The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.

The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.
