CRUDE MIXTURE FOR PRODUCING NON-COMBUSTIBLE, NONTOXIC HEAT- AND SOUND-INSULATING MATERIAL BASED ON FINE MINERAL FOAM

摘要

FIELD: chemistry.;SUBSTANCE: crude mixture contains the following components in wt % per dry substance: chrysolite asbestos - 13-20, ultra-thin basalt fibres with diameter of 0.5-3.0 mcm - 40-50, surfactant (wetting agent SV-102) - 20-25, hydrophobisation liquid - 6-13, colloidal silica (silica sol-KS) - 10-15, wherein the ratio of content of asbestos to basalt fibre is equal to 1:3.;EFFECT: improved operational characteristics, high mechanical strength and environmental safety while preserving incombustibility.;2 tbl
