Iyini indima ye-graphitized petroleum coke embonini yokuncibilikisa njenge-silicon yezimboni kanye ne-silicon carbide?

Indima ye-Graphitized Petroleum Coke Ezimbonini Zokuncibilikisa ze-Industrial Silicon kanye ne-Silicon Carbide

I. Indima Ekuncibilikiseni I-Silicon Yezimboni

1. Umsebenzi We-ejenti Yokunciphisa Umongo
I-graphitized petroleum coke ingenye yezinto eziyinhloko zokunciphisa i-carbonaceous ekukhiqizweni kwe-silicon yezimboni. Okuqukethwe kwayo okuphezulu kwe-carbon (90%-97%) kanye nezici zomlotha ophansi kwenza kube yinto eluhlaza ebalulekile yokuhlinzeka nge-carbon edingekayo ukuze kusebenze. Ngesikhathi sokuncibilikisa i-arc furnace, i-petroleum coke yenza kube lula ukuguqulwa kwe-silica (SiO₂) ibe yi-silicon yezimboni ngokusebenzisa ukusabela kokunciphisa ama-carbohydrate. Ngaphezu kwalokho, ukuhanjiswa kwayo kagesi kusiza ukulawula ukumelana kweshaja ye-furnace, ukulawula ukujula kokufakwa kwe-electrode kanye nokwenza ngcono ukusebenza kwe-arc furnace ye-electric.

2. Ukuthuthukisa Ukusebenza Kokushaja Kwesithando Somlilo

• Ukulungiswa Kokumelana: Ukuqhuba kukagesi kwe-petroleum coke kuthonya ukumelana kweshaja yesithando somlilo. Ngokulungisa umthamo wayo kanye nosayizi wezinhlayiya, ukusebenza kahle kokushisa kwesithando somlilo se-arc kagesi kungathuthukiswa, kuncishiswe ukusetshenziswa kwamandla.
• Ukuthuthukiswa Kokuvunyelwa ...
• Ukwengezwa Komsebenzi Wamakhemikhali: I-petroleum coke ikhombisa izakhiwo zokunciphisa ezibuthakathaka futhi ivame ukusetshenziswa kanye namalahle e-silicon aphansi noma amalahle ukuqinisekisa ukuqhubeka okushelelayo kokusabela kokunciphisa.

3. Ibhalansi Phakathi Kwekhwalithi Nezindleko

• Ukukhiqizwa kwe-Silicon Esezingeni Eliphezulu: Okuqukethwe komlotha okuphansi kwe-petroleum coke kwenza ifaneleke ukukhiqiza i-silicon yezimboni ehlanzekile kakhulu. Kodwa-ke, isulfure, i-vanadium, i-nickel, nokunye ukungcola kumele kulawulwe, ikakhulukazi ekukhiqizweni kwe-organosilicon, lapho izilinganiso ze-petroleum coke zinqunyelwe ukuvimbela ubuthi be-catalyst.
• Izinzuzo Zezomnotho: Uma kuqhathaniswa namalahle, i-petroleum coke itholakala kabanzi, intengo yayo izinzile, futhi ayithinteki kakhulu yizinqubomgomo zemvelo, okwenza kube yinto ekhethwayo yokunciphisa umkhiqizo omkhulu.

II. Indima Ekuncibilikiseni I-Silicon Carbide

1. Ukuhlinzekwa Komthombo Wekhabhoni
Ukukhiqizwa kwe-silicon carbide (SiC) kudinga umthombo wekhabhoni ohlanzekile kakhulu. Ngemva kokufakwa kwe-calcination, i-graphitized petroleum coke ibonisa okuqukethwe okunciphile okuguquguqukayo kanye ne-graphitization ethuthukisiwe, okuhlinzeka ngomthombo wekhabhoni ozinzile okhuthaza ukusabela kwesigaba esiqinile phakathi kwe-silicon nekhabhoni ukukhiqiza i-silicon carbide ehlanzekile kakhulu.

2. Izicelo Ezintweni Ezingasebenzi
I-petroleum coke ingasetshenziswa ngqo ukukhiqiza ama-abrasives e-silicon carbide (isb., amasondo okugaya, i-sandpaper). Ubulukhuni bayo obuphezulu kanye nokumelana nokuguguleka kwenza kube yinto ebalulekile yokusetshenziswa kwensimbi, ukupholisha i-ceramic, nezinye izinhlelo zokusebenza.

3. Ukuthuthukisa Inqubo

• Ukwelashwa Kokubala: Ukubala i-coke kaphethiloli eluhlaza ku-1300°C kunciphisa okuqukethwe yi-hydrogen futhi kuthuthukisa i-graphitization, kuthuthukisa ukuhanjiswa kukagesi kanye nokumelana nokushisa kwemikhiqizo ye-silicon carbide.
• Ukulawula Usayizi Wezinhlayiyana: Ukulungisa usayizi wezinhlayiyana ze-petroleum coke kuthuthukisa inqubo yokwenza i-crystallization ye-silicon carbide, kuthuthukisa ukufana komkhiqizo.

III. Indima Ephelele kanye Nenani Lemboni

1. Ukusebenza Kahle Kokuncibilikisa Okuthuthukisiwe
Ukuqhuba kukagesi kanye nokuzinza kwamakhemikhali kwe-graphitized petroleum coke kunciphisa ukusetshenziswa kwamandla ezithandweni zikagesi ze-arc, kufinyeze imijikelezo yokuncibilikisa, futhi kuthuthukise ukusebenza kahle kokukhiqiza. Isibonelo, ekukhiqizweni kwe-silicon yezimboni, ukuxuba kahle i-petroleum coke kunganciphisa ukusetshenziswa kwamandla ngo-5%-10%.

2. Ukuqinisekiswa Kwekhwalithi
Ukulawula amazinga esibabule, umlotha, kanye nokungcola ku-petroleum coke kunciphisa ukufakwa okungeyona insimbi ku-silicon yezimboni futhi kuthuthukisa ubumsulwa be-silicon carbide, okuhlangabezana nezidingo zokukhiqiza okuphezulu (isb., i-silicon carbide yezinga le-semiconductor).

3. Ukuthuthukisa Izimboni
Njengoba imboni yokuncibilikisa iqhubekela phambili emisebenzini emikhulu nehlakaniphile, ubumsulwa obukhulu kanye nokucwebezela kwe-graphitized petroleum coke kusekela ukukhiqizwa kwama-electrode paste asebenza kahle kakhulu kanye nama-electrode amakhulu e-carbon, okukhuthaza ukuthuthukiswa kobuchwepheshe kulo lonke umkhakha.
