days.

Exquisite Japanese Lacquerware

The application of large lacquer has a long history and is well-known at home and abroad. It has little impact on the environment. It has the functions of waterproof, insect-proof, sterilization and anti-corrosion. The paint has strong endurance to acidity, salt and humidity. Its function can not only beautify, but also protect the utensils. It has always been regarded as the first choice of ideal paint. Therefore, the paint industry is very prosperous and enduring. Lacquerware and porcelain were regarded as symbols of Eastern civilization and then spread to Japan. Because Japanese people rely on lacquerware in their lives far beyond other ethnic groups, Westerners call lacquerware "Japan" and porcelain "China". ".

The practice of treating chopsticks with lacquer is still very popular

Daqi faced the real challenge in the 20th century. Due to the limitations of single-variety, low labor productivity, low mass production, and high cost of lacquer, with the emergence of modern chemical coatings, the scope of application of lacquer has become narrower and narrower. Due to the cheap raw materials, easy mass production, low cost, multiple functions, and wide application of chemical coatings, it has almost replaced this traditional coating that has been used for thousands of years.

Three: Tung Oil

Tung Tree and Tung Blossom

Because of the limited output of lacquer, the ancients found tung oil. Tung oil was easier to obtain and lower cost than lacquer. Therefore, the ancients often mixed tung oil in the lacquer and mixed the oil with the lacquer to make the best use of the strengths. , Can be described as a pioneering work, this is how the term paint came into being.

Tung tree seeds used to squeeze oil

Tung oil is an industrial vegetable oil made by mechanically squeezing the picked tung tree seeds and processing and refining it. The oil content of Tung oil seeds is generally above 35%, of which the kernel oil content is about 60%. Raw tung oil is also called embryo oil. It has a light yellow appearance, slow drying speed, and poor transparency and viscosity of the paint film, so it cannot be directly used for painting. Raw tung oil is boiled at high temperature, and rosin is added as a desiccant. After precision filtration, it becomes cooked tung oil. The stability and coating effect are greatly improved. The oil film has obvious texture, which has a certain degree of hardness and good performance. Extensibility and elasticity, but the anti-aging performance is not as good as that of large lacquer.

The color difference between cooked tung oil and raw tung oil is obvious

The cooking process of cooked tung oil is more complicated and highly sensitive to oil temperature. There is no uniform quality standard for tung oil products on the market and can be used for painting, but the expected effect cannot be guaranteed. The oil film of some poor-quality cooked tung oil will appear frost, netting, and silk patterns. Tung oil has a wide range of uses. It is the main raw material for the manufacture of paints and inks. It can also be used to make tarpaulins, oiled paper, soap, pesticides, medical vomiting agents, insecticides, etc. Historically, the most common use of tung oil was the anti-corrosion of ancient wooden buildings. It was not only low-cost, but also effective.

Ancient Chinese wooden buildings using tung oil as antiseptic

The oleic acid contained in tung oil is irritating to mucous membranes and will damage the liver and kidneys after absorption. The volatile oleic acid smell of raw tung oil is much greater than that of cooked tung oil. It should be noted that the appearance of tung oil is similar to that of edible oil, but it cannot be eaten. If ingested, it will cause severe vomiting. If a small amount of tung oil is mixed with edible oil, it is even more dangerous. Long-term consumption may cause subacute poisoning.

The surface of the traditional oiled paper umbrella is coated with tung oil

Four: beeswax

Traditional furniture in our country is coated with "southern lacquer and north wax". That is to say, the weather in the south is humid, in order to protect the wood, it is popular to use lacquer for painting, while the climate in the north is dry, and the furniture is mostly treated with beeswax. But the "southern lacquer and north wax" is not absolute. The practice of lacquering and waxing can be seen in the north and south, and the purpose is to prevent the humidity and temperature changes in the atmosphere from affecting the wood.

