Description
Die Erfindung betrifft ein Verfahren nach 197 19 684.5 zur Herstellung von Bauteilen, insbesondere von Bauplatten so wie von Gemischen, wobei neben Reststoffen aus fossil be triebenen Kraftwerken auch organische Stoffe zum Einsatz kommen.The invention relates to a method according to 197 19 684.5 Manufacture of components, especially building boards like this as from mixtures, whereby besides residues from fossil be powered plants also use organic substances come.
Bekannt ist es, aus dem bei der nassen Rauchgasentschwefe lung entstehenden Gips Wandplatten, sogenannte Gipskarton platten, herzustellen. Diese Platten sind aufgrund ihrer mangelnden Wasser- und Witterungsbeständigkeit ausschließ lich für den Innenausbau von Gebäuden einsetzbar.It is known from the wet flue gas desulfurizer The resulting gypsum wall panels, so-called plasterboard plates to manufacture. These plates are due to their exclude lack of water and weather resistance Can be used for the interior construction of buildings.
Weiterhin ist es bekannt, auf Gipsbasis nach dem Aufwickel verfahren Baurohplatten herzustellen, die neben dem in Form von CaSO4.1/2 H2O vorliegenden Gips auch Zement, Schlacken, Flugaschen, Kieselgur, Sand, mineralische und organische Fasern und Flockungshilfsmittel beinhalten (DE-OS 31 21 256).Furthermore, it is known to produce gypsum-based coils after the winding, which in addition to that in the form of CaSO 4 . 1/2 H 2 O present gypsum and cement, slag, fly ash, diatomaceous earth, sand, mineral and organic fibers and flocculants include (DE-OS 31 21 256).
Darüber hinaus gibt es leichte, nichttragende Trennwände aus nachwachsenden Rohstoffen, wie Flachs, Hanf, Stroh oder dgl. und Gips (DE-GM 297 14 805, 296 20 751). Alle diese Platten und Trennwände weisen den bereits bei den Gipskar tonplatten beschriebenen Mangel einer ausschließlichen Ver wendbarkeit für den Innenausbau auf. Des weiteren sind ihre Festigkeits- und Elastizitätswerte sehr niedrig, so daß die Einsatzgebiete auch dort stark eingeschränkt sind.There are also lightweight, non-load-bearing partitions from renewable raw materials, such as flax, hemp, straw or Like. and gypsum (DE-GM 297 14 805, 296 20 751). All these Panels and partitions already show this in the Gipskar clay plates described lack of an exclusive Ver versatility for interior work. Furthermore, theirs Strength and elasticity values very low, so that the Areas of application are also severely restricted there.
Als Bindemittel für Bauplatten sind Zement, α- und β- Halbhydrat aus Natur-Gips bzw. REA-Gips bekannt.Cement, α- and β- are used as binders for building boards. Hemihydrate from natural gypsum or REA gypsum known.
Zur Immobilisierung von Schadstoffen ist ein Verfahren zur Herstellung eines Bindemittels bekannt, wobei die Ausgangs stoffe für die Speicherkomponenten aus Verbrennungsrück ständen, wasserhaltigen Substanzen und CaO gemischt und ei ner speziellen thermischen Behandlung unterzogen werden (DE 197 19 684). A method for the immobilization of pollutants is Manufacture of a binder known, the starting substances for the storage components from combustion waste stands, water-containing substances and CaO mixed and egg undergo a special thermal treatment (DE 197 19 684).
Ein baustofftechnischer Einsatz dieses Produkts ist nicht näher beschrieben.This product is not used for building materials described in more detail.
Weiterhin ist ein thermisches Verfahren bekannt, bei wel chem Schaumglasprodukte mit granulatartigen Eigenschaften aus Flugstaub oder Flugasche sowie Alkalisilikaten herge stellt werden, wobei Flugstaub und Alkalisilikat- oder Al kalihydroxidlösungen sowie Wasser vermischt, das Gemisch durch mehrstündiges Erwärmen auf bis zu 100°C zum Erhärten gebracht, die abgekühlte Masse zerkleinert, eine Fraktion von < 1,6 und < 3,15 mm abgesiebt und das erhaltene Produkt durch eine erneute Wärmebehandlung bei 150-300°C aufge bläht (25-35 Minuten) wird (DE-OS 31 36 888). Das ent sprechende Produkt ist für Isolierzwecke einsetzbar. Der Herstellungsprozeß verdeutlicht, daß das auf eine derart aufwendigen Art und Weise gefertigte Granulat nur unter Verwendung großer Energie- und Technologieaufwendungen pro duzierbar ist, was sich zweifellos auf seinen Preis auswir ken muß.Furthermore, a thermal method is known in which chem foam glass products with granular properties from fly dust or fly ash and alkali silicates are posed, fly dust and alkali silicate or Al Potash solutions and water mixed, the mixture by heating up to 100 ° C for several hours to harden brought, the cooled mass crushed, a fraction sieved from <1.6 and <3.15 mm and the product obtained by renewed heat treatment at 150-300 ° C puffs (25-35 minutes) (DE-OS 31 36 888). That ent speaking product can be used for insulation purposes. The Manufacturing process shows that this is the case elaborate way manufactured granules only under Use of large energy and technology expenses per is doable, which undoubtedly affects its price must.
