Based on the 1760/600 12-roller super calender which has been put into production successfully, it was designed and developed by the Light Industry Hangzhou Institute of Mechatronics Design (China National Light Industry Association Hangzhou Machinery Design Institute) based on user requirements. Leshan City, Chengfa Papermaking Machinery Co., Ltd. (Leshan Papermaking Machinery Factory) manufacturing, Light Industry Hangzhou Electromechanical Design and Research Institute supporting electric drive components, new 760/350 12-roll supercalender with heating and cooling system heat rollers, was in 2001 5 The company started production at Ningbo San A Group Co., Ltd. as an accessory for the production of coated coated paper after 760/350 double sided blade coater (another overpressure machine is being installed).
The machine is equipped with 105 g/m2 coated coated paper (with a basis weight of 70 g/m2 and coated with 17 to 20 g/m2 per side) in case the hot roll is not hot water, and the speed is 200m/min at the overpressure machine. When the line pressure is 200kN/m, the physical indicators of the finished coated paper are: smoothness 770-860s, glossiness 55.6%-56.5%, whiteness 86.67%; four chills in the middle When the hard roller passes through hot water of 50-60°C, 128g/m2 double sided coated paper is finished, the speed is 300m/min (maximum 350m/min), the smoothness is 1000s when the line pressure is 200kN/m, glossiness About 60%. Finishing 80g/m2 single-sided coated paper, the speed is 250m/min, the smoothness when the line pressure is 200kN/m is 400s, the glossiness is about 60%, and reaches the quality index of coated paper.
