Abstract

Procédé de fabrication de plaques de plâtre. On prépare une boue de plâtre en melangeant de l'eau et de l' alpha -semi-hydrate de sulfate de calcium dans un rapport compris entre 0,4 et 1,0 partie en poids d'eau pour 1 partie en poids d' alpha -semi-hydrate et, quand le rapport est compris entre 0,65 et 1,0, on incorpore en outre à la boue une argile capable de conférer des propriétés de thixotropie ou pseudo-plasticité à la boue, et on incorpore également à la boue une mousse usuelle.Manufacturing process of plasterboard. A plaster slurry is prepared by mixing water and calcium sulphate alpha-semi-hydrate in a ratio of 0.4 to 1.0 part by weight of water to 1 part by weight of. alpha -semi-hydrate and, when the ratio is between 0.65 and 1.0, a clay capable of imparting thixotropy or pseudo-plasticity properties to the mud is additionally incorporated into the mud, and it is also incorporated into mud a common foam.
