Coconut shell activated carbon is treated by a special treatment of activated carbon, not only has a good physical adsorption, but also has a catalytic decomposition of pollutants, will not form a secondary pollution answer: common activated carbon is a special firing process carbonization of a porous material, a very rich pore structure and great surface area, can absorb odor and harmful gases, but can not be decomposed (with the photocatalytic than there is a lack of time or to replace the function of no light catalytic so comprehensive) expert experience shows that: the room floor full of activated carbon can adjust the humidity, purify the air to help the floor cut off moisture, so that the floor from the threat of moisture deformation.
