France Differences in Industrial Cleaning paint defoamer(4)





The study of foam can be traced back to Plato's time, but for hundreds of years, people have not formed a unified understanding of the definition of foam. American colloid chemist L · I · Osipow and Dow Corning's R · F · Smith defined foam from the density of foam; Japan's Koichi Ito defined foam from the perspective of foam structure, but ignored the correlation between bubbles; Professor Zhao Guoxi, a famous surface physicist in China, defined foam as: foam is a dispersion system in which gas is dispersed in liquid, gas is a dispersed phase (discontinuous phase), and liquid is a dispersion medium (continuous phase). Bubbles in liquid rise to the liquid surface, forming a bubble aggregate composed of a small amount of liquid that separates gas with liquid film. Scholars at home and abroad agree that foam itself is a thermodynamic unstable system. When the gas enters the solution containing surfactant, it will form a long-term stable foam system.

Industrial cleaning France belongs to chemical agent, that is to use chemical means to eliminate foam. It is mainly composed of polyether and fluorine containing raw materials through a France special process, which is easily soluble in water. It is particularly suitable for continuous defoaming and foam suppression under conditions of high temperature, strong acid and alkali, high shear force, and high pressure. Good high-temperature resistance, acid and alkaline resistance, non floating, non floating oil; It can be widely used for foam elimination and suppression of various harsh systems in a wide temperature range.
