Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a magnetic material using a hydrothermal-

More particularly, the present invention relates to a method of manufacturing a magnetic material using a cobalt river basalt, and more specifically, by specifying the composition ratio of the base material and the cobalt river basalt, it is possible to prevent the basalt component from melting at high temperature, The present invention also relates to a method of manufacturing magnetism and a method of manufacturing the same using a Hantan river basalt which is capable of lowering the firing temperature of the base material and lowering the energy consumption rate when the chaebol is roasted.

There are porcelain and iron bowls for eating food. Among them, magnetism has a certain level of strength compared to ironware, but relatively rarely contains harmful substances to human body, so it is preferred to use ironware in recent years.

Generally, such a magnet is made of clay or ceramics as a base material, and the surface is coated with a glaze, followed by roasting. However, since most of the materials of the conventional magnet are large-sized, they do not use any other ingredients that give a beneficial effect to the human body. Therefore, it has a limit to provide high cognitive effect on the product (self) because it can not follow trends such as well-being and eco-friendliness which are emerging in recent years.

On the other hand, there are basalt rocks composed of silica, aluminum oxide, diiron ferric oxide, calcium oxide, potassium oxide, sodium oxide and magnesium oxide. These basalt rocks are used extensively as building materials and decorative materials by processing the stone itself because of their excellent strength, but the amount of basalt sludge that is discarded as waste is also increasing, which causes environmental destruction.

In recent years, the sale of local beauty products using Korean beauty has been increasing. At this time, by recycling the basalt sludge that is discarded as the waste material, it is possible not only to reduce the production cost but also to prevent environmental destruction. In addition, such basalt rocks have various properties beneficial to the human body, and thus can be utilized as magnetic materials for well-being when used as a magnetic material.

However, in general, high-grade magnetite is produced by roasting at a high temperature of 1,100 ° C. or higher. The melting temperature of the basalt sludge is about 1,100 ° C., so that at the high temperature of the jade roasting, It can not be used because it is in an amorphous state, so that it has been difficult to utilize it as a material of high-grade magnetism, despite the above-mentioned environmentally friendly and beneficial properties to human body.

On the other hand, in the case of a conventional magnet having a handle or other decoration, the body, handle or other decoration are formed separately, and then a handle or other decoration is attached to the molded body and baked to produce a finished product.

However, after designing the product with only the body without the first handle or other decoration, after the body has been molded, the product design has been changed to a shape with a handle or other decoration, Handles or other decorations may be affixed.

However, in the case of a magnet made only of a base material such as clay or ceramics of the related art, when a considerable time elapses after the body molding as described above, the water of the body dries up and water is again applied to attach the body and the handle or other decoration. There is a problem in that the quality of the product deteriorates due to the fact that the handle or other decoration attached after the grilling and the chaebol are roasted easily, or the finish of the attached portion is not achieved properly.

Patent Document 1 discloses a cooking pan using basalt as a main material. However, the cooking pan is manufactured by heating the basal body made of basalt to a temperature of 1,200 캜 or higher to melt the basalt contained in the main body, It is a basic feature to form a molten layer on the entire side surface and does not disclose a feature for preventing the basalt component from melting down and utilizing it as a magnetic material when roasting a jar at high temperature of the present invention. The following Patent Document 2 describes an auxiliary feed using basalt sludge, but does not disclose contents for utilizing basalt sludge as an advanced magnetic material.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a flow chart showing a magnetic manufacturing method according to an embodiment of the present invention in order. FIG.

Generally, porcelain is made of clay or ceramics and then coated with glaze on its surface, followed by roasting.

Recently, as well-being has emerged, attempts have been made to use self-made materials that are beneficial to the human body.

In this embodiment, by using basalt having a property advantageous to the human body as magnetic material, it is possible to provide a magnetic body that provides a beneficial effect to the human body. The magnetic body of the present embodiment is preferably used as a dishware have.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below.

In addition, to include an element throughout the specification does not exclude other elements unless specifically stated otherwise, but may include other elements.

