Doorka kacaanka ee budada alumina ee warshadaha abrasive
Kuwa ka soo shaqeeyay aqoon-is-weydaarsiyada xajinta waxay og yihiin inay madax-xanuun tahay si ay ula tacaalaan qalabka adag ee adag - dhimbiil ka yimaada giraangiraha shiida, xoqidda goobta shaqada, iyo hoos u dhaca heerka wax-soo-saarka. Wejiga madaxa ayaa ka madow dheriga guntiisa. Ilaa budada cad eebudada aluminiumwaxay u soo yaaceen goobta dagaalka, waxay u soo jiidatay warshadihii xajistay xilli cusub. Maanta, aan ka hadalno sababta ay tani u noqotay "badbaadiyaha wax shiida" ee warshadaha casriga ah!
1. Kartida leh: "Dagaalyahano laba geesood ah" ee warshadaha abrasive
Budada alumina waxay u dhalatay inuu noqdo nin adag oo cuna weelkan bariiska ah. Saddexda guri ee adag ayaa si toos ah u burburiya asxaabteeda:
Adaggu waa sarreeyaa: adkaanta Mohs waxay ka bilaabataa 9.0, ka labaad oo kaliya dheeman. Warshad qalabeed oo ku taal Guangdong ayaa la cabbiray: Marka la jarayo birta xawaaraha sare leh, nolosha taayirrada aluminiumku wax shiidi karaan waxay 3 jeer ka badan tahay abrasives caadiga ah. Master-kii hore ee Huang ayaa yidhi isagoo sigaar afkiisa ku jira: " Saddex jeer ayaan beddeli jiray giraangiraha wax lagu shiidi jiray marka aan jarayo birta alloy-ga, laakiin hadda waan samayn karaa si kasta anigoon neefsanin!"
Nadiifinta cajiibka ah: 99.6% α-Al₂O₃ ka kooban, wasakhda birta ayaa la xakameeyey in ka yar 0.01%. Warshada Semiconductor ee Shanghai waxaa soo gaaray khasaare: iyadoo la isticmaalayo xabag bir ku jirta si loo nadiifiyo maraqyada, dusha sare wuxuu u ekaa boorsooyin saddex bilood ka dib; iyadoo la isticmaalayo budada alumina si loo daaweeyo, ma beddeleyso midabka xitaa qubeyska aashitada.
Xasiloonida kulaylku waa sida eey duug ah: barta dhalaalaysa 2050 ℃, isku xidhka balaadhinta kulaylka sida ugu hooseeya 4.8 × 10⁻⁶/℃. Warshad biibiile ah oo ku taal Qingdao waxay u isticmaashaa inay shiido alloys heerkul sarreeya, cabirka isbedbedelka ee ka hooseeya 1500 ℃ deegaanka wuxuu ka yar yahay 6 jeer dhexroorka timaha.
Waxa ka sii yaab badan in ay beddeli karto qaabkeeda 72 jeer - laga bilaabo qaybo fidsan heerka micron ilaa budada spherical heerka nano, waxay noqon kartaa wareegsan ama fidsan sidaad rabto, waxaana si gaar ah loogu talagalay in lagu daaweeyo dhammaan noocyada caasinimada!
2. Goobta kacaanka: "Waxqabadka heerka qaraxa nukliyeerka" ee saddexda goobood ee dagaalka
Semiconductor workshop: Xirfadaha daabacaadda heerka Nano
Silikoon wafer polishing: Flat alumina micropowder skims dusha sare ee wafer silikon sida barafka, iyo heerka xoqin hoos u 70% by simbiriirixan shiidi halkii rogid dhaqameed. Sayidka SMIC ayaa ku dhawaaqay: "Shaqadani way ka jilicsan tahay daabacaadda!"
Chip carbide silicon: Nano-alumina polishing dareere wuxuu geliyaa farqiga jajabka, iyo waxtarka daadinta kulaylka waxaa hagaajiyay saamaynta tunnel-ka quantum, iyo heerka wax-soo-saarku wuxuu kor u kacayaa 99.98%. Injineerkii mashruucu wuxuu salaaxay sawirka mikroskoob ee elektarooniga ah wuxuuna ku faanay: "Saaxnimadani aad bay u sarraysaa oo xataa kaneecada ku dul taagan way kala go'aysaa!"
Substrate-ka Sapphire: Submicron alumina wuxuu dhalaaliyaa substrate-ka LED ilaa Ra<0.3nm, kaas oo ka siman muraayadda. Maamulaha Warshada Dongguan Optoelectronics Factory ayaa si farxad leh u yiri: "Hadda waxaan sameyneynaa muraayadaha iPhone-ka, baarayaasha Apple-na khalad kuma heli karaan iyaga!"
