Nano mineral crystal activated carbon is made of activated carbon with rich porous mineral adsorbents (sepiolite, diatomite, bentonite, and attapulgite), manufactured by patented technology.
The product is in shape of tiny black mineral crystal balls in 2-3 mm diameter. Studying its microstructure, one can find that the mineral crystal has unique regular structure, containing large amount of nano-scale pores in size of 2.7Å-9.8Å. The micropores in such scale have strong adsorption ability for gas compounds of Amy grade and nanometer molecules. Especially, because the surface of the micropores is polar, it shows strong attraction to polar molecules. Thus the micropores can selectively adsorb polar molecules such as benzene, xylene, formaldehyde, carbon monoxide, sulfur dioxide, ammonia and other toxic and harmful substances. Furthermore, at temperature around 40-50 ℃(104-122 ℉), the mineral crystal can be simply desorption and regeneration.
As a summary, for its excellent adsorption ability to polar molecules, its large surface area due to the nano size of micropores, and its relatively low desorption temperature, the nano mineral crystal active carbon can be made into a sort of effective, reusable, and environmental benign air purify material.
