    Core tip: the first process of coating material production is deployment, which determines whether the coating is bright and complete, and whether the construction is simple and easy To improve these performance, you must follow these five deployment rules: The first rule: the adjustment of burnishing The sanding adjustment of waterborne wood paint is very important for the whole construction Just like transparent putty and transparent primer, good burnishing is necessary Generally speaking, the higher the hardness of water-based wood paint, the better the burnability; the longer the drying time, the better the burnability Simultaneous adoption 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 Coating home news: the first process of coating material production is deployment, which determines whether the coating is bright and complete, and whether the construction is simple and easy In order to improve these properties, we must follow the following five deployment rules: the first rule: sanding adjustment The sanding adjustment of waterborne wood paint is very important for the whole construction Just like transparent putty and transparent primer, good burnishing is necessary Generally speaking, the higher the hardness of water-based wood paint, the better the burnability; the longer the drying time, the better the burnability At the same time, by adjusting the formula or using some well dispersed slurry, it can improve the grindability The second rule: the adjustment of drying speed Drying speed is a key factor in the construction of waterborne wood paint factory Because the operation of the factory should be more compact and it can't wait so long after painting, the drying speed of the paint can directly affect the production efficiency of the factory In order to replace oily Wood paint, the drying speed must be improved There are two kinds of film-forming additives in its formulation: one is ethylene glycol butyl ether and dipropylene glycol butyl ether, the other is propylene glycol butyl ether and dipropylene glycol methyl ether By properly adjusting the proportion of the two film forming AIDS, the drying speed and the total amount of film forming aids can be adjusted The third rule: the balance between leveling and sagging The final step in the production of waterborne wood paint is viscosity adjustment, which is called rheological property Good water-based wood paint should have good leveling property as well as good anti sagging property On the other hand, the touch and luster of the film will be greatly improved However, if the viscosity is not enough, it will cause sagging If the viscosity is too high, it will affect the leveling Therefore, in order to maintain the balance between leveling and sagging, polyurethane thickener is generally used, which will not affect the water resistance, but also improve the viscosity and leveling Fourth rule: surface modification Because many buyers like to use their fingernails or keys to scratch the paint film when judging whether the paint is good or bad? So water-based wood paint must have high hardness and scratch resistance It's a little difficult to achieve the hardness of 2-3H for one component waterborne wood paint, and it also needs to have good scratch resistance In general, some surface additives can be added to the waterborne wood paint to make it move to the surface gradually during the drying process of the paint film The scratch resistance of the paint film can be improved by using its own characteristics and higher hardness Fifth rule: improve transparency The higher the transparency is, the more natural the wood texture will be displayed Silica extinction powder determines the balance between transparency and gloss adjustment In a word, in order to achieve a good coating effect of waterborne wood paint, we must grasp the above five formula adjustment methods 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,
