Description
본 발명은 3Ｄ프린터의 페이스트 조성물에 관한 것으로, 더욱 상세하게는 3Ｄ프린터로 백자(백색 자기)를 제작할 수 있는 3Ｄ프린터의 백자용 페이스트 조성물에 관한 것이다.The present invention relates to a paste composition for a 3D printer, and more particularly, to a paste composition for white porcelain of a 3D printer capable of producing white porcelain (white porcelain) with a 3D printer.
현재 주로 사용되고 있는 3D프린터는 FDM(Fused Deposition Modeling) 방식으로, 필라멘트가 주재료로 사용되고 있다. 공예분야에서는 LDM(Liquid Deposition Modeling) 방식을 활용한 3D프린터가 사용되면서 점토를 직접 출력하기에 이르렀다. 그러나 아직 프린터에 사용되는 재료인 점토에 대한 연구가 없어 고가의 3D프린터를 제대로 활용하지 못하고 철분을 많이 함유하여 점성이 좋은 청자점토와 옹기점토 등만 사용되고 있는 실정이다. 이 점토들은 유색점토로서 소성을 하면 철분의 영향으로 발색이 좋지 못하다. 따라서 색점토로 사용하거나 색유약을 쓰기에는 적절하지 못한 단점이 있다.Currently, the 3D printer mainly used is FDM (Fused Deposition Modeling), and filament is used as the main material. In the craft field, 3D printers using the LDM (Liquid Deposition Modeling) method have been used to directly print clay. However, there is no research on clay, which is a material used in printers, so expensive 3D printers cannot be used properly, and only celadon clay and pottery clay, which contain a lot of iron and have good viscosity, are used. These clays are colored clays, and when fired, the color development is not good due to the influence of iron. Therefore, there are disadvantages that are not suitable for use as colored clay or for use as a colored glaze.
기존의 백색 자기질 점토(백자점토)는 철분이 거의 없어 어떤 색의 안료나 유약에도 사용이 가능하여 표면을 장식하는 용도로 많이 사용되어 왔으나, 얇은 3D프린터의 노즐에서 나온 점토가 적층되기에는 점성이 너무 부족한 문제점이 있었다. 또한, 3D프린터로 항아리나 사발 등 가파른 각도(수평에서 45도 이하)의 경사가 있는 형태에는 출력이 어려운 문제점이 있었다. 출력 이후에는 건조와 소성과정에서 형태를 유지하는 것도 큰 어려움이 있었다.Existing white porcelain clay (white porcelain clay) has little iron and can be used for pigments or glazes of any color, so it has been widely used for surface decoration. There were too many problems. In addition, there was a problem in that it was difficult to output a shape with a steep angle (less than 45 degrees from the horizontal) such as a jar or bowl with a 3D printer. After printing, it was also very difficult to maintain the shape during drying and firing.
관련 선행기술로 한국 공개특허 제10-2021-0001423호의 3차원 본차이나 조형물 제조를 위한 3D 프린팅용 페이스트 조성물이 있다. 여기에는 점토외에 골회와 장석이 포함된 본차이나 소재 원료에 글리세린 등과 물과 에탄올이 혼합된 용매를 넣어 본차이나 조형물 제조를 위한 페이스트가 기술되어 있다. 그러나 상기 선행기술에는 점토를 특정할 수 있는 조성물 등이 전혀 개시되어 있지 않고, 점토에 포함되에 있을 함수량 외에 용매로 페이스트에 첨가되는 함수량이 전체의 21~29%(중량)를 차지해, 이를 통해서 상술한 기존 백자점토의 문제점을 해소할 만한 기술적 정보를 얻기 어렵다. As related prior art, Korean Patent Publication No. 10-2021-0001423 discloses a paste composition for 3D printing for manufacturing a three-dimensional bone china sculpture. Here, a paste for manufacturing bone china sculptures is described by adding a solvent mixed with glycerin, water, and ethanol to bone china material raw materials including bone ash and feldspar in addition to clay. However, the prior art does not disclose a composition capable of specifying clay at all, and the water content added to the paste as a solvent in addition to the water content to be contained in the clay accounts for 21 to 29% (by weight) of the total. It is difficult to obtain technical information that can solve the above-mentioned problems of the existing white porcelain clay.
