13. How to anti-oxidize the copper tube of the mold?

[vc_row][vc_column][vc_column_text]

The mold copper tube has good thermal conductivity and other physical properties, but it is easy to oxidize in the air. The anti-oxidant, also known as copper anti-oxidant treatment, can improve the anti-discoloration and anti-oxidation ability of the copper tube of the mold. A passivation film is formed on the surface to prevent the surface from darkening, and to improve its anti-corrosion, anti-discoloration, anti-oxidation ability, and does not affect the welding performance. In particular, mold copper tubes are used, which are passivated after polishing. The stock solution of antioxidant amount can be used directly. The anti-oxidation protective agent is the last anti-oxidation process in the copper polishing process. During the use process, the workpiece should be immersed in the chemical and shaken slightly so that the workpiece can fully contact the chemical. Antioxidant protective agent has no irritating odor, simple operation and high production efficiency. However, after the workpiece has been treated with the potion, the surface must be cleaned with clean water or pure water. Otherwise, the workpiece surface will be affected.

The anti-oxidation process of the crystallizer copper tube is: degreasing→washing twice→polishing→washing twice→antioxidation treatment→washing twice→drying.

The use of antioxidants can improve the service life of the copper tube of the mold.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_btn title=”About LMM GROUP” link=”url:https%3A%2F%2Fwww.lmmgroupcn.com%2Fabout-lmm%2F|target:_blank”][vc_column_text css=”.vc_custom_1649296177864{margin-top: 50px !important;}”]friendship Link:
