Eliminate static electricity from paper printing.
Install a static eliminator on the printing press to eliminate the static electricity of the paper by adjusting the voltage or high frequency. When the static electricity is not large, lower the voltage and high frequency; if the paper has a large static electricity, use high voltage or high frequency. When the speed is slow, the air temperature is maintained at 70-80%.
You can also use a comprehensive elimination method to eliminate the static electricity on the paper, that is, the effect of improving the temperature and moisture content of the paper and using a static eliminator will be better. When the paper is urgently used, the paper dryer can be used to hang and dry the static charged paper. When hanging and drying, pay attention to the coordination of machine speed and air humidity, that is, when the machine speed is fast, the relative temperature of the ambient air is controlled at 80-85%.
After printing on the cut paper, static electricity appears. You can use the "steam method" to quickly dry the paper to reduce the static electricity on the paper to complete the printing. Install anti-static equipment in the printing shop, adjust or maintain the temperature and humidity in the printing shop according to the strength of the paper static electricity. Use the paper drying method to dissipate static electricity from the paper.
It is necessary to control the length of the source to prevent the occurrence of printing static electricity. The paper with static electricity can be temporarily suspended and the inventory time should be appropriately extended. The temperature and humidity of the paper warehouse should be controlled to be within 18 ° C-20 ° C. The relative humidity of the air Grasp between 60-65%. Under this premise, it is beneficial to reduce or eliminate paper static electricity. You can also use the isotope discharge method: ionize various molecules in the air into ions. Because ions have different electrical properties, they become good conductors of electricity. When paper passes through the ion space, one part of the static electricity is neutralized, and the other The department was taken away by air ions, so that the purpose of eliminating static electricity was achieved.
