Emafektri amaningi, amanye amapayipi abekezelela buthule izimo zokusebenza ezinzima kakhulu: izinga lokushisa eliphezulu, ukugqwala okunamandla, kanye nokuguguleka okuphezulu. 'Yimithambo yegazi yezimboni' eqinisekisa ukukhiqizwa okuqhubekayo nokuzinzile. Namuhla sizokhuluma ngalowo ovelele kulolu hlobo lwepayipi -ipayipi le-ceramic le-silicon carbide.
Abantu abaningi bacabanga “ngokungaqini” uma bezwa “i-ceramic”. Kodwa izitsha ze-silicon carbide zezimboni ziphishekela “ubulukhuni” kanye “nokuqina” okuphelele. Ubulukhuni bayo buphezulu kakhulu, futhi ukumelana kwayo nokuguguleka kudlula kakhulu okwensimbi nerabha. Ingamelana nokuguguleka koketshezi olusheshayo oluqukethe izinhlayiya eziqinile isikhathi eside; Izakhiwo zamakhemikhali zizinzile kakhulu futhi ingamelana nokuguguleka kwama-asidi aqinile ahlukahlukene, izisekelo eziqinile, nosawoti; Ngesikhathi esifanayo, ingasebenza kahle emazingeni okushisa aphezulu futhi imelane namazinga okushisa afinyelela ku-1350 ℃. Ngaphezu kwalokho, inomoya omuhle wokushisa kanye nobuso obubushelelezi, okusiza ukunciphisa ukumelana nokuhamba kanye nokusetshenziswa kwamandla.
Kalula nje, amashubhu e-silicon carbide ceramic aklanyelwe ukuxazulula izinkinga zokuhamba "ezishisayo, ezirhabaxa, nezigqwalisayo". Ekuthuthweni kwe-slag kanye nodaka ezimbonini ezifana nezezimayini, i-metallurgy, kanye namandla okushisa, kungandisa kakhulu impilo yesevisi yamapayipi futhi kunciphise isikhathi sokungasebenzi sokufakwa esikhundleni; Ekuthuthweni kwemidiya egqwalisayo ezimbonini zamakhemikhali kanye nokuvikelwa kwemvelo, kungaqinisekisa ukusebenza okuzinzile kwesikhathi eside futhi kunciphise ingozi yokuvuza. Nakuba ukutshalwa kwezimali kokuqala kungaba phezulu, izinzuzo zesikhathi eside zibalulekile ngokombono ophelele wokunciphisa ukulungiswa, ukunciphisa ukusetshenziswa kwamandla, kanye nokuqinisekisa ukukhiqizwa.
Ukukhiqizwa kwamashubhu e-silicon carbide ceramic kuwumsebenzi obucayi. Ngokuvamile, i-silicon carbide powder ixutshwa nenani elincane lezithasiselo ukuze kwakhiwe “umzimba oluhlaza” onamandla athile, bese ishiswa ekushiseni okuphezulu ukuze kwenziwe izinto zibe lukhuni futhi zibe nzima. Ngokwezidingo ezahlukene, kuzosetshenziswa izinqubo ezahlukene njengokushiswa kokusabela kanye nokushiswa okungenangcindezi. Ukuze kube lula ukufakwa, amapayipi aqediwe avame ukuhlonyiswa ngezingxenye ezixhumanisayo njenge-flanges zensimbi.
Naphezu kokusebenza kwayo okuphezulu, amashubhu e-silicon carbide ceramic aseyizinto zobumba ezidinga "ukuphathwa kahle" uma zisetshenziswa. Ukufakwa nokuthuthwa kufanele kuphathwe ngokucophelela ukuze kugwenywe umthelela onzima; Qinisekisa ukwesekwa okwanele kanye nesinxephezelo sokwandiswa kokushisa ukuze ugweme imithwalo eyengeziwe ebangelwa ukucindezeleka kwangaphandle noma izinguquko zokushisa; Ngaphambi kokukhetha izinto, kungcono ukuba nonjiniyela ochwepheshe ahlole indawo ethile, izinga lokushisa, kanye nengcindezi ukuze athole ikhambi elifanele kakhulu.
Sekukonke, amashubhu e-silicon carbide ceramic afinyelele izinga eliphezulu "lokuqina" kanye "nokuqina", enikeza izixazululo ezinokwethenjelwa zezimo zokudlulisa ezidinga kakhulu, futhi ngempela "angamaqhawe angabonakali".
