What are the requirements for the use of powder spraying equipment?

1. Powder spraying line equipment is a coating process that charges the spraying medium, i.e. powder, and makes it adhere to the grounded workpiece. The adhesion of powder to the workpiece mainly depends on the process of heating, curing and leveling of the workpiece adsorbed with powder to form a complete film. The equipment is mainly composed of moisture drying furnace, powder curing furnace, hanging conveyor chain, double station automatic powder spraying room, automatic powder spraying device, heating device, electric control system, etc.

2. Before using the powder spraying line equipment, turn on the drying furnace for preheating and turn on the exhaust fan of the paint booth.

3. Operators must wear anti-static shoes or conductive shoes, and the resistance value shall not be greater than 1.5105 ohms.

4. Before the operation of powder spraying line equipment, check whether all equipment, such as circuit connector, spray gun installation, grounding wire, etc. are intact.

5. Confirm that all metal parts of the paint booth: exhaust pipe, air supply pipe and pipeline conveying combustible liquid have been reliably grounded.

6. Operators must receive technical training before taking the post.

7. The distance between the high-voltage cable and other power lines shall be kept above 500mm to prevent breakdown and discharge. 8. Turn all switches of the high-voltage generator to the "off" position, and then turn on the main power switch on the high-voltage generator: first turn on the 220 volt power switch, turn on the 380 volt power switch after the green light is on for 30 minutes, and then start the high-voltage button. After the red light is on, gradually increase the voltage to 80-90 kV.

9. The distance between the spray cup and the workpiece shall not be less than 150mm.
