Activated carbon is a kind of microcrystalline carbon material that is mainly made of carbon-containing materials and has a black appearance, developed internal pore structure, large specific surface area, and strong adsorption capacity. powdered activated carbon manufacturer There are a large number of micropores invisible to the naked eye in the activated carbon material. The surface area of the micropores in 1 gram of activated carbon material can be as high as 800-3000 square meters, which is even higher for special purposes.
In other words, in an activated carbon particle the size of a rice grain, the inner surface area of the micropores may be equivalent to the size of a living room area. It is these highly developed, human capillary-like pore structures that make activated carbon possess excellent adsorption properties.
The key factors affecting the service life of activated carbon for air purification are the total amount of harmful substances in the environment and the frequency of desorption. The quality of activated carbon adsorbing harmful gases can approach or even reach its own quality. In the air of ordinary households, the quality of harmful gases is far less than the amount of activated carbon used. Therefore, as long as the activated carbon is often placed in the sun, it can be long-term use.www.granular-activated-carbon.com
