1 is a flow chart of a process for producing EM yellow loess bricks according to the present invention

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a method for controlling the humidity of buildings in a building built of yellow clay bricks and a method of controlling the humidity of air in buildings built with yellow bricks by using the microorganisms (EM) and loess for making dough, adding rice husk powder, sericite powder and fly ash to the dough, (EN) The present invention relates to a method for manufacturing an EM loess brick, which is capable of imparting excellent effects to clean, far infrared rays, antibacterial, deodorizing, soundproofing, sound absorption and strength improvement functions. S2, a loess kneading step S3, a mixing kneading step S4, a loess brick molding step S5 and a drying step S6.

In recent years, as the perception of well-being has been spreading throughout society as a measure of happiness, a life that maintains healthy mind and body rather than material value or honor, Interest is growing.

These loess are the most beneficial rays of life for all life, and our ancestors used them to make houses and land from ancient times, which has a refreshing energy that gives warmth to the cold energy of the night and coolness to the warmer day It is because of the characteristics of loess.

In comparison with the EM yellow clay bricks produced according to the present invention, the yellow clay has a very excellent effect of absorbing moisture when the humidity is high and controlling the humidity to let the moisture into the air when the indoor is dry have. Far infrared rays emitted from loess have an effect of eliminating bacteria and fungi because they are excellent in antibiotic action and antibacterial action due to an excellent adsorption power as well as an air cleaning effect by anionizing a cation which is a cause of unpleasant odor including a smell of tobacco In addition, the action of the rich minerals contained in the loess has the effect of stabilizing the mind and restoring the health.

As a result of researches on the influence of microorganisms living in the loess about 200-250,000 microorganisms and the effect on human beings, the presently known enzymes in the loess which are known in biochemistry are about 1,300 It is said that it reaches kind. Hwangto is a basic function to keep the human body healthy with the characteristics of far-infrared rays radiation and non-combustible materials including deodorization and purification action such as detoxification power, decomposition power, dehumidifying power and moisturizing power by the function of blocking various harmful substances generated in the residential space Contains harmful enzymes.

For example, enzymes which are harmful to human body such as protease, Diphenol Oxidase, Saccharase, and catalase are contained, It plays a role of separating into amino acids, and unnecessary rocks such as immune system and other corrupt cells can be broken down and destroyed instantaneously with the help of protease. The diphenol oxidase serves to catalyze an oxidation reaction using oxygen on the molecule and is necessary for obtaining energy necessary for the synthesis of life or bio-constituent components, thereby inducing oxidation / reduction of various organic / inorganic compounds in vivo .

In addition, the saccharose is an enzyme that hydrolyzes an enzyme called sucrose to produce crocoose (glucose) and fructose. The catalase is the most important enzyme in soil enzymes. It plays a role to remove hydrogen peroxide which is a toxin. The toxin generated in the metabolic process in the human body causes aging phenomenon. Due to strong absorption power of soil, Or diluted aging.

Since these enzymes are contained, yellow loess which shows beneficial effect on the human body is widely used for the construction purpose in order to continuously obtain the beneficial effect in the whole life of modern people.

In the present invention, in producing a brick used for building a building including a residence, a microorganism (EM) or the like is added to the yellow loess having the above-mentioned effect, thereby diversifying and maximizing the efficacy of the loess brick The method for producing the loess bricks for the implementation of the method comprises a screening step S1 for removing the impurities by screening the loess with a mesh net of intervals of 0.5 to 2 mm; An EM dilution step S2 for diluting the useful microorganism (EM) with purified water 480 to 530 times to regulate the number of microorganisms; The selected loess is mixed with purified water diluted with the beneficial microorganism (EM), and kneaded for 1 to 3 hours through a kneader at a temperature of 15 to 25 캜 and a humidity of 65 to 75% to form an ocher dough (S3); 10 to 25 parts by weight of rice hull powder selected by a mesh net at intervals of 1 to 5 mm on the basis of 100 parts by weight of the loess dough, 10 to 20 parts by weight of a sericite powder selected by a mesh net at intervals of 1 to 3 mm, 5 to 15 parts by weight of fly ash selected by a mesh network at intervals of 3 mm are mixed and then mixed in a mixer at a temperature of 15 to 25 DEG C and a humidity of 65 to 75% for 2 to 5 hours to form a mixed dough (S4); Molding the mixture dough in a press of 180 to 200 ton to form a loess brick (S5); (S6) drying the molded loess brick by day light drying for 72 to 96 hours.

