Glass bottle cold and hot sudden change testerDesign based on the physical principles of thermal expansion and contraction. When glass bottles undergo rapid temperature changes, the degree of expansion or contraction inside and outside is inconsistent, resulting in thermal stress. If this stress exceeds the bearing limit of the glass material, the glass bottle may experience problems such as breakage and cracking. The tester sets the temperature of the high-temperature and low-temperature tanks to quickly transfer the glass bottle between them, simulating the possible temperature changes that may be encountered in actual use, and evaluating its heat and cold resistance.

　　Glass bottle cold and hot sudden change testerWidely applied in multiple fields, including but not limited to:

Pharmaceutical industry: Medicinal glass bottles often face the challenge of temperature changes during production, sterilization, transportation, and use. For example, the high-temperature sterilization process needs to withstand the conditions of steam sterilization at 121 ℃ or dry heat sterilization at 250 ℃; Microcracks may occur during transportation and storage due to sudden temperature changes, which can lead to drug contamination or leakage risks. The thermal shock tester can verify the temperature resistance of glass bottles, ensuring that they comply with the technical specifications of the Chinese Pharmacopoeia and YBB standards.

Food and beverage industry: Beer bottles, beverage bottles, etc. may experience drastic temperature changes during transportation, storage, or use (such as direct heating after refrigeration or rapid cooling after high-temperature sterilization). If there are defects in the glass material or structural design, sudden temperature changes can cause internal stress imbalance, leading to safety accidents such as rupture and bottle bursting. The thermal shock tester can evaluate the thermal shock resistance of glass bottles and protect consumer safety.

Chemical industry: Some chemical products require the use of glass bottles for storage and transportation, and these glass bottles also need to have good resistance to thermal shock. The thermal shock tester can be used to test the thermal shock resistance of chemical glass bottles, ensuring their safety in practical use.
