In all walks of life, bubbles are a common problem, the generation of bubbles will affect the production, and even affect the quality of the product, how to efficiently and conveniently eliminate or control the foam, is a problem that every manufacturer has to consider, so the defoamer has become the best way for each manufacturer to solve the foam problem.

Defoamer, as the name suggests, is a chemical agent to eliminate foam. After the silicone defoamer is added to the foaming system, it can be quickly dispersed, and the surfactant molecules are oriented on the surface of the bubble. When the silicone defoamer reaches a certain concentration, the surfactant molecules will form a film on the bubble wall and reduce its surface tension. Thus, the gas-liquid contact surface is increased, and the formed bubbles are not easy to merge and burst.


Silicone defoamer has the following characteristics compared with other types of defoamer:


1, wide application, due to the insolubility of silicone oil to various substances, so wide application, can be used for water system defoaming, but also can be used in the oil system.


2, small surface tension, good defoaming efficiency.


3, good thermal stability, can be used in a wide temperature range


4, good chemical stability, as long as the preparation is reasonable, silicone defoamer is allowed to be used in the system containing acid, alkali and salt.


Silicone defoamer not only has good defoaming and defoaming effect, but also has the characteristics of low dosage, good chemical inertia, and can play a role under harsh conditions. In recent years, it has achieved rapid development, and new varieties and models suitable for different use environments are constantly produced, and the application surface is constantly expanding.
