Technical Field

The invention relates to the technical field of ceramic materials, in particular to a terahertz wave resonance ceramic material, a preparation method thereof and a water purifier applying the terahertz wave resonance ceramic material.

Background

THz waves (terahertz waves) have been formally named since the middle and late 80 s of the last century, and scientists will collectively refer to far-infrared rays. Terahertz waves are electromagnetic waves with a frequency in the range of 0.1THz to 10THz, and have a wavelength in the range of approximately 0.03 to 3mm, which is between microwave and infrared. The method is in a transition region from a macroscopic classical theory to a microscopic quantum theory and from electronics to photonics. It is higher than microwave in frequency and lower than infrared; the energy magnitude is then between electrons and photons. Scientific research finds that non-interference terahertz waves in the universe and nature are one kind of energy waves, namely the terahertz waves are located between light and radio waves, have the frequency of about 1THZ (the 12 th power of 10 at 1 terahertz), and have the characteristics of two aspects of waves and particles (wave particle bidirectionality); the wavelength is 3 μm to 1000 μm, and the range of the included wavelength is extremely wide. The wavelength range of the far infrared light wave is 3-12 mu m, and the far infrared light wave is only a part of natural terahertz waves and a part (accounting for about 10% of the field) at the beginning of the light wave. Natural terahertz light waves are generated by the thermal vibration of crystalline lattices of organic molecules in natural minerals, inorganic substances, life and living organisms and living bodies. However, the terahertz waves emitted by these natural substances have low average emissivity and emit a small amount of radiation.

Compared with artificial terahertz waves, the natural terahertz wave energy has the advantages that the radiation amount is only about 1 ten-thousandth of 4, and is extremely weak, but the types of the wavelengths contained in the natural terahertz wave energy are infinite and wide, all life activities in nature are covered in the natural terahertz wave energy, and various physical properties of substances are determined.

From the electromagnetic spectrum, the terahertz wave is between millimeter waves and infrared light, the terahertz wave is overlapped with the millimeter waves which mainly depend on the development of electronics in a long wave band, and is overlapped with the infrared light which mainly depends on the development of photonics in a short wave band, so that the visible terahertz wave is in a special electromagnetic wave band which is in transition from macroscopic electronics to microscopic photonics. The terahertz wave is weaker than infrared ray in intensity, but completely resonates with a human macromolecular structure.

Research shows that the substance which is most likely to resonate (absorb) with the terahertz wave is water, and meanwhile, the substance which is likely to resonate has better radiation effect. Water has physical properties of absorbing and storing lattice vibration (hydrogen bonding vibration) and rotational vibration in its molecular structure. Through computer analysis, people find for the first time that water can absorb all terahertz waves within the wavelength range of 10-100 Hz, and store the terahertz waves. Although there is H2O as the carrier, the frequency is also changed by these movements, since the water will vibrate and will rotate itself.

Cellular ecological healthy water is awarded according to the 2003 year world nobel chemical prize: american scientists, doctor of the medical college at hopkins university, professor in biochemistry and medicine, peter alogrel "cell membrane water channel discovery" and american scientists, professor in neurobiology and biophysics at rockfiler university, rodrek, maijinnong "structure and mechanism of cell membrane ion channels", and world nobel medical awarder in 1963: haxili et al, which discovered that ions can pass from one nerve cell to another nerve cell. The cell and the surrounding environment exchange information, substances and energy, and the core of the method is to realize the life function of the cell by means of the entrance and exit of water molecules and various ions in a cell membrane channel. And the life information of one cell is transmitted to another cell, so that the genetic multiplication of the cell is realized. Water in nature does not exist in the form of a single water molecule (H2O), but a plurality of water molecules are aggregated together through hydrogen bond action to form a water molecule cluster, which is commonly called as a water molecule group in China. The water molecule groups are divided into large molecule groups and small molecule groups. The small water molecular groups are easy to be absorbed by human cells, so that the physiological function of the water is reflected to be strong, and the water with strong physiological function is also called as active water. The water with the macromolecular group structure is a random and amorphous chain-shaped coil, the dissolving capacity and the permeability of the water are very low, the water is difficult to enter human cells, only the water with the macromolecular group structure similar to liquid crystal and with the short chain-shaped structure can easily enter the cells to participate in life metabolism activities, and various ions are brought to cell membrane ion channels to enter the cells. In addition, the water molecule group is small, the activity is high, and the water is drunk well; and the larger the water molecular group, the smaller the activity, so the drinking is not good.

