Specification :

Air purification activated carbon uses the materials with higher carbon as raw material such as coal nut shell, wood, bone, petroleum residue and etc. The product is produced through professional activating treatment to form abundant micropore, which makes the specific surface area and adsorption capacity achieve certain requirements. The air purification activated carbon production usually divides into two processes, one is carbonization, the other is activation. Activated carbon includes decolorization activated carbon, water purification activated carbon, air purification activated carbon, heavy metal recovery activated carbon and so on. Air purification activated carbon has widely usages, and is the high quality adsorbing material.
Air purification activated carbon is one kind of activated carbon, and specially used for purification of polluted air. The air purification activated carbon must have the characteristics of good hardness, high strength, micropore structure. The nut shell carbon, coal carbon can be used as the raw materials of air purification. The nut shell carbon has the best effect.
The process of air purification activated carbon production
1. Carbonization
The nut shell carbonization furnace is used to through pre-heat, then go into the carbonized process with high temperature heating from 450 to 500, and provide air combustion-support without any other fuel. Then the process goes into cooling coil section. The carbonized exhaust won’ t pollute the air. The structure of the carbon is graphite shape hexagonal microcrystalline.
2. Activation
The activation of air purification activated carbon uses air activation method. Usually the activated carbon activation furnace uses the steam and the activation process produced flue-gas as activator to finish the activation process together. The activation needs the high temperature from 850 to 950, about also needs 10 atmospheric pressure.
Air purification activated carbon adsorption effect principle
Air purification activated carbon is black and one kind of microcrystalline carbon materials with advanced internal pore structure, large specific surface area and strong air adsorption ability. Air purification activated carbon material has a plenty of invisible micropore, the specific surface area of micropore of 1g activated carbon material unfold can achieve 800— 3000 square meter, and the specially usage activated carbon can achieve higher. It means that the internal surface area of micropore of a rice grain-size air purification activated carbon particle may equivalent to a sitting room area. Because of the highly development and just as human blood capillary pore structure, the activated carbon owns excellent adsorption capacity.
