  Embodiments of the method for producing a metal carbon tightly bonded body and the metal carbon tightly bonded body of the present invention will be described below. The embodiment of the present invention shows the most preferable mode of the present invention, and the present invention is not limited to this.

[First Embodiment]
As shown in FIG. 1, the method for producing a metal-carbon tightly bonded body according to the first embodiment includes a carbon material water-soluble paste mixing step A1, a mixed metal material mixing step B1, and a kneading step C1. And a drying step D1 to produce a metal-carbon tightly bonded body E1.

(Carbon material water-soluble paste mixing step A1)
In this carbon material water-soluble paste mixing step A1, at least a powdery or granular carbon material and at least a powdery water-soluble paste are blended so that the carbon material is larger than the water-soluble paste in a volume ratio. Mix. For example, the carbon material and the water-soluble paste have a volume ratio of 6 to 9: 4 to 1, preferably 7 to 8: 3 to 2, and the water-soluble paste functions as an adhesive. Be less than carbon materials. The carbon material may be powdery or granular, or may be a mixture of powdery and granular.

  As carbon material, graphite graphite such as artificial graphite or natural graphite, coke of dry distillation such as coal and pitch, charcoal, bamboo charcoal, bagasse charcoal, coconut shell charcoal, fir shell charcoal, etc. They are preferably fine powders, powders and granules having a carbon purity of 80% or more. Distillates are rich in mineral components. In addition, the dry distillate is porous, and the pores can provide a breeding place for microorganisms and a place for absorbing, adsorbing and joining dissolved substances. Moreover, plant dry-distilled coal can add charcoal ash as a fertilizer effect agent. Further, as the carbon material is made finer, the force (van der Worth force) attracting each other to the metal material is stronger and the adhesion force is increased.

  Examples of the water-soluble paste powder include starch paste powder and polyvinyl alcohol (PVA) powder. Examples of the starch paste powder include a paste powder produced by boiling wheat flour in water, a powder of a dextrin component obtained by saccharifying potato starch, and functions as a water-soluble adhesive.

(Mixed metal material mixing step B1)
In this mixed metal material mixing step B1, a mixture of a carbon material and a water-soluble paste and at least a granular or flaky metal material are blended so that the mixture is larger than the metal material in a volume ratio. And mix. The metal material may be granular, may be in the form of a piece, or may be a mixture of a granular material and a granular material.

  Examples of the metal material include magnesium (Mg), copper (Cu), iron (Fe), zinc (Zn), silver (Ag), etc. A metal that is as close to a single metal as possible is good. Further, when a reduced metal is used, the efficiency of metal oxidation is greatly improved and the generation efficiency of the metal ions is also improved. Also, atomized metal particles obtained by applying vibration to metal particles in the atmosphere, modifying the surface of the particles by contact between metal particles, and then performing hot forming processing can be used.

  For example, as iron materials, reduced iron particles and iron pieces, cutting scraps of steel iron, that is, Daraiko of chips generated by processing can be used. In particular, the iron material is required to have no oil or the like on its surface, no coating on the surface for the purpose of protection, or the absence of printing ink. For example, an iron thin plate or an empty steel can can be obtained by incinerating a surface coating or printing ink and crushing it. When such a shredded product is used as an iron material, the iron material is baked and left in the atmosphere, so that it is oxidized and rust is easily generated.

(Kneading process C1)
The kneading step C1 is performed by adding water containing salt to the mixture in which the metal material is mixed, so that the carbon material of the mixture adheres to the metal material in a large amount due to the adhesive force of the water-soluble paste. Knead and harden into a bun. Water is an additive of salt, such as seawater, salt-added water, salt-humidified air, etc. The supply amount of salt-containing water is a metal material and a carbon material is a water-soluble paste. It is an amount that can be kneaded and hardened so that it adheres due to the adhesive force of. As described above, the water uses water containing a salinity having a low salinity concentration up to the level of seawater, and the salinity dissolves in the water and serves as an electrolyte. In this way, the first stage is completed by kneading and solidifying to form aggregates.

  And then, in this kneading step C1, as a second stage, at least a binder of clay powder, bentonite powder, gypsum powder, or plaster powder is mixed with the kneaded aggregate and does not contain salt. A nodule is formed by combining a plurality of aggregates that have been kneaded and hardened by adding water and then kneaded. The supply amount of salt-free water is such an amount that a plurality of kneaded aggregates can be combined with a binder, and in this way, a plurality of kneaded aggregates are combined in the second stage. Finish forming a baby boom.

