Electrostatic hazards in industrial production and related typical industries 2020-10-31
Electrostatic discharge (ESD) is defined as the discharge (current of electrons) to or from the charge (insufficient or surplus of electrons) that has been electrostatically (fixed). The charge is stable under two conditions: When it is trapped in a conductive but electrically insulating object. If an electrically insulated conductor (screwdriver) with a sufficiently high electric charge is close to an integrated circuit (IC) with an opposite electric potential, the electric charge will cross over and cause electrostatic discharge (ESD). The electrostatic charge generated by the object due to friction, peeling, electrostatic induction, etc., after a long time accumulation, the potential difference between the charged objects is so large that it may reach the breakdown field strength to a certain extent, and the instant discharge occurs. In industrial production, static electricity may be generated with various operations. Such as raw material feeding, mixing, finished product conveying, sub-packing, etc. If static electricity accumulates to a dangerous level, electrostatic discharge will occur, which may cause electric shock to people in the lighter case, and may ignite the surrounding flammable materials in the severe case, resulting in fire or explosion accidents.
