Indima yokuguqulwa kwe-alumina powder kumashishini abrasive
Abo basebenze kwii-workshops ze-abrasive bayazi ukuba yintloko yokujongana nezinto ezinobunzima obuphezulu - iintlantsi ezivela kwivili lokusila, imikrwelo kwindawo yokusebenza, kunye nokuhla kwezinga lesivuno. Ubuso bomphathi bumnyama kunomzantsi wembiza. Kude kube ngumgubo omhlophe wealumina powderyagxalathelana ukuya kwindawo yedabi, yatsalela ishishini elirhabaxa langena kwixesha elitsha. Namhlanje, makhe sithethe malunga nokuba kutheni le nto ibe "ngumsindisi wokusila" kwishishini lanamhlanje!
1. Unetalente: "igorha eline-hexagonal" kwishishini elinoburharha
I-alumina powder izalwe ukuba ibe ngumntu onzima odla esi sitya serayisi. Iipropathi ezintathu eziqinileyo zityumza ngokuthe ngqo oontanga bayo:
Ubunzima buphezulu: Ukuqina kwe-Mohs kuqala kwi-9.0, okwesibini kuphela kwidayimane. Umzi-mveliso wesixhobo e-Guangdong ulinganisa: Xa usika intsimbi enesantya esiphezulu, ubomi bevili lokusila i-alumina buphindwe ka-3 kuneebrasives eziqhelekileyo. Umfundisi omdala uHuang wathi ephethe umdiza emlonyeni wakhe: “Ndandilitshintsha kathathu ivili lokusila xa ndisika intsimbi exutywe nengxubevange, kodwa ngoku ndikwazi ukuyenza yonke loo nto ngaphandle kokuphefumla!”
Ukucoceka okumangalisayo: i-99.6% α-Al₂O₃ umxholo, ukungcola kwentsimbi kunyanzeliswa ngaphantsi kwe-0.01%. I-Shanghai Semiconductor Factory ilahlekelwe yilahleko: ukusebenzisa i-abrasives enentsimbi ukupholisa ii-wafers, umphezulu wawubukeka njengeepockmarks emva kweenyanga ezintathu; usebenzisa i-alumina powder ukunyanga, ayitshintshi umbala nakwiibhafu ze-asidi.
Uzinzo lwe-Thermal lufana nenja endala: indawo yokunyibilika i-2050℃, i-coefficient yokwandisa i-thermal ephantsi njenge-4.8×10⁻⁶/℃. Umzi-mveliso we-rocket nozzle e-Qingdao uwusebenzisela ukucola i-alloys ezinobushushu obuphezulu, kwaye ukuguquguquka kobungakanani phantsi kwe-1500 ℃ kubume bungaphantsi kwe-6 ububanzi beenwele.
Okumangalisa ngakumbi kukuba inokutshintsha imilo yayo ngamaxesha angama-72 - ukusuka kwi-micron-level flat particles ukuya kwi-nano-level spherical powder, inokuba yingqukuva okanye ithe tyaba njengoko ufuna, kwaye yenzelwe ngokukodwa ukunyanga zonke iintlobo zokungathobeli!
2. Umboniso wenguqu: “Inqanaba logqabhuko-dubulo lweNyukliya” kumabala amathathu amakhulu edabi
I-workshop ye-Semiconductor: Izakhono ze-embroidery ze-Nano-level
Ukupholisha kweSilicon wafer: I-alumina ecaba yi-sliving micropowder phezu komphezulu we-silicon wafer njengokutyibilika, kunye nesantya sokukrwela sehla ngama-70% ngokutyibilika ngokusila endaweni yokuqengqeleka ngokwesiko. Umphathi weSMIC wadanduluka wathi: “Lo msebenzi ubuthathaka ngakumbi kunomhombiso!”
I-Silicon carbide chip: I-Nano-alumina yokupholisha ulwelo i-drill kwi-gap ye-chip, kunye nokusebenza kakuhle kokutshatyalaliswa kobushushu kuphuculwe ngumphumo we-quantum tunnel, kwaye izinga lesivuno likhuphukela kwi-99.98%. Injineli yeprojekthi yawuphulula umfanekiso we-electron we-microscope yaza yaqhayisa ngelithi: “Oku kuchaneka kuphakame kangangokuba nengcongconi emi kuwo kuya kufuneka yahlukane!”
I-Sapphire substrate: I-Submicron alumina ipholisha i-substrate ye-LED kwi-Ra <0.3nm, egudileyo kunesibuko. Umphathi weDongguan Optoelectronics Factory uthe ngovuyo: "Ngoku senza iilensi ze-iPhone, kwaye abahloli be-Apple abafumani siphoso kubo!"
