I bought a water heater after a period of time, there is a vacuum tube turned white, how is it?
Vacuum tube leak, it should be bad, if it does not affect the normal use, you can not change, but sooner or later to change, if the time is not necessary for a long time, it is a long time
There are many reasons for vacuum tube ruptureIf there is a nozzle and round head part of the deep mouth, deep mouth surface, it can be concluded that the glass tube stress caused by vacuum, is a quality problem.If the uneven surface of the mouth, may be caused by collision.
Transparent, barium magnesium has is the oxidation reaction with air, consumed, that a lot of air into the vacuum tube, can be identified as the vacuum pipe leakage, may be due to tube rupture caused by.
The top is the original silver mirror, this is to guarantee the vacuum in the vacuum tube, but using evaporable getter, active metal containing large amounts of magnesium, barium, metal tube attached to evapotranspiration in the vacuum of the round part of the inner surface of the outer tube, forming a silver mirror
