Description :

　　Requirements for the use of coating equipment

　　(1) Any process that uses toxic, toxic, or flammable substances should be placed in a separate factory or arranged in a specially separated area within the factory, and equipped with personal protective equipment and fire-fighting equipment.

　　(2) The passages in the workshop should be equipped with facilities to eliminate ventilation and prevent the spread of fire, such as automatic fire doors, fire and smoke barriers, water curtains, etc.

　　(3) When it is necessary to safely reach the work position above the equipment, a pedestrian bridge with protective railings and stairs should be installed. Anti slip flooring should be installed on the factory floor and pedestrian walkways.

　　(4) There should be no stacking of equipment, objects, or wires crossing the pedestrian walkway, and the width of the walkway should not be less than 1m

　　(5) A protective net must be laid below the assembly line walking above the work area to prevent objects from falling.

　　(6) Excess paint and waste paint should be isolated and stored in the paint warehouse.

　　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.

　　Characteristics of painting equipment

　　(1) Coating equipment cannot do without solvents, and many components need to be solvent resistant.

　　(2) Coatings are flammable and explosive materials, and many parts of equipment need to be treated with flame retardant and explosion-proof measures.

　　(3) The painting process requires precision and high equipment accuracy

　　(4) The equipment load is low and there are few heavy equipment.

　　(5) Painting equipment is relatively easy to plan assembly line production methods, saving labor.

　　(6) The running speed is relatively slow.
