Wire Part Paper Machine For Paper Mill
In the pressing section of the paper machine, several potential issues may arise, including crushing, edge folding, indentations, and paper perforations.
Light pressure is mainly applied to eliminate web marks and felt marks. At the same time, it also has the function of smoothing the paper surface and eliminating two-sided differences. If the pressure is too small, it will easily produce paper wool in the dryer. At the same time, it may not match the medium and high pressure, causing uneven pressure, resulting in PPS after coating. of unevenness.
The strength of the wet paper web is relatively low, and the speed difference requirements in the press part are stricter. The speed difference is larger at the connection between the wire part and the press part, because the peeling of the wet paper web from the wire requires a relatively large force, in order to prevent edge falling. Under the circumstances, it would be better to have a larger speed difference; however, it would be better to have a looser speed difference in the subsequent presses, because the paper sheet is in a suspended state here and does not rely on too much tension to exert pressure on the paper sheet. Disadvantage, of course, the paper cannot be too loose, and it must ensure normal peeling and ensure that there is no edge discount.
