     The present invention relates to a tile that blocks harmful radiation and a method of manufacturing the same, and more particularly, to provide a magnetic tile and a method of manufacturing the same in order to protect a human body and an object from electromagnetic waves generated from a vein or an electronic / electrical product coming from the surface. do.

     The veins coming from the surface are expressed as EARTH RADIATION or GEOPATHIC STRESS. Searching for "GEOPATHIC" on Yahoo, the US Internet search engine, shows how much mankind is suffering from water veins. Debbi Rye introduces water veins and electromagnetic waves on his homepage (http://www.alternativeways.co.uk). In these results, water veins are radiations that are transformed by weak electromagnetic fields created by groundwater, metals, faults, underground cavities, etc., from which the natural radiation from the earth is harmed. It is said to be. Also, in 1950, Hartmann, Germany, discovered the Hartmann Grid, explaining that the bands of harmful radiation from the surface appear at regular intervals.

     Water veins can delay the treatment of diseased patients or cause diseases such as pain and lethargy, and, in severe cases, blood circulation disorders, even in normal people, and also slow the growth of animals and plants. In fact, people can find groundwater by detecting the vein's radiation, which occurs when groundwater is present underground. The health of the human body may be determined by how long it has been exposed to these veins and above the Earth's radiation.

     As a conventional technique for blocking water vein, the Republic of Korea Utility Model Publication No. 1998-016645 has a large number of permanent magnets arranged irregularly on the concrete floor of the foundation of the building in close contact with the ground, but the characteristics of the permanent magnet This is not done properly and it is not blocking the veins. U.S. Patent U.S. Patent 4,801, 807 uses a method of connecting a thin plate made of a material selected from an additive or a compound of lead and barium with a wire, or installing a container containing these particles on an indoor floor. German Patent Application DE3837622 provides a magnetic plate made of a steel plate magnetized by an electromagnet or a magnet to block water veins. The conventional inventions described above do not technically effectively suppress the vein coming up from the basement, or even use a magnet, there is a problem in that it is rather harmed from the vein by not using the physical principle correctly.

     In addition, such harmful radiation suffers from electromagnetic waves radiated from electronic and electrical appliances such as mobile phones, automobiles, and microwave ovens in addition to water veins.

    The World Health Organization (WHO) has been conducting international electromagnetic wave initiatives since 1996 to establish scientific evidence on the health of electromagnetic waves (EMFs), seeking tolerate limits and blocking measures by 2007.

     Earth's natural radiation is a static magnetic field, which is modulated by groundwater and becomes a vein, and electromagnetic waves emitted from electronic and electronic products contain wavelengths that contain magnetic fields. have.

     Electromagnetic waves with frequency contain electric and magnetic field components. For example, when electricity flows through a wire of an electronic or electric product, an electric field is generated. At this time, electric charges are transferred to the wire, and a magnetic field is generated around the wire. By the same principle, when a magnetic field flows around the human body, electricity flows through the human body, which is mostly water, and thus a disease may occur. The electric field may be blocked by buildings and trees, but is not known to block magnetic fields.

     As a conventional technique related to electromagnetic waves, US Pat. No. 6,001,282 uses tourmaline, and Japanese Patent Laid-Open No. 5-291786 has a multi-layer structure including a sintered ferrite layer which is a soft ferrite as an electron absorber. In addition, Japanese Patent Application Laid-Open No. 5-206676 has an electron absorber having a multi-layer structure in which a metal layer and a magnetic layer are installed, and the magnetic layer is mixed with a binder without sintering the hard ferrite material and manufactured and then magnetized into a sheet. It does not use the characteristics of the pole of the magnet, but simply uses it as an electromagnetic wave absorber.

     As mentioned above, the electromagnetic waves emitted from the veins and the electronic and electrical appliances coming from the surface are harmful radiation and are directly or indirectly harmful to human beings. The present invention has reached the level of weakening the water vein of the prior art, but it does not completely block, and stops only a part of the electromagnetic wave including a magnetic field, the magnetic tile that can block harmful radiation more easily and completely To provide.

     The present invention provides a magnetic tile and a method of manufacturing the magnet attached to the tile to more conveniently block the water vein and electromagnetic waves by using the N pole and the S pole of the anisotropic permanent magnet. In particular, the tiles and magnets are integrated by melting and adhering to each other on the surface of the boundary line by sintering each other. The tile absorbs the fragile brittleness of the magnet, not the tile as a filler to separate the magnet from the magnet, so that the user can conveniently block harmful radiation by attaching it to the floor and wall of the building. In addition, the present invention is a sintering when manufacturing a magnet and firing also to make a tile, the present invention is compression molding by inserting a magnet material and a tile material into a tile mold at the same time and the magnet is attached in one sintering heat treatment There is a characteristic that can produce a magnetic tile.

The present invention relates to a method of manufacturing a magnetic tile that blocks harmful radiation that sinters and magnetizes.

     Hereinafter, the magnet and the magnet tile of the present invention will be described in detail.

