Description:
The calender roll of the plain calender is a harder chilled cast iron roll. For sheets with an uneven surface, the roller surface will only touch the raised parts of the surface, but not the lower parts. The tightness of the contact part increases, and the increased pressure forms light spots, making the surface characteristics uneven. Soft calendering technology uses the degeneration of the elastic roller to absorb the unevenness of the paper surface, so that the paper surface is completely in contact with the iron roller surface. The area is wide, the calendering time is long and the specific pressure is relatively reduced, which can make the thickness decrease less (intensity loss is small), and the smoothness is improved.
