由于热水器电热管经常与人体直接接触,因此对使用电热管的电气性能要求非常严格。所以对电热管的封口是一道十分重要的工艺和控制内容,电热管最终品质的稳定与可靠性在此过程中有着举足轻重的影响力。

目前电热水器电热管在封口上有下面几种方式:1.对于使用中低温镁粉制作的电热管一般采用自然固化的环氧胶水和RTV硅胶加绝缘子进行封口,由于中低温镁粉本身具有防潮性,因此这种封口方法能够保证使用要求。2.对于使用高温镁粉制作的电热管一般采用高温过炉或烘箱高温排潮后,管口封装环氧AB胶水进行固化后再进行RTV硅胶或RTV硅胶加绝缘子进行封。

Because the water heater electric heating tube电热水器电热管 often in direct contact with the human body, so on the electrical properties of the use of electric heating tube电热管 very strict requirements. It is a process and control is very important content of electric heat 电热管sealing, has play a decisive role influence stable electric heating tube final quality and reliability in the process.
At present, the electric water heater electric heating tube 电热水器电热管has the following several ways on the closure: 1 for heating low temperature powder used in pipe generally use the natural curing epoxy glue and RTV silica gel and insulator seal, because of the low temperature powder itself has moisture resistance, so this method封口方法 can guarantee the sealing requirements. 2 for heating high temperature magnesium powder tube produced by high temperature furnace or oven generally high temperature exhaust pipe package AB glue, epoxy curing after RTV silica gel or RTV gel and insulator seal.
