<p>PROBLEM TO BE SOLVED: To provide a method of manufacturing an inorganic board without containing asbestos having a high interlaminar bonding without lowering productivity. SOLUTION: In the method of manufacturing the inorganic board without containing asbestos wherein raw material slurry containing at least a cement ingredient, pulp and/or organic based reinforcing fiber and a filter auxiliary agent as a solid content is laminated by a paper making process, molded and cured, the raw material slurry is made into paper with a paper making machine, transferred to a felt and a thickner composition containing 0.05 to 2.0 wt.% of a thickner ingredient containing at leastβ-1,3-glucan is spreaded on a surface of a paper-made single layer obtained by being transferred onto the felt. Thereafter, it is rolled on a laminating roll, cut out, molded and cured at >=60 deg.C.</p> |
