114 copper protective agent copper anti-discoloration agent copper antioxidants copper sealer

114 a copper anti-discoloration agent, the nature and function of copper and copper-aluminum alloy has good heat conductivity, calendar and other physical and mechanical properties, but the air is unstable, easily oxidized. Use of the company's 114-protecting agent, can improve the corrosion resistance of copper and copper-aluminum alloy, anti-discoloration, oxidation ability, can form a passive film on the surface to prevent surface darkening and passivation does not affect the welding performance. Second, the slot and the amount of craft 114: 1 volume of 114 plus 9 volumes of water (10% concentration) Time: 3-5min temperature 20-50 ℃ Third, the use of copper polishing passivating agent 114 processing the last of the antioxidant process, using the process to make the workpiece immersed in Pharmacy and a little shaken, so that the workpiece full contact agents. The pharmaceutical odorless, easy operation, high production efficiency. But piece after syrup treatment, must be approved by surface water or washed with deionized water, or on the surface affected. Four process degreasing → washing twice → plating, polishing, or 10% sulfuric acid activation → washing twice → passivation → washing twice → drying.
