1, the powder resistivity powder resistivity 1010 ~ 1016 ohm / cm is preferable, Laiwu spraying equipment, low resistivity is easy to produce powder was dispersed, the resistivity is too high will affect the coating thickness. 2, dusting the amount of spraying the beginning, the amount of powder size has some influence on the film thickness, a small amount of general dusting, deposition rate. Dusting the amount of the general control of 50 g / min to 1000 g / min range. 3, powder and air mixture velocity and velocity gradient than the velocity gradient at the outlet of an air gun powder mixture and spraying distance, spraying within a certain time, with increasing thickness of the coating will decrease gradient. 4. Spraying distance spraying distance is one of the main parameters controlling the film thickness of the general control of the workpiece at a distance of 10 to 25 cm, and more from the gun form determined .5 time and spraying spraying spraying time voltage, spraying distance, spraying amount of a few Item parameter is the interaction time increases when spraying and large, the impact spraying voltage limit is reduced to a thickness of spray distance. With the increase of time dusting, dusting the amount of influence on the thickness of the growth rate is significantly reduced. 4) water dispersible powder coating the powder coating is an aqueous dispersion of powder coating with a stable aqueous dispersion medium, it combines the advantages of water-based paints and powder coatings, can be used in the process include immersion, brushing, spraying, electrostatic painting in all within conventional means. 5) powder electrophoretic coating which is fully mechanized and product powder coating and current painting, both both features. The basic principle is, automatic spraying equipment, electrophoresis resin dispersion containing an aqueous solution of the powder particles (General requirements 40μm or less) among the aqueous electrophoresis resin as the carrier film material powder particles, the powder particles are electrically charged, In the DC field electrophoretic deposition film. It is suitable for construction of the complex shape of the workpiece. Powder size, powder and air mixture velocity gradient. (1) Since the painting equipment is part of a dedicated special equipment, it is necessary to open and close the person responsible for the implementation and operation of the tour. (2) The design should consider the elimination of static electricity. Because the spray booth exhaust filtration system to filter material, mostly chemical products, to the wind and dust discharge in the process of filtering material will gather a lot of dust, the fan in the power down due to friction will produce more static electricity discharge phenomena, such as No static elimination device easily cause fires and explosions. Outdoor Dust duct if the building exceeds the height of lightning protection should also be considered. (3) in the design of the selection of the spray booth lighting fixtures, switches must be explosion-proof, fittings spraying equipment, are dangerous in the open. (4) be sure to use dust exhaust fan proof fans, taking also into account fan noise can not be exceeded. (5) meet the technical requirements under the premise as far as possible to choose affordable type to the exhaust fan, and to ask for the amount of wind turbines to the wind than the exhaust air volume of 10%, a slight positive pressure to ensure the paint room. (6) in the production of the installation according to the design requirements to make sure to avoid tamper drawings, paint the room in order to ensure quality of the installation. (7) to the exhaust system of filters and purifiers mist to be cleaned regularly to prevent the system operating environment damage. We must establish and improve related maintenance system, and let someone responsible. (8) Dry spray booth filters down solid waste and wet paint room filter down waste water must go through the proper process, to avoid secondary pollution. Remove all dirt (such as oil, rust, scale, dirt, sand, slag, salt spots, etc.) on the metal surface and the use of chemical methods to generate a layer of non-metallic conversion coating will help improve corrosion resistance of the workpiece collectively processing a metal surface treatment. Surface treatment is a major step electrophoretic coating. The quality of the surface treatment, a direct impact on the quality of life after electrophoretic coating film and the workpiece, it is necessary to attach great importance. First, the purpose of surface treatment before painting is coated on the surface to remove grease, oil, corrosion products, residual impurities, etc., fence spraying equipment, and to give the surface a certain chemical, physical characteristics, in order to increase adhesion of paint layers, increasing It is a protective and decorative coating material. The importance of surface treatment before painting is to provide a cleaning of painted surfaces to improve adhesion of the paint coating, the chemical conversion coating layer of non-conductive non-metallic generated to be improved corrosion resistance of the coating (increase more than double) Second, the classification of surface treatment before painting 1. Press the classification mechanical treatment method (manual method, power tools, Flame, sand blasting, shot blasting); chemical method (degreasing, descaling, surface conditioning, phosphating, passivation). 2. Press the handle classified material metal material (steel materials, non-ferrous materials); non-metallic materials (plastic, wood, cement).
