General knowledge of coating: a guide to the selection of emulsion paint for the main materials of home wall decoration

Core tip: latex paint is the main material for interior wall decoration Its components can be divided into three categories: base materials (including water, polymer and various film forming AIDS), pigments and additives (including dispersants, defoamers, preservatives, etc.) There are three processes in the film formation of emulsion paint after construction: one is the accumulation of emulsion particles after water evaporation; the other is the deformation and melting of polymer particles into continuous film when they are continuously dry; the third is the mutual penetration and diffusion of molecules on the surface of polymer, so that the film can be further tested uniformly Therefore, the external environment such as temperature and humidity has a great impact on the construction quality Latex paint Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: latex paint is the main material for interior wall decoration Its components can be divided into three categories: base materials (including water, polymer and various film forming AIDS), pigments and additives (including dispersants, defoamers, preservatives, etc.) There are three processes in the film formation of emulsion paint after construction: one is the accumulation of emulsion particles after water evaporation; the other is the deformation and melting of polymer particles into continuous film when they are continuously dry; the third is the mutual penetration and diffusion of molecules on the surface of polymer, so that the film can be further tested uniformly Therefore, the external environment such as temperature and humidity has a great impact on the construction quality Latex paint is used for interior and exterior walls respectively Because the exterior wall is greatly affected by the external climate, the wind, sun, rain, especially the ultraviolet radiation will make some pigments fade, yellow, powdered and so on Therefore, the weatherability and ultraviolet radiation resistance of exterior wall coating are higher than that of interior wall, and the price is also higher Because the emulsion paint uses water as the dispersion medium, the content of organic matter is low, so it is safe to use In latex paint, only free molecular monomers, such as various acrylate, styrene, vinyl acetate, etc., have different degrees of toxicity, but the content is less than 0.1%, which will not cause harm to human body Therefore, latex paint is basically non-toxic and environmentally friendly The selection of latex paint should consider several aspects: 1 Consider the use location: reception room, hall, bedroom should use high-grade latex paint; balcony can use general latex paint; toilet can use waterproof latex paint Washable latex paint can be used in the kitchen 2 Consider the decoration effect: select the color, glossiness and surface effect of emulsion paint according to the overall design effect of the interior 3 Consideration of funds: the price of emulsion paint varies greatly, with only 5 yuan / kg for low-grade emulsion paint, 10-30 yuan / kg for medium-grade emulsion paint and more than 50 yuan / kg for high-grade emulsion paint There are many domestic manufacturers, and a large number of foreign products have entered China The most famous one is Nippon Paint from Japan Now the products are mainly domestic joint-venture manufacturers Customers can choose according to their needs 4 Beware of buying fake goods The production of latex paint is complex, so there are low-grade and fake products of counterfeit famous brand First, you can't buy latex paint less than 5 yuan / kg, which is mostly fake Second, you can't buy expired products The national regulations stipulate that the storage period of latex paint is 6 months When you buy it, you should pay attention to the date when you leave the factory Third, the impurities are too much to buy Buy latex paint recommended to regular stores Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
