Can Paper Machine Doctor Blades Completely Remove Stickies and Pulp Spots from Dryer Cylinders?

High-quality paper machine doctor blades can effectively remove stickies and pulp spots from dryer cylinder surfaces and minimize residue. The cleaning performance depends on the blade material, hardness, edge precision, and fitting uniformity with the cylinder surface. High-performance carbon fiber and composite blades feature good rigidity and moderate toughness, allowing close contact with the cylinder surface to continuously and stably scrape off deposits. Residue may occur locally if the blade is worn, pressure is uneven, or the installation angle is improper. By selecting wear-resistant and high-temperature-resistant blades and properly adjusting pressure and angle, combined with stable paper machine operation, residue can be greatly reduced, ensuring a clean dryer surface, improving paper surface quality, and reducing paper defects and breaks.
