Abstract
본 발명은 벌집형상의 허니콤 구조체 제조방법에 관한 것으로, 중합체 스펀지를 소정의 형상으로 가공하여 예비 성형체를 제공하는 단계와, 워터 제트 가공으로 예비 성형체에 셀을 형성하는 단계와, 셀이 형성된 예비 성형체를 건조시키는 단계와, 미세분말 상태의 성형재료에 경합제를 첨가하여 된 슬러리를 제공하는 단계와, 상기 슬러리에 건조된 예비 성형체를 침지하여 예비 성형체에 슬러리를 코팅하는 단계와, 슬러리가 코팅된 상기 예비성형체를 건조시키는 단계와, 예비 성형체 및 결합제를 고열로 제거하여 성형재료로 이루어진 허니콤 구조체를 형성하는 단계와, 상기 허니콤 구조체를 소결하는 단계로 이루어지는 것을 특징으로 한느 허니콤 구조체를 제조함으로써 압출다이가 불필요하여 고가의 다이 제작비용이 불필요하여 제작 비용을 줄일 수 있고 건조시 깨짐방지용으로 사용되는 결합제의 사용량이 줄거나 불필요하여 소결후의 기계적 강도가 증가된다. 또한 셀의 형상을 원형으로 형성하여 소결시 옹력 집중현상을 제거함으로써 기계적, 열적강도를 증가시킬 수 있고 소결수축과 변형을 감소시킬 수 있으며, 작용 표면적이 증가하여 정화효율 및 유체 흐름을 향상시킬 수 있다.The present invention relates to a method of manufacturing a honeycomb honeycomb structure, comprising the steps of: providing a preform by processing a polymer sponge into a predetermined shape; forming a cell in the preform by water jet processing; Drying the molded body, providing a slurry obtained by adding a competitive agent to the molding material in a fine powder state, immersing the dried preform into the slurry and coating the slurry on the preform, and coating the slurry Drying the preform, and removing the preform and the binder at a high temperature to form a honeycomb structure made of a molding material, and sintering the honeycomb structure. This eliminates the need for an extrusion die and eliminates the need for expensive die making costs. The amount of the binder used to prevent breakage during drying is reduced or unnecessary, thereby increasing the mechanical strength after sintering. In addition, by forming the shape of the cell in a circular shape, it is possible to increase the mechanical and thermal strength by reducing the force concentration phenomenon during sintering, to reduce the sintering shrinkage and deformation, and to increase the working surface area to improve the purification efficiency and the fluid flow. have.
