Production of electroplated transmittance box for electric heating tubes:

Measurement method:

① Production of swimming penetration rate box:

a. Test plate: Phosphated steel plate, size: (300-350) × one hundred and five × 0.75mm

b. Spacer strip: two hard polyvinyl chloride strips, size: 4 × ten × （300-350）mm

There are two types of widths: 20mm and 38mm

② Place the permeation rate box into the matured electrophoresis tank, so that the bottom edge of the box is 60 ± 5mm away from the tank bottom and 30 ± 2mm away from the electrophoresis tank wall;

③ The distance between the volt box and its corresponding electrode is 155 ± 2mm;

④ Connect the power supply and raise the voltage to the specified voltage within 15 seconds. After electrophoresis for 3 minutes, disconnect the power supply;

⑤ Take out the permeability box, tear off the adhesive tape that fixes both sides of the test board, and take out the spacer strip;

⑥ Rinse the test board with deionized water, and then dry the test board according to the specified drying conditions for the electrophoretic coating;

⑦ Clean the partition strips for reuse.

3) The results indicate that:

Measure the length of the paint film on the inner surface of each test panel, calculate the average length in mm, and the value is the visual transmittance value of the paint.

explain:

① Take the average of two tests for the test results;

② The corresponding voltage must be indicated when recording.

Modern power supply technology is a multidisciplinary interdisciplinary interdisciplinary technology that applies power electronic semiconductor devices, integrates automatic control, computer (microprocessor) technology, and electromagnetic technology. It plays a crucial role in various high-quality, efficient, and highly reliable power supplies and is a specific application of modern power electronics technology.

Currently, power electronics, as the foundation of energy conservation, talent conservation, automation, intelligence, and mechatronics integration, are moving towards high-frequency application technology, modular hardware structure, and green product performance. In the near future, power electronics technology
