He kōwhiringa pai mō ngā pāpāho huri mahi teitei – ngā pirepire zirconia me ā rātou whakamahinga
I roto i te mara o te huri mākū me te horapa tino tika, kei te piki haere ngā whakaritenga mahi mō ngā rauemi huri. Ina koa i roto i ngā ahumahi pēnei i te pūngao hou, ngā hikohiko, ngā uku tino tika me ngā paninga teitei, kāore e taea e ngā rauemi huri tuku iho te whakatutuki i ngā hiahia whānui o te huri tino pai, te whakahaere parakore me te arotau i te whakapaunga pūngao. I tēnei wā, ko ngā pītiti zirconia, hei momo hou o ngā rauemi huri uku tino mahi, kei te āta haere te aro o te mākete.
He aha ngā poroporo zirconia?
He porowhita iti ngā pīrere zirconia i hangaia mai i ngā rauemi zirconia tino pumau, he kaha teitei, he pakeke teitei, he matotoru teitei, ā, he ātete pai ki te kakahu. Ko tōna rauemi matua, ko te zirconia, he pakari pai me te kore e taea te whakamahi matū, e āhei ai ngā pīrere zirconia ki te pupuri i te pumau me te roa o te mahi i roto i ngā pūnaha matotoru teitei, kutikuti teitei me te matotoru teitei.
Ko ngā momo rongonui o ngā pirepire zirconia ko:
Ngā pirepire zirconia whakapūmau Y-TZP: kua pania ki te waikura yttrium, me te matotoru me te pakeke teitei rawa, e tika ana mō te huri taumata-nano;
Ngā piripiri zirconia hiato ZTA: he mea hanga ki te alumina me te zirconia hiato, he utu-whai hua;
Ngā pirepire zirconia kua whakapūmauhia ā-wāhanga o te PSZ: he tino pakari, he pai mō te huri matotoru kaha-teitei, mō ngā tukanga huri tuatahi rānei.
Ngā painga o te mahi a ngā pirepire zirconia
Ko te take e kitea ai ngā pīrori zirconia i roto i ngā momo taputapu huri, nā ēnei āhuatanga nui e whai ake nei:
Teitei o te mātotoru (5.8~6.2 g/cm³): ka nui ake te kaha o te hurihanga, ā, ka pai ake te whai huatanga o te hurihanga;
Te pakeketanga teitei (te pakeketanga o Mohs ≥8): ehara i te mea ngāwari ki te mau, e kore e poke te rauemi huri;
Te pakari teitei: kāore e ngāwari ki te pakaru i raro i te pānga kaha, kia mau ai te pumau o te huri;
He iti te tere o te kakahu: he iti rawa te ngaronga o ngā piripiri i ia wā, ka roa ake te ora o te mahi;
He mata maeneene, he porowhita teitei: he maeneene ake te mahi, he whakaiti i te kakahu o ngā taputapu me te whakapaunga pūngao.
Whānuitanga o ngā tono
Ka taea te whakamahi whānui i ngā pīrere waikura zirconium i roto i ngā taputapu huri mākū (pēnei i ngā mira onepu whakapae, ngā mira whakaoho, ngā mira huri kete, me ētahi atu), ā, ko ō rātou whakamahinga motuhake ko:
Ngā rauemi pūngao hou: te huri i te phosphate rino lithium, ngā rauemi tuatoru, ngā irahiko kino waro-silicon, me ētahi atu;
Ngā uku mahi-teitei: e whakamahia ana mō te whakamahine paura o te waikura konumohe, te nitride silicon, te carbide silicon, me ētahi atu;
Ngā rauemi matū hiko: pērā i te paru karāhe arataki ITO, te paura uku MLCC, me ētahi atu;
Ngā waituhi paninga kounga teitei: te marara ōrite o ngā waituhi UV, ngā paninga nano, me ngā waituhi hiko;
Rongoā me te kai: e whakamahia ana mō te huri i te micronization kore-parahanga i roto i ngā rongoā koiora me ngā kai mahi.
Whakarāpopototanga
Hei rauemi huri matatau e whakakotahi ana i te kaha teitei, te parakore teitei me te pumau teitei, kei te noho hei rauemi nui ngā pirepire zirconia mō ngā momo ahumahi hei whakapai ake i te tika o te paura, hei whakau i ngā tukanga whakaputa, me te arotau i ngā hanganga utu. I te haere tonu o te whanaketanga o te hanga tika me te whakaputa matomato, ka whai wāhi nui ake ngā pirepire zirconia ki ngā tono huri mākū a meake nei.
