1. Silica gel desiccant:

 

Silica gel desiccant is a colorless or yellowish transparent or translucent silicon dioxide crystal (also known as silica gel), is a non-chemical reaction crystals, the crystal's interior is a very fine pore network structure, these capillaries can absorb water and retain water through its physical attraction, aviation components, computer devices, electronic products, leather. Pharmaceutical, food and other industries. Even if the desiccant is completely immersed in water, it will not soften or liquefy. It is non-toxic, tasteless, non-corrosive and non-polluting, so it can be in direct contact with any object.

 

Active mineral desiccants:

 

Active mineral desiccant is refined from pure natural raw material minerals and active moisture absorbent. It is environmentally friendly, non-toxic and tasteless, and harmless to human body. The product has good adsorption performance at room temperature and general humidity, with adsorption activity, static dehumidification and odor removal.

 

Scope of application:

 

It is widely used in products that can not be sealed by oil or gas phase, such as optical instruments, electronic products, medical care, food packaging and dry air storage of military and civil products.

 

3. Quick lime desiccants:

 

Quick lime desiccant is a kind of white calcium oxide solid particles produced by high temperature calcination of natural calcium carbonate ores. It is a kind of desiccant hygroscopic material that meets the requirements of environmental protection. It does not contain harmful substances and heavy metals restricted by European and American countries. Desiccant hygroscopic materials consume moisture in the packaging content space through the chemical reaction between calcium oxide and water, thus playing the role of moisture absorption. The process of moisture absorption is a chemical reaction process, which is irreversible.

 

Fourth, montmorillonite desiccant:

 

The montmorillonite desiccant is made of natural montmorillonite ore, which is heated at high temperature, carbonized organic matter, expanded montmorillonite ore body, steam treatment, drying, activation, crushing and screening. It is a natural, non-toxic, pollution-free, degradable, healthy and environmental friendly desiccant. It does not contain any additives, corrosive substances or chlorides. The product quality standard conforms to the Chinese military standard GJB2714-96 and the American military standard MIL-D-3464E.
