Njira Yokonzekera ndi Kupangidwanso kwa Ukadaulo wa Ufa wa Aluminium Oxide

Ponena zaufa wa alumina, anthu ambiri angamve kuti sakuzidziwa bwino. Koma pankhani ya mafoni omwe timagwiritsa ntchito tsiku lililonse, zophimba zadothi m'magalimoto othamanga kwambiri, komanso matailosi oteteza kutentha a ma space shuttles, kupezeka kwa ufa woyera uwu ndikofunikira kwambiri pazinthu zamakono izi. Monga "zinthu zonse" m'mafakitale, njira yokonzekera ufa wa aluminiyamu oxide yasintha kwambiri m'zaka zana zapitazi. Wolembayo adagwirapo ntchito mu kampani inayake.aluminiyamukampani yopanga zinthu kwa zaka zambiri ndipo adawona ndi maso ake kusintha kwaukadaulo kwa makampaniwa kuyambira pa "kupanga zitsulo zachikhalidwe" kupita ku kupanga zinthu mwanzeru.

I. "Nkhwangwa Zitatu" za Ukadaulo Wachikhalidwe

Mu msonkhano wokonzekera alumina, akatswiri odziwa bwino ntchito nthawi zambiri amanena kuti, "Kuti munthu alowe nawo mu kupanga alumina, ayenera kukhala ndi luso lofunikira m'magulu atatu." Izi zikutanthauza njira zitatu zachikhalidwe: njira ya Bayer, njira yoyeretsera ndi njira yophatikizana. Njira ya Bayer ili ngati kuwotcha mafupa mu chitofu chopondereza, komwe alumina mu bauxite imasungunuka mu yankho la alkaline kudzera mu kutentha kwambiri komanso kuthamanga kwambiri. Mu 2018, pamene tinkakonza mzere watsopano wopangira ku Yunnan, chifukwa cha kusintha kwa mphamvu ya 0.5MPa, kupangika kwa crystallization ya mphika wonse wa slurry kunalephera, zomwe zinapangitsa kuti pakhale kutayika kwa yuan yoposa 200,000.

Njira yopangira zinthu zoyeretsera zinthu ili ngati mmene anthu akumpoto amapangira Zakudya za m'madzi. Zimafunika kuti bauxite ndi limestone "zisakanizidwe" mofanana kenako "ziphikidwe" kutentha kwambiri mu uvuni wozungulira. Kumbukirani kuti Master Zhang mu workshop ali ndi luso lapadera. Pongoyang'ana mtundu wa lawi, amatha kudziwa kutentha mkati mwa uvuni ndi cholakwika chosapitirira 10℃. "Njira yachikhalidwe" iyi yosonkhanitsidwa sinalowe m'malo ndi makina ojambulira kutentha kwa infrared mpaka chaka chatha.

Njira yophatikizana imaphatikiza mawonekedwe a ziwiri zoyambirira. Mwachitsanzo, popanga yin-yang hot pot, njira zonse ziwiri za acidic ndi alkaline zimachitika nthawi imodzi. Njirayi ndi yoyenera kwambiri pokonza miyala yamtengo wapatali. Kampani ina ku Shanxi Province inakwanitsa kuwonjezera kuchuluka kwa kugwiritsa ntchito miyala yamtengo wapatali ndi chiŵerengero cha aluminiyamu-silicon cha 2.5 ndi 40% mwa kukonza njira yophatikizana.

II. Njira YotulukiraZatsopano pa Ukadaulo

Nkhani yokhudza kugwiritsa ntchito mphamvu pogwiritsa ntchito luso lachikhalidwe nthawi zonse yakhala yovuta kwambiri m'makampaniwa. Deta ya mafakitale kuyambira mu 2016 ikuwonetsa kuti magetsi omwe amagwiritsidwa ntchito pa tani imodzi ya alumina ndi 1,350 kilowatt-hours, zomwe ndi zofanana ndi magetsi omwe amagwiritsidwa ntchito m'nyumba kwa theka la chaka. "Ukadaulo wosungunuka wochepa kutentha" womwe wapangidwa ndi kampani inayake, powonjezera ma catalyst apadera, umachepetsa kutentha kwa reaction kuchokera pa 280℃ mpaka 220℃. Izi zokha zimapulumutsa 30% ya mphamvu.

