By further including the wire placement step, a magnetic field perpendicular to the surface on which the mineral-containing water is sprayed can be generated. The conductor arrangement process will be described later.

[Contact process]
The contacting step is a step of bringing water into contact with a ceramic containing a natural ore containing an alkali metal and / or an alkaline earth metal. By the contacting step, mineral-containing water containing an ionized alkali metal and / or an ionized alkaline earth metal to be sprayed in the spraying step described later can be obtained.

By bringing the ceramic containing the natural ore into contact with water, the alkali metal and / or the alkaline earth metal contained in the natural ore can be eluted into the water. Alkali metals and alkaline earth metals have a higher ionization tendency than hydrogen. Therefore, the water in contact with the ceramic can be mineral-containing water containing ionized alkali metals and / or ionized alkaline earth metals.

(Natural ore)
The natural ore contained in the ceramic is not particularly limited as long as it contains an alkali metal and / or an alkaline earth metal.

The natural ore preferably contains ⁴⁰ K, which is an isotope of potassium, ^{and / or 87} Rb, which is an isotope of rubidium. As a result, the mineral-containing water can be made into mineral-containing water containing ⁴⁰ K and / or ⁸⁷ Rb and capable of releasing high-energy particles.

The natural ore contained in the ceramic is not particularly limited, and may be, for example, a natural ore containing one or more of the minerals exemplified by feldspar, calcite, dolomite, and zeolite.

The natural ore preferably contains feldspars exemplified by alkaline feldspars and plagioclase. Feldspar is a tectate mineral with a three-dimensional structure that is mainly composed of aluminosilicates such as alkali metals and / or alkaline earth metals. Therefore, the inclusion of feldspar in the natural ore can result in a ceramic that further contains alkali metals and / or alkaline earth metals.

Among the feldspars, the natural ore preferably contains orthoclase, sanidine feldspar, microcline, and alkaline feldspar exemplified by microcline. Alkaline feldspar is a feldspar rich in potassium and / or sodium. Therefore, it can be expected that the natural ore contains alkaline feldspar to make a ceramic containing more potassium. By containing more potassium, it can be expected that the ceramic will contain more ^{potassium 40} K, which is an isotope of potassium.

The natural ore preferably contains a mineral having a particle size of 5 μm or less. This can increase the surface area of the natural ore in the ceramic containing the natural ore. Then, the water in contact with the ceramic may come into contact with more natural ore, and the alkali metal and / or alkaline earth metal contained in the natural ore may be more eluted into the water.

(Means of contact)
The means for bringing the ceramic into contact with water is not particularly limited, and for example, a means for bringing the ceramic into contact with water in the process of arranging the ceramic inside the water purifier and purifying the water, water exemplified by a water storage tank or the like can be used. The ceramic may be arranged inside the storage container, and may be a means including one or more of various means for contacting the ceramic with water, which is exemplified by means for contacting the ceramic with water during storage of water.

It is preferable that the means for bringing the ceramic into contact with water includes a means for arranging the ceramic inside the water purifier and bringing the ceramic into contact with water in the step of purifying the water. As a result, it is possible to both remove impurities that may affect the quality of gypsum board and make the water mineral-containing water.

(Mineral-containing water)
The lower limit of the ratio of the alkali metal and / or alkaline earth metal contained in the mineral-containing water obtained by the contact step is preferably 20 ppm or more, more preferably 25 ppm or more, still more preferably 27 ppm or more. ..

Since the lower limit of the ratio of alkali metal and / or alkaline earth metal contained in mineral-containing water is the above-mentioned ratio, when the mineral-containing water contains ⁴⁰ K and / or ⁸⁷ Rb, the mineral-containing water is ⁴⁰ K and / or Or it can be expected to contain even more ^{87 Rb. By further containing 40} K and / or ⁸⁷ Rb in the mineral-containing water, the environment around the gypsum board can be improved by the trace amount of high-energy particles emitted ^{by the 40} K and / or ⁸⁷ Rb adhering to the surface of the gypsum board. More promising.

