DEVICE FOR TESTING DEFORMATION-RELAXATION PARAMETERS OF EASY DEFORMATION MATERIALS Russian patent published in 2005 - IPC

Abstract RU 2266540 C1

FIELD: measurement technology.

SUBSTANCE: device has moisture-thermal system of influence on sample of material and optical system for registration of deformation-relaxation parameters. Moisture-thermal influence system has aid for moistening, heating and cooling of working medium, thermal chamber and aid for supplying working medium into thermal chamber. The latter has to be yoke provided with steam trap. The yoke is made for discharge regulation and change in its position relatively tested sample. Movable cassette with top platform made in form of perforated plate covered with Teflon, is mounted inside thermal chamber. One part of platform for placing sample is disposed directly inside thermal chamber and its second part is disposed outside. The second part is provided with thermo-resistive element having low deformation properties. Control line is marked onto the element. Optical registration system has to be electro-optical system commutated together with microprocessor.

EFFECT: improved precision of shrinkage kinetics.
