Description
(54) СПОСОБ ИЗМЕРЕНИЯ ТЕПЛОЕМКОСТИ ПОЛИМЕРНОГО(54) METHOD OF MEASUREMENT OF POLYMERIC HEAT CAPACITY
МАТЕРИАЛАMATERIAL
Изобретение относитс к теплометрии и может быть использовано при изучении теплофизических свойств полимерных материалов.The invention relates to calorimetry and can be used in the study of the thermophysical properties of polymeric materials.
Известен способ определени теплоемкости , при котором теплоемкость какого-либо вещества определ ют путем передачи определенного количества тепла от нагревател к образцу исследуемого материала и измерени соответствующего изменени температуры образца. При этом количество переданного тепла определ ют либо непосредственными измерени ми мощности, выдел емой нагревателем, либо по эталонному образцу с известными характеристиками t A known method for determining the heat capacity in which the heat capacity of a substance is determined by transferring a certain amount of heat from the heater to the sample of the material under study and measuring the corresponding temperature change of the sample. In this case, the amount of heat transferred is determined either by direct measurements of the power released by the heater or by a reference sample with known characteristics t
Недостатком известного способа вл етс то, что при таких измерени х трудно избежать потери тепла через контактные сопротивлени при передаче его от нагревател к исследуемому образцу.The disadvantage of this method is that with such measurements it is difficult to avoid heat loss through contact resistances when transferring it from the heater to the sample under study.
Наиболее близким к изобретению техническим решением вл етс способ определени теплофизических свойств материалов, заключающийс в нагреве образца и измерении изменени температуры 2.The closest technical solution to the invention is a method for determining the thermophysical properties of materials, which consists in heating the sample and measuring the temperature change 2.
Однако обработка результатов измерений и расчет теплофизических параметров вещества очень трудоемки и требуют построени градуировочных графиков дл каждого исследуемого вещества.However, the processing of measurement results and the calculation of the thermophysical parameters of a substance are very laborious and require the construction of calibration curves for each test substance.
Целью изобретени вл етс упрощение и ускорение процесса измерени теплоемкости.The aim of the invention is to simplify and accelerate the process of measuring the heat capacity.
