Zirconia Powder Applications
Matou te tuʻuina atu le paʻu zirconia maualuga, lea e mafai ona faʻaaogaina i le tele o taimi, e pei o mea cathode o le lithium battery, fausaga TZP, nifo, le pito i tua o le telefoni feaveaʻi, zirconia gem, faatasi ai ma i latou:
Fa'aaogaina o mea lelei:
O le paʻu o le zirconia e tuʻuina mai e matou o loʻo i ai uiga o le lapoʻa lelei, faʻasoa faʻameamea tutusa, leai se faʻaputuga faigata, ma le sphericity lelei.O le tu'uina i totonu o mea cathode o le maa lithium e mafai ona fa'aleleia ai le ta'amilosaga a le maa ma le fa'atinoga o le fa'atinoga.I le faʻaaogaina o lona faʻauluuluga, e mafai ona faʻaogaina le paʻu zirconia mama maualuga mo le gaosiga o le eletise i totonu o le maa malosi maualuga.Zirconia paʻu (99.99%) e mafai ona faʻaaogaina e fai ma anode mea mo maa lithium, e pei o le nickel cobalt lithium manganate (NiCoMn) O2), lithium cobaltite (LiCoO2), lithium manganate (LiMn2O4).
Mo sui fa'avae:
TZP, tetragonal zirconia polycrystalline ceramics.Pe a pulea le aofaiga o le stabilizer i se aofaiga talafeagai, t-ZrO2 e mafai ona teuina i se tulaga metastable i le vevela potu.I lalo o le gaioiga o le malosi i fafo, e mafai ona suia le vaega t-ZrO2, faʻamalosia le suiga ole vaega ole ZrO2 tino, ma faʻaleleia le laina gau a le ceramic.O le TZP o loʻo i ai ni mea faʻainisinia sili ona lelei e pei o le maualuga o le malosi, maualuga le malosi, ma le maualuga o le ofuina.E mafai ona faʻaaogaina e fai ai vaega faʻavae e faʻafefe afi ma maualuga-vevela.
Mo nifo porselana:
Zirconia e maualuga le malosi, lelei le biocompatibility, leai se faʻaosofia i le gingiva, ma e leai se faʻafitauli faʻafefe, o lea e fetaui lelei mo le faʻaogaina tautala.O le mea lea, e masani ona faʻaaogaina le paʻu zirconia e fai ai nifo ceramic zirconia.Zirconia all-ceramic nifo e faia i le mamanu fesoasoani i komepiuta, su'esu'e leisa, ona pulea lea e se polokalame komepiuta.E i ai uiga o foliga lelei translucent, maualuga-density, ma le malosi, atoatoa latalata pito, leai gingivitis, leai se faalavelave i X-ray, ma isi.E mafai ona maua ni a'afiaga fa'aleleia umi ile falema'i.
Fa'aaoga e fai ai le pito i tua o le telefoni fe'avea'i:
I le vaitau o le 5G, e tatau ona 1-100 taimi o le 4G le saoasaoa o le faʻasalalau.O feso'ota'iga 5G e fa'aogaina ai le alaleo e sili atu nai lo le 3GHz, ma o lona galu-millimita-galu umi e pu'upu'u.Pe a faatusatusa i le u'amea i tua, e leai se fa'alavelave i le fa'ailoga o le telefoni fe'avea'i ma e le mafaatusalia, e sili atu le fa'atinoga o isi mea.I totonu o mea uma sima, o le zirconia ceramic o loʻo i ai le lelei o le malosi maualuga, maualuga maualuga, faʻamaʻi ma le alkali, faʻamaʻi faʻamaʻi, ma le maualuga o vailaʻau.I le taimi lava e tasi, o loʻo i ai uiga o le teteʻe atu, leai se faʻailoga e puipuia ai, sili ona lelei le faʻaogaina o le vevela, ma foliga lelei.O le mea lea, o le zirconia ua avea ma ituaiga fou o mea telefoni feaveaʻi pe a uma le palasitika, uʻamea, ma tioata.I le taimi nei, o le zirconia ceramic application i telefoni feʻaveaʻi e masani lava ona aofia ai se pito i tua ma se faʻailoga faʻailoga tamatamailima ufiufi ipu.
Faʻaaogaina e fai ai le zirconia maa:
O le gaosiga o zirconia gemstones mai le paʻu o le zirconia o se vaega taua o le faʻaogaina loloto ma le faʻaogaina o le zirconia.O le synthetic cubic zirconia o se tioata malō, e leai se lanu, ma e leai se pona.Ona o lona tau maualalo, umi, ma foliga tutusa i taimane, cubic zirconia gemstones ua sili ona taua e suitulaga i taimane talu mai le 1976.
