Ukungena emhlabeni wezobuchwepheshe we-green silicon carbide micropowder
Etafuleni laselabhorethri yefekthri e-Zibo, e-Shandong, uchwepheshe u-Lao Li ucosha impushana eluhlaza esimaragidu egcwele ama-tweezers. "Le nto ilingana nemishini emithathu engenisiwe endaweni yethu yokusebenzela." Acimeze amoyizele. Lo mbala we-emerald yi-silicon carbide micropowder eluhlaza eyaziwa ngokuthi "amazinyo ezimboni". Kusukela ekusikeni kwengilazi ye-photovoltaic kuya ekugayweni kwama-chip substrates, le nto engumlingo enosayizi wezinhlayiyana ezingaphansi kwengxenye yekhulu yezinwele ibhala inganekwane yayo enkundleni yempi yokusungula izinto ezintsha zesayensi nezobuchwepheshe.
1. Ikhodi yobuchwepheshe emnyama esihlabathini
Ngingena kuworkshop yokukhiqiza yei-silicon carbide micropowder eluhlaza, okukushayayo akulona uthuli olucatshangelwayo, kodwa impophoma eluhlaza enokukhanya kwensimbi. Lawa ma-powder anesilinganiso sosayizi wezinhlayiyana zama-microns angu-3 kuphela (okulingana nezinhlayiya ze-PM2.5) anobunzima obungu-9.5 esikalini se-Mohs, okwesibili kumadayimane. UMnu. Wang, umqondisi wezobuchwepheshe wenkampani yase-Luoyang, e-Henan, unekhono eliyingqayizivele: bamba i-micropowder encane bese uyifafaza ephepheni le-A4, futhi ungabona isakhiwo sekristalu esinezinhlangothi ezine ngengilazi yokukhulisa. "Amakristalu aphelele angaphezu kuka-98% kuphela angabizwa ngemikhiqizo yekhwalithi ephezulu. Lokhu kuqinile kakhulu kunomncintiswano wonobuhle." Uthe ngesikhathi ekhombisa izithombe ezincane embikweni wokuhlolwa kwekhwalithi.
Kodwa ukuguqula amatshe amatshe abe yingqalabutho yezobuchwepheshe, amandla emvelo ewodwa akwanele. “Ubuchwepheshe bokugaywa kweziqondiso” elabhorethri yesiFundazwe saseJiangsu eyagqekeza ngonyaka odlule bukhulise ukusebenza kahle kokusika impuphu encane ngama-40%. Balawula amandla kazibuthe wenkundla ye-crusher ukuphoqa ikristalu ukuthi iqhekeke ngendiza ethile yekristalu. Njengokuthi "ukudubula inkomo inqamule intaba" kumanoveli obuciko bokulwa, ukuchotshozwa kwemishini okubonakala kunobudlova empeleni kufihla ukulawulwa okunembile kweleveli. Ngemuva kokuthi lobu buchwepheshe buqaliswe, izinga lokukhiqiza lokusika ingilazi ye-photovoltaic lenyuke lisuka ku-82% laya ku-96%.
2. Uguquko olungabonakali endaweni yokukhiqiza
Esizindeni sokukhiqiza e-Xingtai, e-Hebei, isithando somlilo esinezitezi ezinhlanu sikhafula amalangabi acwazimulayo. Ngesikhathi izinga lokushisa lomlilo libonisa u-2300 ℃, uchwepheshe u-Xiao Chen ucindezele inkinobho yokuphakelayo. "Okwamanje, ukufafaza isihlabathi se-quartz kufana nokulawula ukushisa lapho upheka." Wakhomba ijika le-jumping spectrum ku-monitor screen wachaza. Isistimu yokulawula ehlakaniphile yanamuhla ingahlaziya okuqukethwe kwezinto ezingu-17 esithandweni ngesikhathi sangempela futhi ilungise ngokuzenzakalelayo isilinganiso se-carbon-silicon. Ngonyaka odlule, lolu hlelo luvumele izinga lomkhiqizo wabo we-premium ukuthi linqamule uphawu lwama-90%, futhi inqwaba yemfucuza yehliswa ngokuqondile ngokuphindwe kabili kokuthathu.
Eshabhu yokugreda, umshini wokuhlela ukugeleza komoya ophehlwayo onobubanzi obungamamitha ayisishiyagalombili wenza “igolide yokugezela olwandle lwesihlabathi”. “Indlela yokuhlunga enezinhlangothi ezintathu” eyakhiwe inkampani yakwaFujian ihlukanisa imakrofoni ibe amamaki ayi-12 ngokulungisa isivinini sokugeleza komoya, izinga lokushisa, umswakama, kanye nokushajwa. Umkhiqizo omuhle kakhulu we-mesh we-8000 uthengiswa ngama-yuan angaphezu kuka-200 ngegremu, eyaziwa ngokuthi "i-Hermes in powder". Umqondisi weshabhu uLao Zhang wancokola ngesampula esanda kuphuma kulayini: “Uma lokhu kuchitheka, kuzoba buhlungu kakhulu kunokuchitha imali.”
3. Impi yesikhathi esizayo yokukhiqiza okuhlakaniphile okuluhlaza
Uma sibheka emuva ezimpambanweni zobuchwepheshe nezimboni, indaba ye-silicon carbide micropowder ifana nomlando wokuziphendukela kwemvelo wezwe elincanyana. Kusukela esihlabathini namatshe amatshe kuya ezintweni eziphambili, kusukela ezindaweni zokukhiqiza kuya ezinkanyezini nolwandle, lokhu kuthinta okuluhlaza kungena kuma-capillaries embonini yesimanje. Njengoba umqondisi wocwaningo nentuthuko we-BOE esho: “Ngezinye izikhathi akuzona imidondoshiya eshintsha umhlaba, kodwa izinhlayiya ezincane ongaziboni.” Njengoba izinkampani ezengeziwe ziqala ukungena kulo mhlaba wezinto ezincane kakhulu, mhlawumbe imbewu yenguquko elandelayo yezobuchwepheshe ifihliwe kumpushana oluhlaza ocwebezelayo phambi kwamehlo ethu.
