Beijing PFM Screen Co., Ltd

As a   Paper Machine Clothing Manufacturer , share with you. Single Layer Forming Fabric 1. Too fast abrasion of the screen edge: The most serious wear of most paper machines are at the joints with and without vacuum (10-15cm of the screen edge); Solution: 1. Increase the opening of the vacuum box as much as possible. Staggered width. 2. Add normal pressure lubricating water to the edge of the vacuum box. 3. Add stiffeners in appropriate positions. 4. Check whether there are edges or gaps in the side wiper and the vacuum box. Especially the joints of the ceramic panels are weak links 5. Check whether the edges of each roll are severely worn (the diameter becomes smaller after wear, so that the tension of the mesh is smaller than the normal mesh surface and further accelerates the wear) 2. The overall wear is too fast: 1. The panel quality is not good enough. 2. The net tension is too small, the return tension of the single-layer net is 3-4kg/cm, and the return tension of the two-layer

  Double Layer Forming Fabric In the operation of the paper machine, the maintenance of the press felt without losing the surface properties of the paper sheet plays an important role that cannot be ignored. It is necessary to improve the press unit, strengthen the cleaning of felts, and choose new high-performance papermaking felts to ensure paper quality and extend the service life of the felts. Improvement of the device The use of detection devices: In the later stage of the felt use, the thickness of the felt decreases to a critical point. Because the felt is too thin, continued use will affect the dehydration efficiency and needs to be replaced in time. It is necessary to regularly check the history of the formation of the felt performance to predict the appropriate time for the felt to be taken off the machine. Improvement of process equipment: The single-shoe press section has only one nip and double-fleece on both sides. In this technology, the paper web passes through the thre

Papermaking felt is an important dewatering expensive consumable that must be configured in papermaking production. New replacement of the vacuum box panel, insufficient needle punching tightness of the blanket, too light shaping, excessive vacuum, no lubricating water between the blanket and the vacuum panel, improper selection of the vacuum panel material, excessive friction coefficient, and the use of the blanket in the later period will all cause the blanket.

  Dryer Fabrics Paper Machine Clothing Manufacturers  appreciate the ease of tailing, good running performance, long life and low fabric costs regardless of their machine or paper grade. Our high-quality woven fabrics come from our professional knowledge that can be traced back more than half a century, and the production of millions of square meters of fabrics. The largest product group in the dry fabric portfolio is double warp polyester (PET) fabrics-called Valmet Dry Fabric OR, OP and EOS after the product name update. Optimized materials for different operating conditions Factors that limit the running time of the dryer include hydrolysis, pollution, wear and damage. "Our PPS-reinforced dry fabric is very suitable for locations prone to hydrolysis. However, for dry fabric running time, pollution and mechanical wear are sometimes even more important than hydrolysis. In order to meet these challenges, MHR. It can withstand a sufficient degree of hydrolysis, But its seam strengt
