Activated carbon air purifier outdoor air purifier long attracted attention, the past 30 years more emphasis on indoor air quality. Since the discovery of some office workers suffering from "office syndrome" since the people on indoor air pollution on human health hazards are more concerns. According to studies, indoor air pollution are: building materials, such as brick, wallpaper, paint; gas, coal and other combustion; fried, smoked cooking class; smokers smoke; some cosmetics. Indoor pollutants that comes out of a lot of species, many of quantity; US EPA, said the concentration of volatile organic compounds in indoor often several times higher than outdoor, studies have shown that the air conditioning system often due to poor ventilation, polluted indoor air. 19. Amendment 89 Canadian indoor air quality standards, some scholars believe that the air quality standards in 1987 World Health Organization provisions applicable to the interior. Rationale for the rule of air pollution can be used activated carbon adsorption, catalysis, combustion, condensation sugar with activated carbon, which use activated carbon adsorption or catalytic method is very common. Exhaust gas having a high surface area porous carbon package supplier of activated carbon contacting, of pollutants are adsorbed, so that the gas mixture is separated, sky purification. Extract gold using activated carbon coconut shell activated carbon, coconut shell as raw material quality used in Southeast Asia, and processed by the carbonization temperature activation and pretreatment refined. Products have developed pore structure, large specific surface area, high abrasion resistance, absorption speed, large adsorption capacity, easy desorption, repeated use of renewable notable features, widely used in CIP and heap leach gold extraction process. The gold using a special process using activated carbon, granular activated carbon made of high-strength plastic shell activated carbon in Dongguan, in addition to almost all the particles in needle-shaped, pointed shape, angular and so easy to wear parts. Particle shape full, uniform carbon, greatly improving the abrasion resistance of the product, into the plant without the need for pre-ground, can be used directly after water.
