Embodiment Construction

[0027] Pre-treatment must be carried out before painting, and the necessary overall inspection shall be carried out in the pre-treatment, and partial rest shall be carried out according to the process. The present invention is formulated according to GB11373 and according to reality.

[0028] A method for spraying a workpiece, comprising the steps of:

[0029] (1) Workpiece protection treatment: all internal threads are plugged with studs, and external threads are shielded and protected for parts that do not need to be sprayed; threaded holes of the oil injection port are blocked with grease nozzles; non-painted end faces and partial planes are shielded and protected; surfaces are not allowed On the workpiece with glue remaining, use a special cover plate to cover it with a strong magnet; the instrument or liquid crystal panel accessories cannot use magnets; the oil inlet and oil outlet of the hydraulic system components are sealed with a cover plate;

[0030] (2) Handling of...

Abstract

The invention belongs to the technical field of paint spraying, and provides a paint spraying method for a workpiece. The paint spraying method aims at solving the problems that when an existing paint spraying technology is used in the paint spraying process, pits are generated, the paint spraying time is too long, consequently, the paint spraying percent of pass is low, cost is high, the mechanical performance is poor, and the corrosion resistance is poor. The paint spraying method comprises the steps of workpiece protection, workpiece hanging and placing, washing, primer mixing and spraying and finishing paint spraying. Compared with a traditional process, the environment protection effect is remarkable, and the specialization level of paint spraying is greatly improved. Compared with manual spraying gun operation, the labor intensity of operators is relieved; the production cost is reduced, the paint spraying quality is guaranteed, and paint is saved; and the excellent mechanical performance is achieved. Excellent corrosion resistance is achieved, and the appearance is attractive. A paint film is full, the gloss is gorgeous and soft, and an aesthetic feeling is provided for people.

Description

technical field [0001] The invention belongs to the technical field of painting, and in particular relates to a method for painting a workpiece. Background technique [0002] Spray paint is to cover the surface of the products and semi-finished products after passing the inspection, and play the role of anti-rust, anti-corrosion, beautiful and beautiful. Pre-treatment must be carried out before painting, and the necessary overall inspection shall be carried out in the pre-treatment, and partial rest shall be carried out according to the process. [0003] Spray paint and spray plastic are the main ways of industrial surface decoration today. Compared with spray paint, spray paint has the advantages of good leveling, repairability, good flexibility, rich decoration, high hardness, high efficiency, and easy to overcome substrate defects. Therefore, has been more and more widely used. Usually, the method of painting is: spray primer, first topcoat, second topcoat, and transpar...
