Properties and applications of polyvinyl alcohol defoamer

Polyvinyl alcohol defoamer is a kind of surfactants commonly used in the chemical field, and it is widely used in the chemical industry. Its main role is in the production process, can effectively reduce the foaming phenomenon, also known as foaming agent or foam inhibitor.

Properties of polyvinyl alcohol defoamer

1. With low surface tension, it can effectively destroy the tension on the surface of the liquid, so that the liquid molecules repel each other, and the molecular combination will no longer occur to produce foam.
2.Polyvinyl alcohol defoamer has good dispersion performance, which can re-disperse dispersed bubbles in the liquid, thereby avoiding foam deposition and reducing energy waste.
3. PVA defoamer can form a relatively stable dispersed liquid system, making its distribution in the liquid more uniform, thereby reducing the generation of foam.
4. Its role is to change the interaction force between molecules, and the physical and chemical properties of the solution have no obvious relationship, will not affect the composition of the solution and chemical reaction.

The role of PVA defoamer in production

1. Reduce energy consumption
The application of PVA defoamer can effectively reduce the resistance of air and bubbles to liquid, reduce the consumption of pumping energy and stirring energy, and thus save energy.
2. Improve production efficiency
In some special occasions, the generation of foam will have a negative impact on production efficiency, the use of PVA defoamer can effectively reduce the generation of foam and improve production efficiency.
3. Improve product quality
The use of polyvinyl alcohol defoamer can effectively control the foam generation, reduce the tension of the liquid surface, make the product surface more flat and smooth, so as to improve the product quality.

To sum up, PVA defoamer is one of the excellent surfactants, which is widely used in various industrial fields. In practical application, we should choose the corresponding defoamer according to the specific production needs to achieve the best effect.