The source of beeswax is honeycomb

Beeswax, also known as yellow wax, was called "huangzhan" and "beeswax" in ancient times. It is secreted by worker bees responsible for nurturing young bees and is the raw material for constructing honeycombs. The main component of beeswax is ester. The newly secreted beeswax is white and transparent, that is, the wax scale. After being chewed by worker bees, it becomes opaque. After being built into a honeycomb, it becomes familiar with the mixture of propolis and pollen oil for a long time. Yellow. Worker bees need to consume 8 parts of honey to secrete 1 part of beeswax from the wax glands in the abdomen. According to statistics, to produce 1kg of beeswax, a bee needs to fly 530,000 kilometers. The world produces only 10,000 tons of beeswax every year.

Different forms of beeswax products

The price of pure beeswax is relatively high (approximately 4 times the price of honey), so mixed waxes are mostly used for furniture coating, and paraffin wax, rosin and other substances are added to beeswax. Paraffin wax is a very controversial substance with a wide range of uses (such as wax paper, crayons, candles, carbon paper). Paraffin wax is generally extracted directly from petroleum. Under normal circumstances, paraffin wax is considered non-toxic, but it is often Doped with some heavy metal residues.

Paraffin wax products of petroleum extract

Because beeswax is an inert substance, it is incompatible with the resin and moisture of the wood itself. It can form a protective layer on the surface of the wood to isolate water and increase the luster of the surface, extending the service life; at the same time, the wax will not completely seal the wood. The original pores will not affect the natural fragrance emission and the breathing effect of heat expansion and cold contraction. Waxing generally uses a hot wax process, so that the liquid wax can be immersed in the wood fiber.

Paraffin wax is also the main raw material for candles

After waxed furniture is used for a period of time, the surface will be "padding", which can better protect and moisturize the wood. Although beeswax cannot conceal the color difference of the wood itself, the protection effect is not as good as the complete isolation of lacquer, but it is a way to maintain the beauty of the wood itself. The two limiting factors of beeswax are: First, it is expensive. two. The waxing process is complicated and not suitable for modern production operations.

Floor hot wax

Five: walnut oil

Furniture wiped with walnut oil is very shiny, and this usage is also very popular among folks, but it is fundamentally not suitable as a coating material for wood.

Walnuts are rich in nutrients.

Although both walnut oil and tung oil are vegetable oils, the difference is that walnut oil is a kind of active oil. The content of unsaturated fatty acid exceeds 80%. After it penetrates into the wood, it will decompose the wood fiber and reduce the strength of the wood, thus affecting the service life of the furniture. Walnut oil is the right way to be used as edible oil. Because of the high content of unsaturated fatty acids, it has a positive effect on softening blood vessels, lowering the body's cholesterol content, and preventing arteriosclerosis and thrombosis. In addition, compared with beeswax, furniture wiped with walnut oil is easier to absorb dust, and because it is rich in nutrients, it is also easy to become a breeding ground for mites and bacteria.

Six: Coatings and paints

The term "paint" comes from the golden combination of tung oil + lacquer, but now the term "coatings" is more widely used. It is one of the achievements of polymer theory and science in the 20th century. In the 1930s, the chemical industry invented alkyd. Although it is a synthetic resin, it has not yet left the raw material of vegetable oil. It is safe to call it synthetic resin paint. Later, a lot of epoxy resins appeared. Purely synthetic things, then called paint, always feel that something is not right. So we started to use the term paint.

Modern chemical coating products are very versatile

The rapid development of the modern coatings industry has directly led to confusion in the usage of the two names paint and paint. According to the current standard definition, paint refers to a general term for a type of liquid or solid material that is coated on the surface of an object to form a solid coating film with protective, decorative or special properties (such as insulation, anti-corrosion, etc.). Coating products are so dazzling that how to classify them has become a new problem.

A typical chemical plant, the source of raw materials for coating products.

Obviously, the name paint can no longer cover the various existing products in the industry, such as powder coatings. Even in the category of liquid coatings, water-based paints and oil-based paints should also be classified separately, because the chemical properties of the two are quite different. The paint in the standard sense needs to form a coating film to play a protective role, while wood wax oil is a fully open coating without paint film. Its principle of action is fundamentally different from other products. If wood wax oil is included in the paint In the first category, it seems necessary to modify the definition of paint.

