Sun Hong Doctor Blade Series
The Function of Doctor Blade
Paper machine doctor blade is used to remove contaminant, water, broken paper, and pulp fibers from the surface of the roller to prevent these substances from accumulating and damaging the fabric and felts or affecting the quality of the paper.
Doctor Blade Apply for Different Use Position
Apply for forming section:They are used for breast roller, couch roller, wire drive guide roller to ensure the cleanliness of the white water system and prevent fiber blockage.
Appliy for Press Section :They are used for top press roll and felt guide roll, removing broken paper, and protecting the press felt.
Apply for Dryer Section: They are install at the psotion of dryer cylinder, keep dryer cleaning and increase heat transfer efficiency.
Material of Doctor Blade
The doctor blade have many different material, metal material such as steel, bronze, stainless steel and composition material such as HDPE, glass fiber, expoy resin, carbon fiber material.
HDPE Material
HDPE doctor blade is made of high density polyethylene, with good wear resistance and long service life, suitable for paper making, printing and other industries. Sun Hong's HDPE doctor blade can operate for a long time in high temperature, high humidity, acid and alkali environment, and is suitable for soft rubber rollers, polyurethane rollers, etc. in the wet part of paper machines. High molecular polyethylene improves the lubricity of doctor blades and can withstand high temperatures of 80°C. The molecular content is 3-6 million.
(1) Good wear resistance: Made of high density polyethylene, suitable for high speed operation of paper machines, reducing replacement frequency.
(2) Corrosion resistance: HDPE doctor blade can still maintain stable performance in strong acid and alkali environments and is not affected by chemicals in pulp.
(3) Low friction coefficient: HDPE doctor blade contacts the roller more smoothly, reducing equipment surface wear and improving paper quality.
HDPE-1 Application: Breast rollers, soft rubber roll, polyurethane rollers, etc. Specialty: 80°C temperature resistance, molecular weight 3 million |  |
HDPE-2 Application: Wet section, soft rubber coated roll, Specialty: 80°C temperature resistance, molecular weight 6 million |  |
HDPE-3 Application: Wet section, soft rubber coated roll, Specialty: 80°C temperature resistance, molecular weight 8 million |  |