Zipangizo zogona zothira madzi zomwe ndinaziona ku fakitale ina ku Shandong zinasintha kwambiri malingaliro anga. "Chimphona chachitsulo" chazitali zisanu ichi chimasunga ufa wa mchere mu mpweya woyimitsidwa, kuchepetsa nthawi yochitira zinthu kuchokera pa maola 6 mu njira yachikhalidwe mpaka mphindi 40. Chodabwitsa kwambiri ndi njira yake yowongolera yanzeru, yomwe imatha kusintha magawo a njira nthawi yeniyeni monga momwe dokotala wachikhalidwe waku China amaonera kugunda kwa mtima.

Ponena za kupanga zinthu zobiriwira, makampaniwa akuwonetsa bwino kwambiri "kusandutsa zinyalala kukhala chuma". Matope ofiira, omwe kale anali zinyalala zovuta, tsopano akhoza kupangidwa kukhala ulusi wa ceramic ndi zipangizo zomangira msewu. Chaka chatha, polojekiti yowonetsera yomwe idapita ku Guangxi idapanganso zipangizo zomangira zosapsa ndi moto kuchokera ku matope ofiira, ndipo mtengo wamsika unali wokwera ndi 15% kuposa wa zinthu zachikhalidwe.

III. Mwayi Wosatha wa Chitukuko cha M'tsogolo

Kukonzekera kwa nano-alumina kungawonedwe ngati "luso lojambula zinthu zazing'ono" pakupanga zinthu. Zipangizo zowumitsa zodziwika bwino zomwe zimapezeka mu labotale zimatha kuwongolera kukula kwa tinthu tating'onoting'ono pamlingo wa mamolekyulu, ndipo ufa wa nano-ufa womwe umapangidwa ndi wabwino kwambiri kuposa mungu. Zinthuzi, zikagwiritsidwa ntchito mu zolekanitsa mabatire a lithiamu, zimatha kuwirikiza kawiri moyo wa batri.

MaikulowevuUkadaulo wothira mafuta umandikumbutsa za uvuni wa microwave kunyumba. Kusiyana kwake ndi kwakuti zipangizo za microwave zamakampani zimatha kutentha zipangizo kufika pa 1600℃ mkati mwa mphindi zitatu, ndipo mphamvu zomwe zimagwiritsidwa ntchito ndi gawo limodzi mwa magawo atatu okha a ng'anjo zamagetsi zachikhalidwe. Chabwino kwambiri, njira yotenthetsera iyi imatha kukonza kapangidwe kake ka zinthuzo. Zoumba za alumina zopangidwa ndi kampani inayake yankhondo yamakampani pogwiritsa ntchito izi zimakhala ndi kuuma kofanana ndi kwa diamondi.

Kusintha koonekeratu komwe kumachitika chifukwa cha kusintha kwanzeru ndi chinsalu chachikulu chomwe chili mu chipinda chowongolera. Zaka makumi awiri zapitazo, antchito aluso ankayendayenda m'chipinda chogwiritsira ntchito zida ndi mabuku ojambulira. Tsopano, achinyamata amatha kumaliza kuyang'anira njira yonse ndi kudina pang'ono kwa mbewa. Koma chosangalatsa n'chakuti, mainjiniya akuluakulu a njira m'malo mwake akhala "aphunzitsi" a dongosolo la AI, akufunika kusintha zaka zambiri zaukadaulo kukhala malingaliro a algorithmic.

Kusintha kuchoka ku miyala kupita ku alumina yoyera kwambiri sikungotanthauza kutanthauzira kwa zochita zakuthupi ndi zamakemikolo komanso kupangika kwa nzeru za anthu. Pamene mafakitale anzeru a 5G akumana ndi "zokumana nazo ndi manja" za akatswiri aluso, komanso pamene nanotechnology ikulankhulana ndi uvuni wachikhalidwe, kusintha kwaukadaulo kwa zaka zana kumeneku sikudzatha. Mwina, monga momwe pepala loyera lamakampani aposachedwa limaneneratu, mbadwo wotsatira wa kupanga alumina udzapita ku "kupanga kwa atomiki". Komabe, mosasamala kanthu za momwe ukadaulo ungakwerere, kuthetsa zosowa zenizeni ndikupanga phindu lenileni ndiye njira zosatha zopangira zatsopano zaukadaulo.
