The role of dust-free clothing and anti-static wrist strap in the workshop
1. Wireless electrostatic wristband: It is based on the physical principle of (static voltage balance). According to the principle of "static engineering", static electricity is developed by the principle of pushing between the ions. The characteristic of pushing from the high potential pushes the electrostatic ions of the human body to the drought body design (collection area), and the [equivalent amount of opposite charge]-skin effect will be carried on the front and back surfaces of the conductive plate through [charge induction principle], Because the ion exchanger <utilize its low free energy characteristics> is built in, it can easily provide the same amount of heterogeneous charge of the introduced electrostatic ions for neutralization, so it can achieve the effect of electrostatic discharge, and there is a screw on the outside of the machine. , Connected to the internal conductor loop.
(1) It can be used as a result of improper personnel touching the high static power supply, causing a large amount of static charge to be introduced instantly. When the ion neutralization is not completed, the ion neutralization can be provided by the external air water molecules with the screw (it is for the Corona discharge effect), To effectively eliminate static electricity, and achieve the ultimate goal of electrostatic discharge (static voltage balance).
(2) This screw can be used for the potential zeroing function (just touch the screw to ground).
(3) Can be used as a loop detection terminal.
2. Wired wrist strap: It is the most basic antistatic equipment and the most commonly used product on the production line. It is not only very convenient in erection and operation, but also the most economical in terms of price. The strap and the ground wire discharge the static electricity on the human body to the ground. Therefore, the wrist strap must be in direct contact with the skin during use. The ground wire must also be directly grounded, and the ground wire must be unobstructed for maximum effectiveness.
Anti-static wrist strap electrostatic ring is a device that is worn on the wrist of the human body and discharges the accumulated electrostatic charge of the human body. It is divided into wired and wireless types, and has a mixed ring of metal rings and elastic conductive wires. This product belongs to the anti-static wrist strap closure adjustment cable type, which can effectively protect the zero resistance parts from the interference of static electricity and discharge the static electricity of the human body. It is composed of anti-static elastic band, movable snap button, spring cord, protective resistance and chuck. The inner layer of the elastic band is woven with anti-static yarn, and the outer layer is woven with ordinary yarn. The principle of the anti-static wired wrist strap is to conduct the static electricity of the human body to the ground through the wrist strap and the grounding wire. When using the wristband, contact the skin and ensure that the grounding wire is directly grounded, so that it can maximize its effectiveness. Wearing this anti-static wrist strap, it can safely remove the static electricity generated in the human body within 0.1 seconds. The grounded wrist strap is the most basic and most commonly used anti-static equipment.
