Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Mineralwollprodukts, insbesondere einer Mineralwollplatte nach dem Oberbegriff des Anspruchs 1 und betrifft ferner ein Mineralwollprodukt, insbesondere eine Mineralwollplatte gemäß dem Oberbegriff des Patentanspruches 6. Insbesondere bezieht sich die Erfindung auf Glaswolleprodukte und deren Herstellung.The The invention relates to a process for producing a mineral wool product, in particular a mineral wool plate according to the preamble of the claim 1 and further relates to a mineral wool product, in particular a Mineral wool plate according to the preamble of claim 6. In particular, the invention relates on glass wool products and their manufacture.
Mineralwollprodukte, insbesondere solche aus Glaswolle oder Steinwolle, werden überwiegend zu Wärmedämmzwecken verwendet und zwar insbesondere für die Wärmedämmung von Gebäuden im Bereich von Dächern, Wänden und Decken. Dabei werden die Mineralwollbahnen oder Mineralwollplatten zwischen Sparren oder Balken gelegt und ggf. mittels vorstehender Ränder von Alukaschierungen an den Balken bzw. Sparren durch Tackern befestigt oder aber mit Klemmsitz zwischen den Sparren und Balken eingepreßt, womit dann eine mechanische Befestigung entfallen kann.Mineral wool products, especially those made of glass wool or rock wool, become predominantly thermal insulation purposes used and in particular for the thermal insulation of buildings in the area of roofs, walls and blankets. This will be the mineral wool or mineral wool plates placed between rafters or beams and possibly by means of the above margins of aluminum laminates attached to the beams or rafters by tacking or but pressed with a press fit between the rafters and beams, which then a mechanical attachment can be omitted.
Eine Problematik bei der Wärmedämmung von Dächern und dergleichen ergibt sich allerdings dadurch, dass sehr häufig der Abstand zwischen den Sparren oder Balken nicht gleich ist, sondern innerhalb eines Gebäudes durchaus divergiert, so dass es erforderlich ist, die zwischen den Sparren oder Balken einzubringende Wärmedämmplatte oder Wärmedämmbahn auf diese divergierenden Sparren- bzw. Balkenabstände auszulegen bzw. herzurichten.A Problems with the thermal insulation of roofs and the like, however, results from the fact that very often the Distance between rafters or beams is not the same, but inside a building quite divergent, so it is necessary that between the Rafters or beams to be introduced thermal insulation board or insulation board on interpret or prepare these divergent rafter or beam distances.
Hierzu ist es bekannt, dass Wärmedämmbahnen, die üblicherweise in Rollenform angeliefert werden, auf bestimmte, fein abgestufte Nennbreiten hergestellt und bereitgehalten werden, so dass je nach Abstandsverhältnis zwischen den Sparren eine Bahn mit einer gewünschten Nennbreite verwendet wird. Dabei ergeben sich aber entsprechende Schnittverluste. Überdies führt die notwendige Bereitstellung von Mineralwollbahnen mit abgestuften Nennbreiten zu einer entsprechend großen Vorratshaltung der einzelnen Produkte, was wiederum sehr nachteilhaft ist.For this it is known that thermal insulation webs, the usual be delivered in roll form, on certain, finely graded Nominal widths are made and kept available, so depending on distance ratio between the rafters a web with a desired nominal width is used. But this results in corresponding cutting losses. moreover leads the necessary provision of mineral wool webs with graduated nominal widths to a correspondingly large Inventory of the individual products, which in turn is very disadvantageous is.
