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.

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.

The contradiction between supply and demand of bulk commodities is one of the important factors that caused the increase in bulk commodity prices in the first half of the year.With the reasonable adjustment of policies, the current trend of bulk commodity prices has eased compared with the previous period, and the fundamentals of commodity supply are gradually improving. However, changes in overseas liquidity and other factors still cause certain uncertainty, and the trend of different commodities may tend toDifferentiation.

It is a divinyl-terminated polydimethylsiloxane with stable product quality and low volatile content. It is the main raw material for addition-formed liquid silicone rubber, silicone potting compound, silicone gel, etc., and a modifier for compounding rubber.

Conventional low-viscosity 3-50 viscosity, low-viscosity dimethyl silicone oil is colorless, odorless, non-toxic, physiologically inert, good chemical stability, electrical resistance and weather resistance, and has a wide range of viscosity. Therefore, it is used in various sectors of industrial and agricultural production.Chemical products, defense industry, scientific research, medical and health departments, etc., have been extremely widely used.It is used for insulation, compliance, lubrication, shockproof, dustproof oil, dielectric fluid and heat carrier, and used for electronic potting and various silicone rubbers to adjust product hardness.

In recent years, the upstream market of organic silicon has been in short supply, and the price fluctuates greatly, which has a great impact on the downstream industry. With the growth of production capacity, it can not only meet the urgent needs of various industries for silicone products, but also promote the silicone industry to become bigger and stronger. Silicone refers to a large class of compounds that contain carbon-silicon bonds and at least one organic group is directly connected to silicon atoms. Among them, polysiloxanes with silicon-oxygen bonds as the skeleton account for more than 90% of the total amount. , In a narrow sense, organic silicon materials mainly refer to polysiloxanes. Polysiloxane downstream products generally include silicone rubber, silicone oil, and silicone resin, of which silicone rubber can be divided into high temperature glue, room temperature glue, and liquid glue. Silicone has a wide range of end uses, such as construction engineering, textiles, electronics, transportation, petrochemicals, aerospace, new energy, medical machinery, daily chemicals, personal care, etc.

Briefly describe the application problems and solutions of silicone oil softener in the printing and dyeing industry.Take you into the world of silicone oil: There are many varieties of silicone oil emulsion finishing agents, and the quality is uneven. There are cationic, anionic, non-ionic, etc., modified amino silicone oil and linear silicone oil and so on. Generally, the following points should be paid attention to when using silicone oil for soft finishing.

Bing Dundun is actually an ordinary plush panda doll, but compared with the common pure plush mascot, it has an extra silicone shell, and the Bing Dundun with the shell is more difficult to deal with in details. It is also the main reason why the production cycle of Bingdundun is longer than that of pure plush toys. However, consumers who get Bingdundun also have a trouble, the outer shell of Bingdundun will turn yellow. The friends who have used the transparent silicone protective case for their mobile phones must have a deep understanding. After a period of use, it will turn yellow and affect the appearance.
