The iodine value is a difference in the performance of activated carbon. The iodine value of the shell, bamboo charcoal and coal is several hundred. The iodine value of the activated carbon raw material is 800, 850, 900, 950, 1000, 1100 mg/g, etc. Different! Cost price is also different! Activated carbon with the same iodine value only has the best effect of coconut shell.
Only the pore structure can be made on activated carbon as much as possible. The more pores, the more loose the activated carbon and the lighter the relative density. Therefore, the good activated carbon will be lighter in hand, and the activated carbon with good performance in the same weight package. It will be much larger than inferior activated carbon.
A small amount of activated carbon is put into the water. Due to the penetration of water, the water will gradually immerse into the pore structure of the activated carbon, forcing the air in the pores to be discharged, thereby generating a series of extremely fine bubbles, pulling out a small bubble line in the water. At the same time, it will make a sound of bubbles, which is very interesting. The more intense this phenomenon occurs, the longer the duration, the better the adsorption of activated carbon.
