Verfahren zur Steuerung der Oberflächeneigenschaften in einer Papiermaschine und Gebrauch
des Verfahrens zur Oberflächenbehandlung in einer Papiermaschine |
(57) The present invention relates to a method of controlling the surface properties of
surfaces in a paper machine by virtue of treating said surfaces with a surface treatment
compound to achieve desired surface properties. According to the invention, the surfaces
are treated with a liquid surface treatment compound whose characteristics are controlled
by modifying the backbone polymer chain of the surface treatment compound advantageously
by halogenated macrooligomers, diols, triols, thiols and/or other polyols. The invention
also concerns the use of the method in the surface treatment of surfaces in a paper
machine.
