It relates to a manufacturing method.

Generally, ceramics refers to materials or products obtained by molding and drying clay or clay-like material in a plastic state to give the required strength and finally firing at a sufficient high temperature. These ceramics can be classified according to their use, to make edibles or tiles used to assemble or decorate buildings, refractory materials used to make metals, insulation materials such as porcelain or steatite used in the electrical industry, and chemical products. It can be divided into stoneware and porcelain used in sanitary facilities, stoneware used to drain water and sewage, porcelain used as kitchen utensils and tableware, and electronic materials used in radio and television accessories.

As a raw material of ceramics for manufacturing such ceramics, various components existing in nature are used. For example, montmorillonites (Al ₂ O ₃ · 4SiO) in which clay, plastic clay, volcanic ash or tuff have been modified as clay raw materials containing not only various clay minerals but also accompanying minerals and organic matters, such as feldspar, mica and siliceous clay Soft clay composed mainly of ₂ · 2H ₂ O) -based minerals is used.

Recently, in response to the desire of consumers to possess and use ceramics having various functions due to the improvement of the standard of living, researches on developing functional ceramics have been actively carried out by mixing components with special functions with existing ceramic components. It's going on. For example, ceramics having increased strength, ceramics releasing useful components for the human body, and antimicrobial ceramics have been variously developed due to the rapid development of the material engineering field. As a raw material for manufacturing such functional ceramics, various components as mentioned above are used, and in recent years, researches employing germanium (Ge) and zeolite (materials having a large amount of far-infrared emission) as raw materials of ceramics have.

As mentioned above, according to the present invention, instead of the expensive raw materials used in the manufacture of ceramics, new functional products can be produced using low-cost 4A-type synthetic zeolites, and inexpensive ceramic products can be obtained in terms of price. have.

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

Generally, zeolites have a tetrahedral structure of SiO ₄ , AlO ₄ in which four oxygen atoms are arranged around a silicon atom or an aluminum atom. The tetrahedral structures of SiO ₄ and AlO ₄ are attached to various geometric shapes to form secondary building units (SBUs), which are combined to form various polyhedrons. Finally, they again combine three-dimensionally to form zeolite crystals.

These zeolites vary in pore size depending on the type of cation ion exchanged in each crystal. However, the size of the pores is important because it influences the water content and the adsorption capacity. Table 1 shows the various types of synthetic zeolite components and pore sizes.

In the present invention, 4A-type zeolite is employed as a raw material for producing ceramics, and in addition, a small amount of British clay, Goryeo quartzite, Buyeo feldspar, Kasido pottery stone, alumina and talc are used. At this time, the components of the zeolite are first changed at a constant ratio, and thus other components are changed at an appropriate ratio. To this end, the composition of each component is determined using a known Seger formula.

Table 2 above is divided into oxides, natural minerals as basic, neutral and acidic oxides. However, although RO has alkali R ₂ O (Li ₂ O, Na ₂ O, K ₂ O), it is included in RO group for convenience. Referring to Table 2, the ceramic display method and seger (Seger) display method of the base is as follows.

로 한다.

Shall be.

At this time, the composition ratio of Seger determines the composition for each component so that the ratio of crystalline and glassy SiO ₂ / KNaO = 6 to 10 (mass fraction) when Al ₂ O ₃ = 1.

For example, the zeolite component content is 20.0 wt%, clay is 26.5 wt%, feldspar is 8.0 wt%, silica is 15.0 wt%, pottery is 26.5 wt%, alumina is 3.0 wt%, bow When the pomegranate was determined to be 1.0% by weight, the content of SiO ₂ /KNaO=3.824/.581=6.576 at this time was satisfied.

Table 3 shows the component content of 4A-type zeolite.

