Te tūranga hurihuri o te paura alumina i roto i te umanga whakakoi
E mōhio ana te hunga kua mahi i roto i ngā awheawhe whakakoi he uaua te mahi ki ngā rauemi pakeke – ngā mura o te wira huri, ngā karawarawa i te wāhi mahi, me te hekenga o te tere hua. He mangu ake te mata o te rangatira i te raro o te kohua. Kia tae rā anō ki te paura mā opaura konumohei tere atu ki te papa pakanga, i tōia te umanga whakakoi ki tētahi wā hou. I tēnei rā, me kōrero tātou mō te take i riro ai tēnei mea hei "kaiwhakaora huri" mō te umanga hou!
1. Pūkenga: "toa hexagonal" i roto i te umanga whakakoi
I whānau mai te paura konumohe hei tangata pakari e kai ana i tēnei peihana raihi. E toru ngā āhuatanga pakari e tino patu tika ana i ōna hoa:
He teitei te pakeke: Ka tīmata te pakeke o te Mohs i te 9.0, tuarua ki te taimana. I inehia e tētahi wheketere taputapu i Guangdong: I te wā e tapahi ana i te maitai tere-rahi, e toru ngā wā te roa o te ora o ngā wira huri alumina i ērā o ngā mea whakakoi noa. I mea te rangatira tawhito a Huang me te hikareti i roto i tōna waha: "I mua, e toru ngā wā i whakawhitia ai e au te wira huri i te wā e tapahi ana i te maitai koranu, engari ināianei ka taea e au te mahi katoa me te kore e manawa!"
He tino parakore: 99.6% te ihirangi α-Al₂O₃, kua pehia ngā poke rino ki raro iho i te 0.01%. I pāngia te Shanghai Semiconductor Factory e te mate: mā te whakamahi i ngā mea whakakoi kei roto he rino hei whakakanapa i ngā papa, i rite te mata ki ngā tohu i muri i ngā marama e toru; mā te whakamahi i te paura alumina hei rongoā, kāore e rerekē te tae ahakoa i roto i ngā kaukau waikawa.
He rite te pumau o te wera ki te kurī tawhito: ko te ira rewa he 2050℃, ko te tauwehenga whānui wera he iti iho i te 4.8×10⁻⁶/℃. E whakamahia ana tēnei e tētahi wheketere pūwero rōkete i Qingdao hei huri i ngā koranu pāmahana teitei, ā, ko te rerekētanga o te rahi i raro i te taiao 1500℃ he iti iho i te 6 ngā wā o te whānui o te makawe.
Ko te mea whakamiharo ake, ka taea e ia te whakarerekē i tōna āhua kia 72 ngā wā – mai i ngā matūriki papatahi taumata-micron ki te paura porowhita taumata-nano, ka taea te porowhita, te papatahi rānei e ai ki tāu e hiahia ana, ā, he mea hanga motuhake hei rongoā i ngā momo tutu katoa!
2. Te tirohanga hurihuri: "Te mahi taumata-pahūtanga karihi" i roto i ngā papa pakanga nui e toru
Awheawhe hiko-ārahi: Ngā pūkenga whakairo taumata-nano
Te whakakanapa i te papara silicon: Ka pania te paura iti alumina papatahi ki runga i te mata o te papara silicon, pērā i te reti reti, ā, ka heke te tere o te rakuraku mā te 70% mā te huri retireti hei utu mō te huri noa. Ka karanga te tohunga o SMIC: "He tino ātaahua ake tēnei mahi i te whakairo!"
Maramara karawiti hiko: Ka pokaia e te wai whakakanapa nano-alumina te āputa maramara, ā, ka whakapaitia te pai o te whakamararatanga wera e te pānga kauhanga irahiko, ā, ka piki ake te tere hua ki te 99.98%. I pārekareka te miihini kaupapa ki te pikitia o te karu hikohiko, ā, i whakamanamana: "He tino teitei tēnei tika, ā, me pakaru noa te waeroa e tū ana i runga!"
Papa hapaira: Ka whakakanapahia e te submicron alumina te papa LED ki te Ra<0.3nm, he maeneene ake i te whakaata. I kī harikoa te rangatira o te Dongguan Optoelectronics Factory: "Inaianei kei te hanga mātou i ngā karaihe iPhone, ā, kāore e kitea he hapa e ngā kaitirotiro Apple!"
