Description

Modellschmiere. Gegenstand der Erfindung ist eine besondere Modellschmiere, die einerseits, der herrschenden Warenknappheit Rechnung trägt, anderseits aber auch wesentliche praktische Vorteile vor den bisher üblichen Modellschmieren aufweist. Sie ist anwendbar für jegliche Formen aus Gips oder anderen ähnlichen, auch zement- oder mab.-nesiazementhaltigen Kunststeinmassen.Model grease. The subject of the invention is a special model smear, which, on the one hand, takes account of the prevailing shortage of goods, but on the other hand also has significant practical advantages over the previously common model smear. It can be used for any shape made of plaster of paris or other similar, including cement or artificial stone compounds containing mab.

Als Schiniere war bei Formen, die zur Formgebung durch Gießen oder Pressen in erster Linie in Betracht kommen, Seifenlösung üblich. Infolge des Mangels an Seife wurden als Ersatz Gemische von Petroleum finit Paraffin oder mineralischen und vegetabilischen Ölen vorgeschlagen, wie sie beispielsweise auch als Stanz- bzw. Preßölmischungen bekannt waren. In solchen Fällen handelt es sich aber im wesentlichen nicht darum, die Ablösung der gestanzten Ware von den Stahlmatrizen, die hier leicht vonstatten geht, zu befördern, sondern der trockenen PreßmasEe einen besseren Zusammenhalt zu gewähren. Derartige Mischungen sind aber für Gipsformen, die vollkommen genaue Abdrücke oder Abgüsse ergeben sollen, nicht verwertbar. So gibt z. B. eine Schmiere aus Petroleum und. Paraffin Krusten und verursacht große Ungenauigkeit der geformten Gegenstände.As a hinge was used in forms that were used for shaping by casting or Presses primarily come into consideration, soapy water is common. As a result of the shortage In terms of soap, mixtures of petroleum finite paraffin or mineral were used as substitutes and vegetable oils proposed, for example as punching or Press oil mixtures were known. In such cases, however, it is essentially the case not about the detachment of the stamped goods from the steel matrices, which is easy here takes place, to convey, but the dry PreßmasEe a better cohesion to grant. Such mixtures are perfectly accurate for plaster molds Imprints or casts should result, not usable. So there are z. B. a goo from petroleum and. Paraffin crusts and causes great inaccuracy of the shaped Objects.

Die vorliegende Erfindung lehrt nun, als Formschmiere bei Gegenständen, die die Gestaltung der Form genau wiedergeben sollen, Gemenge von Petroleum und Wachs (Bienen-@i#achs) oder Petroleum, Wachs und Pflanzenfett zu verwenden. Diese neuartigen Schmieren liefern überraschenderweise außerordentlich scharfe Abdrücke und Abgüsse. Sie haben sich allen bisher bekannten Formschmieren als überlegen erwiesen. Die feinsteil Verzierungen in den Gipsformen kommen haarscharf heraus. Dabei sind die erforderlichen Stoffe bequem zu erhalten und preiswert.The present invention now teaches, as a mold lubricant in objects, which are supposed to reproduce the design of the shape exactly, mixture of petroleum and Use wax (bees @ i # achs) or petroleum, wax and vegetable fat. These new types of lubrication surprisingly produce extraordinarily sharp impressions and casts. They have proven to be superior to all mold lubricants known to date. The fine decorations in the plaster molds come out very precisely. Are there to obtain the necessary materials conveniently and inexpensively.

Beispielsweise benutzt man ein Gemenge aus ioo Gewichtsteilen Petroleum und io Gewichtsteilen Wachs, oder ioo Gewichtsteilen Petroleum, io Gewichtsteilen Wachs und io Gewichtsteilen Pflanzenfett. Als Pflanzenfett wäre beispielsweise Myrtenfett,Kokosfett., Mohnöl und Japanwachs zu nennen. Der Fettzusatz bewirkt eine größere Sämigkeit der neuen Modellschmiere.For example, a mixture of 100 parts by weight of petroleum is used and 10 parts by weight of wax, or 100 parts by weight of petroleum, 10 parts by weight Wax and 10 parts by weight of vegetable fat. As vegetable fat, for example, myrtle fat, coconut fat., To mention poppy seed oil and Japan wax. The addition of fat makes the new model smear.

Für derartig großeAnwendungsgebiete, wie z. B. die Herstellung von Falzziegeln in Gipspreßformen, kommt die Neuerung natürlich nicht in Betracht. Einerseits behilft man sich hier mit anderen einfacheren Mitteln, wie Bestreuen der Formen mit getrocknetem, pulverigem Torf, anderseits kommt es in diesen Fällen nicht auf unbedingt genaue Abdrücke an, die auch Einzelheiten gut wiedergeben. Letzteres ist aber gerade das Ziel der vorliegenden Erfindung.For such large areas of application as e.g. B. the production of Interlocking tiles in plaster molds, the innovation is of course out of the question. On the one hand one avails oneself here with other simpler means, such as sprinkling the forms with dried, powdery peat, on the other hand it does not arise in these cases it is essential to provide exact prints that also reproduce details well. The latter is but precisely the aim of the present invention.
