Product Description

Rollers in press section
The press section is the next part of the paper machine after the forming section. The most important functions of pressing are to increase sheet solid consistency in order to ensure adequate drying capacity, to consolidate the sheet, and enable web runnability in the early dryer sections. Increased sheet consistency increases wet strength and improves sheet consolidation and fiber-to-fiber bonding which increases sheet strength. This typically improves runnability and reduces press to dryer draw. Pressing can also have a significant impact on quality parameters such as smoothness, ink absorption, bulk, and moisture profile.

During pressing, the sheet is compressed between one or two fabrics and either two rolls, or a roll and a mated extended "shoe" in the press nip to squeeze water from inside the web and out of the felt fibers.
 

Rubber rollers
The rubber hardness of rubber rollers when producing general paper is usually 70 to 90 Shore hardness. The hardness of the rubber rollers used in each press of the press section increases with the increase of the pressure of each press line.

Sun Hong has never stopped the development of new press rolls. The purpose of developing new press rolls is to improve the dewatering efficiency, improve the quality of the paper sheet, and reduce the adverse effects of the press on the paper industry.