이에 본 발명은 상술한 기존 백자점토의 문제점을 해소하여 다른 유색점토와 같이 점토용 3D프린터에 사용하기 적합한 3Ｄ프린터의 백자용 페이스트 조성물을 제공하고자 한다.Therefore, the present invention is to solve the above-mentioned problems of the existing white porcelain clay and to provide a paste composition for white porcelain of a 3D printer suitable for use in a 3D printer for clay like other colored clays.
상기 목적을 달성하기 위하여, 본 발명에 의한 3Ｄ프린터의 백자용 페이스트 조성물은 3Ｄ프린터의 백자 제작용 페이스트 조성물이되, 상기 페이스트에는 26~27%의 수분을 함유하는 백자점토; 및 상기 백자점토 100중량부에 대하여 무수에탄올(99.9%) 6~9중량부와 알루미나 0~20중량부가 포함된 것을 특징으로 한다.In order to achieve the above object, the paste composition for white porcelain of a 3D printer according to the present invention is a paste composition for making white porcelain of a 3D printer, and the paste includes white porcelain clay containing 26 to 27% of water; and 6 to 9 parts by weight of anhydrous ethanol (99.9%) and 0 to 20 parts by weight of alumina based on 100 parts by weight of the white porcelain clay.
상기 페이스트에는 상기 백자점토 100중량부에 대하여 규산소다 1~4중량부 더 포함될 수 있다.The paste may further include 1 to 4 parts by weight of sodium silicate based on 100 parts by weight of the white porcelain clay.
상기 페이스트에는 상기 백자점토 100중량부에 대하여 샤모트 1~2중량부와 글리세린 1~5중량부가 더 포함될 수 있다.The paste may further include 1 to 2 parts by weight of chamotte and 1 to 5 parts by weight of glycerin based on 100 parts by weight of the white porcelain clay.
상기 페이스트 조성물은 상기 페이스트를 105℃에서 48시간 건조했을 때, 전체 중량 중 SiO2 71.2%, TiO2 0.04%, K2O 1.52%, P2O5 0.02% 및 BaO 0.01%의 함량을 적어도 각각 포함할 수 있다.The paste composition contains at least 71.2% of SiO 2 , 0.04% of TiO 2 , 1.52% of K 2 O , 0.02% of P 2 O 5 , and 0.01% of BaO based on the total weight when the paste is dried at 105° C. for 48 hours. can include
상기 페이스트 조성물은 상기 페이스트를 105℃에서 48시간 건조했을 때, 전체 중량 중 Al2O3 19.2%, Fe2O3 0.36%, CaO 0.28%, MgO 0.09%, Na2O 1.44% 및 강열감량 5.83%를 더 포함할 수 있다.When the paste composition was dried at 105° C. for 48 hours, Al 2 O 3 19.2%, Fe 2 O 3 0.36%, CaO 0.28%, MgO 0.09%, Na 2 O 1.44% and loss on ignition of 5.83% based on the total weight. % may be further included.
본 발명은 26~27%의 수분을 함유하는 백자점토에 물은 전혀 첨가함이 없이 무수에탄올(99.9%)과 함께 알루미나, 규산소다, 샤모트 및/또는 글리세린을 적정량 첨가함으로써, 충분한 점성을 가져 제작할 기물에 가파른 각도가 있어도 무너짐 없이 적층 가능하며 소성 후에도 형태가 그대로 유지되어, 일반 점토용 3D프린터로 백자를 만들 수 있는 효과가 있다.The present invention has sufficient viscosity by adding an appropriate amount of alumina, sodium silicate, chamotte and/or glycerin together with anhydrous ethanol (99.9%) without adding water to white porcelain clay containing 26-27% of moisture. Even if the object has a steep angle, it can be stacked without collapsing, and the shape is maintained even after firing, so it has the effect of making white porcelain with a 3D printer for general clay.

