The role of defoamers in antioxidants Some organic compounds that can inhibit or delay the thermal oxidation of polymers and other organic compounds in the air. For example, foods are prone to oxidation and deterioration, and a small amount of antioxidants can be added to extend their storage time. Plastics, synthetic fibers, rubber and other…
Application of alcohol defoamers in papermaking With the development of papermaking industry and the continuous improvement of product quality, the speed of papermaking machines is constantly increasing, and the types of additives added in the wet end are increasing. The generation of foam in the papermaking process and its impact on the quality of paper…
The main uses of non-silicon defoamers Non-silicon defoamers are used in areas with special requirements for surface tension, because most polysiloxane defoamers will strongly reduce interfacial tension. In addition, polysiloxane defoamers cannot be used for coating construction that requires repeated coating, because polysiloxane defoamers may have sliding/anti-sticking effects, and ionic (non-silicon) defoamers are required. Features:…
Application fields of silicone defoamer 1. Mechanism of action: Mechanism of action: The ability of silicone defoamers or foam suppressors is due to their very low surface tension. Silicone compounds (silicone oil) interfere with the surface tension of the gas-liquid interface, resulting in a defoaming effect. When silicone is added to the foam medium, small…
What are the advantages of defoaming agents Since people have a deep understanding of the harm of foam, various types of defoamers have become the most common auxiliary agents in modern industrial production, and the most popular in recent years is Tianjin defoamer. With the rapid development of the national economy, a large number of…
Characteristics and uses of silicone defoamers Silicone defoamer is made of silicone grease, emulsifier, waterproofing agent, thickener and other materials with appropriate amount of water through mechanical emulsification. So what are the properties and characteristics of silicone defoamer? Let’s follow the defoamer manufacturer to learn about it. Its characteristics are low surface tension, high surface…
Surface activity test defoamer At present, surfactants are generally used as bactericides and disinfectants in the aquatic industry. Their bactericidal and disinfecting effects are attributed to their strong interaction with bacterial biofilm proteins, which denatures or loses their functions. These disinfectants have relatively large solubility in water, such as cationic surfactants: quaternary ammonium salts are…
Output of mineral defoamer At present, most domestic water-based paint manufacturers use mineral oil defoamers, and their annual consumption is about 5,000 tons. Most of the products are imported and are very expensive. In order to achieve high-quality localization of mineral oil defoamers and ultimately replace foreign imported products, the author uses homemade additives to…
