METHOD OF WATER GLASS PRODUCTION Russian patent published in 2002 - IPC

FIELD: technology of water glass production in manufacture of building materials. SUBSTANCE: method includes preparation of suspension in solution of sodium hydroxide from silica- containing amorphous material-microsilica in from of waste of crystalline silicone with particles sizing (0,01-10)•10^-6 m with ratio of solid and liquid phases in suspension S:L=1: (1.9-5.65) with subsequent hydrothermal treatment of suspension at atmospheric pressure and temperature of 75-80 C for 9-63 min. EFFECT: produced qualitative homogenous product possessing sufficiently high viscosity, good adhesive and binding properties from microsilica with fairly wide range of particle sizes. 1 tbl
