Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a method for preparing negative potential alkaline ultrafine molecular cluster water and its application. Background Technology

[0002] With rising living standards and health awareness, people's demand for drinking water has shifted from basic safe drinking to high-quality water with health benefits. Ordinary drinking water typically has larger water molecule clusters, usually measured by nuclear magnetic resonance¹. 7 O-NMR peak widths exceeding 100 Hz result in poor permeability, making it difficult for human cells to absorb efficiently. Furthermore, ordinary water is mostly neutral or weakly acidic, lacking the ability to scavenge free radicals and failing to effectively maintain the body's slightly alkaline internal environment. In contrast, ultrafine molecular cluster water has a smaller molecular cluster structure, significantly improving its bioavailability, enhancing cell membrane permeability, and promoting the exchange of substances between intracellular and extracellular spaces. Simultaneously, ideal healthy water should also possess weak alkalinity and a negative potential, helping to neutralize acidic metabolic products and eliminate harmful free radicals, thus promoting health.

[0003] In the treatment of ordinary water with ultrafine molecular cluster water, magnetic cutting technology is commonly used. While this can achieve molecular cluster refinement and potential adjustment to a certain extent, it is prone to mutual interference when introducing multifunctional components into ultrafine molecular cluster water, resulting in poor stability of core water quality indicators. Furthermore, existing ultrafine molecular cluster water technologies struggle to balance homogeneity with water treatment efficiency, leading to low overall treatment efficiency.

[0004] Chinese Patent Publication No. CN103351042A discloses a method for preparing small molecule cluster water and an apparatus for preparing small molecule cluster water using the method. The method includes: first, placing a metal ring with a discharge hole in the water to be treated; then, applying an alternating magnetic field to the side of the metal ring, causing a discharge phenomenon in the discharge hole of the metal ring, thereby refining large water molecule clusters into smaller clusters. The method also discloses an apparatus for preparing small molecule cluster water using the above method, which includes a non-magnetic container for holding the water to be treated, a metal ring, and an alternating excitation coil. The metal ring is placed inside the non-magnetic container, and the metal ring has a discharge hole. The alternating excitation coil is located outside the non-magnetic container on the side of the metal ring, thereby applying an alternating magnetic field to the side of the metal ring.

[0005] However, the scheme lacks a parameter-effect mapping relationship, and the physicochemical indicators are consistently low. Summary of the Invention

[0006] Therefore, the present invention provides a method for preparing negative potential alkaline ultrafine molecular cluster water and its application, in order to overcome the technical problem of low stability of physicochemical properties of ultrafine molecular cluster water in the prior art.

[0007] To achieve the above objectives, the present invention provides a method for preparing negatively potential alkaline ultrafine molecular cluster water, comprising: Step S1: Determine the particle size of the filter medium based on the first turbidity of the raw water, and determine the first preset filtration pressure in combination with the first turbidity, so as to perform medium filtration and obtain medium-filtered water. Step S2: Based on the second turbidity of the water filtered by the medium, the first preset filtration pressure is dynamically adjusted to perform activated carbon adsorption filtration to obtain purified water with turbidity meeting the standard. Step S3: Add potassium carbonate to the purified water at a preset addition rate, and reduce the addition rate of potassium carbonate during the addition process based on the result that the pH value of the purified water is less than the target threshold, so as to obtain weakly alkaline purified water that meets the preset standard. Step S4: Inject nanobubbles into the weakly alkaline purified water and perform resonance treatment at a preset frequency for a preset resonance duration to obtain resonance-treated water. Step S5: Obtain viscosity data and surface tension data of water molecule clusters in the resonant water at 25°C to jointly determine the first water molecule cluster characteristic value. Based on the first water molecule cluster characteristic value, determine whether the preliminary preparation of water molecule clusters meets the standard. Based on the first water molecule cluster characteristic value, increase the resonance amplitude to re-resonate the substandard resonant water. Step S6: The resonant-treated water is repeatedly magnetically cut using a continuous magnetic field channel formed by alternating polarities to obtain strongly magnetically cut water. Step S7, based on the strong magnetic cutting treatment of water 17 The half-width of the O-NMR peak and the redox potential are used to determine the characteristic value of the second water molecule cluster. Based on the characteristic value of the second water molecule cluster, it is initially determined whether the preparation of the strong magnetic cutting water meets the preset standard. The boiling point and freezing point of the strong magnetic cutting water that is initially determined not to meet the preset standard are verified. Based on the verification results, the magnetic cutting parameters are adjusted. Step S8 involves sterilizing the water treated by strong magnetic cutting to obtain a negative potential alkaline ultrafine molecular cluster water product.

