Te ahunga whanaketanga ā muri ake nei me te whanaketanga hangarau o te paura iti o te korundum ma
I a ia e hikoi ana ki roto i tētahi awheawhe hanga tino tika i Shenzhen, i āwangawanga a Li Gong mō te karu hiko – he puranga o ngā papa uku i whakamahia mō ngā karaihe mīhini tuhi whakaahua he karawarawa taumata-nano kei runga i ō rātou mata. Whai muri i te whakakapinga o te mea hou kua whakawhanakehia he iti-konutaipaura moroiti kōrunuma māI te wai whakakanapa me te kaihanga, ka ngaro whakamiharo ngā karawarawa. "He rite tēnei paura ki ōna kanohi, ā, ka 'ngau' noa i ngā puku, kāore e whara te papa!" Kāore i taea e ia te ārai i te papaki i tōna mahunga me te miharo. E whakaata ana tēnei tirohanga i te panonitanga hangarau e pā ana ki te umanga paura iti korundum mā. Ko ngā "niho ahumahi" puehu i mua kei te huri hei "ngā niho nano" mō te hanga kounga teitei.
1. Ngā āwangawanga o te umanga o nāianei: Ko te umanga paura moroiti kei te huarahi whakawhiti o te panonitanga
Te āhua nei kei te tino puāwai te mākete paura moroiti korundum mā o te ao – ko Haina, te kaihanga nui rawa atu, e neke atu ana i te 60% o te hanga o te ao, ā, ka neke atu te rahi o te mākete i te 10 piriona i te tau 2022227. Engari ina tomo koe ki te wāhi wheketere i Gongyi, Henan, ka ruru ngā mahunga o ngā rangatira i te nui o ngā taonga: "Kāore e taea te hoko i ngā taonga iti te utu, ā, kāore e taea te hanga i ngā taonga utu nui." E whakaatu ana tēnei i ngā raruraru nui e rua i roto i te umanga:
Te kaha nui rawa o te mutunga iti: Kua tino ōrite ngā hua paura moroiti tuku iho, kua mau i roto i te awhiowhio pakanga utu, ā, kua heke te tawhē hua ki raro iho i te 10%.
Kāore i te rawaka te tuku kounga teitei:Paura moroiti taumata-haurua-aratakikei te whakawhirinaki tonu ki ngā kawemai, ā, ko te hua parakore 99.99% a tētahi kaihanga o te ao ka hokona i te utu tae atu ki te 500,000 yuan ia tana, arā, e 8 ngā wā teitei ake i ngā hua o roto.
Ko te mea nui ake, ko te kaha haere o te kanga tiaki taiao. I te tau kua hipa, i whiua he 1.8 miriona ki tētahi wheketere tawhito i Zibo, Shandong mō te hipa i te paerewa o te whakawera i te hau putanga o te oumu. Ātaata pouri ana te rangatira: "Ka pau ngā hua i ngā utu tiaki taiao, engari ki te kore koe e tāuta i ngā taputapu hou, me kati koe!" 8 I te tīmatanga o te tono a ngā kiritaki o te heke mai i ngā tiwhikete tapuwae waro, kua tae te wā o te whakaputanga nui ki te tatau whakamuri.
2. Ngā putanga hangarau: E whā ngā pakanga kei te haere tonu
(1) Te whakarite i te nanoscale: te pakanga ki te huri i te "paura moroiti" hei "paura pai"
Te whakataetae rahi matūriki: Kua tutuki i ngā kamupene matua te whakaputanga papatipu o ngā paura moroiti i raro i te 200 nanometer, he kotahi noa te porowhita nui ake i te coronavirus hou (tata ki te 100 nanometer).
Te whanaketanga hou o te hangarau marara: Mā te tukanga whakarōpūtanga waipēhi patent a te Kamupene Hanshou Jincheng e whakaoti te raruraru o te kohikohinga matūriki mā te tāpiri i tētahi mea marara hiato, ka pēhia te marara rahi matūriki o te puranga hua kotahi mai i te ±30% ki roto i te ±5%.
Te whakahaere i te āhua o te tinana: Mā te whakaporowhita ka taea te whakakapi i te waku hurihuri paura moroiti i te waku reti, ā, ka heke te tere pakaru oro mā te 70%.6. I whakaahuahia e tētahi miihini nō tētahi kamupene Hapanihi penei: "He rite ki te whakakapi i te kirikiri ki ngā pīrori karāhe, ā, ka heke noa te tūponotanga o ngā karawarawa."
