The service life of the UV lamp
What is standard of the service life of the UV lamp? The service life of the UV lamp is based on the attenuation of ultraviolet radiation from the standard.
Generally the international standard general use time, low power density of the tubes, power density of 40 ~ 80 w/cm, service life of more than 1000 h, industrial developed countries will to standard product for 2000 h. Tube and high power density, power density is more than 80 w/cm, the service life of 600 ~ 800 h.
It should be noted that the service life of the tube to reach deadline is not representative can't continue to use, only refers to the tubes of the same energy input can use ultraviolet intensity is not enough, that is to say, uv output power is low, energy loss.
In practice on the basis of whether curing. But want to consider the overall cost, after all, if extended dry cure time, reduces the production efficiency.
