Description
Technical Field
The invention relates to the field of photo-, magneto-and electric effect induced dissociation of water molecules to produce OH-、H+And the technical field of new materials of terahertz waves, in particular to a preparation method of a magneto-optical crystal composite material (magneto-optical crystal for short) and an ecological sponge product.
Background
Generally, normal people require about 130 million negative ions per day, while our environments in homes, offices, entertainment venues, public places, compartments, etc. can only provide about 2-20 million negative ions per person. PM (particulate matter)2 .5The sharp rise of environmental pollution is more direct and causes a certain degree of destructive power and negative influence on society: the magnetoelectric network generated by computers, mobile phones and other electronic finished products in cities leads the positive ion content in cities to be continuously increased; the large-scale industrial decoration enables various dangerous chemical toxins to be inhaled into the human body along with air, thereby seriously damaging the immune system of the human body and even causing various diseases, such as: high incidence of malignant tumor, cardiovascular and cerebrovascular diseases, hematopathy, juvenile myopia, sub-health, etc.; the positive air ion content is also exacerbated by acidic carbon dioxide excreted by people in schools, homes, and places where people congregate in public. The air negative ions are added in a certain space, so that the environmental properties of the space environment can be effectively improved. The relationship between the anion concentration and the human health degree was compared in papers published by Taiwan university of Zhongshan.
Table of effect of anion concentration on human health degree
| Concentration of environmental site (units/cm)3） | Degree of human health |
| Forest waterfall 10000- | The human body has natural healing force |
| 5000-class 10000 for high seaside | Sterilizing and reducing disease infection |
| 1000-fold 5000-fold medicinal material for rural field | Enhancing immunity and antibacterial effect |
| City park 400- | Reluctant maintenance of human health |
| Street greenbelt 200- "Yihai 400 | Reducing human immunity |
| City room 100 | Inducing physiological disturbance, headache, insomnia, etc |
| 40-50 building offices | Inducing physiological disturbance, headache, insomnia, etc |
| Industrial development area 0 | Is prone to various diseases |
From the above table, it can be found that the concentration of negative ions has a great relationship with the degree of human health. World health organization regulations: the standard concentration of negative ions in the fresh air is not less than 1000-1500 negative ions per cubic centimeter of air per second.
Therefore, artificial negative ions are currently widely used in various aspects of life, with the purpose of creating a good ecological space and improving living environment. However, these negative ion products have a drawback in terms of safety as analyzed from a technical point of view. The summary is four points: firstly, pollution particles with certain polarity are generated and are called heavy ions; secondly, harmful aggregates are generated; thirdly, generating ozone; fourthly, electric radiation is generated or the radiation exceeds the standard. Most of these techniques generate negative ions by electron emission, as the mechanism. Only the negative ions are generated from the self-polarizing material, and there is a problem that the generation amount is limited.
And another way of generating negative ions exists in nature-dissociation of water molecules. Dissociation of water molecules to produce OH-And H+。
Hydroxyl ion (OH)-) Is one of the air anions, which is determined to be OH according to the International Union of geodetics and geophysics, the Commission on the atmospheric pressure-（H2O）n、O2 -（H2O) n and CO4 -（H2O) n. Wherein OH is-（H2One of the ways of generating O) n is the dissociation of water molecules. OH with appropriate concentration in air-And H+Has beneficial effects on human health, long life and ecological environment. Seashore, lake, near waterfall and near jet ponds are the most abundant. Therefore, when people enter the field, the brain is fresh, and the breath is smooth and refreshing.
Dissociation at water molecules generates hydroxide ions (OH)-) While producing hydrogen (H)+). The hydrogen element is listed in the first place of the periodic table of chemical elements and is the smallest, lightest and largest element in the universe. 90% of elements in the universe and 63% of elements in the human body are hydrogen. The water in nature is the hydrogen reservoir. The hydrogen and the oxygen are combined into water, and the life in the nature is inoculated. It can be seen that hydrogen is important to the life of everything on earth. Hydrogen is not only a clean energy source, but is also the most basic antioxidant substance for all life on earth. Hydrogen (H)2) Is a new hairThe present bio-gas signal molecule. Since 2007, about H2The physiological regulation activity and the signal transduction function of the compound are widely concerned, and a new subject for researching the biological effect and the molecular mechanism of the hydrogen, namely the hydrogen biology, is gradually formed. In medicine, H was found by various animal model studies and partial clinical trials2Has antioxidant, antiinflammatory and anti-apoptotic effects, and is characterized by2Has ideal positive effects on ischemia/reperfusion, acute tissue ischemic diseases based on inflammation and chronic degenerative diseases (such as Parkinson's disease, Alzheimer disease, atherosclerosis and other oxidative stress related diseases).
