GRANULATED ANTIICE MEANS AND A METHOD FOR MANUFACTURING THE SAME Russian patent published in 2006 - IPC C09K3/18 B01J2/16 

FIELD: icing protection.

SUBSTANCE: invention relates to production of substances preventing icing and accelerating thawing of snow and ice covers. Agent according to invention represents granules, each of which is made with internal sodium chloride nucleus and having external shell of calcium chloride, the latter additionally containing corrosion inhibitor so that composition of granules is as follows: 10-90% sodium chloride, 10-90% calcium chloride, and 0.5-20% corrosion inhibitor. Spraying of calcium chloride solution onto sodium chloride particles 0.5-5 mm in size is effected successively in direction of movement of sodium chloride particles along drying chamber at 130-150°C and 2-3 m/sec at the beginning to 170-190°C and 3-4 m/sec at the end.

EFFECT: increased melting and permeating power of granules and reduced dust escape and specific power consumption in drying operation.
