Recently, research has been focused on heating from the viewpoint of preserving the global environment. I have. However, with conventional far-infrared radiation materials,
Two grindings and long firings at high temperatures are required, which in turn consumes enormous amounts of energy. Therefore, considering the enormous energy consumed to obtain the far-infrared radiating material, whether the far-infrared radiating material as a conventional ceramics recovers the enormous energy consumed, and whether it is surplus, It is a serious question.

Therefore, the present invention has been made in view of the above circumstances, and it is possible to obtain a far-infrared effect, particularly an energy-saving effect, with a small amount of processing without consuming a huge amount of energy, and at a low cost. An object of the present invention is to provide an infrared radiating material and a use product thereof.

[0007]

SUMMARY OF THE INVENTION The present inventor has been conducting research on the composition and characteristics of shell fossils for many years, and at the same time, has been promoting the cultivation of fish and shellfish, the environmental conservation of water and sediment in and around the aquaculture fishing grounds, and the acquisition of the same. We have been conducting research on the cooking of farmed seafood. As a result, when aquaculture and baking of natural seafood, if a granular shell fossil of a specific component is laid in place of the water on the tray under the gas grill net and filled with water, baking will generally have a high far-infrared effect. It has been found that it has better finish and better heat than seafood baked with Bincho charcoal, so it burns quickly, and in addition, it loses wateriness and is hard to cool down. They have found that shell fossils have a very high far-infrared effect and arrived at the present invention.

That is, the first aspect of the present invention relates to a method for producing SiO ₂ :

O _5: the 0.057 to 0.065% as a main component, a fossil shells containing other trace elements to the remainder, is a far-infrared radiation material, characterized in that as an active ingredient.

The far-infrared ray radiating material of the present invention contains a fossil shell containing the above-mentioned components (hereinafter referred to as a far-red shell fossil) as an active ingredient. It is constituted by the addition of shell fossils with greatly different component values. The present invention relates to a field of use of far-infrared shell fossils whose component values are significantly different from those of shell fossils, which have already been accumulated for their effects as water quality improvers, bottom quality improvers or food additives, and have been accumulated. The deep-sea clam fossils used in the present invention are foraminiferal fossils in the archaeological name and calcareous sandstone in the geological name, and are currently produced only in Toyama Prefecture in Japan, but are not limited by the place of production. Any shell fossil from any locality may be used as long as it is a shell fossil having the main components described above. Table 1 shows the analysis values of fossil shellfish produced in Toyama Prefecture.

[0010] More specifically, the deep-sea shelled fossils of the present invention include:
These were mined at several mines in Toyama Prefecture, and were similar to the far-infrared shell fossils of the components shown in Table 1 mined from these mines.

[0011]

[Table 1]

As is clear from the component values shown in Table 1, the fossil shellfish mined in Toyama Prefecture has a large composition and molecular assemblage of shell fossils mined in other regions of Japan. Different, especially silicon, aluminum,
It is characterized by a very high content of iron and potassium and a very low content of calcium, that is, a very low content of calcium carbonate. In addition, there are slight differences in the component values of fossil shellfish between mines and at the same mines due to veins.

Next, the radiation status of far-infrared rays is measured for the far-red shell fossils of Toyama A, which are 30 mm under and those of 73 μm fine powder. The details of the measurement are as follows. 1. Measurement temperature 70 ° C 2. 2. Measurement model Fourier transform infrared spectrophotometer JIR-E500 Measurement conditions Resolution 1 / 16cm Integral count 200 times Detector MCT Figures 1 and 2 show the measured values of far-infrared radiant energy of a 30 mm under sample of fossil shellfish and a 73 μm fine powder sample in the above measurement contents. . Further, FIGS. 3 and 4 show the ratio between the far-infrared radiation energy in both samples and the far-infrared radiation energy in the ideal black body, that is, the far-infrared emissivity.

In FIG. 1 and FIG.
The under sample and the 73 μm fine powder sample have little difference in far-infrared ray radiant energy, have a peak value of far-infrared radiant energy in the range of 7 to 9 μm far infrared rays, and show almost the same tendency as an ideal black body. In addition, in FIGS. 3 and 4, both the 30 mm under sample of the far-red shell fossils and the 73 μm fine powder sample show high far-infrared red-ray emissivity, especially in the far-infrared range of 5 to 14 μm, which is the wavelength band of all organic substances. , A maximum of 97%, a minimum of 83%, and an average of about 93%. Therefore, it is possible to efficiently use the radiant energy of far-infrared rays in all scenes with these far-red shell fossils of 30 mm or less and fine powder of 73 μm fine powder.