Seven: Water-based paint and oil-based paint

It is a thankless task to introduce modern chemical coatings in detail, because the chemistry involved can make the article very boring. However, for environmental protection and health, it is still necessary to spend some energy to understand the difference between water-based paint and oil-based paint.

Latex paint is one of the most commonly used water-based paint varieties

Water-based paint and oil-based paint should be more scientifically called water-based paint and solvent-based paint. Coatings generally consist of four parts: film-forming substances, pigments, solvents and additives. The dispersing medium is also called a solvent. Its function is to dissolve or disperse the film-forming substance in the coating into a uniform liquid state to facilitate the construction of the film. The dispersing medium will volatilize into the air after construction.

The difference between water-based coatings and solvent-based coatings lies in the different dispersion media. Paints that use water as a dispersion medium are called water-based paints. Water-based coatings use water-soluble resin as the film-forming material, represented by polyvinyl alcohol and various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins and inorganic polymer water-based resins Wait. The paint that uses organic solvent as the dispersion medium is called solvent-based paint (oil-based paint/paint). Organic solvents are mainly hydrocarbons, and the rest are ketones, alcohols, glycols, ethers, esters, nitro branched chain alkanes, etc. These highly volatile organic compounds are the main cause of paint harm to the environment and health. The full name of our commonly used VOC data is Volatile Organic Compounds, which refers to the content of volatile organic compounds. VOC harms the human body in varying degrees. Mild symptoms may include: respiratory tract irritation, eye irritation, headache, dizziness, skin allergies, tiredness, etc., severely may cause liver and kidney damage or cause cancer. In addition, VOC is also the main cause of photochemical smog.

At the early stage of the development of the modern chemical industry, almost all coatings were solvent-based coatings. Later, water-based coatings, powder coatings, light-curing coatings, etc. appeared. The main driving force was to reduce VOC emissions. The United States first formulated the famous 66 regulations that restrict the use of solvents (which stipulates that the solvent content in coatings should not exceed 17%) and CAA (Clean Air Act) regulations, requiring coatings to transition to water-based systems. my country issued a "Medium and Long-term Development Plan for the Coating Industry Technology" in 2008. It plans to significantly reduce the proportion of traditional solvent coatings in the next 10 years, reducing its share from the current 50% to 5%. It will take 10-15 years to implement new technological transformations in the traditional coating industry, and ultimately reduce the market share of traditional solvent coatings to less than 1%.

Oil-based paint is very harmful to the environment and health

Desires are beautiful, reality is cruel, and it is not easy to achieve the planned goals. Water-based paint uses water as the dispersion medium, which can save a lot of resources compared with solvent-based paints, eliminates the risk of fire during construction, and greatly reduces the degree of pollution. At the same time, the water-based paint contains only a small amount of low-toxic alcohol ether organic solvents, which improves The working environment of construction personnel is conducive to health. Water-based coatings have many benefits, but solvent-based coatings still dominate in some aspects. From the performance of the paint film, the corrosion resistance, weather resistance and fullness of water-based coatings are not as good as solvent-based coatings. Water-based coatings have more stringent requirements on the temperature and humidity of the construction environment, and the application occasions are therefore limited.

China's environmental label

Environmental labels of other countries

The paint market in my country is very irregular. If consumers want to choose paint products, they should not be superstitious about environmental protection signs, because surveys show that most of the environmental protection signs are imitation or homemade. In this case, the easiest way is to use high-quality brand water-based coating products, which is a relatively safer choice.

The world's first two-component water-based paint launched by Japan's Asahi Company

The technology of water-based coatings is relatively new. It was not until 2008 that Asahi Paint Co., Ltd. launched the world's first real two-component water-based paint. Its film performance can catch up with oil-based paints in terms of hardness and weather resistance. The launch of this product is of great significance and has changed the usual impression of insufficient performance of water-based paints. But so far, only a few paint manufacturers have mastered the two-component water-based paint technology, and because of its high price, it has restricted its popularity.

