Desiccants refer to substances that can remove moisture from wet substances. They are often divided into two categories: physical desiccants, such as silica gel and activated alumina, which are dried by physically adsorbing water; chemical desiccants, such as CaSO4.2H2O and CaCl2, etc., Dry by combining with water to form hydrate. Special desiccant features: high sanitation requirements, packaging materials have passed the US FDA demonstration, the product is compact, efficient, exquisite and environmentally friendly, with good compatibility and chemical stability. Let's follow the editor of Shenzhen Mingwei Industry to understand how the desiccant is installed and used in different environments?

Desiccants are classified according to the application environment, generally in three situations:
1. Small environment: The desiccant is directly placed in a bottle, can or other airtight pouch to keep the items in the small environment dry.
2. Mid-environment: The desiccant is used directly in the packaging carton (or packaging barrel, bag) to avoid moisture in the packaging.
3. Large environment: The desiccant is used directly in similar warehouses and containers to achieve the purpose of controlling the humidity of the large environment.
