Exaggerate the capacity of activated Carbon carving

Because the surface area of small, the decision of the small capacity, according to a high surface area 1500-2000 sq ft / grams, 50 grams per square foot of the amount, if formaldehyde and other harmful gases released faster, up to 5-8 months, the Thai activated carbon The capacity to exaggerate the use of 3-10 years is to deceive consumers. Activated carbon absorption of harmful gas as the principle of the same absorbent sponge, sponge the capacity of some, the greater leakage, the sponge saturated absorption capacity, activated carbon is a carbon-containing materials from the appearance of black, internal pore structure developed, Large surface area, the absorption ability of a class of carbon-ceramic materials. Because there are a large number of activated carbon in the porous naked eye can not see a grain of rice - the size of activated carbon particles in a porous, a large surface area equivalent to the size of the living room walls, and the large number of activated carbon surface molecules can produce a powerful gravitational force, Adsorption medium of the impurities and heavier elements, such as chlorine, benzene, ammonia, and so on, so at home, placing a certain amount of activated carbon to effectively "capture" all kinds of harmful toxic gases and impurities. But as the Billiard Checkers board, activated carbon to the absorption of harmful gases equivalent to one piece of Qianjin chessboard box. Activated carbon adsorption capacity will be filled with the porous gradually weaken and eventually reach saturation absorption. Therefore, if there are constantly new sources of the use of activated carbon to purify the air, for a period of time to time for activated carbon. Therefore such an unlimited number of absorption unrealistic.
