Solar backsheet electrolysis water vapor permeability tester is an instrument used to measure the water vapor permeability performance of solar backsheet materials. Here's a closer look at the instrument:
1. The test principle of the solar backsheet electrolysis water vapor permeability tester
The instrument adopts the principle of electrolysis test. The instrument clamps the sample to be tested between the dry and wet chambers at a constant temperature, and there is a certain humidity difference on both sides of the sample. Due to the presence of a humidity gradient, water vapor diffuses from a high humidity cavity to a low humidity cavity. In a low-humidity chamber, water vapor is carried by the carrier gas to the cell, where an electrolytic reaction takes place to generate a current signal. Through the analysis and calculation of the current signal, the water vapor permeability and moisture permeability coefficient of the sample are obtained.
2. Characteristics of solar backsheet electrolysis water vapor permeability tester
1. Advanced electrolytic testing technology: the new electrolytic moisture analysis sensor is used to accurately measure the water vapor permeability, and the results are reliable.
2. High-precision temperature control system: using international advanced temperature control technology, space three-dimensional constant temperature technology, program stepping mode can freely control the temperature rise and fall, and the temperature control accuracy is accurate to 0.2°C.
3. Dual-airflow humidity control: high humidity control accuracy and stable humidity to ensure the accuracy of test results.
4. Touch screen operation: The host is equipped with a 240,000 true color touch screen, which can set various parameters, display test curves and reports.
3. Test steps
1. Use a special sample cutter to cut 3 pieces of 108 mm × 108 mm samples from the surface of the solar backsheet.
2. Clamp the 3 samples on the 3 test chambers of the instrument and tighten the test chambers.
3. Set the sample thickness, test temperature, test humidity and other parameter information.
4. Start the test, the instrument will automatically record the data and calculate the water vapor permeability and moisture permeability coefficient.
Fourth, the field of application
Solar backsheet electrolysis water vapor permeability tester is widely used in the quality control and technology research and development of solar backsheet materials. By testing the water vapor permeability of the solar backsheet material, its moisture-proof and waterproof properties can be evaluated, which provides an important guarantee for the long-term stable operation of the solar panel.
To sum up, the solar backsheet electrolysis water vapor permeability tester is a powerful and easy-to-operate instrument with the characteristics of high precision and high stability. The instrument has a wide range of application prospects in the field of quality control and technology research and development of solar backsheet materials.
