What is the principle of antistatic tape?
What is the principle of anti-static tape? The anti-static agent in anti-static tape can effectively absorb the “moisture” in the appearance and air of the product. After the water is obtained, it can neutralize with static electricity, thus achieving anti-static effect. Antistatic tape is an antistatic agent added to the tape substrate or glue.
Before the film is blown, the antistatic agent is added and uniformly mixed and plasticized by the screw. This is relatively simple, and most of the antistatic tapes are PP/PE raw materials. Then blow the film. After the product enters, since the antistatic agent is distributed in the resin, and the antistatic agent is a low molecular weight external active agent, it has the characteristic of hydrophilic moisture absorption, and easily migrates from the inside of the resin to the surface of the product to be hydrophilic (absorbing air moisture) to form a The layer of water molecules thus achieves the effect of static electricity discharge.
It also shields ESD electrostatic discharge and external electromagnetic radiation from external personnel and equipment. Anti-static tape is suitable for transportation and packaging of electrostatic sensitive high-tech electronic products such as PCB and IC. Not only have anti-static tape all anti-static properties. It has excellent anti-static, anti-radio frequency, waterproof vapor penetration, anti-salt spray and many other functions. The unique four-layer structure creates a "sensor cover" effect to prevent the contents of the electrostatic tape from being isolated from the electrostatic field. In addition, the inner layer is composed of static ethylene, which has excellent anti-static function. The inner and outer layers of the anti-static shielding material are made of transparent anti-static materials, and the middle is a translucent conductive metal layer. Therefore, it has good anti-static and electrostatic shielding properties. The appearance is silver-gray and translucent, and the packaged objects can be seen through.
