Recently, the cremation culture is expanding rapidly. Normally, the cremation is made by dividing the remains of the cremated body, and putting them in the ashes and placing them in the ossuary. The ashes are the last appearances of the deceased. Therefore, the bereaved cherish the ashes, the last realities of the dead, and mourn through them. However, the ossuary where the ashes are enshrined is generally not close to home, so the bereaved families do not visit often.

For the bereaved, there is something dear to memorial to the dead. Things like pictures and photographs you used in your life will be such things. However, objects that were on the last road of the deceased, that is, objects that existed in the cremation while the body of the deceased was burned in the crematorium, could be more memorial to the deceased than any other object. Especially from the point of view of the person who believes in the existence of souls, it is possible to imagine that the objects that were with the dead at the crematory would have been the confession of the dead or the soul.

In addition, the heat treatment in the secondary firing step is preferably carried out at a temperature of at least 50 ~ 150 ℃ lower than the heating temperature in the primary firing step does not exceed 1,300 ℃.

In the memorial shape manufacturing method, the molding step may be performed by a dry molding method or a wet molding method. In the case of a dry forming method, the forming step may include mixing the raw material mixture with water and an adhesive and spraying it into a chamber having a temperature atmosphere of 200 to 300 ° C. to form granules of the raw material mixture; And it is preferable to include the granules of the raw material mixture in the mold die and to apply a pressure to make a primary shape. In the case of a wet molding method, the molding step comprises the steps of dissolving the raw material mixture in water to create a slip of the fluid state; Pouring the slip into the mold for molding the mold to remove moisture to form a molded body; And drying the molded body. In this case, it is preferable that the slip has a specific gravity of 1.7 to 2.1 g / cc.

In addition, in the memorial shape manufacturing method, the first firing step is to gradually increase the temperature to 400 ~ 600 ℃ for 4 to 10 hours and then maintain the temperature for 0.5 to 2 hours to degrease the shape A degreasing step for treatment; And it is preferable to include a sintering step to increase the temperature to 1,200 ~ 1,500 ℃ for 4 to 8 hours after the degreasing treatment and then maintain the temperature for 1 to 3 hours and then naturally cool.

Since the memorial shape according to the present invention is made to represent a change in plasticity in the process of incineration of the dead body in the crematorium, the bereaved family can be a thing having a deep connection with the dead and furthermore the soul of the dead soaks. You can imagine it as an old object. The memorial features are beautiful and easy to bring home. When the deceased is missed, the bereaved may be comforted in their hearts as they look at their home, and they may be able to reflect on their memories with the deceased. In this way the bereaved could find great comfort.

Therefore, the memorial shape may contribute to increase the makeup rate. In addition, it will contribute to the improvement of the funeral culture that wants to utilize the narrow territory efficiently.

The memorial features are plastically processed at high temperatures so they do not change over time and can be stored permanently.

The memorial shape manufacturing method is different from the general pottery or porcelain manufacturing method, considering the special conditions to complete the plastic processing in the toilet, it is a technology that is significantly different from the conventional ceramics or ceramic manufacturing method.

2 is a flowchart illustrating a process sequence of a method of manufacturing a memorial feature using a wet process according to the present invention.

The method of making a memorial shape is divided into a dry manufacturing method and a wet manufacturing method according to its molding method. First, a dry manufacturing method will be described.

(1) dry manufacturing method

1 is a flowchart showing a process sequence according to a dry manufacturing method.

First, the raw material of the memorial shape is mixed and pulverized to prepare a raw material mixture in powder form (step S10). The raw material mixture is made by mixing alumina (Al ₂ O ₃ ), clay, calcium carbonate (CaCO ₃ ), and talc (Mg ₃ Si ₄ O ₁₀ ). Their mixing ratio is 60 to 92% by weight of alumina (Al ₂ O ₃ ), 5 to 25% by weight of clay, 1 to 5% by weight of calcium carbonate (CaCO ₃ ), and talc (Mg ₃ Si ₄ O ₁₀ ) 2 It is preferable to set it as -10 weight%. It may further include silica (Si ₂ O ₃ ) as a component of the raw material mixture. The silica (Si ₂ O ₃ ) preferably comprises about 2 to 15% by weight based on the weight 100 of the raw material mixture consisting of the four materials.

