Ngā āhuatanga o ngā peera karāhe

Ngā āhuatanga o ngā peera karāhe

1. He pai te pumau matū
He rauemi pumau matū te karāpiti, ā, kāore tōna pumau matū i te iti iho i te pumau o ngā konganuku utu nui. Ko tōna wairewatanga i roto i te hiriwa rewa he 0.001% – 0.002% noa iho.KarāpitiKāore e wairewa i roto i ngā whakarewa waro, kore-waro rānei. Kāore e waikura, ā, e wairewa ana i roto i te nuinga o ngā waikawa, ngā kawa me ngā tote.
2. Te ātete pāmahana teitei o te peera graphite
Mā roto i ngā whakamātautau, ka taea e te pāmahana ratonga o ngā peera waro whānui te eke ki te 350 ℃; ko te peera karāhe whakarewa he 350 ℃ hoki; ka taea e te peera karāhe hikohiko te eke ki te 450-500 ℃ (i raro i te kawenga māmā), ka noho tonu ōna āhuatanga ā-tinana me te ā-pūkaha, ā, ka taea e tōna pāmahana ratonga te eke ki te 1000 ℃ i raro i te korehau, i te hau tiaki rānei.
3. He pai te mahi whakahinuhinu-whaiaro
Te peera o te karāpitiHe pai te mahi whakahinuhinu-ā-roto mō ngā take e rua. Ko tētahi o ngā take he mea whakarite ngā ngota waro i roto i te whatunga karāpeti ki runga i ia papa i roto i te āhua hexagonal ōrite. He tata te tawhiti i waenga i ngā ngota, arā, 0.142 nm, ko te tawhiti i waenga i ngā papa he 0.335 nm, ā, he rite tonu te ahunga o te tawhiti. Ka tāruatia e te papa tuatoru te tūranga o te papa tuatahi, ka tāruatia e te papa tuawhā te tūranga o te papa tuarua, ā, pērā tonu. I roto i ia papa, he tino kaha te kaha here i waenga i ngā ngota waro, he nui te tawhiti i waenga i ngā papa, ā, he tino ngoikore te kaha van der Waals i waenga i a rātou, nō reira he ngāwari te wehe me te paheke i waenga i ngā paparanga, koinei te take matua he āhuatanga whakahinuhinu-ā-roto ngā rauemi karāpeti.
Ko te take tuarua, he kaha te piri o ngā rauemi karāpeti ki te nuinga o ngā rauemi whakarewa, nō reira ka taea e te karāpeti kua tangohia te kiri te piri ngāwari ki te mata whakarewa ina huri ana me te whakarewa, ka hanga he paparanga okiriata karāhe, ka huri hei waku i waenga i te karāpeti me te karāpeti, ā, ka tino whakaiti i te tauwehenga kakahu me te waku. Koinei hoki tētahi o ngā take he pai rawa atu te mahi whakahinuhinu-ake me te mahi ārai-waku o ngā peera karāpeti waro.
4. Ētahi atu āhuatanga o te peera karāhe
Ki te whakataurite ki ētahi atu peera,ngā peera karāhehe nui hoki te kawe wera, he iti te tauwehenga o te whakawhānui raina, he tere te whakamatao me te ātete wera me ētahi atu.
