Bentonite clay Introduction
Advantages :
Our product boasts pure nature raw material---bentonite, Its raw material is high –quality montmorillonite in Inrer Monglia. Montmorillonite is higher than 95% in purity. which is environment-friendly without poison and smell,It has no side effect to body. It has superior effect especial at room temperature and in average humidity. Our product has the function of active particle absorption, static dehumidification and odor elimination. It is the substitute for Silicagel desiccant.
Characteristics:
It has the advantages of low price, quick absorption speed, low production cost, etc. Compared to other kinds of dry desiccant sold in market, it features quick absorption speed and strong absorption capacity without toxicity, smell, erosion or environment pollution, without any harm to people. It is particularly suitable for food packing.
Application:
It is widely used for sealed storage of products in dry air that cannot be sealed by oil or gas, such as optical equipment electronic products, medical products, health care products food packing, military products and civil products.
Molecular formula: Al2O3·4SiO2·nH2O

Use Method:
The use method lies on such elements as package material, airproof extent, pack dimension, surface area of pack, sealed years and etc.
- If the package uses water-proof, moisture-proof material, the desiccent amount can be caculated out according to the following list.

Notices:
The product should be placed in the suitable part of container to ensure the demoisture effect in complete room airproofed. Add the desiccent amount to prevent loss caused by water coagulation when protecting valuable material.
Reuse Mothod:
To improve the activity and reuse the Bentonite desiccent after using for a certain period time, drying it in the constant temperature of 140 °C in oven to 1% moisture content..