In detail, the selection step S1 is configured to select pure uncontaminated loess. Since loess is a rich sediment, it is necessary to remove the impurities contained in the loess, that is, other kinds of sediments, in order to collect the loess. For this purpose, impurities consisting of particles corresponding to the size of the mesh are removed by a mesh network with intervals of 0.5 to 2 mm, and the impurities are removed from the loess to remove impurities having fine particles 2 or 3 times.

Thus, through the selection process of two or three times, the acquisition of pure uncontaminated yellow clay is ensured and the impurities are removed, thereby preventing the deterioration of compressive strength and the formation of cracks due to impurities in the kneading.

The EM dilution step S2 is a step of diluting the useful microorganisms made of EM (Effective microorganisms), that is, photosynthetic bacteria, lactic acid bacteria, yeast bacteria and antibacterial bacteria, into purified water, diluting the useful microorganisms (EM) into purified water 480 to 530 times The microorganisms contained in the beneficial microorganism (EM) form a condition for coexistence with the microorganisms of the loess. In other words, it is generally difficult to repair bricks made of bricks for use as building materials, so that the original efficacy of the bricks is expected to be continuously exhibited for a long period of time. For this purpose, a living condition, for example, . Accordingly, the present invention dilutes useful microorganisms (EMs) 480 to 530 times to induce symbiosis with microorganisms existing in the loess as the microorganisms existing in the useful microorganisms (EM) widen the space for survival.

The loess dough (S3) is a step of mixing the useful microorganisms (EM) in the selected loess through the above-mentioned selection step (S1). The useful microorganism (EM) generally has 80 kinds of microorganisms such as yeast, lactic acid bacteria, mycorrhizal bacteria, photosynthetic bacteria, actinomycetes, etc., and it is known that it has an excellent effect on the removal of odor, purification of water, prevention of oxidation of metal and food, have. These microorganisms produce antioxidant or physiologically active substances and inhibit corruption. These useful microorganisms are also microorganisms that have been used for fermentation of food for a long time by mankind. These microorganisms generate antioxidant activity or antioxidants, and co-exist with each other and suppress corruption, leading to the direction of natural revival.

In particular, useful microorganisms (EMs) are symbiotic with various species, which are not merely coexistent, but act as a living organism by combining different species such as aerobic bacteria, anaerobic bacteria, degrading bacteria and synthetic bacteria. It is also known as a beneficial microorganism group to prevent the generation of harmful substances due to the smell during the process of mineralization (gas generation) by suppressing the intense oxidizing action to exacerbate the environment, human and crop conditions through the interaction of these microorganisms have. For the mutual coexistence of the microorganisms of the useful microorganism (EM) and the microorganism existing in the loess, 30 to 40% by weight of purified water diluted with 480 to 530 times of EM and 60 to 70% by weight of loess were mixed, Preferably, the dough is constituted, and the selected yellow clay is mixed with purified water diluted with the useful microorganism (EM), and the mixture is kneaded for 1 to 3 hours through a kneader at a temperature of 15 to 25 ° C and a humidity of 65 to 75% So as to form a loess dough.

The mixing and kneading step S4 comprises mixing the rice hull powder, the sericite powder and the fly ash with the yellow clay formed by the loess dough step S3.

The rice husk powder is easy to handle because it is easy to supply and receive with the surface of rice. In addition, by forming the porosity itself, there is an advantage that the essence of the loess soil, which is the object of the present invention, can be maintained and its efficacy can be maximized. That is to say, the rice husk powder is excellent in heat insulation and has been used as a wall of a traditional house by mixing yellow clay and lime for a long time, and the frequency of its use is increasing as a natural-friendly material in the modern times. In addition, the rice husk powder contains about 230 kinds of various minerals, which makes it possible to survive microorganisms. When mixed with the loess of the rice husk powder, an air layer is formed between the cracks of the rice husk powder to improve the adiabatic effect and anti- There is an advantage that the physical properties are improved.

