An important indicator when buying activated carbon-density from Carrie Ge's blog

The activated carbon market in my country is very large. As a whole, there are many activated carbon manufacturers, and the products are countless. The quality of activated carbon is naturally uneven.

 

 Whether it is nutshell activated carbon or columnar activated carbon, there are many common identification methods on the market. ningxia yongruida carbon Take columnar activated carbon as an example, the common one is to identify the iodine value of columnar activated carbon, and the quality of columnar activated carbon can be simply measured.

 

But the iodine value does not completely represent the quality of columnar activated carbon, and density is also one of the important indicators for detecting the quality of columnar activated carbon.

 

Columnar activated carbon density:

The total amount of columnar activated carbon stacked in a unit volume, generally the better the columnar activated carbon, the more sufficient the pore space, the less the mass of columnar activated carbon stacked in the unit space, and the smaller the amount and weight of columnar activated carbon.

 

Common density of activated carbon:

 

The density of columnar activated carbon is generally between 0.5g-0.7g/cm3, the lower the density, the better the quality of columnar activated carbon.

 

The density of powdered activated carbon is between 0.38g-0.45g/cm3: Because the powdered activated carbon is fine enough and the particles are small enough, the adsorption space of the powdered activated carbon is very abundant, and the relative density of powdered activated carbon is naturally much lower.

 

The density of nutshell activated carbon is about 0.45-0.65g/cm3. Due to the good pore distribution of raw materials such as nutshell, the density of nutshell activated carbon is naturally much better than other activated carbons.

 

The density of coal-based activated carbon is between 0.45-0.75g/cm3. Compared with coal products, raw materials such as husks do not have developed pores, so the density of coal-based activated carbon is lower than that of husk activated carbon.

 

When buying columnar activated carbon and other activated carbons, compare the density of columnar activated carbon, and naturally you can initially determine the quality of columnar activated carbon. www.wyactivatedcarbon.com