Alumina is a mineral having a high melting point of about 2300 ° C. and having the highest fire resistance (No. SK40), and is a raw material serving as a basic skeleton of the memorial shape. The memorial shape is made by the main firing through secondary heating in the toilet after plasticity by primary sintering. The firing temperature is about 1,200 ° C. at a high temperature, and it is necessary to determine the mixing amount of each component so that there is no thermal shock and plastic deformation during the firing process. If the alumina is contained in less than 60% by weight, the desired strength cannot be obtained, it is difficult to cope with heat deformation or thermal shock, and the specific gravity of other constituent materials is large, thereby blocking pores in the first sintering, thereby causing glaze and pigment treatment. It is difficult and in excess of 92% by weight, not only is it difficult to fill the required content of other components, but it is also uneconomical because high temperature sintering is necessary.

Clay is composed of 32% by weight of alumina, 65% by weight of silica, and 3% by weight of clay. It has the highest viscosity in minerals and functions as an inorganic adhesive during molding and binds to the component during sintering. Calcium carbonate is used as a sintering accelerator and helps to develop pigment. Talc is a mixed mineral of magnesium and silica and provides sintering and thermal shock resistance. Quartzite is the main component of glass and is used as surface gloss and sintering accelerator.

In general, household containers and ornaments have been made by crushing ceramic raw materials or granite stored in nature. Ceramic materials in nature vary in composition, depending on the location of the ground and underground, even in the same mountain region, and it is difficult to meet the reproducibility of quality or poor plasticity conditions. In particular, since the sintering condition of the raw material mixture is not a general condition for sintering ceramics, but a condition of incineration of the body, the sintered shape should be sintered without any abnormality under very poor conditions and exhibit the best thermal shock resistance, fire resistance, and surface aesthetics. do. The combination of the raw materials and the mixing ratio of the raw materials of the present invention are made to satisfy these requirements, and the same purpose is to use 99.9% or more of the constituents of the raw material mixture.

The raw material mixture is pulverized, mixed and dispersed for about 24 hours using a ball mill, and processed according to the molding process. In order to disperse the raw materials, a peptising agent such as sodium phosphate or sodium silicate (a substance used to disperse precipitates or aggregates to form a stable colloidal solution) is added in an amount of about 0.3 to 1% by weight based on 100% by weight of the raw material mixture. It is preferable.

In addition, in the case of a cosmetic furnace in which the incineration temperature (secondary heating temperature of the memorial shape of the memorial shape) for the makeup and technical makeup of the cosmetic furnace is sharply increased, magnesium oxide (MgO) 1 to 3% by weight based on 100% by weight of the raw material mixture. And at least one of titanium oxide (TiO ₂ ) 3 to 10% by weight is further added to the raw material mixture. Magnesium oxide is a component that deteriorates the thermal conductivity by cutting off the growth of particles. If the price is cheap, but more than 3% by weight, the wet material is agglomerated due to the pozzolanic phenomenon, making it difficult to disperse. It is preferable to use titanium oxide when it is no longer needed. Since titanium oxide is difficult to bond with alumina, it is difficult to connect grain growth, but has a disadvantage of high price.

Next, the process of drying a raw material mixture is performed (step S12). In order to make the memorial shape dry form, it is necessary to maintain the exact density (1.6-2.3 g / cm 3) of the raw material to be produced, and for this purpose, it is preferable to make the raw material mixture into spherical granules. To do this, prepare a raw material by combining the raw material mixture with water and an organic adhesive such as a PVA adhesive, and then spray the raw material combination into a chamber that maintains a heat of 200-300 ° C., approximately # 40 by air exchange in the air. Spherical granules of size # 150 mesh are produced.

After making the raw material mixture granules, the memorial shape is molded using it (step S14). Specifically, the primary product of the desired memorial shape by applying an appropriate amount of granules of the raw material mixture to a mold mold made of several special steels having the opposite shape of the desired memorial shape and applying a high pressure (600Kg / cm 2 to 1,200Kg / cm 2) This is molded. The molded article may have burrs at the joints of several molds depending on the shape. In such a case, the burrs are removed to form a beautiful look.

The memorial shaped body is made into the final result after two predetermined processings.

First, the memorial shaped article is subjected to primary plastic working (step S16). In the primary firing, degreasing and plastic working are performed sequentially. Put the memorial shape into the heating furnace and gradually increase the temperature from 0 to 50 ° C to 400 to 600 ° C for 4 to 10 hours, and then maintain the temperature at 0.5 to 2 hours for degreasing treatment of the shape. Subsequently, the temperature is raised to 1,200 to 1,500 ° C. for 4 to 8 hours, the temperature is maintained for 1 to 3 hours, and then cooled naturally to complete the primary firing.

