According to the relevant industry insiders pointed out that manufacturers of brass flat wire will often encounter the problem that pickling process is not environmental protection, after heat treatment, the surface of this material often appears a layer of very thick oxide skin, the surface is black or brown and yellow, this layer of oxide skin is actually will bring a certain impact on the processing behind, therefore, It is necessary to carry out pickling polishing process, below, a simple introduction to this process.

Before pickling and polishing of brass flat wire, the corresponding preparatory work needs to be done. For example, the tank should be equipped first, and the environmental protection copper pickling and polishing liquid should be diluted into working liquid by 1 to 2 with water to prepare pre-acid lotion and prepare copper anti-color agent; Next is the pre-pickling process, the prepared brass flat wire for pre-pickling, in the pre-pickling tank liquid turn the copper wire, so that it is fully in contact with the liquid medicine, pickling time is usually in 1 minute.

The environmental protection copper pickling polishing process of brass flat wire is to carry out pickling polishing of the pre-pickling good flat wire. In the pickling process, the copper wire needs to be turned over to make the copper wire and the potion fully contact, in order to achieve the best pickling polishing effect.

When cleaning the brass flat wire, it is necessary to put the copper wire into the cleaning tank for cleaning, and then use the high pressure water gun for washing treatment, the surface of the residual acid rinse clean, to prevent the corrosion of the residual acid on the copper wire.

It should be noted that the anti-discoloration treatment process of brass flat wire can use the traditional process of industrial soapy alkali water for anti-discoloration treatment, of course, you can also use copper anti-discoloration agent for high strength anti-discoloration treatment.
