(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

将灌封好的20只丁基防水嵌缝密封胶再次测其吸合、释放电压，静合、动合接触电阻，测试结果在表1中列出。不难发现，所有丁基防水嵌缝密封胶均未出现间题。接着对24只丁基防水嵌缝密封胶进行耐压和绝缘测试，测试条件与封胶前完全一样，结果2U只丁基防水嵌缝密封胶全部合格。

为了进一步检查光热两固型密封胶在丁基防水嵌缝密封胶上的试用情况，我们又抽取1,5.14,15.24号丁基防水嵌缝密封胶按照JC--3F丁基防水嵌缝密封胶标准做寿命实验，结果全部合格(均大于1次)。

最后将剩余的15只丁基防水嵌缝密封胶全部拆封，重点观察其渗入的少里胶液是否完全固化。经我们仔细查验，渗入底座四同的少t胶液均已完全固化。

由我们自行配制的改性丁基防水嵌缝密封胶，可以满足继电器生产工艺要求，并成功地应用于JQC-3F丁基防水嵌缝密封胶的堵封。实践证明，这种胶光固时间快，化学德定性好，其渗入的胶且少，且胶液在经过100C11. 5h焙烘后能完全固化。经侧试，它对丁基防水嵌缝密封胶的接触电阻、动作电压，电气寿命、高低温性能均无影响，提高了继电器的投入产出率，而且适合于流水线作业，目前已投入批且生产。

丁基防水嵌缝密封胶是我们在长期的生产实践中，结合我厂通用塑封继电器的特点，经过两年多时间的工艺探索取得的一种将国产光敏胶灵活应用在继电器灌封中的实例。这种工艺缩短了原豁两次培供的时间C3h)，使第一次堵封的时间由1-1.5h减少到30s，加快了工序间的流转时间，提高了继电器的交验合格率.更重要的是减少了继电器的内部污染，提高了成品的投入产出率，可以在塑封继电器中推广使用。www.sdyuantai.com
