METHOD OF PRODUCING BAMBOO CHARCOAL, BAMBOO CHARCOAL, AND BAMBOO CHARCOAL-BLENDED SHEET

摘要

PROBLEM TO BE SOLVED: To remarkably improve functions required for a bamboo charcoal product such as a far-infrared radiation function while making the most of its advantage.;SOLUTION: Raw material bamboo charcoal obtained by firing a bamboo material is refired at 500 to 1,200°C for 5 to 11 hr. Thus, the one having a resonant frequency of 0.5 to 5 Hz and an electric resistivity of 1 to 3 Ω cm can be obtained. A bamboo charcoal-blended sheet consisting of a foamed sheet of a synthetic resin blended with the fine powder of the bamboo charcoal having a mean particle diameter of 5 to 30 μm in the ratio of 10 to 50 wt.% can be produced.;COPYRIGHT: (C)2004,JPO&NCIPI
