He aha te karāhe whakakikoruatia ki te hiraka?
Ko te karāhe hiraka-whakamārama, e kiia ana hoki ko te tānga hiraka, ko te karāhe tā mata rānei, he mea hanga ritenga mā te whakawhiti i tētahi ahua mata hiraka ki te karāhe, kātahi ka tukatukahia mā roto i tētahi oumu whakamahana whakapae. Ka tāia mata ia mata ki te tauira e hiahiatia ana me te tae o te paraihe enamel uku. Ka taea te tā i te paraihe uku ki runga i te papa karāhe i roto i tētahi o ngā tauira paerewa e toru – ngā ira, ngā rārangi, ngā kōhao – i roto rānei i tētahi tono kapi katoa. Hei tāpiri, ka taea te tārua ngāwari i ngā tauira ritenga ki runga i te karāhe. I runga i te tauira me te tae, ka taea te hanga i te paraihe karāhe kia mārama, kia mārama, kia kore e mārama.
Ko te karāhe whakapakari matū he momo karāhe kua piki ake te kaha nā te tukanga matū i muri i te hanga. Ina pakaru, ka pakaru tonu hei maramara roa, koi, rite tonu ki te karāhe pōtae. Nā reira, kāore e kiia he karāhe haumaru, ā, me pania ki te whakakikorua mēnā e hiahiatia ana he karāhe haumaru. Heoi, ko te karāhe whakapakari matū he ono ki te waru ngā wā te kaha ake i te karāhe pōtae.
Ka whakapakarihia te karāhe mā te whakamahi i tētahi tukanga whakaoti mata. Ka rumakina te karāhe ki roto i tētahi kaukau kei roto he tote pāhare pākawa (te nuinga he pāhare pākawa hauota) i te 300 °C (572 °F). Mā tēnei ka whakakapia ngā katote konutai i roto i te mata karāhe e ngā katote pāhare pākawa mai i te wai kaukau.
He nui ake ēnei iona pāhare pākawa i ngā iona konutai, nō reira ka piri ki roto i ngā āputa i mahue i ngā iona konutai iti ake ina heke ki te otinga pāhare pākawa nitaita. Mā tēnei whakakapinga o ngā iona ka noho te mata o te karāhe i roto i te āhua pēhitanga me te uho i roto i te āhua whakaea te taumahatanga. Ka eke pea te pēhitanga o te mata o te karāhe kua whakakahangia e te matū ki te 690 MPa.

He aha te karāhe haumaru?
Ko te karāhe whakapakeke, he momo karāhe haumaru rānei e tukatukahia ana mā roto i ngā maimoatanga wera, matū rānei e whakahaeretia ana hei whakanui ake i te kaha o te karāhe.
tōna kaha ki te whakataurite ki te karāhe noa.
Mā te whakamahana ka pēhia ngā mata o waho, ka kumekume hoki ngā mata o roto.
Ngā painga o te karāhe whakamaroke
1. Haumarutanga: Ina pakaru te karāhe i waho, ka huri ngā para hei kongakonga iti, ā, ka uaua ki te whara i te tangata.
2. Kaha rawa: ko te kaha pānga o te karāhe whakamaroke he rite te matotoru ki te karāhe noa, e 3 ki te 5 ngā wā nui ake i te karāhe noa, ā, ko te kaha piko he 3-5 ngā wā.
3. Te pumau o te wera: He pai te pumau o te karāhe whakamaroke, ka taea te tu atu i te pāmahana neke atu i te 3 ngā wā i te karāhe noa, ka taea hoki te tu atu i ngā huringa pāmahana 200 °C.
