Description
für den chemischen Apparatebau zur Verfügung stehen können. Es besteht daher das dringende Bedürfnis nach anderen korrosionsfesten metallischen Werkstoffen zum Bau von Apparaten, in denen Thioplaste mit guten Eigenschaften hergestellt werden können. may be available for chemical apparatus engineering. There is therefore an urgent need for other corrosion-resistant metallic materials for the construction of apparatuses in which thioplasts with good properties can be produced.
Es wurde nun gefunden, daß unter Verwendung von elektrisch oxydiertem Aluminium Vorrichtungen zur Erzeugung von Thioplasten mit guter Lagerbeständigkeit gebaut werden können. Es ist höchst überraschend, daß dieser Werkstoff den chemischen Einwirkungen widersteht, denen er bei der Thioplastbildung ausgesetzt ist. Denn wenn es auch bekannt war, daß die elektrische Oxydation des Aluminiums zu einer gewissen Erhöhung seiner chemischen Widerstandsfähigkeit führt, so war doch nach den äußerst schlechten Erfahrungen, die man mit Aluminium unter gleichen Bedingungen gemacht hat, mit großer Wahrscheinlichkeit anzunehmen, daß auch das elektrisch oxydierte Metall den Einwirkungen der alkalischen Polysulfidlösung nicht standhalten würde. Wider Erwarten zeigte sich jedoch, daß derartige an sich berechtigte Befürchtungen nicht zutreffen. Auch im Dauerbetrieb tritt selbst an den Rührwerkzeugen aus elektrisch oxydiertem Aluminium keinerlei Korrosion ein. Das geringe spezifische Gewicht des elektrisch oxydierten Aluminiums bietet überdies, insbesondere vor Edelstählen und verchromtem oder vernickeltem Eisen, dem Konstrukteur erhebliche Vorteile.It has now been found that using electrically oxidized Aluminum devices for the production of thioplasts with good storage stability can be built. It is most surprising that this material is the chemical Resists effects to which it is exposed during thioplast formation. Because although it was also known that the electrical oxidation of aluminum to one leads to a certain increase in its chemical resistance, it was after the extremely bad experiences one had with aluminum under the same conditions made to assume with great probability that also the electrically oxidized Metal would not withstand the effects of the alkaline polysulphide solution. Contrary to expectations, however, it turned out that such fears were justified in themselves not true. Even in continuous operation, there is an electrical output even on the stirring tools oxidized aluminum does not corrode. The low specific weight of the Electrically oxidized aluminum also offers, especially before stainless steels and chrome-plated or nickel-plated iron, the designer has considerable advantages.
Man kann den gesamten Apparat zur Herstellung der Thioplaste einschließlich des Gefäßes aus elektrisch oxydiertem Aluminium herstellen bzw. damit auskleiden. Meist verwendet man jedoch ausgemauerte Rührwerkskessel, deren Deckel mit elektrisch oxydiertem Aluminium verkleidet sind und deren Rührwerkzeuge, Heiz- bzw. Kühlschlangen aus elektrisch oxydiertem Aluminium bestehen. Eine derartige Apparatur ist jahrelang zur Herstellung von Thioplasten brauchbar, ohne daß irgendwelche Korrosionserscheinungen auftreten. Die darin hergestellten Thioplaste zeichnen sich vor Erzeugnissen, die aus den gleichen Rohstoffen unter denselben Bedingungen in Apparaten aus Eisen oder Zink hergestellt worden sind, durch erheblich verbesserte Lagerbeständigkeit aus.One can use the entire apparatus for making the thioplasts including of the vessel made of electrically oxidized aluminum or line it with it. Usually, however, brick-lined agitator kettles are used, the lid of which is electrically powered oxidized aluminum and their stirring tools, heating and cooling coils consist of electrically oxidized aluminum. Such an apparatus is for years usable for the production of thioplasts without any signs of corrosion appear. The thioplasts made in it stand out from products that from the same raw materials under the same conditions in apparatus made of iron or Zinc have been made thanks to vastly improved shelf life.
