IMPROVEMENT OF METHODS FOR DECREASE OF RESUDUAL STRENGTH AND INVESTIGATION OF HARDENING NATURE OF SODIUM SILICATES IN LIQUID-GLASS MIXTURES AT CO*002-PROCESS

The investigation objects are the liquid-glass mixtures. The aim is to improve the technological properties of the liquid-glass mixtures and to investigate the mechanism of the their hardening by a carbonic-acid gas. The structure of the dispersion phase in the liquid glass has been made accurate; the new solid phases have been specified, and the structure of the binding component in the mixtures has been determined. The new explanation of the mechanism for hardening of the liquid-glass mixtures by CO*002 and drying has been proposed. The mechanism of decreasing residual strength of the mixtures under action of the water has been determined. The new procedure improving the knocking-out ability of the given kind mixtures has been developed. The new addition improving the knocking-out ability has been proposed. The developments have been put into the casting production.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
