The reason for the small intermolecular forces of defoamers
Defoamers are widely used in production and daily life. Similarly, for eliminating harmful bubbles in industrial production, defoamers are also indispensable. The interaction force between defoamer molecules is small, and the surface tension is lower than that of foaming liquid. Only then can defoa

Defoamers have significant effects on the fermentation and defoaming of animal food protein powder
We all know that soybeans, as a major feed, account for a considerable proportion in all feeds. But do you know? Soybeans contain a certain amount of anti nutritional components such as trypsin inhibitors, exogenous lectins, and thyroid hormones. After long-term consumption, animals may experience a

Types and principles of defoamers
Defoamers can be roughly divided into two categories: one can eliminate bubbles that have already been generated, such as ethanol; Another type can suppress the formation of bubbles, such as emulsified silicone oil. The defoamers permitted for use in China include emulsified silicone oil, high carbo

Introduction to the correct use of defoamers
With the rapid development of the national economy, a large number of additives are used in various industries, but this will produce a large number of harmful foam. In order to improve production efficiency, defoamers have become indispensable chemical additives. Organic silicone defoamers, polyeth

Correct use of defoamers
Defoamer, also known as antifoam, is a substance with low surface tension and high surface activity that can inhibit or eliminate foam in liquid. Defoamers are generally made by compounding multiple components. The performance of the main defoamer can be enhanced by compounding surfactants. Whether

Application of defoamers
The effect of defoamers in water-based wood coatings is mainly manifested in two aspects: 1. It can keep the coating fresh, tender, and moldy; 2: It is guaranteed that no cattle foam will be produced during construction.Improper use of defoamers in coating can cause peeling effects, not only leading