Terahertz waves (THz). Terahertz waves, known as "life rays," are electromagnetic waves of "light" energy, having a wavelength of between 3 μm and 3000 μm, a frequency of 0.1-10THz, between microwave and infrared. Terahertz waves are quantum waves that not only possess the same straightness as light, but also have similar penetrability and absorptivity to electric waves. Most importantly, the terahertz wave has low photon energy, only a few millielectron volts, emits 1/135 with the intensity of only X rays, and cannot cause ionizing radiation damage to cells. In nature, carbon (C) and water (H)2O), carbon monoxide (CO), nitrogen (N)2) Oxygen (O)2) And so on, a large number of substances are emitting terahertz waves. Terahertz waves are generally considered to coincide with the wave frequency of the human body itself.
Disclosure of Invention
The photomagnetic crystal provided by the invention can absorb natural energy of sunlight, temperature, vibration and the like in the nature under the normal state at normal temperature, and permanently induces the water molecules in the air to dissociate to generate high-concentration OH-、H+And preparing the ecological sponge product by adding the terahertz waves and the magneto-optical crystals.
The first technical problem to be solved by the present invention is to provide a method for producing OH by simple reaction-、H+And a magneto-optical crystal of terahertz wave.
The invention adopts vacuum heat treatment and nano treatment process to design and dope various specific substances (impurities) so as to mix the materialsThe material crystal lattice is changed in arrangement to prepare a new crystal material, namely a photomagnetic crystal. Under the normal state of normal temperature, the photomagnetic crystal absorbs natural energy of natural sunshine, temperature, vibration and the like, and under the premise of higher safety, through the action of a photomagnetic field, single crystal polarization, resonance effect, superposition effect and the like, the photomagnetic crystal permanently induces the dissociation of water molecules in air and water to generate high-concentration OH-、H+And terahertz waves.
The technical scheme adopted by the invention is as follows:
the magneto-optical crystal adopts the following raw materials in percentage by weight:
55-65 parts of kaolin, 15-20 parts of nano rare earth mineral powder, 8-12 parts of nano titanium dioxide, 1-2 parts of nano zinc oxide, 5-10 parts of ruby powder, 3-5 parts of anion powder and a proper amount of powder dispersant.
The preparation steps are as follows:
(1) the components are fully mixed to prepare a mixed material.
(2) Vacuum calcining the mixed material to obtain a photomagnetic crystal blank; the calcining temperature of the vacuum calcining is 500-800 ℃, the calcining time is 20-30 min, and the vacuum is 400 Pa.
(3) And cooling the blank, performing nanocrystallization treatment, crushing and grinding to 3000-5000 meshes to obtain the magneto-optical crystal body material, and finishing the magneto-optical crystal preparation.
The kaolin in the photomagnetic crystal of the invention becomes a wave frequency modulator and plays a role of a molecular sieve at the same time. The doped (doped) kaolin is calcined, the change and arrangement of the crystal structure change the energy band structure, and the forbidden band prevents the terahertz wave frequency from entering the material and being reflected out. On the other hand, due to its pyroelectricity and piezoelectricity. The polar ions of the electromagnetic wave vibrate at the equilibrium position to cause the dipole moment to change, thereby generating the electromagnetic radiation of far infrared wave band. The additive is added according to a certain proportion, so that free ions, impurity ions, ionic substances, impurities, two-phonon and three-phonon of the additive resonate to generate electromagnetic waves, ionic bond polarity vibration of organic and inorganic molecule cross chains is driven, and a strong amplitude broadband is generated. The wavelength of the far infrared rays radiated by the photomagnetic crystal composite material is 2-18 mu m in the range of terahertz waves, and the radiation power emission density is 0.04 w/cm2Slightly higher, it is highly harmonious with the human body and can be absorbed by the human body; the kaolin-based mineral crystals are mainly composed of tetrahedra and octahedra, wherein the tetrahedra are linked in two-dimensional directions in a manner sharing a vertex angle to form a hexagonal arrangement of mesh layers. The structure of the material plays a role of a molecular sieve, so that the ion exchange property and the catalytic performance of the photomagnetic crystal are improved. The water molecule dissociation efficiency is improved by mixing the water molecule with the anion powder and the nano rare earth mineral powder;
the metal oxide in the nanometer rare earth mineral powder in the magneto-optical crystal is a magnetizer of the magneto-optical crystal. The nanometer rare earth mineral powder has strong light absorption capacity and high conversion efficiency; the emission wavelength distribution area is wide; stable physical and chemical properties, high temperature resistance, and can bear the actions of high-power electron beams, high-energy radiation, strong ultraviolet light and the like. The lanthanide metal oxide in the rare earth mineral powder plays a role of a magnetic field in the photomagnetic crystal. The electric field strength of the negative ion powder represented by tourmaline can be evaluated by electric polarization strength, and the larger the electric polarization strength is, the stronger the ability to dissociate water molecules is. Under the action of the photo-magnetic field, the electric polarization intensity of the single crystal of the negative ion powder and other materials under the action of the photo-magnetic field is greatly improved compared with that of the unmagnetized single crystal, so that the negative ion powder and other materials are dissociated from water molecules H+And OH-The ability of (a) to be enhanced.
