Description :

　　Environmental protection measures for coating equipment

　　(1) Appropriate masks and gas masks must be worn during work, and good ventilation measures must be taken.

　　(2) The parts with high solvent evaporation must be equipped with gas collection devices to prevent the diffusion of toxic gases.

　　Process Design

　　To achieve a relatively high utilization rate of painting equipment, it is necessary to establish a reasonable painting production line. Firstly, the production plan should be determined, the process design and scheme planning should be improved, and then the equipment design, manufacturing and installation can be carried out. Therefore, process design and scheme planning are the foundation for establishing a production line, and a correct and reasonable process will have a decisive impact on production operations and product quality.

　　The content of process design mainly includes: pre-treatment methods for workpiece surfaces, painting methods, coating performance, spraying environment, process planning, etc.

　　processing equipment

　　The purpose of pretreatment is to remove foreign objects such as oxide scale, rust spots, grease, etc. carried by the coated parts, provide a good substrate suitable for coating requirements, such as phosphating, oxidation, passivation, to ensure that the coating has good anti-corrosion and decorative properties. Pre treatment equipment is mainly divided into physical and chemical formulas.

　　1. Physical formula:

　　① Remove impurities attached to the surface of the steel plate and use a diluent to remove grease and other dirt.

　　② If there are sulfates or corrosive salts, they should be washed with clean water and dried with compressed air.

　　③ On the steel plate pretreatment production line, the oxide scale, rust and other impurities are removed by shot blasting or sandblasting rust removal methods, and then the steel surface is cleaned with a vacuum cleaner or purified compressed air.

　　2. Chemical formula:

　　1. Immersion type, spray type, immersion spray combined type, spray immersion spray combined type.

　　2. Acid washing, phosphating slag removal, and oil-water separation devices are key systems. Phosphating slag removal includes commonly used methods such as sedimentation, rotary liquid separation, inclined plate sedimentation, bag filtration, and plate and frame filter press.

　　3. Oil water separation mainly includes adsorption method, ultrafiltration method, hot oil separation method, and centrifugation method.

　　Painting equipment is divided into processing functions

　　1. Pre processing

　　For example: sandblasting machine, acid washing equipment, phosphating equipment, electrophoresis, etc

　　2. Baking paint, drying paint, and conveying

　　Such as: baked paint tunnel line, baked paint box, baked paint room, drying strong cold, positive pressure dust-free room, belt conveyor line, hanging line, floor line, multi-layer paint drying rack, etc

　　3. Polishing

　　Such as: ordinary sanding machine, vertical and horizontal sanding machine, primer sanding machine, elevated sanding machine, irregular sanding machine, air drum sanding, Chiba wheel sanding, sponge wheel sanding, disc sanding machine, push table sanding machine, etc

　　4. Dust removal

　　For example: dust removal machine, bag vacuum cleaner, electrostatic precipitator, double-sided dust removal machine, belt conveyor dust removal machine, etc

　　5. Spray painting, powder coating

　　The main equipment includes: spray painting, airless spray painting, electrostatic spray painting equipment, electrostatic powder spraying equipment, etc

　　6. Roll coating, spray coating

　　For example: ordinary roller coating machine, semi precision roller coating machine, fully precision roller coating machine, putty machine, flattening and color changing machine, screen spraying machine, etc

　　Introduction to Painting Equipment

　　Coating refers to the process of processing products made from materials such as metal, plastic, wood, etc., with a protective or decorative layer covering the surface. With the development of industrial technology, the development of coating technology and equipment in China has gone through a process from manual to mechanical equipment to automatic production lines. The coating process generally includes pre-treatment, polishing → coating → leveling → drying or curing → three waste treatment. Painting equipment is the mechanical equipment used to complete these painting processes.

　　The painting equipment industry truly originated in the 1950s when Soviet technology was introduced. Starting from 60 years ago, due to the development of light industry, automated production lines first appeared in the bicycle manufacturing industry. During this period, the main task of China's coating industry was still anti-corrosion. But with the development of China's economy and the development of foreign painting technology, through technology introduction and exchange with foreign technology, China's painting technology has begun to develop rapidly. In terms of automated production of painting, the promotion and application of electrostatic spraying and electrophoretic painting technology, the research and promotion of powder spraying technology, especially in the home appliance industry, daily hardware, steel furniture, aluminum components, electrical products, automotive industry and other fields, have made significant progress and significant development in painting equipment.
