D, coating adhesion; The zinc layer of the plating parts should be firmly combined with the base metal with sufficient adhesion strength, and will not fall off or bulge after the hammer test.

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

5, when limited by the terrain, the barbed rope barbed rope protective net before and after the continuous setting, take the place as the end of the barbed rope protective net, and deal with the end of the sealing.
