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 static 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 personnel in the lighter case, and may ignite the surrounding flammable substances in the severe case, resulting in fire or explosion accidents.
As long as there is static electricity in the environment, it will cause harm to the product or even personnel. Generally, one of the two types of air ionization is used to dissipate static charge-α or corona. Over the years, corona has become the standard, and most organizations are familiar with it.
What is the life expectancy of static control equipment?
If the charged paper does not touch the fiber, the static control device will work for millions of cycles. Electrostatic technology recommends that the distance between the tip of the fiber and the charged paper is 2mm to 7mm.
According to medical experts, static electricity in the human body can cause a certain degree of harm. Static electricity generated by human interference can change the normal surface potential difference of the human body, change the influence of cardiac electrophysiology on the normal process of electrocardiogram, and will not interfere with normal conduction.
After using the ionization blower for a long time, the release of ions will decrease and the ion concentration will become smaller. Don't worry, this is normal. Due to the adsorption of dust, the discharge will not be obvious, which will greatly reduce the efficiency of static electricity removal.
