Die Erfindung betrifft die gefahrlose Beseitigung mineralischer Fasern und Faserstoffe, insbesondere von Asbest und Asbestprodukten, und deren Umwandlung in einen Wertstoff, insbesondere in Zement (Portlandzement, Zementklinker).The invention relates to the safe removal of mineral fibers and fibrous materials, especially of asbestos and asbestos products, and their conversion in a valuable substance, especially in cement (Portland cement, cement clinker).
Die Zusammensetzung von Portlandzementen und Zementklinkern ist entsprechend DIN 1164 festgelegt. Haupt- und Spurenelementzusammensetzung mineralischer Fasern und Faserstoffe und von Asbest und Asbestprodukte kann durch Analyse leicht festgelegt werden.The composition of Portland cements and cement clinkers is corresponding DIN 1164 specified. Main and trace element composition of mineral Fibers and fibrous materials and from asbestos and asbestos products can easily determined by analysis.
So bestehen z. B. Serpentinasbeste (Krokydolith, Blauasbest aus wasserhaltigen Mg-Silicaten und Amphibolasbeste (Chrysotil, Weißasbeste) - vereinfacht - aus Ca-, Na-, Fe-, Mg-Silikaten. Glasfasern und Gesteinsfasern bestehen zum großen Teil aus verschiedenen zuammengesetzten Silikatgläsern. Da Zement bzw. Zementklinker aus Mg-, Fe-, Na-haltigen Calcium-Aluminiumsilikaten besteht, sind dessen chemische Bestandteile in den Mineralfasern, zumindest teilweise, schon enthalten.So z. B. Serpentinasbeste (crocidolite, blue asbestos from water-containing Mg silicates and best amphibole (chrysotile, white asbestos) - simplified - from Ca, Na, Fe, Mg silicates. Glass fibers and rock fibers exist for large part of different composite silicate glasses. Because cement or cement clinker consists of calcium, aluminum, magnesium, Fe and Na silicates, are its chemical components in the mineral fibers, at least partially, already included.
Durch geeignetes Mischen der feingemahlenen Faserstoffe mit Rohstoffen, wie sie bei der Zementproduktion verwendet werden, (das sind z. B. Kalkstein, Kreise, Tone und Kalksteinmerkel, Gipsstein oder Anhydrid, Hüttensand oder Traß) kann die Gesamtzusammensetzung des Materials so eingestellt werden, daß es der Zusammensetzung von Zementen nach DIN, oder auch anderen zementähnlichen Wertstoffen entspricht.By appropriately mixing the finely ground fibers with raw materials such as they are used in cement production (e.g. limestone, Circles, clays and limestone markers, gypsum stone or anhydride, slag sand or Trass) the overall composition of the material can be adjusted that it is the composition of cements according to DIN, or other corresponds to cement-like materials.
Die Reaktion lautet dann:
Mineralfasern + Zuschläge - (bei 1250-1450°C) → Portlandzement + WasserThe reaction is then:
Mineral fibers + aggregates - (at 1250-1450 ° C) → Portland cement + water
Die Berechnung der gewünschten chemischen Zusammensetzung kann mit einem Rechnerprogramm erfolgen, das zusätzlich den Kalkstandard (KSt) den Tonerdemodul TM, den Silicatmodul (SM) und den Kalksättigungsgrad (KSG) einbezieht, um die Toleranzen der DIN-Norm für die Portlandzementzusammensetzung einzuhalten.The chemical composition can be calculated using a Computer program take place that additionally the lime standard (KSt) Alumina module TM, the silicate module (SM) and the degree of lime saturation (KSG) includes the tolerances of the DIN standard for Portland cement composition to adhere to.
In zahlreichen Versuchen wurde dies an mehreren mineralischen Faserstoffen, insbesondere Asbestprodukten im Labormaßstab erprobt. (siehe Diplomarbeit unter meiner Anleitung an der Universität zu Köln, Köln 1992).In numerous experiments, this was done on several mineral fibers, especially tested asbestos products on a laboratory scale. (see diploma thesis under my guidance at the University of Cologne, Cologne 1992).
Die Mischung wird gemahlen, homogenisiert und anschließend in einen Drehrohrofen bei Temperaturen zwischen 1250°C und 1450°C gebrannt, wie mit dem Rasterelektronenmikroskop und röntgendiffraktometrisch nachgewiesen werden konnte. Das gebrannte Produkt besteht ausschließlich aus Zementphasen (Alit, Belit, C₃A, C₄AF und Matrix).The mixture is ground, homogenized and then in a rotary kiln fired at temperatures between 1250 ° C and 1450 ° C, as with using a scanning electron microscope and X-ray diffraction could be. The burned product consists exclusively of Cement phases (alite, belite, C₃A, C₄AF and matrix).
Die Versuche haben ergeben, daß nach einer Brennzeit von ca. 30 Min. bei Temperaturen von größer 1250°C mit dem Rasterelektronenmikroskop keine Fasern mehr nachweisbar sind. Dies ist auch aufgrund der Phasengleichgewichte in diesen Systemen anzunehmen, da sowohl Asbeste als auch Glasfasern und anderes Fasermaterial bei diesem Temperaturen nicht mehr thermodynamisch stabil sind, deshalb zersetzt werden oder schmelzen.The tests have shown that after a burning time of approx. 30 min Temperatures of more than 1250 ° C with the scanning electron microscope none Fibers are more detectable. This is also due to the phase equilibria to be assumed in these systems since both asbestos and glass fibers and other fiber material no longer at this temperature are thermodynamically stable, therefore they decompose or melt.
Untersuchungen der pohysikalischen Eigenschaften der erhaltenen Zemente haben gezeigt, daß diese innerhalb der für Zemente geforderten DIN-Werte liegen.Investigation of the physical properties of the cements obtained have shown that these are within the DIN values required for cements.
Die erhaltenen Zemente können gemahlen und als normale Zemente (z. B. PZ 35, PZ45) in den Handel gebracht werden.The cements obtained can be ground and used as normal cements (e.g. PZ 35, PZ45).