이하, 첨부된 도면을 참조하며 본 발명의 바람직한 실시예에 대하여 설명한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
본 발명의 일 실시예에 의한 3Ｄ프린터의 백자용 페이스트 조성물은 3Ｄ프린터의 백자 제작용 페이스트 조성물로, 상기 페이스트에는 26~27%의 수분을 함유하는 백자점토; 및 상기 백자점토 100중량부에 대하여 무수에탄올(99.9%순도, 이하 단순히 에탄올이라 함) 6~9중량부와 알루미나 0~20중량부가 포함될 수 있다.A paste composition for white porcelain for a 3D printer according to an embodiment of the present invention is a paste composition for producing white porcelain for a 3D printer, and the paste includes white porcelain clay containing 26 to 27% of moisture; and 6 to 9 parts by weight of anhydrous ethanol (99.9% purity, hereinafter simply referred to as ethanol) and 0 to 20 parts by weight of alumina based on 100 parts by weight of the white porcelain clay.
여기서, 상기 백자점토는 공예분야에서 일반적으로 백자를 제작할 때 사용하는 점토일 수 있다. 본 실시예에서는 사용된 백자점토의 함수량을 측정하기 위하여 백자점토를 100g, 500g, 1kg로 나눠 건조기에 넣고 90℃에서 24시간 건조 후 무게를 측정하여, 아래 표 1과 같이 얻었다.Here, the white porcelain clay may be clay generally used in the craft field to produce white porcelain. In this Example, in order to measure the water content of the white porcelain clay used, the white porcelain clay was divided into 100g, 500g, and 1kg, put in a dryer, dried at 90 ° C. for 24 hours, and then weighed to obtain as shown in Table 1 below.
따라서, 본 실시예에서 사용된 백자점토는 26~27%의 수분을 함유할 수 있다.Therefore, the white porcelain clay used in this embodiment may contain 26 to 27% of moisture.
상기 백자점토에 먼저 물과 에탄올을 첨가했을 때 출력의 민감도, 형태 완성도 및 소성 후의 수축률과 형태 유지도를 살펴보았다.When water and ethanol were first added to the white porcelain clay, the output sensitivity, shape completeness, shrinkage rate and shape retention after firing were examined.
도 1은 상기 백자점토에 물과 에탄올을 첨가하여 출력한 결과(도 1a 내지 도 1d)와 재벌 소성한 결과(도 1e 내지 도 1h)를 보여준다. 여기서 재벌 소성한 결과는 통상의 소성과정과 같이, 산화소성으로 850℃로 초벌한 후에 1250℃에서 재벌 소성한 것이다(도 2와 도 3의 재벌 소성의 결과도 마찬가지임).Figure 1 shows the output results obtained by adding water and ethanol to the white porcelain clay (Figs. 1a to 1d) and the results of sintering (Figs. 1e to 1h). Here, the result of conglomerate firing is the same as in the normal firing process, priming at 850 ° C by oxidation firing and then firing at 1250 ° C (similar to the results of conglomeration firing in FIGS. 2 and 3).
먼저, 상기 백자점토에 물 1%(백자점토 100중량부에 대하여 물 1중량부)를 첨가해 실험을 진행하였으나, 수분이 부족하여 3Ｄ프린터의 실린더에서 튜브를 통과해 압출되기까지 어려움이 있었다. 상기 3Ｄ프린터는 EAZAO의 3D프린터를 사용하였다. First, an experiment was conducted by adding 1% water (1 part by weight of water with respect to 100 parts by weight of white porcelain clay) to the white porcelain clay, but there was difficulty in extruding from the cylinder of the 3D printer through the tube due to lack of moisture. The 3D printer used was EAZAO's 3D printer.
