The methods of improving the evenness of the paper machine are generally as follows:1. Reduce the proportion of long fibers:The ratio of pulp is changed from the original 20%: 80% to 10%: 90%, so that the ratio of medium and long fibers to short fibers is reduced from the original 20%: 80%.The longe

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

The parts of the daily inspection of the paper machine are as follows:1. Whether the connection lines are in poor contact, especially the associated signal lines, such as feedback lines, communication lines, input and output lines between load distribution points, etc.;2. Check the PLC program, whet

As one of the indispensable equipments for paper processing at present, the paper cutter is easy to use and must pay attention to the use of safety and literature. Many operators tend to ignore safety when operating paper cutter equipment, resulting in unnecessary losses. So what are the factors tha

Maintenance measures of papermaking equipment should consider theseThe operational performance and reliability of papermaking equipment are greatly tested because they usually work in harsh process environments such as heavy load, strong corrosion, and high temperature.On the one hand, strengthening

Before cooking or refining, the papermaking raw materials are pretreated and processed according to the requirements of the cooking or refining process. They are divided into non-wood fiber preparation equipment and wood fiber preparation equipment. The former includes grass cutters, reed cutters, a
