Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a composition having a discharge property.

[0002]

2. Description of the Related Art Conventionally, when two kinds of metals are immersed in water in a state of being close to each other, only one of the metals is ionized and precipitated due to a difference in ionization tendency of each metal.
It is known that a discharge occurs at that time.

However, merely bringing two kinds of metals close to each other causes only a slight discharge, and the electromotive force is about several millivolts, and water is electrolyzed using the electromotive force. I couldn't do anything.

For example, even if an aluminum plate and a copper plate whose surfaces are polished in water are stacked, no air bubbles are generated at all, and the aluminum plate and the copper plate whose surfaces are polished in an aqueous solution of sodium chloride instead of water are used. , Only a few bubbles of about 0.5 mm were generated in one hour.

[0005] Even when the copper wire wound with aluminum foil was left in distilled water, no change was observed.

[0006]

As described above, theoretically, when two kinds of metals are immersed in water in the state of being close to each other, only one of the metals is ionized and precipitated due to the difference in ionization tendency of each metal. However, even if it is known that a discharge occurs at that time, it is difficult to make a practical discharge possible only by bringing two kinds of metals close to each other.

Accordingly, the present invention has been made in view of how to produce a practically dischargeable composition using two kinds of metals having different ionization tendencies.

[0008]

According to the present invention, two kinds of metal powders having different ionization tendencies are formed by using an alkali as a binder.

As the binder, any of quick lime, slaked lime, cement and gypsum is used.

[0010] Further, pressure molding is performed at a high pressure in a substantially vacuum atmosphere.

Further, the molded composition is impregnated in a liquid containing metal ions to adsorb the metal ions in the liquid.

Further, the molded composition is impregnated in a liquid to supply oxygen into the liquid.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The composition having a discharge property according to the present invention is obtained by pulverizing two kinds of metals having different ionization tendencies into powders and applying a high pressure in a substantially vacuum atmosphere using an alkaline material as a binder. It was pressed.

The two types of metals having different ionization tendencies include:
For example, potassium, calcium, sodium, magnesium, aluminum, zinc, iron, nickel, tin, lead, copper, silver,
Two kinds of metals (aluminum, copper, etc.) selected from platinum and gold can be used. In particular, when metal waste such as aluminum dross is used, the metal waste can be effectively reused.

Examples of the alkaline binder include:
1 selected from quicklime, slaked lime, cement, plaster, etc.
Species or a mixture of two or more can be used.

As an apparatus for press-forming at a high pressure in a substantially vacuum atmosphere, a vacuum forming apparatus disclosed in Japanese Patent No. 2931258 can be used.

The molded article thus obtained is a practically usable composition for performing electric discharge. By immersing such a composition in water, water can be electrolyzed, and water is used as a raw material. To generate hydrogen and oxygen.

This is because the powdered metal particles having different ionization tendencies are densely packed inside the compact, and the metal particles are very close to each other via the binder. It is considered that electric discharge occurs between the electrodes, and further, the alkaline binder acts as a catalyst to promote electrolysis of water.

Therefore, oxygen can be supplied to the liquid by impregnating the molded body with a liquid such as water, an aqueous solution, or seawater.

When the compact is impregnated in a liquid containing metal ions, the metal ions in the liquid can be adsorbed.

[0021]

EXAMPLES Examples of the present invention will be specifically described below.

Aluminum powder (particle size: about 10 μm)
2 g, 11 g of copper powder (particle size: about 30 μm), 80 g of slaked lime (particle size: 60 to 100 μm), stone powder (particle size: 60 to 100 μm)
μm), 9 g of water was added thereto, and the mixture was press-formed at 1500 kg / cm ² using a vacuum forming machine.

The molded body has a size of 150 mm in length and 150 mm in width.
mm, the thickness was 4.7 mm, and the specific gravity was 2.846 g / cc.

This was immersed in a glass cup containing 50 cc of water, and the upper opening of the glass cup was sealed with a plastic bag.

Then, a very large number of bubbles of about 1 mm are continuously and violently generated from the surface of the molded body for about 10 hours, and thereafter, about 0.5 mm for about 10 hours.
Air bubbles of about mm were continuously generated.

Then, 20 hours after the immersion of the molded article, the water level in the glass cup dropped and 1
0 cc of gas was obtained. This gas was confirmed to be an explosive gas that exploded when fire was brought close to it, indicating that it was hydrogen and oxygen obtained by electrolyzing water.

Therefore, when the compact was impregnated in a liquid such as water, an aqueous solution or seawater, oxygen could be supplied to the liquid.

When the compact was impregnated in a liquid containing metal ions, the metal ions in the liquid could be adsorbed. In particular, when the molded article was impregnated in a liquid containing a harmful substance such as heavy metal or heavy metal ion, the harmful substance was adsorbed by the molded article and the liquid could be rendered harmless.

Further, the above compact may be crushed by a granulator to obtain a granular compact, or the granular compact may be formed into a massive compact using an inorganic or organic binder.
It was confirmed that substantially the same effect was obtained although it was slightly inferior.

The molding method of the molded article in the present embodiment,
The size, shape, metal type, compounding ratio, and the like are merely examples, and the present invention is not limited to such a molded product.

[0031]

The present invention is embodied in the form described above and has the following effects.

That is, in the present invention, a practically usable discharge-forming composition can be formed by molding two kinds of metal powders having different ionization tendencies using an alkali as a binder.

By immersing such a composition in water, water can be electrolyzed, and hydrogen and oxygen can be produced using water as a raw material.

By impregnating the molded body with a liquid such as water, an aqueous solution or seawater, oxygen can be supplied into the liquid.

Further, by impregnating the compact with a liquid containing metal ions, the metal ions in the liquid can be adsorbed. In particular, when a harmful substance such as heavy metal or heavy metal ion is contained in the liquid, the harmful substance can be adsorbed to make the liquid harmless.
