Working face: 1500mm-650mm Diameter: 300mm-1000mm Center distance: 1800mm-7000mm Adhesive thickness: 20mm-30mm Working speed: 300m/min-500m/min Roller material: HT300, surface cold hard cast iron |
The calender roll of the ordinary paper machine calender is a harder cold cast iron roll. For a sheet with an uneven surface, the roller surface will only touch the convex part of the surface, and not the low part. The tightness of the contact part is increased, and the strengthened pressure forms a light spot, which makes the surface characteristics uneven. Soft calendering technology uses the denaturation of the elastic roller to absorb unevenness of the paper surface, so that the paper surface is completely in contact with the iron roller surface. After calendering, the tightness of the paper changes smoothly and continuously, and the surface characteristics of the paper are invalid; The area is wide, the calendering time is long and the specific pressure is relatively reduced, which can reduce the thickness (small strength loss) and improve the smoothness.
