　　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.

　　Coating equipment can independently complete the entire process of emulsification, dispersion, grinding, refinement, cooling, filtration, vacuum automatic suction, and semi-automatic filling.

　　The coating equipment adopts a process flow of liquid metering, high shear emulsification dispersion, vacuum suction, vacuum defoaming, and semi-automatic filling, with one step from feeding to discharging the finished product.

　　Operating Procedures for Coating Equipment

　　（1） Equipment operators must be proficient in the construction, performance, operation, and maintenance methods of various machinery, and be responsible for their use by designated personnel.

　　（2） When operating woodworking machinery, it is necessary to wear work clothes, tie the cuffs tightly, and female comrades must wear work hats with braids placed inside; Do not wear gloves, scarves, etc. during operation.

　　（3） Before the machinery starts working, it must be tested and all components must operate normally before it can start working. Attention: If one or two ignition attempts fail; Okay, turn on the combustion fan for a while to exhaust the gas in the furnace before the second test run.

　　（4） The shafts, chains, pulleys, belts, and other moving parts on the equipment should be equipped with protective covers and plates.

　　（5） If there is any abnormal situation or other malfunction during mechanical operation, the power should be immediately cut off and the vehicle should be stopped for maintenance.

　　（6） The equipment is surrounded by flammable materials, and smoking and open flames should be strictly prohibited.

　　（7） When debugging and maintaining equipment, the main power supply must be cut off.
