METHOD AND DEVICE FOR DETERMINING THERMOPHYSICAL PROPERTIES OF TEXTILE MATERIALS UNDER HIGH TEMPERATURES

摘要

FIELD: measuring equipment.;SUBSTANCE: invention relates to thermometry and is intended for measurement of temperature on inner surface of both single-layer textile material and package of clothes at high temperatures. Disclosed is a device for determining thermophysical properties of textile materials under high temperatures, comprising a metal platform with a movable trolley mounted thereon for securing the replaceable thermal element, a post with a mounted metal axis, to which is bolted steel holder for fixation of tested packet of material and ability to turn it at angle of 90°, in which four measuring probes of thermocouples are inserted, which are connected to digital converters of signals, which supply signal to microcontroller located in wiring housing, on inner side of which there are four digital converters of signals of thermocouples. On the outer side of the wiring housing there is an SD card module for the SD memory card and a potentiometer for servo drive control. Also disclosed is a method for determining thermophysical properties of textile materials when exposed to high temperatures, which consists in determining thermophysical properties of both single-layer material and package of clothes in layers by automated recording of temperature data from four thermocouples located between layers of material, as well as replacement of complex of high temperature sources sources, such as open flame or thermal radiation or contact with heated surface.;EFFECT: possibility of determining thermophysical properties of both single-layer material and package of clothes in layers at different types of thermal effects, as well as device mobility, which enables to perform tests both in test laboratories, and directly in labor protection departments of enterprises operating special clothes.;2 cl, 6 dwg, 1 tbl
