Die Erfindung betrifft die Verwendung von Polyethylen-Werkstoffen für die Herstellung von massiven Transport- und Lagerbehältern aber auch für die Herstellung von ausgekleideten Transport- undThe invention relates to the use of polyethylene materials for the production of massive transport and storage containers but also for the production of lined transport and

Weiterhin betrifft die Erfindung die Verwendung dieser Werkstoffe zur Herstellung des Equipments, welches zur Entnahme der Chemikalien aus den Transportbehältern sowie zu deren Befüllung notwendig ist .Storage containers for chemicals, in particular for the transport and storage of high-purity, liquid chemicals for the electronics industry. Furthermore, the invention relates to the use of these materials for the production of the equipment which is necessary for removing the chemicals from the transport containers and for filling them.
Bei der Herstellung von elektronischen Bauelementen werden in vielen Fällen flüssige Chemikalien benötigt, an deren Reinheit höchste Ansprüche gestellt werden. Dieses ist besonders für dieIn the production of electronic components, liquid chemicals are required in many cases, the purity of which places the highest demands. This is especially for those

Reinheit dieser Chemikalien in einem Bereich, bei dem es nicht mehr genügt, die Chemikalien in der geforderten Reinheit herzustellen, sondern es muß auch dafür gesorgt werden, daß beim Transport, während der Lagerung und der Handhabung keine Verunreinigungen mehr in das Produkt gelangen. Andererseits muß die Lager- undPurity of these chemicals in an area where it is no longer sufficient to produce the chemicals in the required purity, but care must also be taken to ensure that no contaminants get into the product during transport, storage and handling. On the other hand, the storage and
Transportsicherheit gewährleistet sein, da einige dieser Chemikalien aufgrund ihrer aggressiven Eigenschaften schwierig zu handhaben und zu lagern sind. Auch sind sie in vielen Fällen toxikologisch nicht unbedenklich oder aufgrund ihrer chemischen Eigenschaften schädlich. Ein unbeabsichtigtes Ausfließen, z. B. aufgrund einerTransport safety can be guaranteed because some of these chemicals are difficult to handle and store due to their aggressive properties. In many cases, they are also not toxicologically safe or harmful due to their chemical properties. Accidental leakage, e.g. B. due to a
Beschädigung des Transportbehälters oder aufgrund vonDamage to the transport container or due to
Undichtigkeiten, hervorgerufen durch die aggressiven Eigenschaften einiger dieser Chemikalien, muß mit hoher Sicherheit ausgeschlossen werden. y Leaks caused by the aggressive properties of some of these chemicals must be excluded with a high degree of certainty. y
Die aterialauswahl für derartige Transportbehälter muß sich aufgrund der Anforderungen an die zu transportierenden Chemikalien in erster Linie danach richten, jegliche Verunreinigungen auszuschließen. Diese Anforderung wird in der Regel von Behältern aus fluorierten oder perfluorierten Werkstoffen oder von Behältern, die mit solchen Werkstoffen ausgekleidet sind, erfüllt. Je nach Anforderungen werden diese Transport- und Lagerbehälter als drucklose Version oder auch als Druckbehälter hergestellt.The choice of materials for such transport containers must be based primarily on the requirements of the chemicals to be transported to exclude any contamination. This requirement is usually met by containers made from fluorinated or perfluorinated materials or from containers lined with such materials. Depending on requirements, these transport and storage containers are manufactured as unpressurized versions or as pressure containers.
Drucklose Behälter dürfen keinem von außen aufgebrachten Innendruck ausgesetzt werden.Unpressurized containers must not be exposed to internal pressure from outside.
Aus solchen Behältern muß die Entnahme der flüssigen Chemikalien ebenfalls drucklos erfolgen, d. h. mit Hilfe von Pumpen. Diese Pumpen weisen zwangsläufig bewegte Teile auf, so daß Verunreinigungen durch im Pumpenbereich entstehenden Abrieb nicht völlig ausgeschlossen werden können.The liquid chemicals must also be removed from such containers without pressure, i. H. with the help of pumps. These pumps inevitably have moving parts, so that contamination from abrasion occurring in the pump area cannot be completely ruled out.