  In this second stage, an organic acid granule may be added to the clay powder, bentonite powder, gypsum powder, or plaster powder, and further fertilizer effect chemicals such as chemical substances that become fertilizers. May be added, but the amount should not lose the main adhesion function. Moreover, clay powder or bentonite powder to which a fertilizing effect agent is added can be used. By adding an organic acid powder, a metal ion and a chelate complex can be formed, and by adding a fertilizer powder, nutrients for growing plants can be supplied.

  Examples of organic acids include carboxylic acids and hydroxy acids, as well as fulvic acid, succinic acid, malic acid, tartaric acid, citric acid, and ethylenediaminetetraacetic acid (EDTA). That is, any organic acid that can be a chelating agent can be used. . There are many types of carboxylic acids and hydroxy acids having carboxyl groups (—COOH) as typical chelating agents. Among them, fulvic acid, succinic acid, malic acid are particularly commonly used organic acids. Tartaric acid, citric acid, ethylenediaminetetraacetic acid (EDTA), etc. are versatile. By using them easily, it is possible to produce a chelate compound for a metal used as an element for a trace element or other polymerization catalyst.

  It is well known that fulvic acid is made from natural humic substances, and iron chelating compound called fulvic acid iron is supplied to natural creatures and plants as an essential mineral. Succinic acid, malic acid, tartaric acid, etc. are organic acids used as food additives and ingredients, and citric acid is contained in large amounts in fermented foods such as moromi, citrus fruits and dried plums, and is an important and useful food for the living body. Organic acids used as additive contents can be obtained at low cost. This also makes it easy to make iron citrate. Ethylenediaminetetraacetic acid (EDTA) is widely used as a chelating agent because of its versatility. A chelate compound is easily produced without requiring an industrial process.

(Drying process D1)
In this drying step D1, the kneaded aggregate or nodule is dried to remove moisture and solidify. In this drying, the kneaded lumps or lumps are left in the atmosphere or solidified by heat curing.

(Metal-carbon tight junction E1)
As shown in FIG. 2, the metal-carbon tightly bonded body E1 includes at least a powdery or granular carbon material and a powdery water-soluble paste so that the carbon material is larger than the water-soluble paste in a volume ratio. Mix and mix, mix at least granular or flake metal material, stir while adding water containing salt, and attach carbon material 2 to metal material 1 in large quantities by the adhesive strength of water-soluble paste 3 The kneaded particles 10 are dried and solidified by kneading and solidifying to form the aggregates 10. The aggregate 10 has a large amount of carbon material 2 attached to the metal material 1 and can elute metal ions from the metal material 1 into the liquid, and can be mixed with soil such as rice fields or fields, or buried underground. Even if it is mixed with Yasetsutsu Sediment or put into seawater or freshwater or used after installation, the adhesion between the metal material 1 and the carbon material 2 is maintained for a long time by the adhesive strength of the water-soluble paste 3. It is possible to efficiently generate and maintain metal ions and maintain the state of the aggregate 10.

  Further, at least a binder of clay powder, bentonite powder, gypsum powder, or plaster powder is mixed with the kneaded and kneaded aggregate, kneaded by adding water containing no salt, kneaded and kneaded. By forming a nodule 20 in which a plurality of materials are combined with the binding material 4, it is installed on the bottom of the sea, the bottom of a river, the bottom of a dam, and is used as a part of a structure that is always in the water or pasted. It is also possible to do. In addition, the nodule 20 is a combination of a plurality of nodules 10 and gradually deteriorates from the surface of the nodule over time. The nodules 10 are sequentially exposed, and the metal material 1 and the carbon material 2 are used for a long time. Thus, metal ions can be eluted from the metal material 1 into the liquid. The baby boom 20 is used as a product having a predetermined shape, but may be crushed.

  As described above, the metal-carbon tightly bonded body E1 may be a kneaded nodule 10 or a nodule 20 in which a plurality of kneaded nodules 10 are combined, and the metal material 1 and the carbon material 2 can be easily and tightly bonded. The body can be manufactured.

By using this metal-carbon tightly bonded body E1 as a nodule 10 or a nodule 20, the metal material side of the negative electrode negative (low electronegativity) due to the difference in electronegativity between the metal material and the carbon material in the liquid. Electron (e) flows from the positive electrode positive (high electronegativity) carbon material to the particle side. By losing electrons (e) from the metal material due to such a potential difference battery phenomenon, metal ions can be eluted into the liquid. In particular, when the metal carbon tightly bonded body E1 of the nodule 10 or the nodule 20 is placed in the liquid, the salt used for adhesion can be dissolved in the liquid and serve to promote electrolysis. This metal material has a metal ionization tendency, the electronegativity is lower than the electronegativity 2.5 of carbon, and the difference is at least 0.3 or more. Can be eluted.

