METHOD OF MANUFACTURING PRODUCTS FROM GRAPHITE-CONTAINING NANOCOMPOSITE AND TRIBOCHEMICAL DISPERSER FOR ITS REALISATION Russian patent published in 2014 - IPC C01B31/04 B82B1/00 C04B35/52 B01F3/18 B01F13/06 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: graphite-containing component is mixed with a kaolin-based filling agent, dry mixing with simultaneous dispersion successively in a drum and centrifugal mixers is carried out. After that, a magnetised water solution of an alumoborophosphate concentrate, containing a surface-active substance, is introduced, and a wet batch in a screw mixer is carried out. After that, the obtained mass is processed in a tribochemical disperser under conditions of vacuuming and all-around compression to a pressure of 5-20 MPa. The tribochemical disperser includes a hermetic hollow cylindrical case 40, which has flanges 41 and 42 on butt ends, a permeable piston 44 with a rod 45, a drive 46 of reciprocating movement, means for the cavity vacuuming 43, two vacuum gate valves 471 and 472. The piston 44 represents a packet of adjoining each other pairs of metal nets which have the different cell size, located between two protective grids 445. The products are moulded from processed mass with their further thermal processing.

EFFECT: reproducibility of specific electric resistance in the products is provided, with the nanocomposite mass acquiring isotropic properties and ductility.