Referring to Table 3, it can be seen that the component content of Na ₂ O representing the glassy component is 18% by weight. This is a considerable amount compared to other ceramic raw material ingredients. On the other hand, feldspars, which vitrify and hold crystals during firing of ceramic moldings, account for 6.67% by weight, which is about one third of the amount of zeolite. Therefore, when 20% by weight or more of zeolite is added, the ratio of glass is increased. The plastic strength falls below 900. In addition, the boiling phenomenon of the zeolite occurs due to the effect of undersintering to create a large pores therein to weaken the strength. Therefore, content of zeolite is kept at less than 20 weight%. Preferably, it is maintained within the range of about 5 to 20% by weight.

On the other hand, if the component content of the clay is 28% by weight or more, the plastic shrinkage is 13% or more, causing overshrinkage of the substrate, it is difficult to apply to the existing production process. It is also difficult to meet new process and product specifications. Therefore, the content of clay is preferably kept below 28% by weight. However, when the content of clay is 25% by weight or less, the moldability decreases, so that the molded product (primary dry product) is cracked and the molded product is broken, and thus the productivity and quality of the product are reduced due to the weakening of the green strength. . Therefore, the content of clay is preferably maintained in the range of about 25 to 28% by weight.

On the other hand, since the main component of the silica is SiO ₂ , when the silica is finely divided, the wear of the machine increases and power costs are high. Therefore, the component content of the silica is preferably maintained in the range of about 10 to 30% by weight.

Feldspar melts at low temperatures and serves to connect other components. Therefore, a certain component should be included, but when included in a large amount, the glass tends to be vitrified and the surface of the fired article becomes smooth. As a result, the component content should be adjusted according to other components. Since zeolite also contains a large amount of Na ₂ O as a glass component, the component content of feldspar is preferably maintained in the range of about 5 to 20% by weight, preferably 7 to 13% by weight.

Porcelain is a raw material that can make porcelain by firing itself, and has a high quartz content, thereby improving strength after plasticity. However, when 40% by weight or more of the pottery is contained, the molding becomes difficult, so it is preferable to keep it within the range of about 10 to 40% by weight.

Alumina is a material containing Al ₂ O ₃ as a main component, and as the content of the component increases, the firing temperature may be increased and production costs may increase. Therefore, the content of alumina is preferably maintained in the range of about 0 to 10% by weight.

Finally, talc is a substance added mainly for whiteness enhancement, and has a small coefficient of thermal expansion and a high resistance to thermal shock. However, when the content of talc is high, the color becomes yellowish or blue, and it is preferable to keep it within the range of about 0 to 5% by weight.

After the porcelain raw material having the composition as described above is selected, porcelain is produced according to the porcelain manufacturing process of the present invention as shown in FIG. In other words, after the selection of the porcelain raw material, the raw material is crushed to refine the particles of the raw material and at the same time have a grain size suitable for the request. To this end, first, a mass or coarsely pulverized raw material is obtained by using a jaw crusher, a fret mill, an edge runner, a hammer mill, or a roll grinder. do. Next, the finely ground or coarsely pulverized raw material is pulverized using a ball mill or the like. In the grinding of ceramic raw materials, an appropriate amount of water is used as an auxiliary material. By the way, when the desired particle size adjustment is not achieved only by grinding, water is used to classify the particles and mix them or classify the ceramic raw materials separately and then mix them.

After pulverizing the porcelain raw material, the finely ground granulated particles are separated from the wet pulverized raw material or the combination using a sieve. At this time, the sieve is used to pass through the thin eye after passing through the big eye, and the fine eye may be 120 to 150 mesh. After passing through a sieve, the iron incorporated into the sheet during the milling process is removed from the sheet using an electromagnet. Thereafter, harmful water-soluble salts such as calcium and magnesium sulfates are removed from this chapter. Agitation of the harmful salts is sufficiently stirred and dispersed.

Next, mix the two sheets together to make a clay. Thereafter, a filter press is used to remove water from the protected clay or clay field. Alternatively, a dehydration method using a vacuum or applying centrifugal force may also be used.

