Clay
Desiccant
Clay desiccant is made of Attapulgite. Yuanying clay desiccant has great specific surface
area, high adsorption capacity, high stability at high temperatures and in salt
water
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.
Yuanying
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.
