Yanzhi Acetic acid test box Model: CHT-YW 400

Photovoltaic applications

1. To evaluate the acid and corrosion properties of photovoltaic cells.

2. Optimize the production process and materials of the battery piece.

3. Quality testing and screening.

4. This test box is one of the artificial climate corrosion test box, which is the corrosion test box simulating the atmospheric corrosion environment. It is suitable for the corrosion test of various metal materials and paint coatings. Reliable acceleration simulates the corrosion effect of the specimen in the environment of infiltration of brine and alternating dry and wet conditions, so as to assess the adaptability and reliability of products, product components and raw materials in the climate environment. Suitable for cells of cells 166-230.

1) Easy to operate: there is a storage tank outside the test tank, there is a skateboard at the bottom of the storage tank, the top of the slide for the storage tank, and there are splints on both sides of the storage tank;

2) operator protection: the back of the top cover is equipped with a frame, the exhaust device is installed inside the frame, the exhaust device is equipped with a drawing plate, and the push plate on the top of the drawing plate. After the test, push the push plate to pull the drawing plate in the opposite direction, and then start the exhaust device, which can first discharge the gas inside the test box, so as to avoid inhaling a large number of possible harmful gases when opening the top cover;

3) High accuracy: it can simulate the acetic acid environment, temperature, humidity and other conditions, and set the test time and analyze the test data, helping to improve the accuracy of the test, so as to better evaluate the durability of photovoltaic cells in the acetic acid environment.

Laboratory temperature range

RT + 15℃ ~150℃ (setting)
Average heating rate1℃ / min
Temperature fluctuation degree± 0.5℃
Temperature uniformity1.5℃
Sealattenuation<0.3%
Studio size400 * 400 * 400mm (compatible: 166-230 battery; product separated from test solution, suspended with anti-climbing fluid)
Specification and modelPERC + TOPCON compatible, flower rack compatible with all sizes
Air supply modethe lower air and the upper return air, to ensure the uniformity of air circulation, the battery air heat evenly (the flower rack is very important, the wind speed should be adjustable), to ensure the consistency of acetic acid concentration in the box, the wind speed can be adjustable