Petroleum resin products are the basic raw materials of modern coating products

The composition of the coating was mentioned earlier, and the film-forming substances need to be added. The film-forming substance is the basis of the coating, and it has the function of binding other components in the coating to form a coating film. Film-forming substances are mainly various resins. In the past, natural resins were used as film-forming substances in coatings, such as urushiol and tung oil in lacquer. Now synthetic resins are widely used, such as alkyd resins, acrylic resins, and chlorinated resins. Rubber resin, epoxy resin, etc. According to national standards, coatings should be classified and named according to film-forming substances. Therefore, we often hear the names of nitrocellulose, polyester paint, acrylic paint, etc., which are obviously too abstract for ordinary consumers who lack professional knowledge.

Eight: Wood paint

Wood paint refers to all paints used on wood products. We recommend that it be divided into three categories: water-based paint, oil-based paint and wood wax oil. The working principle of wood wax oil is very different from the previous two types, so it will be introduced separately later.

One: Water-based wood paint

Part of S03 shelf painted with water-based paint

A. The primary product of water-based wood paint uses acrylic acid as the film-forming material, which has poor abrasion resistance and chemical resistance and average gloss, but the cost is low and the technical content is not high.

B. Intermediate products are mainly composed of a composite of acrylic acid and polyurethane, which have enhanced abrasion resistance and chemical resistance, with moderate cost and relatively high acceptance.

C. Polyurethane water-based wood paint, abrasion resistance may exceed ordinary oil paint, but the price is more expensive, it is a high-end product.

Water-based wood paint has much lower VOC content than oil-based paint, which not only has a small impact on the environment, but is also good for the health of constructors and users. However, the wood coatings market is still dominated by oil-based paints. Some analysts believe that three factors restrict the development of water-based paint: one is performance, the other is construction conditions, and the third is price. The development of the contemporary coating industry follows the "4E" principle, namely Economy, Ecology, Eenergy, and Efficiency. However, in the field of wood coatings, the share of water-based paints is still very limited.

Among the reasons for the EU recall of Chinese toys in 2009, the paint problem ranked first

It is a well-known fact that the Chinese government has long implemented low standards in the field of product safety. It was not until after joining the WTO that a large number of foreign trade disputes caused by quality issues forced the government to make certain improvements, which is also one of the important reasons why water-based paint cannot be widely used. In 2007, Mattel, the world’s largest toy company, announced the recall of 967,000 OEM toys produced by Lida in Foshan, China. The reason was that the lead content in the toy paint was too high. Lida was in a predicament and China’s toys are safe. The problem has once again become the focus of global attention.

The proportion of water-based paint for children's toys is relatively high

Toys are products that are in direct contact with the human body, especially children, so the quality standards of toy coatings should be the highest. However, my country's first "Limit of Hazardous Substances in Toy Coatings" was not officially implemented until 2010, which stipulated that the lead content in toy coatings was ≤600mg/kg (the American standard is 90mg/kg) and volatile organic compounds (VOC) ≤720g/L, benzene content ≤0.3%, toluene, ethylbenzene, xylene ≤0.3%, and 8 soluble elements, six types of phthalate limit requirements, which makes the proportion of water-based paint in toy products has seen an increase.

2: Oily wood paint

A, Daqi, see the second paragraph of this article.

B, varnish (varnish), also known as Van Lishui, varnish used to be the most common type of paint in home decoration, because it has low requirements for construction and can be operated without professionals. The leveling of the varnish is very good, and it doesn't matter if the lacquer tears appear, brush it again, the lacquer tears can be dissolved again. Varnish has the characteristics of transparency, fast film formation, and water resistance. The disadvantages are that the hardness of the coating film is not high, the heat resistance is poor, and it is easy to turn yellow under the action of ultraviolet light.

