In the production process management of modern paper machine, doctor blade is a very important part. It can effectively improve the operation performance of the whole production line, ensure the cleanness of roll surface, make the web stripping easier to control, and reduce broken ends and holes.
Classification of doctor blade
Phosphor bronze blade
High quality copper alloy is suitable for drying cylinder, Yankee drying cylinder, paper roll calendering roll, etc. It is flexible in the metal blade, low friction coefficient, good dirt cleaning effect and not easy to damage the cylinder roll.
Polymer blade
Synthesis of molecular polyethylene and abrasive materials. Operating temperature ≤ 80 ºC. It has low friction coefficient and is suitable for soft rubber rollers
Cotton fiber blade
Synthesis of three-dimensional reinforced cotton fabric and phenolic resin adhesive. Operating temperature ≤ 150 ºC. The blade with small friction coefficient, which has strength and toughness, is suitable for hard rubber roller, copper plating, chromium plating roller, etc.
C20 carbon fiber scraper blade
29% carbon fiber, 71% high-strength glass fiber, high-temperature resin adhesive and high-performance wear-resistant material. Operating temperature ≤ 200 ºC. It is suitable for hard cots in drying department, pressing department and mesh department. It can effectively solve the roll surface with rough surface and difficult to clean. It is widely used and has a large amount of use
Glass fiber doctor blade
Glass fiber, high temperature reinforced resin adhesive, synthesized by adding special lubricating and wear-resistant materials. Operating temperature ≤ 180 ºC. High temperature resistance, good wear resistance, enhanced cleaning effect, suitable for parts with high cleanliness requirements.
Toilet paper machine doctor blade
The wrinkling scraper is made of carbon steel, with strong toughness, good wear resistance, long service life and high mechanical properties, which can improve the production process and efficiency. The new wrinkle scraper is a carbon steel blade sprayed with high-density coating, which significantly improves the quality, service life and mechanical efficiency.
1.Peel sheet :The doctor blade is installed at the correct position on the surface of the roller or dryer from which the paper is peeled, so as to effectively assist the production workers to bring the paper from the wet part to the dry part to the coiler.
2.Roller surface cleaning :The doctor blade design should help to clean the water or dirt on the surface of the roller or dryer, keep the roller surface or cylinder surface clean, and improve the product quality and paper machine efficiency.
We can make your paper-making equipment more efficient, paper more stable. Reasons to choose the material:
1.According to different use parts or different rolls materials, you can choose different material of doctor blades, with lower friction coefficient.
2.Long life: Choose high-quality EP synthetic resin material, carbon fiber, polymer materials and advanced production technology worldwide, 50% longer than other domestic material.
3.Low thermal expansion coefficient, long time sintering laminated, excellent uniformity and the internal stree-relieved.
4.Excellent gliding property can greatly protect equipments operating.
