ʻO kahi koho kūpono no nā media wili kiʻekiʻe - zirconia beads a me kā lākou noi
Ma ke kahua o ka wili pulu kiʻekiʻe a me ka hoʻopuehu, ke hoʻonui nei nā koi hana no ka wili ʻana i ka media. ʻOi aku ma nā ʻoihana e like me ka ikehu hou, nā uila, nā seramika pololei a me nā uhi kiʻekiʻe, ʻaʻole hiki i ka media wili kuʻuna ke hoʻokō i nā pono piha o ka wili ultra-fine, ka hoʻomaʻemaʻe ʻana a me ka hoʻohana ʻana i ka ikehu. I kēia manawa, ʻo ka zirconia beads, he ʻano hou o ka media grinding ceramic kiʻekiʻe, ke lilo mālie nei i kumu o ka nānā ʻana i ka mākeke.
He aha nā lei zirconia?
ʻO nā peʻa Zirconia he mau pōʻai liʻiliʻi i hoʻopaʻa ʻia mai nā mea zirconia paʻa me ka ikaika kiʻekiʻe, kiʻekiʻe paʻakikī, kiʻekiʻe kiʻekiʻe a me ke kūpaʻa maikaʻi loa. ʻO kāna mea waiwai nui, ʻo zirconia, he paʻakikī maikaʻi a me ka inertness kemika, e hiki ai i ka zirconia beads ke mālama i ka paʻa maikaʻi a me ke ola lawelawe i ka nui o ka ikehu kiʻekiʻe, kiʻekiʻe shear a me nā ʻōnaehana viscosity kiʻekiʻe.
ʻO nā ʻano maʻamau o nā peʻa zirconia penei:
Y-TZP stabilized zirconia beads: doped me ka yttrium oxide, me ka kiʻekiʻe kiʻekiʻe a me ka paakiki, kūpono no ka nano-level wili;
ʻO ZTA composite zirconia beads: i hanaʻia me ka alumina a me ka zirconia composite, ke kumu kūʻai;
ʻO nā lei zirconia i hoʻopaʻa hapa ʻia ʻo PSZ: ʻo ka ʻoʻoleʻa maikaʻi loa, kūpono no ka wili koʻikoʻi ikaika a i ʻole nā kaʻina wili mua.
ʻO nā pōmaikaʻi o ka hana ʻana o nā lei zirconia
ʻO ke kumu o ka hiki ʻana o nā peʻa zirconia ke kū i waena o nā media wili he nui ma muli o kā lākou mau hiʻohiʻona koʻikoʻi:
Kiʻekiʻe kiʻekiʻe (5.8 ~ 6.2 g/cm³): lawe mai i ka ikehu kinetic wili kiʻekiʻe a hoʻomaikaʻi i ka pono wili;
ʻO ka paʻakikī kiʻekiʻe (Mohs hardness ≥8): ʻaʻole maʻalahi ke ʻaʻahu, ʻaʻole ia e hoʻohaumia i ka mea wili;
ʻO ka paʻakikī kiʻekiʻe: ʻaʻole maʻalahi e uhaʻi ma lalo o ka hopena kiʻekiʻe, e hōʻoia ana i ka paʻa ʻana o ka wili;
Haʻahaʻa haʻahaʻa haʻahaʻa: liʻiliʻi liʻiliʻi o ka pohō o nā pahu i kēlā me kēia manawa, hoʻonui i ke ola lawelawe;
ʻO ka ʻili maʻemaʻe a me ka sphericity kiʻekiʻe: ʻoi aku ka maʻalahi o ka hana ʻana, e hōʻemi ana i ka hoʻohana ʻana i nā mea hana a me ka hoʻohana ʻana i ka ikehu.
Laulā o nā noi
Hiki ke hoʻohana nui ʻia nā peʻa Zirconium oxide i nā mea wili pulu ʻokoʻa (e like me nā wili one horizontal, stirred mill, basket grinders, etc.), a me kā lākou mau noi kikoʻī akā ʻaʻole i kaupalena ʻia i:
Nā mea ikehu hou: ka wili ʻana o ka lithium iron phosphate, nā mea ternary, nā electrodes maikaʻi ʻole silicon-carbon, etc.;
ʻO nā seramika hana kiʻekiʻe: hoʻohana ʻia no ka hoʻomaʻemaʻe pauka o ka alumini oxide, silicon nitride, silicon carbide, etc.;
ʻO nā mea kemika uila: e like me ITO conductive glass slurry, MLCC ceramic powder, etc.;
Kiʻekiʻe-hopena uhi inika: homogeneous dispersion o UV inika, nano coatings, a me ka uila inika;
ʻO ka lāʻau lapaʻau a me ka meaʻai: hoʻohana ʻia no ka micronization wili ʻole i ka pollution-free micronization i nā biopharmaceuticals a me nā meaʻai hana.
Hōʻuluʻulu manaʻo
Ma ke ʻano he ʻano hana wili holomua e hui pū ai i ka ikaika kiʻekiʻe, ka maʻemaʻe kiʻekiʻe a me ke kūpaʻa kiʻekiʻe, ua lilo ka zirconia beads i mea waiwai no nā ʻoihana like ʻole e hoʻomaikaʻi i ka pololei o ka pauka, hoʻopaʻa i nā kaʻina hana, a hoʻopaʻa i nā hale kumukūʻai. Me ka hoʻomau mau ʻana o ka hana pololei a me ka hana ʻōmaʻomaʻo, e pāʻani ka zirconia beads i kahi kuleana nui i nā noi wili pulu e hiki mai ana.
