FIELD: chemical technology.
SUBSTANCE: invention relates to technology for preparing anti-glazed preparations. Method involves mixing concentrated solutions of calcium or magnesium chloride as metal chlorides and ground sodium chloride in the required ratio to form suspension that is subjected for treatment in the boiling layer device. The suspension based on magnesium chloride is treated at temperature 110-140°C and the suspension based on calcium chloride is treated at temperature 130-170°C. Before the thermal treatment metal phosphates as anti-corrosive additives are added to the suspension. Hallite spent materials are used as sodium chloride and solutions obtained after processing carnallite ores are used as magnesium chloride. Method provides improvement of physical-mechanical properties of the preparation that provides uniformity of its applying on surface and promotes to uniform thawing the snow-glazed mass in roads.
EFFECT: improved and valuable properties of preparation.
