SNOW MELTING AGENT AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a snow-melting agent capable of strongly fixing to ice and snow surfaces and provide a method for producing the snow-melting agent. SOLUTION: This snow-melting agent comprising a granulated product E in which seed particles C containing sodium chloride crystals are coated to be surrounded with granulated layers containing calcium chloride is produced by fluidizing the seed particles C in a fluidized layer 1 and spraying a calcium chloride-containing solution B to the particles during fluidizing the seed particles C in the fluidized layer 1 and irregularly forming a large number of protrusions by growing granulated layers in silver frost shapes.
