Abstract

The invention relates to the field of metal plate surface treatment, and discloses a polishing method for the surface of a metal plate. The polishing method comprises the step that particles with the granularity smaller than or equal to 1 mm are used for conducting jetting treatment on the metal plate, and the jetting pressure is 1-4 MPa relative to each square meter of metal plate. After shot blasting polishing is conducted on the metal plate through the method, a surface oxidization film can be effectively removed, the traditional HF solution immersing and the influences on the human bodies and the environment are reduced, and the polishing method is more suitable for irregular components. The production technology is simple, and operation is easy. When anodic oxidation is conducted on the surface of a titanium alloy plate polished through the technology, in the same solution concentration, the voltage used for obtaining the same color is relatively low, and therefore the power utilization cost can be greatly reduced. Under the situation of further optimization, the metal plate is subjected to further electrochemical polishing treatment through 5-15% of sulfuric acid, the smoothness and flatness of the obtained metal plate can be further improved, and the surface performance of the obtained metal plate can be further improved.

Description

technical field [0001] The invention relates to the field of metal plate surface treatment, in particular to a method for polishing the surface of a metal plate. Background technique [0002] At present, domestic and foreign manufacturers will form a dense oxide layer on the surface during the production of titanium and titanium alloy plates. This oxide layer is difficult to remove during subsequent surface anodic oxidation treatment or other surface process construction. The traditional treatment method is to soak the surface of titanium and titanium alloy plates with HF solution or use a polishing machine to polish the surface of the plate, and then soak in HF solution to completely remove the oxide layer on the surface, and then perform surface treatment, etc. process. [0003] However, because HF solution is highly corrosive, highly polluting and highly volatile, it will cause serious harm to the environment and the body of the staff. It is not suitable for large-scale...
