Inqubo Yokulungiselela kanye Nokusungulwa Kobuchwepheshe Kwempuphu Ye-Aluminium Oxide
Uma kukhulunywa ngokuthiimpuphu ye-alumina, abantu abaningi bangase bazizwe bengajwayelene nakho. Kodwa uma kukhulunywa ngezikrini zefoni esizisebenzisa nsuku zonke, izembozo ze-ceramic ezinqoleni zesitimela ezihamba ngesivinini esikhulu, ngisho namathayela okushisa okushisa ezindiza zasemkhathini, ukuba khona kwale mpuphu emhlophe kubalulekile ngemuva kwale mikhiqizo yobuchwepheshe obuphezulu. Njengento "esetshenziswayo yonke indawo" emkhakheni wezimboni, inqubo yokulungiselela i-aluminium oxide powder iye yashintsha kakhulu eminyakeni eyikhulu edlule. Umbhali wake wasebenza endaweni ethile.i-aluminaibhizinisi lokukhiqiza iminyaka eminingi futhi wazibonela ngamehlo akhe ukwenyuka kobuchwepheshe kwale mboni kusukela “ekwenzeni insimbi yendabuko” kuya ekukhiqizeni okuhlakaniphile.
I. “Izimbazo Ezintathu” Zobuciko Bendabuko
Emsebenzini wokulungiselela i-alumina, ochwepheshe abanolwazi bavame ukuthi, “Ukuze umuntu ahlanganyele ekukhiqizweni kwe-alumina, kumelwe abe nolwazi oluphelele ngamasethi amathathu amakhono abalulekile.” Lokhu kubhekisela kumasu amathathu endabuko: inqubo ye-Bayer, inqubo yokusila kanye nenqubo ehlanganisiwe. Inqubo ye-Bayer ifana nokupheka amathambo esitofini sokucindezela, lapho i-alumina e-bauxite incibilika khona esixazululweni se-alkaline ngokushisa okuphezulu kanye nokucindezela okuphezulu. Ngo-2018, lapho sasilungisa umugqa omusha wokukhiqiza e-Yunnan, ngenxa yokuphambuka kokulawula ukucindezela okungu-0.5MPa, ukwakheka kwekristalu kwebhodwe lonke le-slurry kwehlulekile, okwaholela ekulahlekelweni okuqondile kwama-yuan angaphezu kuka-200,000.
Indlela yokusila ifana kakhulu nendlela abantu basenyakatho abenza ngayo ama-noodle. Kudinga ukuthi i-bauxite ne-limestone "kuxutshwe" ngokulingana bese "kubhakwa" ekushiseni okuphezulu kuhhavini ojikelezayo. Khumbula ukuthi uMaster Zhang oseshabhu unekhono eliyingqayizivele. Ngokubuka nje umbala welangabi, anganquma izinga lokushisa ngaphakathi kuhhavini ngephutha elingekho ngaphezu kuka-10℃. Le "ndlela yabantu" yolwazi oluqoqiwe ayizange ithathelwe indawo izinhlelo zokuthwebula izithombe zokushisa ze-infrared kwaze kwaba ngonyaka odlule.
Indlela ehlanganisiwe ihlanganisa izici zalezi ezimbili zangaphambili. Isibonelo, lapho kwenziwa i-hot pot ye-yin-yang, zombili izindlela ze-acidic kanye ne-alkaline zenziwa ngasikhathi sinye. Le nqubo ifaneleka kakhulu ekucubunguleni ama-ore asezingeni eliphansi. Ibhizinisi elithile eSifundazweni saseShanxi likwazile ukwandisa izinga lokusetshenziswa kwe-lean ore ngesilinganiso se-aluminium-silicon esingu-2.5 ngo-40% ngokuthuthukisa indlela ehlanganisiwe.
II. Indlela YokugqashulaUkusungula Izinto Ezintsha Kwezobuchwepheshe
Inkinga yokusetshenziswa kwamandla kobuciko bendabuko ibilokhu iyindaba ebuhlungu embonini. Idatha yemboni kusukela ngo-2016 ikhombisa ukuthi ukusetshenziswa kukagesi okujwayelekile ngethani le-alumina kungama-kilowatt-hours angu-1,350, okulingana nokusetshenziswa kukagesi komndeni isikhathi esingangesigamu sonyaka. "Ubuchwepheshe bokuncibilikisa izinga lokushisa eliphansi" obuthuthukiswe yibhizinisi elithile, ngokungeza ama-catalyst akhethekile, kunciphisa izinga lokushisa lokusabela kusuka ku-280℃ kuya ku-220℃. Lokhu kukodwa konga u-30% wamandla.
