KLASSEGREAT
Gegenstand der Erfindung ist ein Verfahren zur Herstellung einer Emailmasse für Schreibtafeln aus Blech, welche das Auslöschen der Schrift, bei sonst guter Annahme derselben, durch trockenes Abwischen ermöglicht.The invention relates to a method for producing an enamel compound for writing boards made of sheet metal, which the erasure of the writing, with otherwise good acceptance of it, made possible by dry wiping.
Die bekannten Emailmassen für Blechtafeln setzen nach Angabe des Erfinders dem Auslöschen der Schrift einen Widerstand entgegen, der die Anwendung eines nassenAccording to the inventor, the well-known enamel masses for sheet metal are extinguished Scripture opposes a resistance to the application of a wet
ίο Schwammes erforderlich macht. Diesem Übelstande soll dadurch abgeholfen werden, daß man den Emailsätzen einen größeren Gehalt an dem bisher nur als Färbemittel benutzten Kobaltoxyd gibt. Vermischt man nämlich Kobaltoxyd mit nur so viel Pfeifenton, daß dasselbe als Hauptbestandteil überwiegt, so erhält man einen Satz, der beim Einschmelzen ein Email liefert, dessen Oberfläche bei guter Annahme der Schrift zu deren Auslöschung nur des Wischens mit einem trocknen Läppchen oder mit dem trocknen Finger bedarf. Dem aus Kobaltoxyd und Pfeifenton zusammengestellten Satz fügt man als Flußmittel Borax und zur gleichmäßigeren Färbung etwas Mangansuperoxyd hinzu.ίο makes a sponge necessary. This evil is to be remedied by the fact that the enamel sets have a higher content of what was previously only used as a colorant Cobalt oxide there. If you mix cobalt oxide with only so much pipe clay that if the same predominates as the main constituent, then one obtains a rate which, when melted down an email delivers, the surface of which, if the writing is accepted, leads to its erasure only needs to be wiped with a dry cloth or with a dry finger. The set composed of cobalt oxide and pipe clay is added as a flux Borax and a little manganese peroxide for a more even color.
Die Mengenverhältnisse können sich in den nachstehenden Grenzen beweg-en:The proportions can move within the following limits:
Borax 2 bis 7 Teile,Borax 2 to 7 parts,
Kobaltoxyd 7 - 12Cobalt Oxide 7-12
Pfeifenton 1 - 6 -Whistle tone 1 - 6 -
Mangansuperoxyd. . . 1 - 5 - .Manganese superoxide. . . 1 - 5 -.
Ein sehr zweckmäßiges Mischungsverhältnis ist folgendes:A very useful mixing ratio is the following:
Teile Borax, 10 Teile Kobaltoxyd, 4 Teile Pfeifenton, 2 Teile Mangansuperoxyd.Parts borax, 10 parts cobalt oxide, 4 parts pipe clay, 2 parts manganese superoxide.
Man reibt die verschiedenen Massen naß zusammen, läßt trocknen und nimmt durch ein Sieb.The various masses are rubbed together wet, left to dry and taken through a sieve.
Die Herstellung der Schreibtafel durch Emaillieren von Blech vermittels des beschriebenen Satzes wird in bekannter Weise ausgeführt. The production of the writing board by enamelling sheet metal by means of the described The sentence is executed in a known manner.
