He mea hanga te pepa karāpiti mai i te karāpiti waro-rahi mā te tukatuka matū me te hurihuri whānui i te pāmahana teitei. He maeneene tōna āhua, kāore he mirumiru, he kapiti, he kita, he karawarawa, he poke me ētahi atu hapa e kitea ana. Koinei te rauemi turanga mō te hanga i ngā momo hiri karāpiti. He whānuitia te whakamahinga i roto i te hiri hihiri me te hiri tūmau o ngā mīhini, ngā paipa, ngā papu me ngā takirere i roto i te hiko, te hinu, te matū, ngā taputapu, ngā mīhini, te taimana me ētahi atu ahumahi. He rauemi hiri hou tino pai hei whakakapi i ngā hiri tuku iho pērā i te rapa, te fluoroplastics me te asbestos.
Ko ngā whakaritenga o te pepa karāpeti e whakawhirinaki ana ki tōna matotoru. He rerekē ngā whakamahinga o te pepa karāpeti, he rerekē ngā whakaritenga me ngā matotoru. Ka wehea te pepa karāpeti ki te pepa karāpeti ngāwari, te pepa karāpeti tino angiangi, te pepa karāpeti hiri, te pepa karāpeti kawe wera, te pepa karāpeti kawe, me ētahi atu. Ngā momo pepa karāpeti rerekē. Ka taea e ia te whai wāhi nui ki ngā mara ahumahi rerekē.
6 ngā āhuatanga o te pepa karāhe:
1. Ngāwari ki te tukatuka: Ka taea te tapahi pepa graphite ki ngā rahi, āhua me ngā matotoru rerekē, ā, ka taea hoki te whakarato papa papatahi tapahi-mate, ā, ko te matotoru ka taea te awhe mai i te 0.05 ki te 1.5m.
2. Ātete pāmahana teitei: ka taea e te pāmahana mōrahi o te pepa graphite te eke ki te 400℃, ā, ko te pāmahana iti rawa ka taea te iti iho i te -40℃.
3. Te kawe wera teitei: Ka taea e te kawe wera mōrahi o te pepa karāhe te eke ki te 1500W/mK, ā, ko te ātete wera he 40% te iti iho i te konumohe, ā, he 20% te iti iho i te parahi.
4. Ngāwari: Ka taea te hanga ngāwari i te pepa graphite hei paparanga mā te whakamahi i te konganuku, te paparanga ārai, te rīpene taha-rua rānei, e whakanui ake ana i te ngāwari o te hoahoa, ā, ka taea hoki te tāpiri i te piripiri ki muri.
5. Māmā me te angiangi: E 30% te māmā ake o te pepa graphite i te konumohe ōrite te rahi, ā, e 80% te māmā ake i te parahi.
6. Ngāwari ki te whakamahi: Ka taea te tāpiri maeneene i te totohu wera ki tētahi mata papatahi, piko rānei.
I te wā e penapena ana i te pepa karāhe, kia aro ki ngā mea e rua e whai ake nei:
1. Te wāhi rokiroki: He pai ake te whakatakoto i te pepa graphite ki te wāhi maroke, papatahi hoki, ā, kaua e tukua kia whiti te rā kia kore ai e pēhia. I te wā o te mahi whakaputa, ka taea e ia te whakaiti i ngā tukinga; he iti te kaha kawe hiko, nō reira, ina hiahiatia kia rongoatia, me waiho kia matara atu i te pūtake hiko, te waea hiko rānei.
2. Ārai i te pakaru: He tino ngohengohe te kakano o te pepa karāhe, ka taea te tapahi kia rite ki ngā whakaritenga, kia kore ai e pakaru i te wā e rongoa ana, kāore e pai mō te whakapiko, te piko rānei, me te whakapiko i te koki iti. He pai ngā hua pepa karāhe whānui mō te tapahi hei rau.
