How to remove static electricity contained in electronic equipment
During the operation of laboratory instruments and meters, since the source of static electricity is friction or separation between objects, it is easy to generate static electricity, so these effects should be suppressed as much as possible. Static electricity can cause malfunctions or malfunctions of electronic equipment, causing electromagnetic interference; breakdown of integrated circuits and precision electronic components, or aging of components, reducing production yield. The most serious electrostatic discharge among electrostatic hazards causes fire and explosion of combustible materials.
Static electricity prevention method:
1. The method of adding conductive material to the object can be used, such as adding metal powder or carbon black to the object, using hydrophilic oil in chemical fiber or plastic, etc., which can effectively prevent static electricity.
2. The friction or separation between objects is the source of static electricity, so these effects should be suppressed as much as possible to prevent static electricity. If you do not use insulators that are easily charged, you should use materials that are difficult to generate static electricity for liquid pipeline transportation, dust air transportation, or plastic extrusion. 3. It can increase the humidity by adjusting the humidity device, sprinkling water, etc. to form a water-absorbing layer on the surface of the object to enhance conductivity and prevent static electricity. However, when using this method, the adverse effects of humidity on staff and equipment should be considered.
4. If there is still static electricity after the charge is leaked, the charged charge should be eliminated. Static electricity removal devices such as static electricity eliminators can be used.
5. The accumulation of electric charge can cause static electricity disaster, so to promote the leakage of electric charge, the most effective method is to ground. The metal conductor makes the generated charge quickly disappear to the earth, but the grounding method is not suitable for plastic, chemical fiber, petroleum and other insulation materials.
