How to distinguish the waterproof type and ordinary type of honeycomb activated carbon?
Differences in materials and structures First of all, from the perspective of material composition, waterproof honeycomb activated carbon and ordinary type may be similar in basic materials. Both use high-quality coal, wood or coconut shell as raw materials, and are made through processes such as crushing, mixing, extrusion molding, carbonization and activation. However, during the post-molding processing of waterproof honeycomb activated carbon, one or more layers of waterproofing agents will be added. These waterproofing agents are mostly inorganic or polymer materials, which can form a dense protective film covering the surface of activated carbon, effectively preventing water penetration, thereby maintaining the stability of its internal structure and adsorption efficiency. In contrast, ordinary honeycomb activated carbon has not undergone such waterproofing treatment, and its surface is relatively open. Although it is conducive to the rapid passage and adsorption of gas or liquid, it is easy to cause pore blockage due to water absorption in humid or water-containing environments, affecting adsorption performance and service life. Adsorption performance and application areas In terms of adsorption performance, waterproof honeycomb activated carbon can maintain high adsorption efficiency and stability in high humidity or underwater environments because it effectively prevents water from eroding the internal structure....