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a flow chart showing a magnetic manufacturing method according to an embodiment of the present invention in order. FIG.

Referring to FIG. 1, first, 20 to 90% by weight of a base material and about 10 to 80% by weight of finely ground basalt are mixed with water to a size of about 0.1 to 10 μm to prepare a blend material as a primer mixture (S1). At this time, if the size of the basalt is excessively larger than 10 탆, there is a problem that it is not mixed well with the compounding material and a foreign body sensation occurs. If the size of the basalt is less than 0.1 탆, the yield from the basalt sludge is decreased . Thereafter, this compounding material is kneaded and formed into various magnetic forms desired by the user, such as a box, a jar, or a bowl (S2).

At this time, the base material used for the compounding material may be any one of alumina, feldspar and loess, or a combination of two or more thereof. However, the base material of the present invention is not limited thereto, and a variety of materials can be used for the base material depending on the strength, color, and texture of the final product.

Here, the alumina is a material of ceramics, and has excellent heat resistance, chemical resistance and strength as an insulator, and can be expected to be lightweight and improved in corrosion resistance when used as a base material. The feldspar is an aluminum silicate mineral containing silicon dioxide as a main component and containing potassium, sodium, calcium and barium. When the content of alumina and feldspar exceeds 90% by weight based on 100% by weight of the total blend material, the blend materials may not be able to be molded because the blend materials do not coalesce when the blend is molded. If the content is less than 10% by weight, the content of the basalt may be relatively high, which may melt the processed product at a temperature of 1,100 ° C or higher, and the firing itself may become impossible.

In addition, the loess is a natural soil composed of silica and soil containing hydrous iron oxide and anhydrous iron oxide, and has a red or yellowish color, and is excellent in anti-fungal effect, deodorizing effect and heat radiation effect. If the content of the loess is more than 90% by weight with respect to 100% by weight of the total compounding material, there may be a problem that cracks are generated in the magnetic body after roasting. When the content of the loess is 10% , The content of the basalt is relatively high, so that the processed product is melted at a temperature of 1,100 ° C or higher, and the plasticity itself becomes impossible.

The base materials alumina, feldspar and loess have a melting point of about 1,700 ° C. Therefore, when the magnetic material is mixed only with these components, the burning temperature at the time of chaebol burning increases, and the energy consumption rate used for raising the heat rapidly increases. However, in the present embodiment, basalt is mixed and used as a blending material. Thus, it is possible to reduce the energy consumption rate by lowering the firing temperature from 1,100 to 1,350 DEG C, which is lower than that at the time of chaebols.

The basalt rocks absorb far-infrared radiation and heavy metals in the body. It has a function of decomposing, which expands capillary blood vessels and promotes metabolism, thereby providing fatigue recovery, prevention of skin diseases and prevention of various adult diseases, and an effect of refreshing hair by releasing negative ions can be expected.

In addition, since the basalt rock has strong antimicrobial activity, it suppresses the reproduction of mites and fungi, which cause atopy, and has strong adsorption and deodorizing properties, so that it can be expected to reduce various unpleasant odors and formaldehyde. Also, the amount of uranium, which is a radioactive material, in the basalt rock is considerably smaller than that of basic igneous rock, granite, sandstone, limestone, andesite and shale.

Basalt powders used in this embodiment can be produced using basalt sludge, and the production of such basalt powders can be carried out through the following precipitation step, a filtration step, a dehydration step and a heating step.

In the sedimentation step, the basalt sludge is mixed with water to make a dispersion, and then the sediment is allowed to settle to precipitate the basalt particles, and then remove the foreign matter on the water. Since basalt sludge is mainly produced during the processing of stone, a small amount of mineral oil may be introduced during the cutting process, and the introduced mineral oil is removed as foreign matter in the precipitation step.

In the fertilizing step, the basalt dispersion is sieved to remove large sized basalt particles. At this time, if the sieve interval is too large, foreign matter may be generated when mixed with the base material due to large basalt particles. If the sieve interval is too narrow, the yield from the sludge may be decreased.

