Description

Die Erfindung betrifft eine Transportverpackung aus Kunststoff und ein Verfahren zur Herstellung einer Transportverpackung. Transportverpackungen aus Kunststoff sind in verschiedenen Ausführungsvarianten bekannt und haben sich gut bewährt. Einen Problembereich bildet die Verpackung zündfähiger Materialien und deren Lagerung in explosionsgefährdeten Bereichen. Kunststoffverpackungen können durch elektrostatische Aufladung ihrer Oberflächen zu einer Gefährdung führen. Daher ist in der Richtlinie "statische Elektrizität" ZH1/200 der BG Chemie, Abschnitt 7.1.1.4 beispielsweise festgelegt, dass in einer Ex-Zone 1 für Stoffe der Explosionsgruppe II a aufladbare Flächen von 100 cm2 nicht überschritten werden. Elektrostatische leitfähige Teile einschließlich leitfähiger, das heißt, nicht aufladbarer Flüssigkeiten sind daher zu erden.The invention relates to a transport packaging made of plastic and a method for producing a transport packaging. Transport packaging made of plastic is known in various design variants and has proven itself well. One problem area is the packaging of ignitable materials and their storage in potentially explosive areas. Plastic packaging can pose a hazard due to the electrostatic charging of its surfaces. Therefore, in the "Static Electricity" guideline ZH1 / 200 of BG Chemistry, Section 7.1.1.4, it is stipulated, for example, that in an Ex zone 1 for substances in explosion group II a, chargeable areas of 100 cm 2 are not exceeded. Electrostatic conductive parts including conductive, i.e. non-rechargeable liquids must therefore be earthed.

Sollen in Transportverpackungen aus Kunststoff darüber hinaus brennbare Flüssigkeiten oberhalb ihres unteren Explosionspunktes gehandhabt werden, so ist davon auszugehen, dass an der Ummantelung des Gebindes die Anforderung der Zündquellenvermeidung in der Zone 0 zu erfüllen sind. Für Stoffe der Explosionsgruppe II a dürfen dann unabgeschirmte aufladbare Flächen 25 cm2 nicht überschreiten. If flammable liquids above their lower explosion point are to be handled in plastic transport packaging, it must be assumed that the requirements for avoiding ignition sources in zone 0 must be met on the packaging of the container. For substances in explosion group II a, unshielded chargeable areas must not exceed 25 cm 2 .

Um diesen Anforderungen gerecht zu werden, wurden geschlossene metallische Außenbehälter vorgeschlagen, die den Kunststoffbehälter vollständig ummanteln und somit eine ausreichende Erdung ermöglichen. Dies hat jedoch den Nachteil, dass der Befüllungsgrad der Behälter nicht mehr von außen sichtbar ist.In order to meet these requirements, closed metallic Outer container suggested that the plastic container completely sheath and thus allow adequate grounding. However, this has the disadvantage that the degree of filling of the containers is not more is visible from the outside.

Weiterhin wurde ein dehnbarer Sack mit leitfähigem Material vorgeschlagen, der um den Kunststoffbehälter gelegt werden kann. Derartige Umverpackungen sind jedoch teuer und aufwendig in der Handhabung. Außerdem ist es schwierig zu gewährleisten, dass dies bei derartigen dehnbaren Umverpackungen mit Sicherheit aufladbare Flächen von beispielsweise 100 cm2 nicht überschritten werden.Furthermore, a stretchable sack with conductive material has been proposed that can be placed around the plastic container. However, such outer packaging is expensive and complex to use. In addition, it is difficult to ensure that, with such stretchable outer packaging, surely chargeable areas of, for example, 100 cm 2 are not exceeded.

Es wurden auch Kunststoffverpackungen vorgeschlagen, die in einem Metallkäfig angeordnet sind. Die Felder dieses Metallkäfigs liegen beispielsweise unter 100 cm2 und die Befüllungskappe wurde mit Kupfer/Zink-Sinterverfahren leitfähig ausgebildet. Derartige Käfige teilen jedoch im Wesentlichen die Nachteile des zuvor beschriebenen dehnbaren Sackes.Plastic packaging arranged in a metal cage has also been proposed. The fields of this metal cage are, for example, less than 100 cm 2 and the filling cap was made conductive using the copper / zinc sintering process. However, such cages essentially share the disadvantages of the stretchable bag described above.

