Machining a workpiece with a processing machine dimensions or function change process. By temperatures in the workpiece machining is divided into cold and hot processing. Usually at room temperature processing, and does not cause the workpiece chemical or phase changes, called cold. Usually above or below normal temperature processing, the workpiece can cause chemical or phase changes, said thermal processing. Cold press processing methods are not the same and can be divided into cutting pressure processing. There are common heat treatment thermal processing, forging, forging and welding. Work electrostatic spraying gun or spray pan, spray cup, then negative and some spray paint particles, then the positive electrode and the workpiece ground in high voltage power supply high voltage effect, gun (or spray pan, spray cup) of the ends of the workpiece Inter constitute an electrostatic field. Paint particles that have been field force and the electrostatic field voltage and paint particles with electricity proportional and inversely proportional to the distance between the gun and the workpiece, when the voltage is high enough, the lance end zone adjacent areas which air ionization, air violently ionization and heat, so that a sharp edge or pole lance end around the needle to form a dark red halo, the dark privately significantly visible, then violent air attack corona discharge. Plenty of coat planning is to ensure that the role of the outer protective layer of foundation and conditions: hardware appliances spraying, currently the country engaged in the metal thermal spray engineering unit a lot, but skills development is very uneven. Many units in an engineering base do not understand the working parameters and cause failure analysis, regardless of the pipe heating surface erosion wear failure is still the high-temperature oxidation and high temperature corrosion failures, and whether the sulfate corrosion is still sulfide corrosion, Thinking is not there will not affect the Steam Soot and smoke corridors, all use the same kind of information to make a protective layer. One can imagine that regardless of condition, nor the failure cause analysis of the workpiece base coat planning is unable to ensure the application of the practice effect. Therefore, our company attaches great importance to the metal thermal spraying skills seminars, the National Thermal Spray Association members, but also the appearance of Engineering Association member units of hardware spraying equipment, understand and master the most advanced metal thermal spray coating line hardware skills, for each project must be carefully analyze, understand the working parameters of American Standard Hardware spraying plant, failure cause analysis of the workpiece, make coat planning on this basis, to ensure that the role and use of project planning for.
