Description
Die Erfindung betrifft eine Bahn, die von parallel laufenden Kanälen durchsetzt ist und als Halbfertigfabrikat, z.B. zur Herstellung von Wärmeaustauschern, verwendet werden kann.The invention relates to a web which is traversed by channels running in parallel and which can be used as a semi-finished product, for example for the manufacture of heat exchangers.
Die Bahn gemäß der Erfindung ist eine gerippte Kunststoffbahn, die sich dadurch kennzeichnet, dass sie aus einer Folie mit einer Anzahl von parallelen Rippen aus thermoplastischem Kunststoff, die einstückig an die Oberfläche der Folie angeformt sind und eine Gesamtdichte von weniger als 30% der Dichte des Kunststoffs aufweisen, und einer auf die Oberseite der Rippen aufkaschierten Folie besteht.The web according to the invention is a ribbed plastic web, which is characterized in that it consists of a film with a number of parallel ribs made of thermoplastic material, which are integrally formed on the surface of the film and a total density of less than 30% of the density of the Have plastic, and there is a film laminated on top of the ribs.
Zur weiteren Erläuterung der Erfindung wird auf die Zeichnungen Bezug genommen.To further explain the invention, reference is made to the drawings.
Fig. 1 zeigt in perspektivischer Ansicht eine aus thermoplastischem Kunststoff mit parallelen Längsrippen einstückig geformte Bahn.1 shows a perspective view of a web molded in one piece from thermoplastic material with parallel longitudinal ribs.
Fig. 2 ist ein Seitenaufriss der gerippten Kunststoffbahn gemäß der Erfindung.Figure 2 is a side elevation of the corrugated plastic sheet according to the invention.
Fig. 3 ist eine Vorderansicht der in Fig. 2 dargestellten Bahn.FIG. 3 is a front view of the web shown in FIG.
Die Folie 12 ist einstückig mit den parallelen Rippen 16 aus thermoplastischem Kunststoff geformt. Auf die Oberseite der Rippen 16 ist eine Folie 18 aufkaschiert, so dass zwischen den Folien 12 und 18 und den Rippen 16 Kanäle 154 gebildet werden.The film 12 is molded in one piece with the parallel ribs 16 from thermoplastic material. A film 18 is laminated onto the top of the ribs 16, so that channels 154 are formed between the films 12 and 18 and the ribs 16.
Solche Bahnen können hergestellt werden, indem man einen unter Druck stehenden thermoplastischen Kunststoff ohne Druckabfall durch eine seitlich begrenzte Wegstrecke führt, die in einen in druckdichter Verbindung mit einer verhältnismäßig kühlen Oberfläche stehenden Auslass einmündet, wobei die Oberfläche ein zu dem zu erzeugenden Rippenmuster komplementäres Muster aufweist und sich an dem Auslass vorbeibewegt, so dass die Kunststoffschmelze in das Muster hineingetrieben wird und dieses unter Bildung von Rippen ausfüllt, wobei man den Strömungsraum der Kunststoffschmelze über dem mit dem Kunststoff gefüllten Muster auf die Größe der gewünschten Foliendicke eingrenzt, so dass sich eine aus einem Stück mit den entstehenden parallelen Kunststoffrippen bestehende Folie bildet, worauf man das Ganze kühlt und es an einer von dem Auslass entfernt gelegenen Stelle von der Oberfläche entfernt. Auf die so erhaltene, oben offene Bahn wird dann eine Folie, vorzugsweise eine Kunststofffolie, aufkaschiert.Such webs can be produced by leading a pressurized thermoplastic material without pressure drop through a laterally limited path which opens into an outlet in pressure-tight connection with a relatively cool surface, the surface having a pattern complementary to the rib pattern to be produced and moves past the outlet so that the plastic melt is driven into the pattern and fills it with the formation of ribs, the flow space of the plastic melt above the pattern filled with the plastic being limited to the size of the desired film thickness, so that a film consisting of one piece with the resulting parallel plastic ribs is formed, whereupon the whole is cooled and it is removed from the surface at a point remote from the outlet. A film, preferably a plastic film, is then laminated onto the web thus obtained, which is open at the top.
