In the same way, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.It is divided into extruded silica gel and molded silica gel according to its composition.Inorganic silica gel is a kind of high activity adsorption material, which is usually used to react with sodium silicate and sulfuric acid, and it is produced by a series of post-processing processes such as aging and acid bubble.Silica gel is a amorphous substance whose chemical molecular formula is mSiO2.NH2O.Insoluble in water and any solvent, non-toxic and tasteless, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.Different types of silica gel have different microporous structures due to different manufacturing methods.Chemical components and physical structure of the silica gel, determines it has many other features of similar materials difficult to replace, high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc.Organic silica gel is a kind of organic silicon compounds, refers to contain Si - C keys, and at least one organic group is directly linked to the silicon atoms compounds, habits are often those with oxygen, sulfur, nitrogen, etc organic base connected to the silicon atoms compounds as organic silicon compounds.Among them, polysiloxane, composed of silicon oxygen bond (-si-o-si -), is the largest group of organosilicon compounds, the most studied and the most widely used, accounting for over 90% of the total dosage.Extruded silica gel is more common, such as the sealing ring on the rice cooker of household, called the electric rice cooker silicone sealing ring.The moulded silica gel is a bit more complicated, with irregular shape, including silica gel bowl, silica gel ice cube, silica gel cake mould and so on.