[0008] Further, step S1 includes: Step S11: Obtain the first turbidity of the raw water; Step S12: The product of the ratio of the first turbidity to the reference turbidity and the standard particle size is determined as the filter medium particle size, wherein the standard particle size is 1.0 mm; Step S13: Determine the first preset filtration pressure based on the product of the ratio of the first turbidity to the reference turbidity and the basic filtration pressure, wherein the basic filtration pressure is 0.5 MPa; Step S14: Perform media filtration at the first preset filtration pressure to obtain filtered water.

[0009] Further, in step S2, the dynamic adjustment of the first preset filtration pressure includes: Step S21: Obtain the second turbidity of the water filtered by the medium; Step S22: Calculate the difference between the target turbidity and the second turbidity, and determine the turbidity difference value based on the ratio of the difference to the target turbidity, wherein the target turbidity is 0.1 NTU; Step S23: Compare and analyze the turbidity difference value with a preset turbidity difference threshold, wherein the preset turbidity difference threshold is 0.11; Step S24: Based on the result that the turbidity difference value is less than the preset turbidity difference threshold, determine to continue filtration at the first preset filtration pressure; based on the result that the turbidity difference value is greater than or equal to the preset turbidity difference threshold, determine the second preset filtration pressure, and perform activated carbon adsorption filtration at the second preset pressure to obtain purified water; The second preset pressure is positively correlated with the turbidity difference value, and the second preset pressure is the product of the turbidity difference value and the first preset filtration pressure.

[0010] Furthermore, in step S3, the preset dosing rate is 0.1% to 0.15% of the total weight of the purified water per minute, and the pH value of the purified water is detected once per minute. The dosing rate of potassium carbonate is reduced based on the difference between the measured pH value and the target threshold.

[0011] Further, in step S5, the characteristic value of the first water molecule cluster is calculated by weighted summation of the measured viscosity data and the standard viscosity data, as well as the ratio of the measured surface tension to the standard surface tension. Based on the result that the first water molecule cluster characteristic value is less than the first preset threshold, it is determined that the primary preparation of the water molecule cluster does not meet the preset standard. Based on the difference between the first water molecule cluster characteristic value and the first preset threshold, the resonance frequency increase value is determined, and the resonance-treated water is subjected to resonance treatment again. Based on the result that the first water molecule cluster characteristic value is greater than or equal to the first preset threshold, it is determined that the primary preparation of the water molecule cluster meets the preset standard.

[0012] Furthermore, in step S6, the magnetic field strength increases 3 to 5 times, with each increase being 0.2 to 0.3 T. The water flow velocity in the magnetic field channel is 0.5 m / s to 1.0 m / s. The magnetic cutting process takes 5 to 15 minutes, and the magnetic field direction forms an angle of 80° to 90° with the water flow direction.

[0013] Furthermore, in step S7, the water is treated by the strong magnetic cutting process. 17The characteristic value of the second water molecule cluster was calculated by weighting the half-maximum width (WHM) of O-NMR and the standard half-maximum width (WHM) data, as well as the ratio of the measured redox potential to the standard surface tension.

[0014] Furthermore, in step S7, if the characteristic value of the second water molecule cluster is less than the second preset threshold, it is preliminarily determined that the secondary preparation of the water molecule cluster does not meet the preset standard, and the boiling point and freezing point of the water are verified based on the strong magnetic cutting process. If the characteristic value of the second water molecule cluster is greater than or equal to the first preset threshold, then the primary preparation of the water molecule cluster is determined to meet the preset standard.

[0015] Further, in step S7, the boiling point and freezing point of the water treated by strong magnetic cutting are verified, including: Step S71: Obtain the boiling point and freezing point of the water treated by strong magnetic cutting. Step S72: Based on the verification result that either the boiling point or the freezing point is not within the preset temperature threshold range, it is determined that the water treated by strong magnetic cutting does not meet the characteristics of ultrafine molecular cluster water, and it is determined that magnetic cutting should be performed again; based on the verification result that either the boiling point or the freezing point is within the preset temperature threshold range, it is determined that the secondary molecular cluster water meets the characteristics of ultrafine molecular cluster water, wherein the boiling point threshold is 95℃~98℃ and the freezing point threshold is -8℃~-4℃. Step S73: Based on the difference between the second water molecule cluster characteristic value and the second preset threshold, determine the increase in the number of magnetic field strength increments, and based on the increase, determine the decrease in the magnetic field strength increment.

