Abstract

Froth-stabilizing agents which reduce the surface tension and increase the viscosity of the solutions are added to flux washes comprising dilute aqueous solutions of fluxing compounds such as hydrochloric acid, zinc chloride, salammoniac, or zinc ammonium chloride. Froth stabilizers referred to are glycerine, tallow, oatmeal, bran, glucosides such as soapbark, licorice root, saponin, amygdalin, phloridzin, populin, salicin, soap wort root, or tannin, and carbohydrates such as xylose, dextrose, cane sugar, galactose, lactose, maltose, corn starch, or potato starch.ALSO:The surface of a metal to be galvanized is prepared by passing the metal through a flux wash comprising a dilute aqueous solution of a fluxing compound such as hydrochloric acid, zinc chloride, salammoniac, or zinc ammonium chloride, and a froth stabilizer which reduces the surface tension and increases the viscosity of the solution. The froth stabilizer may be glycerine, tallow, oatmeal, bran, a glucoside such as soapbark, licorice root, saponin, amygdalin, phloridzin, populin, salicin, soap wort root, or tannin, or a carbohydrate such as xylose, dextrose, cane sugar, galactose, lactose, maltose, corn starch, or potato starch. When a salt such as zinc chloride &c. is used in the flux wash the solution carried into the molten zinc bath by the metal causes the formation of a frothy flux blanket on the surface of the molten zinc. The flux blanket is continually renewed by the entering metal and spreads gradually over the surface of the zinc, spent flux being removed at a point remote from the point of entry of the metal.
