MANUFACTURING METHOD FOR CERAMIC HONEYCOMB FILTER
To provide a manufacturing method for a ceramic honeycomb filter, capable of preventing occurrence of mesh-sealing defect when forming a mesh-sealing part by filling a mesh-sealing material in a process of forming a mesh-sealing part to a ceramic honeycomb structure and capable of recognizing a flow path position to be sealed by an imaging device when opening a through-hole on a film.SOLUTION: There is provided a method for manufacturing a ceramic honeycomb filter by forming a mesh-sealing part 5a to a prescribed flow path end part of a ceramic honeycomb structure comprising numerous flow paths partitioned by a porous barrier 2. The mesh-sealing part is formed by: sticking a film on the edge face of the above structure; deciding a flow path position for forming the mesh-sealing part by imaging of an imaging device; forming a through-hole on the film of the above flow path position; filling the flow path end part with a mesh-sealing slurry from the through-hole; and drying the filled slurry. The method is characterized in that the average transmittance of a light having a wave length of 480 to 590 nm measured using the integrating sphere of the film is 50% or more but 88% or less.SELECTED DRAWING: Figure 1(a)
【課題】セラミックハニカム構造体に目封止部を形成する工程において、目封止材を詰めて目封止部を形成する際の目封止不良の発生を抑え、フィルムに貫通孔を開ける際、目封止すべき流路の位置を撮像装置で認識できるセラミックハニカムフィルタの製造方法を提供する。【解決手段】多孔質の隔壁２で仕切られた多数の流路からなるセラミックハニカム構造体の所定の流路端部に目封止部５ａを形成してセラミックハニカムフィルタを製造する方法であって、目封止部の形成は、セラミックハニカム構造体の端面にフィルムを貼付し、撮像装置の撮像により目封止部を形成すべき流路位置を決定し、目封止部を形成すべき流路位置のフィルムに貫通孔を形成し、貫通孔から目封止材スラリーを流路端部に充填し、充填した目封止材スラリーを乾燥して行い、前記フィルムの積分球を用いて測定される波長480〜590nmの光の平均透過率が50〜88%であることを特徴とする。【選択図】図１（ａ）
