Description
Zinkhaltige Emails oder Glasuren Die Erfindung betrifft Emails oder Glasuren, die als Schmelzüberzüge auf metallischen oder keramischen Formkörpern Verwendung finden.Zinc-containing enamels or glazes The invention relates to enamels or Glazes, which are used as enamel coatings on metallic or ceramic moldings Find use.
Es sind Silikatgläser bekannt, die neben Tonerde die Oxide von Bor, Zink, Zinn, Zirkonium, Cer oder Titan enthalten und die zwischen 500 und 1400°C auf Unterlagen aus keramischem oder metallischem Material aufgebrannt werden und Schmelzüberzüge ergeben. Auch bor- und tonerdefreie Silikatgläser verschiedener Zusammensetzung sind bekannt. Weiter sind sogenannte Schmuckemails bekannt, die für die Dekoration metallischer Unterlagen aus Kupfer dienen, fluorhaltig sind und Zirkoniumdioxid oder Zinndioxid nicht enthalten. Als Trübungsmittel dienen hier Antimon- und Arsenverbindungen.Silicate glasses are known which, in addition to alumina, contain the oxides of boron, Contain zinc, tin, zirconium, cerium or titanium and those between 500 and 1400 ° C are burned onto substrates made of ceramic or metallic material and Enamel coatings result. Also boron-free and alumina-free silicate glasses of various types Composition are known. So-called jewelry enamels are also known that serve for the decoration of metallic substrates made of copper, contain fluorine and Does not contain zirconia or tin dioxide. Serve as opacifiers here Antimony and arsenic compounds.
Bei den genannten Emails oder Glasuren ist die Oberfläche oft nicht stippenfrei und der Wärmeausdehnungskoeffizient ungünstig.In the case of the enamels or glazes mentioned, the surface is often not free of specks and the coefficient of thermal expansion unfavorable.
Die erfindungsgemäßen Emails oder Glasuren werden in erster Linie durch die Verwendung bestimmter Komponenten und festgelegten Mengen erreicht; es entstehen Schmelzüberzüge, die die erwähnten Nachteile nicht aufweisen. Die bekannten Schmuckemails kommen infolge ihres niedrigeren Si02-Gehaltes bis zu 45 Gewichtsprozent für die Eisenemaillierung und als Glasuren auf keramischen Unterlagen nicht in Betracht, da diese die dafür notwendigen Voraussetzungen, z. B. die notwendige Brennstabilität, nicht erfüllen.The enamels or glazes according to the invention are primarily achieved through the use of certain components and specified quantities; it enamel coatings arise that do not have the disadvantages mentioned. The known Decorative enamels have a lower Si02 content of up to 45 percent by weight not suitable for iron enamelling and as glazes on ceramic substrates, since this fulfills the necessary requirements, e.g. B. the necessary combustion stability, not meet.
Die erfindungsgemäßen Emails oder Glasuren sind dadurch gekennzeichnet, daß ein bor- und alkalifreies Email oder eine analoge Glasur aus 35 bis 80 Gewichtsprozent Siliziumdioxid, 1 bis 45 Gewichtsprozent Zinkoxid und ein oder mehreren Alkalioxiden in Mengen von 1 bis 30 Gewichtsprozent besteht.The enamels or glazes according to the invention are characterized by that a boron and alkali-free enamel or an analogous glaze from 35 to 80 percent by weight Silicon dioxide, 1 to 45 weight percent zinc oxide and one or more alkali oxides in amounts of 1 to 30 percent by weight.
Dem das Email oder die Glasur ergebenden Versatz kann auch Tonerde in einer Menge von 1 bis 35 Gewichtsprozent zugegeben werden. Auch ein Zusatz von Zirkonium- und/oder Zinndioxid in Höhe von 1 bis 25 Gewichtsprozent ergibt gute Ergebnisse; das gleiche gilt für Titan- und/oder Cerdioxid, sofern diese in Mengen von 1 bis 20 Gewichtsprozent in den Schmelzflüssen enthalten sind.The offset resulting in the enamel or the glaze can also include clay be added in an amount of 1 to 35 percent by weight. Also an addition of Zirconia and / or tin dioxide at 1 to 25 weight percent gives good results Results; the same applies to titanium and / or ceria, provided these are in quantities from 1 to 20 percent by weight are contained in the melt flows.
Bei Anwesenheit von Zirkonium- und/oder Zinndioxid ist ein weiterer
Zusatz in den Emails oder Glasuren von Fluor in Mengen von 1 bis 15 Gewichtsprozent
vorteilhaft. Beispiele für die Zusammensetzung der Schmelzüberzüge:
Die Ausgangsprodukte werden folgendermaßen zusammengemischt:
Soweit es sich um opake Schmelzüberzüge handelt, ist dem hohen Weißgehalt und den damit verbundenen guten Deckvermögen insofern eine besondere Bedeutung beizumessen, als es auf Grund dieser guten Eigenschaften ohne weiteres möglich ist, farbigen und billigeren keramischen Formkörpern ein erheblich besseres Aussehen zu geben.As far as it is about opaque enamel coatings, the high whiteness is and to attach particular importance to the associated good coverage, than is readily possible due to these good properties, colored and to give cheaper ceramic moldings a significantly better appearance.
In der Emailindustrie werden die zwischen metallischer Unterlage einerseits und opakem Schmelzüberzug andererseits infolge der beim Brand auftretenden ungleichen Spannungen sich bemerkbar machenden Fehler, z. B. Verwerfungen, gleichfalls vermieden.In the enamel industry, those between metallic substrates are on the one hand and opaque enamel coating, on the other hand, due to the uneven appearance of firing Tensions noticeable errors, e.g. B. Distortions, also avoided.
