Activated Carbon It has a wide range of applications and is involved in many fields. It can effectively adsorb some organic pollutants in water and has a special effect on purification, impurity removal and odor removal. How to select regions Activated carbon Next, experts tell you some common sense about shopping.

1. The two activated carbons have the same weight and the larger the volume, the stronger the adsorption capacity.

In order to improve the adsorption performance of shell activated carbon, it is only necessary to make as many pore structure focus real estate networks on activated carbon as possible. The more pores, the looser the activated carbon, the lighter the relative density will be. Therefore, good activated carbon will feel lighter. Under the condition of the same weight packaging, the active carbon with good performance will be much larger than low-quality activated carbon. Haixin advanced air adsorption special shell carbon, common Coconut shell activated carbon The volume is larger than 1/3, the pore diameter is developed, the material is loose, and the same weight can absorb more harmful gases.

2. Whether coconut shell carbon or fruit shell carbon, high iodine value is good carbon.

Activated carbon relies on adsorption capacity to purify gas. Here is an important index of adsorption capacity - iodine value. The higher the iodine value, the stronger the adsorption capacity. Nowadays, coconut shell carbon is hot, but the iodine value of some coconut shell carbon that has not been activated or whose technology is not up to standard may not reach 500. Except for go2map, which is a well-known brand with certified effect, when we purchase most other activated carbon, we should ask the seller to show the iodine value test report.

3. It is very important to pack the carbon bag of activated carbon products from fruit shells.

Put the carbon bag on the mouth and blow. If the gas can easily pass through the carbon bag, it indicates that the air permeability of the carbon bag is good. If the charcoal bag cannot be blown, it is difficult for air to pass through, and the best charcoal installed there is hard to play a big role. As a passive adsorption product, the air must be able to penetrate into the deep layer of the carbon bag freely, so that the carbon bag can play a good role in air purification and adsorption. Theoretically speaking, tearing the carbon bag open and putting the carbon directly into the tray may be the best way for air permeability. Of course, this way has some impact on environmental health.

4. Bamboo charcoal we often hear is not activated charcoal.

The emphasis of each product is different. Bamboo charcoal has a certain adsorption capacity for moisture and can adjust the space humidity. However, the microporous bamboo charcoal has low iodine value and cannot be used as a harmful gas purification product. Its pore size has a weak ability to capture harmful gases and cannot firmly adsorb captured formaldehyde molecules.

After reading the above expert's method, I believe you also have some understanding of how to select activated carbon from fruit shells. In fact, as long as you carefully observe and find out, you can also summarize your own tips!
