Use anti-static metal hose
This is the most direct and effective method. The metal hose itself has good conductivity and can quickly conduct static charge into the ground. In particular, the copper wire metal hose, the copper wire mesh covering its surface has excellent protection against static electricity. Although the plastic sandwich metal hose has a slightly poor anti-static ability. But it can also meet the use requirements in certain specific occasions.
Add conductive agent and antistatic agent
Adding conductive agent to the hose material can make the plastic molecules conductive, which helps to eliminate static charge. The antistatic agent achieves the anti-static effect by absorbing moisture in the humid air. Both methods can effectively reduce the resistance value of the hose surface and improve the discharge efficiency of the charge.
Use a hose with a metal spiral wire
This method uses the conductivity of the metal spiral wire to conduct static charge into the ground through the spiral wire. At the same time, the spacing and overlap of the spiral wire need to be controlled within a certain range to ensure its effectiveness.
Grounding measures
Grounding is one of the important measures to eliminate static electricity in pipelines. By installing a grounding wire and connecting the metal pipe to the ground, static charge can be discharged to the earth. The grounding wire should be evenly distributed throughout the pipeline system to ensure good contact with the pipeline. At the same time, the grounding block is also an effective grounding method. It can be connected to the ground wire to further ensure effective discharge of static charges.