The nano titanium dioxide and zinc oxide in the magneto-optical crystal are ultraviolet absorbers. The ultraviolet ray is divided into three wave bands of UVA, UVB and UVC. UVC is completely absorbed by the earth's atmosphere and is not considered. UVB is only partially absorbed by the atmospheric ozone layer, whereas UVA is not absorbed by the atmospheric air. The ultraviolet rays reaching the earth surface mainly consist of UVA (more than or equal to 90 percent) and UVB (less than or equal to 10 percent). Titanium dioxide absorbs UVB more efficiently and less efficiently for UVA wavelengths above 350 nm. Zinc oxide absorbs UVB weakly but absorbs UVA of 350nm or more, as compared with titanium dioxide, and has a maximum uv-cut wavelength of about 370 nm. According to the characteristic that titanium dioxide and zinc oxide have different ultraviolet absorption degrees in different wave bands. The mixed formula of titanium dioxide and zinc oxide is adopted, so that the photomagnetic crystal can absorb ultraviolet rays maximally.
The negative ion powder in the magneto-optical crystal of the inventionIs the initiator of the dissociation of water molecules. Is one or more of nanometer rare earth lanthanide metal oxide, tourmaline, medical stone, mirabilite, coral fossil, opal, serpentine, beidellite, King's stone and shell powder. Dissociation of water molecules induces electrolysis of water from spontaneous polarization effects: h2O electrolysis of OH-+H+Hydrogen ions get electrons from weak current between negative ion powder electrodes; 2H++2e→H2℃,. hydroxyl ions are combined with water molecules to form air negative ions; OH group-+nH2O→OH-(H2O)n。
The ruby powder of the magneto-optical crystal is an activator. The main component of the ruby powder is aluminum oxide. The aluminum oxide has strong adsorption capacity and water absorption, and becomes a photomagnetic crystal water molecule supply source to supplement the photomagnetic crystal water molecules; has ion conduction capability to improve the photo-magnetic crystal photo-magnetization activity.
The induction multiplication of the photomagnetic crystal is realized. The increase of the specific surface area of the photomagnetic crystal double layer or multiple layers generates the superposition effect to enable OH-And H+Multiplication is carried out. Dissociated OH-And meanwhile, the water molecule is used as a far infrared emitter, and the dissociation of the water molecule is further induced by the same-frequency resonance.
The induction function of the magneto-optical crystal of the invention has no side effect. Photo-magnetic crystal induces dissociation of water molecules into H+And OH-The terahertz wave does not generate by-products harmful to human bodies, and the resonance effect, the polarization effect and the magnetization effect of the terahertz wave induce the dissociation of water molecules, so that the terahertz wave is completely natural and safe; the photomagnetic crystal material can also be combined with sponge products and other carriers and spaces or water bodies not limited to the sponge products to form a complete dissociated water molecule to generate H+And OH-And an ecosystem of terahertz waves.
The invention carries out nano treatment on the magneto-optical crystal to reach the safety of 3000-5000 meshes. Although the higher the nano-crystallization degree of the photomagnetic crystal is, the higher the efficiency is, the unknown risk factors exist when the photomagnetic crystal reaches the nano level and can directly enter human cells. Therefore, it is desirable to control it to the micrometer level from the security point of view.