Panel furniture painted with nitrocellulose lacquer

C, nitrocellulose paint (NC paint) is a relatively common paint for woodware and decoration. The main film-forming material of nitrocellulose lacquer is mainly nitrocellulose, combined with alkyd resin, modified rosin resin, acrylic resin, amino resin and other soft and hard resins. Generally, it is necessary to add plasticizers such as dibutyl phthalate, dioctyl ester, and oxidized castor oil. Solvents mainly include true solvents such as esters, ketones and alcohol ethers, co-solvents such as alcohols, and diluents such as benzene. The characteristics of nitrocellulose lacquer are fast drying speed, bright and smooth coating film, and good workability and repairability. However, the heat resistance and chemical resistance of the nitro paint film is not as good as that of polyurethane paint (PU paint), and it is easy to whiten when it is applied in high humidity weather.

PU paint is the most widely used paint, with good film performance, but not environmentally friendly

D. Polyurethane paint (PU paint), or polyurethane paint, is the most widely used paint in my country's furniture industry. Its comprehensive performance is relatively excellent, but because it is not environmentally friendly, it has basically been eliminated in Europe. It has strong paint film, full luster, strong adhesion, water resistance, abrasion resistance, and corrosion resistance. It is widely used in high-grade wood furniture and can also be used on metal surfaces. Its shortcomings mainly include problems such as damp foaming and chalking of the paint film. Like polyester paint, it also has the problem of yellowing.

E. Polyester paint (PE paint) is a thick paint made of polyester resin as the main film-forming material. The paint film of polyester paint is plump, with thick layers and hard surfaces. The polyester paint needs to be cured during the construction process, and the amount of these curing agents accounts for one third of the total amount of the paint. These curing agents are also called hardeners, and their main component is TDI (toluene diisocyanate). These free TDIs will turn yellow, which will not only turn the paint surface of the furniture yellow, but also turn the adjacent walls yellow, which is a major disadvantage of polyester paint.

F, Ultraviolet Curing Paint (UV, Ultraviolet Curing Paint), UV paint is named after the curing method of the paint. It is automatically roll coated and shower coated on the furniture board through machinery and equipment. Under ultraviolet light (wavelength is 320 -390nm) irradiation promotes the decomposition of the initiator, generates free radicals, initiates the resin reaction, and instantaneously cures to form a film. UV paint is one of the most environmentally friendly varieties of oil-based paints. In foreign countries, especially in Europe, almost every large-scale furniture manufacturer has at least one complete furniture UV paint coating production line. At this time, the products are from sanding , Filling, sealing, and coloring of the bottom coating and drying, all one-time uninterrupted coating is completed.

Nine: Latex paint

In the decoration, as long as it is related to wall problems, most of them cannot do without latex paint. Emulsion Paint is a kind of water-based paint. It is mainly composed of five components: one is water; the other is emulsion, which is similar to white glue, which acts as an adhesion agent and is the core component of latex paint. ; The third is the pigment; the fourth is the filler; the fifth is the additive, such as anti-foaming agent, antifreeze and so on.

Most of the wall coatings used in rural areas are primary products with average weather resistance.

Latex paint was produced in the middle and late 1970s. Before that, people generally used lime water and a kind of wall paint called "big white". The Corsa silver that emerged in the 1960s, and the commonly used in the 1970s and 1980s Glue 107 and Glue 106, these are the water-based coatings used in the early days. The common disadvantages of these primary coatings are easy peeling, chalking, rough and dull surface, and they do not have basic wall protection such as waterproof and stain resistance. Performance, not to mention color, environmental protection and other requirements.

Latex paint products have become the mainstream of home wall coatings

Latex paint has many advantages that are different from traditional wall coatings, such as easy painting, rapid drying, good water resistance and scrubbing resistance of the paint film. The main components of latex paint are non-toxic resin and water, without lead and mercury. During the painting process, no irritating odor will be produced, no harm to humans, organisms and the surrounding environment will be caused, and there will be no explosion and fire hazards in transportation and storage. The most important environmental index of latex paint is the content of volatile organic compounds (VOC). National standards stipulate that the VOC content in each liter of latex paint cannot exceed 200 grams, and most brands can meet this standard.