In addition, the sericite powder is a generic term of dense or fine vinyl-like muscovite, often called "sericite", belonging to the monoclinic system, and has a white or grayish white pearl luster. It has excellent infrared and deodorant effect And it is also used in textile industry, filler, and abrasive as well as raw materials such as paints, pigments, medicines, and cosmetics because it is easy to coat objects with fine particles and scales.

The sericite powder is one of the mica. It is a rock produced from granite granite (pegmatite). It is excellent in oxygen supply and has an intermediate property between metal and nonmetal due to its electrical properties.

And, fly ash is a type of pozzolan made of siliceous material as fine claystone. Such fly ash reduces hydration heat of the loess bricks and improves the water tightness, thereby being used as the strength promoter of the loess bricks in the present invention.

The rice husk powders having the above characteristics are prepared by screening with a mesh net having intervals of 1 to 5 mm, and the sericite powders are selectively prepared with a mesh net having intervals of 1 to 3 mm. 10 to 25 parts by weight of the rice husk powder, 10 to 20 parts by weight of the sericite powder and 5 to 15 parts by weight of fly ash were mixed with 100 parts by weight of the loess dough, Put in a blender under temperature and humidity conditions of 65-75% and knead for 2-5 hours to form a mixed dough.

As a result of controlling the moisture content of the mixed dough to 10 to 25% by the mixing dough step S4, the amount of the far-infrared rays emitted and the anion effect are increased as the rice hull powder, the sericite powder and the fly ash are mixed in the loess, The enzyme contained in the enzyme and the loess enzymes react with each other to improve the deodorization rate and purification ability. In addition, especially in the curing process of the yellow loess and the rice husk powder, a large number of yeast groups are converted into inorganic compounds through an aging process. As time passes, the yeast groups are more advantageous as they are proportional to the time. In addition, it is necessary to have a certain viscosity for making bricks. By adding the rice husk powder to the diluted yellow loam dough, the water content is adjusted to 10 to 25%, and cracks due to shrinkage after drying can be prevented positively.

In the mixing dough step (S4), yellow ocher is diluted in purified water diluted with useful microorganisms (EM) before mixing the rice hull powder, the sericite powder and the fly ash in the yellow loam, The mortar was sprayed several times on each of the rice husk powder selected by the mesh network of the interval, the sericite powder selected by the mesh network of the interval of 1 to 3 mm, and the fly ash selected by the mesh network of the interval of 1 to 3 mm, (S4-1) for making the loess water evenly coated on the powder, the sericite powder and the fly ash.

This is to sufficiently wet dough water in the rice husk powder, the sericite powder and the fly ash prepared for the mixed dough in advance so as to smoothly perform the dough in the mixing dough stage (S4), and the rice husk powder, Powder and fly ash, respectively.

As another method for achieving the above-mentioned effect, in the mixing dough step (S4), before mixing the rice hull powder, the sericite powder and the fly ash in the yellow dough, the yellow water is added to the purified water diluted with the useful microorganism (EM) The mixture was subjected to dilution to make loess water. Then, the rice husk powder selected by the mesh net at intervals of 1 to 5 mm was added to the loess water, the sericite powders selected by the mesh net at intervals of 1 to 3 mm, (6-12 hours), and then removing the loess water to prepare a mixture preparation step (S4-2) in which the loess water is evenly coated on the rice husk powder, the sericite powder and the fly ash.

Meanwhile, the method may further include naturally drying each of the rice husk powder, the sericite powder and the fly ash prepared in the two preparation steps (S4-1, S4-2) for 12 to 24 hours. This is to double the efficacy of the main component, loess, by protecting the surface of the coarse-grained horseshoe powder, sericite powder and fly ash.

The step of forming the loess bricks (S5), which is performed after the mixing and kneading step (S4), is a step for compressing and molding the loess dough into presses of 180 to 200 tons. The yellow loam obtained through the above-described steps is placed in a 300 mm x 150 mm x 130 mm mold, and a predetermined shape is formed by a 180 to 200 ton press. At this time, when the pressure is less than 180 tons, the pressure is somewhat insufficient to cause cracking. When the pressure is more than 200 ton when the press is over 200 tons, the shrinkage occurs after drying and it is not suitable for the size disclosed in the present invention. A larger amount of bricks are used, which may cause a problem that the construction cost is excessively increased.

