Silicone knowledge and industry market analysis

General knowledge of silica gel, silicone based on its properties and components can be divided into two categories of organic silicon and inorganic silicon. Inorganic silica is a kind of highly active material, which is usually used in the reaction of sodium silicate and sulfuric acid. Silica is an amorphous material, its chemical formula is mSiO2. NH2O. In addition to alkali, hydrofluoric acid does not react with any material, it is insoluble in water and any solvent, non-toxic, chemically stable.

Various types of silicon can form different pore structures because of different fabrication methods. Chemical composition and physical structure of silica gel, it has many other similar materials can not replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength.

Silica is an organosilicon compound, contains a Si C key, and at least one organic compound is directly connected to a silicon atom, in accordance with the practice of compounds with silicon atoms are often organic radical with oxygen, sulfur and nitrogen were also used as organic silicon compounds. Among them, silicon bond (- Si - O - Si) poly silicon frame, silicone compound is the most deepest and most widely used for more than 90% of the total. The main component of the safety performance of silica gel is silicon dioxide, the chemical property is stable, and it is not burning.

Silica is an amorphous silica, should control the workshop dust content of not more than 10 mg / cubic meter, need to strengthen the exhaust, the operation when wearing masks. Silica gel has a strong adsorption capacity, can produce the impact on the human skin drying, therefore, the operation should wear good clothes. If the silicone into the eyes, the need for a large number of water washing, as soon as possible to find a doctor.

Blue silica gel contains a small amount of cobalt chloride, toxic, should avoid contact with oral food intake. In the process of using, silica gel adsorption medium water vapor or other organic matter, its adsorption capacity will decline, but it can be repeated use. Application of silica gel was originally applied only to aviation, military and silicone resin is a new type of high-tech materials. Now widely used in various fields of electrical and electronics, textiles, automotive, machinery, leather, paper, metal, paint, pharmaceutical and medical. China organic silicon market demand is huge, the recent domestic production is insufficient. Some large multinational companies in China to establish a production and R & D center, the domestic capital is also actively involved in this area of new materials.

Industry analysis of the current level of domestic technology restrictions, we rely mainly on imports of silicon resin. Over the years the technology has been improved, but there is still a large gap between the material consumption, energy consumption, technical level, especially the quality of. Five leading silica gel in the global market of 80%, now. Four giant layout china.

Industry suggested that multinational giants not only put the Chinese market in the most important position, and let D & R work as close as possible to the Chinese market, in order to gain an advantage. More importantly, not only to better access to customers, shorten the industrial chain, but also to make rapid response to the market.