Letztlich wurde vorgeschlagen, die Kunststoffbehälter mit Rußpartikeln elektrisch leitfähig auszubilden. Eine ausreichende Rußbeimengung führt jedoch dazu, dass der Kunststoffbehälter nicht mehr translozent ist und somit der Füllstand nicht mehr auf einfache Art und Weise von Außen erkennbar ist. Außerdem reduzieren die eingebrachten Pigmente die Haltbarkeit der Behälter und führen insbesondere bei Fallversuchen zu einem Aufreißen der Behälter an der Bindenaht.Ultimately, it was suggested the plastic container with soot particles to be electrically conductive. Adequate soot addition leads however, to the fact that the plastic container is no longer translucent and therefore the level is no longer easy from the outside is recognizable. The pigments introduced also reduce the shelf life the container and lead to a drop test Tear open the container at the weld line.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Transportverpackung aus Kunststoff derart weiterzubilden, dass sie besser in explosionsgefährdeten Bereichen einsetzbar ist.The invention is therefore based on the object of a transport packaging to further develop plastic in such a way that it is better in potentially explosive atmospheres Areas can be used.

Diese Aufgabe wird dadurch gelöst, dass eine gattungsgemäße Transportverpackung elektrisch leitfähige Polymere aufweist.This object is achieved in that a generic transport packaging has electrically conductive polymers.

Elektrisch leitfähige Polymere werden heute beispielsweise als pulverförmige Beimengung vertrieben, die den Kunststoffen zugegeben werden kann. Dies ermöglicht es, Kunststofftransportverpackungen herzustellen, deren Oberfläche eine hohe Leitfähigkeit aufweisen. Vorzugsweise liegt der spezifische Widerstand unter 106 Ohm X Meter. Dies führt dazu, dass die Kunststoffverpackungen nicht mehr mit Metallgittern oder Netzen umgeben werden müssen und auch für explosionsgefährdete Bereiche Kunststoffverpackungen sehr preisgünstig hergestellt werden können.Electrically conductive polymers are sold today, for example, as a powdery admixture that can be added to the plastics. This makes it possible to produce plastic transport packaging whose surface has a high conductivity. The specific resistance is preferably below 10 6 ohm X meters. This means that the plastic packaging no longer has to be surrounded by metal grids or nets, and that plastic packaging can also be produced very inexpensively for potentially explosive areas.

Die Verwendung elektrisch leitfähiger Polymäre bei der Herstellung der Verpackung führt darüber hinaus dazu, dass bei einer Verformung des Tankes die Ableitschicht zwangsläufig immer am Tank angeordnet ist. Sofern in Folge einer Erwärmung sich das Tankvolumen vergrößert, ist dieser Vorteil auch bei einem über den Tank gezogenen Netz gegeben. Sofern sich der Tank jedoch zusammen zieht erhöht sich in der Regel der Abstand zwischen dem über den Tank gezogenen Netz und der Tankaußenwand, so dass eine ordnungsgemäße Ableitung nicht mehr gewährleistet ist. Wenn der Tank jedoch ohne Öffnen eines Luftzuflusses entleert wird, zieht sich der Tank relativ schnell zusammen und es entsteht gerade in diesem Moment die Gefahr einer Explosion in Folge von elektrostatischen Aufladungen.The use of electrically conductive polymers in the manufacture of the Packaging also means that if the Tankes the discharge layer is always arranged on the tank. If the tank volume increases as a result of heating, is this advantage also exists with a network pulled over the tank. If the tank contracts, however, the usually increases Distance between the net drawn over the tank and the outer wall of the tank, so that proper derivation is no longer guaranteed is. However, if the tank is emptied without opening an air flow the tank contracts relatively quickly and it just emerges at this moment the risk of explosion due to electrostatic Charges.

Vorteilhaft ist es, wenn die Kunststoffverpackung ein stabiler Hohlkörper ist. Hohlkörper erlauben es, auf einfache Art und Weise Behälter herzustellen, die beispielsweise für den Transport von Flüssigkeiten geeignet sind. Derartige Behälter werden in großen Stückzahlen für den Transport und die Lagerung explosionsgefährdender Stoffe oder brennbarer Stoffe verwendet.It is advantageous if the plastic packaging is a stable hollow body is. Hollow bodies allow containers to be produced in a simple manner, which, for example, is suitable for the transport of liquids are. Such containers are used in large quantities for transportation and the storage of explosive or flammable substances used.

