Super calender is a kind of calendering equipment in papermaking. Shape similar to mechanical calender, but the number of rollers more. Applicable to coated paper, coated paper, writing paper, offset printing paper and other cultural paper and capacitor paper and other insulating paper.
Equipment structure
The equipment consists of a metal roller and a paper roll arranged vertically. Roll number of 5 to 12 roll, individual paper up to 15 to 20 rollers. The paper roll is made of high-pressure, such as sulphate wood pulp, cotton, wool, hemp and asbestos. Operation, due to the number of rollers, the line pressure, paper roll deformation of the paper to produce friction to further improve the paper gloss, smoothness and tightness. Super calender speed faster, more than one use. Generally also equipped with a retractable paper tray, reel and special lift platform and other ancillary devices. Used for finishing paper such as writing paper, offset printing paper, coated paper and capacitor paper.
The main function
In addition to cold cast iron roll, about half of the paper roll, wool, rags or asbestos as raw material made of paper roll paper, strong and strong, and flexible. Normally the bottom roller is the driving roller, and the other rollers are rotated by the friction between the rollers. The sheet is rolled to significantly enhance the gloss and smoothness of the paper and improve the appearance. In the machine on the basis of pressure to further improve the paper smoothness and gloss, while increasing the tightness and improve the thickness of the uniformity of the process for the super-Calender machine.
