I te ao o te hangahanga matatau, pokepokea ai te karapitiKei te piki haere te hiranga o te hangarau. Ko te karāpiti, e mōhiotia ana mō tōna pumau wera nui, tōna ngāwari ki te miihini, me tōna ātete matū, he rauemi tino pai mō ngā pokepokea e whakamahia ana i roto i ngā tukanga hanga pāmahana teitei me te tika. I te mea kei te whanake tonu ngā ahumahi pēnei i te whakarewa, te hanga karāhe, te hikohiko, me te rererangi, kua tino piki ake te hiahia mō ngā otinga pokepokea pono me te whai hua pēnei i ngā pokepoke karāpiti.
He aha te pokepokea ai he karāpiti?
He taputapu hanga te pokepokea ai he mea hanga mai i te rauemi karāhe tino parakore. Kāore i rite ki ngā pokepokea ai he mea whakarewa tuku iho, ka taea e ngā pokepokea ai he mea whakarewa te tu atu ki ngā pāmahana tino wera me te kore e rerekē te āhua, ā, he mea tino pai mō te whakarewa me te hanga i ngā konganuku rewa, te karāhe, me ētahi atu rauemi pāmahana teitei. Ka taea te whakarite i ēnei pokepokea ai kia rite ki ngā āhuahanga uaua me ngā āheinga kikī, e tuku ana i te tino tika mō ngā mahi ahumahi.
Ngā Painga o te Mould Graphite
Ātete Wera TeiteiKa taea e ngā pokepokea graphite te tu atu i te wera nui, neke atu i te 3000°C i ngā taiao kore mahi. Nā tēnei ka tino pai mō ngā tukanga pēnei i te whakarewa tonu, te whakakikorua karāhe, me te whakahinuhinu.
Te Āheitanga Mīhini TikaHe māmā noa te mīhini i te karāpiti, ā, he tino tika, ka taea te hanga i ngā hoahoa pokepokea taipitopito me te uaua. He mea nui tēnei mō ngā ahumahi pēnei i te hikohiko me ngā haurua-ā-ira, he mea nui te tika.
Te Pūmautanga MatūHe tino ātete ngā pokepokea aira ki te waikura matū, ā, he mea tino pai mō ngā taiao tauhohe pēnei i te whakarewanga konganuku rewa me ngā tukanga whakatakotoranga kohu matū (CVD).
Whakaotinga Mata MaeneeneMā te hanganga angiangi o te karāpeti ka maeneene te mata o te pokepokea ai, ka hua ake he hua kua oti te kounga teitei, kāore he hapa.
Te Whai Hua o te UtuKi te whakaritea ki te maitai, ki ētahi atu rauemi pokepokea kounga teitei rānei, he iti ake ngā utu whakaputa me te tiaki e tukuna ana e te karāpeti, inā koa mō ngā mahi pokepokea poto, ngā mahi pokepokea ritenga rānei.
Ngā Whakamahinga Noa o te Mould Graphite
Te Makahanga Whakarewa: Whakamahia mō te whakarewatanga tonu me te whakarewatanga tika o te koura, te hiriwa, te parahi, me te konumohe.
Ahumahi KarāheHe mea nui mō te hanga i ngā wāhanga karāhe motuhake pērā i ngā arotahi, ngā ngongo, me ngā mahi toi.
Ārahi-ā-ira me te Pūngao RāWhakamahia ana i roto i te hanga i ngā anga me ngā ingota mō ngā panera rā me ngā taputapu hiko.
Te Rererangi me te TiakiHe mea tino pai mō te hanga i ngā wāhanga e pāngia ana e ngā pāmahana teitei me ngā taiao matū kino.
Te Hanga PūhikoE whakamahia ana ngā pokepokea graphite hei hanga anode me ētahi atu wāhanga mō ngā pākahiko lithium-ion.
Whakamutunga
I te whanaketanga haere o ngā hangarau hangahanga,pokepokea ai te karapitiKei te whakaatu tonu ngā otinga i tō rātou uara i runga i te tika, te roa, me te whai hua o te utu. Nā tō rātou urutau ki ngā taiao pāmahana teitei me te kaha o te matū, he mea nui rātou i roto i ngā tono ahumahi maha. Ahakoa mō te whakarewa whakarewa, te hanga karāhe, te hanga haurua-ira rānei, ka whakaratohia e ngā pokepokea karāhe te pono me te mahi e hiahiatia ana hei whakatutuki i ngā wero hanga o ēnei rā. Ko te haumi ki te hangarau pokepokea karāhe he nekehanga rautaki mō ngā ahumahi e rapu ana i te auahatanga me te hiranga.
