Kukonzekera Njira ndi Zamakono Zamakono za Aluminium Oxide powder

Zikafikaalumina ufa, anthu ambiri angaone kuti sadziwa. Koma zikafika pazithunzi za foni yam'manja yomwe timagwiritsa ntchito tsiku lililonse, zokutira za ceramic m'maboti othamanga kwambiri, komanso matailosi otenthetsera kutentha kwa ma shuttles, kupezeka kwa ufa woyera uku ndikofunikira kwambiri kuseri kwa zinthu zapamwambazi. Monga "zinthu zapadziko lonse" m'munda wa mafakitale, njira yokonzekera ufa wa aluminium oxide yasintha kwambiri m'zaka zapitazi. Wolembayo nthawi ina adagwira ntchito inayakealuminiyamukwa zaka zambiri ndipo adawona ndi maso ake kudumpha kwaukadaulo kwamakampaniwa kuchokera ku "kupanga zitsulo zachikhalidwe" mpaka kupanga mwanzeru.

I. “Nkhwangwa Zitatu” za Luso Lakale

Pamsonkhano wokonzekera alumina, ambuye odziwa zambiri nthawi zambiri amati, "Kuti munthu atenge nawo mbali pakupanga alumina, munthu ayenera kukhala ndi maluso atatu ofunikira." Izi zikutanthauza njira zitatu zachikhalidwe: ndondomeko ya Bayer, ndondomeko ya sintering ndi ndondomeko yophatikizana. Njira ya Bayer ili ngati mafupa ophikira mu chophika chokakamiza, pomwe alumina mu bauxite amasungunuka mu njira ya alkaline chifukwa cha kutentha kwambiri komanso kuthamanga kwambiri. Mu 2018, pamene ife anali debugging latsopano kupanga mzere ku Yunnan, chifukwa kuthamanga ulamuliro kupatuka kwa 0.5MPa, crystallization mphika wonse wa slurry analephera, kuchititsa imfa mwachindunji pa 200,000 yuan.

Njira yopangira sinter ili ngati momwe anthu akumpoto amapangira Zakudyazi. Pamafunika bauxite ndi miyala ya laimu kuti "zisakanizidwe" molingana ndi "kuphika" pa kutentha kwakukulu mu ng'anjo yozungulira. Kumbukirani kuti Master Zhang mumsonkhanowu ali ndi luso lapadera. Pongoyang'ana mtundu wa lawi lamoto, amatha kudziwa kutentha mkati mwa ng'anjoyo ndi zolakwika zosapitirira 10 ℃. "Njira yachidziwitso" yodziŵika bwinoyi sinalowe m'malo ndi makina owonetsera matenthedwe a infrared mpaka chaka chatha.

Njira yophatikizika imaphatikiza zinthu ziwiri zakale. Mwachitsanzo, popanga poto yotentha ya yin-yang, njira za acidic ndi zamchere zimachitika nthawi imodzi. Njira imeneyi ndi yabwino kwambiri pokonza ores otsika kwambiri. Bizinesi ina m'chigawo cha Shanxi idakwanitsa kukulitsa kuchuluka kwa ma ore osawonda ndi aluminiyamu-silicon chiŵerengero cha 2.5 ndi 40% pokonza njira yophatikiza.

Ii. Njira YopulumutsiraTekinoloje yatsopano

Nkhani yogwiritsa ntchito mphamvu yaukadaulo wanthawi zonse yakhala ikuvutitsa m'makampani. Deta yamakampani kuchokera ku 2016 ikuwonetsa kuti pafupifupi magetsi ogwiritsa ntchito tani imodzi ya alumina ndi ma kilowatt-maola a 1,350, ofanana ndi kugwiritsa ntchito magetsi kwanyumba kwa theka la chaka. "Tekinoloje yochepetsera kutentha pang'ono" yopangidwa ndi bizinesi inayake, powonjezera zida zapadera, imachepetsa kutentha kwa 280 ℃ mpaka 220 ℃. Izi zokha zimapulumutsa 30% ya mphamvu.

