How to identify the quality of nutshell activated carbon from Carrie Ge's blog

Consumers are reminded that when buying nutshell activated carbon, you must choose a product with a higher reputation, and carefully check the product name, production date, shelf life and related indicators.

Generally speaking, the finer the nutshell activated carbon particles, the larger the surface area, and the stronger the adsorption capacity. activated carbon powder There are several simple methods to determine the quality of nutshell activated carbon.

1. Look at the density

Generally speaking, the better the quality of husk activated carbon, the higher the iodine value. Due to the abundant adsorption space, the specific gravity of husk activated carbon is very light. Take a handful, the lighter the husk activated carbon is, the better.

2. Look at the bubbles

Throw a handful of nutshell activated carbon into a beaker filled with water, and a series of small dense bubbles will appear, accompanied by a sizzling sound. You can compare two different nutshell activated carbons. The more intense the phenomenon, the longer the duration. The longer the shell activated carbon is, the better.

3. Look at discoloration

The decolorization ability is also a major feature of nutshell activated carbon. Put the nutshell activated carbon in the ink for a period of time, and the color of the water that comes out will obviously change. Compare the decolorization ability of the nutshell activated carbon.

4. Look at adsorption

Remove a sample of husk activated carbon and put it on the tip of the tongue. If it is good charcoal, the sensation of adsorption will be transmitted on the tip of the tongue. The better the husk activated carbon, the stronger the effect.

5. Look at deodorization

Take a paper cup and spit a few smoke into the cup. Let it sit for a few minutes and you will find that the smell of smoke remains inside the quilt. chengde wanyang activated carbon At this time, put a small amount of nutshell activated carbon in the quilt, seal the cup and wait for a few minutes, and then look inside the quilt Whether there is residual smoke smell.
