Abstract
Description
Die Erfindung betrifft ein Rohr oder Rohrformstück mit verbesserten Wärmedämm- und/oder Stabilitäts- und Festigkeitseigenschaften sowie ein Verfahren zur Herstellung Rohre oder -formstücke. The invention relates to a pipe or pipe fitting improved thermal insulation and / or stability and Strength properties and a method for Manufacture of pipes or fittings.
Rohe auch aus Kunststoffen und -formstücke sind seit Jahrzehnten im Bauwesen bekannt und werden für Trinkwasserleitungen, Entwässerungsleitungen, Drainagen, Regenfallrohre, Gasleitungen, als elektrische Installations- und Kabelschutzrohre, für Be- und Entlüftungsanlagen, als Transportleitungen für Chemikalien und für viele andere Fälle mehr verwendet. Die Vorteile der Kunststoffrohre liegen in dem schnellen und leichten Verlegen sowie in ihrer Korrosionsbeständigkeit. PE-Rohre lassen sich beispielsweise in großen Längen von einer Rohrtrommel aus verarbeiten. Für Rohre aus PVC hart oder Polyolefinen wird eine Mindestbetriebsdauer von 50 Jahren gefordert. Raw materials made from plastics and fittings have also been around Decades in the construction industry and are known for Drinking water pipes, drainage pipes, drainage, Downpipes, gas pipes, as electrical Installation and cable protection tubes, for loading and Ventilation systems, as transport lines for chemicals and used more for many other cases. The advantages the plastic pipes are quick and easy Laying as well as in their corrosion resistance. PE pipes can be, for example, in long lengths of one Process tube drum from. For pipes made of PVC hard or Polyolefins will have a minimum operating life of 50 years required.
Bei erdverlegten Freispiegelleitungen ist dafür Sorge zu tragen, daß sich bei fachgerechter Verdichtung ein Membranzustand mit Gewölbewirkung einstellt, in dem die Spannungen im Rohr weit unter normgemäß zulässigen Beanspruchungen mit Blick auf die anzustrebende Betriebszeit bleiben. Care must be taken in the case of buried exposed mirror lines wear that with proper compression Membrane state with vault effect sets, in which the Tensions in the pipe are far below the standards permitted Stresses with a view to the target Operating time remain.
Trotz der Vorteile insbesondere bekannter Kunststoffrohr- Materialien sind deren Stabilitäts- und Festigkeitseigenschaften für bestimmte Anwendungsfälle unzureichend, was ebenso für die chemische Beständigkeit, aber auch für ein optimales Wärmedämmverhalten gilt. Despite the advantages of known plastic pipe Materials are their stability and Strength properties for certain applications inadequate, which is also the chemical resistance, but also applies to optimal thermal insulation behavior.
Anorganisches, geschlossenporiges oder geschlossenzelliges Blähglas ist als vorteilhafter Dämmstoff bekannt, der sich durch einen sehr hohen Dämmwert, statische Belastbarkeit und lastabtragende Wirkung auszeichnet. Inorganic, closed-pore or closed-cell Expanded glass is known to be an advantageous insulating material due to a very high insulation value, static resilience and load-bearing effect.
