Description of the Related Art Nondestructive inspection is employed as a method for inspecting materials, especially metallic materials, for defects such as welding defects, polishing cracks, burn cracks and the like. One of the non-destructive inspection methods is a penetrating inspection method. This method is performed according to the process sequence shown in FIG. This will be described with reference to FIG. In FIG. 3, (a) a permeating liquid P is applied to the surface T0 of the material T to be inspected in a permeating liquid applying step. Then, the applied penetrant P penetrates to the wound W, if any. Next, in step (b), the penetrating liquid P applied to the surface T0 is wiped off from the surface T0 in the wiping and removing step, and in step (c), an alcohol mixed with fine powder M such as black ink called a developer D is applied in the developing liquid applying step. . Then the alcohol evaporates immediately,
The fine powder M remains in a thin layer on the surface.

料を使用した染色液が使用される。[0003] Therefore, in (d) the fine powder M of the developer D in the flaw confirmation step, the permeation liquid P which has been applied and penetrated into the cracks of the flaw W is sucked out in the above (a) permeation liquid application step. An instruction pattern corresponding to the presence of the flaw W is detected in the developer D, and the presence of the flaw is confirmed. Then, according to this method, even a minute flaw that cannot be visually confirmed can be confirmed. As the permeating solution P, a dyeing solution using a red dye is particularly used.

していた。However, in the penetrant inspection method as described above,
Conventionally, when applying the permeating solution P,
The permeate P contained in a commercial 3.8 liter (L) can is filled with 500 to 1000 milliliters (m
L), and was moistened with a brush for application, and thereby applied to the surface T0 of a predetermined material T to be inspected.

であった。As described above, when applying the permeate, the permeate P contained in a 3.8-liter (L) can, which has been distributed and traded as a conventional product, is taken from 500 to 1000. In the method of dispensing a small volume in a small volume container of milliliter (mL), in order to avoid additional subdivision work and to perform the penetrant testing efficiently, according to experience, the amount should be slightly larger than required. The actual situation was to subdivide and apply to the volume container.

も問題であった。For this reason, at the end of the application of the penetrating liquid, the penetrating liquid is left behind. The remaining permeate is deteriorated in its function, and foreign matter is mixed in when the brush is taken in and out during the coating operation, so that it cannot be returned to the original large can for commerce. Had been discarded.
The disposal increases the test cost of the penetrant inspection, which is economically problematic and also causes environmental pollution.

まう問題があった。In the method of applying a penetrating solution by brushing by subdividing into small-volume containers as described above, both hands are closed by holding a small-volume container containing the penetrating solution or by using a brush for application. In particular, when conducting penetration testing for large-scale equipment, using stepladders or assembling a scaffold to go up to a high place and perform coating work may cause danger-related problems, or may cause imbalance and cause penetration. There was a problem of spilling liquid.

In addition, since the permeate remaining after use is not contaminated and can be stored because it can be used for subsequent penetrant inspection, it does not pollute the surrounding environment due to disposal and is excellent in environmental hygiene. It works.
