YFFB elevator accompanying cable manufacturers tell you that in a sense, the wire and cable manufacturing industry is an industry of material finishing and assembly. The choice of materials will have a decisive impact on the manufacturing process, product performance and service life. Among them, the selection of copper wire is especially important, if a little carelessness may cause a safety accident. Below, the editor will sort out some reasons for the yellowing of copper wires and how to deal with them.

The yellowing of the copper wire in the YFFB elevator accompanying cable usually has the following reasons:
1. The temperature of the tin furnace is too high and the fluidity is large, resulting in too large pinholes in the coating and fast penetration of copper and tin.
2. The tin layer is too thin, and the penetration of copper and tin is fast.
3. There are too many halogen residues in the flux, and the pickling of the copper surface is not effective enough.
4. The packaging time is too fast, the heat is not dissipated, and there are too many impurities in the tin furnace.
5. The quality of the copper material is not good enough, and there are too many impurities.
6. The YFFB elevator accompanying cable manufacturer tells you that the temperature has an impact on the activity of copper atoms, and it turns yellow faster in hot days than in cold days.
These issues can be addressed by the following approaches:
1. The diameter of the mold is greater than the diameter of the wire +0.02mm (the purpose is very simple and the coating should not be too thin).
2. After production, it can be placed for about 2 hours before packaging (purpose: internal heat dissipation).
3. Buy a good flux and match the concentration of the flux, mainly because the flux affects the quality of tin plating.
4. Choose better oxygen-free copper wire.
The above is the reason and treatment method for the yellowing of the copper wire in the YFFB elevator accompanying cable, I hope it can help you.
