In the construction industry, foam is often encountered in the production process of concrete, coating, adhesive and other materials. These foam not only affect the uniformity and quality of materials, but also may reduce the construction efficiency and increase costs. Therefore, defoamers play an indispensable role as key additives in solving this problem in the construction industry.

Defoamer is a chemical substance that can destroy the surface tension of liquid, make foam burst rapidly and inhibit the formation of new foam. According to their chemical composition, defoamers can be divided into various types such as organosilicon, mineral oils, polyethers, fatty acids, etc. Each type has its specific application scenarios and advantages.

Defoamer can reduce the surface tension of foam and make foam wall thinner, thus accelerating the rupture and dissipation of foam. At the same time, some defoamers can also form a film on the liquid surface to prevent the formation of new foam. Reasonable use of defoamers in the production process of building materials can significantly improve product quality, reduce waste rates, enhance production efficiency, and contribute to environmental protection, energy conservation, and emission reduction.
