METHOD OF RECYCLING FLUOROPLASTS AND MATERIALS, CONTAINING THEM, WITH OBTAINING ULTRADISPERSE FLUROPLAST AND PERFLUOROPARAFFINS Russian patent published in 2014 - IPC B29B17/00 B09B3/00 C08J11/00 C08J11/04 C08F114/26

Abstract RU 2528054 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of recycling a raw material - fluoroplasts and materials containing them, including industrial and operational wastes, in order to obtain ultradisperse fluoroplast and perfluoroparaffins. The method consists in preparation of the raw material and further mixing the prepared raw material with a fluorinating agent at thermal fluoroplast destruction with its simultaneous fluorination at heating.

EFFECT: utilisation of industrial and operational fluoroplast-containing wastes with the elimination of formation of difficult to separate unutilisable and dangerous mixtures, reduction of energy consumption for carrying out the process and reduction of the time for carrying out the process of thermal destruction.
