| titleOfInvention | Honeycomb body and Vefahren for the production thereof |
| abstract | A honeycomb structural body (20) comprising: a porous ceramic separator section (22) forming and separating a plurality of cells (23) each serving as a flow path for a fluid; wherein, in the separation section (22), the average pore diameter is 10 to 20 μm, and the wet area ratio R (= S / V), which is the ratio of the wet area S of the pores to the volume V of the separation section, is 0.000239 μm -1 or more is, wherein the wet area ratio R of the separation section (22) is calculated using the three-dimensional voxel data (60) obtained by performing a CT scan of the separation section (22), wherein first, the separation thickness direction of the separation portion (22) is regarded as the X direction, the axis direction of the cell (23) is regarded as the Y direction, and the plane XY is regarded as the image cross section, next, the CT scan is performed on the separating section (22) for taking an image thereof while the image cross section in the Z direction orthogonal to the XY direction is shifted so as to obtain a plurality of image data, and based on these image data, the voxel data (Fig. 60), wherein the resolution of the X, Y, and Z directions is set to 1.2 μm, and the resulting cubic body having a side length of 1.2 μm is the smallest unit of the three-dimensional voxel data (60) that is, a voxel, moreover, even if the image data of the image cross section obtained by the CT scan is non-thickness plane data in the Z direction, the image cross sections are each regarded as an image cross section having a thickness equivalent to the interval (1.2 μm) in the Z direction between the image cross sections that is, each two-dimensional pixel of the image data is considered as a cubic body (voxel) with a side length of 1.2 μm, the size of the voxel data (60) as a rectangular parallelepiped with a length of 300 μm (= 1.2 μm × 250 voxels) in the X direction, a length of 480 μm (= 1.2 μm × 400 voxels) in Y Direction and a length of 480 microns (= 1.2 microns × 400 voxels) is considered in the Z direction, the position of each voxel is represented by the coordinates X, Y, Z (where a scale unit corresponds to the coordinate of 1.2 μm, which is the length of one side of the voxel), and a space voxel representing a space (pore) is distinguished of an object voxel representing an object, wherein the voxel of space is distinguished from the object voxel by a binary treatment using the density value method described below: a plurality of image data obtained by the CT scan are brightness data of each (X, Y, Z) coordinate, and based on these brightness data, the histogram of brightness of all coordinates (all pixels of the plural image data) is formed; then, the brightness of the portion (valley) to be recognized between two peaks in the histogram is set as the threshold, and the brightness of each coordinate is binarized, whether it is larger or smaller than the threshold, thereby each voxel becomes each Coordinate, whether it is a space voxel or an object voxel; Next, using this voxel data (60), the volume V of the separation section (22) and the wet area S of the pores are calculated as follows: the volume V is considered as the volume of all voxels of the voxel data (60), that is, the volume V is set at 69,120,000 μm 3 (= 300 μm × 480 μm × 480 μm), and as the wet area S, all the boundary planes of the Voxel data (60) between the voxel and the object voxel (number of voxel data bounded planes (60)) x (area of a bounding plane) calculated, the area of a bounding plane being 1.44 μm 2 (1.2 μm x 1.2 μm ) is; and next, from the thus calculated volume V and the wet region S, the wet area ratio R (= S / V) [μm -1 ] is calculated; provided that when the separation thickness of the separation section (22) is less than 300 μm, voxel data having the same volume V as described above is used. |
