Description
Verfahren zum Herstellen von Heizkörpern für elektrische Koch- und Heizgeräte In dem Patent 693 5 16 ist :ein. Verfahren zum Herstellen von Heizkörpern für elektrische Koch- und Heizgeräte beschrieben, nach welchem angefeuchtetem Magnesium.-,Oxyd (Magnesia, bzw. Magnesit) Sauerstoffverbindungen des Bors oder deren Metallsalze oder Kieselsäure in, fester Form in Mengen von o;2 bis q. Gewichtsprozent zugemischt werden,. Nach der Erfindung wer-,den, der Magnesia bzw. dem Magnesit Vanadiumpentoxyd, Baryumoxyd, Phosphorpent-@oxyd und Strontiumolxydeinzeln ioder gemeinsam zugemischt und die Mischung nach Einbetten des Heizleiters gepreßt und zum Austreiben der Feuchtigkeit @erhvtzt. Bei allen diesen Stoffen ist festgestellt worden; daß sie, in gewissen Gewichtsprozenten der keramischen Masse zugemischt, die elektrische Leitfähigkeit .der Masse bei den in Frage koanmenden Temperaturen herabsetzen, ohne ,dabei ihre Wärmeleitfähigkeit .einzubüßen.Method of making radiators for electric cooking and heating appliances. In patent 693 5 16 is: a. Process for the production of radiators for electric cooking and heating devices described, according to which moistened magnesium .-, oxide (magnesia, or magnesite) oxygen compounds of boron or their metal salts or silicic acid in, solid form in amounts of o; 2 to q. Weight percent are added. According to the invention, the magnesia or magnesite vanadium pentoxide, barium oxide, phosphorus pentoxide and strontium oxide are mixed individually or together and the mixture is pressed after embedding the heating conductor and heated to expel the moisture. It has been established for all of these substances; that they, added to the ceramic mass in certain percentages by weight, reduce the electrical conductivity of the mass at the temperatures in question without losing their thermal conductivity.
Diese Sanerstoffverbindurngen: Vanadiümpentoxyd, Baryumqxyd, Phospho@rpentDxyd und Strontiumoxyd können der keramischen Masse .einzeln zugesetzt werden und haben dann die Wirkung, daß der elektrische Widerstand der Masse sich erhöht. Es hat sich aber herausgestellt, daß die Vereinigung mehrerer solcher Zusätze eine weitere wesentliche Verbesserung des Isolierwiderstandes hervorruft, d. h. jede -einzelne Komponente führt für sich eine Verbesserung herbei.These sanitary compounds: Vanadiümpentoxyd, Baryumqxyd, Phospho @ rpentDxyd and strontium oxide can be added individually to the ceramic mass and have then the effect of increasing the electrical resistance of the mass. It has but it was found that the union of several such additions is a further essential Improves the insulation resistance, d. H. every single component brings about an improvement in itself.
Für den Erfolg des Zusatzes der genannten Sauerstoffverbindungen ist @es von Biedeutung, daß die Zusätze gewisse Gewichtsprozente der gesamten keramischen Masse nicht überschreiten. Es ist gefunden worden, daß der Widerstand der keramischen Masse am höchsten ist, wenn die Stoffe in Mengen von 0,2 bis q, Gewichtsprozent der keramischen Masse beigemischt werden. Erfindungsgemäß wird der mit den genannten Stoffen vermischten Masse noch Kaolin in Mengen von o,2 bis ¢ Gevrichtsproazent zugesetzt. Es ist an sich bekannt, keramischen Massen, die für elektrische Koch- und Heizgeräte verwendet werden; Kaolin zuzusetzen. Beim vorliegenden Verfahren werden jedoch einer mit den genannten Sauerstoffverbindungen vermischten keramischen Masse o,2 bis q. Gewichtsprozent Kaolin zum Zweck der Erhöhung des Widerstandes der keramischen Masse zugesetzt.For the success of the addition of the oxygen compounds mentioned is It is important that the additives contain certain percentages by weight of the total ceramic Do not exceed the mass. It has been found that the resistance of the ceramic Mass is highest when the substances are in quantities of 0.2 to q percent by weight be added to the ceramic mass. According to the invention with the mentioned Substances mixed mass or kaolin in amounts of 0.2 to ¢ Gevrichtsproazent added. It is known per se, ceramic masses which are used for electrical cooking and heating devices are used; Add kaolin. In the present case however, a ceramic mixed with the oxygen compounds mentioned Mass o, 2 to q. Weight percent kaolin for the purpose of increasing resistance added to the ceramic mass.
