Abstract: front page image
(EN)Disclosed is a method for inspecting for defects of a green honeycomb compact (100) that has partitions (112) forming a plurality of ducts (110) extending parallel to each other and that has a sealing section (114) that closes the upper ends of a subset of the plurality of ducts (110) and the bottom ends of the remainder of the ducts (110). The method is provided with a step for applying pressure by means of gas on the bottom ends of the plurality of ducts (110), and a step for visualizing the distribution of the rate of gas deflection at the vicinity of the upper ends of the plurality of ducts (110).
(FR)L'invention concerne un procédé permettant d'inspecter des défauts d'un comprimé en nid d'abeilles vert (100) qui présente des partitions (112) formant plusieurs conduites (110) s'étendant parallèles les unes aux autres et qui a une section d'étanchéité (114) qui ferme les extrémités supérieures d'un sous ensemble des conduites (110) et les extrémités inférieures des conduites (110)restantes. Le procédé consiste à appliquer une pression au moyen des gaz sur les extrémités inférieures des conduites (110), et à visualiser la distribution du débit de déflexion des gaz à proximité des extrémités supérieures des conduites (110).
(JA) 互いに平行に伸びる複数の流路110を形成する隔壁112、及び、複数の流路110の内の一部の上端及び残部の下端を閉鎖する封口部114を有するグリーンハニカム成形体100の欠陥を検査する方法である。複数の流路110の下端に対してガスによる圧力を印加する工程と、複数の流路110の上端近傍のガス屈折率の分布を可視化する工程と、を備える。
