Anion-Emitting Solid Body Containging Salt and Producting Method Thereof}

The present invention relates to a salt solid and a method for preparing the same, and more particularly, to an salt solid produced by adding an additive to salt to generate anions and baking and cooling the same under specific conditions.

Salt is essential for maintaining the health of the human body, is used for food and beauty, and may also be used as a building interior material. In particular, salt has an antibacterial and deodorizing effect to remove harmful bacteria and unpleasant odors that are invisible, and has excellent dust collecting function to remove fine dust in the air. In addition, it is used to treat allergic diseases, respiratory system, vascular system diseases or rheumatism. Recently, moldings such as interior materials of a sauna using salt, bricks for interior decoration, lamps, and the like have also been used.

On the other hand, tobacco smoke, sulfur dioxide, nitrogen oxides, carbon monoxide, ozone, and various organic substances present in the air form cations. Anions can purify and settle these cations to remove and keep the air clean and fresh. have.

In addition, X-rays, R-rays, ionizing radiation, and ultraviolet rays emitted from various electronic and electrical products, such as TVs, PCs, and mobile phones, which are frequently encountered in living spaces, have high energy. Increased cations can cause diseases such as asthma, bronchitis, headache, blindness, low back pain, stiff shoulders, nervousness, tension, menstrual irregularities, lethargy, depression, dermatitis and birth defects.

On the contrary, the anion cleanses the blood by increasing the ionization rate of minerals such as calcium, sodium, and potassium in the blood and alkalizing it. In addition, by generating an endorphin and enkapyrin to increase the ionization rate of calcium and sodium in the blood vessels to help to recover from fatigue and recovery of physical strength, it is effective to relieve pain by activating the healthy cells of the severe pain. In addition, the anion increases the amount of globulin, an immune component contained in the serum, thereby increasing resistance to infection.

Recently, sculptures may be manufactured with salt, but failure to control humidity in the manufacturing process may cause a problem such as breakage of the shape of the sculpture or breakage of the generated sculpture.

In addition, the anion generated in natural salt is usually about 100 / cc is very small, there is a problem that the effect of the above anion can not be seen through the molding made of ordinary salt.

In addition, an object of the present invention is to prepare a salt solid that can generate a large amount of negative ions beneficial to the human body.

In order to solve the above problems, in the present invention, as a salt solid containing salt, anion generating material, and magnesium phosphate, 1 to 3 weight of anion generating material is added to 100 weight of salt which is first calcined at 600 to 800 ° C for 6 to 8 hours. , Magnesium phosphate 0.031 ~ 0.052 weight is added, under 1.5 ~ 3 atm, pressurized and molded at 400 ~ 600ton / ㎠, and after the secondary firing at 600 ~ 800 ℃ for 2 to 4 hours, characterized in that the produced by cooling It provides a salt solid that releases anions.

In this case, the anion generating material may include all or part of SiO ₂ , Al ₂ O ₃ , TiO ₂ , MgO components.

In addition, SiO ₂ : Al ₂ O ₃ constituting the anion generating material. : TiO _2: is preferably 5 to 10: the ratio of the MgO 30 ~ 50: 35 ~ 55 : 5 ~ 10.

In addition, all or part of the primary calcined salt is pulverized, salt that releases the anion, characterized in that the non-crushed salt of the original size and the crushed salt is formulated in a weight ratio of 20 ~ 40: 60 ~ 80 Provide the shape.

At this time, the pulverized salt, it is preferable to mix the salt pulverized into 160 neck, 200 neck, respectively, so that the weight ratio of 160 neck: 200 neck is 3-5.

In addition, in the present invention, the first step of baking the salt at 600 ~ 800 ℃ for 6 to 8 hours to produce a calcined salt (S1); Making anion generating salt by adding 1 to 3 weight of anion generating material per 100 weight of the calcined salt (S3); Adding 0.03 to 0.05 weight of magnesium phosphate per 100 weights of the anion generating salt and stirring to make mixed salt (S4); Pressing and molding the mixed salt at 400 to 600 ton / cm 2 under 1.5 to 3 atmospheres to form a salt solid (S5); Secondly baking the salt solid at 600 to 800 ° C. for 2 to 4 hours (S6); After the secondary firing, it provides a method for producing a salt solid to release the anion, characterized in that it comprises the step (S7) of cooling the salt solid.

