Impuphu ye-silicon carbide eluhlaza: isikhali esiyimfihlo sokuthuthukisa ukusebenza kahle kokupholisha
Ngehora lesibili ekuseni, uLao Zhou waseshabhu lephaneli yangemuva lefoni ephathekayo waphonsa isembozo sengilazi esasisanda kusuka emgqeni wokukhiqiza etafuleni lokuhlola, futhi umsindo wawunjengokucisha iziqhumane. “Bheka! Yiqembu leshumi! Ikhasi eliwolintshi nenkungu. Abahloli be-Apple bazofika kusasa. Ingabe le nto ingalethwa?!” Igazi emehlweni akhe lalibomvu kakhulu kunesibani senkomba emshinini. ULi, owayethule ekhoneni, wasunduza kancane ibhakede lempuphu ecolekileyo eluhlaza okwesibhakabhaka, “Zama lo ‘hlanya oluhlaza’, kuyinto ejabulisa kakhulu ukugaya amathambo aqinile.” Ezinsukwini ezintathu kamuva, iqembu lokuqala lemikhiqizo efanelekile lathuthwa ngendiza ebusuku. ULao Zhou washaya ibhakede likaimpuphu eluhlazafuthi wamomotheka: “Lo mfana omncane othukuthele angasindisa izimpilo ngempela!” Empini yokulwa nokupholisha, okuwumjaho omelene nesikhathi,i-green silicon carbide powder (SiC)umuthi onamandla futhi osebenzayo owelapha ngqo zonke izinhlobo “zokungakwazi ukugaya” kanye “nokungakwazi ukupholisha”.
Impuphu ye-silicon carbide eluhlaza, eyaziwa ngokuthi “ikhabhoni eluhlaza” noma “i-GC"emhlabeni. Akusiso isihlabathi esivamile, kodwa yindoda eqinile "ecwengisisiwe" esithandweni sikagesi se-arc esingaphezu kwama-degree angu-2000 ngezinto ezifana nesihlabathi se-quartz kanye ne-petroleum coke. Inomzimba omuhle: Ubunzima be-Mohs buphakeme njengo-9.2-9.3. Buqinile kancane kune-"i-corundum emhlophe "umzala" futhi ilandela idayimane kuphela. Okumangalisa kakhulu "izingubo zayo eziluhlaza" - amakristalu e-silicon carbide amsulwa kakhulu, anemiphetho ebukhali namakhona, kanye nentukuthelo esheshayo neyolaka. Uma i-corundum emhlophe "iyinkosi yokukhuhla" ezolile, khona-kei-silicon carbide eluhlaza"ingukaputeni wokubhidliza" ephethe i-mace encane, egxile ekuququdeni amathambo aqinile, futhi ukusebenza kwayo kahle kuyamangalisa.
Inani layo lisemoyeni "osheshayo, onembile, nongenasihawu":
1. Ukuluma “amathambo aqinile”: uchwepheshe wazo zonke izinhlobo zokungalaleli
Ingilazi yocingo oluphathwayo (iCorning Gorilla), isibuko sewashi le-sapphire, i-single crystal silicon wafer, i-ceramic substrate… Lezi “zinhlelo zobuso” zemboni yanamuhla zinzima futhi zibuthakathaka kakhulu kunezinye. Izinto ezivamile ezisusa umswakama ngeke zisebenze noma ziphule imiphetho uma kusetshenziswa amandla amaningi kakhulu. Imiphetho ebukhali ye-silicon carbide powder eluhlaza (njengezinsika ezincane ezingenakubalwa ezingeni le-microscopic), kanye nobunzima bayo obuphezulu, kuyivumela ukuthi “isike” ubuso bezinto eziqinile neziphuka kalula ngobukhali nangokuqhubekayo. Ingasusa ngokushesha izinto, esikhundleni “sokulima” njengezisila ukuze ibangele umonakalo omkhulu. Ipholisha isembozo sefoni ephathekayo? Ingasitha “izintaba” ngokushesha ebusweni bengilazi ngaphandle kokubandakanya “izigodi” eziseduze nayo, iphindwe kabili ukusebenza kahle kwayo, kanye nokuthungwa kwekhasi le-orange? Cha!