Als thermoplastische Kunststoffe können im Rahmen der Erfindung alle Kunststoffe verwendet werden, die sich in erhitztem, geschmolzenem Zustande unter verhältnismäßig hohen Drücken zu zusammenhängenden, festen Formen Strang pressen lassen. Beispiele für geeignete thermoplastische Kunststoffe sind Polystyrol, hochstoßfestes Polystyrol, ABS-Harz, die gesättigten Kohlenwasserstoffpolymerisate, wie lineares oder verzweigt kettiges Polyäthylen, Polypropylen und Mischpolymerisate derselben, Ionomere, wie sie in den kanadischen Patentschriften 674 595 und 713 631 beschrieben sind, Mischpolymerisate aus Äthylen und alpha,beta-ungesättigten Carbonsäuren, wie sie in der britischen Patentschrift 963 380 beschrieben sind, und Gemische derselben mit gesättigten Kohlenwasserstoffpolymerisaten sowie Gemische, die ein gleichzeitig auskristallisiertes Oxyd oder durch Wasser aktivierte Vernetzungsmittel enthalten, wie sie in der USA-Patentanmeldung Serial No. 248 229 vom 31. Dezember 1962 beschrieben sind, halogenierte oder perhalogenierte Polyolefine, wie Polyvinylchlorid und aus der Schmelze verarbeitbareAs thermoplastics, all plastics can be used in the context of the invention which can be extruded into coherent, solid forms in a heated, molten state under relatively high pressures. Examples of suitable thermoplastics are polystyrene, high-impact polystyrene, ABS resin, saturated hydrocarbon polymers such as linear or branched-chain polyethylene, polypropylene and copolymers of the same, ionomers as described in Canadian patents 674 595 and 713 631, copolymers of ethylene and alpha, beta-unsaturated carboxylic acids, as described in British patent specification 963,380, and mixtures thereof with saturated hydrocarbon polymers and mixtures containing a simultaneously crystallized oxide or crosslinking agent activated by water, as described in US patent application Serial No. 248 229 of December 31, 1962, halogenated or perhalogenated polyolefins, such as polyvinyl chloride and processable from the melt
Polymerisate des Tetrafluoräthylens, wie Mischpolymerisate desselben mit Hexafluorpropylen, und Polymonochlortrifluoräthylen, Polyvinylacetat und Mischpolymerisate desselben mit gesättigten Kohlenwasserstoffpolymerisaten und gegebenenfalls den in der britischen Patentschrift 963 380 beschriebenen sauren Mischpolymerisaten, Polymerisate von alpa,beta-ungesättigten Carbonsäuren, wie Polymethacrylsäuremethylester, die Polyamide, wie Polyhexamethylenadipinsäureamid, Polyhexamethylensebacinsäureamid, Polycaprolactam, Mischpolykondensate derselben und Gemische aus Polyamiden mit sauren Mischpolymerisaten, Ionomeren und/oder gesättigten Kohlenwasserstoffpolymerisaten, Polyoxymethylen und Mischpolymerisate desselben, Polycarbonate, Polyäthylenterephthalat.Polymers of tetrafluoroethylene, such as copolymers of the same with hexafluoropropylene, and polymonochlorotrifluoroethylene, polyvinyl acetate and copolymers of the same with saturated hydrocarbon polymers and optionally the acid copolymers described in British Patent 963 380, the acid copolymers described in British Patent 963, 380, the acid copolymers, such as polyhexa-methylamides, such as polyethylamethylamides, polyethylacrylates, polyethacrylic acid-unsaturated esters, polyethacrylic acid-unsaturated, polyethacrylic acid esters, polyethacrylic acid-methylamethyl esters, polyethylacrylates, polymonochlorotrifluoro-propylene, and polymonochlorotrifluoroethylene , Polyhexamethylene sebacic acid amide, polycaprolactam, mixed polycondensates of the same and mixtures of polyamides with acidic copolymers, ionomers and / or saturated hydrocarbon polymers, polyoxymethylene and copolymers of the same, polycarbonates, polyethylene terephthalate.
Die jeweiligen Verformungstemperaturen richten sich nach dem zu verformenden Kunststoff und nach den Arbeitsbedingungen. Typische Verformungstemperaturen für einige thermoplastische Kunststoffe sind die folgenden: für lineares Polyäthylen 200 bis 250°C; für verzweigt kettiges Polyäthylen 180 bis 190°C; für Polypropylen 200 bis 250°C; für Polystyrol 240 bis 280°C; für Polyvinylchlorid 150 bis 170°C; für Polyhexamethylenadipinsäureamid 260 bis 350°C.The respective deformation temperatures depend on the plastic to be deformed and on the working conditions. Typical deformation temperatures for some thermoplastics are as follows: for linear polyethylene, 200 to 250 ° C; for branched chain polyethylene 180 to 190 ° C; for polypropylene 200 to 250 ° C; for polystyrene 240 to 280 ° C; for polyvinyl chloride 150 to 170 ° C; for polyhexamethylene adipamide 260 to 350 ° C.
Die erfindungsgemäßen Kunststoffbahnen weisen den Vorteil auf, dass sie und infolge dessen auch die aus ihnen hergestellten Fertigerzeugnisse sehr leicht und dabei verhältnismäßig starr sind.The plastic webs according to the invention have the advantage that they, and consequently also the finished products made from them, are very light and at the same time relatively rigid.