Insbesondere betrifft die Erfindung Hohlkörper, die ein Volumen von über 450 Liter aufweisen. Dies sind in der Regel 1000 Liter Kunststoffbehälter, die durch die Verwendung der elektrisch leitfähigen Polymere eine Spezialausrüstung zur Vermeidung elektrostatischer Zündgefahren in explosionsgefährdeten Bereichen der Zone 1Gruppe II A erhalten.In particular, the invention relates to hollow bodies that have a volume of over Have 450 liters. These are usually 1000 liter plastic containers, through the use of the electrically conductive polymers Special equipment to avoid electrostatic ignition hazards in potentially explosive atmospheres Areas of Zone 1Group II A preserved.

Vorteilhafter Weise werden derartige Transportverpackungen aus Polyethylen hergestellt. Hierbei ist vor allem HDPE zu nennen.Such transport packaging made of polyethylene is advantageous manufactured. HDPE is particularly worth mentioning here.

Bei einer einfachen Herstellungsvarianten werden diese Kunststoffverpackungen aus einem extrudierten Schlauchstück geblasen, wobei der Schlauch an den Trennstellen zusammen gepresst wird. Dadurch entstehen Nahtstellen, die im Hinblick auf die Festigkeit besonders gefährdet sind. Die Erfindung betrifft vor allem Kunststoffverpackungen, die eine Nahtstelle aufweisen, da die elektrisch leitfähigen Polymere die Festigkeit an den Nahtstellen nur unwesentlich beeinträchtigt.In a simple manufacturing variant, these plastic packaging blown from an extruded piece of tubing, the Hose is pressed together at the separation points. This creates Seams that are particularly at risk in terms of strength are. The invention relates primarily to plastic packaging, the one Show interface because the electrically conductive polymers the strength only slightly affected at the seams.

Besonders vorteilhaft ist es, wenn die Polymere als Lack auf die Kunststoffverpackung aufgebracht sind. Dies ermöglicht es im Nahtbereich zwei reine Polymer-Materialien miteinander zu verbinden, ohne dass in diesem Bereich Polymere auftreten, die die Festigkeit der Nahtstelle beeinträchtigen könnte. Der Lack wird vorteilhafter Weise erst nach der Erstellung der Nahtstelle auf den fertigen Kunststoffhohlbehälter aufgebracht.It is particularly advantageous if the polymers are applied as a lacquer to the plastic packaging are upset. This enables it in the seam area to bond two pure polymer materials together without having to In this area, polymers occur that impair the strength of the seam could. The varnish is advantageously only after creation the interface applied to the finished hollow plastic container.

Eine derartige Lackschicht kann auf der Innenseite als auch auf der Außenseite der Kunststoffverpackung aufgebracht werden, insbesondere bei Behältern wird vorgeschlagen, dass die Polymere auf die Außenseite der Kunststoffverpackung aufgebracht sind. Dies führt dazu, dass die Ladung auf der Außenseite der Verpackung abgeleitet wird und erleichtert es, die elektrisch leitfähige Schicht mit einer Erdung zu versehen.Such a lacquer layer can be on the inside as well as on the outside be applied to the plastic packaging, especially at It is proposed that the polymers on the outside of the Plastic packaging are applied. This causes the cargo is derived on the outside of the packaging and makes it easier to to provide an electrically conductive layer with an earthing.

Die Polymere müssen nicht unbedingt als durchgehende ununterbrochene Lackschicht aufgebracht werden, sondern können auch als netzartige Schicht aufgebracht sein. Die Verwendung einer netzartigen Schicht reduziert die Menge der notwendigen Polymere und sorgt für eine Durchsichtigkeit des Behälters. The polymers do not necessarily have to be continuous Lacquer layer can be applied, but can also be used as a net-like Layer be applied. The use of a mesh-like layer is reduced the amount of necessary polymers and ensures transparency of the container.

Eine bevorzugte Ausführungsvariante sieht vor, dass die Polymere als translozente Schicht aufgebracht sind. Eine derartige Schicht erlaubt die Erkennbarkeit des Befüllungsgrades des Behälters, auch wenn der Behälter vollständig von einer Lackschicht überzogen ist.A preferred embodiment provides that the polymers as translucent layer are applied. Such a layer allows Visibility of the degree of filling of the container, even if the container is completely covered with a layer of lacquer.

