I-Green Silicon Carbide Micropowder: Uphawu Olusha Lwezinto Ezisebenza Kahle Kakhulu, Ezisindisa Amandla
I. Kuyini Ngempela? Kungani Kubizwa ngokuthi “i-Hardcore”?
Okokuqala, ake siqonde ukuthi yinii-micropowder eluhlaza ye-silicon carbideiyi. Cabanga ngayo njengohlobo "lwedayimane lokwenziwa." Nakuba ingaqinile kangako kunedayimane langempela, ngokungangabazeki iyisithako esiphezulu. Ihlungiwe esithandweni sokumelana nokushisa okuphezulu kuma-degree Celsius angaphezu kuka-2,000 kusetshenziswa isihlabathi se-quartz, i-petroleum coke, nezinye izinto zokusetshenziswa, okwenza ithole umbala wayo oluhlaza ohlukile.
Uhlobo lwayo "oluqinile" lubonakala kakhulu ezicini ezintathu:
Ukuqina Okuphezulu Nomphetho Obukhali: Ukuqina kwayo kwe-Mohs kufinyelela ku-9.2, okwesibili ngemuva kwedayimane. Lokhu kusho ukuthi lapho isika futhi isigaya, isebenza njengezinyo elincane, elibukhali, "eligaya" kalula ezintweni eziqinile nezibuthakathaka njenge-photovoltaic silicon wafers, ingilazi ye-sapphire, namakristalu e-piezoelectric.
Ukuqina Okukhulu, Ukukhetha Ukuphuka Kunokuba Ukugoba: Ukuqina kukodwa akwanele; kudinga nokuqina. Ezinye izinto ziyaphuka kakhulu futhi ziyaqhekeka zibe yizimpushana ezincane uma zicindezelwa, okwenza zingabi usizo. I-micropowder eluhlaza ye-silicon carbide inamandla aphezulu ngenkathi igcina ukuqina okuhle kakhulu. Igcina isimo sayo ngaphansi kwengcindezi enkulu, isebenzisa amandla ngempumelelo endaweni yokusebenza ngaphandle kokuphuka.
Kuzinzile futhi kusebenza kanzima: Emazingeni okushisa asekamelweni, ayisebenzi kahle nanoma yimaphi ama-asidi noma izisekelo, okwenza kube yinto esebenza kanzima. Lokhu kusho ukuthi ngesikhathi senqubo yokusika, igwema ukusabela kwamakhemikhali okungafuneki lapho izinto zicutshungulwa, okuqinisekisa ubumsulwa bezinto. Lokhu kubalulekile embonini ye-photovoltaic kanye ne-semiconductor, lapho ubumsulwa bubaluleke kakhulu khona.
II. Ukusebenza kahle kakhulu nokonga amandla—akuzona nje iziqubulo ezingenalutho
Ukufinyelela ephuzwini: Kungani kubizwa ngokuthi “isilinganiso esisha”? Lokhu kusebenza kahle kakhulu nokonga amandla kuboniswa kanjani ngokuqondile? Ake sinciphise udoti bese sibonisa izimo ezithile ezisebenzayo.
Isimo 1: “Abasiki Abaqondile” Be-Photovoltaic Silicon Wafers
Lao Zhang, ujwayelene kakhulu nalokhu.Izinto ze-siliconKubiza kakhulu kulezi zinsuku. Ukuyisika ibe ncane kuveza ama-wafer amaningi, kunciphisa izindleko. Kodwa-ke, ama-wafer e-silicon anciphile asengozini enkulu yokuphuka, okudinga amazinga aphezulu obuchwepheshe bokusika kanye ne-abrasives. I-micropowder ye-silicon carbide eluhlaza, enesimo sayo sezinhlayiya ezifanayo kanye nemiphetho ebukhali, ikhiqiza amandla okusika azinzile futhi afanayo ngesikhathi senqubo yokusika. Umphumela:
Ukusebenza kahle kokusika: Ama-wafer amaningi anganqunywa ngesikhathi esifanayo, noma isivinini sokusika singandiswa.
Ikhwalithi ephezulu kakhulu yobuso: Ingqimba yomonakalo wobuso yama-wafer e-silicon asikiwe incane kakhulu, kanti i-TTV (ukwehluka kobukhulu obuphelele) iphansi, okuholela ekwandeni okusheshayo kwesivuno.
Ukulahleka kwezinto eziphansi: Ukusika okunembile kuholela ekulahlekelweni okuncane kwe-kerf, kunciphisa ukuchithwa kwezinto ezibizayo ze-silicon. Ngokutshalwa kwezimali okuvame ukwedlula amakhulu ezigidi zama-yuan, lokhu konga kukhulu.
