To realize the discharge of static electricity must constitute a circuit with the ground (i.e., to ground), ordinary plexiglass/PVC/PC board is an engineering plastic, is an insulating material (surface resistance and volume resistance are in the 10th of the 15th to 16th or so), charge can not be free to flow on top of it, if in some parts of the due to friction or other reasons for accumulation of charge (static), even if the material is grounded, but also can not drain the static electricity. Static electricity, because the charge in the above can not flow freely; anti-static plexiglass / PVC / PC board due to the surface is a layer of anti-static layer, the surface resistance of 10 6 to 8 times the square ohm, the charge in the above can flow freely, when some parts due to friction or other reasons for the accumulation of charge (static), and anti-static plate and the ground constitutes a circuit (i.e., grounding),
The static electricity generated at this time The static electricity generated can be discharged along the antistatic layer in a very short time (0.1 seconds), thus not causing harm to sensitive components and preventing the accumulation of dust adsorption.
