Polyvinyl alcohol with defoamer

Polyvinyl alcohol is an organic compound, white flake, flocculent or powdery solid without taste. Polyvinyl alcohol is an important chemical raw material for the manufacture of gasoline-resistant pipes and vinylon fibers, fabric treatment agents, emulsifiers, adhesives and glues, etc., but when polyvinyl alcohol is added, polyvinyl alcohol has a certain surface Active, due to directional adsorption, the surface tension of the gas-liquid interface is reduced to form foaming, and the surfactant can form a protective film around the bubbles to relieve the impact of the outside world on the bubbles and make the foam more stable. Too much foam can easily affect the product. quality. At this time, you can try polyvinyl alcohol defoamer to defoaming.
