Description
hinsichtlich der Porenfreiheit, der Haft- und Widerstandsfähigkeit sowie der Beständigkeit der Schutzauskleidungen. Auf diese Weise ist es möglich, Unterkorrosionen unter dem Schutzfilm, wie sie bekanntlich bei angerosteten Eisenflächen auch nach sorgfältiger Reinigung immer wieder vorkommen, mit Sicherheit auszuschliessen. Bei Anwendung der Neuerung auf Eisenteilen ist es mitunter zweckmässig, die zu behandelnenden Oberflächen zunächst mit einem aufgespritzten Überzug aus Zink in einer Stärke von etwa 3oo bis 4oo Mikron zu versehen und ansohliessend den Kunstharz-Überzug aufzubringen. Wie sich nämlich herausgestellt hat, wird die an sich gute Haftfestigkeit der Kunststoffschiebten in dieser Weise weiter merklich erhöht; dieser Befund ist im Hinblick auf die an den schnell bewegten Flügeln auftretenden grossen Abriebwirkungen sowie Schiebe- und Fliehkräfte^, von besonderer Bedeutung. Die erhöhte Haftfestigkeit wird auf eine innige Verzahnung des Kunststoffbelages mit der rauhen und porösen Spritzzinkschicht zurückgeführt.in terms of freedom from pores, adhesion and resistance as well as the resistance of the protective linings. In this way it is possible to have undercorrosion under the protective film like them is known to occur again and again on rusted iron surfaces even after careful cleaning, which can be ruled out with certainty. When applying the innovation to iron parts, it is sometimes useful the surfaces to be treated first with a sprayed-on coating of zinc in a thickness of about 300 to 400 Micron and then apply the synthetic resin coating. As has been found that the inherently good adhesive strength of the plastic slide is further noticeable in this way elevated; this finding is in view of the large abrasion effects occurring on the rapidly moving wings as well as sliding and centrifugal forces ^, of particular importance. The increased adhesive strength is attributed to an intimate interlocking of the plastic covering with the rough and porous spray zinc layer.
Wie mit einer gespritzten Schicht aus Zink lässt sich der gleiche Erfolg durch Aufspritzen anderer Nichteisenmetalle, z.B. von Aluminium oder Blei, erzielen und zwar allein oder in beliebiger Kombination sowie durch gleichzeitigen oder mehrschichtig aufeinander folgenden Auftrag.The same can be done with a sprayed layer of zinc Achieve success by spraying other non-ferrous metals, e.g. aluminum or lead, either alone or in any combination as well as by simultaneous or multi-layer application.
! Als sehr erheblicher Vorteil der nach der Neuerung aufgetragenen \ Schutzüberzüge wurde gefunden, dass sie an ihrer sehr glatten Oberfläche keine Ansetzpunkte für die Abscheidung von festen und von mehr oder minder zähflüssigen Bartikeln aus den fortbewegten Gasen bieten. Solche Abscheidungen führen bekanntlich zu Verengungen der Querschnitte, derart zu Leistungsminderungen und selbst zum vollständigen Versagen der Einrichtungen infolge Verstopfung. In gleicher Weise wie korrosionsbedingte Anfressungen haben Ansätze der beschriebenen Art an Gebläse- oder Ventilatorflügeln gefährliche Unwuchterscheinungen zur Folge; beide Ursachen dieser Gefährdung werden gemeinsam durch die neuartigen Schutzüberzüge ausgeschaltet und so eine erhöhte Betriebssicherheit gewährleistet. ! As a very significant advantage of the applied after the innovation \ protective coatings has been found that they do not provide contact points for the separation of solid and more or less viscous Bartikeln from continuing moving gases at its very smooth surface. It is known that such deposits lead to narrowing of the cross-sections, such to a reduction in performance and even to complete failure of the devices as a result of clogging. In the same way as corrosion-related pitting, approaches of the type described on blower or fan blades result in dangerous imbalance phenomena; Both causes of this hazard are eliminated together by the new protective coatings, thus ensuring increased operational safety.
überraschenderweise bat sieb gezeigt, dass durcb die neuartige Sohutzweise der Wirkungsgrad von Gebläsen und Ventilatoren eine merkliebe Steigerung erfährt und nicht etwa abfällt wie z.B. bei der Anwendung keramischer Überzüge, Vergleichende Beobachtungen ergaben auch bei längeren Betriebszeiten gleichbleibende, um rund 5 % erhöhte Leistungen. Solche Gebläse und Ventilatoren können daher grösseren Dauerbeanspruchungen und erhöhten Spitzenbelastungen ausgesetzt werden und lassen sich auch in Fällen, in denen ein Korrosionsschutz nioht erforderlich ist, mit Vorteil verwenden. Eine Erklärung für die bedeutsame Leistungssteigerung kann ebenfalls in der sehr glatten Oberflächenbeschaffenheit der aufgebrachten Schutz— stoffschichten gesehen werden. Durch diese Eigenschaften werden starke Wirbelungen und grössere Reibungswiderstände an den Oberflächen der Ventilatorflügel und des Gehäuses vermieden, die sich sonst kraftzehrend auf den Antrieb und leistungsmindernd auf die bewegten Gase und Dämpfe auswiken.Surprisingly, sie showed that the efficiency of blowers and ventilators experiences a noticeable increase due to the new type of protection and does not decrease as e.g. with the use of ceramic coatings, comparative observations showed constant, around 5 % increased performance even with longer operating times. Such blowers and ventilators can therefore be exposed to greater continuous loads and increased peak loads and can also be used with advantage in cases in which corrosion protection is not required. An explanation for the significant increase in performance can also be seen in the very smooth surface properties of the protective layers applied. These properties prevent strong eddies and greater frictional resistance on the surfaces of the fan blades and the housing, which would otherwise sap the drive and reduce the performance of the moving gases and vapors.
Ferner hat sich als zweokmässig erwiesen, Zu- und Ableitungen der Ventilatoren und Gebläse, Absaugetrichter, Abscheider, Wärmeaustauscher, Düsen und sonstige zugehörende Einrichtungen wie Kamine und Ableitungen für ausgeschiedene Kondensate ebenfalls in der neuartigen Weise zu schützen und zwar unabhängig davon, ob diese Teile aus metallischen oder nichtmetallischen Werkstoffen gefertigt sind· Dieserart wird zu dem Korrosions- und Gleitschutz durch die Vergütung der inneren Wandoberflächen eine erhöhte Wirtschaftlichkeit erzielt.Furthermore, it has proven to be two-way, inlets and outlets the fans and blowers, suction funnels, separators, heat exchangers, nozzles and other associated equipment such as chimneys and discharges for precipitated condensates are also to be protected in the novel way, regardless of whether they are Parts are made of metallic or non-metallic materials · This is used to protect against corrosion and slide protection Compensation of the inner wall surfaces achieves increased profitability.
