What is organic silica and inorganic silicone?

1, silicone Description: silicone rubber are special synthetic rubber, which is divided into solid and liquid according to the form. Liquid is divided according to the curing temperature and high-temperature curing RTV type. The basic structural unit of the silicone product is made of a silicon - oxygen link constituted by the side chain is bonded to silicon atoms with various other organic groups. Therefore, the structure of silicone products containing both organic groups, but also contains an inorganic structure, this particular composition and molecular structure of organic matter that it set features and inorganics-in-one. Product features: Temperature characteristics, weather resistance, electrical insulation properties, physiologically inert, low surface tension and low surface energy. Use of silicone: Silicone having these excellent properties, so its wide range of applications. It is not only as aviation, cutting-edge technology, military technology sector specialty materials, but also for the various sectors of the national economy, its application has been extended to: construction, electrical and electronics, textile, automobile, machinery, leather, paper, chemicals, light industry, metal and paint, pharmaceutical and medical. 2, inorganic silicone Description: inorganic silicone formula xSio2 · yH2O. Transparent or white granular solid, is a highly active adsorption material, usually with sodium silicate and sulfuric acid, and after a series of processes after aging, acid bulbs and the obtained amorphous machine manufactures. It exists in nature by the mineral was washed, processed into granular or bead-like, the main component of inorganic silica is silica, the silica is a sodium silicate with sulfuric acid made of machine-made amorphous finished. The washed silica gel by inorganic mineral existing in nature, post-processed into a granular or bead form. Inorganic silica structure very much like a sponge by interconnecting pores holes constitute a large surface area of the adsorption system can absorb and store water vapor. In 100% humidity condition, it can absorb and condense the equivalent of 40% of its own weight of water vapor. High adsorption performance, can absorb a variety of substances. Dilute sulfuric acid (or hydrochloric acid) in an aqueous solution of sodium silicate and allowed to stand, it will become a hydrous silicate gel and solid state technology, good thermal stability, chemical stability, high mechanical strength. Uses: inorganic silicone choice of packaging materials is very broad, generally OPP / PE, PET / PE film, non-woven composite paper. For gas drying, gas absorption, liquid dewatering, chromatography, etc., are used as catalyst. Such as adding cobalt chloride, dry blue, red after absorbing water.
