PVA powder Deforming methods:

A:Before dissolving,Please immerse PVA into the cool water to make it swollen,And expel the air and volatiles in PVA as much as possible.Then elevate the temperature gradually,Which can efficiently prevent formation of any foam.

 

B:If foams are produced.It is recommended to stop steam heating and agitating.After the foams disappear automatically.Please Elevate the temperature gradually with agitation again.Repeatedly doing  so two or three times.The foams will be reduced significantly

 

PVA powder Application:

Polyvinyl Alcohol can be widely used as protective colloid or Thickener for the emulsion pollymerization of Vinyl Acetate(VAc) or VAc/Acrylate.....
