He aha te mea he huruhuru karāpiti pakari?

I ngā tau tata nei, kua kite te ao ahumahi i te pikinga ake o te whakamahinga o ngā rauemi matatau e whakarato ana i te roa, te kaha, me te ātete wera. I roto i ēnei,te muka whatu mārōkua puta hei wāhanga nui i roto i te whānuitanga o ngā tono, mai i te whakamarumaru pāmahana teitei ki ngā tukanga hanga motuhake.

He aha te mea he huruhuru graphite?

I mua i te ruku hohonu ki te papanga karāti pakari, he mea nui kia mārama tuatahi ki tōna tūāpapa, te muka whatuKo te whatu graphite he momo rauemi waro e hangaia ana mā te huri i ngā momo muka mua, pērā i te rayon, te polyacrylonitrile rānei (PAN), hei rauemi waro mā te tukanga e mōhiotia ana ko te pyrolysis. Ko te hua he rauemi ngohengohe, ngāwari, me te mama e mau tonu ana te ātete wera me ngā āhuatanga kawe hiko teitei o te graphite.

Ahakoa e whakamahia whānuitia ana te whatu karāpiti i roto i ngā ahumahi e hiahia ana ki te whakamahana wera, pērā i roto i ngā oumu, i ngā oumu, i ngā taiwhanga rānei, nā te ngāwari o te rauemi ka whakawhāiti i tana whakamahinga i ngā āhuatanga e hiahiatia ana te pakari. Koinei te wāhi e whai wāhi ai te whatu karāpiti pakari.

He aha te mea he huruhuru karāpiti pakari?

He mea hanga ki te karāhe mārō E kiia ana hoki ko te whatu mārō karāpeti, he putanga whakarerekētanga o te whatu karāpeti, i hangaia mā roto i ngā maimoatanga me ngā tukanga tāpiri hei whakanui ake i tōna pakari me te hanganga. Kāore i rite ki tōna hoa ngāwari, ka mau tonu te āhua o te whatu karāpeti mārō i raro i te taumahatanga, ā, ka taea te tu atu i ngā āhuatanga mahi tino uaua. He maha ngā wā ka whakakiia, ka tukatukahia rānei te rauemi ki ngā mea here, ki ngā kapia rānei hei āwhina i te whakanui ake i tōna pakari, kia mau tonu ai tōna āhua totoka ahakoa ka pāngia e ngā pāmahana tino nui, e ngā kaha miihini rānei.

Ko te mea nui, e mōhiotia ana te papanga graphite pakari mō ōna āhuatangate ātete wera nui, te kawe hiko pai rawa atu, me te roa whakamiharo, he mea tino pai mō ngā ahumahi e pāngia ana e te wera me te ahotea ā-pūkaha.

Ngā Āhuatanga Matua o te Wēra Karāhe Pakari

1. Ātete ki te pāmahana teitei
   Ko tētahi o ngā āhuatanga tino whakamiharo o te whariki karāti pakari ko tōna kaha ki te tu atu i ngā pāmahana teitei me te kore e ngaro tōna hanganga. Ka taea e ia te tu atu i ngā pāmahana neke atu i te 3,000°F (1,600°C), i runga i te hanganga me te tukanga hanga motuhake. Nā tēnei ka waiho hei whiringa tino pai mō ngā tono e uru ana ki ngā āhuatanga wera nui, pērā i roto i ngā oumu, i ngā tauhohenga, i ngā pūnaha whakamahana pāmahana teitei rānei.

2. Te Arahi Wera Tino Pai
   E mōhiotia ana te karāpiti mō ōnakawe wera tino pai, koinei tētahi o ngā take e tino nui ai te uara o te whatu karāpeti mārō i roto i ngā ahumahi e hiahia ana ki te whakawhiti wera whai hua. Mā te kawe hiko teitei o te whatu karāpeti ka whakarite kia tohatohahia te wera kia ōrite, ka whakaitihia ngā pikinga wera me te ārai i ngā wāhi wera ka kino pea ki ngā taputapu me ngā rauemi tairongo.

