The reason why high purity water should be used for spray samples in the aging test of water-cooled

2022-12-29

The equipment used in the water-cooled xenon lamp aging test is a water-cooled xenon lamp aging test machine, most of which are ATLAS Ci4000 xenon lamp aging machines, which are relatively expensive. Today, our company can Shanghai QINSUN Precision Electromechanical Technology Co., Ltd. independently develop and produce domestic experimental equipment, which can be compared with ATLAS Ci4000, which is cost-effective. Welcome customers who need to inquire.

The water-cooled xenon lamp aging tester is used to test the weather resistance of materials such as solar photovoltaic, plastics, paint, packaging, automotive materials and textile industries, including geotextiles, pigments, stabilizers and additives.

Applicable Standards:

AATCCTM16.3-2003, TM16E-1998, TM169, ASTMC1442, D4459, C1501, D4798 8427, 842, 16259, ISO105-B02, 105-B04, 105-B06, 105-B10, 11341, 4892-1, 4892-2, etc.

Our research and development technical engineer said that most people think that pure water The purpose of spraying the sample is to prevent corrosion in the instrument, but that is not the main reason. The main reason is that ultrapure water can guarantee clean test conditions and test reproducibility.

In addition, if there is no water distillation or ionization in combination with reverse osmosis and 0.2 μg/gg/g hydrosolid silicon, the surface of the sample will be stained, which will lead to inconsistent irradiation and influence the test result. There is no special treatment to remove cations, anions and organic matter during natural exposure. Therefore, the silicon content in the spray

should be less than 1. Usually people use the steam method to obtain pure water.
