What is Nano Mineral Crystal Activated Carbon?
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 formaldehyde, carbon monoxide, sulfur dioxide, ammonia and other toxic and harmful substances including benzene and xylene. 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 activated carbon can be made into a sort of effective, reusable, and environmental benign air purify material.
Comparing with traditional air purification products, such as activated charcoal, bamboo charcoal, what’s the advantage of using nano mineral crystal activated carbon?
The traditional activated charcoal needs very hight temperature for desorption (500–900 °C, or 932–1,652 °F) . In normal users’ condition, it’s impossible to regenerate the activated charcoal by desorption. Exposing the product under the sunshine can only vaporize the water molecules that were trapped inside the micropores structure: which can only improve the adsorption in a very limited way. As a result, the life span for activated charcoal products is much shorter, usually 5-8 months. On the other hand, since the nano mineral crystal activated carbon has a very low temperature for desorption (40-50℃ or 104-122 ℉), exposing the product under summer’s sunshine can easily make desorption happen, and rejuvenate it back to fresh.
What is polar molecule?
A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O), carbon monoxide (CO), Ammonia (NH3), and many toxic substances are polar, such as formaldehyde and sulfur dioxide.
What is adsorption and desorption?
Adsorption is a surface-based process, it is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. Desorption is a phenomenon whereby a substance is released from or through a surface, which is the opposite of sorption.
