How to judge whether the anti-static rubber needs to be replaced?
To judge whether the anti-static rubber needs to be replaced, there are several ways to do it:
1. Appearance inspection:
- Observe whether there is severe wear, cracks, scratches or deformation on the surface of the rubber.
- Check whether there are stains or mildew that are difficult to clean.
2. Performance test:
- Use an anti-static tester to regularly test the anti-static performance of the rubber. If the resistance value exceeds the specified range, it means that the anti-static effect has decreased.
- Check whether the conductivity of the rubber is uniform and whether there is any local loss of conductivity.
3. Service life:
- Judge according to the service life of the rubber and the manufacturer's recommended replacement cycle. In general, the service life of the anti-static rubber is 3-5 years, but it depends on the environment and frequency of use.
4. Environmental factors:
- If the rubber is in an extreme environment (such as high temperature, high humidity or strong ultraviolet radiation) for a long time, it may need to be replaced more frequently.
5. Maintenance records:
- Refer to the maintenance records to understand the historical maintenance of the rubber and performance change trends.