Imishini yokulala emanzi engayibona efektri ethile eShandong yaguqula ngokuphelele umbono wami. Le "giant yensimbi" enezitezi ezinhlanu igcina i-mineral powder isesimweni sokulenga ngegesi, inciphisa isikhathi sokuphendula kusukela emahoreni ayi-6 enkambisweni yendabuko kuya emizuzwini engama-40. Okumangalisa nakakhulu uhlelo lwayo lokulawula oluhlakaniphile, olungalungisa amapharamitha enqubo ngesikhathi sangempela njengodokotela wendabuko waseShayina othatha i-pulse.
Ngokuphathelene nokukhiqizwa okuluhlaza, imboni ihlela umbukiso omuhle kakhulu "wokuguqula imfucuza ibe yingcebo". Udaka olubomvu, olwaluyinsalela yemfucuza eyinkinga, manje selungenziwa lube imicu yobumba kanye nezinto zombhede womgwaqo. Ngonyaka odlule, iphrojekthi yokubonisa eyavakashelwa eGuangxi yaze yenza nezinto zokwakha ezingashi ngodaka olubomvu, futhi intengo yemakethe yayiphezulu ngo-15% kuneyemikhiqizo yendabuko.
Iii. Amathuba Angenamkhawulo Entuthuko Yesikhathi Esizayo
Ukulungiswa kwe-nano-alumina kungabhekwa “njengobuciko bokuqopha okuncane” emkhakheni wezinto zokwakha. Imishini yokomisa ebaluleke kakhulu ebonwa elabhorethri ingalawula ukukhula kwezinhlayiya ezingeni lama-molecule, kanti ama-nano-powder akhiqizwayo angcono kakhulu kune-pollen. Le nto, uma isetshenziswa kuma-separator ebhethri le-lithium, ingaphinda kabili impilo yebhethri.
I-microwaveUbuchwepheshe bokushisisa bungikhumbuza i-oven ye-microwave ekhaya. Umehluko ukuthi amadivayisi e-microwave esezingeni lezimboni angafudumeza izinto zibe ngu-1600℃ zingakapheli imizuzu emi-3, futhi ukusetshenziswa kwawo kwamandla kuyingxenye eyodwa kwezintathu kuphela yalawo asetshenziswa ezithandweni zikagesi zendabuko. Okungcono nakakhulu, le ndlela yokushisa ingathuthukisa isakhiwo sezinto ezincane. Izitsha zobumba ze-alumina ezenziwe yinkampani ethile yezempi yezimboni ngazo zinobunzima obufana nobedayimane.
Ushintsho olusobala kakhulu olulethwa ukuguqulwa okuhlakaniphile yisikrini esikhulu egumbini lokulawula. Eminyakeni engamashumi amabili edlule, izisebenzi ezinekhono zazihambahamba egumbini lemishini zinezincwadi zokurekhoda. Manje, intsha ingaqedela yonke inqubo yokuqapha ngokuchofoza okumbalwa nje kwegundane. Kodwa ngokuthakazelisayo, onjiniyela bezinqubo abaphezulu kakhulu sebebe “othisha” besistimu ye-AI, bedinga ukuguqula amashumi eminyaka olwazi lube yi-algorithmic logic.
Ukuguqulwa kusuka ku-ore kuya ku-alumina emsulwa kakhulu akugcini nje ngokuchaza ukusabela ngokomzimba namakhemikhali kodwa futhi kuwukuqiniswa kokuhlakanipha komuntu. Lapho izimboni ezihlakaniphile ze-5G zihlangabezana "nokuhlangenwe nakho kwesandla" kwezingcweti ezingochwepheshe, futhi lapho i-nanotechnology ixoxa nama-oven endabuko, lokhu kuthuthuka kobuchwepheshe okuthathe ikhulu leminyaka akukapheli. Mhlawumbe, njengoba iphepha elimhlophe lakamuva libikezela, isizukulwane esilandelayo sokukhiqizwa kwe-alumina sizoqhubekela "ekukhiqizeni kwezinga le-athomu". Kodwa-ke, kungakhathaliseki ukuthi ubuchwepheshe buhamba kanjani, ukuxazulula izidingo ezingokoqobo nokudala inani langempela kuyizixhumanisi zaphakade zokusungula ubuchwepheshe.
