    摘要: This invention discloses a process for activating steel surface prior to phosphating treatment wherein the steel surface is cleaned, the cleaned steel surface is then treated with an aqueous activating solution containing titanium and pyrophosphate ion, and thereafter the steel surface is treated with a phosphating solution, characterized in that magnesium ion is included in said aqueous activating solution in order to suppress formation of an inactive film on said steel surface due to the presence of said pyrophosphate ion, and then said steel surface is treated with the resulting aqueous activating solution.

    摘要: A durable hydrophilic surface can be formed on metals by coating them with a composition containing a first water soluble polymer based on polyacrylamide, a second water soluble polymer with at least 60 mole percent of ionizable groups such as acids and quaternary ammonium salts, and a cross linking agent. Water soluble chromium and zirconium salts that can form complexes with the first water soluble polymer are preferred crosslinking agents. The invention is particularly useful for aluminum to be used in heat exchangers.

    摘要: In the phosphate immersion treatment of a steel sheet structure such as an automobile body, a method is provided wherein the bottom of a treatment tank is flat. An object to be treated such as an automobile body is submerged in the treatment solution. The object to be treated is inclined upward and downward at least once to remove oil, reaction cases, and air collected inside the object. An apparatus for performing phosphate immersion treatment of the object is also provided wherein the treatment solution is sprayed toward the feeding side of the treatment tank to cause small waves, so that formation of a border line mark on the surface of the object due to temporary interruption of the feeding operation may be prevented. An undulation is formed in a conveyor arranged above the treatment tank, or a pair of drop lifters which are individually operable are mounted to the conveyor, so that the object may be inclined upward and downward.
