Arc coating technology nearly 20 years of development in materials, equipment and applications quickly, mixer mechanics, its working principle is to be sprayed two wire as a consumable electrode, driven by a variable speed electric motor, mixer maintenance master, the lance a short circuit caused by electric arc intersects mouth melted, atomized into fine particles by means of compressed air and high-speed playing in the working surface pretreated to form a coating. It is a high efficiency of spraying, combined with high strength, good quality spray coating method, with high energy efficiency, low investment in equipment and the use of cost, equipment is relatively simple, flexible operation, easy on-site construction and safety. Then roughed roughened to provide surface stress, Shaanxi mixer maintenance, increasing the surface area and cleanup coating and substrate binding, reduce stress coating cooling, alleviate stress within the coating, so conducive increase the bond strength. Sandblasting is the most common roughening process, mixer repair factory, sand with sharp, hard as well, the choice of quartz sand, silicon carbide and the like. After a fresh surface roughness can easily be oxidized or affected by environmental pollution, and therefore timely spraying, if placed over 4h will have to re-roughening treatment.
