間経過後も何も異常が認められなかった。1) About the alkali resistance test Ceramics are generally weak against alkalis (the lithium bromide used as the absorption liquid is alkali, and if the super heat-resistant ceramic paint is weak against alkalis, it cannot be used in absorption refrigerators. 1myn thick 5US304 steel plate (100m
A first sample whose surface was coated with a super heat-resistant ceramic paint (mx 100 mm), and a second sample whose steel plate was coated with a general anti-rust paint,
An experiment was conducted in which the sample was immersed in a 10% NaOH solution for 1000 hours. As a result, part of the second sample began to peel off within several tens of hours, but no abnormality was observed in the first sample even after 1000 hours had passed.

っていることが確認できた。ii) Corrosion resistance test Lithium bromide used as an absorption liquid has properties very similar to common salt, and exhibits corrosivity in the presence of oxygen, although it is not like common salt. Therefore, if the super heat-resistant paint does not have corrosion resistance, the super heat-resistant paint cannot be used on the surface of an absorption refrigerator that comes into contact with the absorption liquid. We added the first sample and the second sample to 3% saline solution at 100%
An experiment was conducted in which the sample was immersed for a certain period of time. As a result, rust was observed in the second sample, but no abnormality was observed in the first sample. Therefore, it was confirmed that the steel material coated with the super heat-resistant ceramic paint (first sample) had strong corrosion resistance.

間維持することができる。Absorption refrigerators such as those described above have higher alkali resistance and corrosion resistance than those coated with general anti-corrosion paint, and are designed to minimize corrosion of steel materials and the generation of hydrogen gas caused by this corrosion. Since the pressure can be reduced, the number of times of air extraction can be minimized and a good vacuum state can be maintained for a long time.
