Perforierte MetallfoliePerforated metal foil
Die Erfindung betrifft eine perforierte Metallfolie aus einem Schwermetall als Filter für Nahrungsmittel, Genußmittel und Körperflüssigkeiten oder als Scherblatt für Trockenrasierer.The invention relates to a perforated metal foil made of a heavy metal as a filter for food, luxury items and body fluids or as a blade for dry razors.
Bestimmte Metalle, die mit Nahrungs- oder Genußmitteln in Berührung kommen, gehen zu einem geringen, jedoch nicht mehr zu vernachlässigenden Prozentsatz in Lösung. Dies kann besonders bei gewissen Schwermetallen gesundheitsschädlich sein, etwa bei Nickel, so daß es erstrebenswert ist, ein derartiges Inlösunggehen zu verhindern. Zu dem Zweck hat man bereits Metallteile von Haushaltsgeräten mit einem überzug aus einem Metall versehen, das nicht so leicht in Lösung geht und/oder nicht gesundheitsschädlich ist, etwa Gold, Platin oder Rhodium. Die Verwendung derartiger Metalle zur Beschichtung von perforierten Metallfolien ist jedoch kostspielig.Certain metals that come into contact with food or luxury foods come, go to a small, but no longer negligible percentage in solution. This can be especially true for certain Heavy metals can be harmful to health, such as nickel, so that it is desirable to prevent such dissolution. For this purpose, metal parts of household appliances have already been provided with a coating made of a metal that is not so easy to get into Solution works and / or is not harmful to health, such as gold, platinum or rhodium. The use of such metals for coating however, perforated metal foils are costly.
Die gleichen ungünstigen Eigenschaften derartiger Schwermetalle ergeben sich auch, wenn die perforierten Metallfolien als medizinische Filter, etwa für Körperflüssigkeiten, verwendet werden. Auch ein Kontakt der Schwermetalle mit der Haut kann zu Allergieerscheinungen führen, beispielsweise bei Nickelscherfolien von Trockenrasiergeräten. Aus diesem Grund werden derartige Scherfolien gewöhnlich mit Platin beschichtet.The same unfavorable properties of such heavy metals also arise when the perforated metal foils are used as medical Filters, for example for body fluids, can be used. Contact of heavy metals with the skin can also lead to symptoms of allergies lead, for example with nickel shaving foils from dry razors. For this reason, such shaving foils usually coated with platinum.
Der Erfindung liegt die Aufgabe zugrunde, eine perforierte Metallfolie der eingangs genannten Art zu schaffen, die bei Berührung mit Nahrungsmitteln, Genußmitteln, Körperflüssigkeiten oder der Haut keine gesundheitlich ungünstigen Wirkungen hat und die trotzdem verhältnismäßig widerstandsfähig ist und nicht so kostspielig wie Edelmetallbeschichtungen.The invention is based on the object of a perforated metal foil of the type mentioned to create that in contact with food, luxury foods, body fluids or the Skin does not have any adverse health effects and is still relatively resistant and not so expensive like precious metal coatings.
Die Lösung dieser Aufgabe ist darin zu sehen, daß die Metallfolie mit einer Schicht einer intermetallischen Verbindung aus Zinn und Nickel überzogen ist» Es hat sich gezeigt, daß eine derartige Beschichtung etwa bei Verwendung als Kaffeefilter, die aus einer Nickelfolie hergestellt sind;, den Anteil des Nickels, der in Lösung geht, um mindestens den Faktor 100 herabsetzt, so daß gesundheitlich unbedenkliche Konzentrationen von Nickel in dem Kaffee erhalten werden.The solution to this problem is to be seen in the fact that the metal foil is coated with a layer of an intermetallic compound of tin and nickel »It has been shown that such a coating for example when used as a coffee filter made of a nickel foil; the proportion of nickel that is in solution goes down by at least a factor of 100, so that concentrations of nickel in the coffee that are harmless to health are obtained will.
