Improvement in slip casting process for porcelain
Nobuaki KAMOCHI, Kana YAMASAKI
Saga Ceramics Research Laboratory
Slip casting is one of the main forming methods to make complex shaped porcelains in Hizen area.
However, depending on the shapes, a sink mark is generated on a thick part and a crack is generated in athin part. In this research, the influence of slip conditions to precision of products was evaluated. As aresult, the sink mark was effectively prevented even 20mm over thickness products and the cracks were
not occurred even in the thin products by effect of addition of a flocculant. 㻌㻌⭯ᆺ䛾ᨵⰋ䛰䛡䛷䛿ᑐᛂᅔ㞴䛺ᙧ≧䛾ᅽຊ㗪㎸䜏ᡂᙧ㻝㻚㻌 䛿䛨䜑䛻㻌㗪㎸䜏ᡂᙧ䛿⫧๓ᆅ༊䛻䛚䛡䜛☢ჾ䛾㔞⏘䛻䛚䛔䛶䜔䚸ᚑ᮶䛾᤼Ἶ㗪㎸䜏䛷䛿ᆺෆ䛷๭䜜䛶䛧䜎䛖䜘䛖䛺」
