Description
Preßkopf zur Herstellung eines mehrschichtigen Kunststoffschlauches Zusatz zum Patent: 1 818 Das Hauptpatent betrifft ein Verfahren zur Erzeugung eines mehrschichtigen Kunststoffschlauches, insbesondere eines aus schlauchförmigen Schichten verschiedenen chemischen Aufbaues bestehenden Schlauches, bei dem die einzelnen Schichten aus thermoplastischen Kunststoffen aus zwei oder mehr konzentrisch zueinander gelegenen Ringdüsen ausgepreßt und unmittelbar nach dem Auspressen durch Aneinanderdrücken miteinander verbunden werden.Compression head for the production of a multilayer plastic hose Addition to the patent: 1 818 The main patent relates to a method for producing a multilayer plastic hose, in particular one made of tubular layers different chemical structure of existing hose, in which the individual Layers of thermoplastics made up of two or more concentric to one another located ring nozzles and pressed together immediately after pressing be connected to each other.
Der Vorschlag des Hauptpatentes geht dahin, daß in dem Raum, den zwei einander benachbarte schlauchförmige Schichten vom Austritt aus den Ringdüsen bis zu ihrer Vereinigung miteinander einschließen, ein stark oxydierendes, aktive oder dipolare Moleküle auf den zu verbindenden Oberflächen der Schichten erzeugendes Gas eingebracht oder in diesem Raum ein solches Gas durch Funkenentladung in einem Hochspannungsfeld erzeugt wird.The proposal of the main patent is that in the space, the two adjacent tubular layers from the exit from the ring nozzles to to their union with each other include a strongly oxidizing, active or generating dipolar molecules on the surfaces of the layers to be connected Introduced gas or in this space such a gas by spark discharge in one High voltage field is generated.
Des weiteren betrifft das Hauptpatent einen Preßkopf zur Durchführung des dort vorgeschlagenen Verfahrens; für das gleichzeitige Anpressen mehrerer schlauchförmiger Schichten sind nach dem Vorschlag des Hauptpatentes mindestens zwei Ringdüsen konzentrisch zueinander angeordnet; in den Bereich zwischen zwei einander benachbarter Ringdüsen mündet mindestens ein Auslaß eines Zuleitungskanals für das stark oxydierende Gas, und daneben ist in dem gleichen Bereich noch mindestens ein Auslaß für einen Gasableitungskanal vorgesehen, durch den überschüssiges Gas und gasförmige Reaktionsrückstände abgeführt werden können. Furthermore, the main patent relates to a press head for implementation the procedure proposed there; for pressing several tubular ones at the same time According to the proposal of the main patent, layers are at least two concentric ring nozzles arranged to each other; in the area between two adjacent ring nozzles at least one outlet of a feed channel for the strongly oxidizing gas opens, and next to it there is at least one outlet for a gas discharge duct in the same area provided, discharged by the excess gas and gaseous reaction residues can be.
Der Vorschlag des Hauptpatentes hat sich in der Praxis hervorragend bewährt. Es hat sich indes gezeigt, daß das nach dem Hauptpatent zu gewinnende Produkt dann in seinen Eigenschaften am vorteilhaftesten ist, wenn an die Gaszuleitungen und Gasableitungen zwischen den Ringdüsen ringförmige Verteiler angeschlossen sind. Es ist dann sichergestellt, daß die miteinander zu vereinigenden Schichtoberflächen von dem Behandlungsgas gleichmäßig bestrichen werden und die Haftung zwischen den Schichten über den ganzen Umfang des entstehenden Schlauches gleichmäßig gut ist. Die Gefahr einer Trennung der Schichten voneinander auf der einen Seite und eines Durchbrennens der Schichten auf Grund überstarker lokaler Einwirkung des Behandlungsgases auf der anderen Seite ist vermieden. The proposal of the main patent has worked extremely well in practice proven. It has been shown, however, that the product to be obtained according to the main patent then in its properties is most advantageous when connected to the gas supply lines and gas discharge lines are connected between the ring nozzles, ring-shaped distributors. It is then ensured that the layer surfaces to be united with one another be smeared evenly by the treatment gas and the adhesion between the Layers over the entire circumference of the resulting hose is evenly good. The risk of separation of the layers from each other on the one hand and one Burning through of the layers due to excessive local action of the treatment gas on the other hand is avoided.
