Description

Emailgranalien als Strahlmittel Bekanntlich läßt sich Email nur auf metallisch reine Oberflächen emaillierfähiger Metalle jeder Art festhaftend und fehlerfrei aufschmelzen. Es gibt eine große Zahl von Verfahren, die, sei es auf mechanischem oder chemischem Wege oder durch Wärmebehandlung, diese Verarbeitungsvoraussetzung anstreben und auch erreichen. Es ist weiter bekannt, daß allen. diesen Verfahren gewisse Nachteile anhaften, die teilweise durch Kombination einzelner Verfahren untereinander oder durch Wiederholungen der Verfahrensabläufe oder ähnliche Maßnahmen, abgewandt werden sollen und die meist hohe Anlage-und Verarbeitungskosten veranlassen. So z. B. bedarf die chemischeReinigung umfangreicherFabrikationseinrichtungen an Beiz-, Koch-, Wässerungs- oder Neutralisationsbädern, dazu Einrichtungen zum Schutz der Gesundheit ebenso wie für die mechanische Oberflächenreinigung, soweit sie durch Quarzsande im Druckluft- oder Schleuderverfahren geschieht. Der bei diesen; Einrichtungen gegebenen Silikosegefa,hr weicht man aus, indem das Strahlmittel Ouarzsand durch Gußeisensande, Gußeisengrieße, gehackten Stahldraht od. dgl. ersetzt wird.Enamel granules as blasting media It is well known that enamel can only be used on metallically pure surfaces of enamelled metals of any kind firmly adhering and Melt flawlessly. There are a large number of procedures that, be it upon mechanical or chemical means or by heat treatment, this processing requirement strive for and achieve. It is further known that all. this procedure there are certain disadvantages, some of which are due to a combination of individual processes with each other or by repeating the procedures or similar measures, should be averted and usually cause high installation and processing costs. So z. B. chemical cleaning requires extensive manufacturing facilities Pickling, boiling, washing or neutralizing baths, plus protective devices the health as well as for the mechanical surface cleaning, as far as it goes through Quartz sand is done using compressed air or centrifugal methods. The one with these; Facilities Given a silicosis vessel, you can evade it by using the ouarz sand blasting agent Cast iron sand, cast iron grit, chopped steel wire or the like. Is replaced.

Für die Vorbereitung zum Emaillieren birgt jedoch diese letztere Methode den Nachteil, daß das aufschlagende Gußeisen- oder Stahlkorn; je nach Abnützungsgrad die Poren der zu emaillierenden Metalloberfläche zuschlägt bzw. als Abrieb Eisenpulver oder Eisenflitter hinterläßt. Zugeschlagene Poren aber heben die erforderliche Oberflächenrauhigkeit auf und stel:l,en die Haftung in Frage, Eisenabrieb wird von der nachfolgenden Emailschmelze leicht aufgeschwemmt und führt zu Emailfehlern und Ausschuß, insbesondere bei lichtfa,rbenen Emails.For the preparation for enamelling, however, this latter method involves the disadvantage that the impacting cast iron or steel grain; depending on the degree of wear the pores of the metal surface to be enamelled slam or iron powder as abrasion or leaves iron tinsel. However, closed pores increase the required surface roughness on and put: l, en the adhesion in question, iron abrasion is from the ensuing enamel melt easily bloated and leads to enamel defects and rejects, especially in the case of light colors Emails.

Demgegenüber wurde gefunden, daß Strahlmittel nach den Grundsätzen des Ema.ilaufbaues erschmolzen und entsprechend den Abstrahlerfordernissen granuliert diese Nachteile überwinden. Die Erfindung bringt den erheblichen Vorteil, daß die Verschleißstaube des Emailstrahlmittels als Rückstände in den Poren oder auf der zu emaillierenden Metalloberfläche verbleiben können, ohne den Emaileinbrand zu stören, weil sie als gleichartiges Material in der Schmelze aufgehen.In contrast, it was found that blasting media according to the principles of the Ema.il structure melted and granulated according to the radiation requirements overcome these disadvantages. The invention has the significant advantage that the Wear dust of the enamel abrasive as residues in the pores or on the the metal surface to be enamelled can remain without the enamel firing interfere because they dissolve in the melt as a material of the same type.

Die Erfindung hat außerdem den Vorteil, daß der entstehende Staub, der ja aus geschmolzenen, also gelösten Silikaten besteht, keine Silikosegefahr bedingt.The invention also has the advantage that the resulting dust, which consists of melted, i.e. dissolved, silicates, no risk of silicosis conditional.

Ein weiterer erheblicher Vorteil der vorliegenden Erfindung ist die Tatsache, daß das Strahlmittel nach seinen Durchläufen durch die Gebläse- oder Schleudereinrichtungen nicht verloren ist, sondern nach, denn eventuellen Ausscheiden der Metallverunreinigungen durch Umschmelzen und Granulieren wiedergewonnen werden kann.Another significant advantage of the present invention is that The fact that the abrasive after it has passed through the blower or spinner is not lost, but after, because of possible excretion of metal impurities can be recovered by remelting and granulating.