  That is, by forming the metal-carbon tightly bonded body E1 as a nodule 10 or a nodule 20, the electronegativity can be obtained even in a solution in which dissolved oxygen or a chemical substance that promotes oxidation is not dissolved or in a moisture-moisture enclosure. The metal material can be oxidized and metal ions can be eluted by the potential difference battery phenomenon due to the difference.

  In addition, the metal material 1 and the carbon material 2 are joined together in water by kneading and solidifying the metal material 1 so that the carbon material 2 adheres to the metal material 1 in a large amount by the adhesive force of the water-soluble paste 3 and drying and solidifying. Can be prevented from being separated due to the adhesive force of the adhesive paste 3, the adhesion between the metal material 1 and the carbon material 2 can be maintained for a long time, and metal ions can be efficiently generated and maintained, and the state of the aggregate It is possible to maintain.

  In this way, metal ions can be eluted from the metal material by the potentiometric battery phenomenon due to the difference in electronegativity in the liquid and moisture / moisture surroundings, for example, copper ions have a bactericidal action, and silver and the like. Naturally, ions can be sterilized.

  In particular, when divalent iron ions are supplied and bound to carbon dioxide absorbed and dissolved by water, iron carbonate is immobilized. Similarly to this bond, an artificial chemical substance that is excessively dissolved is also bonded and immobilized with a divalent iron ion, so that the dissolved amount of the artificial chemical substance can be reduced. In addition, divalent iron ions are important minerals for underwater creatures, animals and plants, and by supplying divalent iron ions, mineral iron that is lacking in water can be replenished.

[Example]
Powdered graphite graphite is used as the carbon material, and the graphite graphite and starch paste powder are blended and mixed at a volume ratio of about 8: 2, and the iron pieces reduced as a metal material are mixed into this mixture. Were added and mixed at a volume ratio of about 6: 4.

  To this mixture of iron pieces, gradually add water containing less salt than the salt content of seawater, and knead the whole surface of the iron pieces so that graphite graphite adheres from starch paste. Water addition was stopped when growing.

  Then, the aggregate was dried, and the entire surface of the iron piece was coated with graphite graphite thickly by the adhesive force of starch paste, and fixed and irregular aggregates were produced.

  Thus, when iron pieces and graphite graphite are mixed, graphite graphite uniformly adheres to the surface of the iron pieces by the force (van der Worth force) that attracts the iron pieces and graphite graphite.

  If the graphite piece is attached to the surface of this iron piece and left in a 100% humidity atmosphere containing salt or sprayed with water containing salt to leave it with humidity, the difference in electronegativity, that is, the potential difference. This oxidizes the surface of the iron piece and generates rust. This rust grows and becomes entangled with graphite graphite adhering to the surface to become a fixed aggregate, but the graphite graphite is thickly coated by the adhesive strength of starch paste, and fixed amorphous and irregular aggregates are fixed. Could be manufactured.

  In addition, the surface of the iron piece is entangled with graphite graphite and aggregates in a fixed state are gathered together to form a certain large shape lump, but the kneaded aggregate has at least clay powder or bentonite powder, Alternatively, a gypsum powder or a plaster powder binder was mixed, and water containing no salt was added, kneaded and solidified, and a nodule obtained by binding a plurality of aggregates with a binder could be obtained.

  In particular, even metal materials that generate little rust and metal materials that form a hard, passive film on the surface of the metal material can adhere a large amount of carbon material to the surface of the metal material due to the adhesive force of starch paste, and have adhesive strength. I was able to.

  When using this nodule or nodule, for example, the nodule or nodule may be put into seawater, freshwater or other liquids as it is, or put in a water-permeable bag or container without opening. May be kept.

  For example, if the carbon material particles have countless pores such as dry-distilled plant charcoal, or if it is a porous material that has absorptivity, water absorption, and impurity adsorption properties, It absorbs impurities and works to purify the liquid, and at the same time, its porosity also serves as a place for microbial growth. Furthermore, the used bags and containers are useful as part of the soil if the aggregates or nodules of the contents are taken out and mixed with the soil.

Form the combined baby boom and finish.

  In this second stage, as in the first embodiment, an organic acid granule may be added to the clay powder, bentonite powder, gypsum powder, or plaster powder, and it becomes a fertilizer. Powders of fertilizing effect agents such as chemical substances may be added, but the amount should not lose the main adhesion function.
