Description

Verfahren zum Emaillieren von Gegenständen aus Eisen und anderen Stoffen, insbesondere von eisernen Badewannen Die Erfindung betrifft ein Verfahren zum Emaillieren von Gegenständen aus Eisen und anderen Stoffen, insbesondere von eisernen Badewannen u. dgl., durch Aufstreuen von Puderemail -irx. der Vorrichtung, in welcher der Gegenstand erhitzt wird. Bekanntlich unterscheidet man beim Ernaillierverfahren zwei grundsätzliche Ausführungsarten, und zwar einesteils mittels flüssiger Ernailmasse und andernteils mittels Aufstreuens von Puderemail auf die zu behandelnden Gegenstände. Bei Verwendung flüssiger Emailmasse muß erst ein Bestreichen und dann ein Trocknen stattfinden, worauf der Gegenstand in die Muffel gebracht und zum Einbrennen der Emailmasse erhitzt werden kann. Bei Verwendung von Pudereinail muß der Gegenstand zuerst in der Muffel auf die nötige Temperatur gebracht und dann aus der Muffel herausgenommen und in rotglühendern Zustande mit Puderemail bestreut werden. Dies Bestreuen läßt sich trotz Verwendung vonDreh-und Schwenktischen aber gewöhnlich nicht in einer Hitze bewirken, da das Aufstreuen nur auf die möglichst waagerechten Flächen erfolgen kann, und zwar auch nur so lange, wie der Gegenstand zum Festhalten des Puders noch eine gewisse Temperatur besitzt. Es muß daher insbesondere bei größeren Gegenständen ein mehrfaches Anwärmen stattfinden, was natürlich umständlich und zeitraubend ist.Process for enamelling objects made of iron and other materials, in particular of iron bathtubs. The invention relates to a method for enamelling of objects made of iron and other materials, in particular iron bathtubs and the like, by sprinkling with powder email irx. the device in which the object is heated. As is well known, a distinction is made between two basic principles in the marking process Types of execution, on the one hand by means of liquid Ernail mass and on the other hand by sprinkling powder enamel on the objects to be treated. Using liquid enamel must first be coated and then dried, whereupon the object is placed in the muffle and heated to burn in the enamel mass can be. When using powder enamel, the object must first be in the muffle brought to the required temperature and then removed from the muffle and placed in red-hot conditions can be sprinkled with powder enamel. This sprinkling can be done in spite of the use of rotating and swiveling tables, but usually not in a heat cause the sprinkling to take place only on surfaces that are as horizontal as possible can, and only as long as the object to hold the powder on has a certain temperature. It must therefore be used especially for larger objects multiple heating takes place, which is of course cumbersome and time-consuming.

Nach dem Verfahren gemäß der Erfindung werden die zu emaillierenden Gegenstände in einer elektrisch beheiztenMuffel, welche während des Aufpuderns des Emails und der Erhitzung wie die bekannten Pudertische geschwenkt und gedreht werden kann, auf die zum Emaillieren erforderliche Temperatur erhitzt und nach abgenommenem Muffeldekkel in der Muffel selbst in einem Arbeitsgang auf allen Flächen mit Email so lange bestreut werden, bis überall genügend Emailmasse aufgebracht und eingebrannt ist. Weil die Erhitzung während des Puderns weitergeht, kühlt der in der Muffel befindliche Gegenstand nicht ab und gestattet da-durch die Einpuderung auf allen Flächen in einer Hitze, wodurch nicht nur der Arbeitsgang beschleunigt, sondern auch noch an Heizung gespart und die Verschmutzungsgefahr verringert wird.According to the method according to the invention, the to be enamelled Objects in an electrically heated muffle, which during the powdering of the Emails and heating can be swiveled and rotated like the well-known powder tables can, heated to the temperature required for enamelling and after removed Muffle cover in the muffle itself in one operation on all surfaces with enamel be sprinkled until enough enamel material has been applied and burned in everywhere is. Because the heating continues during powdering, the one in the muffle cools the object in place and thus allows powdering on all of them Surfaces in a heat, which not only speeds up the process, but saves heating and reduces the risk of soiling.

Es ist zwar zum Ausbessern von Emailwannen bereits vorgeschlagen worden, in einer feststehenden Vorrichtung, in welcher der zu emaillierende Gegenstand durch Heizflammen erhitzt wird, Puderemail aufzustreuen, jedoch kann mit einer solchen Vorrichtung weder eine gleichmäßige Erwärmung noch ein gleichmäßiger vollständiger Überzug erzielt werden.It has already been proposed to mend enamel tubs, in a fixed device in which the object to be enamelled through Heating flames is heated, sprinkle powder enamel, however, can be done with such contraption neither a uniform heating nor a uniform one complete coating can be achieved.
