  • Fourth, the difference between 201 and 304 is the problem of nickel. And the price of 304 is relatively expensive now, generally close to 20,000 yuan per ton, but 304 can at least ensure that it will not rust in the process of use. (Experiment with potions)

  • In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

  • As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
