High molecular material thermal stability tester

Abstract

The invention provides a high molecular material thermal stability tester and belongs to the field of testing of high molecular stability. The high molecular material thermal stability tester comprises a heating device, a container and an electronic control system. The heating device comprises a heating body and a vibrating table, the heating body and the vibrating table are electrically connected with the electronic control system, and the heating body is arranged on the vibrating table; the container is internally provided with a plurality of test tubes and sample grooves, the sample grooves are fixedly connected with the container, the sample grooves are provided with mesh holes, and the interiors of the sample grooves are communicated with the interior of the container through the mesh holes. According to the high molecular material thermal stability tester, the sample grooves are utilized to fix the test tubes, the test tubes are prevented from waggling in the container, both hands of an experimenter are liberated, the test tubes are heated in the sample grooves, and meanwhile the vibrating table conducts vibration continuously, so that a solution in the container and materials in the test tubes are heated uniformly, the heating effect is good, and accuracy of tested thermal stability data and the result is high.

Description

technical field [0001] The invention relates to the field of measuring devices for polymer stability, in particular to a thermal stability tester for polymer materials. Background technique [0002] When measuring the thermal stability of polymer materials, the material needs to be heated evenly and cannot be locally heated. The existing thermal stability tester places the test tube in the oil bath of the container for heating through the clamp, and the opening of the container is large. Place the test tube In the container, the experimenter needs to hold the clip at any time to prevent the test tube from falling into the container, and the user also needs to shake the test tube constantly to ensure that the materials in the test tube are heated evenly. Long-term operation is likely to cause sore arms. And the heating effect is not good, and there is a deviation in the thermal stability temperature of the measured material. Contents of the invention [0003] The invention...
