Definitions
- the present invention relates to a method for manufacturing a honeycomb structure. More specifically, a honeycomb structure preferably used for a catalyst carrier utilizing a catalytic action such as an internal combustion engine, a pillar, a chemical reaction device, and a reformer for a fuel cell, or a filter for collecting fine particles in exhaust gas, etc.
- the present invention relates to a method for manufacturing a honeycomb structure which can be manufactured well and at low cost.
- An 82 cam structure is used in a catalyst carrier or a particulate filter of exhaust gas, particularly a diesel particulate filter, which utilizes a catalytic action of an internal combustion engine, a boiler, a chemical reaction device, and a reformer for a fuel cell. I have.
- the honeycomb structure used for such a purpose has a problem that the temperature distribution in the honeycomb structure becomes non-uniform due to a sudden change in the temperature of the exhaust gas or local heat generation, causing cracks in the structure. .
- a filter hereinafter referred to as "DPF"
- Type ceramic heat exchangers have been proposed. Still, a SAE paper 860,008 in 1996 discloses a ceramic honeycomb structure in which cordierite 82-cam segments are also joined with cordierite cement. Further, Japanese Patent Application Laid-Open No. Hei 8-282246 discloses a ceramic in which a honeycomb ceramic member is bonded at least three-dimensionally with an elastic sealing material comprising an inorganic fiber, an inorganic binder, an organic binder and inorganic particles. A honeycomb structure is disclosed.
- such a honeycomb structure forms a honeycomb segment in which a plurality of cells serving as a fluid flow path partitioned by a porous partition wall functioning as a filter are arranged side by side in the central axis direction. It is manufactured by integrating a plurality of honeycomb segments to form a rough 82 cam structure, and processing the outer periphery into a predetermined shape. Since the honeycomb structure manufactured in this manner is used by being housed in a metal can or the like, it needs to be processed into an outer peripheral shape corresponding to the internal shape of the metal can or the like.
- a method of manufacturing the 82 cam structure by processing the outer periphery of such a rough honeycomb structure a method of processing with a grinder, for example, a cam grinder, a cylindrical grinder, or the like is known.
- a method of manufacturing a honeycomb structure by shaving a porous ceramic material into various sizes and shapes using a grinding member having a grindstone provided on a circumferential portion of a disk, and NC using a computer A method has been proposed for producing honeycomb structures of various shapes by controlling the position of a grinding member in synchronization with the rotation of a porous ceramic material under the control of Numerical Control 1). 0 0 1-1 9 1 2 4 0 gazette).
- the object to be ground (object to be processed) is a rough honeycomb structure 102 in which a plurality of honeycomb segments 101 are integrated
- a grinder for example, a cam grinder, a cylindrical grinder, or the like
- the rotating direction of the grindstone 103 becomes the honeycomb segment 1 constituting the rough honeycomb structure 102. Since the honeycomb surface 101 is peeled off at the joining surface 104 of the 01 and the coarse honeycomb structure 102 is broken by the peeling, the processing speed of the rough 82-cam structure 100 Efficient, constrained to the point where damage does not occur There was a problem that was not.
- the grinding between the grinding wheel 103 and the corner of the rough honeycomb structure 102 is performed.
- the probability of damage to the rough honeycomb structure 102 increased due to the impact at that time.
- the object to be ground is a porous ceramic material and the processing resistance due to its hardness is large, the wear speed of the grindstone 103 is high (the life as a tool is short), which is not advantageous in cost. There was a problem.
- the present invention has been made in view of the above problems, and has a catalyst carrier or a filter for collecting particulates in exhaust gas utilizing a catalytic action of an internal combustion engine, a boiler, a chemical reaction device, a fuel cell reformer, and the like.
