Causes
- High mechanical load
- Abrasion by fibers and media
- Coating unsuitable for load
Effects
- Reduction of surface roughness
- Slippage
- Disturbances in the application pattern
- High change intervals
The mechanical stress caused by starch or pulp, for example, leads to a reduction in surface roughness due to abrasion or smoothing and thus to a change in the coating. This ultimately leads to a shorter service life of coating, sizer or backing rolls.