Isimo 2: “Umdlali okhuthazelayo” wokucubungula i-sapphire
Iningi lekhava lekhamera yefoni yakho kanye nengilazi yewashi ephezulu zenziwe nge-sapphire. I-sapphire inzima kakhulu kunengilazi futhi kuyinselele kakhulu ukuyicubungula. Ukusebenzisa izinto ezivamile zokuzisusa kungayithuntubeza ngemva kwesikhathi esifushane, kunciphisa kakhulu ukusebenza kahle. Kodwa-ke, i-micropowder eluhlaza ye-silicon carbide, ngenxa yokumelana kwayo okuhle kakhulu nokuguguleka, igcina umkhawulo obukhali isikhathi eside, yandisa impilo yayo yesevisi. Lokhu kusho ukuthi:
Imvamisa yezinguquko ezirhabaxa iyancipha, isikhathi sokungasebenzi siyafinyezwa, futhi ukusebenza kahle kokukhiqiza kuyathuthuka.
Izindleko zokucubungula zizonke zincishisiwe. Nakuba intengo ngethani ingaba phezulu, ukusebenza kahle okwandisiwe kanye nezinto ezisetshenziswayo ezincishisiwe empeleni kunciphisa izindleko eziphelele. Lokhu kuyiqiniso "ukonga amandla."
Isimo 3: Ukwanda Kwaze Kwaba Yizwe Elibanzi
Amakhono ayo adlula lokhu. Ukuyifaka ezintweni ezithuthukisiwe eziphikisayo kungandisa impilo yama-oven futhi kuthuthukise ukufudumala, konge amandla ngempumelelo ezithandweni zezimboni ezisebenzisa amandla amaningi. Ezintweni ezihlanganisiwe, njengokuqinisa, kwenza izingxenye zingagugi futhi zibe namandla, kwandise imijikelezo yokugcinwa kwemishini—futhi kuyindlela efihliwe yokonga amandla. Ngisho nasembonini yezindiza, ibaluleke kakhulu ekugayweni ngokunembile kwezingxenye ezithile ezikhethekile ze-ceramic.
III. Indlela Engaphambili: Enhle Kakhulu, Efana Kakhulu, Ehlakaniphile Kakhulu
Yiqiniso, i-micropowder eluhlaza ye-silicon carbide ayiphelele. Ukuze kuqinisekiswe lokhu “kubhekisiswa okusha,” abakhiqizi bethu kumele basebenze ngenkuthalo ezindaweni eziningana:
Ukulungiswa okuqhubekayo kosayizi wezinhlayiya: Izimboni ezingezansi zifuna ukunemba okuphezulu kakhulu. Sidinga ukukhiqiza ama-micropowders anokusatshalaliswa kosayizi wezinhlayiya okugxile kakhulu kanye nesimo sezinhlayiya esivamile (i-isomorphism engcono). Lokhu kufana neqembu lamasosha elihamba ndawonye futhi lihamba ngendlela ehlangene ukuze kufezwe kahle kakhulu empini. Okuqukethwe kwezinhlayiya ezinkulu nezincane (okuthiwa “ziqinile” futhi “zincane”) kumele kulawulwe ngokuqinile; ngaphandle kwalokho, ukusika kuzoholela ekuklwebhekeni emsebenzini kanye nokusebenza kahle okuncishisiwe.
Ubuciko bokuguqulwa kobuso: Ukuguqulwa kobusoizinhlayiya ezincane ze-powderkuwumsebenzi wobuchwepheshe obuphezulu. Isibonelo, ukuthuthukisa ukuhambisana kwazo noketshezi lokusika kanye nezihlanganisi ze-resin kungathuthukisa kakhulu ukusebenza kahle kokusika kanye nokusebenza komkhiqizo. Kufana nokugcoba inkemba nge-oyili—ayigcini nje ngokulola umkhawulo wayo kodwa futhi yandisa ukuqina kwayo.
Ukwakha Imvelo Yenqubo Yokukhiqiza: Nakuba iyinto esindisa amandla, ingabe inqubo yayo yokukhiqiza ingaba wusizo kakhulu futhi inobungani nemvelo? Isibonelo, ukusetshenziswa kwamandla ezithandweni zokuncibilikisa, ukuqoqwa kothuli ngesikhathi sokuchoboza nokuhlola, kanye nokuvuselelwa kwamanzi—zonke izindawo ezidinga ukuthuthukiswa okuqhubekayo kanye nokuphindaphinda embonini yethu. Silwela ukudala izinto eziluhlaza kuyo yonke impilo yazo.
Kulabo bethu embonini yezinto zokwakha, indaba ye-green silicon carbide micropowder isanda kuqala. Ukuyenza ibe ngcono, ibe nemininingwane eminingi, futhi ihlakaniphe kakhulu kungumnikelo wethu obaluleke kakhulu ekuqhubekiseleni phambili ukukhiqizwa kwekhwalithi ephezulu eShayina ekusebenzeni kahle nasekulondolozweni kwamandla.