도 1a는 물 2%(백자점토 100중량부에 대하여 물 2중량부)를 첨가하여 출력한 결과를 보여주는데, 하단부 레이어 형성에 어려움이 있었고, 중단부, 상단부 모두 출력이 어려웠다. Figure 1a shows the result of printing with the addition of 2% water (2 parts by weight of water with respect to 100 parts by weight of white porcelain clay).
도 1b는 에탄올 6%(백자점토 100중량부에 대하여 에탄올 6중량부)를 첨가한 것인데, 형태는 문제없이 출력되나, 하단부가 갈라지고 출력물의 표면이 매끄럽지 않았다. Figure 1b shows the addition of 6% ethanol (6 parts by weight of ethanol with respect to 100 parts by weight of white porcelain clay), and the shape was printed without problems, but the lower part was cracked and the surface of the printed object was not smooth.
도 1c는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부)를 첨가한 것인데, 이 때도 형태는 문제없이 출력되나, 출력물의 하단부 절반이 석고판 베드에 가라앉았으며 이로 인해 출력물의 중심축에서 약간 어긋났다. Figure 1c shows the addition of 9% ethanol (9 parts by weight of ethanol with respect to 100 parts by weight of white porcelain clay). Even at this time, the shape was printed without problems, but the lower half of the print was sunk in the gypsum board bed, resulting in the center of the print. slightly off axis.
도 1d는 에탄올 12%(백자점토 100중량부에 대하여 에탄올 12중량부)를 첨가한 것인데, 이 때는 점토의 상태가 질어 적층 과정에서 온전한 형태를 유지하기 힘들었으며, 출력 후 건조가 되면서 하단부의 일부가 갈라져 떨어지는 문제가 있었다. 1d shows the addition of 12% ethanol (12 parts by weight of ethanol with respect to 100 parts by weight of white porcelain clay). At this time, it was difficult to maintain the integrity of the clay during the lamination process due to the poor condition of the clay, and as it dried after printing, part of the lower part There was a problem with the splitting off.
도 1e 내지 도 1h는 위에 있는 출력 도 1a 내지 도 1d를 각각 재벌 소성한 것으로, 출력 결과와 큰 형태의 변화는 없었다. 그러나, 가로(x와 y축)는 14.4% 감소, 높이(z축)는 19% 감소하였다. Figures 1e to 1h show outputs of Figures 1a to 1d above, respectively, and there was no significant change in shape from the output results. However, the width (x and y axes) decreased by 14.4% and the height (z axis) decreased by 19%.
도 1의 실험 결과로부터, 사용된 백자점토에 이미 26~27%의 수분을 함유하고 있어, 여기에 물만 더 추가할 경우 점성이 떨어져 출력시 적층에 어려움이 있었고, 물 대신 에탄올을 6~9중량부로 적절히 배합하는 것이 출력시 적층에 유리했고, 출력 후 하단부와 상단부의 경사각을 유지할 수 있음을 알 수 있었다. 그런데, 백자점토에 에탄올만을 추가하는 실험에서는 출력 후 건조와 소성과정에서 하단부 등이 일부 무너지고 갈라지는 현상이 발생하였다. 이러한 문제점을 해소하기 위하여, 에탄올외에 다른 첨가물을 넣어 실험을 계속했다.From the experimental results of FIG. 1, since the used white porcelain clay already contains 26 to 27% of moisture, when only water is added to it, the viscosity is low, making it difficult to laminate during printing. It was found that proper mixing with the parts was advantageous for lamination during printing, and that the inclination angle of the lower and upper parts could be maintained after printing. However, in the experiment in which only ethanol was added to the white porcelain clay, some of the lower part collapsed and cracked in the process of drying and firing after printing. In order to solve this problem, the experiment was continued by adding other additives in addition to ethanol.
