Hot plating wire in the manufacturing process, because of the impact of the environment, will cause the appearance of galvanized black, during which some related factors such as humid air, impurities in the manufacturing process, hand sweat and lubricating oil, will cause the appearance of galvanized black. Some simple solutions can avoid hot plating wire in the manufacturing process, blackening or extending the discoloration moment, such as the work site adhere to boring, cut and do not need chemical substances, the operator with clean gloves, etc.
Zinc passivation treatment must be carried out after zinc immersion. Zinc passivation treatment has a good anti-discoloration effect, which can be used to extend the moment of discoloration. The two can be used in connection with the use of discoloration. The advantages of annealing wire: black wire has very good elasticity and flexibility, can control its degree of softness and hardness in the annealing process, made of high quality wire, mainly used for binding wire and binding wire in the construction industry.
The main wire number is 5#-38#, which is softer and more flexible than ordinary black iron wire. The softness is uniform and the color is consistent. Annealing wire is also widely used, wire mesh weaving after plating, plating and other methods, after the treatment of the wire or wire mesh has good corrosion resistance, oxidation resistance characteristics, so used in other aspects can better play the role of annealing wire.
