Abstract

Procédé pour la préparation d'une feuille de couverture en papier portant un appret de liaison, revêtue d'amidon et convenant à la fabrication de panneaux de parois en plâtre On prépare une composition de revêtement constituée d'eau, d'amidon cru non migrant et de sulfate de calcium en fines particules et on applique cette composition à la surface de l'apprêt de liaison selon un modèle dans lequel la composition de revêtement est appliquée dans des régions limitées, par exemple sous forme de bandes ou de rayures, laissant des régions appréciables de la surface non revêtues. Le procédé selon l'invention permet de parvenir à une excellente adhérence entre les papiers de couverture et les panneaux de plâtre intérieurs.A process for the preparation of a starch coated, starch coated paper cover sheet suitable for the manufacture of plaster wall panels A coating composition consisting of water, non-migrating raw starch is prepared. and calcium sulfate in fine particles and this composition is applied to the surface of the bonding primer according to a pattern in which the coating composition is applied in limited regions, for example in the form of bands or streaks, leaving traces. appreciable regions of the uncoated surface. The method according to the invention makes it possible to achieve excellent adhesion between the cover papers and the interior plaster panels.
