How to solve paper machine rewinding cracks:1. The uneven hardness or moisture content of paper rolls in papermaking machinery should be improved.2. Whether the setting of the stretching device is normal.3. Remove pulp lumps on the dryer cylinder, draw roll or spreader roll.4. Before installing the

In the auxiliary system of the paper machine, the energy consumption of the vacuum system accounts for 30% to 40% of the whole system, and some are even higher.Problems faced by vacuum systemIn the auxiliary system of the paper machine, the vacuum system occupies an extremely important position in t

The spiral surface coating is repaired using the multi-layer wood plasma surfacing technology, which uses a plasma power source to form a high-temperature arc column on the damaged surface, melting the composite coating of tungsten carbide alloy powder, thereby repairing and restoring scars on the m

Every link in all walks of life is inseparable from paper, and it is inseparable from the papermaking industry and papermaking machinery. The papermaking machinery will be subject to different degrees of wear and tear in every link when it is working. In this issue,。From a log cutting tool, the blad

The multi-layer slanted mesh former distributes pulp in multiple central pulpers and sizing in layers in the headbox. It adopts unique rectification and layering technology to realize the layered forming of fibers in the forming area, which can achieve two-layer, Three or more coats of sizing. In the production of slanted nets, the on-site control of the quality of papermaking and the process parameters of normal operation should be carried out.

Generally, it can be divided into main body and auxiliary system, and the main part is divided into wet part, stem part and curl part. The wet end can be understood as the part of the paper with a high water content; the dry part is the dry part with very little water; and the curl is the mechanism
