Glass bottle breakage is often encountered in daily production and life. For example, beer bottles and white wine bottles for production and transportation are damaged and cracked, some glass bottles fall to the bottom during use, and one of the bottles slightly collides with each other and breaks. Perhaps everyone is accustomed to it and doesn't find it strange, let alone seriously considering it. Is this normal? What is the reason for this?

Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., as a professional manufacturer of glass bottle testing instruments, analyzes the problems encountered by customers:

During the annealing process of glass products, if the cooling speed is too fast during the cooling stage, it is easy to generate significant stress on the product, which is mainly reflected in the cooling stage of the annealing furnace.

If the temporary stress during the cooling stage in the annealing furnace exceeds the strength limit of the product, the product will fracture in the annealing furnace. In general, if it is frequent and frequent There are many instances of product breakage, which may be caused by temporary thermal stress due to the rapid cooling rate of the product during the cooling process.

Microcracks caused by glass products during the forming process, as the microcracks on the surface of the product can reduce its strength and withstand stress during annealingliveIt inevitably fractures due to temporary thermal stress. In this case, a thermal spray or cold spray protective layer should be used to prevent the glass bottle from breaking easily.

The places where stress is more concentrated are usually at the junction of the bottle bottom and body or at the bottle mouth, and the bottom falling or the bottle mouth breaking is usually caused by stress concentration. Of course, secondary annealing or slow cooling is an effective way to eliminate stress during the manufacturing of glass bottles.

But for enterprises that use glass bottles, they cannot control the production process of glass bottles, but necessary testing is still required for the internal stress of glass bottles.likeBeer Bottle（GB 4544-2020）The standard stipulates that the internal stress of beer bottles should be less than4Grade.GB/T 24694-2021The specified internal stress in the quality requirements of glass container Baijiu bottle<4Grade.2015The internal stress of glass products specified for pharmaceutical packaging materials is less than or equal to40nm/mmTo meet the standard requirements, it is necessary to use professional means to control product quality.
