CORROSION INHIBITORS INVESTIGATION

CORROSIVE EFFECTS OF THE WINNIPEG DE-ICING AND SURFACE CONTROL TECHNIQUE ON VEHICLES, PAVING MATERIALS AND OTHER AFFECTED MATERIALS WERE STUDIED. CHEMICAL ADDITIVES TO THE SALT, INHIBITORS, WERE USED TO REDUCE THE ELECTROLYTIC EFFECT OF MELTED ICE, AND THE EFFECT OF THE RESULTING CONCENTRATION CELL PRODUCED OR TO PASSIVATE A STEEL SURFACE. THE COST OF INHIBITION WAS LESS THAN $4.00 PER TON OF SALT AND APPEARED ACCEPTABLE IF CORROSION PROTECTION WAS AFFORDED. THE THREE INHIBITORS USED WERE CARGUARD, A PRE- TREATED ROCKSALT, A COMMERCIAL GRADE SODIUM HEXAMETAPHOSPHATE, AND AN INHIBITOR OF THE INTERNATIONAL SALT COMPANY. PRELIMINARY TESTS WERE PERFORMED TO DETERMINE THE EFFECTS OF CHEMICAL ADDITIONS TO SAND AS RELATED TO BRAKING DISTANCES OF VEHICLES ON A HARD PACK SNOW SURFACE. THE CORROSION RATES OF VEHICLES WERE COMPARED FOR THE WINTER SEASONS OF 1964/65 AND 1965/66. REFERENCES' DE-ICING CHEMICAL CORROSION INVESTIGATION. MANITOBA UNIVERSITY, SEPTEMBER 1965.
