Carbon Fiber Scraper Doctor Blades Strong And Stiff Whilst Simultaneously With Low Breaking Elongation

Carbon fiber scraper doctor blades used in the size press rolls of paper machine

Carbon fibres exhibit very good electrical and thermal conductance. The fibres are very strong and stiff whilst simultaneously having a low breaking elongation.

The doctor blades that we manufacture exclusively from carbon fibre fabric also have a very good cleaning effect. They were developed for areas with high levels of mechanical loading.

Our experienced service technicians can assist you with the selection of the right blades for your particular application.

Doctor blades is the main part of the paper machine scraper which used for cleaning the rolls’ surface.

Carbon fiber scraper is made of carbon fiber cloth or carbon fiber cloth plus glass fiber cloth or using carbon fiber cloth with glass fiber cloth plus silicon carbide layer fiber cloth or zirconium steel layer fiber cloth in the inner layer, and it is prepared by bonding with adhesive; Glass fiber cloth preg, cutting, spreading, heating and pressure curing to plate, and then slitting, cutting and grinding at the scraped end, the edge angle is 20-60 degrees; the scraped thickness is 1.5-10mm. The width is 76-270mm; the length can be customized as required.

The other end of the scraper is a connection end, which can be connected to the frame by U-shaped grooves or by copper rivets or by adding butterfly blades or by rivets or milling steps.

It has high temperature resistance, good strength, easy manufacturing, low cost, and easy to use.

Specification of Carbon fiber scraper doctor blades used in the size press rolls of paper machine

Scraper device

Components include: clamps, scraper blades, bearings, pressure and pressure relief devices, swinging devices.

Pressing part blade: a pressure roller blade to clean fine fibers and fillers, and a blade on the blanket guide roller to prevent dirt from contaminating the carpet, because the small fibers and fillers tend to transfer from the carpet to the smooth roller surface.

Drying blade: Press on the inlet and outlet of each group of dryers to remove paper breaks and dirt on the cylinder surface
