Whenever winter comes, we have to consider a problem - static electricity. You may have this feeling at ordinary times. There is a sizzling sound when you take off your clothes, and you are suddenly electrocuted when you come into contact with metal objects or the human body.
Not only people are disturbed by static electricity, but digital printing machines are no exception. It may affect the printing quality and cause printing ink breakage, ghosting, misalignment and other problems. So how should digital printing machines prevent static electricity interference in winter? Take notes below!
1. Correct grounding wire
Use the ground wire to drain the static electricity generated by the equipment in a timely manner. The correct grounding wire method is as follows:
1. Use 3 pieces of galvanized angle steel (or φ32mm² round steel) larger than 40*40mm and drive them into the ground to a depth of not less than 2 meters. The distance between each piece should not be less than 1 meter. Then use galvanized flat steel (50mm*5mm) to drive these 3 pieces into the ground. Weld together firmly and open a φ8mm hole at the end.
2. The distance between the ground body and the building should not be less than 2 meters.
3. Use insulated copper wire larger than φ6mm² as the lead. One end is fixed with the grounding body with M8 screws, and the other end is connected to the equipment grounding lead.
2. Humidity control
In winter, heating or air conditioning is usually turned on indoors, which can easily increase the dryness of the room. The optimal working environment humidity of digital printing machines is 35%-65%. At this time, it is recommended that users turn on the humidifier to increase the air humidity when turning on the air conditioner.
3. Control printing speed
Different printing materials do not mean faster printing speed is better. The faster the printing speed, the higher the probability of static electricity in the digital printing machine. Therefore, everyone should choose a suitable printing mode when printing to prevent excessive static electricity.
The above are some ways to prevent excessive static electricity in digital printing machines. It is necessary to eliminate static electricity in advance so that the digital printing machine can always be in the best working condition and create more benefits.
