He aha ngā momo peera uku?

 

Ngā ingoa hua ongā peera ukuwhakaurungā peera uku zirconia, ngā peera uku silicon nitride, ngā peera uku silicon carbide, me ētahi atu. Ko ngā rauemi matua o ēnei peera ko te zirconia (ZrO2), te silicon nitride (Si3N4), te silicon carbide (SiC), me ētahi atu, he pakeke rawa, he ātete ki te kakahu, he ātete ki te pāmahana teitei, he pai rawa ngā āhuatanga miihini me te ātete ki te waikura.

 

Ina koa, ko te whakarōpūtanga ongā peera ukumā te rauemi kei roto:

Ngā peera uku zirconia:

Ka whakamahia ngā rauemi uku zirconia (ZrO2) mō ngā mowhiti amo me ngā huānga hurihuri, ko te polytetrafluoroethylene (PTFE) te nuinga o te wā e whakamahia ana mō ngā pupuri, ā, ka taea hoki te whiriwhiri i te nairon 66 (RPA66-25) kua whakapakaritia ki te muka karāhe, ngā kirihou hangarau motuhake (PEEK, PI) te maitai kore waikura rānei (AISI SUS316) me te parahi (Cu) me ētahi atu rauemi whakarewa.

Ngā peera uku silicon nitride: He mea hanga ngā mowhiti peera me ngā huānga hurihuri ki te silicon nitride (Si3N4), he tere ake, he kaha ake hoki te kawenga i ngā peera ZrO2, ā, ka taea te urutau ki ngā pāmahana teitei ake.

Ngā peera uku silicon carbide: Ka whakamahia ngā rauemi silicon carbide (SiC) mō ngā mowhiti peera me ngā huānga hurihuri, he tino pai ngā āhuatanga pēnei i te pakeke teitei, te ātete ki te kakahu, te pakari me te iti o te waku.

Hei tāpiritanga, ka whakarōpūtia ngā peera uku e ai ki te hanganga tae atu ki:

 

Ngā peera uku katoaHe mea hanga ngā mowhiti me ngā huānga hurihuri ki ngā rauemi uku, ā, he maha ngā momo whiringa e wātea ana mō te pupuri, pērā i te polytetrafluoroethylene (PTFE), te nairon 66, te polyetherimide (PEEK), te polyimide (PI), te kowiri tira, te konumohe rererangi motuhake rānei, me ētahi atu.

 

He peera uku ranu: he mea hanga te mowhiti ki ngā mea whakarewa pēnei i te maitai whāriki, te maitai kore waikura rānei, ā, ko te huānga hurihuri he pōro uku, he āhuatanga pai rawa atu pēnei i te iti o te kiato, te pakeke teitei, te ātete ki te kakahu, te pakari me te iti o te waku, ā, ka roa ake te ora mahi.

 

Ka whakarōpūtia ngā peera uku e ai ki te tono, tae atu ki:

Ngā peera tere-teitei: e whakamahia ana i roto i ngā taputapu tere-teitei, tino tika, he iti te ngāwari o te kaha, he ātete ki te pēhanga teitei, he mama te taumaha, me te whānuitanga o ngā pāmahana.

Whēra pāmahana-teitei: e whakamahia ana i roto i ngā taputapu pāmahana-teitei, ka taea te tu atu i te pāmahana teitei o te 1200°C, ā, he pai te mahi whakahinuhinu-ā-ia anō.

Ngā peera ātete-waikura: e whakamahia ana i roto i ngā taiao mahi e hiahia ana ki te aro atu ki ngā pāpāho tino kaha pērā i ngā waikawa kaha me ngā kawakore, ngā ranunga waro, te wai moana rānei.

Ārai-aukume: kore-aukume, e whakamahia ana i roto i ngā taputapu tango-aukume, ngā taputapu tika me ētahi atu taputapu, kia kore ai e pakaru ngā wāhanga o te pewa.

Ngā peera hiko kua āraihia: ngā wāhanga he ātete teitei me te pakaru pewa whai hua, e whakamahia pinepine ana i roto i ngā taputapu hiko.

Whero korehau: he pai te mahi whakahinuhinu-whaiaro, ka whakamahia i roto i te taiao korehau tino-tiketike.
