¡ôAbsorption and Purification
Vermiculite has superior adsorption performance and ion exchange ability. It's usually used as catalyst such as moisture absorbent material, filter material. It can absorb and resolve dust in the air, fine particle, virus, harmful substance, peculiar smell and to purify the air.
The vermiculite is a 38 layer surface structure silicate material, with two-dimensional layered structure and provide a large surface area(500-800 m2 per gram) for the molecules between laminated layers. And the vermiculite can absorb inorganic ions, organic ions and polar molecule especially efficient for water and polar molecule absorption because of the surface of vermiculite is electrification.
