Kūkākūkā e pili ana i ka mana o ka glaze i nā hemahema pinhole o ka glaze piha

ʻO nā huahana glaze piha ke ʻano nui o ka ʻoihana tile ceramic home i nā makahiki he ʻumi i hala iho nei, a ʻo ka glaze pinhole defects ka mea maʻamau i ka hana ʻana i nā huahana glaze piha, a ʻo ia kekahi o nā hemahema hana i paʻakikī loa. pale aku, ka mea pololeipili i ka hopena maikaʻi o ka glaze o ka huahana a me ka helu maikaʻi o ka huahana i hoʻopau ʻia. Nui nā kumu e hoʻopōʻino ai i ka pinhole, e like me nā blanks, glazes, nā ʻāpana kaʻina hana a me nā ʻōnaehana puhi ahi, a me nā mea ʻē aʻe, a me nā glazes e pili ana i ka glaze piha a me ka glaze maka, ke aʻo nui nei kēia pepa i ka mana o ka hoʻokumu ʻana o ka maka glaze formula i nā hemahema pinhole, kūkākūkā i ka ka pilina ma waena o ka lākiō flux a me ka huina nui i loko o ke kumu me ka laulā kī a me ka laulā o ka noi, a me ka pilina ma waena o ke kiʻekiʻe wela mea lākiō a me ka huina leo, a kūkākūkā i ka hoʻonā i ka hoʻomalu wikiwiki a me ka pono a hoemi glaze pinhole defects.

Ua hoʻopau ʻia ka hoʻāʻo ʻana ma kahi ʻoihana keramika kaulana ma Qingyuan, ʻo ka lōʻihi o ka kiln he 325m, ʻo ka pōʻai ahi he 48min, ʻo ke apo wela he 1166-1168 °C, ua hoʻohana ʻia ka maka aniani ma ka ʻoki ʻana i ka glaze, a me ka glaze. ua hoʻohana ʻia e ke ʻano glaze no ka glaze piha, a ua helu ʻia ka helu o nā hemahema pinhole ma kahi o 400mm × 800mm. Hōʻike ʻia ke ʻano o ke kino ʻōmaʻomaʻo, ke aniani piha a me nā mea maka i hoʻohana ʻia no ka glaze i hoʻohana ʻia i ka hoʻāʻo ʻana ma ka Papa 1.

2.1 Ho'āʻo i ka hopena o ka ratio flux a me ka lākiō o ka lepo kuni a me ka alumini ahi ma luna o nā pinhole

Kumu: albite 12, potassium feldspar 31, quartz 20, pahi ʻea honua 10, alumini puhi 22, frit haʻahaʻa haʻahaʻa 3, nepheline 7, zirconium silicate 9.

Hoʻolālā ʻia kahi hoʻāʻo ʻelua kumu 3-level ma ke kumu o ka huinahā mua, me ka factor A – ratio flux, factor B – lepo puhi/ʻala alumini puhi (quartz, gas knife earth, ʻaʻole i loli ka nui o ka frit wela).

A: potassium feldspar, albite no ka nepheline ma ka ratio o 3:1:3, pae A1 (albite / potassium feldspar / nepheline = 11/28/10), A2 (albite / potassium feldspar / nepheline = 10/25/13) , A3 (albite / potassium feldspar / nepheline = 9/22/16)

B: Aluminum puhi no ka lepo kuni e like me ka ratio o 3:5, B1 (aluminika kuni/ lepo kuni = 19/6), B2 (aluminika kuni/ lepo kuni = 16/11), B3 (aluminika kuni/ lepo kuni = 13/16)

Nui nā kumu e hoʻopōʻino ai i ka pinhole, a he mea koʻikoʻi loa ka debug a me ka hoʻopaʻa pono ʻana i ka haku mele a me ka laulā kī ʻana o ka glazed piha piha ʻole-pinhole-free. Me ka hoʻonui ʻana o ka nui o ka nepheline i loko o ke ʻano glaze, ua emi ka hapa o ka potassium feldspar a me albite, a ua hōʻike nā pinholes i kahi ʻano emi. Me ka piʻi ʻana o ka ʻāpana o ka lepo i puhi ʻia, e emi ana ka hapa o ka alumina calcined, a hōʻike nā pinholes i kahi ʻano piʻi, a me ka hope. ʻOi aku ka nui o ka lepo a me ka quartz i loko o ke ʻano, ʻoi aku ka liʻiliʻi o ka wahi pinhole-free, ʻoi aku ka liʻiliʻi o ka laulā oka hoʻohana ʻana i ke ʻano,ʻoi aku ka nui o ka ʻike o ka nepheline a me ka alumina calcined, ʻoi aku ka laulā o ke ʻano me ka ʻole o nā pinholes, a ʻoi aku ka laulā o ka hoʻohana ʻana i ke ʻano.

(1) Hoʻokaʻawale ʻia nā pinholes i ʻelua ʻano: nā pinholes haʻahaʻa haʻahaʻa a me nā pinholes kiʻekiʻe, a ʻo nā hiʻohiʻona maʻamau o nā pinholes haʻahaʻa: ʻo ka nui o nā pinholes he nui, liʻiliʻi ka nui, hele pū ʻia me ka nui o nā prickly. nā hemahema, a ʻaʻole i ʻoluʻolu a liʻiliʻi paha ke aniani o lalo; ʻO nā hiʻohiʻona maʻamau o nā pinholes wela kiʻekiʻe: he liʻiliʻi ka helu o nā pinholes, nui ka nui, ʻoi aku ka liʻiliʻi o ka wela o ka puʻu, hele pū ʻia me nā hemahema o ka lua, a ʻoi aku ke kaumaha o ka pahu hoʻokahi-lalo i ka lawe ʻana i ka inika.

(2) No nā hemahema pinhole i ka hana ʻana, pono mua e hoʻoholo inā he pinhole haʻahaʻa haʻahaʻa a i ʻole kahi pinhole wela kiʻekiʻe, e like me ke kūlana maoli, ʻoi aku ka maikaʻi o ka alumina calcined e hoʻonā i ka pinhole haʻahaʻa, a me nepheline. makemake ʻia e mālama i ka pinhole wela kiʻekiʻe.

(3) ʻO ka Quartz ma ke ʻano he mea wela kiʻekiʻe ma lalo o ka glaze formula e hoʻomaikaʻi ai i ka ʻili o ka ʻili o ke ʻano o ka mahana a me ka viscosity wela kiʻekiʻe ʻoi aku ka liʻiliʻi ma mua o ka alumina calcined, a ʻoi aku ka nui o ka quartz, ʻoi aku ka liʻiliʻi o ka wahi me ka ʻole o nā pinholes, ʻoi aku ka liʻiliʻi. laulā oka hoʻohana ʻana i ke ʻano.
