HUMIDITY CONDITIONING MATERIAL UNDER THE FLOOR

摘要

PROBLEM TO BE SOLVED: To improve a rot proof function and an insect proof function by using lumbers which use CCA. SOLUTION: In a humidity conditioning material 1 under the floor which is laid under the floor 2 and is composed of charcoal, charcoal is constituted by charcoal chips M obtained by crushing a lumber which uses CCA agent containing chrome, copper, and an arsenic compound by applying it thereon or impregnating it therein and carbonizing raw material chips obtained by crushing the lumber which uses CCA and is constituted by so-called EM which consists of useful microorganism groups by applying microorganism groups actively to the charcoal chips M. Consequently, it is possible to improve a rot proof function and an insect proof function furthermore and suppress the generation of mold and termite more securely because remaining chrome and the arsenic component give the rot proof function and the insect proof function. Moreover, it is possible to use a waste material such as an electric light pole as the lumber which uses CCA to achieve extremely useful utilization of it.
