He aha ngā momo rerekē o ngā peera uku?

 

Ngā peera ukukei roto ko ngā peera uku zirconia, ngā peera uku silicon nitride, me ngā peera uku silicon carbide. Ko ngā rauemi matua e whakamahia ana i roto i ēnei peera ko te zirconia (ZrO2), te silicon nitride (Si3N4), me te silicon carbide (SiC), he pakeke teitei, he ātete ki te kakahu, he ātete ki te pāmahana teitei, he āhuatanga miihini pai rawa atu, me te ātete ki te waikura.

 

Ina koa, ka taea te whakarōpū i ngā peera uku e ai ki ngā rauemi e whai ake nei:

 

Waikura ZirconiumNgā Peera UkuHe mea hanga ngā mowhiti whāriki me ngā huānga hurihuri ki te uku zirconia (ZrO2). Ko te nuinga o te wā, he mea hanga te whare herehere ki te polytetrafluoroethylene (PTFE), engari ka taea hoki te whakamahi i ngā rauemi motuhake pēnei i te nairona 66 (RPA66-25) kua whakapakarihia ki te muka karāhe, ngā kirihou hangarau motuhake (PEEK, PI), te maitai kore waikura (AISI SUS316), me te parahi (Cu).

 

Nitride HirakaNgā Peera UkuHe mea hanga ngā mowhiti whāriki me ngā huānga hurihuri ki te silicon nitride (Si3N4). Ki te whakatauritea ki ngā whāriki ZrO2, he tere ake, he kaha ake hoki ō rātou kawenga, ā, ka taea hoki e rātou te tu atu i ngā pāmahana teitei ake.

 

Ngā peera uku silicon carbide: He mea hanga ngā mowhiti peera me ngā huānga hurihuri ki te silicon carbide (SiC), 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 taea te whakarōpū i ngā peera uku mā te hanganga penei:

 

Ngā peera uku katoaHe mea hanga ngā mowhiti me ngā huānga hurihuri ki ngā rauemi uku. He maha ngā kōwhiringa o te whare herehere, pērā i te polytetrafluoroethylene (PTFE), te nairona 66, te polyetherimide (PEEK), te polyimide (PI), te maitai kore waikura, te konumohe rererangi motuhake rānei.

 

Ngā peera uku ranu: He mea hanga ngā mowhiti ki te maitai peera, ki te maitai kore waikura rānei, ko ngā wāhanga hurihuri he pōro uku. He tino pai ngā āhuatanga 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 o te mahi.

 

Ngā peera ukuka taea te whakarōpū mā te tono penei:

 

Ngā peera tere-teitei: E whakamahia ana i roto i ngā taputapu tere-teitei, tino tika. He iti te ngāwari i raro i te ahotea, he kaha pēhi teitei, he mama, ā, he whānui te awhe manawanui pāmahana.

 

Ngā peera pāmahana-teitei: Ka whakamahia i roto i ngā taputapu pāmahana-teitei, ka taea te tu atu i ngā pāmahana tae atu ki te 1200℃, ā, he pai hoki ngā āhuatanga whakahinuhinu-ake.

 

Ngā peera ātete-waikura: Ka whakamahia i roto i ngā taiao uaua e hiahia ana kia ātete ki ngā waikawa kaha, ki ngā kawakore, ki ngā ranunga waro, ki te wai moana rānei.

 

Ngā peera ārai-aukume: Kore-aukume, e whakamahia ana i roto i ngā taputapu tango-aukume, ngā taputapu tika, me ētahi atu, e ārai pai ana i te āwhata me te pakaru o ngā wāhanga.

 

Ngā peera hiko kua āraihia: He ātete teitei, he ārai pai i te pupuhi me te pakaru o ngā wāhanga, e whakamahia pinepine ana i roto i ngā taputapu hiko.

 

Ngā peera korehau: He pai ngā āhuatanga whakahinuhinu-ake, e whakamahia ana i roto i ngā taiao korehau tino tiketike.
