摘要

CORROSION INHIBITION OF ROADDEICING AND DUST CONTROL SALTSABSTRACTA process of milking a deicing or dust control agent withreduced corrosivity comprises mixing spent sulfite liquor and chloridesalt of an alkali metal or alkaline earth metal proportionally so thatthe ratio of lignosulfonate solids of the spent sulfite liquor to metalchloride salt is from about 1:25 to about 15:1 and the pH of the mix-ture is from about 4.5 to about 8.5. The sulfite liquor: chloride saltproduct can be spread onto road surfaces in dried form, sprayed on assingle or multiple solutions, and/or mixed with A non-slipping agent orthe like.
