Why test the thermal shock resistance of glass bottles?
The thermal shock resistance of glass bottles refers to the ability of glass bottles to withstand sudden temperature changes without breaking. Glass bottles will be impacted by drastic temperature changes when they experience the impact of production line filling and climate change. Glass bottles with substandard thermal shock resistance are easily broken after such impact. Therefore, the thermal shock resistance of glass bottles is also a must-check item for glass bottle manufacturers and users.
What is thermal shock in glass bottles?
Rapid temperature changes to which a material is subjected, known as thermal shock. Thermal shock resistance refers to an important index for evaluating the damage resistance of a material when it is subjected to rapid temperature changes. The closer the test values are, the higher the precision. Conversely, the lower the precision is the ability to resist damage. If the thermal shock resistance of the glass bottle is low or does not meet the standard requirements, new cracks will be generated in the thermal shock, as well as cracking, spalling, and fracture caused by the expansion of new cracks and original cracks. The above phenomena are called thermal shock damage. . The existence of thermal shock damage can cause the bottle container to rupture during transportation, storage or refrigeration, which can lead to safety accidents in severe cases.