도 2는 백자점토에 에탄올, 알루미나, 규산소다를 첨가하여 출력한 결과(도 2a 내지 도 2d)와 재벌 소성한 결과(도 2e 내지 도 2h)를 보여준다.Figure 2 shows the results obtained by adding ethanol, alumina, and sodium silicate to white porcelain clay (Figs. 2a to 2d) and firing ashes (Figs. 2e to 2h).
도 2a는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 알루미나 3%(백자점토 100중량부에 대하여 알루미나 3중량부)를 첨가한 것으로, 출력시 하단부의 형태가 완벽하게 나오지 않았지만, 백자점토에 에탄올만 첨가한 실험 보다 무너지는 정도가 약했다. 2a shows that 9% of ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 3% of alumina (3 parts by weight of alumina based on 100 parts by weight of white porcelain clay) are added, and the shape of the lower part does not appear perfectly when printed. However, the degree of collapse was weaker than the experiment in which only ethanol was added to the white porcelain clay.
도 2b는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 알루미나 6%(백자점토 100중량부에 대하여 알루미나 6중량부)를 첨가한 것으로, 처음 하단부를 형성하는 과정에서는 형태를 유지하는 듯하였으나 중단부를 형성하는 과정에서 하단부가 버티지 못해 무너졌다. 그러나 에탄올 9%의 출력물보다는 안정된 형태로 출력되었다. 2B shows that 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 6% alumina (6 parts by weight of alumina based on 100 parts by weight of white porcelain clay) are added. It seemed to be maintained, but in the process of forming the middle part, the lower part could not withstand and collapsed. However, it was printed in a stable form rather than the output of ethanol 9%.
도 2c는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부)와 규산소다 1%(백자점토 100중량부에 대하여 규산소다 1중량부)를 첨가한 것으로, 출력시 하단부, 중단부, 상단부의 비율이 일정하였으며 규산소다를 첨가함으로써 윤활제와 같은 역할을 하여 원활한 출력을 가능하게 하였다. Figure 2c shows the addition of 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 1% sodium silicate (1 part by weight of sodium silicate based on 100 parts by weight of white porcelain clay). The ratio of the upper part was constant, and sodium silicate was added to enable smooth output by acting as a lubricant.
도 2d는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 규산소다 2%(백자점토 100중량부에 대하여 규산소다 2중량부)를 첨가한 것으로, 도 2c와 거의 같은 결과를 보여주었다.FIG. 2d shows the results obtained by adding 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 2% sodium silicate (2 parts by weight of sodium silicate based on 100 parts by weight of white porcelain clay). showed
도 2e 내지 도 2h는 위에 있는 출력 도 2a 내지 도 2d를 각각 재벌 소성한 것으로, 출력 결과와 큰 형태의 변화는 없었고, 수축률도 도 1의 결과와 비슷했다.Figures 2e to 2h show the results of firing the outputs of Figures 2a to 2d above, respectively.
