を提供する。That is, the present invention (11 K in the impregnation apparatus, after putting the container containing the object to be impregnated, reduce the pressure (vacuum state) inside the apparatus and the object to be impregnated.
Then, the impregnating liquid is injected into the header connected to the opening of the container of the object to be impregnated, a part of the impregnating liquid is retained in the header, and the inside of the apparatus is pressurized (from a vacuum state to atmospheric pressure or higher). ) A method for impregnating an object to be impregnated with an impregnating liquid (2) (b) a depressurized/pressurized tank having a vent hole for injecting the impregnating liquid, and a liquid injection port for injecting the impregnating liquid; To provide a device consisting of an internal jig mainly consisting of a header that can be held outside the container.
以下に本発明の方法における操作方法を説明すると以下
のとおりである。The operating method in the method of the present invention will be explained below.
１）まず被含浸体およびその容器（ワーク）へヘッダー
例えば筒状容器を装着する。これを減圧・加圧槽内に入
れ槽内を排気し、ワーク内をも減圧（真空）状態とする
。1) First, a header, such as a cylindrical container, is attached to the object to be impregnated and its container (work). This is placed in a pressure reducing/pressurizing tank and the tank is evacuated to create a reduced pressure (vacuum) state inside the workpiece.
２）つぎに含浸液を所定量、注入口より前記ヘッダーを
経由してヘッダー自身及びワーク内に注入する。このと
き含浸液面はヘッダー内に保持され、液封が保たれなけ
ればならない。2) Next, a predetermined amount of impregnating liquid is injected from the injection port through the header and into the header itself and the workpiece. At this time, the level of the impregnating liquid must be maintained within the header to maintain a liquid seal.
３〕 ついで真空バルブを閉じ、Ｎ，、エア等圧力ガス

内な加圧状態に維持する。3] Next, close the vacuum valve, and introduce a pressure gas (1 to 3 k1/d-G) of N, air, etc. from the supply port to maintain the pressurized state in the tank.
この時，この外圧により含浸液の被含浸体への浸透速度
は加速される。At this time, the rate of penetration of the impregnating liquid into the object to be impregnated is accelerated by this external pressure.
被含浸体は、内部が真空状態であり、その容器及びヘッ
ダーにより、液面を高く維持される為、液封状態となる
。そこで、槽内な加圧すれば、その差圧により速く含浸
ができる。The object to be impregnated is in a vacuum state inside, and the liquid level is maintained high by the container and header, so it is in a liquid-sealed state. Therefore, if the pressure inside the tank is increased, impregnation can be carried out faster due to the differential pressure.
４）含浸液が被含浸体に全部吸収されるに必要な時間経
過後槽内をベントで大気圧にすると共ｋ。4) After the time required for the impregnating liquid to be completely absorbed by the object to be impregnated, the inside of the tank is vented to atmospheric pressure.
ヘッダーをワークより取りはずし、新しいワークを取付

内部は真空状態になり、電解液注入後、周囲を大気圧以
上に加圧することでセ、ル内部と差圧が生じ、その差圧
を駆動力として電解液は、セル内部に浸透し含浸が進行
する。To describe the operation of the present invention in more detail using the example of a battery, by evacuating the battery can, the inside of the cell in the battery can becomes a vacuum state, and after the electrolyte is injected, the surrounding area is pressurized to above atmospheric pressure. This creates a pressure difference between the cell and the inside of the cell, and the electrolyte penetrates into the cell using this pressure difference as a driving force, and impregnation progresses.

ーが接続されていることによシ、電解液面は含浸が終了
するまで、セルよシ高い位置を保たれ、セル内部には電
解液のみ充てんされる。At this time, if the cell comes into contact with the surrounding pressurized gas, gas will seep into the cell, but because the header is connected to the top of the battery can, the electrolyte surface is completely impregnated. Until then, the cell is kept at a higher position than the cell, and only electrolyte is filled inside the cell.

３ Ｋ４７ｃｍ２− Ｇが適当である。In the conventional method, the inside of the cell and the surroundings are at the same atmospheric pressure, but in the present invention, the IKg/cnr2 between the inside of the cell and the surroundings is
By utilizing a pressure difference of -0 or more, it has become possible to significantly accelerate the electrolyte absorption rate of the cell. In this case, the degree of vacuum inside the cell is preferably 10 toir or less, and the pressurization pressure is 1 to 1.
3K47cm2-G is suitable.
なお、電池以外の場合でも、被含浸体の形状構造と含浸
液の物性とによって、真空度と加圧圧力との組み合わせ

適宜選択され得る。Note that even in cases other than batteries, the combination of the degree of vacuum and the pressurizing pressure may be selected within the above range or as appropriate, depending on the shape and structure of the object to be impregnated and the physical properties of the impregnating liquid, as long as the object of the present invention is achieved.

Finish impregnation.
含浸終了後、パルプ４を開き、減圧・加圧槽５内を大気
