The heating wire 1 having the above-described structure is coated with ceramics that emit far-infrared rays as a whole, and is coated so as to emit far-infrared rays of different wavelengths, thereby effecting mutual amplification by far-infrared rays of different wavelengths.

That is, the far-infrared ray refers to an infrared ray having a wavelength of 25 占 퐉 or more, that is, a longer wavelength of infrared rays. An infrared ray is a type of electromagnetic wave having a longer wavelength than a red region of a visible ray, and a shorter wavelength is called a far-infrared ray. It is invisible, well absorbed by the material, and characterized by strong resonance and resonance with the organic compound molecules. In addition, light generally has good reflections if its wavelength is short, and it has a property of being absorbed well when it reaches a long object with a long wavelength, so it is strong enough to penetrate, for example, to feel warm when a person's body is exposed to infrared rays. In other words, although it hardly senses a warm aura at 30 ° C water, when you sit at the same temperature, you can feel the warmth because the far infrared rays contained in the sun penetrate deeply into the skin to generate heat. This thermal action helps eliminate the germs that cause various diseases, and it enlarges the capillaries and helps blood circulation and cell tissue production. In addition, when it comes in contact with moisture and protein molecules that make up the cell, it is effective to prevent various diseases such as aging, metabolism promotion, and chronic fatigue by activating the cell tissue by shaking the cell 2,000 times per minute. In addition, it has effects of promoting sweating, relieving pain, removing heavy metals, sleeping, deodorizing, sterilization, prevention of fungus growth, dehumidification, air purification, It is used in various fields such as jjimjilbang. Principle of Far Infrared Rays Dipole changes due to vibration and rotation require most of the electron transitions in the visible and ultraviolet region energy. Infrared radiation is caused mainly by small differences in the energy difference between various vibrations and rotational states. Infrared radiation To absorb or release the molecule, the molecule must produce a change in dipole moment due to vibration and rotational motion. When an infrared ray of the same wavelength is irradiated thereto, the energy of the infrared rays is absorbed by the molecules due to the resonance phenomenon, and the molecule or the molecular end is brought into an excited state. On the other hand, the infrared rays having wavelengths whose natural frequencies do not coincide with each other are transmitted or reflected in the molecules. Under these conditions, the electric field of the radiation can act on the molecules and cause changes in the vibrations and rotational movements of the molecules, and when the frequency of the radiation matches the natural frequencies of the molecules, energy transfer occurs and the amplitude of the molecular vibration changes. As a result, absorption or emission of radiation occurs. Similarly, when an asymmetric molecule rotates around its center of mass, periodic dipole changes occur and interact with radiation. Fundamentals of Far-Infrared Radiation Unless it is absolute, there is a property of converting the heat energy of a substance into the energy of electromagnetic waves and discharging it to the outside. This property is called "heat radiation", but the substance that converts heat energy into energy of electromagnetic wave without energy loss is called "black body", and the radiation intensity and wavelength property by temperature can be obtained by Planck's law. Actually existing objects vary in energy conversion from near black body to low conversion efficiency.

Thus, 1) the far infrared rays known to give vitality (promotion of blood circulation, action of nervous system and meridian system, activation of metabolism, secretion of various hormones and activation of water molecule) If there is a difference in the characteristics of proteins caused by the stimulus, the difference is the effect and effect of the far-infrared rays on the human cells and the difference from the general heat energy. 2) The effect of promoting tissue growth of far infrared rays reveals how to keep DNA, RNA and protein healthy by looking at genetic information of protein.

Far-infrared ceramics is formed by molding inorganic non-metallic raw materials and then treated at high temperature. Among them, since it is used for replacing a part of a living body, it is also called a living body ceramics. Studies have shown that it is more effective at replacing bones and hard tissues than soft tissues.

On the other hand, the effect of far infrared ray farming using ceramics is as follows: 1. Activation of microorganisms by the soil improvement effect increases the permeability and permeability of the soil by activating the soil bacteria to neutralize the soil and neutralize the acidified soil. Alkaline. Also, because it is a porous material capable of surviving microorganisms, it increases the effective microorganisms and promotes recovery of the intelligence. 2. It enhances fertilizer improvement effect and pesticide effective effect. There is no loss of fertilizer because it absorbs and accumulates fertile fertilizer well and feeds nutrients necessary for plant growth. Ceramics are antimicrobial, insecticide and anti-fungal materials even with their own application, which suppresses insect pests and reduces the occurrence of spoilage bacteria in the soil. And it also has the function of the electrodeposition agent, so that the pesticide can be effectively used without using the electrodeposition agent. 3. Prevention and treatment of physiological disorders and trace element deficiency. Ceramics contain about 20 other trace elements such as silicate (Si), aluminum (Al), iron (Fe), calcium (Ca), potassium (K), phosphorus (P), and magnesium To help balance growth. 4. Stimulate the roots of crops and prevent root rot. Ceramic contains a large amount of silicic acid components to straighten the development of myocardium, to make the roots of seedlings vigorous, to facilitate the absorption of water, and to strengthen the stamens of leaves and stems to strengthen the disease tolerance. It purifies water in the soil and removes harmful gas. It suppresses propagation of pathogens, does not mix roots, and strengthens the resistance of plants to diseases.

For example, when the heating wire (1) composed of ceramics is used for agricultural purposes, the far infrared rays of different wavelengths emitted from the heating wire (1) cause bacterial growth of the crop and bacterial or fungal virus And to improve the productivity of the crops by helping to stabilize the stem and root of crops and photosynthesis.

The conductive carbon fibers 20 constituted on the outer periphery of the nickel wire 10 of the heating wire 1 are composed of 99.9% pure carbon fibers as compared with the plane heating elements using ordinary heating wire and carbon black, The thermal calories generated at the same power consumption have about 20% higher heat efficiency.

In addition, far-infrared radiation emissions are very high, which results in a fast heat transfer rate and a uniform heat source reaching the entire crop area. In addition, there is no phenomenon of hardening of heat emitting body or deterioration of heat generation due to heat even over time.

The heating wire (1) of the present invention is formed by covering the inner cover with silicone having excellent heat resistance and woven glass cloth in the form of an X-shaped mesh to reinforce the heating wire (1) Which can prevent damage to the outer coating caused by. By forming the coatings in multiple of the first to third coverings 30, 40 and 50, it is possible to coat the coverings thicker than the inner coverings with heat resistance and resistance to sun exposure to enhance durability, It was adapted to the exposed vinyl house environment, and the safety was improved to minimize the fire and leaked shape due to the hardening phenomenon and the coating crack of general heating wires using PVC coating.

The above description is only one embodiment for implementing a ceramic-coated low-energy high-efficiency functional heating line, and the present invention is not limited to the above-described embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