By the way, in the case of dehydrated clay or clay sheets dehydrated by a filter press to make a cake, or a clay in a state where water is mixed with dry raw materials, complete uniformity is insufficient and air is enclosed. Therefore, it is necessary to mix or knead according to the contents of the product. To this end, kneading is performed using a pug mill, a de-airing pug mill, or a kneading table. In other words, the raw materials are mixed so that the composition is constant and the water content is constant no matter which part of the raw materials is taken.

Thereafter, the porcelain base is used to be molded as uniformly as possible in the molding gypsum mold or mold used as an auxiliary material, and then processed into a desired shape, the base having any complex shape, especially a surface. In the case of solid injection molding, solid injection molding is used, and when the base is dented, dry pressure molding is used. Thereafter, the base is molded and moisture is evaporated away from the base molded by natural drying or a dryer.

In contrast, the pressure injection molding method injects a slurry obtained by dispersing porcelain particles such as clay into a solvent such as water into a porous mold, pressurizes the slurry to absorb the solvent into the mold, solidifies the slurry, and then demoulds the solidified molded product. That's the way it is. In this pressure injection molding method, a solid casting in which a mold absorbs a solvent on both sides of the molded article, and a surplus slurry is discharged after the mold absorbs a solvent on one side of the molded article and an article having a predetermined wall thickness is obtained. There is a drain casting. Exhaust injection molding can produce ceramic articles having complex configurations using relatively simple equipment.

In the case of molding by using the solid injection molding method or the discharge injection molding method, the injection sheet which has been filtered is injected into a mold made of gypsum. At this time, since the water used in the molding process is unnecessary to have strength so that the mold does not collapse during handling or in the kiln, the water is first evaporated and removed from the molded body by using natural drying or a dryer. Next, the undried portion of the first dried injection rod is removed from the mold and then dried secondly. Thereafter, the secondary dried infusion rolls are demolded from the mold.

Next, the demolded double sheets are dried in a tertiary manner, and then fired in a kiln at a sufficient temperature, preferably at a temperature of about 1,000 to 1,300 ° C.

The porcelain body discharged from the kiln after the firing is composed of fine powder and thus exhibits roughness in the same size unit as the diameter of the particle. In other words, when the molded body is fired, the base is shrunk, so that the dents on the surface are reduced to the size of the shrinkage ratio, but the minute remains. The surface of the substrate is coated with glass to make the surface roughness small and smooth, and to prevent it from becoming dirty or sticking during use, or for aesthetics. Particularly, when the plastic body is porous, it is very important to prevent the penetration of liquids or gases, so that the glaze is applied to form a protective glassy coating on the surface of the body. This makes the surface of the base smooth, which increases gloss and enables various decorations.

In order to test the physical properties of the ceramics manufactured as described above, after the specimen was prepared, the drying / plastic shrinkage, molding / plastic strength, porosity / absorption rate, whiteness, thermal expansion coefficient was measured, based on the results of each component Was analyzed.

[Dry shrinkage]

First, the dry shrinkage of porcelain specimens prepared according to the present invention was measured. The dry shrinkage was measured by measuring the length after complete drying after drawing gold to a length of 90 mm in the prepared specimens to determine the shrinkage. 1 is a graph showing the results of measuring dry shrinkage of ceramics manufactured according to a preferred embodiment of the present invention. The values included for some flexural specimens showed a shrinkage greater than 1%. These values are mainly shown in the mass fraction (when SiO ₂ / KNaO, Al ₂ O ₃ = 1) mainly in the value of 5.5 to 6.2 and has a constant value at 0.8 shrinkage from 6.6 to 7.2 value. In addition, it can be seen that more than 7.1 starts to increase gradually.

This phenomenon can be considered by the effect of the evaporation of the surface moisture, in theory, if the surface moisture evaporates faster than the internal diffusion of the moisture, the shrinkage is increased. In other words, an increase in the mass fraction of SiO _{2 means that} the dry shrinkage decreases or stabilizes around 1%, i.e., 1.0 ± 0.1 to 0.2. In the middle right of the graph, the mass fraction gradually increases from 7.3. In addition, since the shrinkage ratio is 1.28% at the mass fraction 12, it can be seen that when the mass fraction is increased to 7.3 or more, the shrinkage increases linearly. Therefore, it can be seen that the mass fraction should be 6.2 or more in order to prevent the shrinkage occurs so that the body cracks.

