< p > silicone alias: silica gel is a highly active adsorption material, amorphous materials, the chemical formula for mSiO2 · nH2O; In addition to the strong alkali, hydrofluoric acid does not react with any material, insoluble in water and any solvents, avirulent insipidity, stable chemical properties. Various types of silicone because of the different manufacturing methods and form different microporous structure. Chemical components and physical structure of the silica gel, made with many other similar materials difficult to replace features: high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc. Silica gel according to the size of the aperture is divided into: macroporous silica gel, coarse pore silica gel, b-type silica gel, silica, etc. < / p > < p > < / p > < p > silica gel is a kind of inorganic rubber containing different species composition of silica particles and combined with the formula. Silica gel due to its superior reliability, longevity and extreme temperature adaptability and stability and widely used. It will not deformation, also won't under extreme temperature exposure and damage. Liquid silicone can exist and depends on the application and forming solid and food processing method. Silicone baking pan is high temperature molding method. < / p > < p > < / p > < p > all kinds of silica gel due to its different manufacturing methods and form different microporous structure. Silica gel relative to other similar material has many advantages, such as high adsorption properties, stable chemical properties, In addition to the strong alkali, strong acid does not react with any material) , good thermal stability, high mechanical strength, etc. < / p > < p > < / p > < p > glue according to the size of the aperture is divided into: macroporous silica gel, B type of silica gel, coarse pore silica gel, silica; According to its shape is divided into extrusion silicone and moulded silica gel; According to the nature and composition can be divided into two categories, organic silicone and inorganic silica gel. Chemical components and physical structure of the silica gel, determines it has many other similar materials difficult to replace features: high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc. Silica gel has a strong ability of moisture absorption, so should be stored in a dry place, want to have is put aside frame between packaging and ground. Packaging has a steel drum, drum, paper box, plastic bottles, polyethylene plastic compound bag, flexible container bags, etc. In the process of transportation should avoid to drench, be affected with damp be affected with damp, and exposure. < / p >
