"Calendar" refers to equipment that is used in paper machines and their accessories and can improve surface performance. It includes the various types described here. Paper machine calenders, semi-dry calenders, smooth Terms such as calender, super friction calender, hot-dip calender, and embossing calender refer to the method used or the function completed. Except for the machines described later (referring to embossing and calendering), All other functions can improve surface smoothness and gloss performance.
(1) Paper calendering is a mechanical process that compresses the paper web and improves surface properties. Therefore, calendering reflects the quality standards of the papermaking and coating process.
(2) Calendering includes three elements: pressure, relative deformation and temperature of paper and pulp rolls.
(3) The efficiency of calendering is the approximate balance between the responsiveness of the coated paper and the total amount of calendering provided. The responsiveness of coated paper is determined in advance by the characteristics of the paper and its coating.
(4) There is a limit to the total amount of paper and/or coating performance that can withstand calendering. Beyond the limit, the calendering effect usually degrades the quality of the paper and correspondingly loses printability.
(5) The performance of coated paper is the sum of the internal performance of the paper itself and the external performance of the coating (according to the recent point of view, the internal performance of the coating is also very important).
(6) Among the many variables encountered in the production of calendered paper, only 5 variables have an impact on the control of calendering: pressure, moisture, speed, temperature and roller structure.
