In progress Activated carbon Before processing, people should first choose suitable materials. Ordinary wood, as well as hard fruit wood shells, can be used as raw materials. In the process of processing, the first thing to do is to dry and dehydrate these raw materials. This process is relatively simple and can be completed under ordinary high temperature. After completing this step, the next step is to carbonize it.

In the temperature environment up to several hundred degrees, most impurities in the raw materials are gradually decomposed to generate other volatile substances, such as methane and ethylene. When heated to a certain time, the easily decomposed substances in the material gradually evaporate, and finally the internal pore structure is formed. At this time, activated carbon We can basically see the effect of processing. The next step is to carry out further activation measures. The so-called activation actually refers to a process of re decomposition by reheating and with the help of oxidant.

Activated carbon commonly used nowadays Activating oxidant, including carbon dioxide or water vapor. In addition, air can also be used when the temperature is not too high. Through activation, a large number of holes originally appeared in this material can be connected with each other at this time. In this way, there are a large number of connected holes inside, which can let other substances pass through and play the role of absorbing impurities. After activation, there is a final procedure in the whole processing process, which is to clean and process it so that it can be directly used in real life.