Zur Erreichung der günstigen Eigenschaften kann die Schicht eine Dicke von bis zu 25 μπι und vorzugsweise von 0,5 bis 6 μ aufweisen.To achieve the favorable properties, the layer can have a thickness of up to 25 μm and preferably from 0.5 to 6 μm.
Die Schicht kann alternativ aus einer Schmelze oder aus einem galvanischen Bad abgeschieden werden.The layer can alternatively consist of a melt or a galvanic one Bath to be deposited.
Zusätzlich kann die Schicht mit einem Edelmetallüberzug versehen sein. Dieser kann eine sehr geringe Dicke haben, etwa 0,05 bis 0,5 μΐη, da die Schicht aus der intermetallischen Verbindung aus Zinn und Nickel bereits dafür sorgt, daß nur eine unbedeutende Menge des Schwermetalls in Lösung geht.In addition, the layer can be provided with a noble metal coating. This can have a very small thickness, about 0.05 to 0.5 μΐη, since the layer is made up of the intermetallic compound Tin and nickel already ensure that only an insignificant amount of the heavy metal goes into solution.
Eine bevorzugte Anwendung der erfindungsgemäßen Metallfolie aus Nickel besteht in der Verwendung für Kaffeefilter, wobei die Schicht aus Zinn/Nickel eine Dicke von 1 bis 3 μπι hat und ein Überzug aus Gold von 0,05 bis 0,5 μπι Dicke vorgesehen ist.A preferred application of the metal foil according to the invention Nickel is used for coffee filters, the Layer of tin / nickel has a thickness of 1 to 3 μπι and a Plating of gold from 0.05 to 0.5 μm thickness is provided.
Die Erfindung ist im folgenden anhand schematischer Zeichnungen an einem Ausführungsbeispiel ergänzend beschrieben.The invention is described below with reference to schematic drawings an exemplary embodiment described in addition.
Fig. 1 ist eine Draufsicht auf einen Teil einer Filterfolie für Kaffeefilter;Fig. 1 is a plan view of part of a filter sheet for coffee filters;
Fig. 2 ist ein Schnitt längs der Linie II-II von Fig. 1.FIG. 2 is a section along the line II-II of FIG. 1.
Fig. 1 zeigt einen Ausschnitt aus einer perforierten Metallfolie 1, die mit Perforationen 2 versehen ist, welche als Längsschlitze mit einer Breite von 50 bis 100 μπι und einer Länge von etwa 3 mm ausgebildet sind.Fig. 1 shows a section of a perforated metal foil 1, which is provided with perforations 2, which as longitudinal slots with a width of 50 to 100 μm and a length of about 3 mm are trained.
Die Metallfolie besteht aus einer Basisfolie 3 aus Nickel, welche allseitig mit einer Schicht 4 aus einer einphasigen intermetallischen Verbindung von Zinn und Nickel überzogen ist. Der Nickelgehalt dieser Schicht beträgt etwa 35 % und der Zinngehalt dementsprechend 65 %.The metal foil consists of a base foil 3 made of nickel, which is covered on all sides with a layer 4 of a single-phase intermetallic Compound of tin and nickel is coated. The nickel content of this layer is about 35% and the tin content accordingly 65%.
Die Schicht kann auf beliebige Weise auf die Basisfolie 3 aufgebracht sein, etwa aus einem galvanischen Bad. Die Dicke der Schicht 4 beträgt zwischen 1 und 3 μπι . Geringere Schichtdicken als 0,5μπι führen dazu, daß zuviel Nickel in Lösung geht und/oder daß die Lebensdauer der Schicht begrenzt ist. Größere Schichtdicken als 6 μπι sind zur Erzielung der günstigen Eigenschaften nicht erforderlich und daher nicht anzustreben, da die Verweilzeit der Basisfolie in dem galvanischen Bad dadurch unnötig lang wird.The layer can be applied to the base film 3 in any desired manner be, for example from a galvanic bath. The thickness of the layer 4 is between 1 and 3 μm. Smaller layer thicknesses than 0.5μπι lead to too much nickel going into solution and / or that the life of the layer is limited. Layer thicknesses greater than 6 μm are not required to achieve the favorable properties and therefore not to be striven for, since the dwell time of the base foil in the electroplating bath becomes unnecessarily long as a result.
