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
There are many factors affecting the forming of a paper machine, some of which are factors affecting dehydration, and some factors are "congenital" to the forming process, such as the characteristics of fibers in the pulp, the ratio of pulp, etc. Some factors are Due to the characteristics of the former, such as shaking, double-sided dehydration of the mesh, etc., some factors can be adjusted during the production process. The editor of Zibo Tianyang Paper Machinery Co., Ltd. will share the following
There will be short heads in the drying section of the paper machine. Even if the wet paper sheets entering the drying section have a dryness of more than 32%, they have a certain strength. Let's take a look at the main reasons for the breakage of the drying section of the paper machine with the edi
The headbox is a key part of a modern paper machine. Its function is to ensure that the paper material is evenly and stably connected to the Internet along the full width of the paper machine, and to ensure proper flow and flow rate, so as to form a uniform wet paper sheet on the Internet. creating condition. The structure and properties of the flow stock are decisive for sheet formation and paper quality.
The development status and future development trend of papermaking machinery in recent years have shown rapid growth, which has caused overcapacity to a certain extent, and the industry has encountered greater difficulties. Facts show that the extensive development mode has come to an end, and realizing the strategic transformation of the paper industry is an inevitable requirement for the industry to develop to the current stage. Therefore, adjusting the structure of the paper industry and realizing industry revitalization in the process of adjustment will be a necessary factor for the survival of enterprises in the harsh environment of the financial crisis.
The dryness of the wet paper out of the press section is generally only 30%~40%. In the new paper machine with compound press, the dryness is only 40%~50%. Therefore, it is necessary to use the drying cylinder to evaporate the water to make the paper dry. increased to 92%~95%.
