Because coconut shell activated carbon is much more expensive than coal-based activated carbon, and the finished activated carbon material is generally not easily recognized by the general public. In the market, unscrupulous sellers often use the weakness of consumers' unrecognizable materials and sell them with coal-based activated carbon fake coconut shell activated carbon, which is more serious in civil or industrial fields.
Here are a few ways to easily distinguish between them
1. Coconut shell activated carbon belongs to the category of shell-shell activated carbon. Its main features are low density and light hand feeling. The weight in the hand is obviously lighter than that of coal-based activated carbon. The same weight of activated carbon, coconut shell activated carbon volume is generally larger than coal-based activated carbon.
2, coconut shell activated carbon shape is generally broken granular, flake, and molded activated carbon, such as columnar, spherical activated carbon, mostly coal charcoal.
3. Due to the low density of coconut shell activated carbon and light hand feeling, the activated carbon can be put into the water. The coal charcoal generally sinks faster, while the coconut shell activated carbon floats in the water for a longer period of time. If you add more weight, you will gradually sink into the bottom of the water. When the activated carbon is completely bottomed, you will see that each activated carbon is wrapped with a small bubble on the outside, which is crystal clear and very interesting.
4, coconut shell activated carbon is a small molecular pore structure, the activated carbon is placed in the water, the air discharged when the water molecules are adsorbed will produce many very small blisters (the naked eye can just see), densely floating to the surface. The coal-based activated carbon is generally a macromolecular pore structure, and the bubble phase produced is also large.
