Once the materials are not selected well, it will directly affect the overall decoration effect. In the purchase of decoration materials, Paint is the most influential decoration visual effect, then how to choose the decoration paint suitable for itself?

In daily household decoration, according to the different coatings used, it can be divided into wall paint and wood paint. At present, most of the well-known paint brands in China focus on the wall paint, but also on the wall paint. The beautiful doors and lacquers in seaweed mud and children's lacquer wood lacquer are popular products.

According to different diluents, paints can be divided into water-based paints and oil-based paints. Latex paints are mainly water-based paints, while nitrocellulose paints, polyester greases, etc. are mostly oil-based paints. Wall paints are made of water-based latex paint and wood. And the brushing of metal furniture is oily paint. The most used in home decoration is wall paint and wood lacquer. If you can understand it, you can avoid being deceived and suffer unnecessary losses.

Wood lacquers include nitrocellulose lacquer, polyester lacquer and more environmentally friendly waterborne wood lacquer.

Polyester lacquer is a thick lacquer made of polyester resin as the main film-forming material. Its paint film is full of thick layer and hard varnish. The amount of curing curing agent needed during the construction of polyester lacquer is about the total amount of paint. One third of the amount is TDI (toluene diisocyanate / toluenediisocyanate). The TDI in the free state will not only yellow the furniture paint but also the adjacent wall. This is a polyester paint. A major shortcoming. At present, there is a yellowing-resistant polyester paint on the market, but it can only cure the symptoms and can not cure the yellowing.

In addition, the free TDI beyond the standard will cause harm to the human body. Long-term inhalation will cause painful tears, conjunctival congestion, cough and chest tightness, shortness of breath, red papules, maculopapular rash, contact allergic dermatitis and other symptoms. The limit of TDI is to carefully read the instructions when purchasing below 0.5%.

Nitro varnish: also known as clear paint, which has the characteristics of fast drying, hard, bright, wear-resistant and durable. It is a high-grade coating suitable for the coating of wood and metal surfaces. It can also be used for high-grade doors and windows, siding and handrails. The main blending aids are Tianna water and white water. These substances contain esters, alcohols, benzenes, ketones and other organic solvent mixtures. They mainly blend nitrocellulose lacquer and cure and eliminate the whitening phenomenon of the paint surface. However, it is volatile. Harmful substances are very harmful to the human body. After renovation, it is necessary to ventilate to avoid remaining in the indoor air.

Water-based paint: water-soluble resin as film-forming material with water as solvent. Suitable for wooden furniture doors and windows, wall and ceiling. High-grade latex paint products should be healthy and environmentally friendly products. Water-based paint does not contain benzene, toluene, xylene Formaldehyde, free TDI toxic heavy metals non-toxic and non-irritating odor is harmless to the human body, does not pollute the environment, and is resistant to yellowing, fast drying and easy to use. Water-based paint is still in the initial stage of development in China but the market has a good response. Carpoly is a domestic water-based paint. Leading brand has the largest water-based paint production base in Asia.

Interior wall wall paint: generally based on latex paint, emulsion paint can be divided into two categories: polyvinyl acetate emulsion and acrylic emulsion according to different substrates. Latex paint with water as thinner is a convenient and safe construction. The water-resistant and breathable paint products can also be made into different colors according to different needs. The latex paints are made of water, pigments, emulsions, fillers and various additives, but there are still unscrupulous manufacturers in the market. Paint lacquer fake latex paint.

Understanding the basics of coatings is only the first step to avoid buying fake and shoddy paints.

Paint paint is the last ring of decoration and the most intuitive reflection of the decoration effect of the room. The low-grade inferior paint gloss is uneven, easy to yellow, brittle, cracked and peeled off, not only wastes high-quality plates but also pollutes the indoor environment and destroys the overall decoration effect. High-quality paint Not only can it make up for the defects of the previous decoration, but also improve the grade and grade of the decoration. However, there is no obvious difference in the appearance of the paint. How to choose it? Here are some of the easiest ways to choose.

1. Look at the brand strength. Brand awareness, high reputation, good product quality, stable quality, large enterprises are guaranteed. For example, Carpoly is the largest private coating brand in China. The quality and service of the products are well-known in the industry.

2, look at the weight of the product. Lift the paint bucket and shake it. If there is a squeaky voice, the package is seriously insufficient. The viscosity is too low and the real product can hardly hear the sound.

3, look at the supporting materials of the product. Good product professionalism is not only has strict process requirements, but also according to the texture, color, structure or object of the design of different model styles and color cards and provide technical guidance and after-sales service.

4, look at the packaging of the product. Whether the outer packaging logo is complete, the main components of the product, environmental specifications, certificate of conformity, whether the manufacturer produces a clear statement.

Paint coating is one of the important sources of pollution. The emergence of green paint is undoubtedly a guarantee of health. The so-called green paint is a non-toxic, odor-free coating that can protect the environment and inhibit the growth of mold.

How to identify green paint when purchasing paint?

First of all, to buy green paint, you should choose a well-known brand to go to a regular store to see if the product meets the relevant national environmental standards.

Secondly, we should carefully read the quality inspection report of the product, especially the VOC content on the quality inspection report. The national standard stipulates that the VOC content is not more than 200g per liter. The preferred coating is less than 0g per liter of environmentally friendly paint.

If you can get the dealer's consent, you can let it open the paint bucket and check it yourself. If there is serious stratification, the quality is poor. After gently lifting with a stick, the paint stays on the stick for a long time and the coverage is uniform. Better; the lighter the hand, the finer the better.

In addition, unqualified coatings are harmful to toxic odors due to excessive levels of harmful substances such as VOC and formaldehyde. Therefore, it is necessary to carefully select brand coatings with quality assurance and technical services.
