1. When dipping, the paint in the paint barrel should be mixed evenly, and diluent should be added on time.
2. The parts which have been pickled and Phosphated shall be coated with primer on the same day (no more than 24 hours at most). If the time is too long, the rust should be removed from the beginning.
3. During the working process, the pressure of the air tank should be checked frequently. The dry-type transformer should be kept at 0.4-0.6mpa, and the water should be drained every day to ensure that the compressed air is dry.
4. During operation, it is necessary for the staff to take protective equipment. Fireworks are strictly prohibited in the workplace of dry-type transformer, and the paint should not be close to the fire source.
5. When spraying paint, the distance between the spray gun and the workpiece should be 150 ~ 200 mm; when spraying primer, the air pressure of the spray gun should be 25 × 104 ~ 34 × 104 Pa; when spraying the top coat, it should be 29 ~ 34 × 104 Pa; the eruption stroke should overlap 1 / 2 ~ 1 / 3, which should be adjusted according to the diameter of the spray gun and the size of the spray surface.
6. For the oil tank with putty on the surface, the putty ash after grinding shall be blown clean, and the primer shall be applied to dry before spraying the top coat.
7. The putty mixed evenly according to the proportion must be used within 10 minutes to end the dry-type transformer to avoid spoiling.
8. It is necessary to apply putty after the primer is dry.
9. Test the adhesion of each batch of new paint. The test method is as follows: spray the paint film on a sample plate. After the paint film is dry, the hand wallpaper knife will mark on the paint film. The horizontal grid distance is 1.5cm, and the lines are straight. The lines are more than 5. After the dry-type transformer is covered with the transparent tape, one end of the transparent tape is pulled up after 1-2 minutes.
