Effect of discontinuous and dilatant viscosity behavior in structured oxyhdrate gel systems

The effect of dilatancy in oxyhydrate gel systems is determined by the resonance, in which case the vibrations of gel density superimpose on the rotations in the D-region and one of the polarization vectors increases sharply. It is observed in the discontinuous sections of experimental curves of the complete rheological curve. above-mentioned D-region, significant structural changes take place. The dilatant discontinuity in the complete rheological curve is first of all determined by geometric sizes of gel pacemakers. Small-diameter pacemakers favour the periodic compression of gels, their polymer bond, ordering and increase in the rate of gels flow, while large-diameter pacemakers (12 × 10−6 m and larger) provoke the ‘swelling’ of gels. The latter indicates the formation of the amorphous unstructured substance, which decreases the flow rate.
