What is activated carbon?

      Activated carbon, but from organic raw materials (such as fruit shells, coal, wood, these small cute) into the raw materials have to be locked in a small room without air, and then give them heat to heat, so that their "impurities on the small partners" are running away, this process we call it carbonization. And then let these carbonized partners and gas fusion, so that their surfaces become pitted, just like the surface of the moon (of course, is microscopic), this process is activation. This process is called activation. Thus, activated carbon is born!

      Activated charcoal is made from wood, coal and petroleum coke, members of the "big family", through a series of reactions. They have a lot of pores, a large surface area, and a lot of magical chemical groups on the surface, so the adsorption capacity is super strong, usually in powder or granular form, like a small magical powder or magical beans, can adsorb a lot of things!

Preparation of ah, you have to first solid carbonaceous material (coal, wood, hard fruit shells, kernels, resin, and so on) in an oxygen-free environment heated to 600 ~ 900 ℃, so that they have "impurities" are run off. Then, air, carbon dioxide, water vapor or a mixture of gases to give them an "oxidation activation party", so that they become more active, more pore space, stronger adsorption capacity! Depending on the activation temperature, activated carbon can also be divided into L-carbon and H-carbon, which are "delicate" and must be cooled in an inert atmosphere, otherwise they will become L-carbon. The adsorption capacity of activated carbon is affected by many factors, such as the nature and concentration of the activated gas, the activation temperature, the degree of activation, and the composition and content of inorganic substances in the activated carbon. Nevertheless, the most important factors are the nature of the activation gas and the activation temperature.

      As Activated carbon adsorption manufacturers, there are activated carbon for wastewater treatment, activated carbon from rice husk and so on, welcome to inquire.
