Embodiment 1
[0028] Example 1 , glass coating and coating process to reduce loss of platinum-rhodium alloy bushing plate
[0029] Preparation of sol: Weigh glass chemical components and white Suzhou soil in a mass ratio of 15:1, mix and stir with distilled water and absolute ethanol, stir the solution until transparent, take it out after 6 hours in a water bath at 35°C, store at room temperature, and wait for use . The weighed amount of glass chemical components is shown in Table 1:

[0032] Put the coating sample into a self-made resistance furnace for drying. The drying mechanism is: 3°C...
Embodiment 2
[0036] Example 2 , Weigh the glass chemical components and white Suzhou soil according to the mass ratio of 13:1, weigh the glass chemical components according to Table 1, and the experiment numbers are 7, 8, 9, 10, 11, 12. The specific implementation method is the same as that of Example 1. After working for one year, the bushing was disassembled and weighed. The specific results are shown in Table 3.