3. Te Kaha Mīhini
   He mea hanga te muka karāpeti pakari kia tū atu ki ngā ahotea ā-ringa. Nā tōna pakari ka taea te pupuri i tōna āhua me tana mahi ahakoa ngā kaha pēnei i te pēhanga, te taumahatanga rānei. Nā tēnei āhuatanga ka tino hiahiatia i roto i ngā tono e tino hira ana te kounga o ngā rauemi, pēnei i te tātari hau me te wai, hei wāhanga hanganga rānei i roto i ngā taiao pēhanga teitei.

4. Te Āhuakore o te Matū
   He tino ātete te whatu karāpiti ki te nuinga o ngā matū, ā, he mea tino pai mō te whakamahi i roto i ngā taiao matū kaha. Kāore e waikura, e pirau rānei ina pāngia e ngā waikawa, ngā kawakore, ngā whakarewa rānei, ā, ka roa ake tōna roanga mahi me te mahi i roto i te maha o ngā tukanga ahumahi.

5. Mama
   Ahakoa tōna pakari, he mama tonu te whatu karāpeti ki te whakataurite ki ētahi atu rauemi he rite ngā āhuatanga wera me ngā āhuatanga miihini. Mā tēnei ka māmā ake te whakahaere me te tāuta, ā, ka āwhina hoki ki te whakaiti i te taumaha whānui o ngā taputapu me ngā hanganga e whakamahi ana.

Ngā tono o te Kiriata Karāhe Pakari

Nā ngā āhuatanga ahurei o te whariki karāhe pakari, he mea tino whai hua, he mea whai hua hoki i roto i ngā ahumahi maha. Ko ētahi o ngā whakamahinga matua ko:

1. Te Āraitanga Mahana-Tiketike

Ko tētahi o ngā whakamahinga tino noa o te whariki graphite pakari koārai weramō ngā oumu, ngā oumu whakarewa, me ngā tauhohenga. Nā tōna kaha ki te tu atu i ngā pāmahana teitei me te pupuri tonu i te hanganga pai, he rauemi pai mō te whakamahana i ngā taputapu nui i roto i ngā ahumahi pēnei ite mahi whakarewa, te hanga karaihe, mengā uku.

2. Ngā Pūtau Wahie

He maha ngā wā ka whakamahia te papanga graphite pakari i roto i ngāhangarau pūtau wahie, inā koa i roto i ngā pūtau wahie kiriuhi whakawhiti-porotoni (PEMFC). Nā tōna kawe hiko teitei me te pumau hanganga i raro i te wera, he mea nui ki te pupuri i te mahi a ngā pūtau, me te whakarite hoki i te tohatoha wera whai hua.

3. Ngā Parenga Wera me ngā Ārai Wera

I roto i ngā ahumahi rererangi, motuka, me ētahi atu ahumahi mahi teitei, ka whakamahia te muka karāhe pakari i roto ingā parenga weramengā ārai werahei tiaki i ngā wāhanga tairongo mai i te wera nui. Ahakoa he waka rererangi e hoki ana ki te āhuarangi o te Ao, he pūnaha whakaputa hau rānei i roto i ngā motuka mahi-teitei, ka mahi te muka karāti pakari hei ārai pono mō te ātete wera.

4. Ngā Tauhohenga Matū

Nā tōna koretake matū me tōna ātete ki te waikura, ka whakamahia te muka karāti pakari ki rotongā tauhohenga matūe mahi ana i raro i ngā āhuatanga tino kino. Ka āwhina ki te ārai me te whakau i ngā tukanga pāmahana teitei me te pupuri tonu i te pai o te whakamahinga wera.

5. Ngā tono korehau

In ngā pūnaha korehau, ka whakamahia te whatu karāti pakari hei whakapuru, hei rauemi ārai rānei. Nā tōna āhua mama me tōna ātete ki ngā pāmahana teitei ka whai hua ki te pupuri i te pono o ngā rūma korehau, kia pai ai te whakahaere wera i roto i ngā pūnaha pēnei i tengā oumu korehau or rokiroki cryogenicngā tāke.
