What is the difference between esd chair and ordinary chair?
Anti-static chair is a must for many enterprises. It uses ESD seat cushion, backrest and metal fittings to effectively discharge static electricity to the ground. It has very good ESD static discharge performance and can meet the clean room cleaning. standard. However, many people have certain misunderstandings about anti-static chairs. Many people think that only the anti-static chair's drag chain can play an anti-static role. If there is no grounded chain, the anti-static chair will be like an ordinary chair, and it will not play any role. In fact, it is not true. The good anti-static chair of Yatong is not only the grounding chain can play the role of static discharge. Its five foot cups or casters are enough to achieve the effect of discharging static electricity. The foot cup or caster is made of conductive. Made of nylon material, grounded at five points, discharge static electricity, can achieve the same effect as the drag chain, and more convenient and beautiful.
The backrest and the seat cushion adopt the modified polyurethane closed-cell foaming technology, and the anti-static PU material is integrally foamed. It contains δ= 2mm stamping and forming high quality steel plate inserts.
Surface resistivity: 10-10Ω Ground resistance: <10Ω
The working principle of singing anti-static chair: ESD chair is an essential item in the operation of static sensitive area. Anti-static chair uses ESD seat cushion, backrest and metal fittings to effectively prevent static electricity. To the ground, has very good ESD static discharge performance. The surface of the dust-free chair is free of oxides, and the chair material is subjected to strict dust and ionic contamination tests in the laboratory to ensure that the dust-free studio standard is met.
Ordinary chairs without armrests will feel unbalanced and uncomfortable, and there is no place for the hands to be placed. It has made sense that the chairs have been handrails for so many years.
However, the larger the contact surface of our anti-static chair, the easier it is to generate static electricity; from the cost point of view, the armchair is more expensive than the chair, and there is very little such demand. Therefore, the general workshop production needs anti-static chairs without armrests.
