    摘要： Aqueous compositions and low temperature processes for treating clean steel and galvanized steel to provide a coating suitable for the application of paint thereto. The aqueous treating compositions contain:______________________________________ Ingredient Quantity ______________________________________ zinc ion from about 0.9 to about 2.5 g/l; nickel ion from about 0.6 to about 2.0 g/l; orthophosphoric acid from about 15 to about 45 g/l; nitrate ion from about 1.0 to about 10.0 g/l. ______________________________________ The pH of the composition is adjusted to 3.0-3.5 by addition of alkali metal hydroxide. The above composition is used on clean galvanized steel. For clean ungalvanized steel, from about 0.10 to about 0.65 g/l of nitrite ion is included in the composition. Optional ingredients in the above compositions include chlorate ion, ferric ion, and a fluoride compound.The invention also relates to a metal activating composition comprising an aqueous colloidal solution of manganese ion and a titanium compound.

    摘要： This invention is directed to a method for treating metal surfaces. More particularly, this invention is directed to an improved method for cleaning, scouring, and activating metal surfaces prior to phosphatization, which comprises contacting said metal surfaces with an aqueous solution comprising primary and/or secondary alkali metal or ammonium salts of orthophosphates and conventional metal cleaning components, the solution having a pH value of from about 6.3 to 8.2, said pH being lower than the pH value of solutions of the corresponding secondary orthophosphates alone having the same concentration; and containing optionally condensed phosphates in an amount corresponding to the amount necessary to soften the water hardness of the water used.

    摘要： The present invention relates to an improved method of preparing titanium-containing phosphate conditioners useful in cleaning and activating the surface of ferrous, zinc or aluminum metal and alloys thereof for subsequent reaction with phosphate coating solutions. The method comprises the steps of(a) preparing a mixture consisting essentially of water, sodium tripolyphosphate, disodium phosphate and a titanium-containing compound and(b) adding said mixture to solid disodium phosphate with mixing whereby a solid titanium phosphate composition is obtained.The invention provides a method for forming a dry activating composition which does not require the application of any energy such as heat to the material. When the solid titanium phosphate compound is dissolved in water to form pretreatment solutions it can be employed successfully for activating metal surfaces in preparation for reaction with phosphate coating solutions.

    摘要： Metal surfaces are cleaned, prior to phosphating or the like, with compositions containing alkali metal (especially sodium) silicates and chlorides, and preferably also containing surfactants and chelating agents. These compositions have cleaning power comparable to phosphate-containing cleaners and cause less water pollution upon discharge into natural waterways.

    摘要： Disclosed is a system for maintaining a pretreatment bath containing a pretreatment comprising a Group IVB metal. The system comprises an aqueous reducing agent comprising a metal cation and a latent source of sulfate which, upon reaction with a contaminant in the pretreatment bath, forms a metal sulfate. The contaminant comprises a nitrite source. The metal sulfate salt has a pKsp of 4.5 to 11 at a temperature of 25° C. Also disclosed is a method for maintaining a pretreatment bath containing a pretreatment composition comprising a Group IVB metal. The method comprises supplying the reducing agent to the pretreatment bath in an amount sufficient to reduce a pollution ratio of the pretreatment bath to less than 1:1. Also disclosed are substrates with a pretreatment bath maintained according to the system and method.
