Antistatic products work principle
Anti-static wrist strap: The anti-static wrist strap provides an effective static discharge channel from the human body to the ground. The grounding component is connected in series with a 1M ohm resistor to protect the human body and static sensitive components from damage. When wearing the bracelet, the bracelet should be in good contact with the skin, and the grease should not be applied to the belt. The bracelet should be tested daily to ensure good performance.
The anti-static wrist strap is grounded by a wire and iron clip by a 1MΩ resistor in the wire by a stainless steel case that is tightly attached to the wrist. The purpose is to discharge the static electricity on the human body at any time, and to prevent the spark generated by the rapid discharge, causing damage to the electrostatic sensitive device and functioning as an isolation. Broken wires or poor contact can make the electrostatic hand ring the same. The so-called wireless wristband actually does not discharge the static charge carried by the human body.
Anti-static clothing and anti-static shoes work
Anti-static clothing: Persons entering the anti-static area must wear anti-static clothing. The requirement is that the static voltage does not exceed 300V.
Anti-static clothing is made of special anti-static clean fabric. This fabric uses special polyester filaments to weave conductive fibers in the warp or weft direction. It has high-efficiency, permanent anti-static, dust-proof performance, thin and smooth, and clear texture.
A special overlocking machine is used in the process of making garments, which effectively reduces the generation of particles. The dust-free fastening tape avoids contamination of the environment by hair loss. Different styles are provided according to the level requirements, and conductive fibers are used to make the parts of the garment maintain electrical continuity; the sleeve tube is a unique double-layer structure, and the inner layer is made of conductive or anti-static rib to meet the requirements of high-level dust-free environment. .
Anti-static shoes are production plants in the microelectronics industry such as electronic semiconductor devices, electronic computers, electronic communication equipment, and integrated circuits. A work shoe worn by an advanced laboratory to reduce or eliminate static hazards. The anti-static shoes can guide static electricity from the human body to the earth, thereby eliminating static electricity of the human body, and at the same time effectively suppressing the dust generated by the walking of the person in the clean room. Suitable for pharmaceutical factories, food factories, electronics factory clean workshops, laboratories, etc. The anti-static shoes are made of bulk material PU or PVC material to make the sole, and the sole is made of anti-static anti-skid material, which can absorb sweat and deodorant, and can achieve anti-slip, anti-static and other functions, and is integrally formed with the upper, and then is strengthened on the line. It can effectively leak static electricity and form a complete anti-static system together with anti-static clothing.
