How to choose high-performance anti-static chair
The high-performance anti-static chair is a must-have item for homework in static-sensitive areas. It is commonly used in clean rooms, microelectronics manufacturing, communications, aerospace, ships, new resources, automotive electronics, medicine, petrochemicals, defense military industry, industrial Internet, things Networking, new raw materials and other industries. In addition to the performance of ordinary chairs, anti-static chairs also have long-term anti-static performance. It is usually composed of three parts: antistatic packaging fabric, antistatic chair maintenance part, and antistatic chair caster. The basic plastic material is made of static conductive nylon. After manufacturing anti-static nylon wheels, the static conductive wheels are connected to the anti-static floor or anti-static floor and supporting grounding system through a metal stainless steel maintenance frame.
The mechanism of the use time of the anti-static chair is that the anti-static chair wheel is connected to the ground through the static conductive shoes worn by the human body, that is, it is grounded to reach the goal of electrostatic discharge. Choose a high-performance anti-static chair should pay attention to the following two points:
1. A high-performance anti-static chair depends on whether its electrostatic conductivity index meets ESD industry guidelines. The so-called index is that the volume and surface resistivity of the chair are between >1×105Ω~<1×109Ω, and the resistance to ground is <1×109Ω. As long as a chair has long-lasting surface resistance and resistance to ground, it is useful for the caster to collide with the ground, and it will not delay the dust and fade, and it can achieve the best effect of electronic cleanliness and environment.
2. A high-performance anti-static chair also needs to control dust-free. Because the manufacturing workshops of many enterprises are thorough clean workshops, it is particularly important to prohibit dust pollution. Therefore, high-performance anti-static chairs should be dust-free and odor-free during use.
