1. The adsorption capacity of activated carbon with the same weight and volume is stronger
In order to improve the adsorption performance of activated carbon, only as much as possible to create pore structure on the activated carbon.activated carbon manufacturer south africa The more pores, the looser the activated carbon, the lighter the relative density. Therefore, a good activated carbon handle will be lighter. In the case of the same weight packaging, the volume of the activated carbon with good performance will be much larger than that of the poor quality activated carbon.
2. The higher the iodine value is, the better carbon is
Activated carbon purification of gas depends on the adsorption capacity, here is an important index of adsorption capacity - iodine value, the higher the iodine value, the stronger the adsorption capacity. Now stir fried coconut shell carbon is relatively hot, but some of the activated or unqualified coconut shell carbon iodine value may not reach 500. The iodine value of Haixin's high-grade fruit shell for air purification can reach 800-1200, and its adsorption capacity can reach the effect of first-class brand air purification carbon. In addition to some well-known brands with certified effect, we should ask the seller to present the iodine value test report when purchasing most other air purification carbon.
3. The permeability of carbon package is very important
Put the activated carbon bag at the mouth to blow, if the gas can easily pass through the carbon package, it shows that the air permeability of the carbon package is good. If the carbon bag can not be blown, the air is difficult to pass through, and it is difficult to make a great contribution to the carbon package. As a passive adsorption product, the air must be able to penetrate into the deep layer of the carbon package freely, so that the carbon package can play a good role in air purification and adsorption. Theoretically speaking, tearing the activated carbon bag and putting the carbon directly into the tray may be the best way to pass air, of course, this way has a certain impact on environmental sanitation.