Ausgangsmaterial für Blähglas-Leichtwerkstoff ist aufbereitetes Recyclingglas. Dieses wird zu Glasmehl gemahlen, als Rohgranulat geformt und im Drehrohrofen bei etwa 750 bis 900°C gesintert. Hierbei entsteht eine viskose Glasschicht, die das aufgeblähte Granulat umschließt. Durch spezielle Steuerung erhält das Granulat anschließend seine endgültige Größe, z. B. eingeteilt in vier Standard-Durchmessergruppen von 0,2 bis 0,5 mm, 0,5 bis 1 mm, 1 bis 2 mm und 2 bis 4 mm. Das für Dämmzwecke einzusetzende Blähglas soll eine möglichst gleichmäßige feinporige Struktur und eine weitgehend geschlossene Oberfläche aufweisen. Von Vorteil ist die hohe Formstabilität bis hinein in einen Temperaturbereich von 750°C, die Beständigkeit gegen Frost und die nicht gegebene Brennbarkeit. Mit 190 bis 300 g/l Schüttgewicht ist Blähglas extrem leicht und besitzt eine hohe Druckfestigkeit im Bereich von 12 bis 18 kN nach DIN 4226. Die vorteilhafte geringe Wärmeleitfähigkeit sichert eine hohe Wärmedämmung. Insofern wurde Blähglas bereits beim Errichten von Massivwänden eingesetzt und als Wärmedämmputz verwendet. Ebenso ist die Verwendung respektive die Zugabe von Blähglas in Asphalt bekannt. The starting material for expanded glass lightweight material is processed recycled glass. This is ground to glass powder, Shaped as raw granules and in a rotary kiln at around 750 sintered up to 900 ° C. This creates a viscous Layer of glass that surrounds the inflated granulate. By the granules are then given special control final size, e.g. B. divided into four Standard diameter groups from 0.2 to 0.5 mm, 0.5 to 1 mm, 1 to 2 mm and 2 to 4 mm. The expanded glass to be used for insulation purposes should have the most uniform possible fine-pored structure and have a largely closed surface. Of The advantage is the high dimensional stability down to one Temperature range of 750 ° C, resistance to frost and the non-flammability. With 190 to 300 g / l Bulk weight is extremely light and has an expanded glass high compressive strength in the range from 12 to 18 kN DIN 4226. The advantageous low thermal conductivity ensures high thermal insulation. In this respect expanded glass already used in the construction of solid walls and as Thermal insulation plaster used. The same is the use respectively the addition of expanded glass in asphalt is known.
Aus dem Vorgenannten ist es daher Aufgabe der Erfindung, an sich bekannte Rohre oder Rohrformstücke so weiterzubilden, daß diese verbesserte Wärmedämm- und/oder Stabilitäts- und Festigkeitseigenschaften besitzen, ohne daß die recht kostenintensive Ausgangsmaterialmenge, insbesondere bei Kunststoffen respektive die Wandstärke der Rohre erhöht werden muß. From the above, it is therefore an object of the invention known pipes or pipe fittings so to further develop that this improved thermal insulation and / or Have stability and strength properties without that the rather expensive amount of raw material, especially with plastics or the wall thickness the pipes must be increased.
Die Lösung der Aufgabe der Erfindung erfolgt mit einer Lehre gemäß Patentanspruch 1 sowie mit einem Verfahren nach Patentanspruch 4 oder 6. The object of the invention is achieved with a Teaching according to claim 1 and with a method according to claim 4 or 6.
Erfindungsgemäß wird den Ausgangsmaterialien eine Beimengung eines anorganischen geschlossenporigen Blähglases zugegeben oder es weisen die Rohe z. B. Kunststoffrohre oder -formstücke eine Blähglasbeschichtung, einen Blähglasüberzug oder eine Zwischenschicht aus Blähglas oder Blähglasgranalien auf. According to the invention, the starting materials Admixture of an inorganic closed-pore Expanded glass added or it has the raw z. B. Plastic pipes or fittings a expanded glass coating, one Expanded glass cover or an intermediate layer made of expanded glass or expanded glass granules.
Zur Erhöhung der chemischen Beständigkeit kann insbesondere die Rohrinnen- und/oder -außenwandung mit einer Beschichtung aus feinporigem Blähglas versehen sein. Insbesondere die Innenbeschichtung verbessert in überraschender Weise die Mitnahme von z. B. im Abwasser befindlichen fein- und feinstkörnigen Materialien aufgrund einer Wirbelbildung des flüssigen Mediums, welches innerhalb einer Kunststoffrohrleitung geführt wird, und zwar auch bei geringen Fließgeschwindigkeiten, wie es üblicherweise bei Abwasserrohrleitungen der Fall ist. Can increase chemical resistance in particular the inner and / or outer wall of the tube with a Coating made of fine-pored expanded glass. In particular, the inner coating improves in surprisingly, taking z. B. in wastewater fine and fine-grained materials due to a Vortex formation of the liquid medium inside a plastic pipe is performed, and indeed at low flow rates, as is usually the case is the case with sewage pipes.
Bei Kunststoffrohren kommt als Basismaterial PVC, PE, Polypropylen, schlagzähes Polystyrolpolymer ABS oder ASA, glasfaserverstärktes ungesättigtes Polyester UP-GF, Epoxydharz EP-GF oder Kunstharzbeton zum Einsatz. The basic material for plastic pipes is PVC, PE, Polypropylene, impact-resistant polystyrene polymer ABS or ASA, glass fiber reinforced unsaturated polyester UP-GF, Epoxy resin EP-GF or synthetic resin concrete is used.
