vent mesh for bugs

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.

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.

At present, there are two main kinds of electric galvanized wire products, hot dip galvanized wire and electric galvanized wire. The difference is that the way of galvanizing is different, and the quality of the products is different. Hot dip galvanized wire zinc layer thick, corrosion resistance is stronger, but correspondingly, the price is high. Galvanized wire zinc coating thin, corrosion resistance is poor, but the price is low.