In the dehydration step, the basalt dispersion that has undergone the fertilizing step is dried to remove water. At this time, for smooth dehydration, a supernatant may be previously removed by using a centrifuge, and a dryer may be used. If necessary, the supernatant may be dried using a dryer immediately.

Thereafter, if necessary, the de-ironing step can be carried out. In the de-ironing step, the dried basalt particles are passed through a de-ironing machine to remove iron powder which can flow in the stone processing.

In the heating step, the basalt particles that have undergone de-ironing are heated to a high temperature to burn out the microorganisms contained in the basalt. At this time, there is no particular restriction on the heating temperature and time, but sufficient heating is required to remove microorganisms. The basalt produced by the pulverization is a magnesium-rich material, which is an inorganic substance required for the human body. When used as a magnetic material, the above-mentioned effects can be expected as well as effects such as relieving stress and sleeping. In addition, since the content of iron in the basalt rock is high, it can be colored beautifully after the final conglomerate when used as a magnetic material, and it can exhibit a natural and profound aesthetic feeling in which a large number of voids are formed on the surface.

In particular, the basalt is distributed evenly in Korea, and the basalt collected from the rivers of the river is very suitable for the self-production according to the present invention.

The Hantan River is a river formed by the discharge of lava from the Mt. Ori, Pyeonggang-gun, Gangwon-do, and the lava extending about 99km in length. The lava is 40m long and flows into the Imjin River through Cheolwon-gun and Gyeonggi-do.

As Hantan River tells us, the basalt collected here is superior to basalt in other areas and is therefore well suited for self production according to the present invention.

Next, after the molded body is naturally dried, it is heated at 900 to 950 DEG C for about 7 to 9 hours, preferably about 8 hours, at a relatively low temperature in a heat-resistant tube such as a kiln for baking porcelain or earthenware (S3). At this time, setting the firing temperature to 950 DEG C or less is intended to increase the water absorption rate to remove the moisture of the processed product as much as possible, but not to cause problems due to cracking and deformation of the processed product after the fired.

Next, the glaze is uniformly coated on the surface of the pre-baked processed body, preferably at a thickness of 1 mu m or less (S4).

The glaze is used not only to make the product beautiful by covering and glossing the surface of the processed body, but also to strengthen the surface of the processed body and to prevent the dirt from burning. In addition, it has the function of eliminating the absorbency of the processed body and increasing the resistance of the final product to water or chemicals.

At this time, the glaze can be generally used feldspar glazes containing components such as zircon, limestone and kaolin, but it is preferable to use glaze ash. The above-mentioned volcanic glaze is a volcanic ash blended at a base rate of 100 to 200,000 years ago and mixed with a base glaze at a predetermined ratio, and has considerable homogeneity with respect to age and composition with respect to the basalt composition. The above volcanic ash is called a volcanic clay, which is discharged in a crushed state due to a shock due to volcanic activity or a gum of a volcanic gas. Among these volcanic clusters, sediments of small grains having a size of about 0.25 to 4 mm .

In addition, since the volcanic ash glaze contains no harmful components to the human body, it is effective for well-being when used in the magnet, and the price is low, so that the production cost can be lowered.

In addition, the ash glaze can increase the firing temperature of the basalt component contained in the processed body, thereby further preventing the melting of the basalt component at a high temperature of 1,100 ° C or more.

On the other hand, the glaze affects the final coloring of the self. The volcanic ash glaze exhibits similar color when compared with a container made of basalt without the application of glaze. Therefore, when the self- The effect of expressing the color of the basalt rock included in the present invention more beautifully.

Next, the processed body to which the glaze has been applied is heated at a low temperature for a predetermined time, and gradually heated to 1,100 to 1,350 ° C, more preferably to 1,220 to 1,250 ° C, (S5).

