Coated White Paper Board Making Process
In the coated white paper board making process, increasing coating amount can reduce coast and increase profits, so for high quality white paper board making, how to control the coating amount in coating white paper board making process?
Coated White Paper Board Making Control
1. Reduce the doctor blade pressure to increase coating amount: After the doctor blade pressure is reduced, the reaction force to the action of the coating liquid will be reduced accordingly, so the dominant liquid action in the wedge region will increase the coating amount of coated white paper board.
2. Increasing the angle of the doctor blade beam to increase the coating amount: After the angle of doctor blade beam is increased, the space in the wedge-shaped area under the knife edge will be correspondingly increased, the liquid action of the coating will be enhanced, and the coated white paper board coating amount will be increased under the same scraper pressure.
3. Reducing the thickness of doctor blade: When the thickness of doctor blade is reduced, the reaction force of the blade to the action of the coating liquid is reduced, and the liquid action that is dominant in the wedge-shaped region will increase the coated white paper board coating amount.
