Method for preparing hygroscopic agent prepared by adsorbing koto sulfate on diatomaceous earth filler and zeolite particle

摘要

The present invention relates to a manufacturing method of a moisture absorbent prepared by adsorbing high sulfuric acid (MgSO ₄ ) on a diatomaceous earth adsorbent and a zeolite particle, and in particular, has excellent hygroscopicity, low manufacturing cost, and no chlorine group (Cl). It is intended to be used not only for parts but also for food and medicine.;In order to achieve the above object, the present invention grinds the diatomaceous earth and the zeolite to a size of about 0.5 to 10 mm, granulates and calcinates it, and activates the granules by mixing the activated granules at an appropriate ratio to obtain a mixed granule. It is prepared by adsorbing Goto sulfate (MgSO ₄ ) to dry cooling.
