What Does An Industrial Defoamer Consist Of? What Are The Main Ingredients?

In fermentation, coating, paper making, printing and dyeing and other industrial production, due to the use of a variety of chemical additives, or part of the process operation will easily lead to the emergence of a large number of bubbles, and the surfactant factor in the additives will let the foam stable existence, and industrial defoaming agent has low surface tension, can be spread on the surface of the foam system, reduce the foam viscosity, so that the foam drainage rapidly increase. In order to achieve the purpose of defoaming, the reason why the industrial defoaming agent defoaming effect is so strong, because its main components played a great role.

Industrial defoamer application scenario

Industrial defoamer is not only composed of one substance, but contains a variety of components, less than 2~3, more than 5 kinds, which its main components include: the main anti-foam agent, carrier, stabilizer or compound, emulsifier or expansion agent, the main components of the following effects

1. The main anti-foam agent

Antifoaming agent is the main active ingredient in industrial antifoaming agent. It is usually insoluble granular material, such as hydrophobic silica treated with silicone oil, fatty amine, paraffin, etc. Therefore neither soluble in carrier, nor soluble in foaming medium, commonly used anti-foaming agents are: polysiloxane, silicon dioxide or some non-oil soluble polymers. At the same time, it should adopt a reasonable proportion in the preparation of defoaming agent, so as to effectively reduce the surface tension of bubbles, so that the anti-bubble effect of defoaming agent to achieve better.

2. Carrier

The carrier mainly supports the main antifoam agent, accounting for the majority of the antifoam agent formulation, and water is also a convenient and economical carrier. The existence of the carrier can make the defoaming factor and the foaming system fully integrated, which is convenient to incorporate them into the foaming system. They are usually based on oil or water, but sometimes other substances such as fatty alcohols, fatty acid esters or solvents are used.

3. Emulsifier and development agent

Their presence can make the active ingredients dissolve in water better, thus improving the emulsification and defoaming effect of industrial defoamer. The active ingredients of the defoamer can be dispersed quickly in the foaming system, so that the defoamer can contact the surface of the foaming liquid more quickly, so as to improve the defoamer efficiency.

4. Stabilizer or compound

They are an additive that can improve the stability and storage time of industrial defoamer, while the stabilizer of water-based industrial defoamer is usually understood as a preservative, which can avoid bacterial contamination of the defoamer during storage. At the same time, thickening agent can also be used as a stabilizer, such as carboxymethyl cellulose can improve the viscosity of defoamer, maintain the stability of water-based defoamer.
