Introduction Of Qinsun Si4000 Xenon Test Chamber - China

Aging definition

In daily use, the material will be exposed to outdoor sunlight, behind glass windows or indoor artificial light for a long time, and physical property changes such as fading, yellowing or strength reduction will occur.

This change is usually called photo-aging or sun-aging.

Significance of aging

In order to evaluate the anti-aging performance of materials more quickly than the natural aging test, test equipment with artificial light sources is usually used to reproduce and accelerate the aging process, so that it will not be affected by daily cycles and climatic conditions, and can get a controllable Test environment to ensure the repeatability of test process parameters and the reproducibility of test results.

Qinsun Si4000 Xenon Test Chamber Description

● The service life of the lamp: It is recommended to replace 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 the combination of internal and external filters.

The spare parts kit contains two lamps, a number of internal and external filters and other consumables, which are sufficient for the 4000-hour test.

● The Si4000 lamp tube stands upright in the center of the test box, around the upper and lower three-layer rotating sample rack, which can hold 65 samples (sample size is 70x145x3mm), 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.

● Si4000 is a water-cooled xenon lamp aging instrument.

The inner and outer filters form a water jacket while filtering light.

The flow of pure water takes away the huge heat generated by the xenon lamp.

● Pure water is used for lamp cooling, spraying and humidification.

The high purity of water can reduce the deposition of impurities on the filter and prevent the influence of radiation intensity;

● Spray is to simulate rain; humidification is to use compressed air to spray pure water into mist to control the humidity in the box.

So users need to prepare pure water or pure water generating device.

There is a small pure water tank at the lower left front of the Si4000, and the pure water flowing through the lamp tube flows back to the tank.

After the pure water is lost, the water level drops, and the machine automatically fills in water to replenish; in this tank is also equipped with a snake-shaped cooling tube, Tap water inside, because the pure water absorbs the heat of the lamp tube and the water temperature rises.

When the temperature in the pure water tank exceeds 55℃, the tap water in the serpentine tube starts to flow to cool the pure water, keeping the pure water cool The efficiency of the lamp.

The temperature of the tap water is recommended to be below 20°C.

If the user considers the cost and temperature of tap water, it is recommended to equip an ice water machine for recycling.

When the temperature in the pure water tank exceeds 65°C, Si4000 will automatically shut down for protection.

● Rotating drum sample holder and uniformity of irradiation intensity and blackboard temperature: Si4000 rotating drum sample holder is designed to place the sample vertically on the rotating rack in the center of the instrument.

The rotating rack consists of a cylindrical single-layer sample display structure The sample is rotated on the drum frame around the light source at a speed of 1 circle per minute to obtain a balanced light energy, temperature and humidity.

Since the xenon lamp tube itself will age while working, it will produce some black spots, and the black spots will affect the uniformity of the light.

The drum sample holder rotates at a constant speed when working, so that the light from the black spots acts on the entire sample space evenly., It balances this kind of subtle error to the greatest extent.