As described above, a small amount of high-energy particles can improve the environment around the gypsum board even when a part or all of the surface is covered. Therefore, by setting the lower limit of the ratio of alkali metal and / or alkaline earth metal contained in mineral-containing water to the above ratio, the environment around the gypsum board is improved even when a part or all of the surface is covered. You can expect even more to do.

[Spraying process]
The spraying step is a step of spraying the mineral-containing water obtained in the contact step on at least one surface of the gypsum board. By the spraying step, calcium sulfate on the surface of the gypsum board, which can be separated from the gypsum board in the form of powder or the like, can be eluted into the sprayed mineral-containing water and permeated into the microstructure of the surface of the gypsum board together with the mineral-containing water. In addition, various components contained in the mineral-containing water may adhere to the surface of the gypsum board by the spraying step. The adhesion of various components contained in mineral-containing water to the surface of gypsum board will be described in more detail in the drying step.

The surface on which the mineral-containing water is sprayed is not particularly limited. The surface on which mineral-containing water is sprayed includes a surface that is on the space side where organisms are present when gypsum board is used as a wall structure, a ceiling structure and / or a floor structure (hereinafter, also simply referred to as "wall structure, etc."). Is preferable. Thereby, when the mineral-containing water can release high-energy particles, more of the high-energy particles released by the mineral-containing water can be released to the space side where the organism is present, and the environment can be improved. The improvement of the environment by high energy particles will be described in more detail in the drying process.

(Gypsum board)
The gypsum board on which the mineral-containing water is sprayed is not particularly limited, and a conventional gypsum board may be used. By using gypsum board, which is a building material having excellent fire resistance and sound insulation, it is possible to provide a function of improving the environment in addition to various excellent features of gypsum board.

[Conductor placement process]
The conductor arranging step is a step of arranging the conductors at least substantially parallel to the surface on which the mineral-containing water is sprayed. The conductor arranging step can generate a magnetic field perpendicular to the surface on which the mineral-containing water is sprayed when the conductor is energized.

The arrangement of the conductors is not particularly limited as long as it is substantially parallel to the surface on which the mineral-containing water is sprayed, and may be an arrangement including one or more of a linear arrangement, a curved arrangement, a bent arrangement, and a ring-shaped arrangement. The arrangement of the conductors preferably includes a ring-shaped arrangement. As a result, the magnetic field perpendicular to the surface on which the mineral-containing water is sprayed is strengthened around the conductors arranged in a ring shape. Therefore, a magnetic field perpendicular to the plane on which the mineral-containing water is sprayed can be generated even more.

The order in which the conductor arranging steps are performed is not particularly limited, and may be performed before the spraying step or after the spraying step.

[Conductor connection process]
When the gypsum board manufacturing process includes a conductor arranging step, the gypsum board manufacturing process installs the first end, which is one end of the conductors arranged in the conductor arranging process, and is the other end of the conductors. It is preferable to include a conductor connecting step of connecting the two ends to the power supply. As a result, the conductor can be energized and a magnetic field perpendicular to the surface on which the mineral-containing water is sprayed can be generated.

The lower limit of the average potential difference between the first end portion and the second end portion is preferably 40 V or more, more preferably 45 V or more, and further preferably 50 V or more. This can generate even more magnetic fields.

The upper limit of the average potential difference between the first end portion and the second end portion is preferably 240 V or less, more preferably 200 V or less, and further preferably 160 V or less. As a result, a magnetic field can be generated while reducing heat generation and the like in the conducting wire.

The power source is not particularly limited, and may be a power source configured by using a storage battery, a power source configured by using a generator, or a conventional power source exemplified by a commercial power source. The power source is preferably a commercial power source. Thereby, the average potential difference between the first end portion and the second end portion can satisfy the above-mentioned lower limit and upper limit.

