  • modeling of Fourdrinier and cylinder Machines
    Developments in Chemical Engineering and Mineral Processing, 2008
    Co-Authors: Weidong Zhang, Xun Xu
    Abstract:

    In this paper, an “equivalent paper machine” is presented which possesses the features of both the Fourdrinier Machines and cylinder Machines, and a universal model is developed by mechanism analysis. The model is not only an external description as often obtained by system identification, but an internal one in which internal process variables are included. Experiments show that the model agrees closely with the plant data.

  • Treatment of sticky particles by surface application of talc
    2020
    Co-Authors: Peter Biza, Egon Gaksch, Manfred Hangl
    Abstract:

    Talc is very well known as a successful pitch and stickies control additive in paper industry. A possible concern of adding talc in the fibre suspension during stock preparation is the loss of talc in cleaning, screening, flotation and thickening. Despite the fact, that only the stickies on the sheet surface cause problems on the paper machine, the talc added to the fibre suspension also treats stickies which will be inside the sheet after sheet formation and will not cause any problems. The higher the specific sheet weight is, the higher is the number of stickies treated with talc but end up inside the paper. This is especially true for board and packaging materials of high basis weight. By treating only the stickies on the paper surface these disadvantages can be avoided. This is done by spraying a talc slurry onto the paper surface just after the head box. The correct amount of talc will be applied, the lower addition rates are more cost effective and the paper properties will not be influenced. By spraying talc on the surface of packaging paper and board after sheet formation several positive influences on the paper machine can be observed. A more constant PM runnability, less deposits on press rolls and drying cylinders, less dirt in felts and fabrics and finally easier cleaning and longer cleaning stop intervals can be achieved. Applying talc on the paper surface just after the head box is a cost effective way to improve production of board and packaging material. Due to the high specific sheet weight and the construction of the wire section this method is perfectly adapted to board and packaging grades produced on Fourdrinier Machines.
