Antifoaming agent is an additive that can reduce the surface tension of water, solution, suspension and other substances, prevent the formation of foam, or reduce or even eliminate the original foam. Its working principle is to destabilize the bubble wall and burst it, thereby releasing the trapped gas.
Defoaming agents have the following characteristics:
1. It has strong foaming ability and low dosage;
2. Adding it to the foaming system does not affect the basic properties of the system, that is, it does not react with the system being defoamed;
3. Chemistry It has stable properties and strong oxidation resistance;
9. It has low solubility in foaming solutions.
Classification application
Defoaming agents according to chemical properties It can be divided into silicone type, polyether type, polyether modified polysiloxane type, etc.; according to its characteristics, it can be divided into anti-foaming type defoaming agent and anti-foaming type defoaming agent.
Defoaming agents are widely used in coatings, adhesives, detergents, cutting fluids, pesticides, medicine and other industries.
