Description

Wasserglashaltige Isoliermasse zur Isolierung von Dynamo- und Transformatorenblechen Bekannt sind wassergla.slialtige Isoliermassen für Dynamo- und Transformatorenbleche; diese finden bekanntlich als Aufstrichmasse an Stelle aufgeklebten Papiers Verwendung.Insulating compound containing water glass for the insulation of dynamo and transformer sheets Wassergla.slialtige insulating compounds for dynamo and transformer sheets are known; as is known, these are used as a spread instead of glued-on paper.

Die Besonderheit der wasserhaltigen Isoliermasse gemäß der Erfindung besteht darin, daß sie Beimengungen von Jod und Gelatine enthält, wobei auch in weiterer Zusatz von Boras gute Wirkungen zeitigt. Als besonders vorteilhaft bat sich eine Isoliermasse bewährt, die aus einer Mischung von i o kg Wasserglas, 24o g Gelatine und 3849 Borax mit 48g Jod besteht.The peculiarity of the water-containing insulating compound according to the invention is that it contains admixtures of iodine and gelatin, which also produces good effects in further addition of boras. An insulating compound which consists of a mixture of 10 kg of water glass, 24o g of gelatine and 3849 borax with 48 g of iodine has proven to be particularly advantageous.

Die Isoliermasse gemäß der Erfindung ist gegen Feuchtigkeit besonders unempfindlich, was auf den Jodgehalt zurückzuführen ist. Wenn der Jodzusatz fehlt, so geht diese Unempfindlichkeit verloren; der Jodzusatz hat vermutlich zur Folge, daß das Jod bei der Einwirkung auf das Wasserglas in Jodnatrium und in jodsaures Natron durch Anlagerung an das Natrium des Wasserglases umgesetzt wird, und daß die frei werdende Kieselsäure als wasserunlöslicher Körper eine Schutzschicht gegen den Angriff von Feuchtigkeit bzw. Wasser bildet.The insulating compound according to the invention is special against moisture insensitive, which is due to the iodine content. If there is no iodine added, so this insensitivity is lost; the addition of iodine presumably has the consequence that iodine, when acting on the water glass, is converted into sodium iodine and iodic acid Soda is converted by attachment to the sodium of the water glass, and that the released silica as a water-insoluble body forms a protective layer against forms the attack of moisture or water.