[Drying process]
The drying step is a step of drying the gypsum board sprayed in the spraying step. Due to the drying process, alkali metals and / or alkaline earth metals contained in mineral-containing water may adhere to the surface of gypsum board.

Natural ores containing alkali metals and / or alkaline earth metals may contain ^{40 K, which is an isotope of potassium, and 87} Rb, which is an isotope of rubidium. ⁴⁰ K can be transformed into ⁴⁰ Ca, a stable isotope of calcium. Also, ⁸⁷ Rb can be transformed into ⁸⁷ Sr, a stable isotope of strontium. A small amount of high-energy particles (electrons) emitted when these elements change can improve the environment through the generation of atmospheric ions and the like. In addition, trace amounts of high-energy particles can exhibit a hormesis effect that has a beneficial effect on the living body.

By performing the drying step, these elements can adhere to the surface of gypsum board when ^{the natural ore contains 40} K and / or ^{87 Rb.} Therefore, according to the invention according to the first feature, the stress of the organisms around the gypsum board is reduced by the trace amount of high-energy particles emitted by the trace ^{amount of 40} K and / or ^{87 Rb adhering to the surface of the gypsum board.} Can be expected. Also, trace ^{amounts of high-energy particles emitted by trace amounts of 40} K and / or ⁸⁷ Rb can exhibit a hormesis effect and have a beneficial effect on the organisms around the gypsum board.

Therefore, it can be expected that the gypsum board subjected to the drying step will improve the environment around the gypsum board so as to reduce the stress of the organism and / or to have a beneficial effect on the organism. Also, regarding the emission of high-energy particles, ⁴⁰ Ca produced by the change of ⁴⁰ K is a stable isotope of calcium, so it does not affect the quality of gypsum board containing calcium sulfate as the main component. It can be expected to improve the environment around gypsum board.

Regarding high-energy particles, since alkali metal and / or alkaline earth metal is attached to the surface of the gypsum board after the drying process, trace amounts of high-energy particles are highly ionized alkali metal and / or alkaline earth metal atoms. It can be expected to collide with and excite the electrons of the atom. Excited electrons emit a small amount of high-energy electromagnetic waves when they return to the ground state. Further, when a small amount of high-energy particles collide with gypsum board or the like, a small amount of high-energy electromagnetic waves may be generated by bremsstrahlung.

Therefore, it can be expected that a small amount of high-energy electromagnetic waves will improve the environment through the generation of atmospheric ions and the like due to the gypsum board that has undergone the drying process. In addition, the gypsum board that has undergone the drying process can be expected to improve the environment due to the hormesis effect caused by a small amount of high-energy electromagnetic waves.

When the surface of the gypsum board is covered with a covering exemplified by wallpaper or the like, the high-energy particles may generate bremsstrahlung in collision with the covering and generate high-energy electromagnetic waves. Therefore, even if a part or all of the surface of the gypsum board is covered by the dried gypsum board, the environment is improved by a small amount of high-energy electromagnetic waves generated by the bremsstrahlung of a small amount of high-energy particles. You can expect that.

Further, when the surface of the gypsum board is covered with a covering body, high-energy electromagnetic waves (for example, electromagnetic waves having a wavelength shorter than 10 pm) can pass through the covering body. Therefore, even if a part or all of the surface of the gypsum board is covered with the gypsum board that has been subjected to the drying step, it can be expected that the environment will be improved by a small amount of high-energy electromagnetic waves that have passed through the covering body.

By the way, the inorganic powder exemplified by calcium sulfate or the like can give stress to various organisms including humans. By preventing the generation of such powders, the environment can be improved so as to reduce the stress exerted on the organism by the inorganic powders.

By the spraying step and the drying step described above, calcium sulfate on the surface of the gypsum board eluted in the spraying step can be precipitated and retained inside the microstructure on the surface of the gypsum board. As a result, calcium sulfate on the surface of the gypsum board, which can be separated from the gypsum board in the form of powder or the like, can be deposited and retained inside the microstructure on the surface of the gypsum board. Therefore, it is possible to prevent the generation of inorganic powder due to the peeling of calcium sulfate and improve the environment.