Verfahrensseitig besteht die Möglichkeit, Blähglas bzw. Blähglasgranalien geeigneter Korngröße bzw. Durchmessergruppen bei extrudierbaren Kunststoffmaterialien dem Extruder zuzuführen, um auf diese Weise die gewünschte Beimengung zu erhalten. Eine Beimengung kann im selben Sinne auch bei Betonrohren oder Rohren aus keramischen oder dergleichen Materialien erfolgen. On the process side, there is the possibility of Expanded glass granules of suitable grain size or Diameter groups for extrudable plastic materials Feed extruder in order to achieve the desired one Obtain admixture. An admixture can be in the same This also applies to concrete pipes or pipes made of ceramic or similar materials.
Ebenso besteht die Möglichkeit, ausgangsseitig des Extruders ein Beblasen oder Bestreuen der extrudierten Oberfläche des jeweiligen Kunststoffmaterials mit Blähglaspartikeln vorzunehmen. There is also the possibility of the output side of the Extruders blowing or sprinkling the extruded Surface of the respective plastic material with To make expanded glass particles.
Bei der Herstellung von glasfaserverstärkten Kunststoffrohren oder derartigen Formstücken wird das Blähglas als Zuschlagsstoff in Ergänzung oder anstelle von Quarzsand in die Versteifungsschicht eingearbeitet bzw. eingebettet. In the manufacture of glass fiber reinforced The expanded glass is called plastic pipes or such fittings Additive in addition to or instead of quartz sand in the stiffening layer incorporated or embedded.
Das eingesetzte Blähglas, welches dem Ausgangsmaterial, insbesondere Kunststoffen beigemengt wird oder das eine Beschichtung darstellt, bildet aufgrund der vorteilhaften Wärmedämmeigenschaften einen Frostschutz, was insbesondere dann von Vorteil ist, wenn in den Rohrleitungen frostgefährdete Medien geführt werden. Ebenso führt die Wärmedämmung zu einer Verringerung unerwünschter Energieverluste bei Leitungssystemen, die beispielsweise der Warmwasserversorgung dienen. The expanded glass used, which is the starting material, especially plastics is added or one Represents coating forms due to the advantageous Thermal insulation properties antifreeze, which in particular is an advantage if in the pipes media at risk of frost. Likewise, the Thermal insulation to reduce unwanted Energy losses in line systems, for example serve the hot water supply.
Durch den Einbau von Blähglas bzw. Blähglasgranalien wird die Stabilität der Rohre verbessert und die Beständigkeit gegenüber Verkehrslasten erhöht. Aufgrund der Tatsache, daß die derartig gefertigten Rohre oder Kunststoff-Formstücke durch die Zugabe von eine geringe Masse aufweisendem Blähglas ebenfalls an Masse abnehmen, tritt eine geringere Bodenbelastung ein, was bei kritischen Verlegesituationen bzw. Untergründen von Vorteil ist. By installing expanded glass or expanded glass granules the stability of the pipes is improved and the resistance increased compared to traffic loads. Due to the fact, that the pipes or manufactured in this way Plastic fittings by adding a small mass having expanded glass also decrease in mass, one occurs lower floor load, which is critical Laying situations or substrates is an advantage.
Fertigungsseitig kann gemäß einem Ausführungsbeispiel der Erfindung bei der Herstellung von PVC- oder PE-Rohren beim Extrudieren des Polymerisats auf einer Schneckenpresse neben dem granulat- oder pulverförmigen Poylmerisat Blähglas zugeführt und auf diese Weise beigemengt werden. On the manufacturing side, according to an embodiment Invention in the manufacture of PVC or PE pipes Extrude the polymer on a screw press in addition to the granular or powdered polymer Expanded glass is added and added in this way.
Bei der Herstellung von GFK-Rohren wird in bekannter Weise von Polyesterharz als Bindemittel, textilen Glasfasergewirken als Bewehrung und Quarzsand als Zuschlagsstoff ausgegangen. Erfindungsgemäß wird Blähglas in die Versteifungsschicht mit eingearbeitet, so daß sich die stabilitäts- und festigkeitserhöhenden sowie verbesserten Wärmedämmeigenschaften ergeben. In the manufacture of GRP pipes in a known manner of polyester resin as a binder, textile Glass fiber fabrics as reinforcement and quartz sand as aggregate went out. According to the invention, expanded glass is placed in the Stiffening layer incorporated so that the stability and strength increasing and improved Thermal insulation properties result.

