摘要:
玻璃与金属封接件以其优良的气密性、密封性能、机械强度等综合性能,广泛应用于军品及民品行业中。针对应用于锂亚电池领域的玻璃金属封接绝缘子生产过程中出现的残次品,玻璃封接界面中出现的气泡、漏洞、炸裂等缺陷，分组设计返烧封接试验，通过对多次返烧绝缘子的玻璃状态、封接气密性、抗拉强度、拉伸量、拉拔时间等综合因素的观察和测试，发现多次封接过程中，绝缘子气密性、抗拉强度表现出来的量变趋势与玻璃-金属封接界面表现出的质变状态高度一致：玻璃整体状态较好，绝缘子性能较好。试验结果表明：第一次封接后产品综合性能最高，随着封接次数的增多，玻璃状态、气密性、抗拉强度均有明显下降，产品一致性越来越差；且发现玻璃坯的质地密实、尺寸精准、返烧前对绝缘子进行酸洗表面处理等因素都能有效提高产品封接的综合性能，并通过反复试验确定了保证产品性能的最多返烧次数。
Abstract:
 Glass-to-metal elements are widely used in military and civilian areas because of their excellent air tightness, sealing performance, mechanical strength and other comprehensive characteristics. There are some bad defects such as bubbles, holes, cracks in the interface of lithium battery insulator production. Repeated glass-to-metal seal experiments had been designed and made to analyze and observe the glass state, sealing properties, tensile strength and time of the insulators in this paper. As a result, we get the conclusion that multi-times glass-to-metal seal have great influence on sealing characteristics such as air tightness, tensile strength, etc. With the increasing times of glass-to-metal sealing, the comprehensive performance of the products get worse, and the max repeated seal times which can ensure the products performance have been discussed.
