sealing part life and temperature
The temperature of the sealing part should not be heated above 350 degrees Celsius
1. After the molybdenum foil is heated and expanded, it will affect the sealing with the glass, and then a slow vacuum leakage will occur.
2. The high temperature environment will easily break the sealing part and shorten the service life of the lamp tube.
The power/current value of the infrared heating lamp, the distance between the filament and the sealing part, and the ambient temperature have a great influence on the sealing of the sealing part.
