Apperance: White powder or white grain
Details: Defoamer, also known as anti-foam agent, will produce many harmful foams in the process of industrial production, and it is necessary to add defoamer. It is widely used to remove harmful foam produced in the production process of latex, textile sizing, food fermentation, biomedicine, pesticide, coating, petrochemical, paper making, industrial cleaning and other industries.
Classify: Defoamer is mostly liquid compound products, mainly divided into three categories: mineral oil, silicone, polyether. Mineral oil defoamer usually consists of carrier, active agent and so on. The carrier is a substance with low surface tension, its role is to carry and dilute, and the common carrier is water, fatty alcohol, etc. The role of active agents is to inhibit and eliminate foam, commonly used wax, aliphatic amide, fat and so on. Silicone defoamer generally includes polydimethylsiloxane and so on. Silicone defoamer has poor solubility, fast defoamer and good defoamer at room temperature, but delamination, slow defoamer and poor defoamer at high temperature. Polyether defoamer includes polyoxyethylene propylene oxide glycerol ether and so on. Polyether defoamer has the characteristics of long defoaming time, good effect, fast defoaming speed and good thermal stability.
Product introduction: Solid silicone defoamer is a kind of modified polydimethylsiloxane and other defoamer components refined
The powder type defoamer can be used to eliminate the foam of the water-containing system. Since this product is a powder-like product, its active component
It is dispersed into the foam suppression system by adding a solid carrier, so this product solves the general ordinary silicone emulsion type products
In some high electrolyte, strong acid, strong base, high shear and other systems, the emulsification state is easily destroyed, and the active substances gather quickly
And lead to the defects of natural effect. Therefore, this product has the advantages of fast defoaming speed, long defoaming time and low use cost. On the other
In addition, the product is convenient to use and can be directly added to solid powder products such as metal solid washing agent, washing powder, etc
Add agent to eliminate and suppress bubble source. Because the water content in this product is less, so this product is really convenient to store and transport, not easy to be affected by the environment and temperature
Degree influence, not easy to deteriorate and other advantages.
