Embodiment

[0031] Such as figure 1 As shown, the automatic test system of the vacuum stability of the present invention comprises a constant temperature bath device, and the constant temperature bath device is the same as the constant temperature bath device currently used for the sample to be tested to be heated by a constant temperature bath, including a constant temperature bath furnace body 5 and a temperature Control cabinet6. Described constant temperature bath furnace body 5 is connected on the temperature control cabinet 6, puts into the constant temperature bath furnace body 5 after the test tube with the sample to be tested is evacuated during use, and the constant temperature bath furnace body 5 is heated by the temperature control cabinet 6, The test tube can then be heated in a constant temperature bath.

[0032] In order to realize automatic control, the temperature control cabinet 6 can automatically control the heating temperature and the heating time to the constant tem...

Abstract

The invention discloses a vacuum stability test system and relates to an automatic test system for vacuum stability. The automatic test system for vacuum stability comprises a constant-temperature bath device and is characterized by also comprising a deflating quantity test device (1) and an automatic control device, wherein the constant-temperature bath device and the deflating quantity test device (1) are electrically connected with the automatic control system. The invention also discloses an automatic test method for vacuum stability. The automatic test system for vacuum stability is simple in structure and convenient to use, adopts the preset program to test a test sample, record, calculate and process data and can guarantee the accuracy of the test data, so that the test result can accurately embody the performance of sample materials and the automatic test system for vacuum stability is suitable for popularization and use.

Description

technical field [0001] The invention relates to a vacuum stability testing system, in particular to an automatic vacuum stability testing system and a testing method thereof. Background technique [0002] Vacuum Stability Test (VST) was proposed by Farmer in England in 1920. The basic principle of this method is to heat a certain amount of sample under the conditions of constant volume, constant temperature and certain vacuum degree to conduct thermal decomposition test. The pressure sensor is used to convert the gas pressure change into an electrical signal to measure the volume of the thermally decomposed gas, and then convert it to the volume under the standard state according to the gas law. The volume VH (i.e. the amount of outgassing) of the released gas after the unit mass of the agent is heated is used as the vacuum stability data of the energetic material to express the stability of the energetic material. Since the vacuum stability test is carried out under the co...
