introduction of Si 4000 xenon lamp aging test chamber

The Si4000 xenon lamp aging tester is a fully automatic closed-loop control aging tester with a large LCD touch screen display, which can simultaneously control light irradiation, blackboard temperature, chamber temperature, chamber humidity, spraying cycle, running time and other control parameters, and the controller has a dozen programs preset at the factory, and the user can also program three programs, after the program is called and executed, that is, fully automatic operation, without manual monitoring. The Si4000 lamp power is 6500 W. In the natural aging environment, the specimen is mainly exposed to radiation with wavelengths between 300-800 nm, and the Si4000 can select 340 nm, 420 nm and 300-400 nm as monitoring points to control the radiation intensity there.


VIII. Blackboard humidity control

Si4000 through the relative humidity sensor for automatic proportional closed-loop control of the box humidity, it uses compressed air to stir pure water through a fine nozzle to form a water mist to humidify, this humidification method is rapid and safe, and the angle of the nozzle adjustable.

Certain brands of machines humidification method is the use of heating humidification, the defects of this method is the response lag, deviation, while the heat brought in by the moisture will seriously affect the box.

Nine, temperature balance control

Spraying control.

Si4000 can independently control the front spraying and back spraying, the front spraying mainly simulates the process of rain in nature, while the back spraying simulates the phenomenon of surface condensation at night.

Light and dark cycle control.

Si4000 can independently control the on and off of the lamp, which represents night and day respectively.


X. Instrument description

Lamp life: It is recommended to replace the lamp every 2000 hours, and the filter also needs to be replaced regularly. Qinsun provides a 4000-hour spare parts package, which can be selected according to different combinations of internal and external filters. The kit contains two lamps and a number of internal and external filters and other consumables, sufficient for a 4000 hour test.

The Si4000 lamp is positioned upright in the center of the chamber around a three-tiered rotating sample holder for 65 samples (sample size 70x145x3mm), which ensures that each sample is subjected to a uniform radiation intensity. Each sample is lined with an aluminum plate, and if there are not enough samples to fill the rack at a time, the empty sample holder is lined with an aluminum plate and the entire rack is hung.

The Si4000 is a water-cooled xenon lamp aging instrument, in which the internal and external filters filter light while forming a water jacket, in which the flow of pure water is used to carry away the enormous heat generated by the xenon lamp when it emits light.

XI. Scope of application

Si4000 is mainly used for testing of automotive materials, plastics, paints, packaging, solar photovoltaic, textile industry including geotextiles, pigments, stabilizers, additives, etc.
