In modern industrial production, foam is everywhere: machine tanks for various processing fluids; various industrial cleaning tanks; various industrial and agricultural products and preparations; in various production links of petrochemical industry, water treatment and so on.
       Foam brings various problems to industrial production: in order to prevent foam overflow, the feeding coefficient is forced to be reduced by 30%~50%; foam overflow leads to waste of raw materials; foam takes up space and affects the reaction speed, and the production cycle is forced to extend; foam will affect Product quality, such as coatings, plastic products; the generation of foam, has an impact on the stability of industrial production, causing operation fluctuations and unstable quality.
       The most direct solution to the foam problem is to use defoamers.
