The difference between silica and rubber
For many people, the silicone rubber are often difficult to separate out, even equated, in general, silica gel can be divided according to their nature and components of silicone and inorganic silica two categories.
Inorganic silica gel is a highly active adsorption material, usually react with sodium silicate and sulfuric acid and silica gel structure diagram obtained by aging, acid bulbs and a series of post-processing.
Silica is amorphous material its chemical formula mSiO2. nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica type microporous structure is formed because of the different manufacturing methods. The silicone chemical composition and physical structure, determines that it has many other similar materials to replace the features: high adsorption properties, good thermal stability, chemical stability, high mechanical strength.
The silicone is an organic silicon compound are those containing a Si-C bond, and at least one organic group is directly attached to a silicon atom compound, habits are also often put through an oxygen, sulfur, nitrogen, etc. to make an organic group with silicon the atom connected to the compound as an organic silicon compound. To the silicon-oxygen bond (-Si-O-Si-) polysiloxane skeleton is the largest number of organic silicon compounds, most studies, the most widely used class, more than 90% of the total amount of .
The silicone is a silicone rubber (Q), belonging to a single-component RTV liquid rubber. Once exposed in the air, wherein the silane monomer condensation occurs to form a network structure, crosslinking system, can not be melted and dissolved, and flexible, into a rubbery state, while the adhesive object. Its thermal conductivity is slightly higher than the average rubber, once cured, it is difficult to separate the bonded objects.
The high elasticity of the rubber polymers. Including uncured and cured varieties. Can be divided into natural rubber (NR) and synthetic rubber in two categories. Natural rubber from the latex of rubber plants obtained by processing. Synthetic rubber monomer polymerization or condensation in the system. The uncured rubber commonly known as raw rubber or raw rubber. Vulcanized rubber called vulcanized rubber, commonly known as the cooked rubber or rubber. Widely used in the manufacture of tires, hoses, tape, insulation materials, rubber shoes and other rubber products.