Mindestens ein Ringverteiler kann von einem perforierten, zwischen den Ringdüsen angeordneten Ringrohr gebildet sein. Zweckmäßig weisen die Perforabionen dieses Ringrohres nach dem zwischen den aus den Ringdüsen austretenden Schichten gebildeten Ringraum hin. At least one ring distributor can be of a perforated, between the ring nozzles arranged ring tube be formed. The perforabions expediently have this ring tube after between the layers emerging from the ring nozzles formed annulus.
Das Ringrohr kann in einer Ringnut zwischen den Ringdüsen untergebracht sein. Bei dieser Art der Anordnung bietet sich als besonders zweckmäßig eine Lösung an, bei der der eine Ringverteiler von einem perforierten Ringrohr und der andere von der dieses perforierte Ringrohr aufnehmenden Ringnut gebildet ist. Vorzugsweise schließt man das perforierte Ringrohr an die Gaszuleitung und die Ringnut an die Gasableitung an. The annular tube can be accommodated in an annular groove between the annular nozzles be. With this type of arrangement, a solution is particularly expedient in which one ring distributor consists of a perforated ring pipe and the other is formed by the annular groove receiving this perforated annular tube. Preferably one closes the perforated ring pipe to the gas supply line and the ring groove to the Gas discharge on.
Die Zeichnung erläutert die Erfindung. The drawing explains the invention.
Man erkennt einen Preßkopf mit einem Ringkanal für eine erste Schichtl und einem weiteren Ringkanal für eine weitere Schicht 2. Zwischen den Ringkanälen sind eine Zuleitung 4 für ein Behandlungsgas und eine Ableitung 8 für die Abführung überschüssigen Behandiungsgases sowie etwaiger gasförmiger Reaktionsrückstände vorgesehen. Die Zuleitung 4 führt zu einem Ringrohr 9 mit Perforationen 10, die in einen Ringraum 7 zwischen den austretenden Schichten 1 und 2 weisen. Das Ringrohr 9 liegt in einer Ringnut11. Diese Ringnut 11 ist an die Ableitung8 angeschlossen. Die durch die Zuleitung 4 zuströmenden Behandlungsgase werden durch die Perforationen 10 des Ringrohres 9 gleichmäßig auf die zu behandelnden Schichtoberflächen der Schichten 1 und 2 verteilt und durch die Ringnut 11 ebenso gleichmäßig abgezogen. You can see a press head with an annular channel for a first layer and another ring channel for another layer 2. Between the ring channels are a feed line 4 for a treatment gas and a discharge line 8 for the discharge Excess treatment gas and any gaseous reaction residues provided. The supply line 4 leads to an annular pipe 9 with perforations 10, which in an annular space 7 between the exiting layers 1 and 2. The ring tube 9 is in a Ring groove11. This annular groove 11 is connected to the derivative 8. The one through the supply line 4 inflowing treatment gases are through the perforations 10 of the ring tube 9 evenly distributed over the layer surfaces of layers 1 and 2 to be treated and pulled off equally evenly through the annular groove 11.
Im Zentrum des Auspreßkopfes ist eine Druckgaszuleitung 12 zum Aufblasen der zusammengetretenen Schichten 1 und 2 vorgesehen. Durch dieses Aufblasen erfolgt in an sich bekannter Weise das Zusammendrücken der Schichten. In the center of the extrusion head is a compressed gas supply line 12 for inflation of the joined layers 1 and 2 provided. Through this inflation he follows in a manner known per se, the compression of the layers.
