powder coating the main coating method is electrostatic powder coating method, the use of static electricity is high-voltage static electricity, voltage in 30 to 100kv, the voltage is very high, but the current is very smallThe current that usually damages human organs is 5mA, while the current of the spray gun is 0.7mA, which is safe for the human bodySome people are sensitive to high-voltage electrostatic induction, when touched on the body has a clear stimulating effect, frightened will cause secondary disasters and accidentsIn order to avoid and prevent such accidents, we should pay attention to the problemshould use a high-pressure generator installed in the body of the spray gun when sprayingIt is not appropriate to use high-voltage cable to connect the gun and the high-voltage generator gun, if you must use this high-voltage cable spray gun, we must take measures to prevent cable leakage and discharge problems, so as not to cause accidentsthe voltage used should be controlled below 9wv, more than this voltage will be detrimental to the human body's home resistanceIn addition, the short-circuit current should be controlled below 0.7?Ain order to eliminate static charge as soon as possible, manual spraying, spray gun immediately after use contact with ground conductors, timely release of residual charge, while the human body and the ground do not insulate, timely elimination of the body chargethe distance between the coated object and the spray gun should not be too close, to maintain more than 10cm, to prevent short circuit to produce electrical sparks
