The doctor blade contacts the paper surface with its straight edge and uses a certain amount of pressure to scrape off excess liquid material from the paper surface. The principle is similar to the operation of scraping off ink or paint, but in the paper industry, the requirements for doctor blades are more stringent and require higher precision and stability. In the paper making process, doctor blades are widely used in many aspects, including coating, coating and surface treatment.

Advantages of Doctor Blade

1. Ensure uniform coating and improve the smoothness and surface quality of the paper.
2. Using doctor blades reduces scrap and increases production efficiency because they allow precise control of coating thickness.
3. Material waste and production dead time can be reduced, thereby reducing production costs.
