Organic and inorganic silicone silicone

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.
