- Example 1 For each of the honeycomb structures obtained in Example 1 and Comparative Example 1, at the bonding surface 7 in FIG. 6, at the 10 measurement points 11 indicated by circled numbers 1 to 10 The thickness of the adhesive layer was measured. Table 1 shows the measurement results. Measurement point 1 ⁇ ⁇ (D 6 ⁇ ⁇ average standard deviation Example 1 (with spacer) 0.79 0.78 0.78 0.81 0.79 0.81 0.81 0.80 0.80 0.78 0.80 0.013 Comparative example 1 (without spacer) 0.55 0.97 1.01 0.66 0.67 0.84 0.89 0.67 0.75 0.61 0.76 0.157
- the thickness of the adhesive layer can be made substantially equal to the thickness of the pole paper, that is, the desired thickness by interposing the pole paper as a spacer. Was. Also, there was very little variation between the measurement points, and the thickness of the adhesive layer could be kept constant.
- the two honeycomb segments obtained in the above manufacturing process the dimensions are 1 O mmX 1 O mmX 0.8 mm (thickness), 3% by mass of SiC and 23% by mass of silica sol , 2% by weight of inorganic auxiliary, 32% by weight of ceramic fiber, 4 sides of inorganic material, 40% by weight of SiC as adhesive, 20% by weight of silica sol, 1% by weight of inorganic auxiliary
- a ceramic adhesive composed of 30% by mass of ceramic fiber and 9% by mass of water was prepared.
- ceramic adhesive was applied to the side of the honeycomb segment, that is, the adhesive surface.
- a honeycomb structure in which two honeycomb segments were integrated was obtained by applying the agent, and arranging the inorganic material at four locations above and below the side surface, pressing and bonding and drying.
- Example 2 The same operation as in Example 2 was performed, except that no inorganic material serving as a spacer was used, to obtain a honeycomb structure.
- Measurement point 2 (4) 0 8 9 (10) Average standard deviation Example 2 (with spacer) 0.79 0.78 0.81 0.78 0.81 0.79 0.80 0.81 0.80 0.81 0.80 0.012
- the thickness of the adhesive layer can be made substantially equal to the thickness of the inorganic material, that is, the desired thickness by interposing the inorganic material which is the spacer. Was. Also, there was very little variation between the measurement points, and the thickness of the adhesive layer could be kept constant.
- honeycomb segments obtained by manufacturing the above honeycomb segment were prepared, and the adhesive used in Example 2 was used as a spacer forming agent. After placing it on a hot plate, place it on a hot plate with a 0.5 mm thick iron plate, as shown in Fig. 10, and heat it at about 160 ° C for about 6 seconds to solidify it. As shown in FIG. 7, four spacers fixed on the adhesive surface of the second cam segment were formed. When the thickness of this sensor was measured, it was within the range of 0.5 ⁇ 0.1 mm.
- Example 3 The same operation as in Example 3 was performed, except that the inorganic material serving as the spacer was not used, to obtain a honeycomb structure.
- Example 3 With respect to each of the honeycomb structures obtained in Example 3 and Comparative Example 3, at the bonding surface 7 in FIG. 6, at the 10 measurement points 11 indicated by numerals 1 to 10 circled. The thickness of the adhesive layer was measured. Table 3 shows the measurement results. In the honeycomb structure obtained in Example 3, the dispersion of the adhesive layer was kept at a predetermined thickness with little dispersion between measurement points by interposing an inorganic material as a spacer. I was able to. (Table 3)
- the honeycomb structure of the present invention since the spacers are arranged between the honeycomb segments, the thickness of the adhesive layer between the honeycomb segments can be set to a desired thickness and can be made uniform. It was possible to obtain a honeycomb structure with less accuracy defects. Further, by the manufacturing method of the present invention, a honeycomb structure having the above-mentioned effects could be easily produced. INDUSTRIAL APPLICABILITY
- the honeycomb structure of the present invention is suitably used for a catalyst carrier utilizing a catalytic action such as an internal combustion engine, a boiler, a chemical reaction device, a reformer for a fuel cell, or a filter for collecting particulates in exhaust gas. Can be.
