Spraying in practice, often there will be some paint disadvantages, such as tilt, inappropriate speed, improper stacking, overspray and conceal improper, this is because there is no method to master the technology to use the gun. To avoid this situation, you need to grasp the following questions: ① grasp the gun with the spray angle in moving the process components. Distance and angle of the gun it is necessary to be consistent, according to the film's effect adjustment gun movement speed and spray width of overlap position. ② master the spray pressure, the pressure is not suitable for care and stability. This is the end of the table after a gun or guns with digital pressure control equipments to schedule. Care is not the same type of paint spray guns and pneumatic painting has a different need. Improper air pressure will cause the assumed color differences, cellulite and sagging and other adverse effects. ③ master mist form. ④ master gun movement speed. ⑤ master spraying methods, the road. Tu device features the leading manufacturer is a necessary condition excellent coating: metal thermal spraying include flame spraying, plasma spraying, arc spraying and blasting spray four categories, including plasma spraying and spraying suited blasting boiler plant site operations spraying equipment, arc spraying and flame spraying the field operating conditions can be satisfied, but the flame spraying slow, long duration, is sprayed parts prone to stress concentration and deformation, and arc spray skills was able to excellently satisfied Boiler site a large area using a variety of conditions . Selection of supersonic arc spraying equipment is imported from abroad spraying equipment, it is usually compared with the domestic arc spraying machine, spraying has several strengths, mainly reflected in: the choice of burning to an arc spraying skill ends of the wire fed uniformly wire molten metal spray paint, supersonic jet by Laval nozzle to speed up after the melting of the wire atomized into fine particle size, distribution uniform particle coating process, constitute a coating sprayed workpiece. Because the choice of the Laval nozzle to speed up the melting of particles flying skills to reach supersonic speed, the 386M \ S. Melting the primary particles and the substrate by mechanical, physical and metallurgical methods such as contact, their contact strength up to 40Mpa above, porosity ≤0.9%, the coating produced thus has high uniformity, fine, good, good contact strength, porosity lower-level strengths.
