Performance And Use Of Polyether Defoamer

Polyether defoamers are non-ionic surfactants with excellent defoaming and anti-foaming functions. They are non-toxic, insoluble in water, and easily soluble in organic solvents. They can be used alone or in emulsions.

Polyether defoamers can be divided into polyol type, fatty acid ester type and amine ether type according to the different initiators used in the synthesis. Among them, polyol type and fatty acid ester type are the most widely used.

Main ingredients of polyether defoamers:

Polyether defoamers are compounded with special modified polyethers and fluorine-containing raw materials through special processes. According to these different additives, polyether defoamers can be divided into polyols, fatty acid lipids and amine ethers. These three different types of polyether defoamers have their own characteristics, colorless and transparent, fast defoaming, and long-term anti-foaming.

Defoaming principle of polyether defoamers:

When polyether comes into contact with water, the temperature rises from the low-temperature dissolution state in water to the temperature at which turbidity appears is its turbidity point. The foaming system will also exceed the temperature of the turbidity point as the water temperature exceeds the temperature of the turbidity point. Only then will the polyether defoamer play its role, which can quickly defoam and control the generation of foam.

How to dilute the polyether defoamer:

1. The polyether defoamer is acid- and alkali-resistant and high-temperature-resistant. It can be diluted with water at will without affecting the appearance. It is advisable to add the defoamer in small amounts and multiple times.

2. The polyether defoamer can be heated and sterilized with the original liquid and the fermentation base material into the tank, or it can be prepared into a water emulsion and directly steam sterilized and then "flow-added" into the tank for defoaming; the defoamer emulsion preparation tank has a mechanical stirring device to make the defoamer fully dispersed and evenly distributed to achieve the ideal defoaming effect.
