Activated carbon filter cartridge

Product Description

The production process of activated carbon can be divided into two procedures: carbonization and activation. Carbonization is a process in which the material is turned into porous carbon structure through pyrolysis under conditions of lacking oxygen and between the temperatures ******0℃. During carbonization , most of non-carbon elements will be eliminated as volatile gas by　decomposition procedure of material. Such carbonization product (carbon atom combination) – the piece structure of polycyclic aromatic hydrocarbons, PAHs, due to it’s difform, the chink will become the pore structure in activation procedure. Theory: The activated carbon is oxidize the coconut shells, charcoal, wood or coal under high temperatures. Make them become the particles with many small pores inside. The hole on the surface is wider and become narrower inner, and finally sealed itself ***** width of pore is from several angstrom to tens of thousands of angstrom. For 1 gram of Activated carbon, the measure of area for pore is about 1, **0 square meter . The activated carbon is using pores to absorb chlorine and organic matter. Regarding the“Adsorption”and“absorption”, there is one letter different in spelling, but their effect is total different. Absorption is to adhere impurity to the surface of the activated carbon, two objects will not turn into one and bring any chemical reaction. Thus, after using several times, the activated carbon will lose adsorption effectiveness and can’t be used anymore then need to make a replacement.