[0016] On the other hand, the present invention provides an application of negative potential alkaline ultrafine molecular cluster water, including: as a daily beverage for replenishing moisture; as a rinsing water for maintaining oral health; as a care water for improving skin condition; and as a cleaning or atomizing water for relieving eye fatigue.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the molecular clusters of negatively potential alkaline ultrafine water molecules... 17 The O-NMR peak width is 35~42Hz, the molecular clusters are smaller and more stable, and the water quality activity is greater than or equal to 12 months. In addition, the oxidation-reduction potential of negative potential alkaline ultra-fine molecular cluster water is -950mV to -990mV, pH value is 7~9.5, boiling point is 95℃~98℃, and freezing point is -8℃~-4℃, which are significantly different from ordinary drinking water.

[0018] Furthermore, this invention employs a combination of nanobubble-assisted resonance and strong magnetic cutting. First, the hydrogen bond network of water molecules is disrupted through resonance at the same frequency, initially reducing the size of water molecule clusters. During this resonance process, nanobubbles are introduced, and the interfacial tension of the nanobubbles inhibits hydrogen bond recombination. Then, strong magnetic cutting further refines the water molecule clusters, with the magnetic field strength increasing along the water flow direction, achieving precise and uniform refinement of the water molecule clusters. This combination of nanobubble-assisted resonance and increasingly intense magnetic cutting breaks through the conventional mindset of fixed-parameter magnetic cutting, solving the technical challenge of balancing uniformity and efficiency at the process level.

[0019] Furthermore, the small molecule water prepared by this invention 17 O-NMR full width at half maximum (FWHM) is stably less than or equal to 42 Hz, compared to existing ultrafine molecular cluster water... 17 The half-maximum width of the O-NMR peak decreased significantly. This negatively charged alkaline ultracluster water is more easily absorbed by human cells, its negative potential helps to scavenge free radicals, and its alkalinity helps to maintain the slightly alkaline internal environment of the human body.

[0020] Furthermore, ultra-micro molecular clusters have fewer hydrogen bonds and weaker intermolecular forces, making them more likely to penetrate aquaporins on human cell membranes and accelerate the exchange of water between the inside and outside of cells compared to ordinary large molecular clusters of water.

[0021] Furthermore, the negative potential of the ultrafine molecular cluster water in this invention originates from the reduced substances formed during the resonance and magnetic cutting process, such as trace hydrogen atoms and hydroxyl radical scavengers. Through process optimization, the ORP drift is less than or equal to 30mV, maintaining strong reducing properties over a long period of time. After drinking, these reduced substances can undergo redox reactions with reactive oxygen free radicals produced by metabolism in the body, reducing the oxidative damage of free radicals to cellular DNA and proteins, helping to delay cell aging, and reducing oxidative stress-related discomforts such as fatigue accumulation and dull skin.

[0022] Furthermore, ultra-fine molecular clusters can reduce plaque residue through penetrating cleaning. After normalization treatment, the surface tension of ultra-fine molecular cluster water is significantly reduced, much lower than that of ordinary water, and has low dynamic viscosity. This allows it to penetrate deeper into areas that ordinary water cannot reach, such as between teeth and in the gingival sulcus, dissolving and removing food debris and soft plaque. At the same time, the high permeability of water molecule clusters can disrupt the hydrogen bond structure of the plaque biofilm, making plaque easier to detach and reducing the probability of tartar formation. Long-term use can reduce problems such as gingival bleeding and bad breath.

[0023] Furthermore, the ultrafine molecular cluster water in this invention inhibits the growth of pathogenic bacteria by stabilizing a negative potential. The metabolism of oral pathogenic bacteria depends on an oxidative environment, and a strong negative potential can reduce the local redox potential in the oral cavity, disrupt the energy metabolism process of pathogenic bacteria, and inhibit their reproduction.

