| US$200.00-3,000.00 | 1 Piece (MOQ) |
| Problem | Reason | Measure |
| Uneven wear, frequent blade replacement | 1. The surface of the roller or dryer is uneven 2. The doctor holder is damaged or dirty 3. Sediment | 1. Use a softer blade 2. Clean, repair, or replace the doctor holder 3. Use abrasive blade |
| Excessive wear on the middle or edge of the blade | 1. The blade is not installed on the top of the roller 2. The old blade sinks (or leaves) the roller or dryer | 1. Refit or add a gasket at the back of the blade if necessary 2. Replace the old and sunken blade |
| Excessive wear at one end of the blade | The displacement of the blade is not parallel to the axial direction of the roller or dryer | Add gasket, if necessary, move bearing and bracket to adjust scraper parallel to the axial direction |
| The blade is worn evenly, but the end face is rough | 1. There is a deposit on the surface of the roller or dryer 2. The pressure of the blade is too high 3. The material of the blade is too hard | 1. Use an abrasive blade when necessary 2. Reduce the pressure 3. Use a slightly soft blade |
| Excessive wear in the sheet area | The sheet leaves sediment on the roller or dryer | 1. Use an abrasive blade when necessary 2. Trim the edge of the blade frequently 3. Use a blade with a slotted end to prevent excessive pressure on both ends of the roller or dryer |
| Excessive wear out of sheet area | The sheet lubricates the roller or dryer | Use a blade with a slotted end |
| Local depression | The blade is damaged, electrostatic (discharge/ electrolysis /heating) | Insulate the blade from the holder or use a non-metallic blade |
| The blade produces a burr | 1. The material of the blade is too soft 2. The pressure is too high 3. The angle of the blade is too small | 1. Use a slightly hard scraper 2. Reduce the pressure 3. Adjust the bearing or bracket to increase the angle, and use the instrument to check and correct the angle |
