ʻOi aku ka liʻiliʻi o ka ʻāpana, ʻoi aku ka kiʻekiʻe o ka keʻokeʻo.ʻOi aku ka ʻoi aku ka paʻakikī o ka wehe ʻana i ke kalapona, ʻoi aku ka maʻalahi o ke kalapona i loko o ka ʻāpana ʻaʻole maʻalahi e hoʻololi, e pili ana i ka keʻokeʻo o ka huahana calcined.Maikaʻi ka mea maka, nui ka ʻili, maʻalahi ke kalapona e wehe, maʻalahi ke kalapona e volatilize, a kiʻekiʻe ke keʻokeʻo o ka huahana calcined.

I ke kaʻina o ka calcining huahana keʻokeʻo, kaolin i ka lohi iho au me ka piʻi 'ana o ka calcination wela.Hoʻohālikelike ʻia me 900 ℃, 850 ℃ kaolin calcination, nā huahana kaolin ʻaʻole e wehe wale i ka wai aniani, hoʻonui i ka nui o ka pore, akā mālama pū nō hoʻi i ka flaky, keʻokeʻo kiʻekiʻe, pili i ka mahana calcination, hoʻemi i ke kumukūʻai kālā a me ka pollution kaiapuni, no laila ʻo 850 ℃ ka mahana calcination maikaʻi loa.

Hoʻonui ka keʻokeʻo o ka huahana me ka manawa mahana mau, akā lohi ke ʻano.Ke pōkole loa ka mahana, ʻaʻole maʻalahi ke kalapona i ka kaolin e wehe.Ma hope o 4 mau hola o ka mahana mau, liʻiliʻi ka decarburization a me ka dehydration o ka huahana, no laila e hoʻomaikaʻi ʻia ka keʻokeʻo o ka huahana, akā liʻiliʻi ka hoʻomaikaʻi.I mea e hoʻomaikaʻi ai i ka maikaʻi wela, ʻoi aku ka maikaʻi o ka mālama ʻana i ka mahana o ka huahana calcined no 4 mau hola

Ma ka hoʻohana ʻana i nā mea hoʻohui calcining like ʻole, ua maʻalahi ke kaʻina hana, hoʻemi ʻia ke kumukūʻai, a hoʻomaikaʻi nui ʻia ke keʻokeʻo o nā huahana calcined.I waena o lākou, ʻo ka sodium chloride ka mea hoʻohui maikaʻi loa.ʻO ka hoʻokomo ʻana i ka urea ma ke ʻano he intercalation agent e hoʻonui i ka keʻokeʻo o ka kaolin calcined

He hopena nui ka mana o ka lewa calcination i ka keʻokeʻo a me ka melemele o nā huahana calcined.No ka hoʻokō ʻana i nā pono o ka wehe ʻana o ka lanahu kaolin, calcination i ka oxidizing ea hopena i ka haʻahaʻa haʻahaʻa hao a me ke kumu kūʻai kiʻekiʻe, e alakaʻi i ka piʻi ʻana o ke kalapona a me ka yellowness o nā huahana kaolin.No laila, ʻo ka calcination ma 850 ℃ i ke kiʻekiʻe o ka mahana a me ka hoʻohaʻahaʻa ʻana i ka lewa hiki ke hōʻemi i ka hao haʻahaʻa a me ka hao kiʻekiʻe, e kāohi i ka lewa calcination, e hōʻemi i ka keʻokeʻo a hoʻomaikaʻi i ka melemele o nā huahana.
