Defoamer: Foam Busters for Industrial Production

In the huge system of modern industrial production, the appearance of foam is often like an uninvited guest, which brings a lot of troubles to production. Whether it is chemical, food, pharmaceutical, or paper, printing and dyeing industries, the production of foam not only affects the production efficiency, but also may have a serious impact on product quality. And defoamer, as a special solution to the foam problem, is gradually becoming an indispensable role in industrial production.


Chemical industry is one of the most widely used fields of defoamer. In many chemical reactions, the formation of bubbles is almost inevitable due to the complexity of the reaction system and the production of gases. For example, in the polymerization reaction, the decomposition of the initiator and the polymerization of the monomer often produce a large amount of gas, which forms a foam in the liquid, which not only affects the uniformity of the reaction and the efficiency of mass and heat transfer, but also may cause the reaction to run out of control. The addition of defoamer can quickly reduce the surface tension of the foam and make the foam burst, so as to ensure the smooth progress of the reaction. In the production process of synthetic rubber and plastics, the use of defoamer can effectively improve the quality and yield of products and reduce the rate of defective products.


The food industry has more stringent requirements for defoamer because it is directly related to the health of consumers. In the food processing process, such as the production of beverages, beer, dairy products, baked goods, etc., the production of foam will affect the appearance, taste and stability of the product. For example, in the beer brewing process, the control of foam is crucial. Excessive foam will not only affect the filling and storage of beer, but also affect the flavor and taste of beer. High-quality defoamer can quickly eliminate foam without affecting the quality of beer and ensure the clarity and taste of beer. In the production of dairy products, defoamer can prevent the foam of milk in the process of stirring, homogenization, etc., to ensure the stability and quality of products.


The safety and purity requirements of defoamer are extremely high in the pharmaceutical industry. In the process of drug synthesis, fermentation, concentration, etc., the existence of foam may affect the quality and yield of drugs. For example, in the fermentation production of antibiotics, foam can affect the delivery of oxygen and the growth of microorganisms, thus reducing the production of antibiotics. The use of defoamer requires strict control of its residual amount to ensure the safety of the drug. At present, many pharmaceutical companies have adopted defoamer in accordance with the Good Manufacturing Practice (GMP) to ensure the quality and safety of drugs.


The paper industry is also an important application area of defoamer. In the process of papermaking, pulp preparation, paper making and coating will produce a lot of foam. These foams will affect the quality of the paper, such as causing holes, spots and other defects in the paper. The defoamer can quickly eliminate the foam in the pulp and improve the quality and production efficiency of the paper. During the coating process, the defoamer can also prevent bubbles from appearing in the coating, making the coating more uniform and smooth, and improving the printability of the paper.


The printing and dyeing industry often encounters foam problems in the process of dyeing and printing. Foam will affect the uniform distribution of dyes, resulting in unsatisfactory dyeing and printing results. The use of defoamer can effectively eliminate foam and ensure the quality of dyeing and printing. At the same time, the defoamer can also reduce the waste of dyes and reduce the production cost.


In addition to the above industries, defoamer is also widely used in sewage treatment, oil exploitation, electronics industry and other fields. In the sewage treatment process, aeration and stirring operations will produce a lot of foam, defoamer can effectively control the generation of foam, to ensure the normal operation of sewage treatment. In oil exploitation, defoamer can be used for demulsification and dehydration of crude oil to improve the quality and yield of crude oil. In the electronics industry, defoamer can be used in processes such as cleaning and etching to prevent foam from causing damage to electronic components.


As a foam buster in industrial production, defoamer plays an important role in various industries. With the continuous development of industrial production and the continuous improvement of product quality requirements, the performance and quality of defoamer are also constantly improving. In the future, defoamer will continue to play an important role in industrial production and provide strong support for the development of all walks of life.
