Abstract
Die vorliegende Erfindung betrifft die Verwendung von Industrie- und Verbrennungsaschen die als Dämmstoff für die energetische Sanierung und beim Neubau zum Einsatz kommen. In der vorliegenden Erfindung werden herkömmliche Schütt- und Einblasdämmung durch Asche ergänzt oder substituiert. Die Asche kommt ausschliesslich als Hohlraumdämmung für Böden, Wände, Decken, Schächte, Hohlziegel oder Hohlplatten zum Einsatz. Es kommen nur Aschen zum Einsatz, bei der die für eine baustoffliche Verwertung relevanten Grenzwerte der Verordnung über die Vermeidung und die Entsorgung von Abfällen (VVEA) eingehalten werden - und/oder aber Deponieprodukte, Trockenschlämme und artverwandte Produkte, die Papierasche als Trocknungs- und Verfestigungmittel enthalten.The present invention relates to the use of industrial and combustion ashes which are used as insulation material for energy-related renovations and in new buildings. In the present invention, conventional fill and blown insulation are supplemented or substituted by ash. The ash is used exclusively as cavity insulation for floors, walls, ceilings, shafts, hollow bricks or hollow panels. Only ashes are used that comply with the relevant limit values of the Ordinance on the Prevention and Disposal of Waste (VVEA) for building material recycling - and/or landfill products, dry sludge and related products, paper ash as a drying and solidifying agent contain.
Description
Gegenstand und/oder technisches GebietSubject and/or technical area
[0001] Gegenstand der Erfindung ist die Verwendung von Industrie- und Verbrennungsaschen die als Dämmstoff für die energetische Sanierung und beim Neubau zum Einsatz kommen. The subject of the invention is the use of industrial and combustion ashes, which are used as insulating material for energy-related renovations and in new buildings.
Stand der TechnikState of the art
[0002] Stoffe wie Industrie- und Verbrennungsaschen werden bislang überwiegend als Abfall zur Verwertung an vornehmlich die Bau- und Zementindustrie abgegeben - oder aber deponiert. In der Schweiz kostet die Entsorgung der Altpapierflugasche derzeit rund 50 Franken pro Tonne. Es gibt derzeit aber auch eine Vielzahl von Forschungsprojekten mit Patenten und/oder Rezepturen, wobei man für Dämmplatten oder Dämmmatten zertifizierte Industrieabfälle aus verschiedenen Industriebereichen wie der Kohle-, Papier- oder Metallindustrie einsetzt. Also auch Industrie- und Verbrennungsaschen. [0002] Substances such as industrial and incineration ashes have so far been predominantly given as waste for recycling to the construction and cement industries - or else landfilled. In Switzerland, the disposal of waste paper fly ash currently costs around 50 francs per ton. However, there are currently a number of research projects with patents and/or recipes using certified industrial waste from various industrial sectors such as the coal, paper or metal industries for insulation boards or insulation mats. So also industrial and incineration ash.
NachteilDisadvantage
[0003] Verbrennungsasche wie zum Beispiel Papierasche weist zwar eine dem Zement ähnliche chemische Zusammensetzung auf, wobei jedoch der Mineralphasenbestand deutlich abweicht und weniger reaktiv ist. Daher ist ein kostspieliger Prozess zur Aktivierung der Papierasche vor der Nutzung als Bindemittel notwendig, zum Beispiel eine sogenannte hydrothermale Calcinierung. Um vorwiegend aus Industrie- und Verbrennungsaschen einsatzfähige Dämmplatten oder Dämmmatten zu produzieren, sind gemäss Stand der Technik aufwändige Guss- oder Schäumungsverfahren nötig. Dabei kommen zum Teil mehrere Zuschlagstoffe, auch Abfallstoffe, zum Einsatz - dies alles kann nur im Umfeld einer kostspieligen industriellen Produktion wirtschaftlich hergestellt werden. Although combustion ash such as paper ash has a similar chemical composition to cement, the mineral phase composition differs significantly and is less reactive. Therefore, a costly process is necessary to activate the paper ash before using it as a binder, for example a so-called hydrothermal calcination. In order to produce usable insulation boards or insulation mats primarily from industrial and incineration ashes, complex casting or foaming processes are necessary according to the current state of the art. In some cases, several additives, including waste materials, are used - all of this can only be produced economically in the context of costly industrial production.
AufgabeTask
[0004] Die Aufgabe der Erfindung besteht darin, dass Industrie- und Verbrennungsaschen als Wärme- oder Schalldämmmaterialien eingesetzt werden können, ohne dass ein hoher Energie- oder Produktionsbedarf (z.B. industrielle Dämmplattenproduktion) die Verwendung unwirtschaftlich macht. Aufgabe ist es zudem, dass aus den Industrie- und Verbrennungsaschen nicht Dämmstoffe in From von Platten oder Matten hergestellt werden. The object of the invention is that industrial and combustion ashes can be used as heat or sound insulation materials without high energy or production requirements (e.g. industrial insulation board production) making their use uneconomical. It is also important to ensure that the industrial and incineration ashes are not used to produce insulation materials in the form of panels or mats.
LösungSolution
[0005] Diese Aufgabe wird durch verschiedenen Verfahrensansätze mit den Merkmalen des Anspruchs 1 bis 5 gelöst. This problem is solved by various method approaches with the features of claims 1 to 5.
VorteileAdvantages
[0006] Mit der Substitution von bewährten Schütt- oder Einblasdämmstoffen durch ohnehin anfallende Abfallstoffe welche ansonsten mehrheitlich deponiert werden müssen, ergeben sich ökologische Vorteile wie unter anderem die Einsparung von Deponieraum und es werden Primärrohstoffreserven geschont. Da die Asche im geschützten Hohlraum nicht als Bindemittel aktiviert werden muss, kann auf weitere Bindemittel, Zuschlagstoffe oder eine Produktionsanlage verzichtet werden. [0006] By substituting tried-and-tested bulk or blown-in insulation materials with waste materials that are produced anyway, most of which otherwise have to be landfilled, there are ecological advantages such as, among other things, the saving of landfill space and primary raw material reserves are conserved. Since the ash in the protected cavity does not have to be activated as a binder, there is no need for additional binders, additives or a production system.