[0024] Furthermore, the lipid bilayer gap in the stratum corneum is about 0.5 nm. Ultra-micro water molecules with a diameter of less than or equal to 1 nm can penetrate the stratum corneum barrier and reach the dermis to replenish moisture, rather than just staying on the skin surface. At the same time, ultra-micro water molecules can combine with the skin's natural moisturizing factors to form a stable moisture protective film, reduce moisture loss, and keep the skin hydrated for longer.

[0025] Furthermore, skin exposed to ultraviolet radiation and polluted environments is prone to generating free radicals, leading to rough skin, age spots, and wrinkles. The strong negative potential of the ultra-micro molecular cluster water in this invention can directly act on the skin surface, clearing free radicals from the skin's surface and reducing photoaging damage caused by ultraviolet radiation. At the same time, the synergistic effect of deep hydration and anti-oxidation can promote skin cell metabolism, improve dull skin and fine lines, and is especially suitable for sensitive and dry skin as a skin care water, such as for wet compresses or sprays, avoiding the irritation of chemical skin care products.

[0026] Furthermore, the ultrafine molecular cluster water in this invention has a strong negative potential, which can effectively remove harmful free radicals from the surface of the skin and eyes, reduce damage to eye cells caused by oxidative stress, and thus help relieve fatigue and protect vision.

[0027] Furthermore, its ultra-micro molecular cluster structure makes the water molecules smaller, which can penetrate the biological barrier more effectively, helping the moisture and active ingredients to act more effectively on the eye tissue, providing deep hydration and nourishment, and improving eye discomfort caused by dryness.

[0034] Specifically, in step S3, the preset dosing rate is 0.1% to 0.15% of the total weight of the purified water per minute, and the pH value of the purified water is detected once per minute. The dosing rate of potassium carbonate is reduced based on the difference between the measured pH value and the target threshold.

[0035] Specifically, in step S4 of this embodiment, the nanobubbles are gases generated by water electrolysis, consisting of 70% vol oxygen and 30% vol hydrogen. The nanobubbles have a diameter of less than or equal to 200 nm and a concentration of greater than or equal to 106 nanobubbles / mL. They can be prepared using an SPE electrolytic membrane, and the specific preparation method is existing technology, which will not be described in detail here.

[0036] Specifically, in step S5, based on the result that the first water molecule cluster characteristic value is less than the first preset threshold, it is determined that the primary preparation of the water molecule cluster does not meet the preset standard. Based on the difference between the first water molecule cluster characteristic value and the first preset threshold, the resonance frequency increase value is determined, and the resonance-treated water is subjected to resonance treatment again. Based on the result that the first water molecule cluster characteristic value is greater than or equal to the first preset threshold, it is determined that the primary preparation of the water molecule cluster meets the preset standard.

[0037] Specifically, in response to the initial preparation of the water molecule clusters not meeting the preset standard, a resonance treatment is performed again, and the resonance frequency is increased; The increase in resonance frequency is positively correlated with the difference between the characteristic value of the first water molecule cluster and the first preset threshold. The formula for calculating the increase in resonance frequency is: ; in, This represents the increase in resonant frequency. The first preset threshold, The characteristic value of the first water molecule cluster. The preferred value for the standard adjustment of the resonant frequency is [value to be filled in]. .

[0038] Specifically, in step S6, the magnetic field strength increases 3 to 5 times, with each increase being 0.2T to 0.3T. The water flow velocity in the magnetic field channel is 0.5m / s to 1.0m / s. The magnetic cutting process takes 5 to 15 minutes, and the magnetic field direction forms an angle of 80° to 90° with the water flow direction.

[0039] Specifically, in step S7, the water is treated by the strong magnetic cutting process. 17 The characteristic value of the second water molecule cluster was calculated by weighting the half-maximum width (WHM) of O-NMR and the standard half-maximum width (WHM) data, as well as the ratio of the measured redox potential to the standard surface tension.

[0042] Adjusting the magnetic cutting parameters includes increasing the number of magnetic field strength increments while simultaneously reducing each increment.

[0043] Specifically, the increase in the number of magnetic field strength increments is positively correlated with the difference between the characteristic value of the second water molecule cluster and the second preset threshold, and the decrease in the magnitude of each magnetic field strength increment is positively correlated with the increase in the number of magnetic field strength increments.

The physicochemical indicators were qualified, resulting in a negative potential alkaline ultrafine molecular cluster water product. It was packaged in drums using food-grade PC as the packaging material. The factory inspection and testing results are shown in Table 1.

