Description

A floor paper and the making method functioning block harmful wave}

The present invention relates to a harmful plate blocking plate and a method of manufacturing the same.

More specifically, the present application is a means for obtaining a floor plate having a harmful wave blocking function, but when using a carbon component as a harmful wave blocking functional material, the conductive carbon solution has a harmful wave blocking effect when forming a coating layer or a coating layer with a conductive carbon solution. In addition, the conductive carbon solution coating layer and the mica stone component is a technical idea to take advantage of this phenomenon by confirming the fact that to further increase the blocking effect when forming a laminated structure.

The electromagnetic waves and water waves are closely related to people's daily living and are recognized as harmful waves.

Electromagnetic waves refer to the case where electrons are treated as debris rather than as particles, and it was an experiment conducted by electromagnetic waves that first demonstrated the thought of the wave nature of the material proposed by DeBroy. C.J.Davidson and L.H.Germer proved the reality of DeBroism by discovering that the slow electron beam reflected from the surface of a single crystal exhibits a Raue dot pattern. GP Thompson and PHE loops then revealed that the debychero ring is obtained from a fast electron beam that passes through a polycrystalline thin film. The debro wave wavelength of the electromagnetic wave is λ = h / p (h is Planck's constant, p is electron It is known that the amount of momentum) is given.

There have been reports of adverse effects of electromagnetic waves on the human body, and among the various kinds of electrons, the electromagnetic waves that affect the human body are extremely low frequency (ELF), ultra low frequency (VLF), radio wave (RF) and microwave (microwave). It has been reported that it can affect various diseases such as decreased vision, leukemia, brain tumors, accumulated brain wave disruption in the human body, circulatory abnormalities, male reproductive function, VDP syndrome and eye disease.

Electromagnetic waves emitted from various electrical facilities and electronic products are colorless and odorless and are invisible to our eyes. Moreover, the damage does not appear quickly, and the symptoms accumulate as long as they do not know themselves. It is reported that it causes damage by non-thermal and stimulating effects. Especially, the most damaging effects of thermal action in the living body are on tissues, such as brain cells, which are very weak to heat, and on the reproductive system including the lens and testes of the eye, which have little blood vessel distribution. The nerves, cells, and hormones of our body are controlled by minute electric signals. When the human body is exposed to strong electromagnetic waves, the flow of ions between cells such as sodium and potassium is disturbed, resulting in disability and long-term exposure to electromagnetic waves. It has been announced that being harmful will have a harmful effect on the human body.

In addition, there are surface waters such as ponds and rivers, and groundwater flowing in the ground on the earth where we live, and this groundwater moves through the groundwater layer in permeable soil or rock, which is called water vein. Like the blood vessels of the human body, they are connected like spider webs anywhere in the basement, and when water veins are ditches in the ground where water flows, unusual waves of energy occur at the boundary between water and soil, which are both sides of the ditch. Crazy

The water vein circulates like a blood vein in the human body that flows around the clock for 24 hours, which requires a large amount of water, and the water vein exerts a strong physical force that breaks the surface in order to continuously secure this water. Abnormal waves occur in the process, called vein vein wave or vein wave.

The water vein is irradiated by the vein of the earth's inherent vibration wave (7.5 ㎐) and emits a completely different type of unstable, electromagnetic wave whose waveform is modulated and amplified. It has been found to interfere with sound sleep and interfere with sound sleep.

German physicist Dr. Schumann proved that the earth's natural vibration frequency is 7.8 kHz, which is harmless to the human body, but the water waves coming out of the boundary between the veins and the soil are not these normal frequencies but are caused by the interference of electromagnetic waves. When the natural vibration wave of the earth vibrates up and down by the water vein, the brain wave of the person on the resonance resonates with him, which is as if the screen is shaken when the car passes by next to the TV. Living on this vein is always tiring, headless, poor mental concentration, poor sleep, many dreams, a nap, and a heavy and irritable head. Even though you live in the same place It is reported to receive incense.

In order to block various harmful waves such as electromagnetic waves or water waves, conventionally, a technique of coating gold or silver on a metal or using copper plates in the bottom of a bed for blocking water waves has been conventionally disclosed.

Even if you want to block electromagnetic waves and water waves using other inorganic materials, the manufacturing process is complicated and satisfactory even when using expensive raw materials. The situation was not presenting the results.

Hereinafter, each raw material for implementing the technical idea of the present application will be described.

The chemical component of graphite (graphite) used as a raw material in the present application is C, which is a known substance. Graphite is composed of pure carbon, and is homogeneous with diamond, and is soft with a solidity of 1 or less and a specific gravity of 1.9 to 2.3. It has a fat-like texture, is opaque in black, has a metallic luster, and is a good conductor of electricity.

In addition, the water glass used to obtain the conductive carbon solution herein is a known material made of a concentrated aqueous solution of alkali silicate salt obtained by melting silicon dioxide and alkali, and the water glass has various colors ranging from colorless to white or grayish white. Similar to glass, but a crystal-like mass that dissolves in water to form a syrupy liquid. Also called sodium silicate or soluble glass.

The water glass solution shows strong alkalinity. Alkali is mostly due to Na2 component (K2O in some cases), and the composition of water glass is small amount of Fe2O3 besides Na2OnSiO2 (n = 2 ~ 4). , Moisture is 10 to 30%. Water glass can be obtained by treating a mixture of silica sand and soda ash at 1,300 to 1,500 ° C with a low pressure steam cooker.

Since water glass absorbs carbon dioxide in the air and precipitates gel-like silicic acid, it exhibits strong adhesion, and evaporates water from water glass, or when water glass anhydride and a small amount of water are heated, water glass is formed. It is also used as a raw material for binders and refractory cements.

In addition, the mica stone used as the main functional material in the present application can be selected and used between the biotite and biotite, the biotite belongs to the monoclinic system (單 斜 晶 系), there is a white or off-white pearlescent luster. Originally referred to as the dominant mineral of crystalline schist, especially chorionic schist, today it refers to clay-like fine muscovite formed by hydrothermal action. The chemical composition is almost the same as that of the mica, but in general the potassium K is less than the mica and somewhat more water H 2 O.

Biotite is a mineral belonging to monoclinic system, and its color is black, brownish black, greenish black, and its chemical composition is K (Mg, Fe) 3 (OH) 2AlSi3O12, and its hardness is 2.5 ~ 3.0 and specific gravity is 2.7 ~ 3.1.

The invention was completed by confirming that it is possible to obtain a sheet having a harmful wave blocking function by attaching.

In the present application, most technical configurations for blocking harmful waves in the prior art often use expensive metal copper plates, but the copper plate has a problem in that the copper plate is oxidized and corroded to generate rust that is harmful to the human body when there is moisture. Even when coated with silver, it does not provide any evidence of blocking electromagnetic waves or water waves.In case of blocking electromagnetic waves and water waves using other inorganic materials, the manufacturing process is complicated and satisfactory even when using expensive raw materials. Although it was not in the situation of presenting a reasonable result, the present application includes a conductive carbon coating solution and a functional material of mica, so that it is equipped with the only water wave measurement test apparatus in Korea to check the effect of blocking or attenuating harmful waves.
