Method of manufacturing a calcium silicate board |
摘要 |
<p>A method of manufacturing a calcium silicate board having a bulk specific gravity of 0.70 or less comprising: a step of forming a material slurry in layers, said material slurry comprising, as a solid component, 5 to 35 wt% of calcareous material, 5 to 40 wt% of silica containing material, 2 to 8 wt% of fiber material, 5 to 40 wt% of inorganic fillers, and a gel obtained from 2 to 20 wt% of calcareous material for gelation and 3 to 25 wt% of silica containing material for gelation; and a step of a hydrothermally reacting the obtained molded body in a pressure container, wherein 2 to 20 wt% of at least one kind of amorphous silica containing material and/or silicate material, each having a specific surface area of 1 m<2>/g or more, is used as a portion of said silica containing material; and, before said hydrothermal reaction, said molded body is subjected to primary curing under conditions where (curing temperature - 15) x curing time≥120 DEG C.hr. so that the flexural strength of said molded body under a wet condition is 7 kg/cm<2> or more and is 1.3 times higher than that before primary curing.</p> |
