The use of coconut shell quality materials, specially activated by the process, has a higher hardness and surface area, strong acetic acid and zinc acetate adsorbability. Widely used PVA (polyvinyl alcohol), etc. vinylon carriers and other high-level use products.
      Reference indicators: Moisture ≤ 5%, Ash ≤ 2%, acetic acid adsorption ≥ 550mg / g, zinc acetate adsorption ≥ 7.0g/100ml, hardness ≥ 90%, specific surface area ≥ 1300 m2 / g