Nach einer geschickten Lösung werden sogenannte Klemmfilze verwendet, d. h. Mineralwollbahnen mit höherer Biegesteifigkeit, die im Herstellerwerk zur Raumersparnis unter Druck aufgerollt werden und die auf mindestens einer der großen Oberflächen mit Quermarkierungen in Streifenform und dgl. Versehen sind, die als Schnitthilfslinien dienen. Längs dieser Quermarkierungen oder parallel zu diesen erfolgt ein Ablängen entsprechender Mineralwollabschnitte von der Bahn, wobei die Länge der Abschnitte jeweils entsprechend dem lichten Abstand zwischen den Sparren plus einem geringen Übermaß bemessen sind. Dadurch erfolgt eine individuelle Anpassung an die Sparren und die Bahn kann vollständig ausgenutzt werden. Infolge der höheren Biegesteifigkeit ergibt sich ferner, dass nach Ausrollen der Mineralwollbahn die abgelängten Mineralwollabschnitte sozusagen als Platte vorliegen, wodurch der Slogan geprägt wurde „die Platte von der Rolle", und dass ferner durch den Klemmsitz der mit Übermaß zwischen den Sparren eingebrachten Mineralwollabschnitte eine lückenfreie Wärmedämmung auch an den Stoßstellen mit den Sparren oder Balken gewährleistet wird.To a clever solution So-called pinch felts are used, d. H. Mineral wool paths with higher Flexural rigidity, which in the manufacturing plant to space savings under pressure be rolled up and on at least one of the large surfaces with Cross marks in strip form and the like. Are provided, which as Serve cutting guides. Along These cross marks or parallel to these is a cutting to length appropriate Mineral wool sections from the web, with the length of the sections respectively according to the clear distance between the rafters plus one measure small excess are. This results in an individual adaptation to the rafters and the web can be complete be exploited. As a result of the higher Flexural rigidity also results that after rolling out of the mineral wool web the cut to length Mineral wool sections so to speak as a plate, whereby the Slogan shaped was the Plate of the roll ", and that further introduced by the interference fit of the oversized between the rafters Mineral wool sections a gap-free Thermal insulation too at the joints guaranteed with the rafters or beams becomes.
WO 97/36034 beschreibt ein Mineralwollprodukt aus Schichten mit unterschiedlichen Dichten, die miteinander verbunden sind.WHERE 97/36034 describes a mineral wool product of layers with different Densities that are interconnected.
Gleichwohl ergibt sich ein Bedürfnis nach weiteren alternativen Mineralwollprodukten zur Wärmedämmung zwischen Sparren bzw. Balken. Aufgabe der Erfindung ist es somit, ein verschnittfreies Mineralwollprodukt zu schaffen, welches ein ausgewogenes Verhältnis zwischen Flexibilität und Biegesteifigkeit verfügt, wobei ein Verfahren geschaffen werden soll, mit dem insbesondere in geeigneter und einfacher Weise dieses Verhältnis zwischen Flexibilität und Steifigkeit eingestellt werden kann. Die hierdurch geschaffene Mineralwollplatte soll im Handling einfach sein, eine vielfältige Anwendung durch die Möglichkeit eines quasi inherent vorhandenen Toleranzausgleichs gewährleisten und sich ferner insbesondere für die Anbringung zwischen Balken und Sparren bei der Gebäudedämmung eignen. Insbeson dere soll ein fester und aus Gründen der einwandfreien Dämmung wärmebrückenfreier Sitz mit inniger Anlage der Mineralwollplatte an den benachbarten Sparren oder Balken gewährleistet werden.nevertheless there is a need for further alternative mineral wool products for thermal insulation between Rafters or beams. The object of the invention is therefore a waste-free Mineral wool product to create a balance between flexibility and flexural rigidity, wherein a method is to be created, with the particular in a suitable and simple way this relationship between flexibility and rigidity can be adjusted. The mineral wool plate created thereby should be easy to handle, a versatile application by the possibility ensure a virtually inherent tolerance compensation and furthermore in particular for the attachment between beams and rafters in the building insulation are suitable. In particular, a solid and for the sake of sound insulation heat bridge free Seat with intimate attachment of the mineral wool plate to the adjacent Rafters or beams guaranteed become.
Diese Aufgabe wird erfindungsgemäß für das Verfahren durch die Merkmale des Anspruches 1 gelöst, hingegen erfindungsgemäß für das Mineralwollprodukt durch die Merkmale des Anspruches 6.These Task is according to the invention for the process solved by the features of claim 1, however, according to the invention for the mineral wool product by the features of claim 6.
Zweckmäßige Weiterbildungen sowohl des Verfahrens wie auch des Mineralwollprodukts ergeben sich aus den entsprechenden abhängigen Unteransprüchen.Appropriate further education Both the process as well as the mineral wool product arise from the corresponding dependent Dependent claims.