[Plastic shrinkage rate]

The plastic shrinkage was measured by measuring the length of the fully dried porcelain specimen by firing gold with a length of 90 mm and determining the shrinkage rate. The plastic shrinkage was mainly measured in the range of 10-12%, but it was found that the shrinkage increased from 14% to 14% by mass fraction, which is due to the fact that the clay contained more than a certain component (about 28%). It can be interpreted as a result of shrinkage, shrinkage due to the release of bound water with zeolite, and the warpage of the specimen. First, the mass fraction showed a shrinkage of 13% at 6.2 and 14% at 6.5, but was still measured in the range of 10 to 12% in the vicinity. Table 4 below shows the approximate values.

As can be seen from Table 4, when the zeolite is contained, it is confirmed that the shrinkage is increased by about 0.5 to 1.0% due to the shrinkage caused by the structure being densified by the release of the combined water bonded to the pores of the zeolite. When the content of clay is reduced to less than 28%, shrinkage can be reduced to less than 12%. That is, when the component content of clay is 25%, the plastic shrinkage rate is 11.8% (zeolite 20%) and 9.91% (zeolite 10%).

On the other hand, specimens containing 31% clay (16.5% zeolite) exhibited a shrinkage of more than 13%. The main plastic shrinkage increased as the content of clay was increased rather than the content of zeolite. If the content of clay is more than 30%, it shows a high shrinkage of more than 12%.

[Molding strength measurement]

After drying the porcelain specimens made for measuring the molding strength by natural drying for 1 hour at a temperature of 110 ℃ in a constant temperature dryer, then drying for 2 hours in a desiccator and measuring the molding strength in a bending strength meter It was. The formula representing the bending strength is as follows.

Indicates. Table 5 shows the results of the molding strength according to the content of the zeolite.

As can be seen from Table 4, the molding strength increases as the content of zeolite increases to 10-20 wt.%. This is because the moisture contained in the molding is rapidly released when the ceramic specimens are dried at a temperature of 110 ° C. in a constant temperature dryer for 1 hour due to the adsorption of zeolite. At this time, the porcelain specimen exhibits greater molding strength than the substrate having irregular pores.

[Firing Strength Measurement]

The completely dried specimens were calcined in a kiln and measured on a bending strength meter. Figure 2 (a) is a graph of the resulting plastic strength according to the mass fraction of porcelain prepared according to a preferred embodiment of the present invention. As shown in FIG. 2 (a), the plastic strength was somewhat increased as the SiO ₂ / KNaO ratio (based on Al ₂ O ₃ = 1) and then decreased. That is, the bending strength value was exhibited in the measured value is more than 1,000Kgf / ㎠ between the SiO ₂ / KNaO ratio of 6.7 to 7.3 of the value of the ratio of SiO ₂ / KNaO exhibited a tendency to begin to decrease from 7.1.

Figure 2 (b) is a graph showing the overall modification of the resulting plastic strength according to the mass fraction of porcelain prepared according to a preferred embodiment of the present invention. This is based on the average value of each specimen, and the slope of the graph is rapidly increasing at a ratio of approximately 6.5. This result means that if the ratio of vitrification of the KNaO component is relatively increased, the ratio of amorphous material after firing becomes relatively large and the strength decreases. In other words, when the mass fraction is low and the KNaO component is large, the firing temperature is lowered, and as a result, the temperature is fixed and progressed, so that the tendency of underfiring becomes large, thereby intensifying the strength. From these results, it was expected that the mass fraction should have a value of about 7.0 or more in the temperature range of 1,170 to 1,200 ° C.

