Ukungena ezweni lobuchwepheshe le-green silicon carbide micropowder
Etafuleni lelebhu efektri eZibo, eShandong, uchwepheshe uLao Li uqoqa inqwaba yempuphu eluhlaza ye-emerald enama-tweezers. “Le nto ilingana nemishini emithathu engenisiwe eshabhu lethu.” Wabheka phansi wamomotheka. Lo mbala we-emerald uyi-micropowder eluhlaza ye-silicon carbide eyaziwa ngokuthi “amazinyo ezimboni”. Kusukela ekusikeni ingilazi ye-photovoltaic kuya ekugayweni kwezingxenye ze-chip, le nto yomlingo enobukhulu bezinhlayiya ezingaphansi kwengxenye eyodwa kweziyikhulu yezinwele ibhala inganekwane yayo empini yokusungula izinto ezintsha kwesayensi nobuchwepheshe.
1. Ikhodi yobuchwepheshe obumnyama esihlabathini
Ngingena eshabhu lokukhiqiza le-i-micropowder eluhlaza ye-silicon carbide, okukushayayo akulona uthuli olucatshangwayo, kodwa impophoma eluhlaza enokukhanya kwensimbi. Lawa ma-powder anesilinganiso sobukhulu bezinhlayiya ezingama-micron angu-3 kuphela (okulingana nezinhlayiya ze-PM2.5) anobunzima obungu-9.5 esikalini se-Mohs, olandela amadayimane kuphela. UMnu. Wang, umqondisi wezobuchwepheshe wenkampani eLuoyang, eHenan, unekhono eliyingqayizivele: thatha i-micropowder encane bese uyifafaza ephepheni le-A4, bese ubona isakhiwo sekristalu esivamile esinama-hexagonal ngengilazi ekhulisayo. “Amakristalu kuphela aphelele angaphezu kuka-98% angabizwa ngokuthi imikhiqizo yekhwalithi ephezulu. Lokhu kuqinile kakhulu kunomncintiswano wobuhle.” Esho ngenkathi ebonisa izithombe ezincane embikweni wokuhlolwa kwekhwalithi.
Kodwa ukuguqula amatshe abe yiphayona lobuchwepheshe, isipho semvelo sodwa akwanele. "Ubuchwepheshe bokuchoboza obuqondisiwe" obwaqalwa yilabhorethri eSifundazweni saseJiangsu ngonyaka odlule bandise ukusebenza kahle kokusika i-micro-powder ngo-40%. Balawula amandla ensimu kagesi ye-crusher ukuze baphoqe i-crystal ukuba iqhekeze endizeni ethile yekristalu. Njengokuthi "ukudubula inkomo ngaphesheya kwentaba" kumanoveli obuciko bokulwa, ukuchoboza okubonakala kunobudlova kwemishini empeleni kufihla ukulawulwa okunembile kwezinga lama-molecule. Ngemva kokuba lobu buchwepheshe buqaliswe, izinga lokukhiqiza lokusika ingilazi ye-photovoltaic lakhuphuka ngqo lisuka ku-82% laya ku-96%.
2. Uguquko olungabonakali endaweni yokukhiqiza
Esisekelweni sokukhiqiza eXingtai, eHebei, isithando somlilo esinezitezi ezinhlanu sikhipha amalangabi acwebezelayo. Ngesikhathi izinga lokushisa lesithando libonisa u-2300℃, uchwepheshe uXiao Chen wacindezela inkinobho yokuphakelayo ngokuzimisela. “Ngalesi sikhathi, ukufafaza isihlabathi se-quartz kufana nokulawula ukushisa lapho upheka.” Wakhomba ijika le-spectrum eligxumayo esikrinini sokuqapha wabe esechaza. Uhlelo lokulawula oluhlakaniphile lwanamuhla lungahlaziya okuqukethwe kwezinto ezingu-17 esithandweni ngesikhathi sangempela futhi lulungise ngokuzenzakalelayo isilinganiso se-carbon-silicon. Ngonyaka odlule, lolu hlelo lwavumela izinga lomkhiqizo wabo we-premium ukuthi lidlule ku-90%, futhi inqwaba yemfucuza yehliswa ngqo ngamathathu amabili.
Eshabhu lokuhlola, umshini wokuhlunga umoya we-turbine onobubanzi obungamamitha ayisishiyagalombili wenza “i-gold panning olwandle lwesihlabathi”. “Indlela yokuhlunga enezinga ezintathu enezilinganiso ezine” eyathuthukiswa yibhizinisi laseFujian ihlukanisa i-micropowder ibe yizigaba eziyi-12 ngokulungisa isivinini sokugeleza komoya, izinga lokushisa, umswakama, kanye nokushaja. Umkhiqizo we-mesh ongu-8000 omuhle kakhulu uthengiswa ngama-yuan angaphezu kwama-200 ngegremu, owaziwa ngokuthi “i-Hermes in powder”. Umqondisi weshabhu uLao Zhang wahlekisa ngesampula eyayisanda kuphuma emgqeni: “Uma lokhu kuchitheka, kuzoba buhlungu kakhulu kunokuchitha imali.”
3. Impi yesikhathi esizayo yokukhiqiza okuhlakaniphile okuluhlaza
Uma sibheka emuva ekuhlanganeni kobuchwepheshe kanye nezimboni, indaba ye-green silicon carbide micropowder ifana nomlando wokuziphendukela kwemvelo womhlaba omncane. Kusukela esihlabathini nasematsheni kuya ezintweni ezisezingeni eliphezulu, kusukela ezindaweni zokukhiqiza kuya ezinkanyezini nasolwandle, lokhu kuthinta okuluhlaza kungena ema-capillaries embonini yanamuhla. Njengoba umqondisi wocwaningo nentuthuko we-BOE eshilo: “Ngezinye izikhathi akuzona iziqhwaga ezishintsha umhlaba, kodwa izinhlayiya ezincane ongaziboni.” Njengoba izinkampani eziningi ziqala ukungena kulo mhlaba omncane, mhlawumbe imbewu yenguquko elandelayo yezobuchwepheshe ifihliwe kumpuphu oluhlaza ocwebezelayo phambi kwamehlo ethu.
