Water-cooled xenon lamp aging test chamber water purity requirements

It is understood that the use requirements of the water-cooled xenon lamp aging test chamber are much higher than those of the air-cooled xenon lamp weathering test chamber, and pure water equipment is required, while the air-cooled xenon lamp weathering test chamber uses tap water for spraying
.

What are the requirements for water purity in water-cooled xenon lamp aging tanks? The purifier effluent is mainly used to cool the lamp, if the water quality is not good, it will produce scale, affecting the irradiation
of the lamp.

1.
For the lamp cooling water, this piece must be deionized water, must not use tap water without authorization, strict requirements for conductivity below 5us / cm, because the trigger of the xenon lamp will produce large currents and high voltages, if the use of high conductivity of water, then when the lamp trigger will cause damage to the lamp, the temperature of the two inlet inlet must be lower than 35 ° C, because the water temperature is too high will also shorten the life of the xenon lamp, so there must be a closed cold water system and filtration system when using circulating water, Ensure secondary contamination
of water quality due to cooling.

2.
Water-cooled xenon lamp aging test machine spraying, humidification of the water must be distilled water, such as the use of general tap water sample surface will be wrapped in white substance, if the purpose of irradiation is not achieved, this substance is the impurities in the water after evaporation to form a crystal called calcium and magnesium, so this requires the use of distilled water to ensure the consistency of irradiation, to achieve testing
