替换城市 Principle and influencing factors of special paint defoamer agents for paints(1)



替换城市  Principle of special paint defoamer for paints:




Powder is defined as a substance that can reduce the aggregation of solid or liquid particles in a dispersion system. When adding dispersants and suspensions to the preparation of emulsifiable concentrates and wettable powders, it is easy to form dispersants and suspensions and maintain the relatively stable function of the dispersion system

Good paint defoamers not only have a good defoaming effect in paint systems, but also maintain defoaming ability at room temperature and under heating environments. In addition, it cannot be compatible with foam system. If the compatibility is good, it will help to produce foam. While the paint paint defoamer has good dispersibility in the foaming system, specifically refers to the uniform and smooth diffusion of the defoamer on the surface, which can cover the foam to achieve the elimination effect. Its working principle is to reduce the surface tension of the liquid around the foam, so that small foam can gather into large foam, and finally foam will burst.
