1. Raw Materials of Mineral Desiccan
1) Characteristics
- Composed of several natual minerals, safe, non-toxic, and friendly to environment
- Absolute adsorption rate is up to 50% of its weight (25℃,RH=100%), whereas that of the common silicon desiccant is only about 30%
- Uniform granule, non-dusting, suitable to packing machine for silica gel
2) Quality Standard
- Moisture adsorption rate (25℃,RH=80%): >40%
- Loss on drying: <2.5%
- Bulk density: 0.75-0.95 g/ml
- Period of validity: 18 months
