Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.

3, with oil cloth (oil used cloth), carefully from inside to outside, including each cage wire repeatedly grinding many times. The front of the bird cage, the door flowers, where vision is often in place, are repeatedly rubbed in order to improve the surface finish, equivalent to “grinding”. Note: door flowers, arhat lines and other structures are delicate and fragile, do not break. This process, which requires time and patience, care, is also a process of observing and appreciating the cage. Use new cloth again, according to the above process, wipe again and again. This process is equivalent to polishing. For important parts, you can use a little force, the speed can be a little faster (do not use force). Be careful to fold the cloth neatly, otherwise marks will easily form. When this process is complete, the surface finish is significantly improved.