[0050] Example 3: This embodiment provides a method for preparing negatively potential alkaline ultrafine molecular cluster water, which differs from Example 1 in that: The resonant frequency of the same-frequency resonance treatment was 14kHz, the power was 1000W, and the treatment time was 10min to obtain resonant treated water. The remaining steps were the same, and the test results are shown in Table 1.

[0051] Example 4 This embodiment provides a method for preparing negatively potential alkaline ultrafine molecular cluster water, which differs from Example 1 in that: The resonant frequency of the same-frequency resonance treatment was 14kHz, the power was 800W, the magnetic field direction was at an 80° angle to the water flow direction, and the treatment lasted for 15 minutes to obtain resonant treated water. The magnetic field strength for the high-intensity magnetic cutting treatment was gradually increased from 0.5T to 1.4T along the water flow direction, with an increment of 0.3T per segment, for a total of 3 segments. The water flow velocity was 1.0m / s, and the treatment lasted for 5 minutes to obtain the high-intensity magnetically cut water. The remaining steps were the same, and the test results are shown in Table 1.

[0052] Comparative Example 1: This comparative example provides a method for preparing negative potential alkaline ultrafine molecular cluster water, which differs from Example 2 in that the injection of electrolytic nanobubbles in step S4 is omitted; the remaining steps are the same; the test results are shown in Table 1.

[0053] Comparative Example 2: This comparative example provides a method for preparing negative potential alkaline ultrafine molecular cluster water. The difference from Example 2 is that step S6 is modified to have a magnetic field strength of 1T, a water flow velocity of 0.5m / s, and the magnetic field direction is at an 85° angle to the water flow direction. The treatment lasts for 15 minutes to obtain water treated by strong magnetic cutting. The remaining steps are the same. The test results are shown in Table 1.

[0054] Comparative Example 3: This comparative example provides a method for preparing negative potential alkaline ultrafine molecular cluster water. The difference from Example 2 is that in step S6, the angle between the magnetic field direction and the water flow direction is 60°; the other steps are the same; the test results are shown in Table 1.

[0055] Comparative Example 4: This comparative example provides a method for preparing negative potential alkaline ultrafine molecular cluster water. The difference from Example 2 is that only step S6 is performed, and no other steps are performed, to obtain water treated with strong magnetic cutting. The test results are shown in Table 1.

[0056] Table 1. Detection results of negative potential alkaline ultrafine molecular cluster water under different water treatment conditions ; As shown in Table 1, Example 2 is the optimal example. Under the water treatment conditions in Example 2, the negative potential alkaline ultrafine molecular cluster water obtained after treatment has the following ultrafine molecular cluster properties: The smallest half-peak width indicates a smaller molecular cluster structure. In Example 2, the redox potential of the negatively charged alkaline ultrafine molecular cluster water is the strongest.

[0057] A comparison of Examples 1 and 2 shows that appropriately increasing the cutting magnetic field strength and the number of incremental segments is beneficial for reducing the concentration of negatively potential alkaline ultrafine molecular clusters in water. A higher half-maximum width increases its redox potential.

[0058] The negative potential alkaline ultrafine molecular cluster water obtained from Examples 1 to 4 has high stability, and its half-peak width stability can maintain water quality activity for ≥12 months.

[0059] A comparison of Comparative Example 1 and Example 2 shows that, without the injected electrolytic nanobubbles, the water molecule clusters... The half-peak width (WHM) increased significantly, and the stability of the WHM decreased; the redox capacity decreased significantly, the pH value decreased significantly, and the freezing point and boiling point also changed significantly.

[0060] Comparing Comparative Example 2 with Example 2, it can be seen that the water obtained by treating with a single magnetic field strength has a smaller water molecule cluster size. The half-peak width (WHM) increased significantly, the stability of the WHM decreased, the redox capacity decreased significantly, the pH value decreased significantly, and the freezing point and boiling point also changed significantly.

[0061] Comparing Comparative Example 3 with Example 2, it can be seen that changing the angle between the magnetic field direction and the water flow direction affects the water molecule clusters obtained after treatment. The full width at half maximum (FWHM) increased significantly, and its stability decreased. Redox power decreased significantly, and freezing point and boiling point also changed significantly.

[0062] Comparing Comparative Example 4 with Example 2, it can be seen that most small molecule cluster water on the market only undergoes magnetic cutting treatment, and its treatment effect is far lower than that of the present invention. Although it can achieve molecular cluster refinement and potential adjustment to a certain extent, the core water quality indicators are unstable and the product quality is low.

