Electrostatic hazard and anti-static packaging
The cause of static electricity, the accumulation of static electricity and the danger of discharge to sensitive products, describes the electrostatic sensitivity of certain electronic and military products. A more detailed analysis of the principle of anti-static packaging. Through the analysis of the status quo of anti-static packaging technology, the author believes that decisive measures should be taken to enforce the electrostatic protection technology. It is recommended to strengthen the testing and research on electrostatic hazards. From the combination of theory and practice, deepen the understanding of electrostatic hazards and formulate corresponding technical standards as soon as possible.
1 Electrostatic accumulation and electrostatic discharge
When two substances rub against each other, the one that easily loses electrons is positively charged, and the one that easily obtains electrons is negatively charged. These two independent positive and negative charges are the static electricity (ie, static charge) that people usually refer to. In addition to friction, the induction of an electric or electromagnetic field is also an important cause of static electricity generation.
Static electricity can accumulate, that is, the more electrons that are lost, the more positive charges are accumulated; the more electrons are obtained, the more negative charges are accumulated.
