Description

Herstellung künstlicher Steinmassen aus Gips. Das in der Patentschrift 39112,5 beschriehene Verfahren zur Herstellung künstlicher Steinmassen aus Gips und Magnesiumsulfit zeigt erhebliche Mängel, weil die Beschaffung von Magnesiumsulfit aus Magnesiumoxyd oder Magnesiumkarbonat in großen Mengen zu kostspielig ist, daher technisch nicht verwertbar ist.Manufacture of artificial stone masses from plaster of paris. The process for the production of artificial stone masses from gypsum and magnesium sulphite, described in patent specification 39112.5, shows considerable deficiencies because the procurement of magnesium sulphite from magnesium oxide or magnesium carbonate in large quantities is too expensive and therefore cannot be used technically.

Es wurde nun gefunden, daß die Herstellung künstlicher Steinmassen von noch größerer Härte viel billiger gestaltet werden kann, wenn man an Stelle des aus dem teuren Magnesiumkarbonat hergestelltenMagnesiumsulfits sich eines Magnesiumkalziumdoppelsulfits bedient, das aus natürlichem Dolomit und schwefliger Säure in unbeschränkten Mengen billig gewonnen werden kann.It has now been found that the production of artificial stone masses of even greater hardness can be made much cheaper if one in place the magnesium sulfite made from the expensive magnesium carbonate is a magnesium calcium double sulfite that is made from natural dolomite and sulphurous acid in unlimited quantities can be obtained cheaply.

Es ließ sich nicht voraussehen, daß Dolomit ebenso wie Magnesiumkarbonat allein dazu geeignet ist, und noch viel weniger war zu vermuten, daß die Verwendung des Magrnesiuinkalziumdoppelsulfits den Härtegrad solcher Steinmassen noch um ein beträchtliches erhöht.It could not be foreseen that dolomite, like magnesium carbonate, would alone is suitable, and even less was to suspect that the use of Magrnesiuinkalziumdoppelelsulfit the hardness of such stone masses by one increased considerably.

Beispiel. ro Teile gemahlener Dolomit werden in geeigneter Weise mit schwefliger Säure behandelt und mit zoo Teilen gebranntem Gips unter Wasserzusatz zur plastischen Masse verarbeitet, die rasch erhärtet.Example. Ro parts of ground dolomite are appropriately mixed with Treated with sulphurous acid and with zoo parts of plaster of paris with the addition of water processed into a plastic mass that hardens quickly.
