Abstract

Method for coating chemical apparatus utilises synthetic resin-impregnated flat articles, esp. felts or fabrics, composed of carbon or graphite. The flat article is placed on the surface of the chemical apparatus, and cured, either at normal temp. or elevated temp. The flat article can have reactive groups capable of reacting with the synthetic resin during curing. The coated chemical apparatus has good resistance to chemicals and high temps., and the coating is dense and firmly bonded. The carbon or graphite felts/fabrics are formed by carbonising felts/fabrics composed of wool, cellulose, polyamide or polyacrylonitrile fibres. The resin can be an epoxy, phenolic, furane, polyester or polyurethane resin.

  Verfahren zur Beschichtung von chemischen Apparaten und Apparateteilen mit kunstharz imprägnierten, aus   Kohlenstoff-    bzw. Graphitfasern bestehenden Flächengebilden
Aus dem Patent Nr. 475104 ist ein Verfahren zur Beschichtung von chemischen Apparaten und Apparateteilen mit kunstharzimprägnierten, aus Kohlenstoff- bzw.



  Graphitfasern bestehenden Flächengebilden bekannt, welches dadurch gekennzeichnet ist, dass man das Flächengebilde zuschneidet, mit einem langsam kalthärtenden Kunstharz blasenfrei imprägniert, die so imprägnierte Folie auf die vorbereitete Oberfläche des Apparates bzw. Apparateteils aufbringt, bei Normaltemperatur erhärten lässt, die Stossfugen mit einem Kunstharz nachverfugt und bei höherer Temperatur nachhärtet.



   Als Flächengebilde kommen z. B. Kohlenstoff- bzw.



  Graphit-Filz oder -Gewebe in Frage. Es ist möglich, die Oberfläche eines Apparates bzw. Apparateteils aus Eisen durch Sandstrahlen und Vorgrundieren vorzubereiten. Die imprägnierte Folie kann, z. B. mit einer Gummirolle, auf die zu beschichtende Oberfläche aufgerollt werden. Man kann z. B. im Ofen, vorzugsweise im Druckofen, oder auch durch Anheizen des beschichteten Teils in einer schwach sauren Flüssigkeit nachhärten.



   Das Verfahren eignet sich auch zur Reparatur von Reaktionsgefässen, die mit Graphit oder Hartbrandkohle ausgekleidet sind.



   Es hat sich nun gezeigt, dass man bei diesem Verfahren auch heisshärtende Kunstharze verwenden kann und/oder auf das Nachverfugen verzichten kann.



   Ausserdem wurde gefunden, dass die freien Valenzen von in geeigneter Weise hergestellten, z. B. beim Abkühlen nach dem Verkohlen in eine feuchte sauerstoffhaltige Atmosphäre eingebrachten Flächengebilden aus Kohlenstoff-Fasern offenbar mit den funktionellen Gruppen von gewissen Kunstharzen beim Härten zu reagieren vermögen. Das Produkt, nämlich kunstharzimprägniertes Kohlenstoff-Fasermaterial, zeigt im Vergleich zum entsprechenden Kunstharz allein eine erhöhte chemische und thermische Beständigkeit.



   Es ist bekannt, dass elementarer mikrokistalliner Kohlenstoff auf der Oberfläche des kovalent verknüpften Atomverbandes freie Valenzen aufweist, die, z. B.



  durch Sauerstoff, abgesättigt werden können. Es ist auch bekannt, dass die Oberfläche von mikrokirstallinem Kohlenstoff im allgemeinen saure sauerstoffhaltige Gruppen, z. B. Carboxylgruppen oder phenolische Hydroxylgruppen, trägt, welche je nach ihrer Stellung unterschiedliche Acidität zeigen.



   Man kann nun annehmen, dass bei in geeigneter Weise gewählten Imprägnierharzen bei der Härtung eine Verknüpfung zwischen derartigen Gruppen und den funktionellen Gruppen des Kunstharzes zustande kommt; so können z. B. phenolische Hydroxylgruppen mit den entsprechenden Gruppen eines Phenol-Formaldehydharzes in Gegenwart von Protonen reagieren.



   Dass in der Tat eine Umsetzung eintritt, zeigt folgender Versuch: Behandelt man einerseits das Kunstharz, z. B. ein Phenol-Formaldehydharz, für sich (Probe A), anderseits ein mit dem Kunstharz imprägniertes Flächengebilde der oben definierten Art (Probe B) und schliesslich ein Gemisch aus Glasfasern und dem Kunstharz (Probe C) nach dem Härten mit einem Mittel, welches das Harz löst oder abbaut, z. B. heisse Lauge, so löst sich Probe A ohne weiteres; aus Probe C wird das Kunstharz langsamer gelöst; Probe B aber wird nach Entfernung des nicht gebundenen Anteils des Harzes gewichtskonstant, d. h. das gebundene Harz hat eine andere Löslichkeit als das Harz für sich allein.



   Das Verfahren gemäss der Erfindung zur Beschichtung von chemischen Apparaten und Apparateteilen ist dadurch gekennzeichnet, dass man mit Kunstharz imprägnierte, aus Kohlenstoff- bzw. Graphitfasern bestehende Flächngebilde auf die Oberfläche des Apparates bzw. Apparateteils aufbringt und härtet.



   Vorzugsweise verwendet man ein Flächengebilde, das reaktionsfähige Gruppen enthält, die mit dem verwendeten Kunstharz bei der Härtung zu reagieren vermögen. Wenn man kalthärtende Kunstharze verwendet, kann man bei Normaltemperatur erhärten lassen und gegebenenfalls bei höherer Temperatur nachhärten, wäh  rend bei Verwendung heisshärtender Kunstharze bei er   höhter    Temperatur gehärtet werden muss. Die Härtung bzw. Nachhärtung bei erhöhter Temperatur kann z. B.



  im Ofen, vorzugsweise im Druckofen, oder durch Anheizen des beschichteten Teils erfolgen.