Positive Ergebnisse sind mit dotierten Polymeren erzielt worden, die aus der Gruppe der konjugierten Kettenmoleküle, wie z. B. der Polyaniline stammen.Positive results have been achieved with doped polymers that are made from the group of conjugated chain molecules, such as. B. the polyanilines come.

Die erfindungsgemäße Aufgabe wird auch mit einem Verfahren zur Herstellung einer Transportverpackung gelöst, bei dem eine Oberfläche einer Kunststoffverpackung einer Flammbehandlung oder einer Koronabehandlung unterzogen wird und die Kunststoffverpackung mit einem elektrisch leitfähigen Polymere enthaltenen Material besprüht wird.The object of the invention is also achieved with a method of manufacture a transport packaging solved, in which a surface of a Plastic packaging for flame treatment or corona treatment undergoes and the plastic packaging with an electrical material containing conductive polymers is sprayed.

Die Flammbehandlung oder die Koronabehandlung sorgt dafür, dass die als Lack aufgebrachte Schicht einen guten Halt auf der Kunststoffoberfläche findet und eine gleichmäßig dünne Lackschicht aufgebracht werden kann. Hierzu wird vor allem das Besprühen vorgeschlagen, da dadurch auch im industriellen Einsatz derartige Transportverpackungen schnell und gleichmäßig behandelt werden können.The flame treatment or the corona treatment ensures that the applied as a layer a good hold on the plastic surface finds and apply a uniformly thin layer of lacquer can. For this purpose, spraying is particularly suggested, since it does Transport packaging of this type is also fast in industrial use and can be treated equally.

Vorteilhaft ist es, wenn die besprühte Transportverpackung in einem Metallkäfig angeordnet wird. Der Metallkäfig kann auf einfache Art und Weise geerdet werden und er stellt sicher, dass eine elektrisch leitfähige Verbindung zwischen der elektrisch leitfähigen Polymere aufweisenden Lackschicht und der Erdung erreicht wird. Außerdem bildet der Metallkäfig einen mechanischen Schutz für die Transportverpackung.It is advantageous if the sprayed transport packaging in a metal cage is arranged. The metal cage can be easily and Way to be grounded and it ensures that an electrically conductive Connection between the electrically conductive polymers Paint layer and grounding is achieved. It also forms the metal cage mechanical protection for the transport packaging.

Ein Ausführungsbeispiel einer erfindungsgemäßen Transportverpackung ist in der Figur dargestellt und wird im folgenden näher erläutert. Es zeigt die einzige Figur eine dreidimensionale Ansicht eines Palettenbehälters.An embodiment of a transport packaging according to the invention is shown in the figure and is explained in more detail below. It shows the only figure is a three-dimensional view of a pallet container.

Der in Figur 1 gezeigte Palettenbehälter 1 ist ein sogenannter Intermediate Bulk Container (IBC), der beispielsweise als 1000 Liter-Kunststoffgebinde zum Transport flüssiger auch zündfähiger Materialien dient. Die Erfindung beschränkt sich jedoch nicht auf derartige Palettenbehälter sondern betrifft auch Kunststofffässer, Kanister aus Kunststoff wie beispielsweise Polyethylen und Polypropylen und offene Verpackungen, insbesondere für explosionsgefährdete Stoffe.The pallet container 1 shown in FIG. 1 is a so-called intermediate Bulk Container (IBC), for example as a 1000 liter plastic container for the transport of liquid and ignitable materials serves. However, the invention is not limited to such pallet containers but also affects plastic drums, plastic canisters such as polyethylene and polypropylene and open packaging, especially for explosive substances.

Der Palettenbehälter 1 besteht im Wesentlichen aus einer Kunststoffblase 2 und einer Palette 3. Die Kunststoffblase 2 ist im vorliegendem Fall aus HDPE hergestellt und die Palette aus Holz. Als Palette eignen sich jedoch auch besonders gut metallische Paletten, da diese die Erdung des Behälters erleichtern.The pallet container 1 essentially consists of a plastic bladder 2 and a pallet 3. The plastic bladder 2 is made in the present case HDPE made and the pallet made of wood. However, are suitable as a pallet also particularly good metallic pallets, since these are the earthing of the container facilitate.

