Parameters of Antistatic Table Mat(Floor Mat) Specs Anti-static layer Surface resistanΩcm107-109 1.2mx10mx2mm Frition static voltage V<100 Conductivity layerSurface resistanΩcm≤106 Frition static voltage V≤106 Attenuation period of static voltage 5000-500V<50 <1.9s Volume resistance 107-109 Ω cm Laying method of Antistatic Table Mat Laying the anti-static mat on the table, then connect the grounding terminal with the surface and the other terminal with the ground. In this way, the accumulated static electricity on the table surface is discharged through the ground wire.The principles are as follows: The green layer absorbs and stores the static electricity on the table surface,resistance: 107--109Ωcm;The black base is a conductor with resistance less than 106Ωcm,which can discharge the absorbed static electricity;One terminal of the ground wire connects with the anti-static mat; the other connects with the ground. Therefore, the static electricity can be smoothly discharged to the ground. In this way, the static electricity on the table surface is discharged.
