Fine chemicals occupy a pivotal position in modern industry, covering many fields such as pharmaceuticals, coatings, papermaking, etc. However, in the production process of these fine chemicals, foam problems are often a headache.

Fine chemical defoamers, as a chemical additive specifically for foam problems, play an irreplaceable role in the field of fine chemicals.

In order to fully mix the raw materials in fine chemical production, stirring is a common operation. Strong stirring will draw a large amount of air into the liquid, increasing the gas-liquid contact area. For example, in paint production, when pigments, resins and solvents are stirred at high speed, air is drawn in to form foam.

Fine chemical defoamers can penetrate into the interior of the foam film and destroy the double-layer structure of the foam film. In this process, the defoamer molecules interact with the substances in the foam film to change the elasticity and stability of the film. Fine chemical defoamers have strong defoaming ability and can effectively eliminate foam at a lower concentration.

Fine chemical defoamers have good water solubility and are easy to disperse in aqueous systems. In addition, they have good chemical stability and can be used in a wide range of temperature and pH. In the alkaline cooking process of the paper industry, it can play a stable defoaming role.

To sum up, fine chemical defoamers play a vital role in various fine chemical fields. With the continuous development of the fine chemical industry, the requirements for the performance, safety and environmental protection of defoamers will continue to increase. By deeply understanding the mechanism of action of defoamers, fine chemical companies can better select and use defoamers, thereby improving production efficiency and product quality.
