The winter weather is very dry, and the materials used by the photo machine are mostly paper, and the down jackets we wear are also chemical fiber fabrics, it is easy to produce static electricity, static electricity is very harmful to electronic components, it does not need to say much, it will affect the quality of the spray painting, and the heavy photo machine may burn the spray head and the circuit board. So how to eliminate static electricity on the photo machine?

　　1The choice of light box cloth: the surface roughness of light box cloth directly affects the generation of static electricity, try to chooseCaCO3 Light box cloth with low content and smooth surface.

　　2Be sure to take the photo machine ground grounding problem seriously, the correct way is:0.5Square meters of copper plate must be welded4Square millimeter copper wire buried in1.5Rice ground in wet soil below, and pour well salt water. Ground wire use the whole line, do not have a joint, and good contact with the machine.

　　3The use of ink with higher viscosity, the antistatic effect will be better, the principle is that the greater the weight of the photo machine ink drop, the smaller the electrostatic effect, but the impact of too high viscosity on the nozzle piezoelectric crystal is still to be explored.

　　4The humidity around the photo machine is reached40～60%Relative humidity, so, fromPVCThe static electricity generated by the friction of the light box cloth will also be transmitted from the air, and will not affect the ink droplets on the nozzle. The standard for purchasing an industrial humidifier is not less than an hour4Liters of water consumption, if the ventilation is good, try to choose6l/Hours of water consumption of the humidifier. In addition, some customers use spray guns and compressed air homemade humidifiers are also good.

　　5The temperature in the working area where the photo machine is placed is maintained15-25Between degrees Celsius, and try to keep the indoor temperature constant, in the operation room air exchange, pay attention to changes in temperature and humidity.

　　6Some customers use photo machine static brush to solve static electricity is also recommended.

　　The human body itself carries a lot of static electricity, which is easy to burn some precision electronic components inside the photo machine, the static electricity of the human body should also be eliminated, do not use the hand directly contact the photo machine, to avoid the static electricity generated by the human body affecting the work of the photo machine;Use tap water to wash your hands first, or touch other metal objects with your hands to eliminate body static electricity.