Aqoon-is-weydaarsiga baabuurta: Kharashka dilaaga online
Aerospace: xirfadlayaasha loolan adag
Mashiinka daabka marawaxadaha iyo farsamaynta teendhada:Alumina shiida giraangirahawuxuu ku shaqeeyaa daawaha nikkel-ku-saleysan, wuxuuna adkeysan karaa 100 saacadood iyadoo aan lumin budada xawaaraheeda 2200 rpm. Darawalka tijaabada ee Lao Li ayaa eegay shaashada la socodka oo ku qayliyay: "Xidashadan iska caabbinta, xitaa Musk waa inuu dhaafaa sigaarka!"
Duubista gantaalaha ee gidaarka gudaha dhalaalaysa: budada alumina ee dahaarka leh ee Nano-ku-xiran waxay yaraynaysaa qallafsanaanta ilaa Ra0.01μm, hufnaanta shidaalka waxa la hagaajiyay 8%. Injineerkii madaxa ayaa isagoo indho cas leh yiri: "Hal shay oo keliya ayaa badbaadin kara saddex tan oo shidaal ah sannad kasta!"
3. Ka-hortagga wax-soo-saarka gudaha: laga bilaabo "qoorta ku dheggan" ilaa " legdinta gacanta"
Alumina alumina abrasives-ka gudaha waxa ay ahaan jirtay "sheeko murugo leh" - iska caabin liidata, dufcooyin aan xasiloonayn, nano budada agglomeration sida maraq finan, iyo suuqa-dhamaadka sare waxaa monopolized by American iyo Japan shirkadaha13. Laakin mowjadda semiconductor-ka meelaynta ayaa ku qasbay Jedi weerar celis:
Weerar nadiif ah: Warshad ku taal Luoyang ayaa soo saartay foornada arc foornada xakamaynta heerkulka, iyo heerka beddelka wejiga α wuxuu gaadhay 99.95%, nadiifnimaduna waxay la mid tahay Japan Showa Denko.
Metaphysics-ka cabbirka qaybta: Shirkadaha Zhejiang waxay isticmaalaan kala-soocida marawaxadaha AI si ay u xakameeyaan qaybinta cabbirka walxaha gudaha ± 0.1μm. Macaamiisha Kuuriya ayaa daanka tuuray markii ay baarayeen alaabta: "Xogtani way ka saxsan tahay qalabka wax baadha!"
Dib-u-dhalashada qashinka: Saldhigga Shandong ayaa burburiya oo dib u hagaajiya qashinkagiraangiraha shiida, iyo saamiga isku-darka ayaa la dhimay 30%, kharashkana waa la dhimay 40%. Maamulaha aqoon-is-weydaarsiga, Lao Zhou, ayaa qoslay oo canaantay: "Qashinkii lagu tuuri jiray khasaaraha ayaa hadda ka qiimo badan alaabta cusub!"
4.Goobta dagaalka mustaqbalka: saddex isbeddel oo waaweyn ayaa deggan
Xakamaynta heerka Nano: Sheybaarka Hefei wuxuu la yimid tignoolajiyada madow - tignoolajiyada kaydinta lakabka atomiga si loo dhigo "hubka" budada yaryar oo loo xalliyo dhibaatada agglomeration. Cilmi-baaraha ayaa kor u qaaday muunadda oo ku faanay: "Hadda polishing chips waa ka fudud yahay dhumucyada!"
Kacaanka Cagaaran: Warshada Chongqing waxay isticmaashaa nidaamka soo kabashada aashitada wasakhda si ay u yarayso sii daynta 300 oo tan oo qashinka khatarta ah sanad kasta. Dad ka socda Xafiiska Ilaalinta Deegaanka ayaa u yimid inay soo booqdaan waxayna kor u qaadeen suulka: "Waxaad joojinaysaa warshadda nadiifinta bulaacadaha!"
Qalabka wax lagu shiido ee caqliga leh: Warshad ku taal Zhengzhou ayaa ku rakibtay dareeraha cadaadiska giraangiraha shiidada si uu u hagaajiyo cabbirrada wax shiida wakhtiga dhabta ah. Xiao Liu, oo ah farsamayaqaan dhashay sagaashamaadkii, ayaa ku qoray kiiboodhka oo ku faanay: "Hadda hagaajinta cabbirada way ka sahlan tahay ciyaarista ciyaaraha, heerka waxsoosaarkuna wuxuu gaadhay 99.8%!"
