目的 稳定啤酒企业使用的可回收玻璃啤酒瓶的物理力学性能，增加瓶体表面美观及光滑度，减少重复使用过程中爆瓶的概率，保障消费安全。方法 通过模拟消费周转环节，在回收旧啤酒瓶清洗后到灌装前磨损最严重的灌装线上，加装研发的设备，将一种安全的氧化OPE蜡乳液均匀涂覆在瓶体表面，并重复灌装—周转—清洗—灌装整个循环过程，采集试验数据。结果 通过采集各循环轮次中试验组和对照组的测试数据分析可知，经过工艺改进后的试验组，每轮次都直观可见瓶体表面明亮如新瓶，其物理力学性能各项检测指标明显优于对照组的，试验组的重复使用次数比对照组的增加了2.5倍以上。结论 该工艺可以有效降低回收旧啤酒瓶的表面摩擦因数，改善清洗后瓶体表面的滞涩现象，减少接触磨损对瓶体产生的伤害，延缓力学性能的衰减速度，达到循环经济提倡的增加同目的重复使用的频次，减少新瓶的使用量和成本。同时为修订后的新GB 4544—2020《啤酒瓶》中增加的可回收旧瓶指标要求提供稳定质量的工艺支持。

The work aims to stabilize the physical and mechanical properties of recyclable glass beer bottles used by beer enterprises, increase the beauty and smoothness of the bottle surface, reduce the probability of bottle bursting during reuse, and ensure consumption safety. By simulating the consumption turnover link, the researched and developed equipment was assembled onto the filling line with the most serious wear after recycling old beer bottles after cleaning and before filling. A layer of safe oxidized OPE wax emulsion was applied to the bottle surface. The entire cycle process of filling-turnover-cleaning-filling was repeated to collect test data. By collecting and analyzing the test data of the test group and the control group in each cycle, in the test group after the process improvement, the bottle surface was as bright as a new bottle in each round. Their physical and mechanical properties were significantly better than those of the test group. In the control group, the number of repeated use increased by more than 2.5 times compared with the control group. This process can effectively reduce the surface friction coefficient of recycled old beer bottles, improve the stagnation phenomenon on the bottle surface after cleaning, reduce the damage to bottles caused by contact wear, delay the decay speed of mechanical properties, and increase the same-purpose use frequency advocated for circular economy and reduce the use and cost of new bottles. At the same time, it provides stable quality process support for the index requirements of recyclable old bottles added in the revised new GB4544-2020 Beer Bottles.
