Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal shock resistance tests, in particular to a glass bottle thermal shock test device based on an intelligent sensor and a test method. BACKGROUND

[0002] Thermal shock refers to a large amount of heat exchange in a short period of time due to rapid heating or cooling, causing a sharp change in temperature and causing the object to be subjected to thermal stress. When a glass bottle is subjected to thermal shock, it has the potential threat of breaking. Therefore, when producing glass bottles, thermal shock tests need to be performed on glass bottle samples.

[0003] Similarly, some glass materials, such as high borosilicate glass, quartz glass, and other new material glasses, can also be tested for their performance through thermal shock tests. High borosilicate glass has a very low thermal expansion coefficient, about one-third of that of ordinary glass. It reduces the impact of temperature gradient stress and has stronger anti-fracture performance. Because high borosilicate glass materials need to be tested at higher or lower temperatures during thermal shock tests, quartz glass materials have good thermal resistance, so their cold resistance is mainly tested. Other new materials made of glass can also be tested for their performance through thermal shock tests.

[0004] Currently, when using a thermal shock test device to test glass bottles, the glass bottle samples (which can be glass material fragments) are first heated in a hot water tank. Then, the heated glass bottle samples are placed in a cold water tank to receive thermal shock. However, when the glass bottles are heated and moved into the interior of the cold water tank, the test basket carrying the glass bottles and the surface of the glass bottles will contain some hot water, which will directly enter the cold water tank. This not only causes the water in the hot water tank to continuously decrease, but also requires frequent addition of hot water to the hot water tank after a long period of use. It also weakens the thermal shock test effect of the glass samples in the cold water tank.

[0005] According to the related technology in the above, the inventors believe that the prior art has the defect of inaccurate measurement. SUMMARY
