More Information
Summary:The calcium silicate molded article is manufactured by: (a) reacting a mixture of siliceous and calcareous raw material and a diluted water glass at the room temperature and pressure to make a raw slurry contg. amorphous calcium silicate; (b) agitating and hydrothermally reacting it at 190 deg.C or more and 15 kg/cm2 saturated vapor pressure or more to make an aq. hydrous calcium silicate slurry; (c) adding 0.1-10 wt.pts cationic flocculent and 0.2-20 wt.pts anionic and nonionic flocculent, and 0.25-20 wt.pts reinforced fiber to the slurry; and (d) molding the mixture, and drying it. The molded article is used as refractory, water-absorbing and insulating materials.
