Description

Elektrischer Isolierkörper. Die Erfindung betrifft einen festen elektrischen Isolierkörper, wie er z. B. für Schaltdosen, Schaltersockel, Schaltertafeln u. dgl. Anwendung findet. Derartige feste elektrische Isolierkörper besehen der Erfindung gemäß aus natürlichem Bimsmehl mit an sich bekannten Bindemitteln und sind in Formen gepreßt und gebrannt. Auf diese Weise wird nicht nur da voller Ersatz der Isolierkörper aus Porzellan, gepreßtem Papier, Marmor, Schiefer o. dgl. erzielt, sondern auch noch der Vorteil der nachträglichen mechanischen Bearbeitung (Nachbohren usw.) und gegenüber verschiedenen der bisher benutzten Stoffe auch der weitere Vorteil des Schutzes gegen das Eindringen von Feuchtigkeit geboten, obwohl Bimsmehl zur Herstellung benutzt wird. Die Herstellung geschieht in der Weise, daß Bimsmehl durch Wasserglas oder Harze oder andere geeignete Bindemittel gebunden, in die für die jeweils herzustellenden Gegenstrände erforderlichen Formen gepreßt, darauf getrocknet und gebrannt wird. Das Erzeugnis hat -einen hohen Grad dielektrischer Festigkeit, der durch Glasuren oder Tränkung noch erhöht werden kann. Auch können. dem Bimsmehl noch Zusätze von gemahlenem Asbest oder Ton gegeben werden.Electrical insulator. The invention relates to a fixed electrical Insulating body, as it is, for. B. for switch boxes, switch bases, switch panels and the like. Applies. Such solid electrical insulating bodies are part of the invention according to natural pumice powder with known binders and are in forms pressed and fired. In this way, not only is there full replacement of the insulating body Made from porcelain, pressed paper, marble, slate or the like, but also nor the advantage of subsequent mechanical processing (re-drilling, etc.) and Compared to various of the substances previously used, there is also the further advantage of Protection against the ingress of moisture is required, although pumice flour is used in production is used. The production is done in such a way that pumice flour through water glass or resins or other suitable binders bound in those for each to be produced The required shapes are pressed against the beaches, then dried and fired. The product has a high degree of dielectric strength thanks to glazes or impregnation can be increased. Also can. additions of pumice powder ground asbestos or clay.
