Introduction

Attapulgite also called Palygorskite, mineralogical classification belongs to family of sepiolite, is a kind of layer-chain structure of hydrous rich magnesium aluminum silicate clay mineral. Attapulgite has great specific surface area and certain ion exchange performance, most of positive ions, water molecules, a certain size of organic molecules can be adsorbed into its pore canal. Attapulgite has stable electrochemical performance, hard to be electrolytic flocculation, high stability at high temperatures and in salt water. Widely used for desiccant, anti-blushing agent, adsorbent, catalyst support, bacteriostat support.

Attapulgite clay desiccant working temperature should be under 50℃, if temperature over 50℃, water release is bigger than water uptake. But clay desiccant is very cheap, so it becomes one of main mineral desiccant in the world.

Clay Desiccant has no deformation and no fever after moisture absorption, very few water-soluble substances, no corrosion to metal. 

It has the following characteristics:

1. Natural, non-toxic, tasteless, pollution-free, 100% natural degradation

2. Super hygroscopic capacity, stronger than silica gel. No reverse osmosis after moisture adsorption, can guarantee the desiccant packages is always in dry state

3. Selective adsorption of polar molecules, its adsorption capacity in turn is water > alcohol > aldehyde > ketone > alkene > neutral lipid > aromatic hydrocarbon > cyclanes > alkanes

4. Strong decolorization capacity. 75-85% Attapulgite decoloring capacity 110-130, is higher than active floridin

5. Has a strong sterilization, deodorant, detoxification, insecticide capability, can be used for protective device for adsorbing gas

6. Formed by the natural attapulgite, conform to the advanced industrial countries of the "4R" and "1D" standard

Clay desiccant is widely used in electronics, electrical appliances, food, clothing, electrical and mechanical equipment, military, marine transportation and other industries.

Application

It is used in products which can’t use oil seal or gaseous phase to seal up for keeping, such as optics instrument, electron products, leechdom health care, food packing, communications equipment, precision mechanism, semiconductor, war industry product and civilian industry product. It is used in above industry for dampproof and dehumidifying.
