What should we rely on to purchase anti-static shoes?
The anti-static shoes can guide static electricity from the human body to the earth, thereby eliminating static electricity of the human body, and at the same time effectively suppressing the dust generated by the walking of the person in the clean room.
The anti-static technology of anti-static shoes mainly lies in the application of the technology such as sole and insole. At present, there are three kinds of sole forming technology, PU/PVC/PU molding at one time. The difference between PU and PVC is relatively easy. From the corner, the base fabric of PU is much thicker than PVC, and there are also differences in the feel. The PU feels softer and the PVC feels harder. So what should we purchase when purchasing anti-static shoes?
Those who often do electrical performance testing know that the material ratio of the anti-static shoe sole has very high requirements. If it is not good, first of all, the color, weight, hardness, etc. of the sole are not ideal, followed by the deviation of odor and performance. So we should pay great attention when choosing anti-static shoes.
In addition, when buying anti-static shoes, we must pay attention to the insole should be anti-static material, anti-static shoes themselves require resistance should be between 100K ohms to 100M ohms, so that is qualified.
Of course, after we buy qualified anti-static shoes, we should pay more attention to the usual wear. Anti-static shoes should be regularly tested for resistance during wear. If the resistance is not within the specified range, it will not be used as an anti-static shoe. It can only be worn as ordinary shoes or eliminated.
