(FR) PRODUITS DE PLATRE ET LEUR PROCEDE DE PRODUCTION
Abstract: front page image
(EN)Plaster products comprising a mass of calcium sulfate dihydrate crystals intermingled with crystals of the double salt potassium sulfate-calcium sulfate hydrate and optionally the triple salt potassium sulfate-magnesium sulfate-calcium sulfate. Plaster products can be prepared from calcium sulfate dihydrate by adding to a water slum y of calcium sulfate dihydrate a potassium salt, especially potassium hydrogen-carbonate or potassium tetraborate but, in the first place, potassium sulfate, including a carrier, after which the water slurry is moulded and further worked in known manner to the desired plaster product, especially plaster board or moulds for the production of metal articles or ceramic articles.
(FR)Des produits de platre consistent en une masse de cristaux de sulfate de calcium dihydrate, melanges a des cristaux de sel double hydrate, de sulfate de potassium-sulfate de calcium et eventuellement de sel triple sulfate de potassium-sulfate de magnesium-sulfate de calcium. Des produits de platre peuvent etre prepares a partir de sulfate de calcium dihydrate en ajoutant a une boue aqueuse de sulfate de calcium dihydrate un sel de potassium, specialement d"hydrogenocarbonate de potassium ou de tetraborate de potassium mais, en premier lieu, de sulfate de potassium, et comprenant un materiau porteur, apres quoi la boue aqueuse est moulee puis travaillee de maniere connue jusqu"a d"un produit de platre desire, specialement des plaques ou moules de platre destines a la production d"articles metalliques ou d"articles de ceramiques.
