Defoamer is a chemical substance widely used in industrial production. Defoamer have the property of reducing the surface tension of liquids and can effectively remove bubbles on the liquid surface.
The working principle of defoamer can be simply summarized into two aspects: reducing the surface tension of the liquid and destroying the bubble structure. First of all, liquid surface tension is the interaction force between liquid molecules, which causes a thin film to form on the surface of the liquid. When bubbles rise in the liquid, they will generate surface tension resistance and form bubbles.Defoamer can reduce the surface tension of liquids, making them less likely to form or burst. Secondly,defoamer can destroy the bubble structure and allow the gas in the bubbles to escape, thus eliminating the bubbles. Defoamer molecules adsorb and expand on the bubble film, changing the physical properties of the bubble film, making it thinner, weaker or even ruptured.

Application fields of defoamer
1. Chemical industry: In the chemical production process, a large amount of gas is often produced, which will form a large number of bubbles and affect production efficiency. The application of defoamer can effectively control bubble generation and improve production efficiency.
2. Food processing: During food processing, for example, a large number of bubbles will be produced during the fermentation of liquids such as beer and juice. If not controlled, it will have an adverse impact on food quality. The application of defoamer can reduce the generation of bubbles and improve the quality and taste of food.
3. Textile industry: During the dyeing and finishing process of textiles, a large amount of dyes and auxiliaries are often required. These substances are prone to generate bubbles and affect the dyeing effect. The application of defoamer can effectively reduce the generation of bubbles and improve the uniformity and quality of dyeing.
4. Oil extraction:During the oil extraction process, oil wells and drilling fluids often contain large amounts of gas, which can form bubbles and reduce the density and stability of the liquid. The application of defoamer can reduce the generation of bubbles and improve the performance of drilling fluids, thereby improving oil production efficiency.
The application of defoamer in industrial production is very important. It can reduce the surface tension of liquids, destroy the bubble structure and effectively control the generation of bubbles.The application of defoamer can improve production efficiency, ensure product quality, and protect equipment and the environment. Therefore, under appropriate circumstances, the use of defoamer is a necessary choice, which can bring better results and benefits to the production processes of various industries.
