Other Applications

Fermentation

The fermentation process can create a lot of unwanted foam during production. Biological organisms which release gases can create problematic foam in tanks and vessels in addition to shear forces. Key instances of foam are in sugar making processes. Use of a proper food grade defoamer will help to control all foam issues and prevent system upsets from occurring.

Metal Cutting Fluids

Metal cutting fluid is used to cool and lubricate knives and mechanical parts in metal cutting, drilling, and grinding. It is composed of a variety of super functional additives with great cooling performance, lubricity, corrosion protection, and degreasing cleaning performance.

Metal cutting fluids can be classified into oil based and water based fluids. Water-based cutting fluids can be classified into emulsion, synthetic cutting fluids, and semi-synthetic cutting fluids. Surfactants in the cutting fluid cause excessively thick working fluids, high friction and heat, and issues with pumping.

PCB Cleaning

Defoamer is used mainly in the inner line production section of exposure, development and etching, and stripping process. The process produces a large number of bubbles because of chemical reactions and mixing which can greatly impact the efficiency of the cleaning equipment. The ingredients used in the process are exposed to alkali and temperatures between 30-40*C. Polyether and silicone emulsions are used in small doses to help control the foam and prevent bubbles from forming.