     The magnet material used in the present invention is a powder magnet material when the raw material of the magnet is melted and pulverized and then used as a powder to produce a powder, and the sintered magnet material is sintered when the powder magnet material is sintered at high temperature. Before sintering, the powdered magnetic material may be made into a thin cube, a cube, a cylinder, or the like, or may be manufactured in the shape as described above by cutting after sintering. Powdered and sintered magnetic materials are different depending on the magnetic materials, but when magnetized by applying more than 1,000 Oersted magnetic field, they become permanent magnets. In the present invention, an anisotropic permanent magnet magnetized in the direction of the thickness of the magnet is used, hereinafter referred to as a magnet.

     Magnets can be mainly classified into AlNiCo, ferrite and rare earth systems. Ferrite magnets contain barium (Ba) or strontium (Sr) in addition to iron oxides. The residual magnetic flux density of strontium ferrite (Sr-ferrite) magnets varies depending on the manufacturer, but is up to 4,500 Gauss. Rare earth magnets are superior to samarium magnets, and neodymium magnets (Nd Magnets) have a residual magnetic flux density of around 15,000 Gauss and are being improved by technology development.

     In the manufacture of ferrite magnets, iron oxides containing barium and strontium elements are added to iron oxide and other additives are calcined at around 1000 ° C to combine iron oxides and elements. When the calcined compound is ground in a ball mill, it becomes a powdered magnetic material. If necessary, the calcination may be performed after molding the magnetic material into the shape of a magnet to prevent the magnetic material from breaking during compression in the tile mold. The powdered magnetic material as described above is mixed with a binder to form a desired magnet and sintered or fired at 800 ° C. or higher to become a sintered magnetic material. These powdered magnetic materials or sintered magnetic materials are called magnet materials. The magnet material becomes a magnet when magnetized.

     When the residual magnetic flux density is large, the surface magnetic flux density from the magnet is increased to easily block harmful radiation, and the surface magnetic flux density varies depending on the shape and the part thereof. If the intrinsic coercive force (iHc) of the magnetic properties is large, the magnetic field can be maintained for a long time, strontium-based ferrite is manufactured up to 5,000 Oersted.

     In the magnet tile completed by sintering and magnetizing in the present invention, the magnet has a surface magnetic flux density of at least 50 Gauss or more, and if it is less than 50 Gauss, the harmful energy blocking effect is reduced, so that the magnet is at least 50 Gauss or more.

     In the present invention, the thickness of the magnet in the magnet tile arranged on the tile and completed by magnetization is 0.1mm or more and 100mm or less, and when the shape of the magnet is hexahedron, the length of the short side is 1.0mm or more, and the magnet other than the hexahedron is 1.0 It should be at least mm. The thicker the thickness, the greater the surface magnetic flux density, so it should be at least 0.1mm thick. In addition, it is because it is difficult to arrange when the short length of the side or diameter of the magnet is smaller than 1.0 mm, and the upper limit can be equal to the size of the maximum tile. Therefore, when arranging the magnetized magnet in the present invention, the thickness of the magnet is 0.1mm or more and 100mm or less, and the length or diameter of the short side is at least 1.0mm or more.

     According to the present invention, the S pole 12 is positioned in the direction of harmful radiation, the N pole 11 of the magnet is positioned in the opposite direction, and the distance from the adjacent magnets is arranged so that harmful radiation does not penetrate the magnetic field of the magnet. The magnet is arranged so that the shape of the magnet is arranged at the corner of the rectangle when the center of the magnet is connected by a line. The magnets should be arranged at regular distances and placed at the corners of the rectangle for ease of installation.

     In addition, the present invention is to arrange the magnets as described above, the arrangement is located in the corner of the triangle when connecting the center of the magnet in a line. At this time, when the magnet is located at the corner of the triangle can minimize the potato of the magnet can block harmful radiation for a long time. Therefore, the magnets are arranged in a triangle shape.

     In arranging the magnetized magnets of the present invention, the short distance between the magnet and the magnet is 30 times or less of the magnet thickness. The distance between the magnets depends on the type of the magnet, and the greater the magnetic flux density, the greater the distance from the adjacent magnets. Therefore, the shortest distance between the magnet and the magnet is less than 30 times the magnet thickness.

     Further, in arranging the magnets, the thickness or height of the magnets may be different compared to the adjacent magnets. Mounting so that the middle point of the thickness of the magnet coincides with the middle point of the adjacent magnet can be installed in a distance from the magnets, so that the economical installation is possible, but the height of the adjacent magnet or the thickness of the magnet may be different. This is because the effect of the invention is not affected. However, the human body should be located in the N pole direction at least from the midpoint of the magnet thickness, which is the boundary between the N pole and the S pole. This is because the human body is rather harmful when exposed to the magnetic field of the S pole.

     In addition, the present invention can produce a magnetic tile by mixing the powdered magnetic material with the tile material, compressing and molding in the tile mold and magnetizing in the thickness direction of the tile.