(2) Te hurihanga iti o te konutai: Ko te parakore te mea e whakatau ana i te uara
E kino ana te umanga haurua-ira ki ngā iona konutai – ka taea e te parahanga konutai te rahi o te pata tote te whakangaro i te wafer katoa. Kua noho te paura kōrunuma ma iti-konutai (te ihirangi Na2O ≤ 0.02%) hei taonga rongonui:
Whakapai ake i te hangarau rewa āwhata: Kua whakamahia te rewa tiaki hau korekore, ā, kua piki ake te tere whakarewa konutai mā te 40%
Mahere whakakapi rauemi mata: Ka whakamahia te kaolin hei whakakapi i te bauxite, ā, ka heke noa te ihirangi konutai neke atu i te 60%
Ahakoa e toru ngā wā teitei ake te utu o tēnei momo hua i tō te paura noa, he iti noa iho. Ko te raina iti-konutai kua hangaia i roto i tētahi wheketere i Jiangxi, kei te haere tonu ngā ota tae noa ki te tau 2026.
(3)Te hanga matomato: te whakaaro nui i akiakihia e te tiaki taiao
Te hangarua rauemi mata: Ka taea e te hangarau hangarua wira huri para te whakanui ake i te tere hangarua o te paura para ki te 85%, ka whakaiti i te utu mā te 4,000 yuan ia tana
Huringa tukanga: Ka whakakapia katoatia te tikanga mākū e te tukanga hanga paura maroke, ā, ka whakaitihia te tukunga waipara ki te kore. I whakauruhia e ngā umanga Henan he pūnaha whakaora wera para, ā, i heke te whakapaunga pūngao mā te 35%.
Te whakarerekētanga o te para totoka: I hurihia e tētahi wheketere i Liaocheng, Porowini o Shandong te para para hei rauemi hanga whare ātete ahi, ā, e rua miriona yuan te moni whiwhi i ia tau. I kata te rangatira: "I mua, ko te tiaki taiao he huarahi hei hoko haumaru, engari ināianei he huarahi hou hei whiwhi moni."
(4) Te whakaputa atamai: te peke tika e whakahaerehia ana e te raraunga
I roto i te awheawhe matihiko o Zhengzhou Xinli, e whakaatu ana te mata nui i te pihi tohatoha rahi matūriki o te paura iti i te wā tūturu. "Ka taea e te pūnaha tātaritanga AI te whakarerekē i ngā tawhā rere o te hau, kia piki ake ai te reiti tohu hua mai i te 82% ki te 98%." I tohu te kaiwhakahaere hangarau ki ngā taputapu e rere ana, ā, i mea 6. Mā te aroturuki ipurangi o te tātari rahi matūriki taiaho me te raupapa ako mīhini ka taea te whakatutuki i te urupare taumata tuarua mō ngā huringa kounga, ka poroporoaki katoa ki te aratau "muri-tirotiro" tuku iho.
3. Te papa pakanga o muri mai: he panonitanga ataahua mai i ngā wira huri ki ngā maramara
Ko te "e whai ake nei"ara koura"Kei te puare ake te paura iti o te kōrunuma mā:
Tākai hiko-ā-ira: e whakamahia ana mō te whakangawari me te whakakanapa i te anga silicon, me te tere tipu ā-tau o te tono ā-ao neke atu i te 25%
Mara pūngao hou: hei rauemi paninga wehewehe pākahiko lithium, hei whakapai ake i te ātete wera me te kawe katote
Hauora-koiora: Te whakakanapa-nano i ngā whakahoutanga uku niho, me te whakaritenga tika o te 0.1 maikorona
Ko te whanaketanga o te paura iti o te korundum mā he tirohanga poto noa iho o te whakapai ake i te hanga o Haina. I te wā i whakamahia ai e te wheketere tawhito i Zibo te tānga 3D hei hanga anō i te papa rere o te oumu whakawera, ā, i te wā i whakatipuhia ai e te tīma o te Chinese Academy of Sciences ngā porowhita iti o te alumina tioata kotahi i roto i te taiwhanga, kāore i whakatauhia te hua o tēnei "pakanga maikoromita" e te kaha whakaputa o nāianei, engari e te tangata ka taea te tautuhi i te tūāpapa o te hanga ā muri ake nei me te tika o te nanometer.
