The product range can meet almost all requirements of applications and performance in the market.
First-class equipment and production technology can ensure a stable and lasting good performance of the high-precision stick.
SUN HONG coating blade has been used in different paper and paper machine,proved that ours coating blade can improve equipment performance and paper quality, thereby improving productivity.
The following table shows the different types of blade wear and the corresponding treatment methods. This inspection method is very effective.
| Problem | Reason | Measure |
| Uneven wear, frequent blade replacement | 1. The surface of 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 middle or edge of 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 gasket at the back of blade if necessary 2. Replace the old and sunken blade |
| Excessive wear at one end of blade | The displacement of blade is not parallel to the axial direction of roller or dryer | Add gasket, if necessary, move bearing and bracket to adjust scraper parallel to axial direction |
| The blade is worn evenly, but the end face is rough | 1. There is deposit on the surface of roller or dryer 2. The pressure of blade is too high 3. The material of blade is too hard |
1. Use abrasive blade when necessary 2. Reduce the pressure 3. Use a slightly soft blade |
| Excessive wear in sheet area | The sheet leaves sediment on the roller or dryer | 1. Use abrasive blade when necessary 2. Trim the edge of blade frequently 3. Use blade with slotted end to prevent excessive pressure on both ends of roller or dryer |
| Excessive wear out of sheet area | The sheet lubricates the roller or dryer | Use blade with 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 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 |
