With the increase of the adsorption capacity, the consumption cost of activated carbon is higher, and it increases geometrically. The coconut shell carbon (300-500 square grams / gram) is not activated. It is only 2.5 yuan per kilogram, which is the motive for selling low adsorption activated carbon as high adsorption activated carbon on the market. Look at the activated carbon with smaller particle size particles.
The larger the area of air contact, the larger the surface area, the better the adsorption effect, but the smaller the particles, the greater the loss during the crushing and manufacturing process, and the more dust, so many manufacturers use large particle activated carbon in order to reduce costs. Of course not good, the performance of activated carbon with particles exceeding 2mm is very poor.
The primary criterion for the use of activated carbon in dust is that it cannot be dirty. Consumer activated carbon must be disposed of after stopping, that is, to stop the crushed coconut shells to remove dust, otherwise the dust will be too much, and the cleanliness will be very poor. It will be very dirty on the surface. If it is inhaled, it will be harmful to the human body. In addition, the surrounding articles will be contaminated. In order to reduce the cost, the low-quality activated carbon on the market has not been disposed of after the activated carbon has been stopped. The dust is very large. The hand model will be very dirty, and it will stain the surrounding objects when used.
