Speaking of desiccants, there are many kinds on the market, and different products use different products. So how to choose?
Commonly used foods include silica gel, lime, mineral, montmorillonite, etc. most of the products in the market are silica gel. Silica gel is the only desiccant that can directly contact drugs and food through FDA certification.
There are silica gel and columnar fibers used in medicine. Drug manufacturers must have dust-free workshops and drug packaging certificates.
Electrical and electronic use: silica gel, montmorillonite, mineral, biochemical.
The moisture-proof effect of desiccant should be considered from its own performance and use environment.
When selecting desiccant for electronic products, consider:
1. Choose non corrosive.
2. Choose the one that is not easy to produce dust.
Clothes, shoes and hats are made of silica gel, montmorillonite, calcium chloride, fiber and biochemical. It is mainly used for the packaging of shoes, hats, clothing, leather, bags and other products to absorb moisture to prevent products from mildew due to high humidity.
Containers and storage: calcium chloride, biochemical desiccant, drying rod, etc. Among them, the moisture absorption rate of biochemical desiccant can reach 300%., It is mainly used for Marine Containers to adsorb containers during marine transportation or storage. Due to the large changes of marine humidity climate and temperature difference between day and night, the water vapor in the container will condense into water droplets to form "container rain". It is commonly used in the container to reduce the moisture content of air and prevent the formation of container rain.
