Kupu Whakataki: He aha te Hiranga o te Kōwhiringa o te Wēra Karāpiti i roto i ngā Whakamahinga Pāmahana-Tiketike
I roto i ngā ahumahi tukatuka wera matatau, he mea nui te mahi a ngā rauemi whakamahana ki te whakahaere i te ōritetanga o te pāmahana, te whakaiti i te whakapaunga pūngao, me te whakapai ake i te roanga o te ora o ngā taputapu.
At Pūngao VET, kua kite mātou he maha ngā kaihangarau me ngā tīma hokohoko e pāngia ana e te pātai kotahi:
Me whiriwhiri e au te Felt Ngāwari o te Graphite, te Felt Graphite Rigid rānei mō taku pūnaha whakamahana oumu?
Ahakoa nō te whānau huruhuru karāpeti ngā rauemi e rua, he rerekē ngā āhuatanga mahi i hangaia ai. Ko te kōwhiringa tika e whakawhirinaki ana ki ngā āhuatanga maha, tae atu ki:
- Te hoahoa o te oumu me te hanganga o te rohe wera
- Te pāmahana whakahaere
- Ngā whakaritenga whakamahana wera
- Ngā whakaritenga pumau ā-mīhini
- Ngā tumanakohanga mō te huringa tiaki
Ehara i te mea he whakatau rauemi noa iho te whiriwhiri i te rauemi whakamahana karāpeti tika — engari he pānga tika ki te pai o te oumu, te pumau o te tukanga, me te utu whakaputa mō te wā roa.
He aha te mea he huruhuru ngohengohe o te karapiti?
He rauemi whakamahana māmā, ngāwari hoki te muka graphite Soft Felt, he mea hanga mai i ngā matū mua o te muka waro pērā i te muka PAN, te muka rayon, te muka pitch rānei.
I te wā e hangaia ana, ka pāngia ēnei muka e ētahi tukanga matua:
- Te whakarite muka
- Te wero ngira me te hanganga huruhuru
- Te maimoatanga waro
- Te whakakāwhata pāmahana teitei
- Te horoi me te whakaoti i te mata
I muri i te whakakāwhata, ka whiwhi te rauemi i te pumau wera, te ātete matū, me te mahi pāmahana teitei.
Nā te hanganga motuhake o te muka porowhita-toru-ahu e hoatu ana ki te kiri ngohengohe o te karāhe he maha ngā painga:
- Tino iti te mātotoru
- He tino pai te kaha ki te whakamahana
- Te kaha wera iti
- Te tapahi ngāwari me te tāutanga
- He tino pai te urutau ki ngā āhuahanga oumu uaua
Ko te mātotoru o te papanga ngohengohe o te karāhe he tata ki te: 0.08–0.15 g/cm³
Nā te mea he tino pūwero tōna hanganga, he iti rawa te kawe wera o te rino karāhe ngohengohe, ā, he tino pai te pupuri wera. Ka taea e ētahi hua rino karāhe te whakatutuki i te kawe wera tata ki te 0.10–0.20 W/m·K i runga i te kounga me ngā āhuatanga pāmahana.

He aha te mea he huruhuru graphite pakari?
Ko te Rigid Graphite Felt he rauemi whakamarumaru karāpiti matatau i hangaia hei whakarato i te kaha ā-pūkaha me te pumau hanganga.
He rerekē ki te whariki ngohengohe tuku iho, ka hangaia te whariki karāpeti mā roto i ngā tukanga whakapakari tāpiri, tae atu ki:
- Whakatakotoranga paparanga
- Te hononga waro
- Te whakakī i te kapia
- Te whakawaro i te pāmahana teitei
- Te maimoatanga whakairoiro
Ko te hanganga whakamutunga e whakakotahi ana i:
- Ngā āhuatanga whakamahana muka graphite
- Whakakaha waro waro
- Ngā āhuatanga ā-ringa tautoko-whaiaro
Ki te whakatauritea ki te huruhuru karāhe ngohengohe, ka whakaratohia e te huruhuru karāhe mārō:
- Te kaha pēhi teitei ake
- He pai ake te pumau o ngā āhuatanga
- Te ātete pai ake ki te whakarerekētanga
- Te roa o te ora ratonga
Ngā awhe mātotoru noa: 0.15–0.30 g/cm³
He tino pai te whariki karāhe mārō mō ngā wāhanga oumu e hiahia ana ki te āhua pumau me te pumau hanganga mō te wā roa.
