Description

Material for blocking water veins and electromagnetic waves and a device comprising the same {Material for blocking water vein wave and electromagnetic wave and device including the same}

The present invention relates to a novel material that blocks water and electromagnetic waves derived from minerals, and specifically, water and electromagnetic wave blocking materials for preventing various damages by water and electromagnetic waves, and water-wave and electromagnetic wave blocking devices including the same. It relates to a water wave and electromagnetic wave blocking method.

A vein refers to a certain amount of water flowing underneath the surface of the earth, that is, underground to form a vein. The vein is an indispensable environment for the circulation of water below the surface of the earth. It can be produced or destroyed by changes in the strata. Water veins exist as wide as human blood vessels and are constantly flowing, and small water can gather to form large water. However, the direction of movement of underground veins flows from a high place to a low place, as opposed to gravity, like water on the ground. It can exist, and most subterranean veins can flow deep into the ocean. Groundwater that flows underground like blood vessels of the human body emits a strong kind of wavelength that continuously destroys the earth's surface as it flows along the veins like the blood veins in the human body. Such water wave is widely known to be harmful to the human body. The water veins can break the ground and destroy rocks to get water from the ground, break down the rice paddies, and the water from the ground can continue to emit a constant water wave continuously. A vein wave can be seen as a kind of electromagnetic wave that radiates energy to earth's surface during the tectonic fluctuation or nuclear fission as it passes through the veins in the underground rock and radiates to the surface after being generated underground. Can be strong. Here, the water wave is a vertical wave that acts vertically and has a destructive force vertically, which causes structural cracks in buildings or roads where water veins pass by.

On the other hand, the water can be detected using the elrod (L-ROD) or the probe, it can be avoided by the water to avoid the effect of the water wave to people living inside the building by avoiding the water wave. However, even if the building is constructed by avoiding the water vein, when the water vein is changed to be adjacent to or pass through the water, there is a problem in that the water wave transmitted from the water veil cannot be blocked.

In addition, the water vein will cause a variety of plants and animals and various physical and mental diseases. In particular, because the water wave is a kind of electromagnetic wave, when the electromagnetic wave is transmitted to the human body, it causes disturbance of blood circulation, disturbance of brain wave, abnormal secretion of human hormone, weakening of resistance to cancer, change of calcium movement of cell, change of biorhythm, For a long time, the body and mind of the human body become unstable and suffer from various diseases, and it is known to cause various diseases such as insomnia and neuralgia.

Electromagnetic wave is a form of energy generated by the use of electricity and is a synthesized wave of an electric field and a magnetic field. Electromagnetic waves are emitted from the electric machinery and equipment in use around us. Electric wave is the space where the force of electricity is vertical, expressed in volts per meter (V / m), and magnetic field wave is the space where the force is horizontal. Is usually expressed in milligaus (mG). Electromagnetic waves are classified into household power frequency, ultra low frequency, low frequency, communication frequency, and microwave according to frequency (the number of vibrations per second), and the frequency increases in the order of infrared rays, visible rays, ultraviolet rays, X rays, and gamma rays. Ultra-low and low-frequency electric fields and magnetic fields are known to be prone to development of diseases by breaking body temperature changes and biorhythms when exposed to human body for a long time.Men's sperm count is reduced and women are the cause of menstrual irregularities and birth defects. Some studies have shown that it can. In addition, the harmful effects of electromagnetic waves are being discovered one after another, which can cause brain tumors in severe cases. Although no accurate analysis of the cause of electromagnetic waves harmful to the human body has been made, it is known that it is beneficial to the human body to keep it away from the electromagnetic wave source.

Conventionally, materials using non-ferrous metals, such as copper and aluminum, have been used to block water waves and electromagnetic waves. However, the effects of water waves and electromagnetic waves are insignificant, and their effects are lowered during use, and they are manufactured from copper plates or aluminum plates. The implementation is limited by factors such as a price increase on the manufacturing cost, and the non-ferrous metals have a disadvantage in that it is difficult to commercialize because of the large weight. Therefore, in order to prevent damage caused by the water wave and the electromagnetic wave, the need for a material that can block the water wave and the electromagnetic wave is emerging.
