Patent

CA 2229422

The invention relates to a method in a paper machine in connection with a moving element, such as cylinder, roll, felt, or wire, which is in contact with the paper web to be produced. The conditions are such that the moving element is exposed to substances in the paper web tending to adhere to the moving element and to impair its operation in the process of paper production. A composition is applied to the moving element, such as the central roll (1) in the press section, e.g. by a nozzle structure (4). This composition, such as flushing water, to which a possible releasing chemical has been added, comprises at least one enzyme selected in a way that it acts by a chemical process on at least one substance adhering from the paper web (6) to the moving element, such as the center roll (1). The purpose of the chemical process is to release and/or decompose said at least one adhering substance from the moving element, i.e. the center roll (1), to maintain and/or improve its reliability in the process of paper production.

L'invention a trait à un procédé utilisé dans une machine à papier, en liaison avec un élément mobile, cylindre, rouleau, feutre ou toile machine, en contact avec la bande continue de papier à fabriquer. Les conditions de fabrication sont telles que l'élément mobile est exposé à des substances se trouvant dans la bande de papier ayant tendance à y adhérer et à entraver son fonctionnement dans le processus de fabrication du papier. On applique une composition sur cet élément mobile, le rouleau central (1) par exemple, de la partie constituant la presse de la machine à papier, à l'aide d'une buse (4). Cette composition, de l'eau d'entraînement à laquelle on a ajouté une substance chimique possible de refoulement, contient au moins une enzyme choisie de façon à ce qu'elle agisse par un processus chimique sur au moins une substance adhérant depuis la bande continue de papier (6) en direction de l'élément mobile, le rouleau central (1) notamment. Le but du processus chimique est de libérer cette substance adhésive de l'élément mobile, le rouleau central (1) en l'occurrence, ou de la décomposer et ce, afin de conserver au procédé de fabrication du papier sa fiabilité ou de l'améliorer.
