Design coating line, the first from the design task book (or tenders), or directly from the user and coating materials manufacturers, and other units to be coated traits (material, shape and size) and the amount of processing requirements coating coating technology relevant design data performance characteristics of coating materials and the like; then the above coating pre-treatment target selection process to determine the technical requirements of the former, pre-treatment process; taking painting before and after the workshop process layout and design processes and logistics elements. Device designers to design various elements carried out based on the most advanced and reliable cost-effective design. Paint pre-treatment apparatus generally includes a process chamber (eg, spray chamber, before processing channels, blasting room - sprinkler system), the processing tank (eg dip tank, spray tank, spare slots, etc.), pumps and piping, exhaust air system and ancillary auxiliary devices. Paint pre-treatment of the various elements of the design of the most critical item is the pre-treatment process and the relevant parameters, followed by treatment before painting. The elimination of all kinds of oil before painting was painted on the surface (such as lubricating oil, emulsion, anti-rust oil, grease, perspiration, etc.) and dust, the cleaning process to be coated is clean coating pre-treatment process is essential process; a clean surface to be painted (if) what kind of chemical treatment (or conversion coating process) or mechanical processing (such as shot blasting processing, etc.), according to the substrate to be coated and surface state, painting process requirements choose. 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 layer coating powder room, 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). (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 building height exceeds painting whirlwind recovery, lightning protection should also be considered. (3) in the design of the selection of the spray booth lighting fixtures, switches must be explosion-proof to avoid danger in the open. (4) be sure to use dust exhaust fan proof fans dip coating equipment, 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 exhaust fan to painting, also asked 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.
