800 Xenon lamp weathering test chamber(electrostatic spray)

Simulates the full sunlight spectrum：

The Xenon Lamp Weathering Chamber measures the light resistance of materials by exposing them to ultraviolet (UV), visible, and infrared light. It uses a filtered xenon arc lamp to produce the full sunlight spectrum with maximum matching to sunlight. A properly filtered xenon arc lamp is the best way to test a product’s sensitivity to longer wavelength UV and visible light in direct sunlight or sunlight through glass.

Light fastness testing of interior materials：

Products placed in retail locations, warehouses, or other environments can also experience significant photodegradation due to prolonged exposure to fluorescent, halogen, or other light-emitting lamps. The xenon arc weather test chamber can simulate and reproduce the destructive light produced in such commercial lighting environments, and can accelerate the test process at higher intensity.

Simulated climate environment：

In addition to the photodegradation test, the xenon lamp weather test chamber can also become a weathering test chamber by adding a water spray option to simulate the damage effect of outdoor moisture on materials. Using the water spray function greatly expands the climatic environmental conditions that the device can simulate.

Relative Humidity Control：

The xenon arc test chamber provides relative humidity control, which is important for many humidity-sensitive materials and is required by many test protocols.

The main function:

▶Full spectrum xenon lamp;

▶A variety of filter systems to choose from;

▶Solar eye irradiance control;

▶ Relative humidity control;

▶Blackboard/or test chamber air temperature control system;

▶Test methods that meet the requirements;

▶Irregular shape holder;

▶Replaceable xenon lamps at reasonable prices.

Light source that simulates the full sunlight spectrum：

The device uses a full-spectrum xenon arc lamp to simulate the damaging light waves in sunlight, including UV, visible and infrared light. Depending on the desired effect, the light from a xenon lamp is usually filtered to produce a suitable spectrum, such as the spectrum of direct sunlight, sunlight through glass windows, or the UV spectrum. Each filter produces a different distribution of light energy.

The life of the lamp depends on the irradiance level used, and the life of the lamp is generally about 1500~2000 hours. Lamp replacement is easy and quick. Long-lasting filters ensure that the desired spectrum is maintained.

When you expose the product to direct sunlight outdoors, the time of day that the product experiences maximum light intensity is just a few hours. Even so, the worst exposures only occur during the hottest weeks of the summer. Xenon lamp weather resistance test equipment can speed up your test process, because through program control, the equipment can expose your product to a light environment equivalent to the noon sun in summer 24 hours a day. The exposure experienced was significantly higher than the outdoor exposure in terms of both average light intensity and light hours/day. Thus, it is possible to accelerate the acquisition of test results.

Control of light intensity：

Light irradiance refers to the ratio of light energy impinging on a plane. The equipment must be able to control the irradiance intensity of the light in order to achieve the purpose of accelerating the test and reproducing the test results. Changes in light irradiance affect the rate at which material quality deteriorates, while changes in the wavelength of light waves (such as the energy distribution of the spectrum) simultaneously affect the rate and type of material degradation.

The irradiation of the device is equipped with a light-sensing probe, also known as the sun eye, a high-precision light control system, which can compensate in time for the decline in light energy due to lamp aging or any other changes. The solar eye allows the selection of an appropriate light irradiance during testing, even a light irradiance equivalent to the midday sun in summer. The solar eye can continuously monitor the light irradiance in the irradiation chamber, and can precisely keep the irradiance at the working set value by adjusting the power of the lamp. Due to long-term work, when the irradiance drops below the set value, a new lamp needs to be replaced to ensure the normal irradiance.

Effects of Rain Erosion and Moisture：

Due to frequent erosion from rain, the coating layer of wood, including paints and stains, will experience corresponding erosion. This rain-washing action washes away the anti-degradation coating layer on the surface of the material, thereby exposing the material itself directly to the damaging effects of UV and moisture. The rain shower feature of this unit can reproduce this environmental condition to enhance the relevance of certain paint weathering tests. The spray cycle is fully programmable and can be run with or without a light cycle. In addition to simulating moisture-induced material degradation, it can effectively simulate temperature shocks and rain erosion processes.

The water quality of the water spray circulation system adopts deionized water (solid content is less than 20ppm), with the water level display of the water storage tank, and two nozzles are installed on the top of the studio. Adjustable.

Moisture is also the main factor causing the damage of some materials. The higher the moisture content, the more accelerated the damage to the material. Humidity can affect the degradation of indoor and outdoor products, such as various textiles. This is because the physical stress on the material itself increases as it tries to maintain a moisture balance with the surrounding environment. Therefore, as the humidity range in the atmosphere increases, the overall stress experienced by the material is greater. The negative effect of humidity on the weatherability and colorfastness of materials is widely recognized. The moisture function of this device can simulate the effect of indoor and outdoor moisture on materials.

The heating system of this equipment adopts far-infrared nickel-chromium alloy high-speed heating electric heater; high temperature, humidity, and illumination are completely independent systems (without interfering with each other); temperature control output power is calculated by microcomputer to achieve high-precision and high-efficiency electricity consumption benefit.
