DEVELOPMENT AND ENGINEERING TEST REPORT, CHARGES, ANTIFREEZE, FIRE EXTINGUISHER, LITHIUM/CALCIUM CHLORIDE BASE

Abstract

This report covers development and engineeringtest phases for water additive charges, antifreeze, fire extinguisher, lithium/calcium chloride base. The report summarizes literature surveys and laboratory tests made. It is concluded that: (a) A solution having 20.0% CaCl2, 8.8% LiCl, and 71.2% H2O composition on a weight basis and having a density of 1.2265 at 68 F is satisfactory as a candidate antifreeze salt for winterizing water to -65 F; (b) Sodium chromate at a concentration of 1,050 mg/l of solution effectively inhibits the corrosive effect of the above salt solution on Al, steel, brass, Zn, Mg, and Cu; (c) Lithium-chloride solutions (approximately 23% LiCl by weight in water) are effectively nonfreezing to below minus 65 F and except for higher cost are as applicable for application in antifreeze charges as the CaCl2 LiCl mixture in solution with water; and (d) Dry packaging of salt charges including the inhibitor is feasible.
