2. Ventilation: During electrostatic spraying, air supply and exhaust should be maintained. The spraying equipment should not work when the air supply and exhaust are not turned on. After painting, the air supply and exhaust should last for 5 ~ 10 minutes and then be turned off.
Personal protection: Special conductive gloves should be worn during operation, and operators should wear anti-static clothing, not underwear made of silk, synthetic fiber and other materials that are easy to generate and accumulate static electricity.
4. Grounding: Enter the painting room and paint mixing room, touch and conduct electricity to eliminate static electricity carried by human body. Conductive substances of all metal materials in the painting room shall be grounded, and the grounding resistance shall be less than10Ω. It is also necessary to keep the track clean, ensure that there is water on the track, and ensure that the sprayed workpiece is in a good grounding state.
Verb (abbreviation of verb) Operation: During electrostatic spraying, don't let the high-voltage electrode at the top of the spray gun and its surrounding parts get close to or touch the sprayed object and grounding object. When painting, don't aim the spray gun at people, put your hands on the nozzle. When the spraying operation is interrupted or completed, the control power supply must be cut off first. After waiting for 5 seconds, the corona needle at the top of the spray gun should contact with the grounding wire or grounded metal object for more than 10 second to release the residual charge.
Intransitive verb cleaning: Turn off the power of electrostatic spray gun when cleaning. Nozzle should also be cleaned frequently during operation, and the coating attached to the nozzle will cause poor atomization and affect the electrostatic effect. Do not soak the gun body in solvent when cleaning. Hold the spray gun and wash it with a soft brush or rag dipped in solvent. Note that when the nozzle is blocked, it should be soaked in solvent first, and then blown with compressed air. Metal brushes are not allowed. When cleaning, the solvent can not exceed 80% of the container volume, and should be cleaned in a well-ventilated place.
