Description

Zur Erzeugung hitzebeständiger Überzüge dienende Grundfritte Die Erfindung betrifft einen emailartigen Überzug und ein besonderes Verfahren zur Aufbringung desselben und hat zum Ziele, einen Überzug zu erreichen, der einen ausgezeichneten Schutz gegen eine Oxydation des därunterliegenden Eisens auch bei Temperaturen von 5o0 bis i ioo° C gewährt.Basic frit used to produce refractory coatings. The invention relates to an enamel-like coating and a particular method of application the same and aims to achieve a coating that has an excellent Protection against oxidation of the underlying iron even at temperatures of 50 to 100 ° C granted.

Gemäß der Neuerung wird eine Grundemailfritte bekannter Zusammensetzung, welche neben den üblichen Bestandteilen noch zusätzlich 3 o bis 4o % Quarz und i o bis i q. Ton enthält, unter Zusatz von Nickeloxyd oder Kobaltoxyd in Mengen von 5 bis i o %, gegebenenfalls auch beider Oxyde zusammen, sowie von 5 bis i o % Chromoxyd- in an sich bekannter Weise auf einer Mühle mit genügend Wasser ;gemahlen.According to the innovation, a basic enamel frit of known composition, which, in addition to the usual components, also add 3 o to 4o% quartz and i o to i q. Clay contains, with the addition of nickel oxide or cobalt oxide in quantities of 5 to 10%, if necessary also both oxides together, and from 5 to 10% chromium oxide in a known manner on a mill with enough water; ground.

Zwecks Aufbringung `dieses Überzuges auf eine zweckmäßigerweise in bekannter Weise, z. B. mit einem Sandstrahlgebläse, gereinigte Oberfläche wird die so erhaltene Mischung in nochnassem Zustande auf die zu schützende Oberfläche aufgetragen und; solange sie noch naß ist, mit feinem Quarzsand bestreut. Darauf erfolgt das an sich bekannte Trocknen, vorzugsweise bei Temperaturen von etwa 90o bis iooo° C. Das Aufstreuen des Quarzsandes kann auch beim Einbrennen erfolgen, d. h. solange sich die Masse noch in glühendem Zustande befindet. Der so hergestellte und auf die beschriebene Art aufgebrachte Überzug besitzt die eingangs angegebenen vorteilhaften Eigenschaften. Er ist beliebig anwendungsfähig; insbesondere kommt er in Frage für Glühtöpfe, Zink- und Zinntöpfe und sonstige Behälter, vorzugsweise aus S. M.-Stahlblech, die bei hoher Hitze und starkoxydierenden Gasen erheblichen Korrosionen unterliegen.For the purpose of applying this coating to an expediently in known manner, e.g. B. with a sandblasting blower, the cleaned surface is The mixture thus obtained is applied to the surface to be protected while it is still wet and; as long as it is still wet, sprinkled with fine quartz sand. Then that happens drying known per se, preferably at temperatures of about 90 ° to 100 ° C. The sprinkling of the quartz sand can also take place during the baking process, i. H. so long the mass is still in a glowing state. The so produced and on the described type of applied coating has the advantageous ones mentioned at the beginning Properties. It can be used in any way; in particular, it is suitable for Incandescent pots, zinc and tin pots and other containers, preferably made of S.M. sheet steel, which are subject to considerable corrosion when exposed to high heat and strongly oxidizing gases.