Iworkshop yeemoto: umbulali weendleko kwi-intanethi
I-Aerospace: iingcali ezicela umngeni kakhulu
I-turbine blade mortise kunye ne-tenon processing:Ivili lokugaya iAluminaisebenza kwi-alloy esekelwe kwi-nickel, kwaye inokumelana neeyure ze-100 ngaphandle kokulahlekelwa ngumgubo ngesantya se-2200 rpm. Umqhubi wovavanyo uLao Li wajonga kwiscreen sokujonga wadanduluka esithi: “Ngale ndlela yokuxhathisa, noMusk kufuneka ewugqithise umdiza!”
I-rocket nozzle yangaphakathi yokupholisha eludongeni: I-alumina efakwe i-Nano-coated inciphisa uburhabaxa ukuya kwi-Ra0.01μm, kunye nokusebenza kakuhle kwamafutha kuphuculwe nge-8%. Injineli eyintloko yathi ngamehlo abomvu: “Le nto inye iyodwa inokonga iitoni ezintathu zepetroli nyaka ngamnye!”
3. Ukuhlaselwa kwemveliso yasekhaya: ukusuka "kwintamo exingekile" ukuya "kwi-arm wrestling"
Iibrasives ze-alumina zasekhaya zazisetyenziselwa ukuba "ibali elibuhlungu" - ukuxhatshazwa okungahambi kakuhle, iibhetshi ezingazinzanga, i-nano powder agglomeration efana nesobho se-pimple, kwaye i-market-end-market yayilawulwa yi-American and Japanese company13. Kodwa i-wave ye-semiconductor yasekhaya yanyanzela ukuhlaselwa kweJedi:
Uhlaselo lokuhlambulula: I-factory e-Luoyang iphuhlise i-arc yokulawula ubushushu obukrelekrele, kwaye izinga lokuguqulwa kwesigaba se-α lifikelele kwi-99.95%, kwaye ubunyulu bulingana ne-Showa Denko yaseJapan.
Imetafiziksi yobungakanani besuntswana: Iinkampani zaseZhejiang zisebenzisa abahlalutyi beiturbine ye-AI ukulawula ukuhanjiswa kobungakanani bamasuntswana ngaphakathi kwe ±0.1μm. Abathengi baseKorea balahla imihlathi yabo xa behlola iimpahla: "Le datha ichaneke ngakumbi kunesixhobo!"
Ukuzalwa kwakhona kwenkunkuma: Isiseko seShandong siyayityumza kwaye silungisa kwakhona inkunkumaamavili okusila, kwaye umlinganiselo we-admixture uyancipha ukuya kwi-30%, kwaye iindleko ziyancipha ngama-40%. Umalathisi wendawo yokusebenzela, uLao Zhou, wahleka waza wangxolisa esithi: “Inkunkuma ebikade ilahlwa ngelahleko ngoku ixabiseke ngaphezu kwezinto ezintsha!”
4.Ithafa ledabi elizayo: iindlela ezintathu eziphambili zizinzile
Ulawulo lwe-Nano-level: I-laboratory ye-Hefei ifike ngeteknoloji emnyama - iteknoloji yokubeka i-atomic layer ukubeka "isikrweqe" kwi-powders encinci kunye nokusombulula ingxaki ye-agglomeration. Umphandi waphakamisa isampulu waze waqhayisa esithi: “Ngoku ukupolishwa kwetshiphu kugudileyo kunokuweksa!”
Uguqulo lohlaza: Isityalo saseChongqing sisebenzisa inkqubo yokubuyisela iasidi yenkunkuma ukunciphisa ukukhutshwa kweetoni ezingama-300 zenkunkuma eyingozi ngonyaka. Abantu abasuka kwi-Environmental Protection Bureau beza kutyelela baza babetha ngobhontsi besithi: “Uza kuwuyeka umzi-mveliso wogutyulo!”
Izixhobo zokusila ezihlakaniphile: Umzi-mveliso eZhengzhou ufake inzwa yoxinzelelo kwivili lokusila ukuze uhlengahlengise iiparamitha zokugaya ngexesha langempela. U-Xiao Liu, igcisa elazalelwa kwiminyaka yoo-1990, wachwetheza kwikhibhodi waza waqhayisa: “Ngoku ukulungisa iiparamitha kulula kunokudlala imidlalo, kwaye izinga lesivuno lifikelele kwi-99.8%!”
