This report describes wet-part-operating experience of PM 9 whose operation began at May, 1997.
We produce A 3 grade coated paper with this on-machine-coatar which is designed to attain the greatest productivity per capita possible and to bear the strongest worldwide competition. Now we are doing pretty good productionwise. As the key point is to keep good condition of wet-part operation, this report describes our operating experience of each section in the wet-part.
We summarize our experience for gaining good BD profile with the Module-Jet type headbox.Then we focus on the optimizing blade condition at forming box which is the core technique of the Duo-D former, and refer to the data on dewatering ability as well as operating conditions of Shce-Press installed in the third nip of wood-free base paper machine for the first time in Japan. We also emphasize the necessity for doctor-showering technique on ceramic roll to have longer blade life.
We are endeavoring to keep good operating condition in the wet-part and to have less defects, higher productivity and easily-controllable operating system under the motto “Easy Papermaking”.
