Organic and inorganic silicone silicone In general, the silicone can be divided according to their nature and composition of organic and inorganic silicone silicone two categories. Inorganic silica is a highly active adsorption material , usually with sodium silicate and sulfuric acid , and after a series of aging processes , such as acid bubbles in the system. An amorphous silica material , its chemical formula is mSiO2. nH2O. Insoluble in water and any solvent , non-toxic , odorless , chemically stable, does not react with any substance except alkali, hydrofluoric acid . Various types of silica are formed in different manufacturing methods of different pore structure . Chemical composition and physical structure of silica gel , and determines that it has many other similar materials difficult to replace characteristics: high adsorption properties, good thermal stability, chemical stability, high mechanical strength. Figure - Silicone Rubber The main ingredient is silica, silica gel , chemically stable , does not burn . Silica gel is an amorphous silica dust content of the workshop should be controlled less than 10 mg / cubic meter, the need to enhance ventilation, wear a mask when operating . Silicone has a strong adsorption capacity, can produce human skin drying effect , therefore , the operation should wear good clothes. If the silicone into the eyes , flush with lots of water and seek medical treatment as soon as possible . The basic structural unit of the silicone product is made of a silicon - oxide chain section composed of a silicon atom through a side chain with various other organic groups . Compared with other polymer materials, the most prominent performance silicone products are: 1 . Temperature characteristics Silicones are silicon - oxygen (Si-O) bond of the main chain structure , C-C bond energy of 82.6 kcal / mol , the bond energy Si-O bond in the organic silicon is 121 kcal / mole , so the high thermal stability of silicone products , high temperature ( or radiation ) molecular bond is not broken , do not break down . Silicone is not only to high temperature , low temperature resistance, but also can be used in a very wide temperature range . Whether it is physical or chemical properties and mechanical properties, temperature dependence is very small. 2 . Weatherability Silicones of the main chain is -Si-O-, unparalleled key exists , it is not easy to be decomposed by ultraviolet light and ozone. Better than other silicone polymer material thermal stability and resistance to radiation and weathering capabilities . Silicone natural environment life of up to several decades. 3 . Electrical insulating properties Silicones have excellent electrical insulating properties , dielectric loss , resistance, voltage, resistance, arc resistance, corona , volume resistivity and surface resistivity of the top in the insulating material etc. , and their performance is affected by temperature and frequency electrical little effect . Therefore, they are a stable electrically insulating material , are widely used in electronics and electrical industry. Silicones have excellent heat resistance in addition , it also has excellent water repellency , the electrical equipment which is used under wet conditions having a high reliability protection . Recommended article : Human silicone introduction 4 . Physiologically inert Silicone compounds are known in the least one active compound . They are extremely resistant to biological aging , and animal body without rejection , and has better anti- clotting properties.
