Abstract

Asbestos materials are treated to avoid health risks by simultaneous thermal and mehcanical treatment of chrysotile and crocidolite to effect destruction and opt. sintering of the fibrous structure. USE - The treated products can be used as non-hazardous components of building materials or as base material for recovery of values.

Description

Es ist bekannt, daß Asbestmaterialien in Faserform beim Einatmen in die Lunge zu Gesundheitsschädigungen führen (Asbestose, Lungenkrebs, Mesotheliom).It is known that asbestos materials in fiber form Inhalation into the lungs can damage health (Asbestosis, lung cancer, mesothelioma).

Es wurde gefunden, daß durch eine thermische Behandlung von Chrysotil und Krokydolith unter gleichzeitiger mechanischer Beeinflussung ein Zerfall der Fasern oder auch Sintern der Fasern stattfindet, wodurch die gesundheitsschädigende Wir­ kung neutralisiert wird.It has been found that by thermal treatment of Chrysotile and crocidolite with simultaneous mechanical Influencing a disintegration of the fibers or sintering of the Fibers takes place, causing the health damaging we neutralization.

Die bei diesen Prozessen gewonnenen Endprodukte können um­ weltfreundlich z.B. in Baustoffen oder als Grundmaterial für die Gewinnung von Wertstoffen verwendet werden.The end products obtained in these processes can world friendly e.g. in building materials or as basic material be used for the extraction of valuable materials.
