Description

Ceramic body having a sterilizing water purification function and its manufacturing method

The present invention relates to a ceramic body having a bactericidal water purification function and a method for manufacturing the same, and more particularly, exhibits radio wave emission and self-discharge effects, thereby enhancing the self-cleaning effect by small-molecule activation of the molecular structure of water as well as various harmful microorganisms. The present invention relates to a ceramic body having a bactericidal purification function and to a method for producing the same, which can effectively prevent the habitation of the same.

Water is an indispensable material for the maintenance of life of all living things including human beings, and is a basic resource that has an important effect on the activities of the entire industry. In recent years, water has been used to improve the quality of living water. The demand is also on the rise.

Generally, water used for living or industrial water is collected from a source and passed through a purification facility, and then supplied to each home and industrial facility through piping, due to insufficient sterilization during purification or increased stagnation time during transportation. Since various harmful nutrients including Legionella bacteria are generated, the hygienic condition of the supply water is very poor, and due to the characteristics of the water pipe network, the water flowing in the pipe is blocked from contact with external air unlike general surface water. Therefore, due to the limitation of the amount of dissolved oxygen contained in the water, the self-cleaning ability is inevitably weakened, there is a problem that the purification effect on various foreign matters are reduced.

Due to the above problems, in the past, various foreign substances were removed by using a filtering method of water purifier as drinking water or industrial water, but this method requires frequent replacement of the filter due to the limitation of the filtration capacity of the filter. There is a problem.

In addition, the water purification method of sterilizing various harmful microorganisms inhabiting water by ozone (O ₃ ) treatment is used, but this may adversely affect the human body due to the irritant of ozone and has a very difficult handling. .

In addition, chemically monomolecular water (H ₂ O) molecules form hydrogen bonds between molecules due to the polarity of hydrogen and oxygen due to the difference in electronegativity. It shows a complex structure.

As such, in the state where water exists as a macromolecular complex structure, the activity is inevitably deteriorated, and thus the washing ability or the self-cleaning ability, which is an inherent function of water itself, is reduced. This is impossible to solve.

The present invention is to solve the above problems, by treating the water by providing a cerammic body calcined by mixing a tourmaline having a phase change characteristic by the permanent electrode and other kinds of ceramic substances and sterilization substances. In this case, a ceramic body having a sterilizing water purification function capable of improving the sterilizing ability or the self-cleaning ability of water and having a sterilizing effect against various harmful bacteria by activating water molecules having a complex structure by electrically small molecules is activated. There is this.

The present invention is mixed with 30 to 40% by weight of tourmaline, 20 to 25% by weight of clay and 40 to 45% by weight of quartz, and then pulverized to 150 to 200mesh, and then 5 to 7% by weight of copper sulfate powder and 2 to 4% by weight of silver nitrate solution. After mixing and molding by adding an appropriate amount of water, and then sufficiently dried at a temperature of 100 to 200 ℃, the temperature is raised to a temperature of 900 to 1000 ℃ at a rate of 4 to 6 ℃ per minute and calcined for 2 to 3 hours A method for producing a ceramic body having a function and the ceramic body are provided.

The tourmaline used in the present invention is a kind of silicate rock, which has a molecular formula of NaMg ₃ Al ₆ B ₃ Si ₆ O ₂₇ (OH, F) ₄ in nature and Na (Fe.Mn) ₃ Al _6. Schole having molecular formula of B ₃ Si ₆ O ₂₇ (OH, F) ₄ and Elbaite having molecular formula of Na (Li · Al) ₃ Al ₆ B ₃ Si ₆ O ₂₇ (OH, F) ₄ There are three series, which have their own permanent electrodes, and when they apply energy such as friction, pressure, or heat from the outside, one end of the crystal is an anode, and the other end of the crystal is a cathode ( cathode), which is more remarkably charged.

When the water molecules having polarity are affected by the electric field formed from the tourmaline, the water molecules become more localized and increase the probability of being dissociated into hydrogen cations (H ⁺ ) and hydroxyl anions (OH ⁻ ). At this time, the hydrogen cation combines with other water molecules to form hydronium (H ₃ O ⁺ ) ions, and the hydroxyl anion also combines with water molecules to form hydroxyl ions (H ₃ O ₂ ⁻ ).

Therefore, a large amount of hydronium ions and hydroxyl ions are present in the water treated by tourmaline. Since these ions are very unstable and highly reactive, they can exhibit excellent self-cleaning ability by oxidizing, reducing, and decomposing heterogeneous molecules. will be.

In addition to charging characteristics, tourmaline has a high rate of far-infrared radiation characteristics, which not only promotes monomolecularization of water molecules by imparting vibration energy to the water molecules present in the complex structure of macromolecules by hydrogen bonding. This will accelerate the dissociation of water molecules.

The tourmaline as described above is produced in rock layers such as natural minerals such as Pagmatite and Metamorphic rock, and the output of these minerals is not only high, but the tourmaline is brittle due to its low hardness. Since the tourmaline alone cannot be molded into a certain form, it is preferable to use it in combination with other materials that can compensate for it in consideration of economical and durability aspects. As described above, clay and quartz were used as the ceramic material capable of promoting dissociation of the bonds between water molecules by far-infrared emission.

The clay used in the present invention is an inorganic mixture containing silicon dioxide, alumina, iron oxide, titanium oxide, and the like, which is known to exhibit excellent far-infrared radiation effect when applied at room temperature or heat. When added and mixed with tourmaline, it can be easily molded into a desired shape.

