In recent years, the production capacity and output of organic silicon monomers in my country have continued to grow. By the end of 2021, the production capacity and production of methyl siloxane in China will exceed 60% of the global total, and the consumption will exceed 50% of the global total, and it is still in a stage of rapid development. It is estimated that by the end of the "14th Five-Year Plan", the production capacity of organic silicon monomers in China will exceed 6 million tons per year, accounting for more than 70% of the global production capacity of organic silicon methyl monomers. However, from the analysis of the import and export status of siloxanes in the primary form in China, high-end silicone products still rely on imports, and the phenomenon of big but not strong still exists.

Silicone Classroom - What is amino silicone oil? What are its categories?

Silicone emulsion is an emulsion composed of oil-in-water silicone oil, water and surfactants. Silicone emulsion is mainly used as a silicone fabric softening agent. The first generation of silicone fabric finishes were mechanical mixtures of dimethicone and hydrosilicone (and their derivatives). The second generation of silicone fabric finishing agent is hydroxyl-terminated polydimethylsiloxane emulsion, which is emulsified from octamethylcyclotetrasiloxane monomer, water, emulsifier, catalyst and other raw materials under certain conditions. aggregated. Since polymerization and emulsification are completed in one step, it has the advantages of short working hours, high work efficiency, simple equipment, and easy operation. The obtained emulsion is very stable, the particles are very uniform, and the obtained polymer has active groups (hydroxyl groups) at both ends. ) can further react to form a film, which is beneficial to improving the application effect of the emulsion, which is beyond the reach of mechanical emulsified silicone oil.

Silicone light diffusing agent is an organic light diffusing agent. It is a polymer microsphere with a three-dimensional structure connected by silicon-oxygen bonds. This light diffusing agent itself is a white powder that is added to resins of different materials. , a kind of fine transparent glass spheres are evenly dispersed in the matrix. Through the difference in refractive index with different substrates, the light source is refracted penetratingly, changing the path of the light, and achieving uniform light and light transmission. Purpose.Meet the requirements of haze value and light transmittance at the same time.

At present, there are many varieties and models of commercial silicone defoamers at home and abroad, with different properties. Generally, they can be divided into oil (ointment) type, solution type, emulsion type, solid type and modified silicone oil type.

Little knowledge about silicone-Introduction to silane coupling agent products

Electronic potting glue is a kind of potting material that needs to be used in the manufacturing process of electrical appliances and electronic components. The microcomputer control board of the automatic washing machine needs to use electronic potting glue for potting in the manufacturing process. Then, the fully automatic Why do washing machines need electronic potting before potting?

Industry knowledge: What kinds of glue are commonly used in circuit boards?

Due to its excellent electrical insulation and mechanical properties, silicone gel is widely used in the packaging insulation of IGBT devices. Xu Jiayu, Li Xuebao, Cui Xiang, Mao Yuan, and Zhao Zhibin, researchers from the State Key Laboratory of New Energy Power Systems (North China Electric Power University) and the Department of Electrical and Computer Engineering of Virginia Tech, published in the second issue of "Journal of Electrotechnical Society" in 2021 In the previous article, the preparation process of silicone gel was introduced in detail, the degassing curve was improved, and the problem of air bubbles at high temperature in samples prepared by traditional processes was solved.

Silicone oil is a liquid polyorganosiloxane with excellent high and low temperature resistance, chemical stability, shear resistance, viscosity-temperature characteristics and high compressibility. Vibration reduction products based on silicone oil are widely used in electrical and electronic equipment, high-rise buildings, bridges and weapon platforms. A large number of related patents have been applied abroad, but there are still few domestic researches in this area.