Nach Maßgabe der Erfindung zeichnet sich ein Verfahren zur Herstellung der erfindungsgemäßen Mineralwollprodukts dadurch aus, dass die Bahn oder Platte vor der Aushärtung in mindestens einem Abschnitt, der eine der beiden großen Hauptflächen der Platte oder Bahn begrenzt, einem sogenannten Crimping-Prozess, einer Art Stauchen in Längsrichtung unterzogen wird. Durch diesen Prozess ergibt sich ein Auf und Ab der Fasern in diesem Abschnitt, wohingegen die Fasern im benachbarten darüber liegenden Abschnitt im wesentlichen ihre ursprüngliche Orientierung beibehalten, d. h. die Faserausrichtung ist in diesem Abschnitt im wesentlichen parallel zu den beiden großen Hauptflächen. Durch diesen Crimping-Vorgang ergibt sich eine erhöhte Dichte in dem durch das Crimping bearbeiteten Abschnitt und es ergibt sich in Längsrichtung gesehen eine erhöhte Flexibilität in der Form einer Zusammendrückbarkeit (in Art einer Knautschzone), wohingegen die Eigenschaften der angrenzenden nicht durch Crimping bearbeitete Schicht bzw. Abschnitt nicht verändert sondern im wesentlichen beibehalten werden. Dadurch ergibt sich ein ausgewogenes Verhältnis zwischen Flexibilität und Steifigkeit, wobei dies noch begünstigt wird durch die erhöhte Dichte infolge des Crimping-Vorgangs.According to the invention, a method for producing the mineral wool product according to the invention is characterized in that the web or plate before curing in at least one section that limits one of the two major major surfaces of the plate or web, a so-called crimping process, a type of compression in the longitudinal direction is subjected. This process results in an up and down of the fibers in this section, whereas the fibers in the adjacent overlying section retain substantially their original orientation, ie the fiber orientation in this section is substantially parallel to the two major major surfaces. This crimping process results in an increased density in the crimping machined portion and provides increased flexibility in the longitudinal direction in the form of compressibility (in the crumple type), whereas the properties of the adjacent non-crimping layer or crimping zone Section not changed but essentially retained. This results in a balance between flexibility and stiffness, which is still favored by the increased density due to the crimping process.
Hierbei ist es im Rahmen der Erfindung zweckmäßig, dass nur ein Abschnitt dem Crimping-Prozess unterworfen wird und zwar insbesondere einer der beiden die großen Hauptfläche begrenzenden Abschnitte, der sich über die Länge der Bahn bzw. Platte erstreckt.in this connection It is expedient in the context of the invention that only a section subjected to the crimping process, in particular one the two are the big ones main area delimiting sections that extend the length of the track or panel.
Zweckmäßigerweise erfolgt der Crimping-Vorgang durch hintereinander geschaltete Förderer, die mit unterschiedlicher und zwar abgestuft geringer werdenden Fördergeschwindigkeit betrieben werden. Dadurch wird an den Stoßstellen der aneinander angrenzenden Förderer, die mit unterschiedlicher Geschwindigkeit betrieben werden, eine Art Kräuseln der Fasern bewerkstelligt, da mehr Mineralwolle zugefördert als abgefördert wird. Hierbei ist es zweckmäßig, dass die Förderer unterhalb der Mineralwollbahn angeordnet werden, weil hier in sehr kontrollierter Weise der untere Abschnitt der Mineralwollbahn durch das Eigengewicht dem gewünschten Crimping-Vorgang ausgesetzt werden kann. Im Prinzip genügen zwei Förderer mit unterschiedlicher Geschwindigkeit, um den gewünschten Crimping-Vorgang zu ermöglichen, jedoch werden zweckmäßigerweise vier Förderer vorgesehen, wobei bei Bedarf jedoch auch mehr als vier Förderer vorgesehen sein können. Besonders zweckmäßig werden Endlosförderbänder als Förderer verwendet. Bei Bedarf kann auch oberhalb der Fördereinheit aus den Förderern mit abgestuften Fördergeschwindigkeiten ein Förderer quasi als Gegenhalter oder auch mehrere Förderer verwendet werden, wobei dann der Crimping-Prozess durch die gegen die oben an der Mineralwollbahn anliegenden Förderer vorgenommen werden kann.Conveniently, the crimping process is carried out by conveyors connected in series, those with different and graduated gradually decreasing conveyor speed operate. This will be at the joints of the adjacent conveyors, which are operated at different speeds, a kind frizz the fibers accomplished, as more mineral wool supplied as carried away becomes. It is expedient that the sponsors be arranged below the mineral wool track, because here in very controlled Make the lower section of the mineral wool web by its own weight the desired crimping process can be suspended. In principle, two conveyors with different ones are sufficient Speed to the desired Crimping process to enable however, it will be convenient four sponsors provided, however, provided if necessary, more than four conveyor could be. Be particularly useful Endless conveyor belts as promoter used. If necessary, above the conveyor unit from the conveyors with graded conveying speeds a promoter quasi as a counter-holder or even several conveyors are used, whereby then the crimping process through against the top of the mineral wool web adjoining conveyor can be made.
