Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a molded article containing crushed rice husk as a far-infrared radiator.

[Conventional technology]

Conventionally, inorganic ceramics have been used as good infrared radiators, and have already been put into practical use as infrared ceramic heaters. However, in order to emit infrared rays efficiently, it is necessary to carefully select and proportion the inorganic components to be mixed, and also to precisely control the firing temperature, etc., resulting in an expensive product. was. Infrared rays are known to be generated by the vibrational rotation of molecules in gases, and from thermal interactions within molecules or in the entire solid lattice in solids. It is emitted as radiation, and those with longer wavelengths are called far-infrared rays, and in recent years they have come to be widely used mainly for cooking purposes.

However, as mentioned above, they are generally expensive, and as a result, there are problems in using them as building materials or containers that are used in large quantities. Furthermore, there are almost no materials that efficiently emit far-infrared rays at temperatures from room temperature to about 100 degrees Celsius, and no organic substance that efficiently emits far-infrared rays has yet been discovered. It was hoped that a molded radiator would appear.

[Problem to be solved by the invention]

In view of the above-mentioned situation, an object of the present invention is to provide a material and a molded product that can be supplied in large quantities at low cost and that efficiently radiate far-infrared rays.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention comprises a molded article containing crushed rice husks as an efficient far-infrared ray radiator and formed into an appropriate shape. did.

Furthermore, a molded article containing crushed rice husks as a far-infrared ray radiator was constructed by solidifying the crushed rice husks as a far-infrared ray radiator with a binder such as a synthetic resin and molding them into an appropriate shape.

Then, the molded product was molded into a plate shape, a container shape, or a bowl shape.

[Effect]

The molded product containing crushed rice husks as a far-infrared radiator of the present invention having the above-mentioned contents can be produced efficiently (using far-infrared rays emitted from rice husks) at a practical low temperature range from room temperature to about 100°C. The rice husks are crushed into a size that can be easily molded.
It is solidified into an appropriate shape. Furthermore, it is mixed with a binder such as a synthetic resin to improve its moldability and enable injection or compression molding into any shape.

Although the theoretical explanation of the phenomenon in which far-infrared rays are efficiently emitted from rice husks has not yet been made, it is generally known that the greater the infrared absorption ability of rice husks, the greater their radioactivity (radiation activity). Since it is a natural armor that protects the germ from radiation including infrared rays, it is assumed that it also has excellent ability to absorb infrared rays, and as a result, far infrared rays are thought to be emitted efficiently from crushed materials.

The molded material containing the crushed rice husks is then efficiently radiated with far infrared rays, forming the molded material into a plate shape.

When formed into a container or bowl shape, it can be used as a material for various constructions, and when formed into a container or bowl shape, it can be used to store plants,
Far infrared rays have an excellent effect on food, drinks, etc.

[The method and apparatus for producing crushed rice husks used in the detailed description of the invention are as follows:
Japanese Patent Publication No. 57-31943 (method for producing powder of seed coat, trunk, branches, leaves, etc. of siliceous plants containing silicic acid) and Japanese Patent Publication No. 62-61342 (compression and sowing method) by the present applicant. The rice husks are fed into a cavity consisting of a screw and an outer cylinder, the inner or outer surface of which has a spiral shape and whose cross-sectional area gradually decreases, and the rice husks are loaded with a force of 1 to 100 tons per square cm. Under reduced pressure, at a temperature of 150 to 600°C,
After the molecular structure is destroyed and solidified, it is made into powder using a known pulverizer.

The crushed rice husk itself maintains a certain shape if it is compressed under high pressure, but its strength is weak, so it is desirable to hold it in a frame. More preferably, the crushed rice husks are mixed with a binder such as a synthetic resin and molded into a desired shape by injection molding or compression molding in the same manner as in the production of ordinary synthetic resin-sealed molded products.

Therefore, in order to emit more far infrared rays from a molded product containing crushed rice husk, it is necessary to increase the content of crushed rice husk, but in normal crushing, even the needle-shaped crystals of rice husk are crushed. It is impossible to do so, and it has poor compatibility with synthetic resins, so increasing this ratio is of course problematic in terms of the finish and strength of the molded product. The product is microscopically rounded by being crushed down to the needle-like crystals of the rice husks, has good compatibility with synthetic resin, has excellent finish and strength when molded, and according to the applicant's experiments, It was possible to lower the content of synthetic resin to about 5%.

