Solve the basic principle of anti-static protection
Anti-static experts point out that static electricity is generated by contact, separation and friction between objects. Any extrusion, cutting, handling, stirring, filtering, walking, standing, undressing, etc. in the production process will generate static electricity. It can be said that static electricity can be said. Static electricity is everywhere in our daily production and life. There may be static electricity of up to several thousand volts to tens of thousands of volts in or around ourselves. These static electricity can sometimes cause harm to our body and cause losses to our production, especially for some static-sensitive components. It is possible to directly lose normal working performance, so electrostatic protection of sensitive components is particularly important.
In order to avoid the harm caused by static electricity, we must eliminate static electricity. The methods to eliminate static electricity are physical and chemical methods. One is to eliminate static electricity by grounding, the other is to install static eliminator, the third is to increase the electrostatic agent, and the fourth is to rely on the high electrostatic agent. Shield to achieve the effect of eliminating static electricity. The basic principle is:
1. Static electricity dissipation, static electricity dissipation and leakage are methods for quickly dissipating and leaking static electricity generated in the production environment and various operating procedures to prevent electrostatic hazards. They are usually realized by grounding or anti-static floor materials.
2, electrostatic shielding, it is usually used to shield the electrostatic field generated by the high-voltage power supply and some circuits sensitive to the static electrode to prevent the danger of static electricity.
3, humidification, it is mainly by increasing the surface conductivity of non-conducting materials, so that the static charge stored in the volume of the object can be leaked faster, in order to achieve the control of static electricity, humidity generally needs to remain above 60% -70% In order to achieve anti-static effects.
4, static neutralization, in some occasions, when it is inconvenient to use ESD protective materials, or must drop some high-insulation and easy to generate static electricity when storing the workbench or process line, in order to ensure product quality, it is necessary to take static electricity to the operating environment Neutralization measures. Static neutralization is achieved by means of an ionic static eliminator or an inductive electrostatic brush.
