Anti-dusting treating method and treating agent for inorganic fiber containing building material

摘要

The present invention relates to an anti-dusting treating method and treating agent for inorganic fiber containing building materials which comprises impregnating an inorganic fiber containing building material with an aqueous solution of either a polyvinyl alcohol or a denatured polyvinyl alcohol. The present invention aims at preventing dusting of a building material containing an inorganic fiber such as asbestos by impregnating such an inorganic fiber containing building material with a polyvinyl alcohol or denatured polyvinyl alcohol aqueous solution. The polyvinyl alcohol or denatured polyvinyl alcohol employed in the present invention has excellent penetrating and film-forming properties, and the impregnated polyvinyl alcohol or denatured polyvinyl alcohol serves as an adhesive by which inorganic fibers such as asbestos fibers are fixed. Therefore, it is possible to facilitate the impregnating operation and obtain satisfactory anti-dusting effectiveness.