      When mixing the raw material of magnetic tile, the average particle size of powder magnetic material should be 0.01mm or more and 30mm or less, and the volume of powder magnetic material should be 10% or more and 95% or less with respect to the total volume of powder magnet material and tile material. By mixing as described above, the particle size of the magnet in the tile, sintered and magnetized in the tile, the particle size of the magnet is 0.01mm or more and 30mm or less, and the volume of the magnet is 10% or more and 95% or less compared to the total volume of the magnet and the tile base material. Provides a magnetic tile that blocks radiation.

     The magnetic tile is mixed with the powdered magnetic material and the tile material, put into a tile mold, compacted, molded, dried, sintered and magnetized. The powdered magnetic material may have a particle size of 0.01 mm or more and 30 mm or less, and the tile material may have a particle size of 500 mesh or less. If the particle size of the powdered magnetic material is less than 0.01mm, the strength of the magnet is weak, and if it is more than 30mm, it is excessively large and the mixing with the tile material is not uniform. Therefore, the particle size of the powder magnet material should be 0.01mm or more and 30mm or less. The finer the particles, the denser the particles and the better the strength and properties.

     The volume of the magnetic material is 10% or more and 95% or less of the total volume of the tile material and the magnetic material, and when the volume of the magnetic material is less than 10%, the magnetic field is small and it is difficult to block harmful radiation. In addition, when the volume of the magnetic material exceeds 95%, the magnet tile can be easily damaged by the impact, and the life is shortened. Therefore, the volume of the magnetic material in the present invention is 10% or more and 95% or less of the combined volume of the binder and the magnetic material.

     The magnet tile magnetizes in the thickness direction of the tile so that the magnet attached to the magnet tile magnetizes in the thickness direction, and the S pole of the magnet is arranged in the direction of generating harmful radiation and the N pole of the magnet is to be protected. It can be used by attaching it to the required use.

     At this time, by manufacturing a magnet tile in which the magnet of the magnet tile and the tile base material is fused at the boundary by sintering, it can be constructed more conveniently to block harmful radiation. Tiles can be placed on the floor of the building to block earth radiation and veins, and also to block electromagnetic waves from electronic and electronic products.

     In order to manufacture the magnetic tile, first, the tile material is prepared as in the general tile manufacturing method, and is manufactured as shown in FIG. 1. The raw material of the tile material serves to separate the magnet, maintains the strength of the tile, or may be a material that generates far-infrared rays that are beneficial to the human body. Tile material in the present invention may be a material containing at least one or more of ocher, feldspar, kaolin, clay, clay, talc. Materials that significantly reduce the magnetic field of the magnet are preferably avoided by demagnetizing the magnet.

     The particle size of the tile raw material is not limited, but in order to prepare a thin tile, it is pulverized to 500 mesh or less. The remaining moisture is dried to 10% or less and, if necessary, a pigment is added to complete the tile material. The finished tile material is put into a tile mold prepared together with the magnetic material and compacted. At this time, the order of placing these magnetic materials and tile materials can be determined according to the place where the magnet is placed in the magnet tile. In order for the magnet to be placed inside the tile, it is completed by inserting a part of the tile material first and then inserting the magnet material and then molding the tile material. In addition, in order to expose the magnet to the outside of the tile, the magnetic material may be placed on the bottom of the tile mold and filled with the tile material, followed by compression molding. Alternatively, the tile material may be put first and then the magnet material may be pressed and molded.

     After the compression and molding as described above, the pattern can be printed on the surface of the tile after drying, and undergoes a sintering process or a firing process. Sintering is a heat treatment for 20 minutes or more within 10 hours at a temperature of 800 ℃ or more and 1400 ℃ or less, at this time the magnetic material becomes a sintered magnet material, fused together with the tile material and firmly attached, and then put into a magnetizer By magnetizing, it becomes a magnet tile. When the temperature of sintering is below 800 ° C, sintering is not enough and the strength is low. When the temperature of sintering is above 1400 ° C, the materials melt and melt together, so that the temperature of sintering is 800 ° C or above and 1400 ° C. Conduct. Such sintering may be performed two or more times as necessary to pattern or paint the tile surface.

     When the sintering process is completed, the magnet is magnetized to form a magnet tile. The magnet should be in the thickness direction of the magnet tile, so that the top surface of the tile is an N pole and the bottom direction of the magnet tile is an anisotropic magnet tile magnetized to the S pole. Then, the lower surface of the magnet tile is attached so as to face in the direction of harmful radiation, and also the harmful radiation can be blocked by directing the upper surface of the magnet to the body and the object to be protected.

     As described above, the magnetic material used in the present invention is not limited to the type of the material, but rather, the physical characteristics of the magnetic tile and the magnetic property of the anisotropy in the thickness direction of the magnet are important.

      Hereinafter, a magnetic tile for blocking harmful radiation for blocking water vein and electromagnetic waves and a method of manufacturing the same will be described in more detail with reference to the embodiments of the present invention.

The raw material of the tile is partially put in the tile mold, and then the sintered magnet material is molded and sintered. Then, the tile material is added to the tile mold, compression molded, dried and sintered. Sintering sintered at 1100 ℃ for 20 minutes to complete the magnet tile and magnetized by hanging a magnetic field with 17000 Oersted to block electromagnetic waves.
