METHOD OF PRODUCTION OF THE ANTI-ICING REACTANT Russian patent published in 2006 - IPC C09K3/18 

FIELD: motor-car industry; other industries; methods of production of the anti-icing reactant.

SUBSTANCE: the invention is pertaining to the method of production of the anti-icing reactants for maintenance of roads in winter. The method of production of the anti-icing reactant based on sodium chloride and calcium chloride provides for mixing of the sodium chloride with calcium chloride and their heating and drying. Sodium chloride crystals are coated with the atomized solution of calcium chloride and dried in the "boiling bed" kiln with production of the double-layer granules, the outer layer of which is composed out of calcium chloride. Sodium chloride crystals are coated with calcium chloride in two phases. The forming small particles of calcium chloride are fed into the cyclone, whence the cyclone dust of the calcium chloride is fed into the mixer for intermixing with the wet crystals of sodium chloride. The produced anti-acing reactant has the improved physicochemical thermodynamic properties.

EFFECT: the invention ensures, that the produced anti-acing reactant has the improved physicochemical thermodynamic properties.
