Description

[Brief explanation of drawings]

In Figure 1, the left side of the composite wood fiber cement board is a plan view of a standard product, and the right side is a cross-sectional view. The plan view on the left shows wood fibers, 2 is cement particles, 3 is zeolite-processed ceramic fine particles, 4 is ferrous sulfate stabilized deodorant particles, and 5 is zircon sand fine particles, which are kneaded, molded, and solidified. , the right side is its cross-sectional view.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) Processing a base material such as fine porous zeolite into ceramic fine powder that has a low molecular gas adsorption oxidation-reduction catalytic function during the production of wood fiber cement boards, and A deodorizer made by stably processing ferrous sulfate, which has connectivity and is also fast-acting, and a material with adsorption redox performance of zircon sand fine powder, mixed with cement as a glue material. , the wood fibers are mixed with mixed water and molded, and the voids between the wood fiber materials are maintained appropriately to maintain curing, fast-acting and long-lasting deodorizing effects, as well as moisture control, A method for manufacturing composite wood fiber cement boards that exhibits the synergistic effect of original properties such as heat insulation, sound insulation, sound absorption, and flame retardancy. (2) When manufacturing wood fiber cement boards, wood fibers are processed into fine ceramic powder that has a low-molecular gas adsorption oxidation-reduction catalytic function by processing a base material such as fine porous zeolite, and this is mixed with water using cement as a binder. After kneading, molding, and curing, a long-lasting and fast-acting ferrous sulfate deodorizer made of stably processed ferrous sulfate is sprayed on the surface to permeate and adhere to the surface, absorbing bad odors generated in the building space and acting as an oxidation-reduction catalyst. Depending on the performance, it deodorizes and converts it into another odorless substance, and also suppresses ethylene gas generated from fruits, vegetables, fish and shellfish, farmed meat, etc. stored in the storage room, and adsorbs and oxidizes ammonia, hydrogen sulfide, mercaptan, etc. A method for manufacturing a composite wood fiber cement board capable of deodorizing and preserving freshness through catalytic action.