Es ist jedoch insbesondere bei der Verwendung von druckfesten Behältern bekannt, Chemikalien mit Hilfe von Tauchrohren durch Zuführung von inerten Druckgasen zu entnehmen, so daß keine Pumpen benötigt werden und somit kein Abrieb entstehen kann. Aus DE 36 36 886 ist ein Transportbehälter für flüssige, hochreine Chemikalien mit einem zweischaligen Innenbehälter bekannt, dessen innerste Auskleidung aus einem Fluorkunststoff besteht. Dieser Transportbehälter ist durch seinen mehrschaligen Aufbau so dimensioniert, daß er mit einem Druck beaufschlagt werden kann. Nachteilig ist jedoch, daß einerseits zur Herstellung solcher Innenauskleidungen nur spezielle Fluorkunststoffe geeignet sind, die in aufwendigen und daher teuren Verfahren hergestellt werden müssen, und daß andererseits die Verarbeitbarkeit dieser Kunststoffe erschwert ist, da aufgrund der hohen Reinheitsanforderungen an die zu transportierenden Chemikalien dem Kunststoff keine beliebigenHowever, it is known in particular when using pressure-resistant containers to remove chemicals with the aid of immersion tubes by supplying inert compressed gases, so that no pumps are required and therefore no abrasion can occur. DE 36 36 886 discloses a transport container for liquid, high-purity chemicals with a double-shell inner container, the innermost lining of which is made of a fluoroplastic. Due to its multi-layer structure, this transport container is dimensioned so that it can be pressurized. However, it is disadvantageous that on the one hand only special fluoroplastics are suitable for the production of such inner linings, which have to be produced in complex and therefore expensive processes, and on the other hand that these plastics are more difficult to process because the plastic does not have to meet the high purity requirements for the chemicals to be transported any
Verarbeitungshilfsmittel zugesetzt werden können und eineProcessing aids can be added and a
Kontamination durch Werkzeuge und Umwelteinflüsse weitgehend minimiert werden muß..Contamination from tools and environmental influences must be largely minimized.
Bei der Materialauswahl für die Herstellung massiverIn the choice of materials for the production more massive
Transportbehälter muß der polymere Werkstoff neben derThe transport container must have the polymeric material next to the
Beständigkeit gegen mögliches Auslaugen und Verspröden durch zu transportierende Chemikalien zusätzlich sowohl eine ausreichende Steifigkeit als auch eine gewisse Elastizität aufweisen, so daß aus dem Werkstoff hergestellte Behälter gegenüber Druck und Stoß unempfindlich und stabil sind und weder zur Verformung noch zur Rißbildung neigen. Weiterhin müssen diese Materialeigenschaften auf Dauer erhalten bleiben, so daß auch bei längerer Lagerung sowohl die Reinheit der zu transportierenden Chemikalien als auch die Behältereigenschaften erhalten bleiben.Resistance to possible leaching and embrittlement due to chemicals to be transported additionally have both sufficient rigidity and a certain elasticity, so that containers made of the material against pressure and impact are insensitive and stable and tend neither to deform nor to crack. Furthermore, these material properties must be maintained in the long term, so that both the purity of the chemicals to be transported and the container properties are retained even after prolonged storage.
Aufgabe der Erfindung ist es daher, einen geeigneten Werkstoff zur Herstellung von Transportbehältern für flüssige, hochreine Chemikalien und des notwendigen Equipments zur Verfügung zu stellen, der preiswert herzustellen ist, während der Synthese in hoher Reinheit erhalten wird, keine oder nur in sehr geringer Konzentration Polymerisationskatalysatoren enthält, sich in einfacher Weise möglichst ohne Zusatz von Verarbeitungshilfsmitteln verarbeiten läßt, bzw. nur solche Verarbeitungshilfsmittel enthält, die sich im Gebrauch nicht störend auswirken, oder die durch die zu transportierenden Chemikalien nicht aus dem Werkstoff ausgelaugt werden. Aufgabe der Erfindung ist es auch, einen geeigneten polymeren Werkstoff zur Verfügung zu stellen, aus dem sowohl massive Lager- und Transportbehälter für flüssige, hochreine Chemikalien als auch Auskleidungen für entsprechende Behälter, die mit Druck beaufschlagt werden können, herstellbar sind.The object of the invention is therefore to provide a suitable material for the production of transport containers for liquid, high-purity chemicals and the necessary equipment, which is inexpensive to produce, while the synthesis is obtained in high purity, no or only a very low concentration of polymerization catalysts contains, can be processed in a simple manner if possible without the addition of processing aids, or only contains processing aids which do not have a disruptive effect in use or which are not leached out of the material by the chemicals to be transported. The object of the invention is also to provide a suitable polymeric material from which both massive storage and transport containers for liquid, high-purity chemicals and linings for corresponding containers which can be pressurized can be produced.
