The main ingredient of silica gel desiccant is silicon dioxidewith a microporous structure, which has strong moisture absorption ability, non-toxic, tasteless, odorless, chemically stable, and is a highly active adsorption material. It is usually prepared by the reaction of sodium silicate and sulfuric acid, and after a series of production processes such as aging and acid foaming. Silica gel desiccant is an amorphous substance, its appearance is transparent or translucent, mostly bead-like or irregular granules, and its chemical formula is mSiO₂·nH2O. Because silica gel desiccant has excellent moisture-proof and adsorption performance, it is widely used in food, medicine, bags, shoes and hats, instruments, equipment, textiles and other industries. In storage and transportation, silica gel desiccant can play a role in controlling the relative humidity of the environment, reduce and slow down the moisture, mildew and rust.

Avoid direct contact with silica gel desiccant for a long time to avoid discomfort or allergic reaction to the skin;
Avoid inhaling silica gel dust during operation, if you accidentally inhale a large amount of dust, you should leave the scene immediately and seek medical attention in time;
When storing silica gel, it should be placed in a dry and ventilated place to avoid contact with acids and alkalis.
Silica gel desiccant has strong moisture absorption ability, so it should be stored in a dry place, sealed and preserved, and isolated from air. There should be a shelf between the package and the ground, and it should be avoided from rain, moisture and sun during transportation.