[Porosity / absorption rate measurement]

The porosity is a value indicating how much voids exist in the substrate, and the approximate firing temperature can be known by measuring the porosity and the water absorption. To this end, the specimens were heated from room temperature to 1,200 ° C in a ramp where the temperature increased linearly and gave a soaking time for 1 hour and 30 minutes. And after 4 hours and 30 minutes, it was made to have a constant temperature distribution to 940-1,200 degreeC at least. Porosity was measured using Archimedes' principle. Figure 3 (a) is a graph showing the porosity / absorption rate measurement results according to the temperature of the porcelain produced according to a preferred embodiment of the present invention, the experimental temperature and the firing temperature is the same. Figure 3 (b) is a graph showing the results of measuring the porosity / absorption rate according to the temperature of the porcelain prepared according to the preferred embodiment of the present invention, the case is made of a low degree of burning of the base. In FIG. 3 (a) and FIG. 3 (b), the temperature of the portion where the porosity and the water absorption fall to almost " 0 "% is the firing temperature.

[Whiteness Measurement]

After drying the mixture of the dried specimens for about 1 hour at a temperature of 110 ℃ in a constant temperature dryer, measure about 15g on a balance, add 7 to 8 drops of the binder and mix well. Next, put them in a circular frame and dip them into discs. The finished specimen was calcined and polished and measured using a whiteness measuring device (ReFelectometer Model Tc-6D, Tokyo Denshoku co., LTD). Zero adjustment was performed using a standard piece.

4 is a graph showing the result of measuring whiteness according to the mass fraction. Referring to FIG. 4, the degree of whiteness is high in the portion having a low mass fraction within the range of 74 to 90%, and gradually decreases and then becomes constant as the mass fraction increases. Whiteness is an indicator of the performance of porcelain products. To improve the quality, high whiteness should be shown. In general, in the case of ceramics using zeolite showed a high whiteness of more than 75% showed good results.

The whiteness increases when the degassing process is carried out when making the body. In addition, as the content of zeolite increases, the mass fraction is lowered and thus high whiteness is shown. 20% zeolite-containing specimens show about 5-6% improvement in whiteness compared to 10% -containing specimens. Thus, the whiteness can be obtained by adjusting the component content of the zeolite.

[conclusion]

Among the raw materials of ceramics, clays exhibit properties that improve plasticity and formability. If the content of clay is low, plasticity and moldability are low, but if the content of clay is high, it is important to mix a suitable amount because plasticity has a disadvantage in that shrinkage is increased. The component content of clay is preferably maintained in the range of 25 to 28%.

Next, feldspar is a component that acts as a flux, and since the firing temperature can be lowered, there is a problem in mixing a large amount, so an appropriate amount must be mixed. The component content of feldspar is preferably maintained within the range of 5 to 20%. If a large amount of feldspar is mixed, the surface may be smoothly changed like a glass surface, and thus the oil may not be applied. In the case of ceramics containing zeolite, it is suitable to mix a small amount (usually within 10%) when mixed with zeolite because Na content is high in zeolite.

If the silica is contained in a large amount, the strength is greatly increased, but since the workability is deteriorated, it should be controlled within the range of 10 to 30%, preferably around 15%.

Shrinkage during firing was mainly affected by clay, and zeolite did not appear to have a significant effect on shrinkage.

The strength decreased with increasing zeolite component content when using zeolite. The components that increased the strength were silica and pottery, and when the zeolite was contained in a large amount, the strength was weakened.

The whiteness increased as the component content of the zeolite increased, and the value increased when the degree of firing was matched with the firing temperature.

As the component content of zeolite increased, the weight of ceramics decreased markedly, and the degree of change in weight varies according to the firing temperature.

As mentioned above, according to the present invention, instead of the expensive raw materials used in the manufacture of ceramics, synthetic zeolites containing SiO ₂ and Al ₂ O ₃ which are main components of ceramic raw materials as main components and having a large amount of far-infrared emission useful for the human body are used. By adopting, new functional ceramic products can be produced, and inexpensive ceramic products can be obtained at a price.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.
