Treatment method for preventing elution of lead from lead-containing copper alloy |
| abstract |
(57) [Abstract] [Problem] A method to prevent lead from eluting into water used from water supply fittings of water supply equipment made of lead-containing copper alloy material [Solution] Manufacture from lead-containing copper alloy material After cleaning the surface of the supplied water fittings with an alkaline degreasing solution containing caustic soda and a surfactant as a pretreatment, and then plating by a normal nickel and chromium plating process, an aromatic heterocyclic compound such as benzotriazole is used. Method for preventing elution of lead into water by forming a strong film on the surface by immersing in a chromium-containing chromate treatment solution containing phosphoric acid and a phosphate aqueous solution or an acidic solution or an alkaline solution or a neutral solution |