In addition, in the step of forming the loess bricks (S5), the sericite powders selected by the mesh net having the intervals of 1 to 3 mm are uniformly prepared on any one of the upper and lower sides of the press, It is possible to constitute such that the sericite powder is exposed on the entire outer surface of one side of the two side surfaces.

The sericite powder belongs to a monoclinic system and can be exposed to the surface of a yellowish-white brick having a pearly luster of white or off-white color, thereby having a decorative effect due to the luster effect or a function according to the luster.

Further, after the step of forming the loess bricks (S5), the process of spraying the loess water made by diluting the loess in the purified water diluted with the useful microorganism (EM) onto the surface of the loess brick or immersing the loess brick in the loess water The effect of the loess bricks can be doubled.

Meanwhile, the drying step (S6) performed after the step of forming the loess bricks (S5) is a step of drying the compressed loess bricks, and is dried in the daylight for 72 to 96 hours. The time set by the present invention is to prevent the deleterious effects from disappearing due to the fact that the rice husk powder, the sericite powder and the fly ash are arbitrarily set in the loess, that is, the conditions that the microorganisms present in each of them are naturally viable, It is possible to keep the fermentation temperature of the loess naturally as well as to make it an eco-friendly brick, so that it does not require any additional equipment.

In addition, it naturally dries to stabilize the microorganisms present in the compressed yellow clay brick. This can greatly increase the antioxidants produced during microbial metabolism.

Hereinafter, embodiments of the present invention will be described in further detail to demonstrate the effectiveness of the present invention.

As a result, it was found that E. coli increased BLANK by about 677% after 24 hours of bacterial infection, but did not proliferate in Example 3 and showed a reduction rate of more than 10% Pseudomonas aeruginosa increased BLACK by about 674% after 24 hours, but did not proliferate and decreased by more than 10%. As a result, it was confirmed that yellow clay dough mixed with 60 ~ 70 wt% of loess and 30 ~ 40 wt% of water diluted 500 times with beneficial microorganism (EM) had an effect on the antibacterial activity of yellow loess and useful microorganism (EM) .

As shown in Table 4, the emissivity of the control group 1 was 84.6% and the radiant energy thereof was 3.19 × 10 2 W / m 2. The emissivity of the control group 2 was 83.7% and the radiant energy was 3.16 × 10 2 W / ), And the emissivity of Example 4 was 91.4% and the radiant energy was 3.69 × 10². As a result, it was confirmed that the effect of radiant energy and emission of far-infrared rays was maximized in the yellow clay bricks produced in Example 4.

As shown in Table 5 above, BLANK and Example 5 are the results measured at a measurement distance of 1 cm. In detail, BLANK generated 75 anions / cm3, and Example 5 produced 86 anions / cm3. As a result, it was confirmed that the deodorization ratio was improved by mixing with the husk powder, the sericite powder and the fly ash in the loess, and the purification ability of the surrounding space was improved.

As shown in Table 6, the results of the strength (kgf / cm2) of Example 6 are as follows. First, according to KSL 4201, the strength of the loess bricks is at most 10% The strength (㎏f / ㎠) is specified to be suitable for use when it is 210 or more. As a result, it was found that the strength of the control group 1 including 5 parts by weight of the sericite powder and 3 parts by weight of the fly ash was less than the standard value of 197 kgf / cm 2 based on 100 parts by weight of the loess dough and 10 parts by weight of the sericite powder and 5 parts by weight of fly ash It was found that the control group 2 was found to be effective at a standard of 224 kgf / ㎠ in the control group 3 containing 20 parts by weight of the sericite powder and 15 parts by weight of the fly ash. 25 weight parts of the powder, and 20 weight parts of the fly ash were 225 kgf / cm 2 in the control group 4, but it was confirmed that there was no difference in the strength in the control group 3.

The yellow clay bricks produced by the method of manufacturing EM clay bricks according to the present invention can be used for the production of useful microorganisms (EMs), yellow clay, rice hull powder, By combining the sericite powder and the fly ash in an optimum mixing ratio, the environment for the survival of the microorganisms existing in each of them can be established, and the coexistence of one community can maximize the beneficial effects to the human body, have.
