|When Zirconium-aluminium Getter is
used in the N2-filled interlayer of a metal halide
lamp to sorb exhaust,it can not be activated by heating
and the getter operating temperature must keep on 400±50℃,Thus,
the getter can sorb exhaust but not sorb N2 continually.
The environment to store getter shall be dry and
clean,and relative humidity lower than 75%,and temperature
lower than 35℃,and no corrosive gases.Once the original
packing has been opened,getter shall be used up soon
and usually it shall not be exposed to the ambient
atmosphere more than 24 hours. Prolonged storage
of getter after the original packing has been opened
shall be always in containers under vacuum or in
a dry atmosphere.
