METHOD OF MAKING CARBON RIBBONS AND DEVICE TO ITS IMPLEMENTATION Russian patent published in 2008 - IPC D01F9/22 D01F11/16 

FIELD: chemistry.

SUBSTANCE: present invention pertains to production of high-strength and high-modulus carbon ribbons, obtained from polyacrylonitrile threads and can be used for making high-tech composites. The method of making the ribbons involves putting the polyacrylonitrile threads on a textile machine, weaving a ribbon on the textile machine, thermal stabilisation of the obtained ribbon, carbonisation, electrochemical treatment, textile finishing and winding. Before thermal stabilisation, from 0.25 to 0.90 of the output of the textile machine per hour is accumulated. All operations take place in continuous mode. The production line for the given ribbons comprises furnaces for thermal stabilisation and carbonisation, apparatus for electrochemical treatment and textile finishing, a winding machine and equipment for transportation of the ribbons, fitted between the elements of the production line. Before the thermal stabilisation furnace, there is bobbin holder with warper's bobbins, textile machine and ribbon accumulator.

EFFECT: higher output due to longer operation between replacements (increased running time of the equipment).