At this time, the reason why the temperature of the chrysanthemum roasting is set to a high temperature of 1,100 DEG C or more is that if the heating temperature is lower than this, the processing is not properly performed and the strength of the magnetic is weakened . In addition, if the temperature of the jaebol roasting exceeds 1,350 ℃, no significant effect can be expected compared to the amount of energy used to raise the heat.

Generally, the melting temperature of the basalt rock is about 1,100 ° C., and when it is above 1,100 ° C., when it is roasted, it can not be baked at a high temperature because it becomes amorphous. However, when the base material of a specific component is used and the mixing ratio of the base material and the basalt is specified, the basalt does not melt even when the temperature of the jarging roasting is raised to 1,350 캜, so that it can be used as a magnetic material. This is because the basalt rock contains silica (SiO ₂ ) in an amount of about 42 to 50 wt%, but silica (SiO ₂ ) is contained in about 60 wt% or more also in the base material feldspar or loess so that the effect This is because the melting point of the basalt is increased.

On the other hand, in the case of a conventional magnet having a handle or other decoration, the body, handle or other decoration are formed separately, and then a handle or other decoration is attached to the molded body and baked to produce a finished product. However, after designing a product made only of the body without the first handle or other decoration, after the body is molded, the shape of the product is changed to a shape with a handle or other decoration, and after a considerable time has elapsed after the body is formed, Other decorations may be attached.

However, in the case of a magnet made only of a base material such as clay or ceramics of the related art, when a long time more than one day elapses after molding the body as described above, the water of the body dries up and water is again applied to attach the body, the handle, There is a problem in that the quality of the product is deteriorated due to the fact that the handles and other ornaments to be attached later are easily fallen off after being roasted and chaebols are roasted,

However, according to the present embodiment, since the viscosity of the basalt is good in the compounding material, the body and the handle or other ornaments adhere well to each other even if a handle or other ornament is attached after a considerable time has elapsed since the body was first molded It is possible to prevent the deterioration of the quality of the product due to the proper finishing of the attached portion without being easily deteriorated even after the grinding process and the chrysanthemum roasting, so that the product can be easily processed and the minute shape magnet can be easily and conveniently manufactured do. Also, since the specific gravity of the basalt rock is 3 or less, it is possible to manufacture the magnet more flexibly due to the phenomenon of sagging due to gravity.

Hereinafter, the present invention will be described in more detail with reference to Comparative Examples and Examples, but the present invention is not limited by the following Examples in order to facilitate a specific understanding of the invention.

The specimen was molded into a rectangular parallelepiped of 7 × 5 × 1 (cm) with various mixing ratios, dried, and dried for about 8 hours at about 950 ° C., And then the surface of the rectangular parallelepiped was melted, whether it was molded as a processed body, and whether cracks were formed on the surface of the roughened surface after grinding. The base material was alumina, feldspar and loess.

Referring to Table 1, Sample 12 having a rectangular parallelepiped composed of only 100 wt% of basalt and Sample 11 having a basalt mixing ratio of 90 wt% in a rectangular parallelepiped had meltdown at 1,100 DEG C during chrysanthemum roasting, It can be seen that it is difficult to use it in the magnet for which the chaebol roasting is required.

On the other hand, in Sample 1 to Sample 10 in which the mixing ratio of basalt rocks in the rectangular parallelepiped was 80% by weight or less, the melting did not occur at 1,100 ° C during chrysanthemum roasting.

However, in the case of Sample 2 having a basalt mixing ratio of 5% by weight of a rectangular parallelepiped and Sample 1 having no basalt at all, when alumina or feldspar is used as a base material, And it is confirmed that there is a problem that when the loess is used as the base material, cracks are generated in the magnetic body after the chaebol grinding.

That is, when alumina, feldspar or loess is used as the base material, it can be confirmed that the preferable mixing ratio of the basalt which can be used as the magnetic material is 10 to 80% by weight.

The present invention is not limited to the above-described embodiment and the accompanying drawings, but is intended to be limited by the appended claims.
