To prevent electrostatic hazards during the powder coating process, first try to prevent static electricity from being generated, and limit the static electricity that has been generated so as not to affect production, and secondly, the leakage or neutralization of electrostatic charges. Summarize several common methods to eliminate static electricity in the powder coating process. <br /> Reduce static electricity. < Br Reducing static electricity is usually to reduce friction and electrification. In transmission equipment, reduce the slippage of belts and other transmission parts. At the same time, Avoid overload operation, etc.
Electrostatic grounding can alleviate the static electricity of powder coating. <br /> The function of electrostatic grounding is to release the electric charge that may be accumulated on the conductor, make the conductor equal to the ground, and make the potential difference between the conductors to zero.
Temperature and humidity control slows down electrostatic spraying of powders. When the relative humidity of the air is above 65-70%, the resistivity is reduced. When the resistivity of the substance is less than 106Ω.cm, the accumulation of electrostatic charges can be prevented. Static electricity is least likely to accumulate, so you can purchase a suitable humidifier.
Filling the antistatic agent during the powder spraying process. <br /> The method of incorporating a substance with good conductive properties to reduce its resistivity. When the resistivity of the substance is less than 106Ω.cm, it can prevent the accumulation of electrostatic charges.
Static elimination method to eliminate the static electricity of powder spraying. <br /> Using an active static eliminator to ionize the air to eliminate the static electricity on the surface of the object. Generally, the ion air nozzle is used to solve the problem. The strong ionization ensures the rapid laminar flow to thoroughly clean the surface of the object.
