The leakage method adopts humidification measures and antistatic additives

The leakage method adopts humidification measures and antistatic additives to promote the dissipation of electrostatic charges from the insulator. This method is called the leakage method. (1) Humidification. Humidification is to increase the humidity of the air. Humidity has a great effect on static leakage. With increased humidity, the surface resistance of the insulator is greatly reduced, the conductivity is enhanced, and the leakage of static electricity is accelerated. If the relative humidity of the air is maintained at about 70%, a large amount of static electricity can be prevented. (2) Add antistatic additives. Antistatic additives are special auxiliary agents. Some additives can increase the hygroscopicity or ionicity of the materials after adding them to the insulating material that generates static electricity, thereby enhancing the conductivity and accelerating the leakage of static electricity. (3) Use conductive materials or paper insulation materials. For mechanical parts that are prone to static electricity, use conductive materials as much as possible. The inner layer of a container made of insulating material is lined with a conductive layer or a metal network and grounded; the use of conductive rubber instead of ordinary rubber will accelerate the leakage of electrostatic charges.
Neutralization method Neutralization method is an important measure to eliminate static electricity. The electrostatic neutralization method is to try to generate charged ions in a place where electrostatic charges are dense, and neutralize the electrostatic charges there. Static neutralization can be used to eliminate static electricity on insulators. Can use induction neutralizer, high voltage neutralizer, radiation neutralizer and other devices to eliminate static hazards.
The humidification mentioned earlier in the process control method is a measure to eliminate the danger of static electricity from the process. However, humidification does not control the generation of static electricity, but accelerates the leakage of electrostatic charges and prevents the accumulation of electrostatic charges to a dangerous level. In the process, appropriate measures can also be taken to limit the generation of static electricity and control the accumulation of electrostatic charges. For example: use gear drive instead of belt drive to reduce friction; reduce the flow rate of liquid, gas or dust material to limit the generation of static electricity; maintain the normal tensile force of the drive belt to prevent slipping; the pipe filled with liquid goes to the bottom of the container or close to the sidewall Avoid liquid shocks and splashes. There are other measures that do not fall into the above four measures. For example, in order to prevent the harm caused by static electricity on the human body, workers can wear antistatic work clothes and work shoes, and measures such as ventilation and dust removal are also helpful to prevent the harm of static electricity.
