The coating production line is mainly used for the surface treatment of metal and plastic parts such as household appliances, automobiles, motorcycles, steel-wood furniture, construction hardware tools, and instrument housings. Coating systems mainly include powder coating systems, automatic spraying systems, industrial stand-alone spraying equipment, and automotive special spraying equipment; powder and liquid spraying line equipment mainly include pre-treatment production lines, water curtain spray booths, automatic powder spraying devices, powder spray Robots, drying tunnels, drying rooms, automatic spraying devices, hanging material conveying equipment, etc. can be customized according to customer requirements. Main features of coating production line:
1. High production capacity, high degree of automation, saving human resources 2. Adopting multi-layer hanging bars, strong conveying system and stable quality 3. Large drying room, one more rotary baking to improve production efficiency 4. Fuel and gas hot air circulation, saving energy, Uniform temperature 5. Different workpieces can choose different speeds 6. Reduce costs and save more than 60% of paint 7. Easy operation and simple troubleshooting 8. Adopt full dust-proof and isolation, air supply design has high rate and safety Manual simple process and automatic pre-treatment process, the latter is divided into two types of automatic spraying and automatic dipping spraying. The workpiece must be surface treated to remove oil and rust before dusting. Many chemicals are used in this section, mainly including rust remover, oil remover, surface adjuster, phosphating agent and so on.
In the pre-treatment section or workshop of the coating production line, the first thing to pay attention to is to formulate the necessary purchasing, transportation, storage and use systems for strong acids and alkalis, to provide workers with the necessary protective clothing, safe and reliable containment, transportation, and equipment, and Develop emergency measures and rescue measures in case of an accident.
Secondly, in the pre-treatment section of the coating production line, due to the existence of a certain amount of three waste materials such as exhaust gas and waste liquid, in terms of environmental protection measures, it is necessary to configure exhaust gas exhaust, liquid discharge and three waste treatment devices.
The process of the coating production line is mainly divided into: pre-treatment, powder coating, heating and curing; its operation process: grinding manual dust removal-top piece-electrostatic dust removal-preheating-manual spraying-heat curing (-UV light curing) －Cooling- Lower part coating production line technical description: Process flow: grinding manual dust removal-upper part-electrostatic dust removal-preheating-automatic electrostatic spraying (primer)-heat curing-cooling-electrostatic dust removal-automatic electrostatic spraying (top paint) －UV light solid-cooling-next piece