Zida za bedi zamadzimadzi zomwe ndidaziwona mufakitale ina ku Shandong zidasinthiratu malingaliro anga. "Chimphona chachitsulo" chokhala ndi nsanjika zisanu chimasunga ufa wamchere m'malo oimitsidwa kudzera pa gasi, kuchepetsa nthawi yochitirapo kanthu kuchokera ku maola 6 mwachikhalidwe mpaka mphindi 40. Chodabwitsa kwambiri ndi njira yake yowongolera mwanzeru, yomwe imatha kusintha magawo munthawi yeniyeni monga momwe dokotala waku China amachitira.

Pankhani ya kupanga zobiriwira, makampaniwa akupanga chiwonetsero chodabwitsa cha "kusandutsa zinyalala kukhala chuma". Matope ofiira, omwe kale anali zinyalala zovuta, tsopano atha kupangidwa kukhala ulusi wa ceramic ndi zipangizo zapamsewu. Chaka chatha, ntchito yowonetsera yomwe idayendera ku Guangxi idapanganso zida zomangira zosapsa ndi moto kuchokera kumatope ofiira, ndipo mtengo wamsika unali 15% wokwera kuposa wazinthu zakale.

Kukonzekera kwa nano-aluminium kumatha kuonedwa ngati "zojambula zazing'ono" m'munda wa zipangizo. Zipangizo zowumitsa kwambiri zomwe zimawonedwa mu labotale zimatha kuwongolera kukula kwa tinthu tating'onoting'ono pamlingo wa molekyulu, ndipo nano-ufa wopangidwa ndi wabwino kwambiri kuposa mungu. Izi, zikagwiritsidwa ntchito mu olekanitsa batire la lithiamu, zimatha kuwirikiza kawiri moyo wa batri.

Microwaveukadaulo wa sintering umandikumbutsa za uvuni wa microwave kunyumba. Kusiyana kwake ndikuti zida za microwave za mafakitale zimatha kutentha zida mpaka 1600 ℃ mkati mwa mphindi zitatu, ndipo kugwiritsa ntchito mphamvu ndi gawo limodzi mwa magawo atatu a ng'anjo zachikhalidwe zamagetsi. Ngakhale bwino, Kutentha njira imeneyi akhoza kusintha microstructure zakuthupi. Zoumba za alumina zopangidwa ndi gulu lina lankhondo zomwe zili nazo zimakhala ndi kulimba kofanana ndi diamondi.

Kusintha kodziwikiratu komwe kumabwera chifukwa cha kusintha kwanzeru ndi chophimba chachikulu muchipinda chowongolera. Zaka 20 zapitazo, antchito aluso ankayendayenda m'chipinda chosungiramo zipangizo ndi mabuku. Tsopano, achinyamata akhoza kumaliza ntchito yonse yowunika ndikungodina pang'ono pa mbewa. Koma chochititsa chidwi, mainjiniya apamwamba kwambiri m'malo mwake akhala "aphunzitsi" a kachitidwe ka AI, akufunika kusintha zaka zambiri kukhala malingaliro a algorithmic.

Kusintha kuchokera ku miyala yamtengo wapatali kupita ku alumina yoyera kwambiri sikungotanthauzira zochitika zakuthupi ndi zamankhwala komanso kuwunikira kwanzeru zaumunthu. Mafakitole anzeru a 5G akakumana ndi "zochita zamanja" za amisiri apamwamba, ndipo nanotechnology ikamakambirana ndi ng'anjo zachikhalidwe, kusinthika kwaukadaulo kwazaka zana sikunathe. Mwina, monga momwe pepala loyera lamakampani laposachedwa likuneneratu, m'badwo wotsatira wopanga alumina udzapita ku "kupanga ma atomiki". Komabe, ziribe kanthu momwe teknoloji imadumphira, kuthetsa zosowa zenizeni ndikupanga phindu lenileni ndizogwirizanitsa kosatha za luso lamakono.
