Description
Verfahren zum Überziehen von Gegenständen durch Aufschleudern zerstäubten; flüssigen Überzugsmaterials. Nach dem Patent 330916 wird staubförmiges und feinkörniges Material vor dem Ausschleudern ohne das Zerstäubungsdruckmittel langsam über erhitzte oder glühende Körper oder durch Kanäle solcher Körper geführt, so daß es gegen die Ausmündung zu immer höher erhitzt bzw. zum Schmelzen gebracht wird. Die Kanäle im Glühkörper sind zweckmäßig in Windungen oder Ecken geführt, damit das Material mit der glühenden Wandung viel in Berührung kommt. Als Bewegungsmittel sollte hauptsächlich die eigene Schwerkraft des Materials dienen, wenn andere, mechanische Transportvorrichtungen vermieden wurden. Es hat sich aber gezeigt, daß staubförmiges Material, je weiter es gegen die Ausmündung des Kanals fortschreitet, infolge der immer größeren Erhitzung auch immer klebriger und massiger wird und überhaupt in erhitztem Zustande nicht leicht nachrückt. Es wurde daher schon bei dem Verfahren nach dem Patent 33o916 feinkörniges oder grießartiges Material dort vorgezogen, wo das Eigengewicht desselben als Bewegungsmittel dienen muß.Process for coating objects by sputtering; liquid coating material. According to the patent 330916, powdery and fine-grained Material slowly overheated before centrifuging without the atomizing pressure medium or glowing bodies, or passed through channels of such bodies, so that it goes against the The mouth is heated to ever higher levels or melted. The channels in the Incandescent bodies are expediently guided in turns or corners so that the material with them the glowing wall comes into much contact. As a means of exercise should mainly the material's own gravity is used when using other, mechanical transport devices were avoided. It has been shown, however, that powdery material, the further it progresses towards the mouth of the canal, as a result of the ever greater heating also becomes more and more sticky and bulky, and not at all when heated easily moves up. It was therefore already used in the process according to patent 33o916 fine-grained or semolina-like material is preferred where its own weight must serve as a means of movement.
Nach dem die vorliegende Erfindung bildenden Verfahren wird das Material in größeren, regelmäßigen Formstücken verwendet, welche geeignet sind, von selbst infolge ihrer eigenen Schwere im Glühkanal nachzurücken. In erster Linie kommen naturgemäß kugelförmige Körper in Betracht. Bei Verwendung kugelförmiger Körper kann der Glühkanal ganz beliebig lang in beliebigen Windungen und Ecken senkrecht abwärts oder schräg abwärts gerichtet sein. Durch die Anwendung eines sehr langen Kanals oder einer sehr langen Bewegungsbahn,wird das Verfahren gemäß dem Patent 33o916 sehr begünstigt. Weniger günstig läßt sich das Verfahren mit würfelförmigen oder anders gestalteten Körpern ausführen, da diese weniger leicht nachrücken und sich im Kanal nicht genügend drehen, wie es für die Ausführung des Verfahrens am günstigsten ist. Doch ist das Verfahren auch mit solchen Körpern ausführbar, wenn der Kanal senkrecht abwärts gerichtet ist und entsprechenden Querschnitt besitzt.According to the process of forming the present invention, the material used in larger, regular fittings which are suitable by themselves to move up in the glow tunnel due to their own gravity. Come first and foremost naturally spherical bodies into consideration. When using spherical bodies the glow tunnel can be of any length in any turns and corners vertically be directed downwards or diagonally downwards. By applying a very long Channel or a very long trajectory, the method according to the patent is used 33o916 very favored. The process with cube-shaped ones can be less favorable or differently designed bodies, as these move up less easily and do not rotate enough in the canal as required to perform the procedure on is cheapest. But the method can also be carried out with such bodies if the channel is directed vertically downwards and has a corresponding cross-section.
Die Anwendung von regelmäßig geformten Körpern aus dem Überzugsmaterial hat für die Ausführung des Verfahrens großen Vorteil. Der Glühkörper, welcher den Durchgangskanal besitzt, muß nicht auf seiner ganzen Länge glühend gehalten werden, sondern es genügt, denselben gut heiß zu halten und nur den untersten Teil kurz vor der Ausmündung, etwa auf die Länge der zwei vordersten Materialkörper, mittels einer kleinen Stichflamme zum Glühen zu bringen. Es kommt dann nur jeweils der vorderste, an der Düsenmündung liegende Körper zum Schmelzen und wird sofort ausgeschleudert, während der nächstfolgende Körper abschmilzt. Dabei wird also jeweils nur so -viel Material geschmolzen, als zerstäubt wird, Lind ein Verstopfen der Düse kann nicht leicht vorkommen. Ferner wird dadurch die Schlackenbildung vermiedeft. Das-,Verfahren eignet sich daher; ganz. hesönders, für leicht oxydierbare Metallw',did"Wi'%hineMen in größerer Menge leicht hart werden und verbrennen, wie z. B. Aluminium.The use of regularly shaped bodies made from the covering material has a great advantage for the execution of the method. The incandescent body, which the Has a passage channel, does not have to be kept glowing along its entire length, but it is enough to keep it well hot and only the lowest part briefly in front of the outlet, approximately to the length of the two foremost material bodies, by means of to glow with a small jet of flame. Then only the foremost comes bodies lying at the nozzle mouth to melt and are immediately ejected, during the next following body melts. So in each case only as much material melted as is atomized, and a clogging of the nozzle can't be easy. This also prevents slag formation. The, procedure is therefore suitable; quite. hesönders, for easily oxidizable metalw ', did "Wi'% eingMen easily harden and burn in large quantities, e.g. B. aluminum.
