Raw material: attapulgite clay. Chemical name: silicate clay Molecular formula: Mg5Si8O20(HO)2(OH2)4 .4H2O Description: there are multiple channels inside attapulgite clay and specific surface area is large, more than 350 m2/g. Majority of cation, water molecule and organic molecule with certain size can be directly absorbed into channels; its water absorption can be over 150%. |

Characteristics of product Green environmental protection: adopt pure natural mineral material, without pollution during processes of production and use. Be able to degrade absolutely. Unwrapped package can be disposed as ordinary waste materials. CaCl2 content: far lower than that of other mineral drying agents existed in current market. Preeminent moisture absorption: moisture absorption capacity is up to 70%. Be able to be used repeatedly: absorbing moisture and then being dried, the product can be used again, so as to reduce the cost. High-quality before-sale, middle-sale and after-sale service: entrust professional distribution companies to sell, and design optimization according to usable environments of object products.