Ein gleichmäßiges Kräuselbild ergibt sich bei gleichmäßiger Abstufung der Fördergeschwindigkeiten. Der Crimping-Vorgang kann um so mehr intensiviert werden, je stärker die Geschwindigkeitssprünge sind.One even rippled picture results in even gradation the conveyor speeds. The crimping process can be intensified the more the stronger Speed jumps are.
Zweckmäßigerweise ist die Fördergeschwindigkeit des schnellsten Förderers der abgestuften Förderer um etwa 20% größer als die des Aushärteofens, wobei die Abstufungen zwischen den 4 Förderern jeweils bei 4% liegen. Auch die Länge des Obertrums der Förderer des abgestuften Fördersystems kann als Einflussparameter für den Crimping-Vorgang hergezogen werden. Je kürzer die Länge des Obertrums dieser Förderer ist, je intensiver wird der Crimping-Vorgang und die Crimping-Struktur. Auch die Dicke des Abschnitts mit den gestauchten Fasern kann durch geeignete Wahl der Länge der Förderbänder bestimmt werden, aber auch die Abstände zwischen den Förderern.Conveniently, is the conveying speed the fastest conveyor the graduated conveyor about 20% larger than the curing oven, the gradations between the 4 conveyors are each 4%. Also the length the upper strand of the sponsors the graded conveyor system can as an influence parameter for the crimping process be pulled. The shorter the length of the upper run of these conveyors, The more intense the crimping process and the crimping structure. The thickness of the section with the compressed fibers can by suitable choice of length the conveyor belts determined but also the distances between the sponsors.
Das erfindungsgemäße Mineralwollprodukt, insbesondere die Mineralwollplatte zeichnet sich dadurch aus, dass mindestens zwei Abschnitte mit unterschiedlicher Faserorientierung gegeben sind, wobei in vorteilhafter Weise einer dieser Abschnitte eine der Hauptflächen der Platte begrenzt und dieser Abschnitt mit durch einen Crimping-Prozess hervorgerufener Faserstruktur ausgebildet ist. Zweckmäßigerweise weist das Mineralwollprodukt nur zwei Abschnitte mit unterschiedlicher Faserorientierung auf. Der durch den Crimping-Prozess beeinflusste Abschnitt kann hierbei bis zu 90% der Produktdicke betragen, er liegt jedoch insbesondere in einem Dickenbereich von bis zu 1/3 der Produktdicke. Dadurch ergibt sich eine gewünschte feine Abstimmung zwischen der Flexibilität und gewünschter Biegesteifigkeit.The Mineral wool product according to the invention, in particular The mineral wool plate is characterized by the fact that at least given two sections with different fiber orientation are, wherein advantageously one of these sections one of main areas limited to the plate and this section with through a crimping process formed fiber structure is formed. Conveniently, the mineral wool product has only two sections with different Fiber orientation on. The one influenced by the crimping process Section can be up to 90% of the product thickness, he however, lies in particular in a thickness range of up to 1/3 the product thickness. This results in a desired fine tuning between the flexibility and desired Flexural strength.

Insgesamt ist mit dem erfindungsgemäßen Mineralwolleprodukt eine verschnittfreie Dämmung zwischen Sparren bzw. Balken möglich, da dieses Produkt durch den partiellen Crimping-Vorgang 1,5–5% des lichten Maßes zwischen den Sparren bzw. Balken problemlos ausgleichen kann, d. h. eine entsprechende Knautschzone besitzt. Schließlich wird der geringe Verlust des sogenannten λ-Wertes – bedingt durch die Faserumorientierung des Crimping-Vorgangs – dadurch ausgeglichen, dass die die Eingangsrohdichte etwa um 0,5 kg/m3 insgesamt erhöht wird, welche zwischen 8–30 kg/m3, insbesondere 15–20 kg/m3 liegt.Overall, a waste-free insulation between rafters or beams is possible with the mineral wool product according to the invention, since this product can easily compensate for 1.5-5% of the clear dimension between the rafters or beams by the partial crimping process, ie has a corresponding crumple zone. Finally, the small loss of the so-called λ-value - due to the fiber reorientation of the crimping process - is compensated by the fact that the total input density is increased by about 0.5 kg / m 3 , which is between 8-30 kg / m 3 , especially 15-20 kg / m 3 .
