摘要

PROBLEM TO BE SOLVED: To look to the safety of living environment by providing a simplified, dust-proof and gas-proof mask using a filter capable of sterilizing microbes and quickly absorbing and adsorbing harmful oxidizing gases including carbon dioxide, pollen, dust, fine particles, smoke, odor and the like by utilizing the multiplier effect of high material property activity and sterilizing activity of bamboo charcoal and high material property anti-oxidant force of chitinous chitosan calcium as a part of a means for protecting a person from contamination in these days when natural disaster occurs in succession in environmental contamination. ;SOLUTION: This good-quality, inexpensive simplified dust-proof and gas-proof mask uses a filter formed by processing bamboo charcoal burnt at a fixed temperature for a long time and having high material property activity and sterilizing activity into granular charcoal and powder charcoal, and mixing the processed charcoal with grain and powder made by processing sintered material having high material property anti-oxidant activity such as chitinous chitosan calcium burnt for a long time. This filter is capable of sterilizing microbes and quickly absorbing and adsorbing harmful oxidizing gases including carbon dioxide, pollen, dust, fine particles, smoke, odor and the like.;COPYRIGHT: (C)2001,JPO
