Abstract

L'invention concerne l'industrie de la fabrication d'articles en plâtre. On obtient les produits en plâtre en ajoutant à une bouillie aqueuse de sulfate de potassium dihydrate un sel de potassium, de préférence le sulfate de potassium, avec une substance porteuse, puis en moulant et traitant le produit obtenu de façon usuelle. Application à la fabrication de carreaux et moules en plâtre.The invention relates to the plaster articles manufacturing industry. The plaster products are obtained by adding a potassium salt, preferably potassium sulfate, with a carrier substance to an aqueous slurry of potassium sulfate dihydrate, followed by molding and processing the product obtained in the usual way. Application to the manufacture of plaster tiles and molds.