   Die auf diese Weise erhaltenen beschichteten Apparate oder Apparateteile sind mit einem aus Kohlenstoffbzw. Graphitfasern bestehenden Flächengebilde, insbesondere einem Kohlenstoff- bzw. Graphit-Filz oder -Gewebe, beschichtet, wobei das Flächengebilde gehärtetes Kunstharz enthält, das vorzugsweise chemisch an das Flächengebilde gebunden ist.



   Als aus Kohlenstoff- bzw. Graphitfasern bestehende Flächengebilde kommen solche in Frage, die durch Verkohlen bzw. Graphitieren von tierischen Fasern, z. B.



  Wolle, pflanzlichen Fasern, z. B. Cellulose, oder Kunstfasern, z. B. Superpolyamide oder Polyacrylnitril, hergestellt sind, oder   Pyrokohlenstoff-Fasem,    die z. B.



  durch Pyrolyse von Kohlenwasserstoffen erhältlich sind.



  Derartige Flächengebilde werden z. B. von der Firma SIGRI Elektrographit GmbH, Meitingen bei Augsburg (Deutschland), hergestellt.



   Als Kunstharze eignen sich z. B. unmodifizierte oder modifizierte Epoxydharze, unmodifizierte oder modifizierte Phenolharze, unmodifizierte oder modifizierte Furanharze, Polyester und Polyurethane. 



  
 



  Process for coating chemical apparatus and apparatus parts with synthetic resin-impregnated flat structures made of carbon or graphite fibers
Patent No. 475104 describes a process for coating chemical apparatus and apparatus parts with synthetic resin-impregnated carbon or



  Graphite fibers are known, which is characterized by the fact that the sheet is cut to size, impregnated with a slowly cold-curing synthetic resin without bubbles, the film impregnated in this way is applied to the prepared surface of the apparatus or part of the apparatus, allowed to harden at normal temperature, the butt joints are grouted with a synthetic resin and post-cures at a higher temperature.



   As fabrics come z. B. carbon or



  Graphite felt or fabric in question. It is possible to prepare the surface of a device or device part made of iron by sandblasting and pre-priming. The impregnated film can, for. B. with a rubber roller, rolled onto the surface to be coated. You can z. B. post-cure in an oven, preferably in a pressure oven, or by heating the coated part in a weakly acidic liquid.



   The process is also suitable for repairing reaction vessels lined with graphite or hard charcoal.



   It has now been shown that hot-curing synthetic resins can also be used in this process and / or post-grouting can be dispensed with.



   It has also been found that the free valences of suitably prepared, e.g. B. when cooling after charring in a moist oxygen-containing atmosphere introduced flat structures made of carbon fibers are apparently able to react with the functional groups of certain synthetic resins during curing. The product, namely synthetic resin-impregnated carbon fiber material, shows increased chemical and thermal resistance compared to the corresponding synthetic resin alone.



   It is known that elementary micro-crystalline carbon on the surface of the covalently linked atomic lattice has free valences which, for. B.



  can be saturated by oxygen. It is also known that the surface of microcrystalline carbon generally contains acidic oxygen-containing groups, e.g. B. carboxyl groups or phenolic hydroxyl groups, which show different acidity depending on their position.



   It can now be assumed that when impregnating resins are suitably selected, a link between such groups and the functional groups of the synthetic resin occurs during curing; so can z. B. phenolic hydroxyl groups react with the corresponding groups of a phenol-formaldehyde resin in the presence of protons.



   The following experiment shows that there is indeed a conversion: If one treats the synthetic resin, e.g. B. a phenol-formaldehyde resin, for itself (sample A), on the other hand a sheet of the type defined above impregnated with the synthetic resin (sample B) and finally a mixture of glass fibers and the synthetic resin (sample C) after curing with an agent which the resin dissolves or degrades, e.g. B. hot lye, sample A dissolves easily; from sample C the resin dissolves more slowly; Sample B, however, becomes constant in weight after removing the unbound portion of the resin, i.e. H. the bound resin has a different solubility than the resin on its own.



   The method according to the invention for coating chemical apparatus and apparatus parts is characterized in that sheet-like structures consisting of carbon or graphite fibers and impregnated with synthetic resin are applied to the surface of the apparatus or apparatus part and cured.



   A flat structure is preferably used which contains reactive groups which are able to react with the synthetic resin used during curing. If you use cold-curing synthetic resins, you can harden at normal temperature and, if necessary, post-cure at a higher temperature, while when using hot-curing synthetic resins it must be cured at a higher temperature. The hardening or post-hardening at elevated temperature can, for. B.



  in an oven, preferably in a pressure oven, or by heating the coated part.



   The coated apparatuses or apparatus parts obtained in this way are coated with a carbon or Flat structure consisting of graphite fibers, in particular a carbon or graphite felt or fabric, coated, the flat structure containing hardened synthetic resin which is preferably chemically bonded to the flat structure.



   As sheet-like structures made of carbon or graphite fibers, those that are produced by charring or graphitizing animal fibers, e.g. B.



  Wool, vegetable fibers, e.g. B. cellulose, or synthetic fibers, e.g. B. superpolyamides or polyacrylonitrile, or pyrocarbon fibers, which z. B.



  can be obtained by pyrolysis of hydrocarbons.



  Such fabrics are z. B. by the company SIGRI Elektrographit GmbH, Meitingen near Augsburg (Germany).



   Suitable synthetic resins are, for. B. unmodified or modified epoxy resins, unmodified or modified phenolic resins, unmodified or modified furan resins, polyesters and polyurethanes.