The reason for degreasing the memorial shape is as follows. As mentioned earlier, water and organic adhesives (such as PVA) are added to the raw material mixture for shaping, and these materials vaporize when heated for firing. If the heating temperature is rapidly increased at that time, the memorial shaped body may blow rapidly in volume and cracks may occur. Therefore, it is necessary to give enough time for the organic matter remaining inside the memorial shaped body to be completely released between the shaped particles so as not to cause all the cracks. To this end, as mentioned above, the memorial shaped body is placed in a furnace and the internal temperature of the furnace is gradually raised from 4 to 10 ° C. to 400 to 600 ° C. (preferably 500 ° C.) for 4 to 10 hours. After the temperature is maintained for about 0.5 to 2 hours, this process is to degrease the organic matter present in the memorial shape.

The maximum temperature of the primary firing process is carried out within the temperature range of 1,200 ~ 1,500 ° C, preferably about 50 ~ 150 ° C higher than the temperature of the cremator when the body is cremated (this is the secondary firing temperature). More preferably, the temperature is about 100 ° C. or higher. For example, when the incineration temperature of the cremation furnace during the cremation is 1,200 ° C., the primary plastic working temperature is 1,250 to 1,350 ° C., more preferably 1,300 ° C. If the firing is higher than this temperature, there is a disadvantage in that the manufacturing cost increases, for example, at a temperature above 1,500 ° C., the pore distribution ratio of the calcined memorial shape is only about 1 to 3%, which is not preferable. In other words, it is disadvantageous for economics and thermal shock.

The first firing memorial shape is in a state of microcrystallization (calcination) of about 5 to 15%, that is, in a state in which pores are formed in about 5 to 15% of the total volume. The state is composed of 85-95% of the combination of each raw material has a sufficient strength desired, there is no loosening even if put in water. In addition, since numerous pores are formed in the first calcined memorial shape to absorb some moisture, glaze treatment, color processing, or engraved character processing can be facilitated. The pores also function to absorb thermal shocks and other shocks during rapid temperature rise and adverse conditions during heating for secondary plastic processing in a toilet.

In this way, the heating temperature of the primary sintering process is about 50 ~ 150 ℃ higher than the secondary sintering temperature in the toilet, so as to be safe for shrinkage or thermal deformation to occur in the secondary firing.

After the primary plastic processing, the memorial shape is subjected to surface treatment using glaze, pigment, etc. (step S18) The purpose of the surface treatment is to improve the aesthetics and three-dimensional appearance of the primary fired shape. Glaze polishes and enhances the surface of the memorial feature, and the pigment paints and paints the desired text, picture, or color on the surface of the feature, using either glaze and pigment separately, or a mixture of both. Could be

Glazes may be selected from commercially available glazes in consideration of the primary and secondary firing temperatures. Pigments for ceramics use metal oxides, and representative examples thereof include cobalt (blue) manganese (black), iron oxide (brown), nickel and chromium (blue), titanium and zirconium (yellow), strodium and zinc. have.

Since the first calcined memorial feature does not have a high absolute porosity, coatings of surface treatment agents such as glazes and pigments may flow out of the shape.In order to prevent this, an organic adhesive such as PVA may be applied to the surface treatment agent. It is preferable to further include about 0.02 to 0.1% by weight relative to the weight%. If the amount of PVA is added, the fluidity is low, making it difficult to absorb glazes or pigments into the pores. Considering that the PVA has a thermal curing temperature of about 250 ° C., the PVA is heated to a temperature of about 250 ° C. to 350 ° C., preferably 300 ° C., so that the surface treating agent is thermally cured. This thermosetting facilitates the movement and handling of memorial features and does not dissolve in water.

This process completes the primary product of the memorial feature. The memorial shape of the primary product is put together with the body in the toilet and heated to the body makeup temperature to complete the firing process and color is developed by the surface treatment agent applied to the surface (step S20).

In general, incinerators (cosmetics) of the cremation are generally known to be heated at a temperature of about 1,200 ° C. for about 1 hour using electricity and maintained for about 1 hour. In that case, a rapid temperature rise of 20 ° C. or more occurs per minute, and such steep temperature rise generally causes ceramics or glass types to be damaged by thermal shock. However, in the memorial shape according to the present invention, the main component is alumina, which is a very high temperature refractory having a melting point of about 2,300 ° C., and is sintered at a temperature of about 50 to 150 ° C. higher than the sintering temperature of the toilet in the first firing process. Since the particles are bonded to each other and absorb the heat transfer and thermal shock by the pores connected between the particles, the shape change or damage due to the secondary plastic processing in the toilet does not occur. In addition, glazes and pigments thinly applied to the surface are melted and developed, for example, at 1,200 ° C. to enhance the surface strength.

