Description

Isolierkörper für elektrische Heizplatten. Es ist bekannt, Isolierkörper für Heizplatten aus Schamotte o. dgl. herzustellen, indem die Isoliermasse um den Widerstand gepreßt wird. So sind beispielsweise durch die britische Patentschrift 13473 vom Jahre 1892 eine ungebrannte Einbettmasse und durch die Schweizer Patentschrift 63313 und die britische Patentschrift 7o29 vom Jahre lgog gebrannte Einbettmassen bekannt geworden.Insulating bodies for electric heating plates. It is known insulators for heating plates made of fireclay o. The like. To produce by the insulating compound around the Resistance is pressed. So are for example by the British patent specification 13473 from 1892 an unfired investment material and by the Swiss patent specification 63313 and British patent specification 7029 from the year lgog fired investments known.

Bei vorliegendem Erfindungsgegenstand handelt es sich um eine neuartige Zusammensetzung der Isoliermasse. Diese besteht etwa im Verhältnis von = : 1 bis 4 : 1 aus gebranntem oder ungebranntem Ton und Klebsand, welche zermahlen und gut gemischt um den Widerstand gebracht werden, wonach bei mäßigen Temperaturen gebrannt bzw. längere Zeit getrocknet wird.The present subject matter of the invention is a novel one Composition of the insulating compound. This is roughly in the ratio of =: 1 to 4: 1 from fired or unfired clay and sticky sand, which grind and good mixed around the resistor, after which fired at moderate temperatures or is dried for a long time.

Zur Erhöhung der Bindekraft kann dem Gemisch etwa bis zu 3o Prozent der Masse noch Wasserglas, Glasmehl, Quarzmehl o. dgl. zugesetzt werden. Nach Angabe der Erfinderin schwindet die Masse bei der Gebrauchshitze infolge ihrer Zusammensetzung nur wenig und hat dabei genügenden mechanischen Zusammenhalt, gute Wärmeleitfähigkeit und hohe elektrische Isolierfähigkeit. Die Herstellung ist dabei einfach und nicht zu kostspielig.To increase the binding force, the mixture can be added up to about 3o percent Water glass, glass powder, quartz flour or the like can be added to the mass. As specified According to the inventor, the mass shrinks at the heat of use due to its composition only a little and has sufficient mechanical cohesion, good thermal conductivity and high electrical insulation properties. The production is simple and not too expensive.
