1. Principle:

Xenon lamp aging tester and UV aging tester are more widely used accelerated aging test equipment, the two test equipment testing principle is completely different. Xenon lamp aging tester simulates all the spectrum of sunlight, including ultraviolet (UV), visible light and infrared (IR), xenon lamp spectrum in the range of 295nm to 800nm basically coincides with the spectrum of sunlight. This means that xenon lamps are used to test many products that are sensitive to the long wavelengths of UV, visible light and IR. UV weathering chambers, on the other hand, use fluorescent UV lamps to mimic the damaging effects of sunlight on durable materials. This is different from the xenon arc lamps mentioned earlier, fluorescent UV lamps are electrically similar to the general lighting cold fluorescent lamps, but can generate more ultraviolet light rather than visible or infrared light.

2. Use:

Xenon lamp aging tester adopts xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments, which can provide corresponding environment simulation and accelerated test for scientific research, product development and quality control. And, the UV aging tester mainly adopts fluorescent UV lamp as the light source, and accelerates the weathering test of materials by simulating the UV radiation and condensation in natural sunlight, in order to obtain the results of material weathering. It can simulate the environmental conditions such as UV, rain, high temperature, high humidity, condensation, darkness, etc. in the natural climate, by reproducing these conditions, combining them into one cycle and letting it perform automatically to complete the cycle times.

Water cooling is a method to dissipate the heat generated inside the xenon aging tester through a water cooling system. The water cooling system consists of a water pump, a water tank, a radiator, etc. The principle is that the coolant containing the heat generated inside the xenon aging tester is cooled by the radiator. The coolant used in the water cooling system is usually pure water or water with added preservatives.

1. Advantages of water cooling

(2) Low noise: water-cooled compared to air-cooled, the noise is much smaller. Because water-cooled is through the water pump will coolant circulation flow, will not be like air-cooled as produce a lot of noise.
(3) Stable cooling effect: the cooling efficiency of water-cooled system is stable and not affected by the external environment, which can adapt to different application requirements in a wide range.

2. Disadvantages of water cooling

(1) Relatively difficult to install and use: water-cooled systems require high installation and use of skills, and need professional engineers for maintenance and overhaul.
(2) High maintenance costs: water-cooled cooling system has more components, which requires frequent inspection and cleaning, and higher maintenance costs.

When choosing the cooling method of xenon lamp aging tester, the following factors need to be considered:

1.  Power Consumption: when the test chamber power consumption is high, water cooling is more suitable, more efficient heat dissipation.
2. Noise: when the test chamber is used in the requirements of low noise occasions, it is recommended to choose the water-cooled method.
3. Installation and Maintenance: water cooling requires high installation and maintenance skills, it is recommended to choose in the case of installation and maintenance by professional engineers.
4. Price: In the case of higher budget, you can choose water cooling, but also need to bear higher costs.

In summary, the choice of xenon lamp aging test chamber cooling method needs to be weighed according to the actual situation. In order to ensure the normal operation of the equipment, it is recommended that when choosing the heat dissipation method, the power of the equipment, noise, price and maintenance costs and other factors should be considered.

The procedure for using the xenon lamp weather tester consists of the following main parts:

Sample Placement: Firstly, the samples to be tested are placed in the sample racks in the chamber, ensuring that the samples are evenly exposed to the light and do not block each other. For cases where multiple aspects of weathering need to be assessed, the samples should be placed at different angles to simulate various situations in actual use.

Equipment start-up: The equipment is started and the test begins according to the preset programme. During the test, a xenon lamp will irradiate the sample to simulate natural daylight, while the temperature and humidity inside the chamber are controlled to replicate conditions in a natural environment. Ensure that the operational status of the equipment and any abnormal changes in the sample are checked periodically during the test.

Periodic Inspection: Periodic inspection of the samples is necessary during prolonged weathering tests. Record changes in the appearance of the samples such as colour, gloss, cracking and blistering, as well as changes in physical properties such as hardness and strength. These data will provide an important basis for analysing the weathering performance of the material.

End test: After completing the test according to the set test cycle, switch off the equipment and remove the sample. The samples are examined in detail and tested for performance, and the status and performance data are recorded. Comparisons are made with the initial data prior to testing to assess the weathering performance of the material.

Data Analysis and Reporting: Collate all data and observations collected during the test. Analyse the changes in the material’s performance under xenon lamp exposure to determine the strength of its weathering resistance and prepare a detailed test report. The report should include the test conditions, the course of change in the sample, the results, and recommended improvements.

Through the above steps, weathering tests using a xenon lamp weathering tester can systematically and accurately assess the stability and service life of materials in their natural environment.

The installation process of the xenon lamp weather tester mainly includes the following steps:

Water supply and drainage connection: After the power supply of the whole machine is turned on, it is necessary to connect the water inlet pipe to the drainage pipe and make sure that the pressure in the water supply system is not less than 0.5 kg. If the pressure is less than 0.5 kg, a self-priming pump or a pipeline pump should be added to the water inlet system in order to increase the water pressure. The exhaust pipe should be connected to the outside, but do not bend or raise it.
Control system setup: Press the ‘power’ switch, the xenon lamp light and rainfall time controller on the power display. Set the total test time and rainfall time. After the time parameters are set, switch off the ‘power’ switch, then switch on the ‘power’ switch again, press the ‘start’ switch, the internal indicator light. The ‘Power’ indicator lights up and the ‘Dry Bulb Temperature’ and ‘Wet Bulb Temperature’ are displayed. First of all, in the ‘wet and dry bulb control table’ with the manual, just set the ‘dry bulb temperature’ value, and then check the corresponding humidity value, with the dry bulb temperature value minus the temperature difference between the value obtained as ‘wet bulb temperature ‘value, set this value in the wet bulb instrument, to work in the ‘dry bulb temperature’ and ‘wet bulb temperature’ constant, that is, the temperature and humidity constant.
Xenon lamp installation and start: first press the power switch on the irradiometer, press the ‘xenon lamp’ switch, the switch in the indicator light, within five seconds the xenon lamp automatically triggered to light, to the xenon lamp time to set the value of the automatic switch off. If the xenon lamp does not start, you can start the xenon lamp for the second time, but need to wait 10 minutes to try again.

In addition, careful attention should be paid when replacing the xenon lamp of the xenon aging test chamber, the lamp installation method is as follows: open the top plate, remove the two wires on the epoxy board and take out the lamp. Take down the lamp holder, check whether the casing on the two ends of the fixed frame is straight. Wearing gloves, pick up the lamp (gently) and thread the lamp from the holder to the other end of the holder, care and attention must be taken during the installation process.

These steps together constitute the complete installation process of the xenon lamp weather tester, ensuring the correct installation of the equipment and the smooth running of subsequent tests.