The tourmaline, clay, and quartz mixture mixed in the above ratio are pulverized into fine particles. When the particle size is 150mesh or less, it is difficult for each foreign matter to be mixed in an even distribution, and it is not necessary to finely crush it to exceed the particle size of 200mesh. .

An inorganic fungicide is mixed with the tourmaline, clay, and quartz mixed with it. The silver nitrate used in the present invention may be converted into a form of silver oxide by heat during firing to exhibit sterilization properties, and the mixing ratio thereof may be 2 parts by weight or less. In this case, it is difficult to obtain the desired sterilization effect, and when it is added in excess of 4 parts by weight, not only the production cost increases but also the silver nitrate which is not converted to silver oxide remains after the calcination is completed. Most preferably mixed in parts by weight.

Copper sulfate added with the silver nitrate as described above is added to maintain the adhesion strength after calcination of the silver nitrate oxide is less than 3% by weight it is difficult to obtain the desired adhesion strength retention effect, it is necessary to add more than 7% by weight There is no.

When the dough is added by adding an appropriate amount of water to the tourmaline, clay, quartz and inorganic fungicide mixtures mixed at the ratio as described above, and then molded into a suitable shape such as spherical or cubic, and then fired, Ceramides are prepared.

The ceramic body of the present invention finally exhibits sufficient strength through a process of firing at a high temperature of 900 to 1000 ° C., but since the molded body is easily destroyed due to sudden high heat, a gradual temperature increase from low temperature is required during firing. Shall be.

For this reason, as a preliminary process before firing, the molded body should be kept at 100 to 200 ° C. for a sufficient time to sufficiently dry excess moisture contained in the molded body, which is formed by sudden evaporation of moisture due to overheating applied to the molded body during firing. This is to prevent cracks and breakage.

The dried product is heat-treated at a temperature of 1000 ° C. or lower, preferably 900 to 1000 ° C. for 2 to 3 hours to remove all moisture remaining in the molded body and to uniformly burn the inside and the outside of the molded body. In this case, it is preferable to maintain a temperature increase rate of 4 to 6 ℃ per minute to prevent the molded body from being destroyed by the sudden application of high heat.

In the state of filling the inside of the tubular body prepared by the above-described process with the mesh at both ends by using a coupling means such as a flange to the pipe installed in the general home and industrial facilities to the water to the water treatment. In this case, as the ceraxic mixture vibrates due to the flow pressure of the water, electrons are generated to promote dissociation of water molecules, and active oxygen (O ₂ ⁻ ) generated in this process reacts with water molecules to produce hydrogen peroxide. (H ₂ O ₂ ) is produced, and hydrogen peroxide reacts with ammonia and hydrogen emulsion, which are malodorous components, as shown in the following Reaction Scheme 1 and Scheme 2, thereby showing a deodorizing effect.

2NH ₃ + 3H ₂ O ₂ → N ₂ + 6H ₂ O

H ₂ S + H ₂ O ₂ → 3H ₂ O + S

At this time, the size of the molded article can be arbitrarily determined, and as the size of the molded article becomes smaller, the contact area with water increases, so that the activation effect of water can be increased. Therefore, it is desirable to appropriately determine the size of the molded body.

Hereinafter, the present invention will be described in more detail with reference to Examples and Experimental Examples.

EXAMPLE

3 kg of tourmaline, 2 kg of clay, and 4 kg of quartz were put into a grinder and pulverized to a particle size of 150 mesh through powder and 200 mesh unbreakable powder. , And evenly sprayed with an appropriate amount of water, and then molded into a sphere having a particle diameter of 10 mm in the pen.

The molded product thus prepared was placed in a heating furnace and sufficiently dried in a state of maintaining a temperature of 150 ± 10 ° C., and then calcined for about 3 hours while being heated up to a temperature of 950 ± 10 ° C. at a rate of 5 ° C. per minute.

[Sterilization test example]

The test strain was prepared by culturing Staphylococcus aureus, Escherichia coli, and Legionilla pneumophila, and the ceracic bodies prepared from the above examples were filled in the inner tube with a network at both ends. In the state, the preparation water in which the Staphylococcus aureus and Escherichia coli group were cultured was observed once, and the preparation water in which Legionilla pneumophila was cultured was repeated three times, and then observed the growth of the strain present in the treated water. It is shown in Table 1 below.

As shown in the results of Table 1, the treated water was found to be 76.7% and 80% of the Staphylococcus aureus and Escherichia coli group in one treatment with the ceramic body of the present invention, respectively, compared to the preparation water. In particular, in the case of Legionella pneumophila, as shown in FIG. 1, the culture water of 1.3 × 10 ³ CFU / ml was shown in the case of the preparation water, but the result after one pass shown in FIG. 2 was 1.0 × 10 ² CFU / ml. 92% was negative as 7.2 × 10 CFU / ml after 2 passes as shown in FIG. 3 and 94% was negative as 0 CFU / ml after 3 passes as shown in FIG. 4. It was found that the sieve showed very good bactericidal properties.

As can be seen from the above description, the present invention not only improves the self-cleaning ability of water while activating the water molecules having a complex structure by electromagnetically monomolecularly, but also survives bacteria due to the solidification of simple proteins. It is a useful invention to provide a method for producing a cerak mix having a sterilizing water purification function that can exhibit excellent sterilizing effect against various harmful bacteria inhabiting in water by reducing its ability.
