Explore the key applications of defoamers in various industries
1. Introduction In modern industrial production and daily life, seemingly light foam may have unexpected effects on the production process and product quality. Defoamers, this seemingly inconspicuous "small body", have a "big role" in solving foam problems. Today, let's explore the key applications of defoamers in various industries. 2. Application of defoamers in the chemical industry (I) Foam control during the reaction process Many reaction processes in chemical production will produce foam, such as polymerization reactions, esterification reactions, etc. If these foams are not eliminated in time, they will affect the reaction rate and conversion rate, and may even cause the reaction to get out of control. The addition of defoamers can effectively control the generation of foam and ensure the smooth progress of the reaction. For example, in the production process of synthetic resins, defoamers can prevent foam from accumulating in the reactor and ensure the quality and output of the resin. (II) Product separation and purification In the separation and purification of chemical products, foam can also cause trouble. For example, in distillation operations, foam may cause flooding and affect the separation effect. The use of defoamers can reduce the stability of foam, enable liquids to separate smoothly, and improve the purity and yield of products. 3. Application of defoamers in the food industry (I) Foam elimination in food processing The generation of foam is a common problem in food processing. For example, in the process of bread baking, the stirring of dough will produce a lot of foam, which will affect the volume and texture of bread if not controlled. The appropriate use of defoamers can eliminate these foams, making bread making smoother and more delicate. In beverage production, defoamers can also prevent filling difficulties and poor taste caused by excessive foam. (II) Food preservation and storage Some foods will also produce foam during storage due to the action of microorganisms or other reasons, which will not only affect the appearance of food, but also may cause food deterioration. Defoamers can inhibit the generation of foam to a certain extent and extend the shelf life and storage time of food. For example, in the storage of dairy products, defoamers can prevent excessive foam on the surface of products such as yogurt and maintain the stability and quality of the product. 4. Application of defoamers in the pharmaceutical industry (I) Foam control in the process of drug fermentation The microbial fermentation process in the pharmaceutical industry is one of the important links in drug production, and a large amount of foam is often generated during the fermentation process. These foams not only affect the transfer of oxygen and the exchange of nutrients, but may also cause problems such as contamination, affecting the quality and yield of fermentation. The rational application of defoamers can effect...