도 2의 실험 결과로부터, 백자점토에 에탄올만 넣는 것보다 알루미나나 규산소다를 적당량 첨가하는 것이 더 양호한 출력 결과물을 만들냈고, 건조와 소성과정에서도 형태 유지에 유리했다. 실험 결과와 알루미나와 규산소다의 특성으로, 에탄올이 6~9중량부 범위로 첨가될 때, 알루미나는 20중량부까지 및/또는 규산소다 1~4중량부로 배합할 수 있을 것으로 예측되었다. 알루미나가 20중량부를 초과하여 첨가될 경우는 페이스트의 힘, 즉 점성이 떨어져 출력시 적층에 어려움이 발생되고, 알루미나가 첨가되지 않을 경우는 도 1의 문제가 발생되므로, 도 2의 실험 결과로부터 규산소다 1~4중량부로 배합함이 바람직하다. 이는 도 2의 실험으로, 에탄올과 규산소다가 섞이면 두 성분의 결합으로 인해 특이한 응집효과가 생기며 압출과 적층이 원활해지는 현상을 발견하였기 때문이다. 알루미나와의 조합은 재료의 특성으로 인해 어느 정도의 압출과 적층에는 문제가 없었고 소성 후에도 형태가 단단하게 유지되는 장점이 있었지만 에탄올과 규산소다의 결합처럼 극적인 효과를 보여주지는 못했다. 상기 에탄올의 배합범위(6~9중량부)에서 규산소다 1~4중량부로 배합함이 바람직할 것이나, 도 2의 실험 결과로 볼 때, 에탄올 9중량부와 규산소다를 1중량부로 첨가하는 것이 최적의 결과물을 만들어 냈다. From the experimental results of FIG. 2, adding an appropriate amount of alumina or sodium silicate to the white porcelain clay produced better output results than adding ethanol alone, and it was advantageous to maintain the shape during drying and firing. From the experimental results and the characteristics of alumina and sodium silicate, it was predicted that when ethanol was added in the range of 6 to 9 parts by weight, alumina could be blended with up to 20 parts by weight and/or sodium silicate with 1 to 4 parts by weight. When alumina is added in excess of 20 parts by weight, the strength of the paste, that is, the viscosity, decreases, resulting in difficulties in lamination during output, and when alumina is not added, the problem of FIG. 1 occurs. It is preferable to mix with 1 to 4 parts by weight of soda. This is because, in the experiment of FIG. 2, it was found that when ethanol and sodium silicate are mixed, a unique coagulation effect occurs due to the combination of the two components, and extrusion and lamination become smooth. The combination with alumina had no problems with some degree of extrusion and lamination due to the characteristics of the material, and had the advantage of maintaining its shape firmly after firing, but it did not show dramatic effects like the combination of ethanol and sodium silicate. It is preferable to mix with 1 to 4 parts by weight of sodium silicate in the mixing range of ethanol (6 to 9 parts by weight), but from the experimental results of FIG. 2, it is preferable to add 9 parts by weight of ethanol and 1 part by weight of sodium silicate. produced optimal results.
추가적인 실험으로, 도 3과 같이, 에탄올에 샤모트, 글리세린을 첨가하여 출력과 소성 결과를 보았다. 도 3은 백자점토에 무수에탄올, 샤모트, 글리세린을 첨가하여 출력한 결과(도 3a 내지 도 3c)와 재벌 소성한 결과(도 3d 내지 도 3f)를 보여준다. 본 실험에서 샤모트는 40mesh(50목, 0.381mm)의 체로 거른 것을 사용했다. As an additional experiment, as shown in FIG. 3, chamotte and glycerin were added to ethanol to see output and firing results. Figure 3 shows the results of printing by adding anhydrous ethanol, chamotte, and glycerin to white porcelain clay (Figs. 3a to 3c) and firing the ashes (Figs. 3d to 3f). In this experiment, chamotte was used through a sieve of 40 mesh (50 necks, 0.381 mm).
도 3a는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 샤모트 1%(백자점토 100중량부에 대하여 샤모트 1중량부)를 첨가한 것으로, 본 실험에서 사용한 3D 프린터의 노즐은 2 mm 이어서 출력은 문제없었고, 초기 적층도 잘 되었으나 상단부가 완성되기 전 하단부에서 갈라졌다. 3a shows the addition of 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 1% of chamotte (1 part by weight of chamotte based on 100 parts by weight of white porcelain clay). The nozzle of the 3D printer used in this experiment is Since it was 2 mm, there was no problem with the output, and the initial lamination was good, but the upper part was cracked at the lower part before it was completed.
도 3b는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 샤모트 2%(백자점토 100중량부에 대하여 샤모드 2중량부)를 첨가한 것으로, 하단부가 갈라지는 특징은 도 3a와 비슷하나 상단부 부분에서는 더 완성된 형태를 유지하였다. Figure 3b shows the addition of 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay) and 2% of chamotte (2 parts by weight of chamotte based on 100 parts by weight of white porcelain clay). It was similar, but maintained a more complete shape in the upper part.
