PURPOSE:To provide the doctor blade comprising a raw material capable of solving the defects of metal or resin-made doctor blades and used for scratching off paper refuses, etc., from a paper-producing roll. CONSTITUTION:The doctor blade is formed of a thermoplastic fiber composite material containing 30-80wt.% of polyphenylene sulfide and 20-70wt.% of either one of glass fibers, aramide fibers and graphite fibers. The doctor blade has good adhesivity to the surface of the roll of the paper-producing machine and can perform good scratching operations without injuring the surface of the roll. |
