The working principle of silica gel desiccant
The silica gel desiccant is mainly obtained by reacting with sodium silicate and sulfuric acid, and through a series of post-treatment processes such as aging and acid bubble, etc. It is insoluble in water and any solvent, tasteless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Both its chemical and physical properties give silica gel good moisture absorption ability. As a desiccant, the drying principle of silica gel relies on adsorption to remove the water molecules in moist substances, that is, through the mutual attraction between the plasmas on the solid surface and the water molecules in various gases and liquids, etc. and adsorbs them on the surface of solid substances, most of these substances have many pores and have a huge surface
Silica gel itself is a neutral substance and will not react with any other substances except for reacting with strong alkali and strong acid under certain conditions. It is a kind of desiccant that can be used in direct contact with medicine and food. The physical desiccant with adsorption effect can be used as desiccant, except for silica gel, there are also activated carbon, activated alumina and so on.
