Изобретение относитс к дилатометрии , а именно к устройствам дл определени коэффициента объемного термического расширени (КОТР) материала в жидком и высоков зком состо нииThe invention relates to dilatometry, namely, devices for determining the coefficient of volumetric thermal expansion (KOTP) of a material in a liquid and highly viscous state.
Известно устройство дл определени КОТР материалов в жидком состо нии , в котором косвенным путам определ ют КОТР в жидком состо нии путем измерени веса платинового тела при погружении его в исследуемый материал , наход щийс в жидком состо нииA device is known for determining the MFR of materials in a liquid state, in which the MFR in a liquid state is determined indirectly by measuring the weight of a platinum body when it is immersed in the material under investigation, which is in a liquid state.
1.one.
Однако это устройство не позвол ет определить КОТР материалов с в зкостью более 10 - 10 . П.However, this device does not allow determining the MWS of materials with a viscosity of more than 10 - 10. P.
Наиболее близким техническим решением вл етс устройство дл определени КОТР материала в жидком и высоков зком состо нии, содержащее весы, сосуд с исследуемым материалом, помещенный в нагревательное устройство Сосуд с помощью подвеса укреплен на одном из плеч коромысла весов и погружен в, солевой расплав 2. The closest technical solution is a device for determining the KOTP of a material in a liquid and highly viscous state, containing a scale, a vessel with the test material, placed in a heating device. The vessel is fixed on one of the arms of the balance arm with a suspension and immersed in salt melt 2.
Недостатками известного устройства вл ютс низка точность определени КОТР, необходимость учета поверхностного нат жени на границе подвес- солевой расплав, невозможность определени КОТР дл веществ химически активных по отнс иению к солевому расплаву.The disadvantages of the known device are the low accuracy of the determination of the CATF, the need to take into account the surface tension at the border of the suspended salt melt, the impossibility of determining the CATF for substances that are chemically active in relation to the salt melt.
Цель изобретени - определение КОТР химически активных материалов, обладающих высоким давлением насыщенного пара.The purpose of the invention is to determine the KOTP of chemically active materials with high saturated vapor pressure.
Поставленна цель достигаетс тем, что сосуд дл исследуемого материа0 ла, выполненный в виде герметичной Г-образной трубки, укреплен с помощью держател на коромлсле весов .таким образом, что сосуд с материалом находитс н.ад обоими плечами The goal is achieved by the fact that the vessel for the test material, made in the form of a sealed L-shaped tube, is reinforced with the help of a holder on the balance rail. In this way, the vessel with the material is located on both shoulders
5 коромысла весов, а расширение исследуемого материала при нахревании происходит в направлении свободного объема отростка Г-образной трубки, оставл емого при заполнении сосуда 5 balance weights, and the expansion of the test material during heating occurs in the direction of the free volume of the process of the L-shaped tube left when the vessel is filled
0 материалом. Дл демпфировани весов м сохранени чувствительности на стрелке последних устанавливаетс противовес.0 material. To dampen the weights and maintain the sensitivity, a counterweight is placed on the arrow of the latter.
На чертеже изображено предлагае5 мое устройство, общий вид.The drawing shows the proposed5 my device, a general view.
Устройство содержит весы 1, на коромысле 2 которых с помощью держател 3 закреплен сосуд 4, выполненный в виде Г-образной трубки, запол0 ненный исследуем:1м материалом 5, соThe device contains scales 1, on a yoke 2 of which with the help of holder 3 a vessel 4 is fixed, made in the form of an L-shaped tube, filled with the test: 1m material 5, with
