Abstract
For producing amorphous sodium silicates having a water content of 0.3 to 6% by weight and an SiO2/Na2O molar ratio of (1.9 to 2.8) : 1 from a waterglass solution containing at least 20% by weight of solids, the water-glass solution is obtained by reacting quartz sand with sodium hydroxide solution at an SiO2/Na2O molar ratio of (2.0 to 2.8) : 1 at temperatures of 180 to 240°C and pressures of 10 to 30 bar. This waterglass solution is treated in a spray-drying zone with hot air at 200 to 300°C for a residence time of 10 to 20 seconds and at a temperature of the exit gas leaving the spray-drying zone of 90 to 130°C, to form a pulverulent amorphous sodium silicate having a water content (determined as the loss on ignition at 700°C) of 15 to 23% by weight and a bulk density of more than 300 g/l. The pulverulent sodium silicate is introduced into an obliquely arranged rotary kiln fitted with devices for moving solids and treated therein with flue gas in countercurrent at temperatures from 250 up to 500°C for 1 to 60 minutes. The rotary kiln is here insulated in such a way that its outside wall temperature is less than 60°C. Finally, the amorphous sodium silicate emerging from the rotary kiln is com-minuted by means of a mechanical crusher to grain sizes of 0.1 to 12 mm.