도 3c는 에탄올 9%(백자점토 100중량부에 대하여 에탄올 9중량부), 샤모트 2%(백자점토 100중량부에 대하여 샤모트 2중량부), 글리세린 2%(백자점토 100중량부에 대하여 글리세린 2중량부)를 첨가한 것으로, 도 3a와 도 3b보다 전체적으로 완성된 형태를 보이지만 소성과정에서 하단부에 처짐 현상이 생겨 최적의 조합이라고 보기에는 무리가 있었다.3c shows 9% ethanol (9 parts by weight of ethanol based on 100 parts by weight of white porcelain clay), 2% chamotte (2 parts by weight of chamotte based on 100 parts by weight of white porcelain clay), 2% glycerin (glycerin 2 based on 100 parts by weight of white porcelain clay) weight part) was added, and although it shows a more complete shape than FIGS. 3a and 3b, sagging occurred at the lower end during the firing process, making it difficult to see it as an optimal combination.
도 3d 내지 도 3f는 위에 있는 출력 도 3a 내지 도 3c를 각각 재벌 소성한 것으로, 여기서도 출력 결과와 큰 형태의 변화는 없었고, 수축률도 도 1의 결과와 비슷했다.Figures 3d to 3f show the conglomerate firing of the outputs of Figures 3a to 3c, respectively, and there was no significant change in shape from the output results here, and the shrinkage rate was similar to that of Figure 1.
도 3의 결과로부터, 도 1의 문제점을 해소하기 위해, 에탄올에 샤모트를 일부 첨가하는 것이 소성과정을 거치며 형태를 유지하는데 더 유리함을 알 수 있었다. 또한, 에탄올에 샤모트가 1~2중량부로 첨가될 때, 글리세린을 1~5중량부로 함께 첨가함이 출력시 윤활작용으로 보다 완성된 형태를 이룰 것으로 예측되었다. 그러나 에탄올이 9중량부로 이미 첨가된 상황에서 글리세린을 5중량부 초과해 첨가하게 되면 페이스트가 너무 묽어 하단부나 상단부와 같이 급경사를 갖는 기물 형성에 오히려 장애가 될 수 있다. 도 3c에서, 출력시 전체적으로 완성된 형태를 보이지만 소성과정에서 하단부에 처짐 현상이 발생되는 문제점을 해소하기 위해서는, 도 2의 실험 결과를 참작하여 알루미나 및/또는 규산소다를 적당량 더 첨가하는 것이 바람직할 것으로 예측된다.From the results of FIG. 3, it can be seen that in order to solve the problem of FIG. 1, adding some chamotte to ethanol is more advantageous in maintaining the shape through the firing process. In addition, when 1 to 2 parts by weight of chamotte is added to ethanol, it is predicted that adding 1 to 5 parts by weight of glycerin together will achieve a more complete form due to lubricating action during output. However, if glycerin is added in excess of 5 parts by weight in a situation where 9 parts by weight of ethanol is already added, the paste is too thin and may rather be an obstacle to the formation of objects having a steep slope such as the lower end or the upper end. In FIG. 3C, in order to solve the problem of sagging at the lower end during the firing process, although the overall finished form is shown during output, it is preferable to add an appropriate amount of alumina and/or sodium silicate in consideration of the experimental results of FIG. 2. predicted to be
상술한 실험에서 가장 출력이 잘되어 경사진 하단부 및 상단부에 처짐이나 주져 앉음이 없고, 수축률도 10% 대로 최소화하며 건조 및 소성과정에서도 형태를 잘 유지하는 백자용 페이스트를 찾아 성분 분석을 하였다.In the above-mentioned experiment, the white porcelain paste that produced the best output, had no sagging or sagging at the inclined lower and upper ends, minimized shrinkage to the 10% level, and maintained its shape well during drying and firing was analyzed for its components.
