Muhimmiyar rawar alumina foda a cikin kayan haɓakawa

Wadanda suka yi aiki a cikin tarurrukan tarurruka sun san cewa wannan kasuwancin ya fi dacewa da kayan aiki fiye da tanderun alchemy na Taishang Laojun - zafin jiki dole ne ya iya tsayayya da gasa na 2000 ℃, kuma acid da alkali lalata dole ne su iya jure wa baftisma na aqua regia. Idan kuna son faɗin wane abu zai iya zama karko kamar tsohon kare a cikin wannan gwajin “matakin jahannama”,alumina fodatabbas shine mafi kyawun zabi. Wannan tari na farin foda ya dubi talakawa, amma shine "jarumin hexagonal" a cikin masana'antar refractory. A yau, bari mu dubi dalilin da yasa za'a iya sanya shi a cikin tanderun masana'antu.

Ⅰ. "Hardcore Halayen" tare da cikakkun abubuwan basira 139

Ikonalumina fodayana farawa da "gatura guda uku". Da farko dai, wurin narkewar wannan abu ya kai 2050 ℃, wanda ya fi juriyar konewa fiye da kogon zinare na Sun Wukong. Zhang, ƙwararren masani a masana'antar ƙarfe a Shandong, ya taɓa cewa: "Zazzabi a cikin tander ɗinmu yana ƙaruwa zuwa 1800 ℃, amma tubalin alumina ba ya canzawa. Sun fi tanderun Alchemy na Ubangiji Kitchen!"

Tsawon sinadarai ya ma fi na musamman. Tankunan ajiya na sulfuric acid na Ningbo Chemical Shuka ana lullube su da alumina, har ma da ripple ba ya bayyana bayan an jiƙa shi a cikin acid mai ƙarfi tare da ƙimar pH na 1 na rabin shekara. Ingancin inspector Wang ya yi alfahari da samfurin: "Tare da wannan juriyar lalata, har Taishang Laojun zai mika tsabar kudin kasar Sin!"

Juriya na zaizayar slag ya ma fi wuce gona da iri. Bayan sel electrolytic na ƙungiyar masana'antar aluminium a cikin Henan an maye gurbinsu tare da kayan haɓaka na tushen alumina, rayuwar sabis ɗin su ta ƙaru kai tsaye daga watanni 3 zuwa shekaru 2. Daraktan bita Li ya lissafta da sigari a bakinsa: "Kudin da aka adana ya isa ya maye gurbin saitin na'urorin sanyaya iska na tsakiyar masana'anta!"

II. "Master of Form" tare da canje-canje 72 267

Lokacin da alumina foda ke wasa "Metamorphosis", har ma da Sarkin biri ya kira shi Jagora. Nano-alumina foda, fasaha na baƙar fata, na iya sa ƙarfin kayan haɓakawa ya fi ƙarfin ƙarfafawa. Bayanai daga dakin gwaje-gwaje a Shenzhen sun nuna cewa ƙara 5% nano-alumina na iya ninka taurin kayan kuma ya rage zafin jiki da 200 ℃. Wani mai bincike Xiao Liu ya ture gilashin sa ya ce: "Kamar allurar super serum a cikin kayan!"

Alumina mai aikiana amfani da shi akai-akai. Wata masana'anta mai jujjuyawa a Jiangsu tana amfani da ita don haɗe simintin ƙarfe, kuma ruwa yana da kyau kamar shayin madara. Ba a ma maganar adadin ruwa ya yanke da kashi 30%, yawancin samfurin da aka gama yana kusa da rami na baki. Jagora Lao Zhao ya yi fahariya da hoton na'urar duban na'urar lantarki: "Wannan tsarin yana da yawa sosai har ma tururuwa za su yi asara idan sun shiga!"

Haɗuwa da ƙananan foda na nau'i-nau'i daban-daban sun fi ban mamaki. Cibiyar bincike a Changchun ta gano cewa ana inganta juriya ta thermal kai tsaye ta hanyar hada 1μm da 5μm alumina foda a cikin "3: 7" rabo. Babban barbashi na iya jure lalacewa, ƙananan ɓangarorin na iya cike giɓi, kuma haɗuwa ba ta da lahani!

Ⅲ. "Lokaci mai haske" a ainihin wurin fama 4910

A cikin da'irar ƙarfe da ƙarfe na ƙarfe, alumina foda shine "kayan aikin kariyar tanderu". Bayan da fashewar tanderun tanderu na wata masana'antar karafa a lardin Hebei ta kasance mai dogaro da siminti na alumina, rayuwar sabis ɗin ta ya ƙaru daga tanderu 200 zuwa tanderu 800. Lao Zhou, ma'aikacin tanderun, ya lallaba bangon tanderun ya yi dariya: "Yanzu wannan tanderun ta fi na dafa girkina mai ɗorewa!"

Masana'antar petrochemical ta kai wani sabon matsayi. Bayan da aka maye gurbin sashin matatar matatar mai a Qingdao da labulen alumina da ke jure lalacewa, an tsawaita da'irar kulawa daga watanni 3 zuwa shekara 1. Manajan kayan aiki Lao Ma ya koka da bindigar walda: “Yanzu ba ni da aiki don tsaftace kayan aikin kowace rana, kuma kuɗina ya kusa ƙarewa!”

Ⅳ. "Tsaron Makamai" na haɓaka fasaha 2610

Yanzu wasa tare da alumina foda, girmamawa yana kan "ikon matakin nano". Wani dakin gwaje-gwaje a birnin Beijing ya samar da fasahar “atomic dispersion”, wanda ke sa aikin foda na alumina ya fi aiki fiye da na matashi. The sintering zafin jiki an rage zuwa 300 ℃, da makamashi amfani ne kai tsaye yanke a cikin rabin. Wani mai bincike Lao Wang ya yi fahariya: “Yanzu harba murhu kamar yin burodi ne, kuma yanayin zafin jiki ya fi tandana daidai!”

Yadda za a yi wasa tare da kayan haɗin gwiwar ya fi ban sha'awa. Wani kamfani a Xi'an yana haɗa foda alumina tare da silicon carbide don samar da tubalin da ke jujjuya zafin zafi da zaizayar ƙasa. Jagora Lao Zhou ya girgiza kai yayin da yake taba sabon kayan aikin: "Fasahar zamani ta kawar da dukkan ayyukan Lu Ban!"

Daga tanderun alchemy na Taishang Laojun zuwa tanderun narkewa na masana'antar zamani, alumina foda ya tabbatar da ƙarfi: kawun ku koyaushe kawu ne! Wannan tulin farin foda ya huda rami a cikin aikin silin da kayan da ke jujjuyawa. Masanan a cikin masana'antar duk sun ce ba tare da foda alumina ba, kayan haɓakawa za su sake komawa shekaru 30. Idan wannan yanayin ya ci gaba, har ma da murhun barbecue na iya yin amfani da suturar juzu'i na sararin samaniya wata rana - bayan haka, waɗanda ba sa son murhun barbecue ɗin nasu ya kasance a kan matakin daidai da shukar ƙarfe.fashewa tanderu?
