Subject :Three differences between nutshell activated carbon and columnar activated carbon
Material difference:
Nutshell activated carbon represents wood activated carbon. The products are mainly made from coconut shells, apricot shells, jujube shells, etc. through carbonization, activation and other processes.activated carbon manufacturer It has high strength and developed micropores. It is suitable for all kinds of pure water, drinking water, High-standard industries such as food.
Columnar activated carbon represents coal-based activated carbon. The main raw materials of this type of activated carbon are anthracite, lignite and other materials, which are coal-based processed products. Columnar activated carbon is cheap, with well-developed mesopores, and is suitable for various sewage treatment industries.
Appearance difference:
Generally, nut shell activated carbon has a large adsorption space, which is basically small particles, has a fixed shape, has a small density to pick up, and feels light. Compared with coal-based columnar activated carbon, it is significantly lighter.
Coal-based activated carbon is mostly broken particles, flakes, and other structures. Formed carbon is mainly columnar activated carbon, spherical activated carbon, and coal-based granular activated carbon. Coal-based activated carbon has a high density and is obviously heavier than nutshell activated carbon in the hand.
Price difference:
The price of nut shell activated carbon is higher than that of columnar activated carbon. Coconut shell activated carbon is a better kind of nut shell activated carbon. Many of its raw materials are imported from Southeast Asia, which makes the price of coconut shell activated carbon higher than that of columnar activated carbon.
Since the raw material of columnar activated carbon is coal products, my country has a lot of resources, and there is a lot of gap in cost. activated carbon extracting gold Therefore, the price of columnar activated carbon is more advantageous than that of nutshell activated carbon. This is the intuitive gap between nutshell activated carbon and columnar activated carbon. Both have their own merits and have their own special fields, so there is no need to deliberately compare them. |
