High-quality humidity absorber refill mainly refers to calcium chloride desiccant. Its moisture absorption effect is more than ten times that of general desiccant. It can absorb about 300% of its own weight and can effectively absorb moisture from gas or liquid. of solid matter. Super hygroscopic desiccant can be classified according to pore size, particle shape, chemical composition, surface polarity, etc. The packaging material of calcium chloride is generally fixed, the inner layer of PET film + unidirectional breathable cloth or unidirectional breathable DuPont paper, outer layer. The layer is made of one-way breathable cloth, which can well prevent the leakage of calcium chloride desiccant and other phenomena.

The main raw material of high-quality humidity absorber refill, calcium chloride, is made of high-quality calcium carbonate and hydrochloric acid as raw materials, and is refined through reaction synthesis, filtration, evaporation concentration, drying and other processes. Calcium chloride desiccant has the functions of adsorption, active static dehumidification and odor removal. It is packaged by multi-layer materials, which is safe and firm, and completely eliminates the possibility of leakage.
 
High-quality humidity absorber refill generally has the following characteristics:
1. Large surface, suitable pore structure and surface structure;
2. It has a strong adsorption effect on water;
3. Generally, it does not react chemically with water and medium;
4. It is easy to make and can be regenerated;
5. Strong adaptability to the environment.