Die Aufgabe wird erfindungsgemäß gelöst durch die Verwendung von HD-Polyethylen (HD = high density) zur Herstellung von massiven Lager- und Transportbehältern für flüssige, hochreine Chemikalien für die Elektronikindustrie, des dazugehörigen Equipments, sowie von Auskleidungen für entsprechende Behälter, die mit Druck beaufschlagt werden können, und des hierzu benötigten Equipments. Insbesondere wird die Aufgabe gelöst durch die Verwendung von HD- Polyethylen mit einer spezifischen Dichte von 0,940 - 0,970 g/cm3, insbesondere von 0,942 - 0,961 g/cm3.The object is achieved according to the invention by the use of HD polyethylene (HD = high density) for the production of massive storage and transport containers for liquid, high-purity chemicals for the electronics industry, the associated equipment, and linings for corresponding containers which are pressurized and the equipment required for this. In particular, the object is achieved by using HD polyethylene with a specific density of 0.940-0.970 g / cm 3 , in particular 0.942-0.961 g / cm 3 .
Als Werkstoffe für Behälter in denen hochreine Säuren oder Basen transportiert werden sollen kommen nach gängiger Meinung nur Kunststoffe in Frage, die auf fluorierten Kohlenwasserstoffen basieren. Solche Werkstoffe sind beispielsweise Polytetrafluorethylen (PTFE), Perfluor-Alkoxy-Polymere (PFA), Polyvinylidenfluoride (PVDF), oder Poly(ethylen-Chlor-trifluorethylen) (ECTFE) und werden im allgemeinen Sprachgebrauch mit dem bekannten Warenzeichen „Teflon" umschrieben. Für den Fachmann sind unter diese Begriff fallende Kunststoffe gegenüber dem Einfluß von aggressiven Chemikalien, wie besonders starke Säuren oder Basen aber auch gegenüber Temperatueinflüssen unempfindlich. Es handelt sich bei diesen Kunststoffen um teure, und daher nicht wirtschaftliche Materialien.According to current opinion, only materials based on fluorinated hydrocarbons are suitable as materials for containers in which high-purity acids or bases are to be transported. Such materials are, for example, polytetrafluoroethylene (PTFE), perfluoroalkoxy polymers (PFA), polyvinylidene fluorides (PVDF), or poly (ethylene-chloro-trifluoroethylene) (ECTFE) and are generally used with the well-known trademark "Teflon". For the person skilled in the art, this term covers the influence of aggressive chemicals, such as particularly strong acids or bases but also insensitive to temperature influences. These plastics are expensive and therefore not economical.
Versuche haben nun überraschenderweise gezeigt, daß auch nicht fluorierte Kunststoffe zur Herstellung qualitativ hochwertiger Transportbehälter und des dazu gehörenden Equipments, wie z. B. Tauchrohre, Teile von Pumpen und Schläuche, für flüssige, hochreine Chemikalien für die Elektronikindustrie verwendet werden können. Als besonders geeignete Werkstoffe für die gewünschte Verwendung haben sich ausgewählte HD-Polyethylene (high density polyethylen) erwiesen, und zwar solche Polyethylene mit einer spezifischen Dichte im Bereich von 0,940 - 0,970 g/cm3, insbesondere von 0,942 - 0,961 g/cm3. Weiterhin zeichnen sich diese Polyethylenqualitäten In der Analyse durch einen besonders niedrigen Gehalt anExperiments have now surprisingly shown that non-fluorinated plastics for the production of high quality transport containers and the associated equipment, such as. B. dip tubes, parts of pumps and hoses, can be used for liquid, high-purity chemicals for the electronics industry. Selected HD polyethylenes (high density polyethylene) have proven to be particularly suitable materials for the desired use, namely those polyethylenes with a specific density in the range from 0.940 to 0.970 g / cm 3 , in particular from 0.942 to 0.961 g / cm 3 . Furthermore, these polyethylene qualities are characterized in the analysis by a particularly low content
Katalysatorresten aus. Daher werden von diesen Werkstoffen im Vergleich zu anderen im Kontakt mit sowohl basischen als auch sauren, hochreinen Chemikalien besonders geringe Mengen ionischer Verunreinigungen abgegeben. Auch werden im Kontakt mit Chemikalien vergleichsweise wenig Partikel durch Wechselwirkungen zwischen den Chemikalien und dem Werkstoff erzeugt. Dieses ist besonders wichtig im Hinblick auf die Verwendung des Werkstoffs für die Herstellung des Equipments zum Befüllen und zur Entnahme der Chemikalien. Diese Werkstoffe sind überraschenderweise sowohl zur Herstellung von Tauchrohren als auch für die Herstellung vonCatalyst residues. For this reason, especially small amounts of ionic impurities are released from these materials compared to others in contact with both basic and acidic, high-purity chemicals. In contact with chemicals, comparatively few particles are generated through interactions between the chemicals and the material. This is particularly important with regard to the use of the material for the manufacture of the equipment for filling and removing the chemicals. Surprisingly, these materials are both for the production of immersion tubes and for the production of
Pumpen geeignet, die für die Entnahme der hochreinen Chemikalien aus drucklosen Transportbehältern und zum Fördern an den Verarbeitungsplatz benötigt werden.Pumps suitable for the removal of high-purity chemicals from unpressurized transport containers and for delivery to the processing station.
