Description

Verfahren zur Verkittung mehrteiliger elektrischer Isolatoren. Es ist bekannt, daß die mit hydraulischen M itteln,vornehmlich mitZement, zusammengekitteten Isolatoren aus Porzellan oder sonstigen Massen in vielen Fällen dadurch zerstört werden, daß durch die Kittmasse der Isolierstoff gesprengt wird.Method for cementing multi-part electrical insulators. It it is known that those cemented together with hydraulic means, primarily with cement In many cases, this will destroy insulators made of porcelain or other masses be that the insulating material is blown through the putty.

Es ist ferner vorgeschlagen worden, diesem Übelstand dadurch abzuhelfen, daß man den Zement mit gepulverten Schmelzkörpern und Wasser mischt, abbinden läßt und dann durch Erwärmung den Asphalt in die Zementporen treibt.It has also been suggested that this deficiency should be remedied by that the cement is mixed with powdered enamel and water and allowed to set and then by heating it drives the asphalt into the cement pores.

Nach dem vorliegenden Verfahren ist man aber nicht auf ein pulverförmiges Schmelzmittel allein angewiesen, sondern man kann sich auch Schmelzkörper bedienen, die sich in Lösung befinden.According to the present process, however, one is not on a powdery one Flux alone relied on, but you can also use fusible bodies, that are in solution.

So kann man z. B. der Mischung von Zement und Asphaltstaub mehr oder weniger eines Lösungsmittels von Asphalt hinzufügen, z. B. Alkohol, Terpentinöl, Kohlenwasserstoffe, Öl, Lacke o. dgl. Trocknet oder erwärmt man die gekitteten Isolatoren nach dem Abbinden des Zements, so verflüchtigt sich das Lösungsmittel und läßt den vorher festen wie den in Lösung gegangenen Körper in den Poren des Zements zurück.So you can z. B. the mixture of cement and asphalt dust more or add less of a solvent to asphalt, e.g. B. alcohol, turpentine oil, Hydrocarbons, oil, varnish or the like. The cemented insulators are dried or heated after the cement has set, the solvent evaporates and leaves the previously solid and dissolved body back in the pores of the cement.

Man kann auch so verfahren, daß man dem Zement überhaupt keine festen Körper zumischt, sondern ihn mit wässerigen Lösungen anmacht, die zugleich die Bindemittel in einem oder mehreren Lösungsmitteln gelöst enthalten. Mischt man z. B. Zement mit Teerwasser, so läßt man nach dem Erhärten desselben das Wasser und die flüchtigen Teerbestandteile bei der Trocknung bzw. Erwärinung verdunsten. Die zurückbleibenden Kohlenwasserstoffe umlagern dann schützend die Zementbestandteile.One can also proceed in such a way that the cement does not get any solid Mixes the body, but turns it on with aqueous solutions that also act as binders contained dissolved in one or more solvents. If you mix z. B. cement with tar water, after it has hardened, the water and the volatile ones are left Tar components evaporate during drying or heating. The ones left behind Hydrocarbons then protectively rearrange the cement components.

Oder man fügt dem Zementsatz z. B. eine alkalische Lösung von Harzen oder Harzsuspensionen oder Harzseifen zu. Bei der Trocknung oder Erwärmung des abgebundenen Zements wird das Wasser verdunstet. Das durch chemische Reaktionen freizumachende Harz verschmilzt die Kittbestandteile vollständig.Or you add z. B. an alkaline solution of resins or resin suspensions or resin soaps. When drying or heating the set Cement will evaporate the water. That which can be set free by chemical reactions Resin completely fuses the putty components.

Auch Öle und Lacke können benutzt werden, um bei der nachfolgenden Trocknung bzw. Erwärmung die hydraulische Kittmasse als festgewordene Schicht dicht zu umschließen.Oils and varnishes can also be used for the following Drying or heating the hydraulic putty mass as a solid layer tightly to enclose.

Geeignet für einen Schutz der Isolatoren gegen Rissigwerden ist z. B. auch der Ansatz des Zements mit einer ammoniakalische:i Wachs- oder Harzsuspension. Das Ammoniak läßt man nach der Erhärtung des Zements verflüchtigen.Suitable for protecting the insulators against cracking is e.g. B. also the approach of the cement with an ammoniacal: i wax or resin suspension. The ammonia is allowed to evaporate after the cement has hardened.

Dem Kitt kann man beliebige Füllstoffe, z. B. Fasern, Magerungsmittel, leitende Körper, wie Graphit u. dgl., zusetzen, um die mechanische Festigkeit zu erhöhen oder das hydraulische Mittel zu schwächen oder zu stärken, oder um die elektrische Leitfähigkeit des Kittes zu verändern.You can add any fillers to the putty, e.g. B. fibers, lean agents, Add conductive bodies such as graphite and the like to increase mechanical strength increase or weaken or strengthen the hydraulic means, or to make the electric To change the conductivity of the putty.

Es ist zweckmäßig, die Trocknung bzw. Erwärmung zunächst mit niederen Temperaturen vorzunehmen. Sind die flüchtigen Bestandteile ausgetrieben, wendet man vorteilhaft zur vollständigen Verschmelzung und Umlagerung der Kittmasse mit den schwer dissoziierbaren wasserabweisenden Mitteln höhere Wärmegrade an.It is advisable to start the drying or heating with low Temperatures. Once the volatile components have been driven out, turn one advantageous to complete amalgamation and Rearrangement of the Putty compound with water-repellent agents that are difficult to dissociate, higher degrees of warmth at.
