Polyvinyl Alcohol Glue Antifoaming Agent Polyvinyl Alcohol Glue is white glue, which is a chemical synthetic glue. The adhesive made of polyethylene and aldehyde compounds is light white and thin, with strong adhesion and strong moisture resistance. The glue on the back of stamps in my country is mainly made of this raw material. Polyvinyl alcohol glue is made of organic chemical and chemical fiber raw materials, surface active material + other additives + water in a certain ratio to form a colloidal substance, but polyvinyl alcohol will produce a large amount of foam during the dissolution process, and the foam will last for a long time. Retention directly affects the quality and use of glue, which will eventually lead to a decrease in productivity and an increase in production costs. For the first type of foam problem, we can use polyvinyl alcohol glue defoamer to remove foam and reduce the impact.

Reasons for foaming of polyvinyl alcohol glue
1. PVA has a certain surfactant, so it is easy to produce foam;
2. Encountered with strong impact and agitation, it is easy to produce a large amount of foam;
3. The gas produced by the thermal decomposition or fermentation of the treatment agent produces a large amount of foam;
The harm of polyvinyl alcohol glue foam
1. Reduction of production capacity: In order to be able to contain foam and prevent overflow, in the dissolution process, the amount of feed in the cooking pot and other equipment should be reduced by about 10 to 30%, which will lead to a decrease in production;
2. Rising production cost: As the foam stays in the solution, the reaction cycle is prolonged, the power consumption rises, and the output rate of a single tank will decrease, which ultimately leads to an increase in production costs;
3. The foam in the solution may eventually be brought into the final product, thereby affecting the use and quality of the glue.

Polyvinyl alcohol glue foam solution
The reason why polyvinyl alcohol glue foams is inseparable from its technological formula. Too much glue foam will affect work efficiency, later use and production, so the easiest way to suppress glue foam is to add "defoamer". Defoaming is a kind of chemical defoaming through polyvinyl alcohol glue defoaming agent. Nanhui defoaming agent manufacturer specially developed and designed a type of compound defoaming agent to solve the problem of polyvinyl alcohol glue foaming. It is easy to use and defoaming. Fast foam suppression and lasting characteristics.
