Preparation of structure for purifying exhaust gas
专利汇可以提供Preparation of structure for purifying exhaust gas专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a structure of which the mesh size is optionally adjusted, by a method wherein a foam body having a diameter larger than that of the structure is introduced into a cover member having a diameter same to that of the structure under pressure and a ceramic slurry is adhered to the pressed foam body to carry out drying and baking. CONSTITUTION:When a structure foam 10 having three-dimensional network structure is cut into a conical truncated shape and urethan foam 20 having mesh finer than that of the base body 10 is adhered to the side surface thereof as a reinforcing wall is inserted into a cover member having a diameter same to that of an objective structure under pressure, the large diameter part thereof is compressed more strongly and the mesh size thereof becomes finer toward the bottom part thereof. This foam body is immersed in a ceramic slurry along with the cover member to adhere the slurry to said foam body and dried and baked to obtain the structure of which the mesh size is continuously changed from an inlet side to an outlet side as shown in the first drawing. As described above, because the mesh size is changed by the compression ratio of the structure, a desired mesh size is obtained by selecting the shape of the structure.，下面是Preparation of structure for purifying exhaust gas专利的具体信息内容。
