What are the main ingredients of silica gel treating agent
09 Aug 2019
Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.
It is a kind of highly active adsorption material, which is processed into granular or beaded form by purification of natural minerals.Silica is a spongy structure with numerous pores.Holes can absorb water, which is why silica is widely used in silica gel treatment agent production.It is chemically stable and does not burn.Silica gel is a kind of amorphous silica, should control the workshop dust content is not more than 10 mg/m3 silica gel was mostly carbon dioxide, the main composition of silica gel treatment agent is silica, environmental non-toxic inorganic silica gel is a highly active adsorption organic non-toxic material, usually is to use sodium silicate and sulfuric acid reaction, and the aging, acid soak and a series of post-processing process and system.Silica gel is an amorphous material whose chemical formula is mSiO2.NH2O.Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, except strong alkali, hydrofluoric acid and no reaction with any substances.Different types of silica gel form different microporous structures due to different manufacturing methods.The chemical composition and physical structure of silica gel agent determine that it has many other similar materials difficult to replace the characteristics of high adsorption, good thermal stability, chemical properties.
