Description
Известны приборы типа калориметра, в которых количество теила, прошедшего через стенки калориметрического сесуда, определ ют по количеству образовавшегос пара калориметрической жидкости, подоjpeB которой осуществл ют при помошк иагревае.мой жидкости с более высокой температурой кипени .Instruments of the type of calorimeter are known, in which the amount of teil passed through the walls of the calorimetric sesuda is determined by the amount of the resulting vapor of the calorimetric fluid, the bottom of which is carried out with help of hot fluorescent fluids.
Описываемое изобретение представл ет собой прибор дл оиределени коэффициента теплопроводности твердых, негигроскопичных материалов , в котором количество тепла, протекшего через испытуемое тело, определ ют по количеству тепла, затраченного на испарение определенного объема жидкости.The described invention is a device for determining the coefficient of thermal conductivity of solid, non-hygroscopic materials, in which the amount of heat that has passed through the test body is determined by the amount of heat spent on the evaporation of a certain volume of liquid.
Дл снижени потерь тепла и исключени вли ни на их величину температуры нагревател калориметрический сосуд выполнен из испытуемого материала.To reduce heat loss and eliminate the effect on their heater temperature, the calorimetric vessel is made of the test material.
На фиг. 1 схематически изображен описываемый прибор; на фиг. 2 - температурный график дл определени коэффициента теплопроводности .FIG. 1 shows schematically the described device; in fig. 2 is a temperature graph for determining the thermal conductivity coefficient.
Сосуд /, снабженный мешалкой 2 с электроприводом 3 и термометром 4, заполнен насыщенным раствором поваренной соли, температура кипени которого равна 108. Подогрев раствора производ т при помощи электрического нагревател 5.The vessel /, equipped with an agitator 2 with an electric actuator 3 and a thermometer 4, is filled with a saturated sodium chloride solution, the boiling point of which is 108. The solution is heated with an electric heater 5.
Сосуд 6 выполнен из материала, коэффициент теплопроводности которого определ ют, погрузив его полностью в жидкость, заполн ющую сосуд /.The vessel 6 is made of a material whose thermal conductivity coefficient is determined by immersing it completely in the liquid filling the vessel.
Сосуд 6 заполнен определенным количеством дистиллированнойThe vessel 6 is filled with a certain amount of distilled
