1, the resistivity of the powder in the powder resistivity of 1010 - 1016 ohm / cm is preferable, easy to produce low resistivity redispersible powder, 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 the powder particles (General requirements 40μm or less), and an aqueous solution containing dispersed among the electrophoretic resin, an aqueous electrophoresis resin as the carrier Hebei painting, film-forming 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. 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 the removal of surface treatment before painting is coated on the surface of grease, oil, corrosion products, residual impurities, etc., and to give the surface a certain chemical, physical characteristics, in order to increase adhesion of paint layers, increase to be coated protective and decorative. 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). General Booth by way of heating can be divided into coal-fired paint room, electric heating paint room, far infrared paint room, paint room gas. First, energy efficient carbon fiber infrared heating tube electric conversion rate greater than 95%, and the total pressure clean paint spray booth, than the average 30% energy saving heating pipes, more suitable for modern painting's energy efficiency, avoid the common electric heating, oil type paint room energy consumption, coating equipment lines, higher operating costs drawbacks, is the direction of development of the paint industry. Second, safety and environmental protection, comprehensive use of environmentally friendly technology to improve the operating environment, the heating system does not require high current start, avoiding rapid cooling Fuel paint room three existing security risks, paint effect: carbon fiber, far infrared quartz tube using its own far-infrared radiation heating, (rather than by convection conduction) while avoiding air circulation to finish the formation of secondary pollution, so the paint surface cleaner to improve paint quality. Fourth, economical and practical, painting the powder room, the design breaks the traditional idea of ??the paint room, reducing the heating pipes and mechanical systems, significantly reducing failure risks, and to avoid the common Booth large energy disadvantages, low operating costs, energy-saving, easy to use is the last word, but as many outstanding 4S repair shop of choice for manufacturers of products V. electric heating and oil heating energy difference between the electric heating system security technology specifically refers to: 1. The coating drying room electrical equipment shall be reliable measures to prevent electrical shorting of the shell must be grounded. 2. The coating drying room electrical equipment should meet the requirements of fire and explosion due temperature electrical wiring insulation.
