6 ways of generating static electricity
Static electricity has the characteristics of high voltage, low current, and short operating time. Electrostatic discharge causes electronic components to be broken down, which is a common and serious electrostatic hazard in the electronics industry. Static electricity is divided into hard breakdown and soft breakdown. Hard breakdown is a one-time breakdown or burning of electronic components, resulting in long-lasting failure of electronic components. Soft breakdown is a result of a decline in the performance of electronic components, which is difficult to detect before leaving the factory and causes hidden dangers. So what are the ways of generating static electricity?
There are six ways to generate static electricity:
1, friction and electricity. I believe that the small partners who have learned physics know that two objects will be rubbed together to generate electricity. This type of electricity is often found in daily life and production operations.
2. The molecular splits up and electricity. The deformation, fragmentation, fracture, etc. of the object will cause the neutral molecules to split and electrify, and sometimes even the sudden break and break, the discharge of Mars will occur.
3, static induction power. When a charged body moves closer to a neutral object, or a neutral object approaches a charged body, due to the electric field of the charged object, the neutral object has a charge opposite to that of the charged object at the end close to the charged object. At the other end, there is a charge of the same polarity as that of the charged object. This type of electrification is also common.
4. The ray ionization air is electrified. Insulators and air, under the irradiation of radioactive isotopes α, β, and γ rays, cause neutral molecules to ionize and electrify.
5. Electromagnetic induction starts. The lighting, power, and the like used in daily life and industrial production are powered by the principle of electromagnetic induction. The application of electrostatic technology is also a new technology that converts low-voltage electricity into high-voltage electricity using the principle of electromagnetic induction power generation.
6. The three-state change of matter starts to electrify. We all know that water is a conductor, and water becomes solid below 0 ° C. When water forms ice, ice is charged. When liquid water turns into water vapor, the water vapor is also charged. Water vapor is condensed into water droplets, snow or hail, etc., all of which are charged.
Static electricity is everywhere and there is nowhere to go. It is almost impossible to completely eliminate it. Static electricity is especially harmful to electronic components. Therefore, in the production operation, it is necessary to take some measures to control the static electricity so as not to cause harm, such as increasing the humidity of the environment, wearing anti-static gloves, anti-static shoes, anti-static clothing,esd wrist strap,esd heel strap,esd cap,shoes cover etc. when touching sensitive objects.