Zum galvanischen Auftragen der Zinn/Nickelschicht wird beispielsweise ein Bad verwendet mit folgender Zusammensetzung:For the galvanic application of the tin / nickel layer, for example used a bath with the following composition:
Zinnchlorid (SnCl2-2H2O) 50Tin chloride (SnCl 2 -2H 2 O) 50
zweiwertiges Zinn 25divalent tin 25
Nickelchlorid (NiCl,.6H0O) 250Nickel chloride (NiCl, .6H 0 O) 250
Nickel 60Nickel 60
Ammoniumbifluorid (NH.F.HF) 40 (Ammoniumhydrogenfluo rid)Ammonium bifluoride (NH.F.HF) 40 (ammonium hydrogen fluoride)
Ammoniumhydroxid-Lösung (NH.,35% Sp.gr. 880)Ammonium hydroxide solution (NH., 35% Sp.gr. 880)
35 ml/135 ml / 1
Das Bad wird mit einer Nickelanode betrieben bei einer Temperatur von 70 C und einer Stromdichte von etwa 2,5 A/dm . Die Abscheidegeschwindigkeit beträgt dabei etwa 1 μπι pro Minute.The bath is operated with a nickel anode at a temperature of 70 C and a current density of about 2.5 A / dm. The deposition rate is about 1 μπι per minute.
3H27473H2747
Zum Herstellen der Schicht können jedoch auch beliebige andere bekannte Bäder verwendet werden»However, any other known ones can also be used to produce the layer Baths are used »
Bei Verwendung der Metallfolie als Siebfolie für Kaffeefilter hat sich gezeigt, daß der Anteil von Nickel, das in Lösung geht, falls die Basisfolie aus Nickel besteht, durch die Schicht 4 um den Faktor 100 bis 135 verringert wird gegenüber einer unbehandelten Nickelfolie,When using the metal foil as a sieve foil for coffee filters found that the proportion of nickel that goes into solution, if the base foil consists of nickel, through the layer 4 by the factor 100 to 135 is reduced compared to an untreated nickel foil,
Wie in Fig. 2 durch die gestrichelte Linie angedeutet ist, kann auf die Schicht 4 zusätzlich eine Edelmetallschicht, etwa eine Goldschicht 5 aufgebracht sein» Eine derartige Siebfolie hat den Vorteil, daß die Goldschicht verhältnismäßig dünn sein kann, da sie nicht als Sperrschicht für Nickel zu wirken braucht, sondern lediglich für eine Geschmacksneutralität der Siebfolie sorgen soll sowie in gewissem Umfang für eine zusätzliche antikorrosive Wirkung. Auch läßt sich eine Goldschicht einfacher sauber halten.As indicated in Fig. 2 by the dashed line, a noble metal layer, such as a Gold layer 5 be applied »Such a screen film has the advantage that the gold layer can be relatively thin because it does not have to act as a barrier layer for nickel, but is only intended to ensure that the sieve film is tasteless and to a certain extent for an additional anti-corrosive effect. A gold layer is also easier to keep clean.
Die Erfindung ist nicht auf die Verwendung von Nickel für die Basisfolie beschränkt, sondern kann vielmehr auch bei anderen Metallen verwendet werden, bei denen eine zu große Konzentration in Lebens- oder Genußmitteln bedenklich ist oder die Berührung mit der Haut oder mit Körperflüssigkeiten nachteilig ist.The invention is not limited to the use of nickel for the base foil, but rather can also be used with others Metals are used in which too high a concentration in food or luxury foods is questionable or the contact is detrimental to the skin or body fluids.
Die Basisfolie kann auf verschiedene Weise hergestellt sein, etwa durch Ätzen, Stanzen oder durch Abscheiden aus einem galvanischen Bad.The base film can be made in various ways, such as by etching, stamping or by deposition from a galvanic bath.
