Development of defoamer system for plastic painting water-dispersing paint

摘要

The basic types of defoamers and their applicability in different systems. Determination evaluation criteria steps defoamers. The regularities of the actions of defoamers of different chemical nature, and their mixtures in water-dispersion paint for painting of plastic. Obtained data set for defoaming action of additives of different chemical nature. The dependence of the speed of defoaming from chemical nature of defoamers and their number is studied. Found optimal concentration of defoamers and their mixtures in water dispersion system for painting of plastic products showed the presence of a synergistic effect when using a mixture of defoamers in the present systems. The mechanism of their defoaming actions was suggest.
