Product Desciption
Things you need to know about felt lint ? Why and How to slove it ?
Reason:
There are many reasons for the damage and the lint of the felt, mainly two of which are scraped by machine parts and chemical damage.
1.The most common reason is that the surface of the press felt torn loosened by high pressure water.
2.Lack of lubricating water between the vacuum panel and the blanket, which causes the temperature rise and the fiber is damaged.
3.Material of Vacuum suction cover is bad,large in friction coefficient, the edges of the cover and the seam has burrs or with sharp blade shaped, without rounding out the edges,the wrap Angle between the vacuum box and blanket is too large, high vacuum degree, local surface irregularities,fixed screw exposed,the above will lead to blanket abrasion .
4.Supporting roller surface with burrs, iron molds , the roller surface wrapped with slurry, or expander roller rubber thread stand is too high or stand has obvious edges and corners,no sharp edges exists between eight openings and rubber roller body or the high and low transition zone is too short, etc are likely to cause blanket abrasion .

Solution:
1.For paper machine especially middle speed or high speed paper machine,the rational use of lubricating water now only benefit to the clean degree of the blanket but also produce a water film between the vacuum panel and blanket which play a role as a lubrication, sealing and cooling effect.
2.Vacuum panel slit between the two strips should be used the same material as the panel material or lower wear-resisting performance than the panel material. From the outside of the vacuum area from dense to sparse and with appropriate amount of lubricating water.
3.All supporting roller surfaces should be smooth without burrs and rust,and copper rollers, stainless steel rollers and rubber rollers are options.
4.There is a speed difference between the relevant transmission points, causing the blankets to rub and wear out.Adjust the speed ratio of each transmission point correctly to avoid the abnormal speed difference.

SUN HONG PRESS FELT
The press felt plays an important role in removing the water from the paper web after the forming section, and at the same time imparting smoothness and conveying it to the dryer section. For this reason, the press felt needs to provide the following functions: Water removal, smoothness and runnability. In recent years, larger and faster paper machines require press felts of even higher consistency and quality.
At SUN HONG, we seek uniformity on every aspect of the production process. Using digital controls, we are able to manage the entire process with great precision, and to implement a high level of quality control on all aspects.
STRUCTURE
BOM Felt is composed of bottom net layer and fiber layer. The bottom mesh layer is made of monofilament, monofilament and multifilament composite chemical fiber materials. The single layer, double layer, multi-layer (1 + 1, 1 + 2, 2 + 2) and other organizational structures are made by using different weaving technologies; the common synthetic fibers in the fiber layer mainly include nylon staple fiber, polyester staple fiber and other fiber raw materials; the staple fibers with the same or different thickness are laid in layers on the bottom net, and then The bottom mesh layer and fiber layer are processed by needling, heat setting and other special post finishing processes to make BOM felt.
APPLICATION
Paper Making Felt refers to the fabric felt used in paper forming and conveying in paper industry. According to the position on the paper machine, it can be divided into wet felt, upper felt and dry felt.
Paper machine: cylinder,super forming,foudrinier,inclined wire machine,nip wire machine etc for forming section felt,press felt.
Machine Velocity:≤800m/min Paper:≥8g/m2 kinds of paper. NIP:≤80kn/m.
