Apparatus for thermal aftertreatment of carbon fibres from coaltar pitch, in particular from glance- (hard)- coaltar pitch

摘要

in a process for the production of carbon fibers from pitch, the pitch is filtered before being spun and filtering is distilled in a distiller to thin film in order to increase the melting point of more than 200 v. this gives a hard pitch and homogeneous without reformation. mposants infusibles, insoluble in quinoline.the most difficult and most expensive fibre production process, namely, the after heat treatment of extruded fiber pitch can be carried out easily and quickly. heat treatment is further applied to a treatment cycle.
