Ngā tohutohu mō te tango i ngā poke mai i te paura karāhe

He maha ngā wā ka whakamahia te ipu karāpiti i roto i te hanga rauemi whakarewa me ngā rauemi haurua-ira. Hei whakatutuki i te parakore o ngā rauemi whakarewa me ngā rauemi haurua-ira, me te whakaiti i te nui o ngā poke, me paura karāpiti he nui te ihirangi waro me te iti o ngā poke. I tēnei wā, me tango ngā poke mai i te paura karāpiti i te wā e tukatukahia ana. He maha ngā kiritaki kāore e mōhio me pēhea te whakahaere i ngā poke o te paura karāpiti. I tēnei rā, ka kōrero taipitopito a Furuite Graphite Editor mō ngā tohutohu mō te tango i ngā poke o te paura karāpiti:

I te wā e hanga ana i te paura karāpiti, me tino aro turuki i te nui o ngā poke mai i ngā rauemi mata e whiriwhiria ana, me whiriwhiri i ngā rauemi mata he iti te pungarehu, ā, me ārai i te pikinga o ngā poke i te tukanga tukatuka i te paura karāpiti. Ka pirau tonu, ka mimiti haere ngā waikura o te maha o ngā huānga poke i te pāmahana tiketike, kia mau ai te parakore o te paura karāpiti e hangaia ana.

I te whakaputanga o ngā hua graphitized whānui, ka eke te pāmahana matua o te oumu ki te 2300℃, ā, ko te ihirangi paru toenga he 0.1%-0.3%. Mēnā ka whakanuia te pāmahana matua o te oumu ki te 2500-3000℃, ka tino heke te ihirangi o ngā paru toenga. I te whakaputanga o ngā hua paura graphit, ko te hinu kōke he iti te pungarehu te ihirangi e whakamahia ana hei rauemi ātete me te rauemi whakamahana.

Ahakoa ka whakanuia noa te pāmahana whakakāwhata ki te 2800℃, he uaua tonu te tango i ētahi poke. Ka whakamahia e ētahi kamupene ngā tikanga pēnei i te whakaiti i te matua o te oumu me te whakanui ake i te kiato o te iahiko hei tango i te paura kāwhata, ka whakaitihia te putanga o te paura kāwhata, ka whakanuia hoki te whakapaunga hiko. Nō reira, ina tae te pāmahana o te paura kāwhata ki te 1800℃, ka whakaurua he hau parakore, pēnei i te chlorine, te freon me ētahi atu chlorophosphates me te fluorides, ā, ka tāpirihia tonutia mō ētahi haora i muri i te korenga o te hiko. Hei ārai i ngā poke mimiti kei horapa ki roto i te oumu i te taha ke, ā, hei pana i te hau parakore e toe ana mai i ngā pūwero o te paura kāwhata mā te whakauru i ētahi hauota.
