Description

Verfahren zum Herstellen von Gummiüberzügen auf eisernen Gleichrichtergefäßen Es ist bekannt, eiserne Gleichrichtergefäße mit Überzügen aus Gummi zu versehen. Diese Überzüge hat man bisher so hergestellt, daß man auf das Gleichrichtergefäß in plastischem, unvulkanisiertem Zustande mühselig den Gummi, meist in Plattenform, aufbrachte und ihn in einem geschlossenen Kessel unter Druck und bei einer Temperatur von etwa i4o° vulkanisierte. Abgesehen davon, daß ein solches Aufbringen und eine solche Vulkanisation bereits bei kleinen Gleichrichtergefäßen schon umständlich und unvollkommen war, war es bei großen Gleichrichtergefäßen mit erheblichen Schwierigkeiten verbunden, die insbesondere dadurch entstanden, daß die gebräuchlichen Vulkanisierkessel zur Aufnahme, großer Gleichrichtergefäße nicht ausreichten. Die Anschaffung genügend großer Vulkanisierkessel würde derart hohe Kosten verursachen, daß die Herstellung der überzüge aus Gummi sehr unwirtschaftlich werden würde.Method of making rubber coatings on iron rectifier vessels It is known to provide iron rectifier vessels with coatings made of rubber. Up to now, these coatings have been produced in such a way that one is on the rectifier vessel in a plastic, unvulcanized state laboriously the rubber, mostly in plate form, and put it in a closed vessel under pressure and at a temperature vulcanized from about 14o °. Apart from the fact that such an application and a Such vulcanization is already cumbersome with small rectifier vessels and was imperfect, it was with great difficulty with large rectifier vessels connected, which resulted in particular from the fact that the common vulcanizing kettle to accommodate, large rectifier vessels are not sufficient. The acquisition is sufficient large vulcanizing kettles would be so expensive that it would be expensive to manufacture the rubber coatings would become very uneconomical.

Gemäß der Erfindung wird die Vulkanisation von Gummiüberzügen auf eisernen Gleichrichtergefäßen ohne Schwierigkeiten dadurch ermöglicht, daß nacheinander durch Aufspritzen oder Aufstreichen auf das Gefäß zwei Gummilösungen aufgebracht werden, von denen in an sich bekannter Weise die eine Schwefel und die andere einen Ultrabeschleuniger enthält, worauf in an sich ebenfalls bekannter Weise bei niedrigen Temperaturen die Vulkanisation vorgenommen wird. Die Vulkanisation setzt beim Zusammentreffen der beiden Gummilösungen schon bei Zimmertemperatur ein; -um sie jedoch zu beschleunigen, ist es zweckmäßig, sie bei ungefähr 5o°, etwa in einem geheizten gewöhnlichen Trockenraum, vorzunehmen. Man erhält dann einen völlig porenfreien und dicht anliegenden Gummiüberzug mit guter elektrischer Isolationsfähigkeit und hoher Korrosionsbeständigkeit-According to the invention, the vulcanization of rubber coatings on iron rectifier vessels is made possible without difficulty in that two rubber solutions are applied one after the other by spraying or brushing onto the vessel, one of which contains sulfur and the other an ultra-accelerator in a manner known per se Vulcanization is also carried out in a known manner at low temperatures. Vulcanization begins when the two rubber solutions meet at room temperature; - however, in order to accelerate it, it is advisable to carry it out at around 50 °, for example in an ordinary heated drying room. A completely pore-free and tightly fitting rubber coating with good electrical insulation properties and high corrosion resistance is then obtained.
