Antifoam and defoamer

Problems caused by creating foam in industries

Foam is created by the dispersion of air or gases in the liquid or due to the presence of compounds and solutes in the water and remains stable in the system. The presence of foam will cause serious problems in the industries and if not controlled, it will cause the production tanks to overflow and reduce the production capacity, increase the costs due to bubble corrosion and increase the time of the production process. Anti-foam or anti-foam or defoamer is used to prevent the formation of foam or to eliminate the foam produced in industrial processes. Foam occurs as an unwanted byproduct in the production process of a product, especially in biochemical processes. Foam formed in industrial processes creates problems. Among these problems, we can point out the formation of bubble corrosion on metal surfaces, fluid overflow from production tanks, disruption in the product production process, etc. To solve this problem, you should use the appropriate antifoam.

Good antifoam properties

The choice of antifoam type depends on factors such as the cause of foam formation, the operating conditions of the process, and the type of process fluid. To choose the right antifoam, the floor collapse test should be performed with different antifoams and it should be noted that the used antifoam does not react with the process fluid and does not lose its effectiveness in operational conditions. Antifoams are usually insoluble in the process fluid and disperse in the fluid, and one of its important features is its high surface activity. One of the main features of these materials is that they spread easily and quickly on the floor surface. The characteristic of these compounds is their low viscosity and fast spreading conditions on foam and foam.

How anti-foam works

Antifoams destabilize foam layers and cause bubbles to accumulate on the surface of liquid and air, and ultimately lead to the loss of foam formed on the liquid. The performance of an antifoam depends on several factors, including whether the foam is micro or macro, operating conditions, acidity or alkalinity of the environment, etc.

All kinds of anti-foam and anti-foam solutions

Antifoams have industrial and edible grades and different bases of alcohol, silicone, oil, combination, etc. Below are the antifoams produced by Abrizan company:
