In the process of modern industrial production, the production of foam often becomes a problem that affects production efficiency, product quality and equipment operation. Defoamer, as an efficient foam control agent, came into being and plays an irreplaceable role in many industries. This article aims to briefly introduce the basic concepts, classifications, and application foundations of defoamers in various fields.

Defoamer is a kind of chemical additive specially used to inhibit and eliminate foam in liquid. It usually exists in the form of powder and is easy to disperse in liquid system. It can destroy the surface tension of foam, make foam burst quickly and restrain the generation of new foam, so as to control foam.

Defoamer powder can be classified into various types based on its chemical composition, such as organosilicon, polyether, mineral oil, and composite. Each type exhibits different performance characteristics in specific application scenarios. For example, organic silicon defoamers are widely used in industries such as paint and coatings due to their excellent high temperature resistance and acid alkali resistance; Polyether defoamers, on the other hand, are more suitable for fields such as food and medicine that require high safety due to their good water solubility and biodegradability.

Defoamer powder is widely used in various industries such as papermaking, textiles, wastewater treatment, petrochemicals, and food processing. In the paper industry, it helps improve paper quality and reduce the occurrence of paper breakage; In textile printing and dyeing, it can ensure uniform penetration of dyes and avoid color spots caused by foam; In the food industry, defoamer is used in the production process of beer and dairy products to control the formation of foam and ensure product quality.