At this time, after the calcined salt is made through the primary firing, all or part of the calcined salt is pulverized, and the salt of the original size that is not crushed and the crushed salt are blended in a weight ratio of 20 to 40: 60 to 80. It may further comprise the step of making salt (S2).

In addition, the first calcined salt may further comprise the step of pulverizing with 160 wood and 200 wood, 160 wood: 200 wood and the weight ratio of 3 to 5: 1 to mix with the calcined salt of the original size does not grind. have.

In addition, before adding the magnesium phosphate to the anion generating salt, the anion generating salt may be stirred in a stirrer which is preheated for 5 to 10 minutes.

In addition, in the cooling of the salt solids, the heating furnace can be kept in a closed state for 10 to 14 hours while the salt solids are placed in the heating furnace.

In the present invention, it is possible to enhance the strength of the salt solid through the baking, stirring and cooling of the salt.

In addition, in the present invention, it is possible to maintain the shape of the salt solid by adding magnesium phosphate to properly maintain the humidity in the process of calcining the salt.

In addition, the present invention has the advantage of generating an appropriate amount of anion beneficial to the human body by including an additive that releases anion.

Hereinafter, a preferred embodiment according to the present invention will be described in detail. As shown in FIG. 1, the salt solid of the present invention may be prepared by firstly calcining and grinding salt, adding anion generating material, stirring and molding, and then calcining and cooling secondarily.

First, the salt is put in the kiln and the primary firing is carried out for 6-8 hours at 600 ~ 800 ℃ (S1). At this time, when the firing temperature is lower than 600 ℃, the density of salt is not sufficiently increased due to heating, and if the firing temperature exceeds 800 ℃, the melting point of the salt, the salt is dissolved, it is difficult to manufacture a dry salt solid. Therefore, it is preferable to maintain a temperature of about 650 ~ 750 ℃ that is enough to remove impurities in the salt through the primary firing. On the other hand, the salt used in the production of the salt solid according to the present invention is not limited in kind, it is preferable to use a natural salt of high quality salt in consideration of the density between salt crystals and the strength after production. In addition, rock powders, such as ganban rock and wood quarry, which have a far infrared ray emitting effect, may be added to the kiln used in the firing.

After the first firing, the fired salt may be pulverized and blended by adjusting the particle size (S2). At this time, the calcined salt can be pulverized to various sizes up to 80 ~ 200 neck, the salt ratio of the crushed salt and the original size of the non-pulverized salt can be made with 20 ~ 40: 60 ~ 80 . In addition, the crushed salt may use a single size of salt, but it is also possible to mix salts of various sizes according to the shape and strength of the salt solid. For example, in order to manufacture a salt panel used as a building interior material, it is preferable to mix the crushed salt so that the ratio of 160 tree: 200 tree = 3 ~ 5: 1 ratio.

The salt is crushed and blended to add a material capable of generating anions (S3), the anion generating material may include minerals such as SiO ₂ , Al ₂ O ₃ , TiO ₂ , MgO. In general, the amount of negative ions beneficial to the human body is about 800 to 1000 per 1cc in the air. If there are less than 800 negative ions per 1cc, the beneficial effects due to negative ions are not properly exerted, and more than 1000 are harmful to health. When the anion generating material is added at a ratio of 1 to 3 weights per 100 weights of the salt, it is possible to release an amount of negative ions beneficial to the human body. In particular, it is preferable to add 2 weight of anion generating material per 100 weight of the salt, in which case, the material generating the anion may include only a single kind of mineral, but may also include various kinds of minerals. In this case, the minerals may be included such that the weight ratio of SiO ₂ : Al ₂ O ₃ : TiO ₂ : MgO is 30 to 50:35 to 55: 5 to 10: 5 to 10, and the content of Al ₂ O ₃ is SiO _2. Equals or SiO ₂ To greater than _{SiO 2: Al 2 O 3:} = 40: preferably from 40 to 45 degrees.

