PURPOSE:To produce calcium silicate materials having long-term antimicrobial and antimycotic properties by blending calcium silicate with soluble glass to elute copper or silver ion in the state of powder, etc. CONSTITUTION:Gypsum is blended with about 0.1 to 15wt.% soluble glass to elute copper or silver ion is made into powder, bead or fibrous state. Consequently, silver or copper ion having antimicrobial or antimycotic properties is gradually eluted at a constant rate for a long period time, bacteria and molds are prevented from occurring in calcium silicate material and discoloration resulting from molds, etc., is hindered. |
