Silica gel desiccant is a kind of highly active adsorption material, which is usually prepared by reaction of sodium silicate with sulfuric acid, aging and acid bubble. Silica gel is an amorphous substance with the chemical formula of msio2.nh2o. It is insoluble in water and any solvent, non-toxic, tasteless, stable chemical properties, and does not react with any substance except strong base and hydrofluoric acid.

Drugs, machinery, optics and electronics, precision instruments, meters, seeds, processed food, tea, various chemical fiber textiles, leather shoes, leather shoes, sports shoes, cultural relics archives, cameras, arts and crafts, etc., are widely used. The details are as follows

1. The silica gel desiccant can be used for the moisture-proof of bottled medicine and food. Ensure the drying of the contents and articles, and prevent the growth of various miscellaneous molds.

2. Silica gel desiccant can be used as general packaging desiccant. Such as bags, clothing, shoes and hats, leather, etc., to prevent the goods from being affected by moisture during storage or transportation.

3. Silica gel desiccant can be conveniently placed in electronic products, instruments, household appliances, mechanical equipment and other products to prevent the product quality from being affected by moisture.

4. Silica gel desiccant can be placed in transport container to prevent container rain.

5. The most suitable hygroscopic environment of silica gel desiccant is room temperature (20 ~ 32 ℃) and high temperature (60 ~ 90 ℃). It can reduce the relative humidity of the environment to about 40%. Therefore, the application range of silica gel desiccant is very wide.