After the anion generating material is added to the compounded salt, the stirring operation may be performed so that the compounded salt and the anion generating material are mixed well (S4). The stirring operation may be performed at one time, but may be divided into 1 and 2 times. When the process is divided into 1 and 2, the first agitation is performed for 5 to 10 minutes in the stirrer so that the mixed salt and the anion generating material are well mixed, and by heating the stirrer in advance to remove the natural moisture of the salt in the stirring process, Salt can be dried. As such, by drying the salt, it is possible to prevent the work efficiency degradation due to moisture in the subsequent manufacturing process.

After the first stirring, magnesium phosphate is added, and the mixed salt and the magnesium phosphate may be mixed to make a mixed salt by performing second stirring. The magnesium phosphate acts as a coagulant so that the salt tissues are tightly bonded to each other. Since the magnesium phosphate is deliquescent, when the addition amount is too large, the amount of water absorption increases, making it difficult to form a salt solid, and the work may be disturbed due to moisture. In addition, if the addition amount is small, since the binding force between the salt tissue is not sufficiently strong, the shape of the salt solid is not maintained and the strength is inhibited. Therefore, the magnesium phosphate is preferably added at a ratio of 150 to 250 weight per 500000 weight of the anion generating salt mixed with the mixed salt and the anion generating material.

In this way, the salt is first calcined, and a part or all of the salt is pulverized and blended to form a compound salt, and then an anion generating substance and magnesium phosphate are mixed to form a salt solid. Salt solids of the present invention can be produced in a variety of sizes, in order to be used as interior materials, such as buildings, in consideration of the degree of bonding between salt tissue, it is preferable that the thickness is about 10 ~ 30mm, width 300x300mm2. The molding may be performed by compressing the mixed salt at 400 to 600 ton / cm 2 under 1.5 to 3 atm. In this process, the density of salt tissues is increased, thereby increasing the strength of the salt solids, and forming the salt solids. At this time, the higher the pressure of the molding machine, the higher the strength of the salt solid body, the pressing force of the molding machine has a limit, as will be described later, it is possible to enhance the strength through the secondary firing.

After forming the mixed salt to form a solid, secondary baking may be performed. It is preferable that the secondary firing proceeds to 600 to 800 ° C. similarly to the primary firing, and the firing time may be 2 to 4 hours. In secondary firing, the bending strength can be increased by stabilizing the salt structure through thermal expansion and thermal contraction. As described above, the secondary firing can be performed without applying too much pressure in the molding process in order to express a predetermined strength. Strength can be increased through.

After the second firing, the salt solids may be naturally cooled in a state of low cooling for about 12 hours. At this time, the salt solids are aged while maintaining the sealed state. If the sealed state is not maintained, the shape of the salt solid may be broken or broken due to rapid cooling, and defects may occur.

(Example 1)

The sun salt is first calcined at 600 to 800 ° C. for 6 to 8 hours, and then pulverized and blended in 160 necks: 200 necks: salt before crushing = 70: 15: 15 by weight. SiO ₂ : Al ₂ O ₃ : TiO ₂ Anion-generating salts are mixed by mixing the anion-generating materials at a weight ratio of 40: 45: 7.5: 7.5 at a ratio of 2 wt. Drying is carried out by stirring the anion generating salt for about 10 minutes in a stirrer which has been heated beforehand, and during the second stirring, magnesium phosphate is added to the mixed salt 500kg in a 200g weight ratio and stirred. After the first and second stirring, the molding operation is performed at a pressure of 500 ton / cm 2 under 2 atm, and secondary baking is performed at 600 to 800 ° C. for 2 to 4 hours. After the secondary firing, the solid state is aged by natural cooling for about 12 hours while the heating furnace is sealed. According to the bending strength test method (KSL1001-2003) of porcelain tiles, the salt solid produced in this way may have a bending strength of 53 N / cm after the secondary firing, and may be used as a building material.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