Two methods of sintering of pottery and earthenware are oxidative sintering and reduction sintering. And the finished color of the glaze and pigment applied to the surface of pottery, etc. is sintered oxide (sintering carried out under forced air atmosphere with oxygen or external air between 800 ~ 1000 ℃) or reduction sintering (nitrogen, argon, or heating furnace) Incineration and sintering may be carried out together with a material that requires a large amount of oxygen for sintering, and the sintering may be performed in an atmosphere without or with oxygen).

The same applies to the finished color of the surface treatment agent applied to the surface of the memorial object. Oxidation and sintering methods in which oxygen is continuously introduced into a toilet by forced air blowing oxidize glazes, pigments (metal oxides), and the like, causing poor color development. Reduction sintering prevents oxygen from entering the toilet and inhibits oxidation, thereby brightening the color or surface. In the case of the present invention, the atmosphere of the secondary firing in the crematorium blocks the air from entering into the crematorium from the outside and exhausts the oxygen in the crematorium as the body and the tube are burned therein to naturally reduce the atmosphere. That is, the secondary sintering conditions in the toilet are reduced and sintered by the incineration contents (corpses and pipes), and the abnormal color development and the temperature difference due to the soot from the incineration contents and the sparks and dust swirling in the toilet. It is made of a memorial shape having the aesthetic sense of the surface.

Secondary plastic processing is performed until all the body incineration in the crematory is completed, and the firing is completed. The memorial feature is collected with the ashes.

Through the above process, the memorial figure keeps the last process of the dead body's return from nature to the end from side to end, thus providing room for imagining that the soul of the dead is transferred to the memorial image. Thus, the memorial image can be a symbol of the deceased to the bereaved and a vehicle for him. The tribute can be taken out of the cremation to comfort the family and always placed next to each other.

(2) wet manufacturing method

Next, FIG. 2 shows a process sequence of a method of manufacturing a memorial feature using the wet process according to the present invention.

The wet manufacturing method differs from the dry manufacturing method only in the method of forming the memorial feature, but the rest of the process, that is, the raw material mixture combination and pulverization (step S10), the primary firing of the memorial feature (step S16), and the surface of the first calcined memorial feature Application of glazes and pigments (step S18), and the second firing of the memorial shape (steps S20, S22) in the cremator are the same as the dry manufacturing method.

The molding of the memorial shape according to the wet manufacturing method is performed by dissolving the raw material mixture in water to make a fluidized slip, and then pouring the slip on the plaster mold for forming the shape to remove moisture to form a molded product, and drying the molded product. Is done through. This will be described in detail as follows.

First, the raw material mixture powder prepared in step S10 is released in water to make a slip (step S30). When making a slip it is necessary to adjust its viscosity and concentration accordingly. Viscosity is the binding force of each material composed. As the main raw material of the memorial shape, alumina, which is a super refractory material, has a small viscosity and precipitates, and thus, clay (alumina 30% silica 60% other properties and good viscosity) is mixed with this to use clay viscosity. As the particle size is smaller, the surface area is increased to increase the viscosity, and thus, it is necessary to precisely control the raw material combination grinding.

And if the amount of water injected for fluidity is small, the viscous force rises but the surface state of the memorial shape worsens and the strength drops. On the other hand, when there is much water, the plaster mold becomes wet and water absorption becomes difficult, and the thickness of the memorial molded body becomes thin. Therefore, the specific gravity of the slip is appropriately adjusted within the range of 1.7 g / cc to 2.1 g / cc according to the shape of the memorial shape. In addition, in order to prevent aggregation and precipitation of each particle, as a dispersant (peptide), it is adjusted to PH9 to 11 with basic substances such as sodium silicate, hexameta and the like.

After the slip is prepared, injection casting (slip casting) is made to form a memorial shape of a desired shape (step S32). Injection molding is achieved by pouring the slip into the plaster mold and drying it by removing moisture from the slip. Injection molding is usually complex in shape and used in small quantities in multiple varieties. Injection molding is most often used to produce three-dimensional shaped bodies. After the viscosity-adjusted slip is poured into the plaster mold and moisture is absorbed into the plaster, a memorial shape of a desired shape is formed.

The molded product thus contains about 25% of residual moisture, which is rapidly dried, causing cracks or distortions. Therefore, while maintaining the humidity in the drying room 95% or more while heating to less than 80 degrees heat-drying for about 10 hours, then gradually cools to remove the humidity.

Through this process, a molded article of the memorial shape is made, and the desired memorial shape can be made through the primary firing, the coating of the glaze and the pigment, and the second firing process in the cosmetic furnace.

The present invention can be used to make a shape that can remembrance the dead through makeup.
