Referring to FIG. 1, in order to manufacture the eco-friendly germanium healing tile 10 according to the present invention, first, a high density fiberboard (HDF) 100 may be prepared.

The high-density fiberboard (HDF; High Density Fiberboard) 100 is a fiberboard formed by mixing finely crushed wood and compressing it at high pressure, and in the present invention, the high-density fiberboard 100 is a high-density fiberboard having a thickness of 2.0 to 2.5mm ( 100) can be used.

The high-density fibreboard (HDF) 100 is a flooring material prepared by combining the advantages of plywood flooring and reinforced flooring, supplementing the disadvantages such as poor durability and scratchability of the plywood flooring, and utilizing the natural texture of wood, but a high-strength surface protection layer. It is designed to be relatively resistant to external impacts by providing a water resistant plywood, and it can exhibit the characteristics of reducing structural deformation due to moisture or temperature.

Germanium is a rare element, a semi-metallic element with a grayish-white gloss, and a semiconductor that has a mysterious pharmacological action. Among the elements present on the earth, germanium is the closest to Qi (氣) and is the strongest element as a mystery element, an element of life, a miracle material. Known as.

Such germanium can be divided into organic germanium (Ge132) and inorganic germanium (Ge32). Only organic germanium can be used in our human body, and organic germanium is an oxygen to eat, and it has been found in modern science as an antioxidant with a lot of hydrogen.

In addition, germanium is an active substance that can supply ionized antioxidants, activate cells, promote growth, convert acidic water into alkaline water that is beneficial to the human body, and emit far-infrared rays to enhance physiological activity and metabolism.

The germanium is known to emit a lot of far-infrared rays, and the far-infrared rays penetrate deep into the skin in the range of 4 to 1000 μm and change into heat, and this absorption action is concentrated in the wavelength range of 5 to 30 μm. When the frequency wavelength is absorbed by the human body, atoms and molecules in the living body cause resonant motion and change into thermal energy, activating each cell and promoting metabolism.

In other words, Germanium (Germanium, Ge) has excellent heat resistance and low thermal expansion characteristics, and is known to emit far-infrared rays higher than other oxides, so it is used in many studies as a far-infrared radiation material. It enters the body to resonate and resonate, and even when ingested, it is discharged out of the body within 20 to 30 hours with various harmful substances, so there is no poisoning or side effects, and it performs functions such as deodorization, anti-mold, dehumidification, air purification, and heat. can do.

The gellite (Ge-lite) is called pozzolan, contains about 2.0ppm germanium and contains a large amount of far-infrared rays and anions, such as volcanic ash, silicate clay, silicate and the like. That is, the gellite emits far-infrared rays equivalent to about 180 times that of loess, promotes plant growth, has a humidity control function, releases negative ions and human body active energy, has a function of blocking harmful electromagnetic waves, and has a deodorizing and sterilizing effect. It also provides the effect of neutralizing heavy metals.

The gellite acts as an adsorbent like the above-described compositions to adsorb and remove harmful components discharged from desulfurized gypsum and cement, block radioactive substances such as radon and electromagnetic waves, and remove odor components such as ammonia.

The biotite has a far-infrared emissivity (94%) that is about three times higher than that of loess, contains a large amount of germanium, and has the effect of removing carcinogens, so it is effective against diseases caused by toxins harmful to the human body, and the action of far-infrared rays is It is known to reach 40-50mm of skin.

In addition, the chemical component of biotite is K(Mg,Fe) ₃ (OH) ₂ ALSi ₃ O ₁₂ , forming a plate shape or impression, and often representing a hexagonal or rhombohedron. In addition, the cleavage is complete on the bottom, and the flakes have elasticity, but are smaller than gold mica, and the color is black, brown black, green black, etc., and the cleaved surface has pearl luster and sometimes has a metallic luster. Hardness is 25~30, and specific gravity is 27~31.

The elvan is a rock belonging to quartz metamorphic rocks among igneous rocks and is characterized by being weathered and fragile. Elvan stone is often kaolinized (to earthen) like white clay used as a raw material for ceramics, and biotite is also almost in the form of iron oxide. Elvan stone is known for its removal of harmful substances and decomposition of heavy metals, mineral elution, water quality control and purification, rich oxygen content, and far-infrared radiation. It's got stuck.

The main components of the elvan stone are silicic anhydride (SiO ₂ ) and aluminum oxide (Al ₂ O ₃ ), and it is composed of 30,000 to 150,000 multi-layered porous materials per 1 cm 3, and has a large specific surface area to adsorb pollutants and heavy metals. It decomposes, and is known to neutralize cement toxicity, antibacterial, insect repellent and strong deodorizing power. Elvan stone, from which more than 40 kinds of minerals are eluted, is known to be effective in metabolism and skin health management, and is also used in cosmetics. Elvan stone is used as a filter for water purifiers by controlling the quality of water and purifying water, and controlling acidic or strong alkaline water to weak alkalinity (pH 7.2~7.4). When elvan stone is immersed in water, COD (chemical oxygen demand) and BOD (biological oxygen demand) are lowered, so it is also capable of preservative action. In addition, it is known that elvan stone is effective in maintaining the freshness of food, increasing taste, and promoting blood circulation and metabolism by radiation of far-infrared rays.

Hanji (Korean Paper, 韓紙) refers to paper made with a unique technique of Korea using the bark of Japanese oak or Samjidak as the main raw material. In addition to being durable and long-lasting, it has excellent heat retention and ventilation properties, and in particular, it has a lifespan of 50~ Compared to Yangji, which causes yellowing and decays in about 100 years, the Hanji has a lifespan of more than 1,000 years, and has a characteristic that a unique pattern stands out and its texture becomes softer as the years go by.
