PROBLEM TO BE SOLVED: To provide a polyethylene-based open cell suitable as an adsorbent for ammonia, formaldehyde and the like, and a method for producing the same. SOLUTION: A carbon powder obtained by pulverizing a wood chip carbide obtained by stacking a wood chip, a rice husk and / or sawdust on the fuel material layer in this order and carbonizing the wood chip, and a polyethylene resin A foaming agent and a cross-linking agent are added to the mixture, and the kneaded foamable crosslinkable composition is heated and foamed in a non-hermetic mold to form a foam, and then subjected to mechanical deformation to make the foam open. A method for producing a powdered polyethylene-based open cell. |
