What is 8mm columnar activated carbon? Coal based columnar activated carbon is a porous carbonaceous material with highly developed pore structure, making it an excellent adsorbent. The adsorption area per gram of activated carbon is equivalent to eight tennis courts And its adsorption effect is achieved through physical adsorption force and chemical adsorption force In addition to the carbon element, its composition also contains small amounts of hydrogen, nitrogen, oxygen, and ash, and its structure is formed by the stacking of six rings of carbon. Due to the irregular arrangement of six ring carbon, activated carbon has the characteristics of multiple micropores and high surface area.

8mm columnar activated carbon can be made from various carbonaceous materials, including wood, sawdust, coal, coke, peat, lignin, fruit kernels, hard fruit shells, sucrose pulp, bone, lignite, petroleum residue, etc. Among them, coal and coconut shell have become the most commonly used raw materials for manufacturing activated carbon. The production of coal based columnar activated carbon is basically divided into two processes. The first process includes dehydration and carbonization. The raw materials are heated, dried at a temperature of 170 to 600 ℃, and approximately 80% of the original organic matter is carbonized. The second process is to activate the carbonized material, which is achieved by reacting it with an activator such as water vapor and carbon. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the carbonized material to an appropriate temperature (800 to 1000 ℃) to remove all decomposable substances, thereby producing a developed microporous structure and a huge specific surface area, thus having strong adsorption capacity.

8mm columnar activated carbon is a porous carbonaceous material. Its developed pore structure gives it a large surface area, making it easy to come into full contact with toxic and harmful gases in the air. The activated carbon has strong adsorption capacity around its pores. To meet this requirement, the material selection and processing supply requirements for activated carbon are extremely strict. That is to say, the technical problem of activated carbon molding has not been solved, which has led to the application of deodorizing activated carbon packs overcoming the easy scattering of activated carbon powder or particles in practical applications. Easy to pollute. Not easy to save. Defects such as short usage time.