Ten: Wood wax oil

The main ingredients of wood wax oil are natural plant materials

The main components of wood wax oil are linseed oil, thistle oil, sunflower oil, soybean oil and carnauba wax. The principle of action is equivalent to the improvement of the traditional combination of tung oil + beeswax. The oil component can penetrate into the wood to moisturize and maintain the wood, reflecting the natural texture and texture of the wood; the wax component is firmly combined with the wood fiber, preventing liquid water from penetrating into the wood, and increasing the hardness and hardness of the wood surface. Smoothness. The main composition of wood wax oil is vegetable oil, and the coloring uses iron oxide and other pigments to eliminate toxic and harmful volatiles such as benzene and formaldehyde from the raw materials. Therefore, its environmental protection performance exceeds that of water-based paint, and whether it is manufactured or used From a different point of view, wood wax oil consumes less environmental resources and is more beneficial to ecology and health.

The protection principle of wood wax oil is different from that of paint

It is a pioneering work in the coating industry that wood wax oil is no longer used to protect wood products through a fully enclosed paint film. Wood treated with wood wax oil not only has a unique natural texture, but also provides a skin-like touch. The usual paint will form a plastic-like film on the surface of the wood, making it easy to touch no matter what kind of wood. It is a cold polymer material.

The effect of treating wooden floor with wood wax oil

The wood products treated with wood wax oil are closer to people, and the construction operation is very simple. Just wipe 1-2 times with a brush or a clean cotton cloth. After drying, use a scouring pad to polish it. There is no technical difficulty for anyone, and it is very suitable for DIY, which will make the maintenance and maintenance of furniture a healthy and happy thing.

Advantages of wood wax oil

Judging the effect of paint will emphasize the hardness and wear resistance of the paint film, but the anti-wear principle of wood wax oil is different from it, which can be described as rigid and flexible. Although the paint film of the polyurethane paint is hard, it looks smooth and shiny, it is easy to leave scratches during use, and it is difficult to repair. After ten years, it may not bear witnessing. At this time, the only way is to ask professionals to wear off the paint film and renew it. Painted. The wood wax oil penetrates into the surface of the wood, and the opposite is done, using the flexibility of the wood itself to resist abrasion, there will be no obvious scratches, it is very easy to repair, you can do it yourself, so there is no problem in using it for decades. Different people have different opinions on which one is better.

Carnauba wax is the most widely used natural plant wax extracted from palm leaves that grow in northeastern Brazil.

The main purpose of using wood wax oil is for health, environmental protection and natural texture, but its application is still limited. The protection principle of wood wax oil determines that it is only suitable for solid wood. For wood board, density board, plywood, etc., which are widely used in the market, wood wax oil cannot exert its effect. Even for solid wood, wood wax oil has different effects on different types of wood.

Wood wax oil penetrates into the wood, which will deepen the color difference of the wood itself

Special attention should be paid to the fact that wood wax oil cannot hide the ugliness, and even deepens the color difference of the wood itself. This may be the main reason why most furniture brands are reluctant to use wood wax oil. But in our opinion, this shortcoming is also its advantage. Wood is a natural material. Of course, what is presented to people is not only a perfect texture, but also tree knots, tree tumors and even insects. If we look at it with awe and make good use of it, it will not only beautify life, It will also help us map out the path to understanding life forms.

Conclusion:

The road to the ideal paint is tortuous and long. The lacquer that has been used for thousands of years has always been regarded as the representative of the ideal paint. However, the development and progress of the chemical industry in the past century and the diversification of social needs have led to the gradual disappearance of lacquer from people's vision. While modern coating products are widely used, humans are paying more and more attention to environmental protection and health issues, which promotes the transition of solvent-based coatings to water-based systems. In the 1980s, wood wax oil appeared in Europe and quickly became popular. It satisfies people's inherent needs in pursuit of nature and truly returns to the tradition of early plant coatings.