[0063] The cell absorption efficiency of the test examples, Comparative Example 1, and ordinary drinking water was tested, and the results are shown in Table 2: Table 2 Results of cell uptake efficiency test ; As shown in Table 2, the ultra-micro molecular clusters of the present invention have fewer hydrogen bonds and weaker intermolecular forces, making them more likely to penetrate the aquaporins on human cell membranes and accelerate the exchange of water inside and outside the cells compared to ordinary drinking water. Furthermore, the small molecule water prepared by this invention The half-maximum width is stable at ≤42Hz, compared to the conventional ultracluster water in Comparative Example 1. With a significantly reduced half-peak width, this negatively charged alkaline ultra-fine molecular cluster water is more easily absorbed by human cells, making it suitable as a daily beverage for replenishing moisture or as a skin care water for improving skin condition.

[0064] The acid-base regulation and antibacterial ability of Example 1 of the present invention were tested, and the test results are shown in Table 3: Table 3 Results of acid-base regulation and antibacterial ability tests ; As shown in Table 3, the ultrafine molecular cluster water in this invention inhibits the growth of pathogenic bacteria by stabilizing the negative potential. The metabolism of oral pathogenic bacteria depends on the oxidative environment, and a strong negative potential can reduce the local redox potential in the oral cavity, thereby disrupting the energy metabolism process of pathogenic bacteria and inhibiting their reproduction. Significant results have been achieved, and it is suitable for maintaining oral health.

[0065] Based on the standards for purified water in the Chinese Pharmacopoeia and the reference requirements for production water in the Cosmetic Safety Technical Specifications, the products of Examples 1-4 were tested, and the test results are as follows: Table 4. Standard Test Results for Medical Purified Water ; As can be seen from Tables 1 and 4, the purified water of the four examples exhibits excellent water quality characteristics in terms of conductivity, total organic carbon, microbial limits, nitrates, heavy metals, nonvolatile matter, endotoxins, and pH. It meets the standards for purified water in the Chinese Pharmacopoeia and the reference requirements for production water in the Cosmetic Safety Technical Specifications, indicating that the quality of these purified waters is qualified and stable and can be used in pharmaceuticals or cosmetics.

[0066] Negatively potential alkaline ultrafine molecular clusters of water were tested on a test population. The experimental methods and results are as follows: The trial participants were selected from adult volunteers aged 18 to 65 years with mild myopia and visual fatigue, regardless of gender. The participants were randomly assigned to two groups: an experimental group and a control group, with 60 participants in each group.

[0067] Experimental group: Volunteers with myopia and visual fatigue should gently tilt their heads back and look upwards. Use your index finger to pull down the lower eyelid to expose the conjunctival sac. Place a drop of hydrogen-rich water into the conjunctival sac 1-2 cm above the eye, and gently close your eyes for 5 minutes. Use twice daily for 8 consecutive weeks.

[0068] Control group: No products used.

[0069] Before the trial began, each patient's fatigue level, dry eyes, and redness were recorded; a survey of patients' feelings of improvement was conducted; and any adverse events related to product use, such as allergic reactions or skin irritation, were monitored during the trial.

[0070] The international standard E-chart was used to test students' vision. The test method involved the testee standing five meters away from the chart in a seated position. Visual acuity was recorded first for the left eye, then for the right. While testing one eye, the other eye was covered with an eye cover key. The testee's eyes must remain open; they must not squint, look sideways, or tilt their head. The testee identified the "E" optotypes from top to bottom on the chart. Only after a correct answer was the testee moved on to the next optotype. Each optotype took an average of three to five seconds to identify. This continued until the testee could no longer answer, and the visual acuity value next to the last optotype was recorded.

[0071] The experimental results are shown in Table 5: Table 5 Test Indicators and Results of Negative Potential Alkaline Ultrafine Molecular Cluster Water ; After an 8-week experiment, the prevalence of myopia in the control group was 15%, while the prevalence in the experimental group was 5%. Overall, the prevalence of myopia in the experimental group was significantly lower than that in the control group.

[0072] The negative potential alkaline ultrafine molecular cluster water prepared in this embodiment can prevent myopia and delay the growth of vision by relieving eye fatigue and dryness. It can be used as cleaning or atomizing water to relieve eye fatigue.
