METHOD FOR RESEARCHING THERMO-DYNAMIC STRUCTURE TRANSFORMATION OF LIQUID SUBSTANCES Russian patent published in 2006 - IPC G01N25/00 

FIELD: technology for researching viscosity properties of liquid using heat means.

SUBSTANCE: in accordance to method, sample of liquid with volume ≤1ml is cyclically, monotonously and continuously cooled down and heated in given temperature spectrum at given speed. In each successive cycle liquid structure transformation temperature areas are determined on basis of dimensionless dynamic criterion of likeness of temperature-viscosity properties ηδ, expressing dependence of relative change of shift viscosity on relatively change of absolute temperature of liquid at given speed of its temperature alteration, and level of intensiveness of structural transformation of liquid being studied in aforementioned temperature areas is expressed quantitatively through either change of thermo-energetic function of liquid E(T), or through change of free activation energy ε(T). temperature and viscosity are determined by means of low frequency vibro-viscosity gage.

EFFECT: increased precision of research.