The excellent effects of far infrared rays on plants, food, and drinks have been announced by numerous research institutions and cooking researchers, and the present invention is applicable not only to containers and tableware such as bowls that contain these. It is formed into a plate shape and used as a building material such as wall material, activating the air in a room surrounded by concrete and providing a comfortable living environment.Furthermore, it can be used for other purposes such as flower pots. Or, a kotatsu board, etc., whose temperature rises relatively, can be considered.

Although rice husk is an organic substance, it is an excellent emitter of far-infrared rays, as evidenced by the large number of inorganic substances incorporated into its tissue.

The present invention was developed by focusing on the wide variety of inorganic substances.

The table below shows the content of inorganic components in rice husks produced throughout the country. The inorganic components contained in the left column of the table are shown by element symbols, and the right column shows the average value of the content in pp.
m and C1v, respectively. As can be seen from this table, there are many types of inorganic substances detected, and there is very little variation in the content depending on the production area.As a result, there is little variation in quality as a far-infrared radiator, so it is effective as an industrial material. It turned out to be.

As mentioned above, the inorganic substances incorporated into the tissue of rice husks are almost all made from the compositional elements of various ceramics. We will describe the results of measuring the spectrum and efficiency of a completely black body, which is ideal as a far-infrared radiator.

FIG. 1 is a schematic diagram of the measuring device, and 1 in the figure indicates a bowl, and the bowl is inserted into a circular hole opened on one side of a sealed heating box 2, with the elevated side facing inward. The heating box 2 is sealed and fixed in a state where the heating box 2 is contained, and boiling water 3 is poured into the bottom of the heating box 2.
The bottom surface of the heating box 2 is heated with an electric heater 4, the temperature inside the heating box 2 is stabilized at the steam temperature, and the generated steam is exhausted from the exhaust stack 5, and the steam is discharged from the bowl 1 that has reached thermal equilibrium. Infrared spectral analyzer 6 measures the emitted far infrared rays.
It is detected by

The infrared spectral analyzer 6 is MINA
5A-400C manufactured by RAD SYSTEMS INC.
In VF, ELECTRO0PTICAL INDUST
Calibration was performed using a blackbody furnace manufactured by RIES INC. Confirm that the outer surface temperature of the heating box 2 is 100°C using a contact surface thermometer (HL-200), and preheat it for about 50 minutes until the surface temperature of the sample bowl 1 becomes stable. The stable temperature continued to be 91.4°C. Note that during this experiment, the room temperature was 25° C. and the humidity was 54%.

The spectrum of far infrared rays emitted from Bowl 1 measured under the above experimental conditions is shown in Figure 2 together with the radiation spectrum of a completely black body (dotted line), and the radiation efficiency of Bowl 1 with respect to the completely black body is shown in Figure 3. As shown in the figure. In the figure, the region below the wavelength of about 3 μm is omitted because the error is large due to the influence of water vapor in the air.

The above measurements have shown that far infrared rays are emitted very efficiently from molded products containing crushed rice husks, and that far infrared rays are emitted uniformly over a fairly wide wavelength range. Ta.

〔Effect of the invention〕

According to the molded product containing crushed rice husks as a far-infrared radiator of the present invention as described above, it emits far-infrared rays in a relatively low temperature range from room temperature to about 100 degrees Celsius very efficiently and in a wide range of wavelengths. It is possible to uniformly irradiate far-infrared rays onto plants, 4° dishes, and drinks housed in shaped containers, thereby bringing out the effects of far-infrared rays.

In addition, when synthetic resin etc. are used as a binder,
Molded products of various desired shapes can be made, and can be used in the same way as ordinary synthetic resin molded products as molded products that emit far-infrared rays.

Building materials and containers that can be molded into plate shapes, container shapes, and bowl shapes and have a far-infrared radiation effect;
Tableware etc. can be provided at low cost.