When the gypsum board manufacturing process includes a conductor arranging step and a conductor energizing step, the conductor having an average potential difference of 40 V or more between the first end and the second end can generate a magnetic field perpendicular to the surface on which the mineral-containing water is sprayed. .. Since the magnetic field can cross the covering, the magnetic field can reach the surface on which the mineral-containing water is sprayed even if a part or all of the surface of the gypsum board is covered.

When an ionized element moves in a magnetic field, the charged ionized element receives a force in a direction perpendicular to the plane formed by the direction of the magnetic field and the direction of movement, and can rotate. Rotating ionized elements can generate heat.

Therefore, the magnetic field that reaches the surface on which the mineral-containing water is sprayed can cause the ionized alkali metal and / or alkaline earth metal contained in the sprayed mineral-containing water to rotate. Then, the heat generated by this rotational movement can promote drying. As a result, calcium sulfate is more retained inside the fine structure in the drying step, the generation of inorganic powder due to the peeling of calcium sulfate can be further prevented, and the environment around the gypsum board can be improved.

[Gypsum board manufactured by the method of this embodiment]
The gypsum board produced by the method of the present embodiment can improve the environment by preventing the generation of inorganic powder due to the peeling of calcium sulfate from the gypsum board.
In addition, the gypsum board produced by the method of the present embodiment reduces the stress of organisms around the gypsum board by a small amount of high-energy particles when ^{the natural ore contains 40} K and / or ^{87 Rb.} It can be expected that the hormesis effect will have a beneficial effect on the organism.

Further, the gypsum board produced by the method of the present embodiment has a small amount even if a part or all of the surface of the gypsum board is covered when ^{the natural ore contains 40} K and / or ^{87 Rb.} It can be expected that the environment will be improved by a small amount of high-energy electromagnetic waves generated by the bremsstrahlung of high-energy particles.

High energy electromagnetic waves can pass through the covering. Therefore, in the gypsum board manufactured by the method of the present embodiment, even if a part or all of the surface of the gypsum board is covered, a small amount of high-energy electromagnetic waves passing through the covering body improves the environment. Can be expected.

Therefore, according to the present embodiment, it is possible to provide a method for producing gypsum board, which can improve the environment even when a part or all of the surface is covered.

[Putty material manufacturing process]
The putty material manufacturing process includes at least a mixing process of mixing used waste gypsum board powder and natural radioactive mineral-containing ceramic powder. The putty material manufacturing step preferably further includes a watering step of adding water to the putty material obtained by the mixing step. By including the water addition step, the putty material becomes gel-like, and it is possible to easily fill the gaps of the gypsum board with the putty material.

[Mixing process]
The mixing step is not particularly limited as long as it is a step of mixing the waste gypsum board powder used for the putty material and the ceramic powder containing natural radioactive minerals, and these are used for the putty material by using various mixing means of the prior art. This may be a step of mixing the powders of. By the mixing step, a putty material containing used waste gypsum board powder and natural radioactive mineral-containing ceramic powder can be obtained.

The cost of disposing of used waste gypsum board can be a great burden for businesses and the like who use gypsum board. In addition, the environment can be burdened by discarding used waste gypsum board.

Further, the wall structure or the like constructed by the method of the present embodiment may have a trace amount of ⁴⁰ K and / or ⁸⁷ Rb on the surface of the gypsum board. As a result, it can be expected that the stress of surrounding organisms will be reduced by the trace amount of high-energy particles emitted by the trace ^{amount of 40} K and / or ^{87 Rb.} In addition, trace ^{amounts of high-energy particles emitted by trace amounts of 40} K and / or ⁸⁷ Rb can exhibit a hormesis effect and have a beneficial effect on surrounding organisms.

