Whether the steam supply system in the drying section of the paper machine is very reasonable will have a great impact on the quality of the final paper produced in the drying section, the consumption of steam, and the operation management. 1. Principle designWhen we are making paper, we must

The raw materials of my country's paper industry include plant fibers, mineral fibers, and other fibers. Plant fibers are divided into wood, bamboo, grass, etc.; mineral fibers are divided into asbestos, glass fiber, etc.;The fibers also include polymer materials obtained from petroleum cracking. At

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

my country's paper industry has developed very rapidly in recent years. Similarly, the application of frequency converters in the transmission system of paper machines is becoming more and more common. This article introduces several commonly used frequency converter parameters and setting methods i

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
