Paint is indispensable in our home improvement materials, and the quality of the paint directly affects the quality of indoor air. Therefore, when choosing a paint, it must not be cheap, but there are many precautions in choosing a paint, so how do we choose environmental protection? What about paint?
1. Liquid solvent-free coating. At present, there are two types of coatings that do not contain organic solvents, such as two-liquid type and potable type.
2. High solid content solvent coating. In order to meet the increasingly demanding environmental protection requirements, under the premise of using the original common solvent-based paint production process, the amount of organic solvent is reduced and the solid content is improved. The solid content of the low solids solvent-based coatings is 30%-50% solids; the high solids solid solvent-containing coatings require solids content of 65%-85%, which greatly reduces the release of volatile organic compounds.
3. Dust paint. The release of volatile organic compounds in domestically advanced coatings is one of the main directions for the development of coatings. However, due to its relatively complicated manufacturing process and high cost, the baking temperature is much higher than that of the general coating, it is difficult to obtain a thin coating, the color matching property of the coating is poor, and the uniform coating property of the irregular moon object is also limited. usage of. Therefore, further improvements are required.
4, water tomb paint. The water has the characteristics of non-toxic and non-existent, and the introduction of water into the coating not only reduces the cost of the coating, but also avoids the fire caused by the improper use of the organic Luojing, and also greatly reduces the release of volatile organic compounds. Therefore, the water tomb paint has been rapidly developed.