2. Ukusika “ummese osheshayo”: isikhathi siyimali
Emgqeni wokukhiqiza iphaneli yekristalu yoketshezi ye-TFT-LCD, umzuzwana ngamunye wokugaya nokupholisha umphetho we-substrate yengilazi enkulu kuhlobene nomthamo wokukhiqiza. "Ijubane" lempuphu ye-silicon carbide eluhlaza liqoshwe ezizakhini zayo zofuzo. Izinhlayiya zayo azigcini nje ngokuba ziqinile futhi zibukhali, kodwa futhi ziyazilola ngokumangalisayo - izinhlayiya ezibuthuntu zizoziphula ngaphansi kwengcindezi, zembule imiphetho emisha ebukhali ukuze ziqhubeke nokulwa! Ngokungafani nezinye izinto ezithambile zokuzisusa, ziba "bushelelezi" ngenkathi zigaya, futhi ukusebenza kwazo kwehla. Leli khono "lokuzivuselela" livumela ukuthi libe njengenhlanzi emanzini ezigabeni zokupholisha ezinzima neziphakathi, futhi izinga layo lokususa izinto ngesikhathi ngasinye (MRR) liphambili kakhulu kunezimbangi zayo. Ngemva kokuba ifektri ye-silicon wafer ye-photovoltaic ishintshele ku-slurry ye-silicon carbide eluhlaza enosayizi wezinhlayiya ezithile, ukusebenza kahle kokususwa komphetho we-silicon wafer kwanda ngo-35%, futhi umthamo wokukhiqiza wansuku zonke womugqa owodwa wancishiswa ngamakhulu ezingcezu - ngesikhathi sokufakwa kwejubane, lena yimali yangempela!
3. “Kuhle” ekulinganisweni: ibhalansi ebucayi phakathi kokusebenza kahle nokunemba
Ungacabangi ukuthi “abantu abahlanyayo abaluhlaza"I-" ingenza ngokunganaki kuphela. Ekupholisheni amafasitela e-sapphire ngokunemba, ukukhetha usayizi wezinhlayiya ofanele (njenge-W7, i-W5 noma ngisho nocwebezelayo ngemva kokuhlelwa kahle) kanye nefomula ye-silicon carbide micropowder eluhlaza kukhombisa "ukungaguquguquki okubucayi". Ingasusa ngempumelelo imihuzuko ejulile kanye nezendlalelo zomonakalo ongaphansi komhlaba ezishiywe yinqubo yangaphambilini (njengokugaya idayimane), ukubeka isisekelo esihle nokususa izithiyo zokupholisheni okuhle kwangempela okulandelayo (njengokusebenzisa i-silica sol). Le ndima "yokuxhumanisa eyangaphambilini nelandelayo" ibalulekile. Ngaphandle kwayo ukususa ngempumelelo "ukulimala okunzima", isinyathelo sokupholisheni okuhle esithatha isikhathi sizokwandiswa kakhulu, futhi izinga lokukhiqiza lizoba nzima ukuqinisekisa. Lokhu kufana nokwakha indlu. I-silicon carbide eluhlaza "iyingcweti" ebeka isisekelo ngokushesha nangokulula futhi yakhe izindonga ezithwala umthwalo. Ngaphandle kwayo, "umsebenzi omuhle" wokunamathisela i-foil yegolide kamuva uzoba yize.
4. Ukudlala “ngokugaya amanzi”: ukuzinza kuyindlela yokuhlala isikhathi eside
I-micropowder ye-silicon carbide eluhlaza inezakhiwo zamakhemikhali ezizinzile (ezingenamsebenzi) futhi akulula ukusabela ngoketshezi lokupholisha olusekelwe emanzini noma olusekelwe ku-oyili olusetshenziswa njalo. Kusho ukuthini lokhu? I-slurry inokuqina okuhle futhi akulula ukuyibolisa, ukuyihlalisa noma ukuyihlanganisa! Emgqeni wokupholisha onezinga eliphezulu lokuzenzakalela, ukusebenza kwe-slurry okuzinzile kuyindlela yokuphila. Cabanga ngakho, uma i-abrasive ngezinye izikhathi iwugqinsi futhi ngezinye izikhathi iwugqinsi, futhi izinhlayiya zihlangana ndawonye ukuvimba ipayipi, isivuno kanye nezindleko zokulungisa imishini zizoba zimbi kangakanani?Ikhabhoni Eluhlaza"yenza abantu bangakhathazeki. I-slurry elungiselelwe ingasebenza isikhathi eside noma ngaphezulu, inciphise kakhulu inani lokuvalwa ukuze kulungiswe amapharamitha futhi kuhlanzwe amapayipi. ULao Wu, umphathi wokukhiqiza wefektri yokubeka izinsimbi ze-ceramic enembile, uthe ngemizwa: "Selokhu kwashintshwa i-slurry eluhlaza okwesibhakabhaka ye-silicon carbide, ekugcineni ngingahlala phansi ngiphuze itiye elishisayo ngesikhathi sokuhlolwa kwe-shift yasebusuku. Kwakufana nokucima umlilo!"
Kulesi sikhathi sokuphishekela ukushelela nokusebenza kahle,i-micropowder eluhlaza ye-silicon carbideisebenzise amandla ayo aqinile “obudlova” ukuze iqophe igama layo eliphumelelayo nelinokwethenjelwa ngemuva kwezindawo eziningi ezibushelelezi ezifana nesibuko—akuyona indima emnene, kodwa “isikhali esiyimfihlo” esifanelwe ukuthuthukisa ukusebenza kahle kokupholisha.
