Abstract

The invention discloses a high-moisture-absorptivity mineral dryer and a preparation method thereof. The dryer is prepared from, by weight, 22-28 parts of halloysite, 30-40 parts of bauxite, 17-29 parts of turquoise, 16-24 parts of dolomite, 20-25 parts of cement slag, 10-15 parts of rock wool powder, 8-12 parts of 4A molecular sieve, 6-11 parts of aluminum potassium sulfate, 5-10 parts of quicklime, 4-8 parts of calcium chloride and 98-114 parts of modifier. The dryer prepared by the method is high in moisture absorptivity which is more than 1.5 times that of conventional dryers, and is large in moisture absorbing quantity, and total moisture absorbing quantity can reach higher than 2 times of own weight; moisture absorbing performance can be maintained stable in various temperature environments, and the dryer is high in moisture absorbing speed, suitable for being used in various places and wide in market prospect.

Description

technical field [0001] The invention relates to a molecular sieve and a preparation method thereof, in particular to a mineral desiccant with a high moisture absorption rate and a preparation method thereof. Background technique [0002] Mineral desiccant is refined from pure natural raw material minerals and a small amount of additives. It is environmentally friendly, non-toxic and tasteless. Mineral desiccants have the functions of adsorption activity, static dehumidification and odor removal, and are widely used in gas drying, food storage, liquid drying, automobile brakes, pharmaceuticals, clothing, military industry, electronics and other fields. [0003] In recent years, with the continuous improvement of living standards, the performance requirements for indoor mineral desiccants are getting higher and higher. At present, the mineral desiccants used for indoor use in the market have the disadvantage of low hygroscopicity and cannot perform good drying. The effect can...