Die Kunststoffblase 2 der Transportverpackung 1 hat an ihrer oberen Seite 4 einen Deckel 5. Dieser Deckel 5 ist aus elektrisch leitfähigen Material hergestellt oder weist elektrisch leitfähige Polymere auf. Hierbei ist die leitfähige Oberfläche des Kunststoffdeckels 5 so auszubilden, dass er mit der Oberfläche der Kunststoffblase 2 in Verbindung kommt, um dadurch geerdet zu sein. An der Unterseite 6 der Kunststoffblase 2 ist ein Auslaß 7 vorgesehen, der eine Befüllung und insbesondere eine Entleerung des Behälters ermöglicht.The plastic bladder 2 of the transport packaging 1 has on its upper side 4 a lid 5. This lid 5 is made of electrically conductive material produced or has electrically conductive polymers. Here is the Form conductive surface of the plastic cover 5 so that it with the surface of the plastic bladder 2 comes into contact thereby to be grounded. At the bottom 6 of the plastic bladder 2 is an outlet 7 provided that the filling and in particular an emptying of the Allows container.

Die Kunststoffblase 2 der Transportverpackung 1 weist an ihrer Außenseite eine Lackschicht 8 auf, die elektrisch leitfähige Polymere enthält. Die Lackschicht ist translozent und leicht grünlich und erlaubt es somit den Füllstand im Behälter von außen zu erkennen. Um die Kunststoffblase 2 herum ist ein Metallkäfig 9 angeordnet, der aus senkrechten Streben 10 und waagerechten Streben 11 und 12 gebildet ist. Dieser Metallkäfig 9 hält die Kunststoffblase 2 fest an der Palette 3 und ist mit einer Erdung (nicht gezeigt) versehbar.The plastic bladder 2 of the transport packaging 1 has on its outside a lacquer layer 8, which contains electrically conductive polymers. The lacquer layer is translucent and slightly greenish and therefore allows it to recognize the level in the container from the outside. To the plastic bubble 2 around a metal cage 9 is arranged, the vertical struts 10th and horizontal struts 11 and 12 is formed. This metal cage 9 holds the plastic bladder 2 firmly on the pallet 3 and is grounded (not shown) accidental.

Bei einer statischen Aufladung der Kunststoffblase 2 wird die Ladung der Oberfläche der Kunststoffblase durch die elektrisch leitfähigen Polymere der aufgebrachten Lackschicht solange weitergeleitet, bis sie mit dem Metallkäfig 9 in Berührung kommt. Über den Metallkäfig 9 wird die Ladung anschließend abgeleitet, da der Metallkäfig 9 mit einer Erdung versehen ist. Der Deckel 5 und der Auslasshahn 7 sind entweder elektrisch leitend mit der äußeren Oberfläche der Kunststoffblase 2 verbunden oder stehen direkt mit dem Metallkäfig 9 in Verbindung, um auch in diesen Bereichen eine elektrische Aufladung zu vermeiden. With a static charge of the plastic bladder 2, the charge of Surface of the plastic bubble through the electrically conductive polymers the applied layer of paint is passed on until it with the metal cage 9 comes into contact. The charge is on the metal cage 9 subsequently derived because the metal cage 9 is provided with an earth is. The cover 5 and the outlet tap 7 are either electrically conductive connected to the outer surface of the plastic bladder 2 or stand directly in connection with the metal cage 9 in order also in these areas to avoid electrical charging.

Der aufgebrachte Lack mit elektrisch leitfähigen Polymeren ermöglicht einen spezifischen Widerstand von weniger als 103 Ohm X Meter und gewährleistet somit eine sichere Ableitung elektrostatischer Aufladungen. Der aufgebrachte Lack hat darüber hinaus den Vorteil, dass er den UV-Schutz erhöht, was sich besonders vorteilhaft auf das Füllgut auswirkt.The applied varnish with electrically conductive polymers enables a specific resistance of less than 10 3 Ohm X meters and thus ensures a safe dissipation of electrostatic charges. The applied lacquer also has the advantage that it increases UV protection, which has a particularly advantageous effect on the contents.

Durch Variieren des Anteils von konjugierten Kettenmolekülen im Auftragslack lassen sich spezifische Oberflächenwiderstände von 103 bis 106 Ohm X Meter einstellen.By varying the proportion of conjugated chain molecules in the application varnish, specific surface resistances of 10 3 to 10 6 ohm X meters can be set.
