Light bulb factory tungsten wire why to re-set a layer of molybdenum
So to set a layer of molybdenum and then directly sealed. The glass material is generally made of nickel material
The study found that the use of quartz materials and imported hard material, molybdenum material is a good pressure sealing material, will not cause leakage and other issues,
Especially the quartz material of the bulb, then the heat shrinkage coefficient is not the same as the cause of leakage and the like,
First tungsten wire is used for light, but, if the tungsten directly into the glass,
