Many people are buying Activated carbon There will always be a trouble in how to identify the quality of activated carbon. Activated carbon is widely used in our life. If we buy poor quality activated carbon, it is likely to cause the opposite effect. Let's see how to identify it
1. The first is to observe the surface
The surface of regenerated activated carbon is gray and the cross section of particles is not bright. There will be many small cracks. The edges and corners are not clear, and the edges and corners are obviously smooth, which is mainly caused by the friction between particles during the previous use and regeneration. This is very easy to observe.
The adsorption capacity of activated carbon is proportional to the pore size. The higher the adsorption capacity of activated carbon is, the larger the pore size is. However, the more activated carbon, the lighter the density. The better the quality of activated carbon, the lighter the handle will be. Therefore, under the condition of the same weight of packaging, the activated carbon will be much larger than the false activated carbon.
3. Look at the particle size
The smaller the particle size of activated carbon, the larger the area of natural contact with air, but its adsorption effect will also be better. However, the particles are small, and the loss during crushing is also large. Therefore, in order to reduce costs, many manufacturers use large particles of activated carbon. The performance of activated carbon with particles more than 2mm is already very poor.
I believe you know something. In the next issue, we will continue to learn how to identify the quality of activated carbon.
