Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.

But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.

The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
