A process for improving the life of papermaking belts containing a cured photosensitive polymeric resin is disclosed. The process includes the continuous application of an effective amount of chemical compounds capable of slowing down the degradation rate of the photosensitive polymeric resin to the belt's surface during the papermaking operation. Preferably, the chemical compounds are antioxidants which inhibit or retard oxidation of the cured resin and its ensuing degradative effects.
Divulgation d'un procédé pour prolonger la durée de vie des courroies de machine à papier, contenant une résine polymère, photosensible, durcie. Ce procédé comprend l'application continue de quantités efficaces de produits chimiques, capables de ralentir la vitesse de dégradation de la résine polymère photosensible à la surface de la courroie, au cours de l'opération de fabrication du papier. De préférence, ces composés chimiques sont des antioxydants qui inhibent ou retardent l'oxydation de la résine durcie et les effets érosifs qui en résultent.
