Qinsun Si4000 Xenon Lamp Aging Machine - China

Qinsun Si4000 xenon lamp aging machine The Si4000 xenon lamp aging tester is a fully automatic parameter closed-loop control aging tester, with a large LCD touch screen display, which can simultaneously control light irradiation, blackboard temperature, temperature in the box, humidity in the box, spray cycle, running time and other control parameters.

The controller has more than a dozen programs preset at the factory, and users can also compile three programs by themselves.

After the programs are called and executed, they run fully automatically without manual monitoring.

Si4000 tube power is 6500W.

In the natural aging environment, the sample is mainly irradiated by light with a wavelength between 300-800nm.

Si4000 can choose 340nm, 420nm and 300-400nm as monitoring points to control the radiation intensity there.

During the test, in order to ensure the reproducibility of the test results ①, the parameters of the test process need to be kept constant, and the radiation intensity of the light source is the main control parameter.

In order to overcome the influence of lamp attenuation and voltage instability on the radiation intensity, Si4000 measures the radiation intensity of the monitoring point through a light sensor, and after comparing the result with the set value, the lamp power is controlled in a closed loop by adjusting the current., To ensure that the radiation intensity of the sample is always constant.

The American standard for outdoor aging uses 340nm as the monitoring point; the American standard for indoor aging uses 420nm as the monitoring point; and the European standard generally uses 300-400nm both indoors and outdoors.

It is recommended to use 340nm as a monitoring point in the host, and 420 as the second monitoring point.

During a certain test, both monitoring points can be monitored, but only one of them can be controlled.

In addition, we recommend buying a 300-400nm optical filter device.

When the 300-400nm monitoring point is needed, the user can modify it by himself, and the host will automatically recognize it after modification.

Generally, when the inner and outer filters are both borosilicate glass, the reading at 340nm is multiplied by 115, which is the radiation intensity in the 300-400nm range.

The testing machine can control the length of the test time by accumulating the radiant energy.

In different real environments and regions, the spectral energy distribution in daylight is in the test standard, and the blackboard temperature is an important control parameter, which represents the high temperature of the surface of the sample when it receives radiation.

When the sample is irradiated, the surface temperature will increase due to the absorption of the infrared energy in the light, and the surface temperature of different colors will be different.

In the aging process, temperature is also an important factor affecting the aging speed.

Because according to the principle of electrochemistry, every 10°C increase in temperature will double the speed of electrochemical reaction.

Therefore, the surface temperature of the sample is also an important control parameter during the test.

Like the sample, the blackboard thermometer is also mounted on the sample holder and hung on the sample rack.

The American standard and European standard commonly used blackboard thermometers are different.

The American standard is called BPT, and the European standard is called BST (Blackboard Standard Temperature).

The American standard blackboard thermometer is a metal plate coated with standard paint, while the European one is based A plastic insulation layer is attached to the back.

Generally, the reading of BST will be more than 5 degrees higher than that of BPT.

In order to comply with different standards, it is recommended to use dual-channel blackboard temperature measurement and control.

The Si4000 lamp tube stands upright in the center of the test box and surrounds the upper and lower three-layer rotating sample rack, which can hold 65 samples (sample size is 70x150x3mm), which ensures that each sample receives uniform radiation intensity.

An aluminum plate should be lined after each sample.

If each sample is not enough to cover the sample rack, the empty sample holder should be lined with an aluminum plate to cover the entire sample rack.