Awheawhe motuka: he kaipatu utu ipurangi
Rererangi: ngā tohunga wero nui
Te tukatuka i te mata o te tāpine me te mortise me te tenon:Wira huri konumoheKa mahi i runga i te koranu nikara, ā, ka taea e ia te tu atu mō ngā hāora 100 me te kore e ngaro te paura i te tere o te 2200 rpm. I titiro matatau te taraiwa whakamātautau a Lao Li ki te mata aroturuki, ā, ka karanga: "Me tēnei ātete kakahu, me tuku hikareti anō hoki a Musk!"
Te whakakanapa i te pakitara o roto o te pūwero rōkete: Ka whakaitihia e te paura alumina kua pania ki te nano te taratara ki te Ra0.01μm, ā, ka whakapaitia te whai huatanga o te wahie mā te 8%. I mea te miihini matua me ngā kanohi whero: "Ka taea e tēnei taonga kotahi anake te penapena i te toru tana o te wahie i ia tau!"
3. Te whakaekenga ā-rohe i te hanga o roto: mai i te "kaki piri" ki te "nonoke ringa"
He "kōrero pouri" ngā mea whakakoi alumina ā-whare i mua – he ātete ngoikore ki te kakahu, he puranga kore pumau, he kohikohinga paura nano pērā i te hupa pimple, ā, ko te mākete utu nui i puritia e ngā kamupene o Amerika me Hapanihi13. Engari nā te ngaru o te kimi i ngā mea semiconductor i akiaki i tētahi whakaekenga a Jedi:
Whakaekenga parakore: Kua whakawhanakehia e tētahi wheketere i Luoyang tētahi pūnaha whakahaere pāmahana atamai mō te oumu pewa, ā, kua eke te tere tahuritanga ā-wāhanga α ki te 99.95%, ā, he rite te parakore ki te Showa Denko o Hapani.
Te matatika o te rahi o te matūriki: Ka whakamahia e ngā kamupene o Zhejiang ngā whakarōpūtanga tāpine AI hei whakahaere i te tohatoha rahi o te matūriki i roto i te ±0.1μm. I hinga ngā kauae o ngā kaihoko Korea i te tirotiro i ngā taonga: "He tika ake tēnei raraunga i te taputapu kite!"
Te whānautanga o ngā para: Ka kuru, ka whakapai anō te turanga Shandong i ngā parangā wira huri, ā, ka whakaitihia te ōwehenga tāpiri ki te 30%, ā, ka whakaitihia te utu mā te 40%. Ka kata te kaiwhakahaere o te awheawhe, a Lao Zhou, ka riri: "Ko te para i mua ka tukuna noa atu, he nui ake te uara i ngā rauemi hou!"
4. Te papa pakanga o te heke mai: e toru ngā au nui e pumau ana
Mana whakahaere taumata-nano: Kua hangaia e te taiwhanga o Hefei te hangarau pango – te hangarau whakatakoto paparanga ngota hei whakatakoto i te "pūeru" ki runga i ngā paura moroiti me te whakaoti rapanga o te kohikohinga. I pupuri ake te kairangahau i te tauira me te whakamanamana: "Inaianei he maeneene ake te oro maramara i te waxing!"
Huringa Kakariki: Ka whakamahia e te wheketere o Chongqing tētahi pūnaha whakaora waikawa para hei whakaiti i te tukunga o te 300 tana o ngā para kino i ia tau. I tae mai ngā tāngata o te Tari Tiaki Taiao ki te toro mai, ā, i tautoko mai rātou: "Ka whakamutua e koutou te wheketere maimoatanga para!"
Ngā taputapu huri atamai: I tāutahia e tētahi wheketere i Zhengzhou tētahi pūoko pēhanga ki runga i te wira huri hei whakarite i ngā tawhā huri i te wā tonu. I pato a Xiao Liu, he tohunga hangarau i whānau i ngā tau 1990, ki te papapātuhi, ā, i whakamanamana ia: "Inaianei he māmā ake te whakarite i ngā tawhā i te tākaro kēmu, ā, kua eke te reiti hua ki te 99.8%!"
