Abstract

The invention belongs to the technical field of surface treatment of metal materials, and particularly relates to a copper-zinc alloy treatment process. The copper-zinc alloy treatment process comprises the following steps: S1, placing down an alloy strip from a copper-zinc alloy material roll to be treated, and inserting the initial end of the copper-zinc alloy strip into a treatment device; S2,on the basis of the step S1, after the strip enters the treatment device, cleaning the surface of the alloy through a cleaning roller in the treatment device, removing grease and other impurities on the surface of the copper-zinc alloy, and after the surface of the strip is cleaned, passivating the surface of the strip; S3, on the basis of the step S2, carrying out surface cleaning on the passivated strip in the treatment device through high-temperature steam, and removing passivation treatment liquid remaining on the surface of the strip; and S4, on the basis of the step S3, drying the stripto obtain the treated copper-zinc alloy strip, and winding the treated copper-zinc alloy strip again to facilitate transportation or storage. The copper-zinc alloy treatment process is few in step andenvironmentally friendly, and the treated copper-zinc alloy is good in corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of metal material surface treatment, in particular to a copper-zinc alloy treatment process. Background technique [0002] Copper is extremely active chemically. Therefore, in the process of production, use and storage, it is inevitable to contact with oxygen and fine dust in the air, which can easily cause oxidation and discoloration of the copper surface. In the case of severe corrosion, the appearance and electrical conductivity of copper parts will be affected. Therefore, in the actual use process, it is necessary to treat the surface of the copper material to improve the corrosion resistance of the copper material and ensure that the surface of the copper material will not be oxidized and discolored, and at the same time, the electrical conductivity of the copper material will not be affected. [0003] There are also some technical solutions in the prior art, such as the Chinese patent whose applicati...
