Ezindaweni zokuhlukanisa uketshezi oluqinile ezimbonini ezifana nezezimayini, amakhemikhali, kanye nokuvikelwa kwemvelo, ukuba khona kweziphepho ze-silicon carbide kungabonakala njalo. Kufana "nomshini wokuhlunga" ophumelelayo ongahlukanisa ngokushesha izinhlayiya eziqinile koketshezi ngengxube, futhi umongo wokufeza lokhu kuhlukaniswa okunembile awukwazi ukuhlukaniswa ngaphandle kwengxenye enganakwa kalula - ipayipi elichichimayo.
Abantu abaningi, lapho beqala ukubonaisiphepho se-silicon carbide,bavame ukugxila ekugxileni kwabo esilinda esiyinhloko esiqinile, kodwa banganaki “ipayipi elincane” elisuka phezulu. Kodwa empeleni, ipayipi elichichimayo “liyi-conductor” yalo lonke uhlelo lokuhlukanisa, futhi ukwakheka kwalo nesimo salo kunquma ngqo ikhwalithi yomphumela wokuhlukanisa.
Ngokombono womgomo wokusebenza, isiphepho se-silicon carbide sithembele emandleni e-centrifugal akhiqizwa ukujikeleza kwesivinini esikhulu ukuze kufezwe ukuhlukana: ngemva kokuba uketshezi oluxubile lungene lusuka echwebeni lokuphakelayo, lujikeleza ngesivinini esikhulu ngaphakathi kwesilinda, bese izinhlayiya eziqinile ezinobukhulu obuphezulu ziphonswa odongeni lwesilinda bese zikhishwa echwebeni lokugeleza elingezansi; Uketshezi olunobukhulu obuphansi (noma izinhlayiya ezincane) zizohlangana enkabeni yokujikeleza, zakha "ikholomu yomoya" egcina igeleza ngepayipi lokugeleza phezulu. Kuleli qophelo, indima yepayipi lokugeleza iba yinto evelele - akuyona nje indawo yokukhipha "izinto zesigaba sokukhanya", kodwa futhi iqinisa insimu yokugeleza ngaphakathi kwesiphepho sonke ngokulawula izinga lokugeleza kanye nokucindezela.
Kungani kudingeka ukusebenzisa izinto ze-silicon carbide ukwenza amapayipi okugcwala? Lokhu kuhlobene eduze nendawo yayo yokusebenza. Ngesikhathi senqubo yokuhlukanisa, uketshezi olugeleza ngepayipi lokugcwala luvame ukuba nezinhlayiya ezincane, futhi ukuhlanzwa isikhathi eside kungabangela ukuguguleka kwepayipi; Ngesikhathi esifanayo, ezinye izinto zezimboni nazo zinezakhiwo ze-acidic noma ze-alkaline, futhi amapayipi ensimbi avamile aguguleka kalula. Izinto ze-silicon carbide zixazulula ngokunembile lezi zinkinga ezimbili ezinkulu: ubulukhuni bazo bulandela idayimane kuphela, ukumelana kwazo nokuguguleka kuphindwe kaningi kunokwensimbi evamile, futhi zingamelana nokuguguleka kwezinhlayiya isikhathi eside; Ngesikhathi esifanayo, zinokumelana nokugqwala kwe-acid ne-alkali okunamandla kakhulu, futhi zingagcina ukusebenza okuzinzile ngisho nangaphansi kwezimo zokushisa eziphakeme kanye nokugqwala okunamandla, kwandise kakhulu impilo yenkonzo yemishini.
Omunye umuntu angase abuze: Uma nje ipayipi lokugcwala lingonakali, ingabe akudingekile ukulinakekela? Empeleni, akunjalo. Ukunemba kokufakwa kwepayipi lokugcwala kungathinta nomphumela wokuhlukanisa. Isibonelo, uma ukujula kwepayipi lokugcwala elifakwe emzimbeni oyinhloko wesiphepho kuphansi kakhulu, kungabangela ukuthi ezinye izinhlayiya eziqinile zithwalwe ngephutha ziye oketshezini lokugcwala, okuholela "ekuhambeni okuqinile"; Uma lifakwe ngokujulile kakhulu, lizokwandisa ukumelana kokugeleza koketshezi futhi linciphise ukusebenza kahle kokuhlukaniswa. Ngaphezu kwalokho, uma kunokungcola okuningi okunamathiselwe odongeni lwangaphakathi lwepayipi lokugcwala ngesikhathi sokusetshenziswa kwansuku zonke, kuzonciphisa isiteshi sokugeleza futhi kuthinte izinga lokugeleza kanye nokunemba kokuhlukaniswa. Ngakho-ke, ukuhlanza nokuhlola njalo kubalulekile.
Namuhla, njengoba isidingo sokwanda kokusebenza kahle kokuhlukaniswa kanye nokuvikelwa kwemvelo embonini, ukwakheka kwamapayipi okugcwala kwe-silicon carbide nakho kuhlale kuthuthukiswa. Isibonelo, ngokulungisa ukuma komlomo wepayipi nokwenza ngcono usayizi wobubanzi bangaphakathi, kunciphisa kakhulu ukumelana noketshezi; Abanye abakhiqizi benza nokwelashwa okukhethekile kokupholisha emlonyeni wepayipi ukuze kuncishiswe ukunamathela kokungcola futhi kwenze inqubo yokuhlukaniswa ibe nokuzinza futhi isebenze kahle.
Ipayipi elibonakala lilula le-silicon carbide overflow lifihla inhlanganisela ehlakaniphile yesayensi yezinto zokwakha kanye ne-fluid mechanics ngemuva kwalo. Lithatha "umthwalo wemfanelo omkhulu" "ngomzimba walo omncane", libe yisixhumanisi esibalulekile ekuqinisekiseni ukusebenza okuzinzile kweziphepho ze-silicon carbide kanye nokuthuthukisa ikhwalithi yokuhlukaniswa. Esikhathini esizayo, ngokuthuthuka okuqhubekayo kobuchwepheshe bezinto ze-silicon carbide, le ndoda eyinhloko 'izodlala indima ebalulekile emikhakheni eminingi, inikele ekuthuthukisweni okusebenzayo nokuluhlaza komkhiqizo wezimboni.
