Water requirements for water cooled xenon lamp aging tester

The water-cooled xenon lamp aging test machine is a domestic experimental equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd., model Si4000, which can be compared with ATLAS Ci4000, and is used for testing solar photovoltaic, plastics, paints, packaging, automotive materials, textiles Industry understands the weather resistance of materials such as geotextiles, pigments, stabilizers and additives.

Main parameters:

1. Light source: 6500W water-cooled xenon lamp tube;

2. Spectrum range : full spectrum sunlight;

3. Irradiance control points: 340nm, 420nm, 300-400nm, 400-750nm, etc. can be selected;

4. The number of specimen racks that can be installed: 65, a total of 3 layers;

5. Total exposure area : 6500 cm2.

In addition, the requirements for using the water-cooled xenon lamp aging tester are much higher than those air-cooled xenon lamp weather resistance test chamber, and it needs pure water equipment, and the air-cooled xenon lamp weather resistance test chamber can be sprayed with tap water. The water-cooled xenon lamp aging machine requires high water purity because the cooling lamp mainly uses water from the purifier. If the water quality is not good, scale will be generated, which will affect the irradiation of the lamp.

1. The cooling water of the lamp should use demineralized water, and tap water should not be used without permission. If the water is too high, the lamp will be damaged when the lamp is triggered. The inlet temperatureSecondary water temperature should be less than 35°C, because xenon lamp life will be shortened if the water temperature is too high, so a closed cold water system should be used when operating. the use of circulating water and filtration system to ensure secondary pollution of water quality due to cooling.

2. The spray and humidification water in the water-cooled xenonLamp aging tester should be distilled water. If the general tap water sample is used, there will be a white substance on the surface of the sample. If the purpose of the irradiation is not achieved, this substance is water. The impurity in the product evaporates to form a crystal called calcium magnesium, so this requires the use of distilled water to ensure consistent irradiation and accurate testing.

As a company integrating R&D, manufacturing, sales, training andservice, Shanghai Fanbiao Textile Testing Technology Co., Ltd. is committed to providing more test instruments to the market, long-term supply of textile, leather, combustion test instruments, automotive interior materials, environmental weather aging, masks and protective clothing, etc., can also accept non-standard customization. Before purchase, we can carry out targeted tests according to customer requirements to ensure that the instruments purchased are suitable.
