The silicone trademark (also known as Siliconon trademark) is made of liquid silicone oil and solid silicone heated in a mold by a vulcanizing machine. According to its properties and components, it can be divided into two categories: organic siliconum and inorganic siliconum. Inorganic siliconum is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate and sulfuric acid, and a series of post-treatment processes such as aging and acid bubble. Silica gel is insoluble in water and any solvent, non-toxic tasteless, environmental protection, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substances. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials are difficult to replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc.
