Currently, there are two basic methods for controlling static electricity:
1. The equipment is well grounded "but it cannot effectively eliminate static electricity on the material". The grounding of the machine is the most basic requirement at present. ① Good grounding allows the machine to operate efficiently without other problems caused by static electricity. However, when producing materials with static electricity, the static electricity on the materials can be conducted away when the grounding is done, but the effect is not significant. If the value of static electricity is as high as tens of thousands of volts, it is basically ineffective. If the ground can completely eliminate static electricity, there will be no static eliminator.
2. Use a static eliminator "can effectively neutralize the static electricity on the surface of the material". Use static eliminator: High-voltage static eliminator ionizes air molecules to free electrons from oxygen molecules, thereby generating negatively charged electrons and positively charged oxygen ions. If the material is positively charged, it can be neutralized by negatively charged electrons; conversely, if the material is negatively charged, it can be neutralized by positively charged oxygen ions. This method can maximize the elimination of static electricity in the production process and is currently the most desirable method for screen printing.
