The calender is matched with a paper machine with a corresponding clear paper width. It is mainly used to calender the copied paper to improve the smoothness, gloss and tightness of the web, make the thickness of the web uniform, and improve the appearance of the paper.
Zhang's appearance quality.
The working method of calender is usually continuous rolling. The printed matter is conveyed from the paper conveying table under the calender belt between the hot-pressing roller and the pressure roller. Under the action of temperature and pressure, the coating is attached to the surface of the calender belt and is calendered. After the calendering, the glazing layer is gradually cooled to form a bright surface layer. The calender belt is a specially treated stainless steel ring steel belt. There are multiple sets of far-infrared heating sources inside the hot-pressing roller to provide the heat required for calendering. Most of the pressure of the pressure roller adopts an electro-hydraulic pressure regulating system, which can accurately meet the requirements of the pressure in the calender. The calendering speed can be controlled by a speed-regulating drive motor or a slip motor.
