Description

Verfahren zum Emaillieren von gußeisernen Gegenständen Das Hauptpatent 662 727 betrifft ein Verfahren zum Emaillieren von gußeisernen Gegenständen, bei welchem die verschiedenen Emailschichten in naßvermahlenem Zustand auf die zu ,emaillierenden Flächen aufgebracht werden. Dabei sollen Grund- und Deckemailschichten mit gleichen .oder annähernd gleichen Einbrandtemperaturen gleichzeitig eingebrannt werden. Die Grundemailschicht kaim auch mit mehreren Deckemailschichten zugleich eingebrannt werden. Gegebenenfalls können nach gemeinsamem Einbrennen der Grundemailschicht mit .einer oder mehreren. Deckemailschichten diese Schichten zunächst zum Erhalten gebracht und anschlie-13end eine oder mehrere Deckemailschichten aufgebracht und eingebrannt werden.Process for enamelling cast-iron objects The main patent 662 727 relates to a process for enamelling cast-iron objects in which the various enamel layers are applied in a wet-ground state to the surfaces to be enamelled. The base and top enamel layers should be baked at the same or approximately the same firing temperatures at the same time. The base enamel layer can also be burned in with several top enamel layers at the same time. If necessary, after joint firing of the base enamel layer, one or more. Cover enamel layers these layers are first preserved and then one or more cover enamel layers are applied and baked.

Die Erfindung betrifft eine weitere Ausbildung der in dem Hauptpatent beschriebenen Verfahren. Das Wesen der Erfindung besteht darin, daß nach Aufbringen ,einer Emailschicht und vor Aufbringen einer weiteren Emailschicht die bereits aufgebrachte Schicht so weit angetrocknet wird, bis der Wasserglanz ihrer Oberfläche verschwunden ist.The invention relates to a further development in the main patent described procedure. The essence of the invention is that after application , an enamel layer and, before applying a further enamel layer, the one that has already been applied Layer is dried until the water gloss on its surface has disappeared is.

Diese Maßnahme ist in den Fällen mit besonderem Vorteil anzuwenden, wo die Emailschichten einen verhältnismäßig hohen Wassergehalt aufweisen. In diesen Fällen besteht die Gefahr, daß sich das aufgespritzte Material an einzelnen Stellen des zu emaillierenden Gegenstandes, insbesondere an scharfkantigen Rändern, wieder ablöst. Diese Gefahr wird mit Sicherheit vermieden, wenn man die bereits aufgebrachte Emailschicht so lange trocknen läßt, bis ihre Oberfläche ein stumpfes Aussehen erhält. Dieser Vorgang vollzieht sich im allgemeinen sehr rasch und läßt sich ohne weiteres mit bloßem Auge verfolgen. , Sobald der Wasserglanz .der Oberfläche verschwunden ist, ist die Emailschicht an ihrer Oberfläche trocken. Das Trocknen der Schicht in ihrer ganzen Stärke würde natürlich einen wesentlich größeren Zeitraum in Anspruch nehmen, ist aber keineswegs erforderlich, um die notwendige Haftfähigkeit der Schichten zu erzielen.This measure is to be used with particular advantage in cases where the enamel layers have a relatively high water content. In these In some cases, there is a risk that the sprayed-on material will be in individual places of the object to be enamelled, especially on sharp edges replaces. This danger is definitely avoided by taking the already applied Let the enamel layer dry until its surface takes on a dull appearance. This process generally takes place very quickly and can be easily carried out track with the naked eye. As soon as the water shine on the surface has disappeared the enamel layer is dry on its surface. The drying of the layer in all its strength, of course, it would take a much longer period of time take, but is by no means required to achieve the necessary adhesion of the layers to achieve.