At present, the so-called small molecular group water production method on the market generally utilizes mineral electrolyzed water (such as mineral matters like tourmaline and the like) and magnetization equipment to treat water and the like to enable large molecular group water to be decomposed into 5-8 small molecular group water from 15-20 water molecules, and because the small molecular group water obtained by the method does not substantially change the arrangement problem of the water molecule structure, although the water is treated by a static magnetic field or a variable magnetic field, or mineral electrolyzed treatment and the like, the physicochemical property of the water can be changed into 5-8 small molecular group water, and the property can be kept for hours, but related researches show that the small molecular group water obtained by the modes of electrolysis or magnetization and the like can be changed according to the temperature, environment, time, ion concentration, pH value, and energy applied from the outside, such as electric field, magnetic field, sound wave, oxygen, carbon dioxide, carbon, the hydrogen bond content in water increases slightly by radiation, infrared rays, pressure, and the like, and the cluster reduction of water increases.

Therefore, research and development of new materials for terahertz wave resonance and production of relatively stable small molecular water beneficial to human health are urgent problems to be solved in the prior art.

The water after the first three-stage filtration enters a filter element filled with the terahertz wave resonance antibacterial hydrogen-rich ceramic material. The terahertz wave resonance antibacterial hydrogen-rich ceramic material adopts a material with a frequency (12 th power Hz with 10 vibration frequency) corresponding to water molecules, can resonate with the water molecules to activate the water quality, and rearranges the structure of the water molecules, so that the healthy water closer to a natural water source can be produced. Due to the addition of the nano antibacterial hydrogen-rich component, the water contains a large amount of hydrogen molecules. In 7 months 2007, the student of Japan medical university reports "Natural medicine", and the animal breathes 2% of hydrogen to effectively eliminate the free radicals. Therefore, the hydrogen molecules in the water purified by the water purifier can further remove excessive active oxygen (oxygen free radical) in the body, and can also purify the blood, so that the blood is smooth, the metabolism is vigorous, various diseases are prevented, and the health of the human body is improved. Through the nano-scale antibacterial filter material, the bacterial harmful substances in water can be effectively inhibited, a good antibacterial effect is achieved, and the direct drinking of the discharged water is realized.

In order to verify the effects of the present invention, the following experiments were performed to verify the effects of the present invention.

1. Determination of the size of Water molecular groups

Water molecule groups are difficult to detect directly by conventional means. The current method of detecting the size of water molecular groups is by "nuclear magnetic resonance" NMR (17O-NMR technique), which measures the size of water molecular groups by measuring the half-width of the oscillation frequency of the water (expressed in hertz Hz). When the cluster structure of water is larger, the exchange of spin states between oxygen nuclei or hydrogen nuclei and adjacent magnetic nuclei is faster, the time required to restore to an equilibrium state is shorter, and the half width of a spectral line is wider. Conversely, the smaller the cluster structure of water, the narrower the half-width. That is, a larger Hz value indicates a larger water molecule group, and a smaller Hz value indicates a smaller water molecule group.

The raw materials in the first embodiment of the invention are purified by using the terahertz wave resonance ceramic material prepared by the method of the invention as a filter element, and the water is sent to a BRUKER AVANCEDMX 500 nuclear magnetic resonance instrument of Shanghai Compound denier university to measure the half-width of the vibration frequency compared with the comparative examples 1-8, so as to obtain the experimental data in the following table 5, and fig. 3 and 4.

Water purified by using the terahertz wave resonance ceramic material as a filter element (hereinafter referred to as purified water of the invention) is divided into three groups, and the three groups are respectively detected: the detection sample 1 is a water sample purified within one day, and the detection sample 2 is a water sample obtained by heating purified water to 100 ℃ and cooling the water sample to normal temperature. The detection sample 3 is a water sample which is tested on the 8 th day after purification. The three sets of samples were subjected to measurement of half width of vibration frequency.

The experimental data obtained by the detection are shown in table 6 below, fig. 7 and fig. 8.
