MOISTURE SORBENT AND PROCESS FOR ITS MANUFACTURE

摘要

The damp-proof chemical has a better damp sucking capability than silicagel and can be used for foods and medicines. And the radii of particles are small and even. Production cost of the chemical can be reduced greatly because the chemical is made from natural diatomaceous earth. The producing method comprises the steps: obtaining natural distomaceous earth having 0.1-3 mm radii as a core in 5-80% weight ratio; making damp keeping prime material from zeolite in 5-50% weight ratio; making mucus from bentonite under 200 mesh in 5-50% weight ratio; mixing these materials with a smell eliminating element to produce intermediate powder; combining the powder with a chloride aqueous solution to dry at 150-200 deg.C.
