Technical field
The present invention relates to the manufacture method of pottery, relate in particular under being shaped management quality well, be suitable for making the manufacture method of the pottery of stabilizing quality with the state of base soil.
Background technology
The structure that is made of pottery is in aspect extensive uses such as filter, catalyst carriers, particularly as the waste gas purification of internal combustion engines such as gasoline engine, diesel engine, burner with or exhaust-gas treatment be widely used with catalyst carrier, filter etc.Because from exhaust gas of internal combustion engines such as diesel engine, what contain a large amount of reasons that becomes environmental pollution is the particulate matter (particle-like substance) of main component with carbon, so in these gas extraction system, can carry the filter that is used for trap particulate matter.
Generally, the filter that is used for such purpose, use ceramic honeycomb structural body, shown in Fig. 3 (a) and Fig. 3 (b), this structure has a plurality of holes lattice of being separated by porous matter next door 17 (opening) 9 that connect on direction of principal axis, the end of the end of specific hole lattice 19a is sealed at these hole lattice 19 inner mouth-sealed portions 21 that are made of enclosed material of filling, and is similarly sealed by mouth-sealed portion 21 in the end of the other end of the opposition side of specific hole lattice 19a for remaining hole lattice 19b.
Waste gas flows into to inside from end face 13 beginnings by an end of such filter that honeycomb structured body constituted, and after the particulate matter that is contained in the gas etc. is removed, flows out from the end face 15 of the other end.Particularly, at first, waste gas flow into the hole lattice 19b that is not closed in inflow side end face 13 ends, is closed in outflow side end face 15 ends of this filter, by porous matter next door 17, move in inflow side end face 13 ends the hole lattice 19a that is closed, is not closed in outflow side end face 15 ends, lattice 19a is discharged from from this hole.At this moment next door 17 becomes filter course, thereby the particulate matter in the waste gas is caught by next door 17 and is deposited on the dividing plate 17.
Such pottery be ceramic materials such as cordierite, water and adhesive, pore-creating material etc. mixed, mixes after, by pug mill extruding ejection soil, this base soil is cut off according to desirable length, obtain being shaped and use base soil, the shaping that obtains is configured as honeycomb shape with base soil, drying, burns till and make.
In the manufacture method of in the past the structure that is made of pottery, the qualitative control with base soil of being shaped for example is to use by cutting into desirable length after the pug mill extruding, shaping is become certain volume with a part of severing of base soil and the sample strip that obtains.Specifically, the sample strip of intercepting certain volume is measured various weight, divided by the volume of sample strip, calculates density then.According to the density value of calculating like this, estimate the base soil (for example opening the 2003-327483 communique) that the back of mixing, mix is squeezed out by pug mill with reference to the spy.
