PRESS ROLL FOR PAPER MACHINE, METHOD OF MANUFACTURING THE SAME, PRESSING METHOD FOR WET PAPER, AND SURFACE POLISHING METHOD FOR PAPER MACHINE PRESS ROLL

摘要

A paper machine press roll comprises a core roll and a ceramics sprayed film formed on an outer periphery of the core roll, in which values of Rk and Vo which are characteristic evaluation parameters of a plateau-structure surface of the ceramics sprayed film are Rk ‰¦ 8.0 ¼m
and Vo ‰§ 0.030 mm 3 / cm 2 .
(Vo = (100 - Mr2) × Rvk/2000 (mm 3 /cm 2 ) where Rk, Mr2 and Rvk are a core level difference, a core load length ratio and a projecting valley depth, respectively which are defined in JIS B0671-2-2002 (ISO13565-2-1996).
