Description

Technical Field

[0001] The invention relates to the technical field of metal composite plate processing, and in particular to a surface treatment device for a nickel-based alloy composite plate. Background Art

[0002] Nickel-based alloy composite plate is a new type of metal structural material. By combining nickel-based alloy with substrate, the corrosion resistance, wear resistance and high temperature performance of nickel-based alloy are fully utilized, while taking advantage of the high strength and low cost of substrate. This composite material is widely used in marine engineering, nuclear industry, single crystal silicon manufacturing and aerospace industry. Surface treatment is an important step in the processing of metal composite plates. The purpose is to improve the corrosion resistance, wear resistance and decorativeness of the material. Common surface treatment methods include pickling. Pickling is the process of using acid solution to remove oxides, rust and other impurities on the metal surface. This process is widely used in metal processing, electroplating, chemical industry and other industries. It aims to improve the cleanliness and finish of the metal surface and enhance the effect of subsequent processing or treatment. Before pickling, the metal workpiece needs to be pre-treated, such as degreasing and decontamination, so that the acid can better contact and remove the oxide layer and impurities on the surface.

[0003] Before the existing metal composite plates enter the pickling process, the impurities on the surface of the composite plates are generally purged by an automatic purge structure, or the impurities on the surface of the composite plates are sucked by a manually operated vacuum cleaner. The purge method easily causes high dust content in the workshop air, affecting the health of employees, while the manually operated vacuum cleaner method results in high labor production costs and insufficient suction effect.