Fig. 3 eine Ausführungsform ähnlich Fig. 2 jedoch mit einer zur Innenseite des Rohres orientierten bzw. die Innenfläche abdeckenden Schicht aus Blähglas. Fig. 3 shows an embodiment similar to Fig. 2 but with the inside of the tube oriented and the inner surface of the covering layer of expanded glass.
Bei den anhand der Figuren beschriebenen Ausführungsbeispielen wird von einem glasfaserverstärktem Kunststoffrohr ausgegangen, ohne das jedoch diese Ausgangsmaterialwahl im Sinne der Erfindung beschränkend zu verstehen ist. In those described with reference to the figures Embodiments of a glass fiber reinforced Plastic tube, but without this The choice of starting material in the sense of the invention is to be understood as restrictive.
Die Lösung nach Fig. 1 geht von einer äußeren Schutzschicht 1 aus, die eine äußere Armierungsschicht 2 bedeckt. The solution 1 of FIG. Proceeds from an outer protective layer 1, an outer reinforcing layer 2 covered.
Eine Übergangsschicht 3 enthält Glasfasern, Polyesterharz und Sand. Die Versteifungsschicht 4 umfaßt ebenfalls Glasfasern, Polyesterharz und Sand sowie eine Zugabemenge von Blähglas zur Verbesserung der Wärmedämmung und damit der Frostsicherheit. A transition layer 3 contains glass fibers, polyester resin and sand. The stiffening layer 4 also comprises Glass fibers, polyester resin and sand as well as an added amount of expanded glass to improve thermal insulation and thus frost protection.
Die Übergangsschicht 5 entspricht in ihrem Aufbau im wesentlichen derjenigen oberhalb der Versteifungsschicht, was auch für die innere Armierungsschicht 6 gilt, die vergleichbare Eigenschaften wie die äußere Armierungsschicht 2 aufweist. The structure of the transition layer 5 corresponds to essentially those above the stiffening layer, which also applies to the inner reinforcement layer 6, the comparable properties as the outer Has reinforcement layer 2.
Die innere Armierungsschicht 6 ist von einer Sperrschicht 7 und diese wiederum von einer harzreichen inneren Deckschicht 8 umgeben. The inner reinforcement layer 6 is of a barrier layer 7 and this in turn from a resin-rich inner Surround layer 8.
Im Unterschied zur Ausführungsform nach Fig. 1 ist beim Ausführungsbeispiel nach Fig. 2 die äußere Schutzschicht 1 blähglashaltig oder aus Blähglas bestehend und die Versteifungsschicht 4 blähglasfrei. In contrast to the embodiment according to FIG. 1, in the exemplary embodiment according to FIG. 2, the outer protective layer 1 contains expanded glass or made of expanded glass and the stiffening layer 4 is free of expanded glass.
Die weitere Schichtenfolge entspricht derjenigen wie zur Fig. 1 beschrieben. The further layer sequence corresponds to that as described for FIG. 1.
Beim Ausführungsbeispiel illustriert mit Fig. 3 befindet sich innenseitig des Rohres eine Deckschicht 8, welche Blähglas enthält oder aus Blähglas besteht. Mit Ausnahme der äußeren Schutzschicht 1 ist ansonsten der Aufbau des Beispieles nach Fig. 3 ähnlich demjenigen wie in Fig. 2 gezeigt. In the exemplary embodiment illustrated with FIG. 3, there is a cover layer 8 on the inside of the tube which contains expanded glass or consists of expanded glass. With the exception of the outer protective layer 1, the structure of the example according to FIG. 3 is otherwise similar to that shown in FIG. 2.
Es liegt im Sinne der Erfindung, daß selbstverständlich auch Kombinationen der gezeigten Ausführungsbeispiele, z. B. ein Kunststoffrohr mit Versteifungsschicht 4, die Blähglas enthält sowie eine innere und/oder äußere blähglashaltige Schutzschicht realisiert werden können. It is within the spirit of the invention that of course also combinations of the exemplary embodiments shown, z. B. a plastic tube with stiffening layer 4, the Expanded glass contains as well as an inner and / or outer expanded glass-containing protective layer can be realized.
