DRYING METHOD FOR CERAMIC GREENWARE

摘要

The present invention is directed to a method comprising a) placing wet ceramic greenware body (36) on a carrying structure, and b) exposing the wet ceramic greenware body (36) to conditions such that the liquid carrier in the ceramic greenware body (36) is substantially removed; wherein the carrying structure contains a carrying sheet (28) comprising a material which, retains its shape under drying conditions, the carrying sheet (28) having two flat parallel faces and a plurality of walls (31) perpendicular to the flat parallel faces wherein the walls (31) form a plurality of flow passages (32) communicating between the two faces wherein the largest distance between any two walls (31) in the carrying sheet (28) is about 6 mm or less and the walls (31) have a sufficient thickness to support the wet ceramic greenware body (36) under drying conditions without deforming and the area of the flow passages (32) measured parallel to the two faces is from about 60 to about 90 percent by volume.
