EFFECT OF GLOBULAR CARBON ADDITION ON RHEOLOGICAL PROPERTIES OF COAL-WATER SUSPENSION

The physical-mechanical properties was studied for the composite material (the highly concentrated suspension based on distilled water, ultra fine brown coal, nano particles of the globular carbon T-900). It was found that carbon nano particles at low concentrations (0.04, 0.08 2 wt.%) can be dispersing agents. Under certain cavitation modes the surface segrega-tion of oxygen impurities was detected in the nano carbon particles. The combustion kinetics of dispersed phase powder of suspension with the addition of 2 wt.% nano carbon differs from the original coal combustion.

Key words: composite materials, polymer nano composites, carbon nano modifiers, surface seg-regation, hydrodynamic cavitation
