側と外槽枠とで外槽を密閉状とする試験装置が使用され
ていた。When there is a temperature difference on both sides of a paint film, a heat flow occurs from the high temperature side to the low temperature side, and this heat flow causes water vapor to move from the high temperature side to the low temperature side, causing paint film blistering. Conventionally,
In order to perform a coating film blistering test by applying a temperature gradient, the inner tank was sandwiched between test pieces from both sides, the inner tank was sealed, and outer tank frames were placed outside of both test pieces. A test device was used in which the outer tank was sealed with one outer side and an outer tank frame.

れている。In the figure, reference numeral 1 denotes four paint film test pieces, each of which is attached to a rectangular side wall to form an inner tank 2. The test piece 1 was held between a presser plate 11 via a rubber gasket 10a, with the test coating 1a on the outside and the rust-preventing coating 1b on the inside. 1C indicates the material of the coating film test piece. Test piece 1
A transparent glass plate 12 is arranged on the outside of the glass plate 12 with each end parting apart from the spacer 3, and is held between the press plate 11 via a rubber gasket 10t+, and a transparent acrylic plate 16 is attached to the outside of the glass plate 12. The outer tank 6 is formed by tightening the nut 15 of the stud 14. 4 is an outer tank test liquid inlet pipe, and 5 is the same outlet pipe, which penetrate the acrylic plate 13 and the glass plate 12 and communicate with the outer tank 6. 7 is an inner tank test liquid circulation pump unit, which communicates with the inner tank 2 via an inner tank test liquid circulation hose 7a, and 8 is an inner tank test liquid cooling device, which connects the inner tank through a cooling water circulation hose 8a. It communicates with a cooling pipe 16 installed inside 2. Reference numeral 9 designates 22 outer tank test liquid circulation pumps connected to the outer tank test liquid inlet pipe 4 and outlet pipe 5 via the outer tank test liquid circulation hose 9a.
