本発明は、各種電解装置の電極用素材や各種の触媒用素
材となるカーボンブラック等の撥水性物質の微粉体を水
に濡らす方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of wetting fine powder of a water-repellent substance such as carbon black, which is a material for electrodes of various electrolyzers and a material for various catalysts, with water.
（従来の技術）
従来、カーボンブラックを触媒調整の一工程として水に
濡らすには、水に界面活性剤や塩酸を加え、これをカー
ボンブラックに含浸させている。(Prior Art) Conventionally, in order to wet carbon black with water as a step of catalyst preparation, a surfactant or hydrochloric acid is added to water, and the carbon black is impregnated with this.
またｐＨ測定の際にはカーボンブラックに湯を含浸させ
ることが行われている。Furthermore, when measuring pH, carbon black is impregnated with hot water.
（発明が解決しようとする課題）
ところで、水に界面活性剤や塩酸を加え、これをカーボ
ンブラックに含浸させる方法は、カーボンブラックが水
に濡れた後界面活性剤や塩酸を除去する操作が必要とな
り、甚だ面倒で手間隙がかかる。(Problem to be solved by the invention) By the way, the method of adding a surfactant or hydrochloric acid to water and impregnating carbon black with it requires an operation to remove the surfactant or hydrochloric acid after the carbon black gets wet with water. This is extremely troublesome and time-consuming.
またカーボンブラックに湯を含浸させる方法は、カーボ
ンブラックが撥水性で非常に軽い為、湯の上昇気流によ
り舞い敗ってロスが多いものである。Furthermore, in the method of impregnating carbon black with hot water, since carbon black is water repellent and extremely light, it is blown away by the rising air currents of hot water, resulting in a large amount of loss.
そこで本発明は、水に界面活性剤や塩酸を添加せずに撥

粉体を大気中に飛散せずに水に濡らすことのできる方法
を提供しようとするものである。Therefore, the present invention provides a method that allows fine powder of a water-repellent substance to be wetted with water without adding surfactants or hydrochloric acid to water, and also allows the fine powder to be wetted with water without scattering the fine powder into the atmosphere. This is what we are trying to provide.

とするものである。(Means for Solving the Problems) In order to solve the above problems, the method of wetting the water-repellent material of the present invention with water is to introduce fine powder of the water-repellent material directly into water under strong stirring by vacuuming. It is characterized by being wetted with water.

Add 300 β of water 3 to the top opening of water [2].
The vibrator 4 connected to the /min vacuum line is installed, and the lid 6 installed through the fine powder introducing vibrator 5 is sealed.
The opening of the fine powder introduction pipe 5 is once located in the lower part of the water tank 2. A storage tank 8 containing 5 g of carbon black 7 is made to face the opening at the other end.

０．０１％以下であった。Then, the starter 1 is driven, the water 3 in the water tank 2 is strongly stirred, the water 3 in the water tank 2 is evacuated through the pipe 4 connected to the vacuum line, and 5 g of carbon black 7 in the storage tank 8 is passed through the fine powder introducing vibrator 4 and the water 3 is strongly stirred. When introduced into water 3, the carbon black 7 could be instantly wetted with water 3, and the loss was less than 0.01%.

いものである。(Effects of the Invention) As can be seen from the above explanation, the method of wetting the water-repellent substance with water according to the present invention is to introduce fine powder of the water-repellent substance directly into water by vacuuming it while stirring vigorously, and to form water bubbles. Since it is wrapped in water and instantly wetted with water, it does not scatter into the atmosphere and there is extremely little loss.Also, there is no need to add surfactants or hydrochloric acid to the water, so the fine powder of the water-repellent substance is absorbed into the water. It is extremely easy to work with, as there is no need to remove the additives after the product has been wetted with water.
