Hei te "toa ngaro" o te whakawhiti pūngao i roto i te ao ahumahi,ngā whakawhiti weratautoko puku i te whakahaere o ngā ahumahi pēnei i te matū, te hiko, me te whakarewa. Mai i te whakamatao hauhautanga ki te whakamatao miihini rōkete, kei ngā wāhi katoa tōna aroaro. Heoi, i muri i te whakawhiti wera ngāwari noa iho, ko te whiriwhiri rauemi te mea nui hei whakatau i te angitu, i te korenga rānei o ngā taputapu. I tēnei rā ka hurahia e tātou te waehere matua o ngā whakawhiti wera, ā, ka ako me pēhea te kawe mai a ngā uku silicon carbide i te auahatanga ki tēnei mara.
1. Ngā momo whakawhiti wera maha-whakamahinga
E whā ngā wāhanga matua o ngā whakawhiti wera, i runga i ō rātou āhuatanga hanganga:
1. Momo anga-ngā-ngā-ngā – he hoahoa paipa maha-paparanga e rite ana ki te tāre kōhatu, ka whakawhitia te wera e ngā pāpāho o roto, o waho hoki mā roto i te pakitara paipa, he pai mō ngā āhuatanga pēhanga teitei me te pāmahana teitei;
2. Momo pereti – he mea hanga mai i ngā pereti whakarewa kōpikopiko kua whakarārangihia ki roto i ngā awaawa maze, ka taea e te hanganga pereti angiangi te whakawhiti wera "mata ki te mata" o ngā wai wera me te matao;
3. Momo tara – ka tupu ngā parirau whakarewa ki te mata o te paipa hei whakanui ake i te horahanga o te mata, hei whakapai ake hoki i te pai o te whakawhiti wera o te hau;
4. Porowhita – Whakapikohia te awa rere kia rite ki te āhua puna hei whakaroa i te wā pa atu o te rauemi i roto i te wāhi iti.
He kēmu kei roto i ia hanganga me ngā āhuatanga ā-tinana o te rauemi: hei tauira, ahakoa he tere te kawe i te wera o ngā rauemi whakarewa tuku iho, he maha tonu ngā ngoikoretanga e whakaatuhia ana i raro i ngā āhuatanga tino kino pēnei i te waikura me te pāmahana teitei.
2, Te Huringa Rauemi: Te Pakarutanga o ngā Uku Uku Silicon Carbide
I a ngā kaihangarau e whakapai tonu ana i te hanganga o ngā whakawhiti wera, kua tere ake tēnei whanaketanga nā te putanga mai o ngā uku silicon carbide. Kei te tuhi anō tēnei rauemi uku tino kaha i hangaia i ngā ture o te ao whakawhiti wera:
1. Kaiwhakamutu Waikura
Ko te waikura matū pēnei i te waikawa kaha me te rehu tote he rite ki te "hoariri tūturu" o ngā konganuku, engari he tino teitei te ātete o ngā uku silicon carbide ki te waikura. I roto i te hanga matū, ka taea e tō rātou roanga mahi te eke ki ngā wā maha atu i te kowiri tira tuku iho, ā, ka roa ake ngā huringa tiaki taputapu.
2. Ara tere wera
Ahakoa e kiia ana he uku, he rite tonu tōna kawe wera ki te koranu konumohe. Mā te hanganga karaihe ahurei ka taea e te wera te rere pērā i runga i te huarahi, me te pai o te whakawhiti wera he maha ngā wā teitei ake i ngā uku noa, he mea tino pai mō ngā pūnaha whakahaere pāmahana tika e hiahia ana kia tere te urupare.
3. Toa pāmahana teitei
Ka taea e ia te pupuri i te pumau o te hanganga ahakoa te pāmahana teitei o te 1350 ℃, ā, he mea nui tēnei mō ngā mara motuhake pēnei i te tahunga para me te rererangi. Kua ngohengohe kē ngā rauemi whakarewa, kua rerekē hoki te āhua i roto i tēnei taiao, engari kei te kaha tonu te silicon carbide.
4. Māmā, ngāwari hoki te kawe
Ki te whakaritea ki ngā taputapu whakarewa nunui, he iti ake te mātotoru o ngā uku silicon carbide. He tino whai hua tēnei painga "māmā" mō ngā taputapu pūkoro me ngā mahi teitei, ka whakaiti tika i ngā utu kawe me te tāutanga.
3, Kei konei te heke mai: Mā ngā rauemi hou ka piki ake te whakapai ake i ngā ahumahi
I roto i te horopaki o te kore waro, kei te piki haere ngā whakaritenga mō te whai huatanga o te pūngao mō ngā taputapu ahumahi. Ehara i te mea ka whakaiti noa i te ngaronga pūngao e puta mai ana i te waikura me te tauine i ngā whakawhiti wera uku silicon carbide, engari he roa hoki te ora e whakaiti ana i te para rauemi e puta mai ana i te whakakapinga taputapu i te pūtake. I tēnei wā, kua angitu te whakamahi i tēnei hangarau i roto i ngā mara pūngao hou pērā i te whakarite silicon polycrystalline photovoltaic me te sintering rauemi pākahiko lithium, e whakaatu ana i te kaha urutau whakawhiti-rohe.
Hei kaihanga auaha e whai wāhi nui ana ki te rangahau me te whakawhanake i ngā uku silicon carbide, kei te pakaru tonu mātou i ngā arai hangarau o te hanga rauemi me te miihini tika. Mā te whakarite i ngā hua me ngā momo porosity me ngā āhuatanga mata rerekē, ka taea e tēnei 'hangarau pango' te whakatutuki i ngā hiahia motuhake o ngā momo ahumahi. Ina pāngia ngā whakawhiti wera tuku iho e ngā arai mahi, kei te arahi ngā uku silicon carbide i tētahi wā hou o te whakawhiti wera whai hua.
Ko te hītori whanaketanga o te hangarau whakawhiti wera he hītori o te auahatanga rauemi. Mai i te rino maka ki te koranu titanium, mai i te karāpiti ki te karāpiti silicon, ka puta he whakapainga iti i roto i te whai huatanga o te pūngao i ia whakawhiti rauemi. Ko te whiriwhiri i ngā uku karāpiti silicon ehara i te mea ko te whiriwhiri i ngā wāhanga taputapu pono ake anake, engari ko te whiriwhiri hoki i ngā otinga ahumahi pumau mō te heke mai.
