Burning paper machine surface quality

TIME:2019-05-27 BROWSE:2166

  The surface quality of the paper-making machine is customarily divided into the growth net, the round net, the net and the long round net according to the type of sheet former used; it is also divided into cultural paper machines according to its main product varieties. (including newsprint), board machine (including packaging paper), tissue machine, special paper machine; or thin paper machine, cardboard machine and conventional paper machine according to the thickness of paper production

  Use multiple processes to achieve good surface quality. Most of the paper is calendered by a mechanical calender after the paper machine to make the paper surface flat. The mechanical calender is made up of several cold cast iron rolls that flatten the paper surface with the weight of each roll or another pressurization. If higher surface smoothness is required, it should be calendered with a super calender. It is generally composed of a stack of paper rolls and cold cast iron rolls. Depending on the application requirements, some varieties are surface sized to improve surface quality; some are surface coated to improve appearance quality or print quality. Surface sizing and coating can be processed by paper machine outside the paper machine through a size press and a coater, or the size press and coating equipment can be combined in a paper machine for in-machine processing.
