Für die Verarbeitung der Beschichtung ist es vorteilhaft, wenn die Beschichtung als Lack aufgetragen wird, indem der Beschichtung ein Losemittel beigegeben wird. Der Auftrag des Lacks auf die Oberflachen kann dann herkömmlich im For the processing of the coating, it is advantageous if the coating is applied as a lacquer by adding a solvent to the coating. The application of the paint on the surfaces can then be conventional in the
Spritzverfahren oder Tauchverfahren erfolgen. Um eine besonders gute Haftung der Beschichtung bzw. des Lacks zu erreichen kann zwischen Oberflache und Lack eine Grundierung mit einem Haftvermittler oder Füllstoff aufgetragen werden. Zudem kann die Oberflache vor dem Lackieren z. B. durch Sandstrahlen aufgeraut werden um die Haftung zu erhohen. Spraying or dipping process done. In order to achieve a particularly good adhesion of the coating or the paint can be applied between the surface and paint a primer with a primer or filler. In addition, the surface before painting z.

Preferably, surfaces of the machine housing or of accessories or attachments can thus be made Metal, especially aluminum or iron or steel or plastic can be coated.
Die Trocknung des aufgetragenen Lacks erfolgt in zwei The drying of the applied paint takes place in two
Schritten. In einem ersten Trocknungsprozess wird bei einer niedrigeren Temperatur das Losungsmittel des Lacks entfernt. Dafür eignet sich ein Temperaturbereich von etwa 40° Celsius bis 90° Celsius am besten. Anschließend wird in einem zweiten Schritt bei höherer Temperatur die Beschichtung verbacken oder gesintert. Dabei wird abhangig von dem verwendeten Bindemittel und der Oberfläche eine Temperatur im Bereich von 120°Celsius bis zu maximal 450°Celsius eingestellt . Steps. In a first drying process, the solvent of the paint is removed at a lower temperature. For a temperature range of about 40 ° Celsius to 90 ° Celsius is best. Subsequently, the coating is baked or sintered in a second step at a higher temperature. Depending on the binder used and the surface used, a temperature in the range of 120 ° Celsius up to a maximum of 450 ° Celsius is set.
Es ist insbesondere vorgesehen, die Beschichtung für die Oberflachen von automatischen oder manuellen In particular, it is envisaged the coating for the surfaces of automatic or manual
