According to the analysis of the silicone industry.,Who as early as possible to expand production capacity and reseach capability,who will be able to take a larger market. The organic silicon industry is a capital-and technology-intensive industries, a higher threshold and high energy consumption, easily contaminated. At present, China is no shortage of funds, lack of technology and innovation ability and own brand.
Siilicone is an emerging high-tech materials that initially only used in aviation, military areas and then gradually,widely applied to various fields of electrical and electronics, textile, automobile, machinery, leather, paper, metal, paint, pharmaceutical and medical . The industry believes that Chinese silicone market demand is huge, When some large multinational corporations have production and R & D center in China ,many domestic private companes are also actively involved in this field of new materials.
In the next three to five years, the key machine of silicon industry rely heavily on imported our experts predict. It will be important stage in the development of the key machine of silicon industry. In 2010, China will exceed the U.S. as the world's largest silicone producer and consumer countries. But now China's silicone is mainly dependent on imports. According to statistics, from 2000 to 2006, the country market silicone characterization of consumption of the average annual growth rate of 30%, more than two-thirds of which are dependent on imports. The next few years, China silicone market will still be in short supply, to rely heavily on imports.
The key machine of silicon industry dependent on imports, the industry believes. Mainly due to the limitations of the domestic technology level. United Securities analyst, said Xiao Hui, domestic for many years technical improvements, but the material consumption, energy consumption, there is a big gap on the technical level, in particular, the quality is hard to break.
Multinational giants have come to China to open up the market. Industry leader Dow Corning in 1973, began to enter the Chinese market, multinational companies stare at the huge demand of China, and see China silicone market. So far the total investment in China has more than 40 million U.S. dollars to build a complete industrial chain, completed China's strategic layout.
A joint venture with Zhejiang Xinan Chemical Industrial Group, the world's second largest the silicone enterprises Momentive said. Investment of nearly $ 100 million building an annual output of 100,000 tons of organic silicon monomer project. Previously, Momentive has four organic silicon production plant in Shanghai, Shenzhen, Nantong.
Five giants monopolize the global silicone Bacheng market now. The Big Four has the layout of China. To industry sources, the multinational giants not only the Chinese market on the most important position, and let the R & D work as close as possible to gain an advantage. It is reported that the Momentive loaded with the world's fourth R & D center in Shanghai. In this regard, paragraph Ying explained: R & D center in China, talent better access to customers, shortening the industry chain to respond quickly to market.
But industry experts believe that, or inflection point in the silicone market is still in short supply. Industry inflection point may occur in 2010, supply exceeds demand.
The gross profit of some silicone-based products in 30-50% silicone phase as a new data for conventional materials have many advantages, the industry pointed. Is widely used. The temptation of high profits, some private enterprises have started the construction of organic silicon production line.
In general, the silica gel according to their nature and composition can be divided into two major categories of organic silica and inorganic silicone.
Inorganic silica is a highly active adsorption material, usually sodium silicate and sulfuric acid reaction, and aging, acid bulbs and other post-processing system. The silica gel is amorphous material, chemical formula mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica manufacturing methods and the formation of different porous structure. The chemical composition and physical structure of the silica gel, decided it difficult to replace the characteristics of many other similar materials: adsorption properties, thermal stability, chemical stability, high mechanical strength.
Organic silicone is a silicone compounds that contain Si-C bond, and at least an organic base is directly connected with the silicon atoms in compounds, often customary by oxygen, sulfur, nitrogen organic base with silicon atoms connected compounds as organic silicon compounds. Among them, the silicon-oxygen bond (-Si-O-Si-) for the skeleton composed of polysiloxane is the largest number of organic silicon compounds, the deepest, the most widely used class, accounting for more than 90% of the total amount of .
Silicone main component is silicon dioxide, chemically stable, and does not burn. Silica gel is an amorphous silica to control dust in the workshop content is not greater than 10 mg / cubic meter, the need to strengthen the exhaust, wear a mask operation.
Silica gel has a strong adsorption capacity of human skin to produce dry, therefore, the operation should wear good clothes. If the silicone into the eyes, required copious amounts of water and seek medical treatment.
Blue silicone because it contains a small amount of cobalt chloride, toxic, and should be avoided and food contact and inhalation of the mouth, such as the occurrence of poisoning should immediately seek medical treatment.
Silica gel in the course of adsorption of water vapor in the media or other organic substances, the adsorption capacity decreased, can be reused after regeneration.
