Kadant UK has launched its nanotechnology enhanced composite doctor blade line.

The new line incorporates patented nanotechnology enhanced resins that allow for the composite resin matrix to be manipulated on a molecular scale to produce high-performing, wear-resistant doctor blades.

Michael Draper, research and development manager at Kadant UK, said: “The results from mill trials in Asia, Europe, and North America, as well as our own laboratory testing, have exceeded our expectations with respect to nano-blade performance and operating characteristics.

‚ÄúThe advances in matter manipulation, from microtechnology to nanotechnology, have allowed us to further enhance the performance of our doctor blades on the toughest applications, including stickies removal from lead-in paper dryers, hard-rubber wet end rolls, and critical positions on press rolls.‚ÄĚ

The nanotechnology-based doctor blades feature increased stiffness, increased resistance to chipping, improved inter-laminar bonding, and a lower coefficient of friction compared to conventional blades.

As a result, roll surface cleaning is improved and doctor blade life has been shown to increase significantly compared to that of conventional blades.

The company said the high-performance doctor blade results in fewer blade changes and the potential for reduced operating costs while enhancing overall doctoring and machine efficiency.

Kadant UK is a subsidiary of Kadant and based in Bury in the UK.

It is a provider of doctor blades, doctor blade holders, and doctoring systems for papermaking and other industrial processes.
