Self-Lubricating Property of Paper Machine Doctor Blade

Carbon fiber composite doctor blades have excellent self-lubricating properties with a low friction coefficient, typically between 0.15 and 0.25, much lower than metal blades. During high-speed operation, they effectively reduce friction resistance against the cylinder surface, avoiding dry abrasion and overheating. This protects the dryer cylinder and significantly reduces motor load and energy consumption. The material contains inherent lubricating components, enabling stable operation without additional lubrication. It runs smoothly with low noise, resists wear and sticking, improving stability and saving energy for high-speed paper machines.