[0015] Accordingly, since far-infrared shell fossils can be used at almost the same far-infrared red-ray emissivity from a fine powder state in micron units to a gravel state of about 3 mm, they are required in accordance with the usage form. It can be used by crushing freely to the particle size. And the simplest form of use of the far-infrared shell fossils is to place the granules of about 5 mm in size on a tray under the gas grill net for grilling fish, instead of water, and place the seafood. Baking is conceivable. By doing so, the baking is quick because of good finish and good heat circulation.

Further, the invention according to claim 2 is characterized in that the trace elements are Sr, Zr, Ru, Y, Ga, Zn, Cu, Ni,
The far-infrared radiating material according to claim 1, which is Mn, Ti, Cl, or Na.

The effect of the above-mentioned trace elements on far-infrared radiation energy from far-infrared fossil fossils is unknown. But,

_{2~13.6%, Fe 2 O 3:} 3.8~4.2%, Mg

Depending on minerals containing 057 to 0.065% as a main component and having no trace elements as described above, high far-infrared radiation energy as shown in FIGS. 1 and 2 or high far-infrared as shown in FIGS. It does not show red line emissivity. Therefore, it is assumed that, due to the synergistic effect of the above main components and these trace elements, the far-infrared shell fossils exhibit high far-infrared radiation energy and high far-infrared red emissivity.

The invention of claim 3 provides a shell made of a humus-soluble crystal, in which various nekton, plankton, algae, seaweed and the like made of calcareous or silicic acid are buried and deposited in the fossil shell. It is a far-infrared radiation material characterized by mixing fossils.

The fossil shellfish (hereinafter referred to as humus fossil) used in the invention of claim 3 is a foraminiferal fossil in the archaeological name and calcareous sandstone in the geological name, similarly to the fossil shellfish fossil.
In Japan, it is produced in Toyama Prefecture, Noto Peninsula in Ishikawa Prefecture, Takayama City in Gifu Prefecture, Hokkaido, Yamaguchi Prefecture, Tokushima Prefecture, Fukushima Prefecture and Kagoshima Prefecture, but there is no limitation depending on the place of production. Humus fossils from any locality may be used as long as they have the characteristics described below. Table 2 shows the analytical values of humus fossils in the main production areas.

More specifically, the humus fossils described above were obtained from the following quantitative analysis tables (Table 3) for samples mined at several mines in Toyama Prefecture, and mined from these mines. And humus fossils analogous to the components shown in Table 3.

[0021]

[Table 2]

[0022]

[Table 3]

The humus fossils mined in Toyama Prefecture differ greatly in the molecular composition from those of humus fossils mined in other parts of Japan, and in particular contain some silicon. It is characterized by a very high calcium content, that is, a very high calcium carbonate content.

The humic solubility is defined as follows. First, humus means that the remains of animals, plants and microorganisms are decomposed by biological communities in a state of low oxygen in the soil, and polyphenols, quinones, and amino compounds are produced, and these substances are oxidized by enzymes and microorganisms. It is polycondensed by the catalytic action of enzymes, inorganic ions, clay minerals, etc., and changes into a dark amorphous colloidal high molecular compound inherent in soil. Therefore, the term "humus-soluble" means that a substance produced by the decomposition and polycondensation of the remains of animals, plants and microorganisms in soil shows solubility. Humic-soluble crystals are the bodies of animals, plants, and microorganisms that have undergone a global transformation over millions of years.

The humus fossil has an aragolite-type crystal structure secreted from a living body, and has a myriad of small pores having a certain effective diameter, and these numerous small pores contain water of crystallization. , And some do not. These pores that do not contain water of crystallization have adsorption performance similar to activated carbon, and may exhibit tens of times the capacity of activated carbon depending on the type of the substance to be adsorbed. And, as mentioned above, this humus fossil is a form of the remains of flora, fauna, and microorganisms that have undergone millions of years of global change, and have changed their appearance. Containing the elements of
In particular, it contains essential minerals abundantly, and even though it is slightly inferior in performance, it shows relatively high far-infrared radiation energy and far-infrared emissivity, similar to the far-red shell fossils, and its degree In the case of far infrared rays in the wavelength band of 5 to 14 μm, a maximum of 85 at a measurement temperature of 60 ° C.
%, A minimum of 73%, and an average of just under 80%.

Therefore, by mixing the fossil shellfish and the humus shell fossil at an optimum particle size according to the use form, it is possible to share the characteristics possessed by each and cover the defects possessed by each. It becomes possible. That is, although far-infrared shell fossils have a high far-infrared effect, adsorption and mineral effects are low. Humus shell fossils have high adsorption and mineral effects, but low far-infrared effects. These disadvantages can be complemented. In addition, the mixture of fossils of far-infrared shellfish and fossil humus leads to the absorption effect and mineral effect when discarded or used as containers and sheets after being used as various far-infrared radiators.