FIG. 1 is a schematic view showing a flow in which a wall structure or the like of an embodiment emits a small amount of high-energy particles. Using FIG. 1, the filled putty material F in the wall structure or the like constructed by the method of the present embodiment contains a small amount of high-energy particles (reference numerals P1-P6 in FIG. 1) and high-energy electromagnetic waves (reference numeral R1 in FIG. 1). , R2) will be released to improve the environment.

In the wall structure or the like constructed by the method of the present embodiment, atoms ( ⁴⁰ K, etc. in FIG. 1) derived from the natural radioactive mineral-containing ceramic component contained in the filled putty material F are high-energy particles or the like (for example, electrons). , Gamma rays, and helium nuclei.

Bremsstrahlung is generated when a part of the emitted high-energy particles (reference numeral P1 in FIG. 1) collides with the covering body W such as wallpaper, and a small amount of high-energy electromagnetic wave R1 can be emitted. Then, this trace amount of high-energy electromagnetic wave R1 can enter the space S where the living body is present and improve the environment through the generation of atmospheric ions and / or the hormesis effect. In addition, a part of the high-energy particles (reference numeral P2 in FIG. 1) crosses the covering W such as a wallpaper and enters the space S where the living body is present, emits high-energy electromagnetic waves, generates atmospheric ions, and / or has a formesis effect. The environment can be improved through such means.

However, when the putty material does not contain the gypsum component, a part of the released high-energy particles (reference numeral P3 in FIG. 1) can be absorbed by various molecules (for example, water molecules) contained in the putty material. Due to this absorption, high-energy particles and the like do not enter the space S, and the effect of improving the environment may be uncertain.

In the wall structure or the like constructed by the method of the present embodiment, since the putty material F contains a gypsum component, it contains abundant calcium atoms (Ca in FIG. 1) derived from the gypsum component.

Then, this trace amount of high-energy electromagnetic wave R3 can enter the space S where the living body is present and improve the environment through the generation of atmospheric ions and / or the hormesis effect.

Further, a part of the released high-energy particles and the like (reference numeral P7 in FIG. 1) can collide with the calcium atom contained in the gypsum component, excite the calcium atom, and ionize the electron of the calcium atom. The electrons ionized from the calcium atom can be emitted as high-energy particles (reference numeral P8 in FIG. 1).

The high-energy particles P8 can enter the space S where the living body is present beyond the covering body W such as wallpaper, and improve the environment through the emission of high-energy electromagnetic waves, the generation of atmospheric ions, and / or the formesis effect.

Therefore, in the wall structure or the like constructed by the method of the present embodiment, high-energy particles or the like are more reliably released and released by the calcium atom contained in the gypsum component than when the putty material F contains only the natural radioactive mineral-containing ceramic component. High-energy particles and the like can be put into the space S where the living body is. Then, a small amount of high-energy electromagnetic waves entering the space S can improve the environment through the generation of atmospheric ions and / or the hormesis effect. Further, a small amount of high-energy particles entering the space S can improve the environment through emission of high-energy electromagnetic waves, generation of atmospheric ions, and / or hormesis effect.

Therefore, according to the wall structure and the like constructed by the method of the present embodiment, by using a putty material containing both a gypsum component and a natural radioactive mineral-containing ceramic component, a used waste gypsum board or the like can be used as a gypsum component. Not only can it be effectively used, but it can also be realized that the putty material more reliably releases a small amount of high-energy particles and the like due to the calcium atoms contained in the gypsum component to improve the surrounding environment.

The covering body W can give the wall structure or the like an appearance or the like according to the place of construction. Further, it is possible to prevent the generation of inorganic powder from the surface covered by the covering body W.

As described above, a small amount of high-energy particles and high-energy electromagnetic waves can improve the environment around the gypsum board even when a part or all of the surface is covered with the covering W. Therefore, according to the wall structure or the like constructed by the method of the present embodiment, the surrounding environment can be improved even when a part or the whole of the surface is covered.