Der Erfindung liegt die Aufgabe zugrunde, leichte und sta bile Bauteile und/oder Gemische herzustellen, die vielsei tig verwendbar sind, hauptsächlich aus Reststoffen bestehen und einfach sowie kostengünstig produzierbar sind.The invention is based, light and sta to manufacture bile components and / or mixtures that are versatile are usable, mainly consist of residues and are easy and inexpensive to produce.
Dies wird dadurch erreicht, daß erfindungsgemäß als Binde mittel thermisch behandeltes Gemisch aus Verbrennungsrück ständen, wasserhaltigen Substanzen und CaO zum Einsatz kommt, wobei dieses mit an sich bekannten Schaumbildnern und Wasser vermischt, ggf. anschließend in Formen verpreßt und zur Aushärtung gebracht wird.This is achieved in that according to the invention as a bandage medium thermally treated mixture from combustion back stands, water-containing substances and CaO comes, this with known foaming agents and water mixed, if necessary subsequently pressed into molds and is hardened.
Als Verbrennungsrückstände kommen Braunkohlen-, Steinkoh len-, Wirbelschichtfilteraschen in Betracht. Die wasserhal tigen Substanzen können Wasser bzw. kristallwasserhaltige Flüssigkeiten bzw. Stoffe und teilentwässertes Gips- Dihydrat sein. Lignite and hard coal come as combustion residues len-, fluidized bed filter ash into consideration. The water term substances can be water or water containing crystal water Liquids or substances and partially dewatered gypsum Be dihydrate.
Als Schaumbildner bzw. Treibmittel können alle chemischen Stoffe und Verbindungen, die durch eine chemische und/oder physikalische Reaktion einen Bläh- oder Schäumungsvorgang auslösen, verwendet werden.All chemical can be used as foaming agents or blowing agents Substances and compounds created by a chemical and / or physical reaction a swelling or foaming process trigger, be used.
Der Schaumbildner wird in einer Menge von 0,3-3 M-%, bezo gen auf das Gesamtgemisch, verwendet. Der Anteil des Binde mittelleims beträgt zwischen 5-60 M-%, je nach Verwen dungszweck des Produkts, wobei eine stark wärmedämmende Verwendung bei untergeordneter Tragfähigkeit im unteren Be reich und eine weniger wärmedämmende Verwendung bei erhöh ter Tragfähigkeit im oberen Bereich angesiedelt ist. Der Schaumbildner wird dabei zuerst dem Wasser oder gleichzei tig mit diesem dem Mischer zugegeben. Zur Erzeugung der notwendigen Luftporenmenge ist eine erhöhte Mischzeit (min destens 120 Sekunden) erforderlich.The foaming agent is used in an amount of 0.3-3% by mass gene on the total mixture used. The proportion of the bandage middle glue is between 5-60 M%, depending on the use purpose of the product, being a highly heat-insulating Use with lower load capacity in the lower part rich and a less heat-insulating use when increasing load capacity is located in the upper area. The Foaming agent is first the water or at the same time with this added to the mixer. To generate the the required amount of air pores is an increased mixing time (min at least 120 seconds) is required.
Überraschenderweise hat sich herausgestellt, daß ein in der beschriebenen Art und Weise hergestelltes Gemisch ohne spe zielle Luftzufuhr oder besondere Behandlung unter Lufter härtung ein Produkt ergibt, aus welchem Betone, Platten, Steine etc. herstellbar sind, die teilweise gute bis sehr gute Wärmedämmwerte bei ausreichenden Trageigenschaften er zielen.Surprisingly, it has been found that one in the described manner produced mixture without spe air supply or special treatment under ventilation curing results in a product from which concretes, slabs, Stones etc. can be produced, some of which are good to very good good thermal insulation values with sufficient wearing properties aim.
