For silicone defoamers and silicone oil defoamers, I believe many people and I are not very clear about them, so before I wrote this article, I also collected some information and learned a bit. The following new Wan achievements bring you to see what is a silicone defoamer, what is a silicone oil defoamer, what is the connection and difference between the two.


Generally, silicone oil refers to a polysiloxane that maintains a viscous liquid state at normal temperature, and silicone refers to polysiloxane. Therefore, silicone oil is considered to be silicone, and silicone is silicone oil, but the form of the two is different. But the chemical composition is the same. For example, water and ice, the two exist only in different forms. Can you say that they are two kinds of substances? Of course not.


Silicone exists in many forms and can be divided into: silicone chemical reagents, silicone oil, high temperature vulcanized silicone rubber, liquid silicone rubber, silicone resin, composites, etc., so silicone oil is one of many silicone forms.


To understand the relationship between silicone defoamers and silicone oil defoamers, let's take a look at the characteristics of silicone defoamers. What is the difference between ordinary defoamers?


(1) Silicone defoamers are dispersed slowly in water and oil systems.


(2) It has a low surface tension and can quickly defoam.


(3) Good chemical stability and heat resistance, and can be defoamed in a neutral foaming system and a high temperature environment.


(4) Silicone oil is physiologically inert, and it is configured as a defoaming agent, which does not pose a safety threat to the human body.


(5) The silicone defoamer has a small biochemical oxygen demand (BOD) and can be used for defoaming of the sewage system without increasing the load of the sludge.


(6) There are many types, and a variety of foaming systems are available.
