   Activated carbon is a high amount of carbon-containing material such as coal, shell, oil residue and other raw materials firing from the carbide, the professional activation treatment, the formation of a rich pores to reach certain specific surface area and adsorption capacity requirements, which is activated carbon. Activated carbon can be divided into decolorizing charcoal, activated carbon water purification, air purification activated carbon, activated carbon and other heavy metal recycling. Wide range of uses, is the quality of the adsorbent material. Carbon air purification is an activated carbon. Quality activated carbon is a special treatment for special purifying polluted air, so called carbon air purification. Only hardness, high strength, porosity of microporous activated carbon to carbon as an air purifier. Husk charcoal coal can do air purification charcoal, charcoal husk which is best for the following reasons: Not all can do the activated carbon air purification. Activated carbon pore by pore size can be divided into three categories. Big hole: the radius of 100 - 2000 nm. Transition holes: radius 2 - 100nm. Microporous: radius 2nm or less. Activated carbon made from different materials having different pore sizes. Nutshell activated carbon from the system with the smallest pore radius, such a small purge gas rich microporous most suitable small molecules. Because clean air requirements of its large specific surface area, pore size slightly larger than the size of the gas is adsorbed molecules. Wood activated carbon generally has a maximum pore radius, they are used to adsorb larger molecules, and almost exclusively in the liquid phase. Coal activated carbon pore size in between. Activated carbon from coal has more transition pore and larger average pore size, it can effectively remove organic molecules in water. General activated carbon used in water treatment, which is not necessarily the specific surface area is too large, it should have more transition pore and larger average pore size.
Purpose: to formaldehyde odor.
