Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs.

1 is a flowchart illustrating a method of shaping an ash according to an embodiment of the present invention.

Referring to FIG. 1, the ash is pulverized as a fine powder, the fine powder is boiled in distilled water for 2 hours or more, and dried to remove impurities causing flaws during firing, thereby preparing ashes (100). For example, the impurity may be an alkaline component.

A slurry containing the ash, inorganic material and organic material is prepared (110).

The slurry may be prepared by mixing 30 to 60 weight (wt%) of ash, 10 to 30 weight (wt%) of an inorganic material and 20 to 50 weight (wt%) of an organic material with respect to 100 slurry.

Example Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Ash content 30 to 60 Less than 30 Greater than 60 40 to 70 20 to 50 Mineral content 10 to 30 20 to 40 5 to 15 20 to 40 10-20 Organic matter content 20 to 50 20 to 50 25 to 35 Less than 20 Greater than 50 characteristic Strength after shaping Great Great Great Can not be formed Great Deformation during firing none transform occur none - none Strength after firing Strong Strong Cracking - Cracking

Referring to Table 1, when the slurry is mixed with 30 to 60 weight (wt%) of ash, 10 to 30 weight (wt%) of inorganic material and 20 to 50 weight (wt%) of organic material with respect to slurry 100, It was found that the strength after shaping was excellent, there was no deformation at firing, and the strength after firing was strong.

The inorganic material may further include an inorganic additive. The inorganic additive may be selected from the group consisting of 50 to 80 wt% silicon dioxide, 1 to 5 wt% boron trioxide, 10 to 30 wt% sodium oxide, 1 to 5 wt% % Of calcium oxide, 3 to 15 wt% of calcium oxide and 1 to 10 wt% of aluminum oxide.

The inorganic material may include 50 to 80 wt% silicon dioxide, 1 to 5 wt% boron trioxide, 10 to 30 wt% sodium oxide, 1 to 5 wt% potassium oxide, calcium oxide 3 To 15 weight percent (wt%) and 1 to 10 weight percent (wt%) aluminum oxide may be added as an inorganic additive. For example, all inorganic additives mentioned above may be added to the inorganic material, and only some inorganic additives may be added. Alternatively, two or more kinds of inorganic additive having the same effect may be added to the inorganic material. This is because the effect of adding an inorganic additive having the same effect to two or more kinds of inorganic materials can be increased more than when one kind of inorganic additives is added to inorganic materials.

Silicon dioxide (SiO ₂ ) increases the transparency of glass, has high chemical resistance and small thermal expansion, and is effective in stabilizing glass. If the content of silicon dioxide (SiO 2) is less than 50 wt%, the effect of stabilization is not sufficient. If the content exceeds 80 wt%, the softening point tends to be high. Therefore, the content is preferably 50 to 80 wt%.

Boron trichloride (B ₂ O ₃ ) has the effect of reducing thermal expansion and softening point, increasing fluidity and stabilizing glass. If the content of boron trioxide (B ₂ O ₃ ) is less than 1 wt%, the effect is not sufficient and the thermal expansion coefficient increases. If the content exceeds 5 wt%, gelation of the slurry causes an increase in viscosity, , And the content is preferably 1 to 5 wt% (wt%).

Sodium oxide (Na ₂ O) plays a role in reducing the softening point of glass and increasing fluidity. If the content of sodium oxide (Na ₂ O) is less than 10 wt%, the viscosity of the glass increases and the fluidity decreases. If the content of sodium oxide (Na ₂ O) exceeds 30 wt%, the thermal expansion coefficient increases. Weight (wt%) is preferred.

Potassium oxide (K ₂ O) plays a role in reducing the softening point of glass, increasing fluidity and improving transparency. When the content of calcium oxide (K ₂ O) is less than 1wt% becomes larger, the viscosity of the glass decreases fluidity, and therefore the content of calcium oxide (K ₂ O) and if it exceeds 5wt% increase in the coefficient of thermal expansion, calcium oxide (K ₂ O) is more than 30 wt%, the thermal expansion coefficient is increased. Therefore, the content is preferably 1 to 5 wt%.

Calcium oxide (CaO) plays a role in reducing the softening point of glass and improving the strength. If the content of calcium oxide (CaO) is less than 3 wt%, the occurrence of crystallization, which is the cause of opacification, increases. When the content of calcium oxide (CaO) exceeds 15 wt%, the softening point increases and the thermal expansion coefficient increases. To 15 wt% (wt%).

Aluminum oxide (Al ₂ O ₃ ) plays a role in improving the transparency by suppressing the crystals generated during the cooling process, and is effective in stabilizing the glass and enhancing the chemical durability. If the content of aluminum oxide (Al ₂ O ₃ ) is less than 1 wt%, the effect is not sufficient. If the content of aluminum oxide (Al ₂ O ₃ ) exceeds 10 wt%, the softening point becomes high. wt%).

The organic material may be selected from the group consisting of polyvinyl alcohol, methyl cellulose, carboxymethyl cellulose, polyvinyl butyral, ethyl cellulose, polymethyl methacrylate, epoxy acrylate, uretane acrylate, polyester acrylate and the like according to a curing method such as hydrostatic pressing method, thermosetting method, thermoplastic method, , Acrylic emulsion, wax emulsion, polyethylene, poly vinyl chloride, polypropylene, polystyrene, polyacrylonitrile, acrylonitrile butadiene styrene, polymethyl methacrylate, phenol resin, amino resin, epoxy resin and unsaturated polyester. The above materials act as binders.

In addition to the above materials, dispersants, plasticizers, lubricants, and initiators may be added to the organic material.

The content of the binder, the dispersant, the plasticizer, the lubricant and the initiator is preferably 20 to 50 wt% (wt%) based on 100 wt% of the slurry.

Soft molding is performed 120 to create an ash mixture corresponding to the original shape of the ash. The concrete process of soft molding is as follows. After making a soft mold corresponding to the original shape of the ashes, put the slurry into a soft mold. The binder is then cured to make the slurry solid, and the soft mold removed. For example, the curing method can be cured by an hydrostatic pressing method, a thermosetting method, a thermoplastic method, or a photo-curing method depending on the curing characteristics of the organic material mixed in the slurry. Through such a process, it is possible to produce an ash mixture having the same shape as the asbestos circular shape.

The material of the soft mold may be urethane rubber, chloroprene rubber, silicone rubber, nitrile rubber and the like.

2 is a view for explaining a process of manufacturing a soft mold according to an embodiment of the present invention.

Referring to FIG. 2, a three-dimensional modeling of the ashes is performed (200). Based on the three-dimensional modeling, an original model of the ashes is produced using a printing or cutting method (210). Next, a soft mold is manufactured using the original model (220).

By doing so, it is possible to manufacture a soft mold capable of producing a model of the same shape as the original shape of the ash.

The binder contained in the ash mixture produced in the soft molding process is removed ('binder binder') (130). For example, a binder ('organic material') can be removed by maintaining a temperature of 200 ° C to 500 ° C.

The ash mixture is baked and densified (140). For example, it is possible to maintain the temperature of 800 ° C to 1000 ° C to make solid ash crystals.

The embodiments described above may be constructed by selectively combining all or a part of each embodiment so that various modifications can be made.

It should also be noted that the embodiments are for explanation purposes only, and not for the purpose of limitation.
