How to verify whether the anti-static workbench meets the standard
With the increasing number of anti-static workbench R&D manufacturers, there are still many informal small factories among them. Due to the special requirements of anti-static workbenches, it is recommended that you can choose the workbench first. The anti-static function is tested, so that problems can be avoided in use. Not only that, the anti-static function must be checked regularly, and a series of problems caused by static electricity can be relatively reduced. Then, how to verify whether the anti-static workbench meets the standard?
1. How to verify whether the anti-static workbench meets the standard?
1. Detection of surface impedance
The detection surface requires that four points be taken on the four corners of the table, and the electrostatic detector is placed in the designated position. Usually we only record one of the four points, but the maximum value within the value must prevail.
2. Detection of ground impedance
Ground detection still needs to take four points at the four corners of the table, and place one pole of the detector on the detection position and the other pole on the ground, and then perform detection and record. We only need to record one point on the ground impedance. The maximum value of the value is recorded.
3. The frequency problem detected by the anti-static workbench
It should be noted that the detection frequency of the anti-static workbench should be controlled. Some people may think that more testing is better, but the anti-static workbench R&D manufacturer does not recommend that you perform too frequent testing. Generally speaking, half A monthly inspection is also possible, and the inspection time can be shortened as appropriate to ensure normal operation.
2. Scope of qualified anti-static workbench test
Generally speaking, what we need to do is to check the resistance value of the anti-static workbench, that is to say, just check the surface resistance and system resistance, if its value can be within the qualified range of 106-109Ω, Then if it is in this position after the test, it indicates that the resistance value of the anti-static workbench, that is, the surface resistance and the system resistance, the qualified range is 106-109Ω.
Generally, new workbenches are best tested according to the above methods. Not every anti-static workbench R&D manufacturer is fully qualified, but for the chemical industry, every anti-static workbench is very useful.
