PATENTAMT.PATENT OFFICE.
Unsere Erfindung behandelt ein Verfahren, um Metallgegenstände mit einem Ueberzug aus geschmolzenem Zinn zu versehen, der vor anderen Metallüberzügen auf galvanoplastischem Wege, wie event. Nickel, Kupfer und Messing, den Vorzug hat, viel schwerer zu oxydiren. Mit besonderem Vortheil ist das Verfahren zum Verzinnen von gufseisernen Kochgeschirren und sonstigen Haus- und anderen Geräthen aus Gufseisen anwendbar, weil dadurch der Gebrauch oft gifthaltiger Emaille vermieden und eine weit höhere Feinheit erzielt wird. Das Verfahren kann auch angewendet werden, um architektonische oder sonstige Eisenverzierungen durch den Ueberzug von Zinn etc. vor Rost zu schützen, ohne ihre Formenschärfe zu beeinträchtigen, wie es der übliche OeI- oder Bronzefarbenanstrich häufig thut.Our invention deals with a method of making metal objects with a coating molten tin in front of other metal coatings on electroformed Ways how event. Nickel, copper, and brass, have the merit of being much more difficult to oxidize. The process for tinning cast iron cookware is particularly advantageous and other domestic and other equipment made of cast iron can be used because it allows the The use of poisonous enamel is often avoided and a much higher degree of fineness is achieved. The process can also be used to make architectural or other iron decorations to protect against rust by the coating of tin, etc., without impairing their sharpness of form, as is usual Oil or bronze paint often does.
Um Gufseisen gleichmäfsig mit Zinn überziehen zu können, wird dasselbe, gleichgültig welche Form das Eisen hat, zuerst mit einem dünnen Ueberzuge von chemisch reinem Eisen versehen. Dieser Ueberzug wird auf galvanischem Wege in einem Bade erzeugt, das in folgender Weise bereitet wird.In order to be able to evenly coat cast iron with tin, the same thing becomes indifferent what form the iron has, first with a thin coating of chemically pure iron Mistake. This coating is produced by galvanic means in a bath which is in is prepared in the following way.
In 5 1 Wasser werden ca. 600 g schwefelsaures Eisenoxydul (Eisenvitriol) gelöst. Zu dieser Lösung wird alsdann eine Lösung von ca. 2 400 g kohlensaurem Natron in 5 1 Wasser gesetzt und der entstehende Niederschlag von kohlensaurem Eisenoxydulhydrat durch Zusatz von so viel concentrirter Schwefelsäure in kleinen Portionen gelöst, bis die Flüssigkeit eine grüne Färbung angenommen hat. Das Bad wird hierauf auf ca. 20 1 mit Wasser verdünnt. Blaues Lackmuspapier darf, in das Bad getaucht, nur eine tief weinrothe Färbung er halten, rothes Lackmuspapier sich nicht verändern. In dieses Bad wird der mit dem chemisch reinen Eisenüberzug zu versehende Gegenstand gelegt, demselben gegenüber die Anode aus Gufsschmiedeisen oder eisenhaltigen Erzen gebracht und beide Theile mit den entsprechenden Polen einer Dynamomaschine, elektrischen Batterie oder anderen geeigneten Elektricitätsquelle verbunden. Schon nach kurzer Zeit ist der Gegenstand mit einer Eisenschicht überzogen, deren Stärke von der Länge der Einwirkung des Bades oder der Stärke des elektrischen Stromes abhängt. Der so überzogene Gegenstand wird darauf mit reinem Wasser abgespült, getrocknet und nach Bestreichen mit einer Lösung von Salmiak in Chlorzink oder auch nur mit einer Chlorzinklösung in ein Gefäfs mit geschmolzenem Zinn getaucht. Das Zinn haftet auf der so vorbereiteten Fläche durchaus fest und der Ueberschufs an Zinn kann durch Bürsten oder auf andere Weise entfernt werden.Approx. 600 g of sulfuric acid iron oxide (iron vitriol) are dissolved in 5 liters of water. to this solution then becomes a solution of approx. 2,400 g of carbonate of soda in 5 l of water set and the resulting precipitate of carbonate of iron oxide hydrate by addition of so much concentrated sulfuric acid dissolved in small portions, until the liquid has turned green. The bath is then diluted to approx. 20 liters with water. Blue litmus paper, dipped in the bath, may only be a deep wine-red color hold, red litmus paper don't change. The one with the chemically pure iron coating to be provided, the same opposite the Brought anode of cast iron or ferrous ores, and both parts with the appropriate Poles of a dynamo, electric battery or other suitable source of electricity. Already after For a short time the object is covered with an iron layer, the thickness of which depends on the length the action of the bath or the strength of the electric current depends. The so overdone The object is then rinsed with pure water, dried and after being brushed with a solution of ammonia in zinc chloride or just with a zinc chloride solution immersed in a vessel of molten tin. The tin adheres to the prepared one The surface is quite firm and the excess tin can be removed by brushing or in some other way.
Sollte der zu verzinnende Gegenstand infolge seiner Gröfse oder Complicirtheit der Form sich nicht leicht in geschmolzenes Zinn eintauchen lassen, so kann er in ein galvanisches Bad von Zinn, das sich in jeder Gröfse leicht herstellen läfst, eingetaucht und mit einer Zinnschicht in beliebiger Stärke überzogen werden, welche dann nach Bestreichen entweder mit Chlorzink oder Salmiaklösung durch irgendShould the object to be tinned owing to its size or complexity of form not easily immersed in molten tin, it can in a galvanic one Pewter bath, which can be easily produced in any size, dipped and covered with a layer of pewter can be coated in any thickness, which is then coated with either Zinc chloride or ammonia solution by any
eine Wärmequelle auf einen solchen Hitzegrad gebracht wird, dais das Zinn gleichmäfsig aufschmilzt. a heat source is brought to such a heat level that the tin melts evenly.
Auf dieselbe Art werden Gegenstände aus Blei und anderen Metallen. welche bei dem Aufschmelzen von Zinn infolge Schmelzens ihre Form verlieren wurden, zum Schütze ihrer Form vor dem Verzinnen mit einem Ueberzug aus reinem Eisen versehen.Objects made of lead and other metals are made in the same way. which at that Melting tin as a result of melting lose its shape, to Sagittarius provided their shape with a coating of pure iron before tinning.
Sollen Gegenstände aus Schmied - oder Walzeisen oder solche, die die beschriebene Vorbehandlung, d. h. die Herstellung eines Ueberzuges aus chemisch reinem Eisen nicht erforderlich machen, verzinnt werden, so genügt die sorgfältige Reinigung dieser Gegenstände und die Bestreichung mit einer Lösung von Salmiak in Chlorzink oder auch nur mit einer concentrirten Lösung von Chlorzink, um die Verzinnung vorzunehmen. Dieses Verfahren der Verzinnung verbindet mit dem Vorzug der einfachen Behandlung den der gröfseren Haltbarkeit des Ueberzuges bei billigerer Herstellung, die zum Theil durch die Ersparnifs an Zinn bedingt wird.Shall objects made of forged or rolled iron or those that are described Pretreatment, d. H. the production of a coating from chemically pure iron does not make it necessary to be tinned, careful cleaning of these objects is sufficient and the coating with a solution of ammonia in zinc chloride or even just with one concentrated solution of zinc chloride for tinning. This method tinning combines the advantage of easy handling with that of greater durability of the coating with cheaper production, which is partly due to the savings Tin is conditioned.