Dieses war besonders überraschend, da sich entsprechende andere Polyethylen-Werkstoffe, die bereits seit langen Jahren für den Gefahrguttransport bewährt haben, als nicht geeignet für den Transport und die Lagerung von hochreinen, flüssigen Chemikalien eignen. Im Test wurde bei diesen Kunststoffen sowohl eine zu hoheThis was particularly surprising, since the corresponding other polyethylene materials, which have been used for the transport of dangerous goods for many years, have not been suitable for the Transport and storage of high-purity, liquid chemicals are suitable. In the test, these plastics were both too high

Als besonders geeignete Werkstoffe für den genannten Zweck haben sich Polyethylen-Werkstoffe erwiesen, die von der Firma BASF unter dem Warenzeichen Lupolen im Handel vertrieben werden.Polyethylene materials, which are marketed by the BASF company under the Lupolen trademark, have proven to be particularly suitable materials for the stated purpose.
Insbesondere haben sich in Lagertests aus dieses Gruppe von Polyethylenspezifikationen Werkstofftypen als geeignet erwiesen, die unter den Bezeichnungen Lupolen 6021 D, Lupolen 5021 D, LupolenIn particular, bearing tests from this group of polyethylene specifications have proven suitable as material types, which are known under the names Lupolen 6021 D, Lupolen 5021 D, Lupolen
4261 A Q149, und Lupolen 4261 A Q 135 im Handel erhältlich sind.4261 A Q149, and Lupolen 4261 A Q 135 are commercially available.
Für die erfindungsgemäße Verwendung sind diese Werkstoffe besonders geeignet, weil sie extrudierbar sind, sich aber auch ohne Qualitätsverlust verschweißen lassen. Hierdurch ergibt sich die Möglichkeit, durch Verschweißen von geeigneten Platten aus diesem Werkstoff Behälter in nahezu beliebiger Größe herzustellen. Durch auf einer Seite dieser Platten aufgebrachtes, und im Werkstoff verankertes Textilgewebe, ist es möglich, relativ dünnwandige Innenbehälter vorzufertigen. Durch Aufbringen von glasfaserverstärktem Polyesterharz ist es möglich, in sich stabile Behälter herzustellen, die bei entsprechender Auslegung der Druckbehälterverordnung gerecht werden. Im Aufbau weisen diese Behälter folglich eine zweischalige Bauweise auf. Insbesondere handelt es sich dabei um miteinander verbundene Schalen, wobei die innere Schale aus dem erfindungsgemäß ausgewählten HD- Polyethylen besteht und die äußere Schale aus einem glasfaserverstärkten Polyesterharz. Weiterhin ist es möglich die Oberfläche der hergestellten Behälter nach dem Fachmann bekannten Methoden zu modifizieren, beispielsweise durch Lackieren, Kaschieren oder Dispersionsbeschichten mittels geeigneter Sperrpolymere oder durch Beschichten mit dünnen Metallfolien. Für diesen Zweck geeignete Sperrpolymere sind Polyamid, Polyester, Polyvinylidendifluorid oder Polymere auf der Basis von Acrylnitril. Auf diese Weise kann die Durchlässigkeit für Gase, Dämpfe und Flüssigkeiten reduziert werden. Die in den folgenden Tabellen gegebenen Werte sollen die Erfindung näher verdeutlichen, sind aber nicht dazu geeignet, die Erfindung auf die genannten und untersuchten Polyethylen- Werkstoffe mit der Bezeichnung Lupolen zu beschränken These materials are particularly suitable for the use according to the invention because they can be extruded but can also be welded without loss of quality. This results in the possibility of producing containers of almost any size by welding suitable plates from this material. By applying textile fabric to one side of these plates and anchored in the material, it is possible to prefabricate relatively thin-walled inner containers. By applying glass fiber-reinforced polyester resin, it is possible to manufacture stable containers which, if appropriately designed, comply with the Pressure Vessel Ordinance. The construction of these containers consequently has a double-shell construction. In particular, these are interconnected shells, the inner shell consisting of the HD polyethylene selected according to the invention and the outer shell made of a glass fiber reinforced polyester resin. It is also possible to modify the surface of the containers produced by methods known to those skilled in the art, for example by painting, laminating or dispersion coating using suitable barrier polymers or by coating with thin metal foils. Barrier polymers suitable for this purpose are polyamide, polyester, polyvinylidene difluoride or polymers based on acrylonitrile. In this way the permeability to gases, vapors and liquids can be reduced. The values given in the following tables are intended to illustrate the invention in more detail, but are not suitable for restricting the invention to the named and investigated polyethylene materials with the designation Lupolen
