CALCIUM SILICATE PLATE AND PROCESS FOR PRODUCING THE PLATE

摘要

The present invention provides a method of manufacturing a calcium silicate board having a bulk specific gravity of approximately 0.5 to 0.8, which method achieves a decrease in the bulk specific gravity and an increase in the matrix strength of the board without impairing productivity, and the calcium silicate board obtained by this method. A method of manufacturing a calcium silicate board according to the present invention is characterized in that a material slurry comprising 5 to 30wt% of calcium silicate hydrate slurry as a solid component, 17 to 50wt% of calcareous material, 13 to 45wt% of silica containing material, 2 to 8 wt% of fiber material, and 5 to 40wt% of inorganic fillers is formed through conventional processes and the obtained molded body is subjected to a hydrothermal reaction in a pressure container.
