Defoamer powder is a chemical powder specifically designed to eliminate and suppress the formation of bubbles in liquids. It rapidly ruptures and dissipates bubbles by breaking the surface tension of the bubbles. The principle is that defoaming powder particles can quickly disperse into the liquid, adsorb on the surface of bubbles, reduce their surface energy, and thus promote the merging and rupture of bubbles.

Defoaming powder is widely used in many industries, including but not limited to: in the production process of beverages, beer, dairy products, etc., defoaming powder can effectively remove foam generated in the process of mixing and fermentation to ensure product quality. During the manufacturing and construction process of coatings and paints, defoamers can significantly reduce bubbles, improve the smoothness and aesthetics of coatings. In oil exploitation, oil refining and chemical production, defoaming powder is used to control oil and gas foam to ensure normal operation of equipment and process efficiency. In sewage treatment and industrial wastewater treatment, defoamer can effectively remove foam, improve water quality and promote subsequent treatment process.

Compared to other defoamers (such as liquid defoamers), defoaming powder has the following advantages: the powder form is easy to store and transport over long distances, reducing volume and weight. Easy to weigh, easy to control the amount added, and avoid waste. It can quickly disperse in various liquid systems and is suitable for different process conditions. Some defoamers use natural or biodegradable ingredients, which have minimal impact on the environment. When selecting, the properties of the liquid, process conditions, and required defoaming effect should be considered. When using, the recommended dosage should be accurately added and thoroughly stirred to ensure uniform dispersion. At the same time, pay attention to keeping the usage environment clean and avoiding impurity contamination.

With the improvement of environmental awareness and the increasing demand for product quality in various industries, green, efficient, and multifunctional defoamers will become the mainstream in the market. In the future, the research and development of defoaming powder will pay more attention to the application of environmentally friendly materials, optimization of performance, and integration of intelligent control technology.
