Separator and method for firing plurality of green sheet units using same

Abstract

The present disclosure relates to a separator and a method for firing a plurality of green sheet units using the same, the method enabling thin green sheets to be stacked and fired at a time. According to the method, after a green sheet assembly is formed by pressing a carbon separator having a protruding portion formed on one surface thereof so that the protruding portion comes into contact withboth surfaces of a green sheet, a plurality of green sheet assemblies are mounted on a firing setting member, the carbon separator is thermally decomposed at a set temperature and evaporated, and thenthe green sheet is fired and unit ceramic sheets are separated.

Description

Technical field [0001] The present invention relates to a partition and a method for firing a plurality of green sheet units using the partition, and more particularly to a method for stacking green sheet units by sandwiching a partition so that they can be fired at once Technology. Background technique [0002] In the case of manufacturing the fired ceramic sheet with a thinner thickness than the width and length, it is difficult to prevent the bending, cracking or breakage of the green sheet during the firing of the green sheet during the manufacturing process. In the case of stacking green sheets, when firing the green sheets in a single layer, it is difficult to produce a large number of ceramic sheets through a single firing process due to the limitation of the load-bearing area of ​​an expensive firing furnace that provides high temperature. [0003] In order to solve the above-mentioned problems, an attempt has recently been made to manufacture green sheets using a carrier ...

AI Technical Summary

Problems solved by technology

[0008] First, it is necessary to use a carrier film to form unevenness on green sheets with low mechanical strength, and then laminate green sheets with unevenness in multiple layers. Therefore, if the unevenness is not properly aligned during the lamination process, warping may occur after firing. , cracks or broken deformation

[0009] In addition, since green sheets having unevenness and low mechanical strength are handled in a physically stacked state, physical deformation easily occurs during handling, processing, or firing processes.

[0010] Also, if the concave and convex parts overlap, density differences will occur within the green sheet, so deformation such as warping, cracking, or chipping will occur during firing

[0011] In addition, since a carrier film with special unevenness is used, an expensive carrier film needs to be added, and a special process of removing the carrier film after forming the unevenness on the green sheet needs to be added, and the mechanical strength of the green sheet without the carrier film is reduced. Low, so it is not easy to handle and process
