Description

Verfahren zur Herstellung von künstlichem Traß. Gemäß der Erfindung wird künstlicher Traß dadurch hergestellt, daß Waschberge mit uiedrigprozentigem Mergel gemischt, bis zur Sinterung gebrannt und gemahlen werden.Process for the production of artificial tassel. According to the invention Artificial tassel is produced by washing mountains with low percentage Marl mixed, burned and ground until sintered.

Der Mergel kann so, wie .er aus idem Bruch kommt oder fein zerkleinert, verwendet werden.The marl can be as it comes from the quarry or finely chopped, be used.

Es ist bekannt, daß oder wirksame Bes.tanidteil des Trasses aufgeschlossene Kieselsäure ist. Dieser Aufschluß der Kieselsäure ist auf vulkanische Tätigkeit, also auf starke Hitzeeinwirkung zurückzuführen. Dieselbe Wirkung wird erzielt, wenn man Kieselsäure stark erhitzt. Um aber reine Kieselsäure durch Wärme aufzuschließen, ist eine außerordentlich hohe Temperatur erforderlich. Fernerhin ist bekannt, aus Waschbergen und Kalksteinen durch Mischen in geeignetem Verhältnis; Aufbereiten, Sintern und Mahlen Zement herzustellen, wie aus der britischen Patentschrift 721z vom Jahre 1893 hervorgeht. Weiterhin ist bekannt, Silikate unter Glühen mit Kohle und Durchleiten schwefliger Säure aufzuschließen, wie aus der Patentschrift 24038 hervorgeht. Das neue Verfahren stellt ,nun nicht Zement her, sonldern einen Zuschlagsstoff. Fernerhin benutzt das neue Verfahren zum A.ufschluß der Kieselsäure Kalk, der im niedrigprozentigen Kalkmergel vorhanden ist, im Gegensatz zu dem bekannten Verfahren, wonach die für Zement so schädliche schweflige Säure zurr Aufschluß benutzt wird. Durch Idas neue Verfahren wird in einfachster Form ;in einem natürlich vorkommenden Rohstoff die Kieselsäure aufgeschlossen, ohne (daß (dieser Rohstoff vorher aufbereitet wird'. Auch ist es nicht erforderlich, vor oder nach dem Herstellungsprozeß irgendwelchen Zusatz zu machen. Die Gegenwart von Kalk, Eisen und Tonerde gestattet .den Aufschluß der Kieselsäure bei erheblich geringerer Temperatur als beim Fehlen dieser Stoffe erforderlich ist. Es ist somit gelungen, in denkbar einfachster Weise und unter Aufwand geringster Brennkosten und vor allen Dingen unter Benutzung von billigsten Rohstoffen einen einwandfreien, hochwertigen Mörtelzuschlagsstoff zu erhalten. Das neue Verfahren gewinnt dadurch noch an Bedeutung, @daß bisher wenig oder überhaupt nicht verwendete Rohstoffe zur Herstellung eines hochwertigen Baustoffes benutzt werden können.It is known that or effective Bes.tanidteils of the route open Is silica. This exposure of the silica is due to volcanic activity, therefore due to the strong heat. The same effect is achieved when silica is heated vigorously. But to break down pure silica through heat, an extremely high temperature is required. It is also known from Wash mountains and limestones by mixing in suitable proportions; Processing, Sintering and grinding to produce cement as described in British Patent 721z from the year 1893. It is also known to anneal silicates with charcoal and passing sulphurous acid through it, as described in patent specification 24038 emerges. The new process does not produce cement, but an aggregate. Furthermore, the new process for the digestion of the silicic acid uses lime, which is present in the low-percentage lime marl is present, in contrast to the known method, according to which the sulphurous acid, which is so harmful to cement, is used for digestion. Ida's new process is in the simplest form; in a naturally occurring one Raw material the silica is digested without (that (this raw material is previously processed will'. Nor is it necessary to do any before or after the manufacturing process To make addition. The presence of lime, iron and clay allows digestion the silica at a significantly lower temperature than in the absence of these substances is required. It has thus succeeded in the simplest possible way and under Effort of the lowest burning costs and, above all, using the cheapest Raw materials to obtain a flawless, high-quality mortar aggregate. That new procedures are gaining in importance because so far little or at all unused raw materials are used to produce a high-quality building material can be.
