Koho kūpono no nā pāpaho wili hana kiʻekiʻe - nā momi zirconia a me kā lākou noi
Ma ke kahua o ka wili pulu kiʻekiʻe a me ka hoʻopuehu ʻana, ke piʻi nei nā koi hana no ka wili ʻana i nā mea hana. ʻOi loa aku i nā ʻoihana e like me ka ikehu hou, nā mea uila, nā keramika pololei a me nā uhi kiʻekiʻe, ʻaʻole hiki i nā mea hana wili kuʻuna ke hoʻokō hou i nā pono piha o ka wili maikaʻi loa, ka kaohi maʻemaʻe a me ka hoʻonui ʻana i ka hoʻohana ʻana i ka ikehu. I kēia manawa, ʻo nā momi zirconia, ma ke ʻano he ʻano hou o nā mea hana wili keramika kiʻekiʻe, ke lilo mālie nei i mea nui o ka nānā ʻana o ka mākeke.
He aha nā momi zirconia?
ʻO nā momi Zirconia he mau poepoe liʻiliʻi i hoʻopili ʻia mai nā mea zirconia paʻa loa me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka nui o ka mānoanoa a me ke kūpaʻa ʻana i ka ʻaʻahu maikaʻi loa. ʻO kāna mea maka nui, ʻo zirconia, he paʻakikī maikaʻi a me ka inertness kemika, e hiki ai i nā momi zirconia ke mālama i ke kūpaʻa maikaʻi loa a me ke ola lawelawe i ka nui o ka ikehu, ka ʻoki kiʻekiʻe a me nā ʻōnaehana viscosity kiʻekiʻe.
ʻO nā ʻano maʻamau o nā momi zirconia e komo pū ana:
ʻO nā momi zirconia paʻa ʻo Y-TZP: i hoʻohui ʻia me ka yttrium oxide, me ka nui a me ka paʻakikī kiʻekiʻe loa, kūpono no ka wili ʻana i ka pae nano;
ZTA composite zirconia beads: hana ʻia me ka alumina a me ka zirconia composite, kūpono ke kumukūʻai;
Nā momi zirconia i hoʻopaʻa hapa ʻia e PSZ: paʻakikī maikaʻi loa, kūpono no ka wili ʻana i ka ikehu kiʻekiʻe a i ʻole nā kaʻina wili mua.
Nā pōmaikaʻi hana o nā momi zirconia
ʻO ke kumu e kū ai nā momi zirconia i waena o nā mea wili he nui ma muli o ko lākou mau ʻano koʻikoʻi:
Kiʻekiʻe ka nui (5.8~6.2 g/cm³): lawe mai i ka ikehu kinetic wili kiʻekiʻe a hoʻomaikaʻi i ka pono o ka wili ʻana;
Paʻakikī kiʻekiʻe (paʻakikī Mohs ≥8): ʻaʻole maʻalahi ke komo, ʻaʻole ia e hoʻohaumia i ka mea wili;
Paʻakikī kiʻekiʻe: ʻaʻole maʻalahi ka uhaki ʻana ma lalo o ka hopena kiʻekiʻe, e hōʻoiaʻiʻo ana i ke kūpaʻa wili;
ʻO ka helu komo haʻahaʻa: nalowale liʻiliʻi loa o nā momi i kēlā me kēia manawa, e hoʻolōʻihi ana i ke ola lawelawe;
ʻO ka ʻili laumania a me ke ʻano sphericity kiʻekiʻe: hana ʻoi aku ka laumania, e hōʻemi ana i ka ʻaʻahu o nā lako a me ka hoʻohana ʻana i ka ikehu.
Nui nā noi
Hiki ke hoʻohana nui ʻia nā momi oxide Zirconium i nā lako wili pulu like ʻole (e like me nā wili one pālahalaha, nā wili i hoʻoulu ʻia, nā wili hīnaʻi, a me nā mea ʻē aʻe), a ʻo kā lākou mau noi kikoʻī e komo pū me kēia mau mea:
Nā mea ikehu hou: ka wili ʻana o ka lithium hao phosphate, nā mea ternary, nā electrodes silicon-carbon maikaʻi ʻole, a pēlā aku;
Nā keramika hana kiʻekiʻe: hoʻohana ʻia no ka hoʻomaʻemaʻe pauka o ka alumini oxide, silicon nitride, silicon carbide, a pēlā aku;
Nā mea kemika uila: e like me ka slurry aniani alakaʻi ITO, ka pauka seramika MLCC, a pēlā aku;
Nā ʻīnika uhi kiʻekiʻe: ka hoʻopuehu like ʻana o nā ʻīnika UV, nā uhi nano, a me nā ʻīnika uila;
ʻO ka lāʻau lapaʻau a me ka meaʻai: hoʻohana ʻia no ka wili ʻana i ka micronization ʻole haumia i nā biopharmaceuticals a me nā meaʻai hana.
Hōʻuluʻulu manaʻo
Ma ke ʻano he mea wili holomua e hoʻohui i ka ikaika kiʻekiʻe, ka maʻemaʻe kiʻekiʻe a me ke kūpaʻa kiʻekiʻe, ke lilo nei nā momi zirconia i mea nui no nā ʻoihana like ʻole e hoʻomaikaʻi i ka pololei o ka pauka, hoʻopaʻa i nā kaʻina hana, a hoʻonui i nā ʻano kumukūʻai. Me ka holomua mau o ka hana pololei a me ka hana ʻōmaʻomaʻo, e pāʻani nā momi zirconia i kahi kuleana koʻikoʻi i nā noi wili pulu i ka wā e hiki mai ana.
