What is the reason for the broken ends of the paper in the dryer section of the papermaking machinery and equipment?

Everyone should know that the wet part of papermaking machinery is prone to breakage. Therefore, the water filtration capacity of the pulp and the dewatering capacity of the machine itself have become more concerned. Even if it enters the dry part, the paper will still be broken. It is possible that the head of the machine cannot be slackened. Next, the papermaking machinery manufacturer will come to Zhucheng Tiangong Papermaking Machinery Co., Ltd. to understand the reasons why the drying section may cause the broken ends of the paper.

The strength of the paper sheet itself is not enough or the paper sheet itself has weak points. For example, the moisture content of the paper sheet is too large, and when the knots of the dry cloth are irregular, it is easy to press knot marks on the paper, which will cause the paper sheet itself. Weakness that leads to page breakage.

The paper sheet is folded in the press section. In severe cases, the end of the paper is broken when the tension is relatively large in the later stage of drying, or there are transverse cracks and holes in the wet part of the paper sheet, which will also cause the dry part of the paper sheet to break.

When the basis weight of the paper sheet fluctuates, the drying speed is also inconsistent. The position where the basis weight of the paper sheet is small, the drying is faster, so it is easy to cause drying and so on, which will cause the paper sheet to shrink too much, and the end will break at the end of drying. When this happens, we need to address specific reasons.
