It can be seen that the bending strength increases as the amount of low-temperature firing glass powder added increases.
한편, 제2 단계에서 첨가되는 고분자 폴리머는, 폴리비닐알콜, 폴리비닐 아세테이트, 폴리에틸렌, 폴리비닐부티렌, 폴리프로필렌, 폴리염화비닐, 폴리 아크릴, 폴리 아크릴 아미드, 구아 검, 젤라틴 및 천연고무 중에서 선택된 하나 이상의 물질인 것이 바람직하며, 분산제는 습윤성 분산제인 것이 바람직하다. Meanwhile, the high molecular weight polymer added in the second step is preferably one or more substances selected from polyvinyl alcohol, polyvinyl acetate, polyethylene, polyvinyl butylene, polypropylene, polyvinyl chloride, polyacrylic, polyacrylamide, guar gum, gelatin, and natural rubber, and the dispersant is preferably a wetting dispersant.
제2 단계에서 제조되는 세라믹 과립의 평균 입경은 50∼1000㎛인 것이 바람직하다.It is preferable that the average particle size of the ceramic granules manufactured in the second step be 50 to 1000 μm.
한편, 제3 단계는, 세라믹 과립을 1축 또는 다축 가압하여 성형되며, 세라믹 흡습체를 원하는 형태로 압축 성형하는 단계이다. Meanwhile, the third step is a step of compressing and molding the ceramic absorbent into a desired shape by pressing the ceramic granules in one or multiple axes.
제4단계의 소결은 저온 소성용 글래스 분말의 적정 소성 온도에 맞추어 600∼1200℃ 온도 범위에서 이루어지는 것이 바람직하다. It is desirable that the sintering in the fourth stage be performed at a temperature range of 600 to 1200°C to match the appropriate sintering temperature of the glass powder for low-temperature sintering.
제4단계의 소결 과정을 거치면서,저온 소성용 글래스 분말의 표면 용융 및 넥킹 현상에 의해 세라믹 코어쉘 구조가 형성된다. 즉, 고강도 세라믹 흡습체는 1600℃ 이상의 고온 소성이 필요한 금속 이온과 결합된 실리케이트 분말에 저온 소성용 글래스 분말을 첨가함으로써, 상대적으로 낮은 600 ~ 1200℃의 온도에서 소결하여도 1Mpa 이상의 파괴 강도를 가진다는 장점이 있다. Through the sintering process of the fourth step, a ceramic core-shell structure is formed by the surface melting and necking phenomenon of the low-temperature sintering glass powder. That is, the high-strength ceramic moisture absorbent has the advantage of having a fracture strength of 1 MPa or more even when sintered at a relatively low temperature of 600 to 1200°C by adding low-temperature sintering glass powder to silicate powder combined with metal ions that require high-temperature sintering of 1600°C or higher.
한편, 실시예의 방법에 따라 제조된 고강도 세라믹 흡습체는, 에어로졸 발생장치에 설치되어 액상 흡수용으로 사용되거나, 담체용으로 사용될 수 있다. 또한 고강도를 유지하며 액체를 머금어야 하는 흡습체가 필요한 경우라면 어떠한 곳에든 적용할 수 있다. Meanwhile, the high-strength ceramic absorbent manufactured according to the method of the embodiment can be installed in an aerosol generating device and used for liquid absorption or as a carrier. In addition, it can be applied to any place where an absorbent that maintains high strength and can hold liquid is required.
