Incazelo

Isigubhu sokugaya i-silicon carbide sithatha inqubo yokubumba yokucindezelwa kwe-isostatic, ukuminyana okungu-3.09g/cm3, umkhawulo ongu-φ950mm, ubulukhuni be-Vickers 2550HV.

Ukusetshenziswa komgqomo wokugaya we-Silicon carbide ceramic embonini ye-metallurgy namakhemikhali Kusukela ngeminyaka yawo-1970s kuya ekuqaleni kwawo-1990, umphongolo we-silicon carbide ceramic wokugaya unokumelana okuphezulu nensimbi encibilikisiwe, i-slag, ukumelana nokugqwala kwensimbi ye-alkali, futhi inokuhanjiswa okuphezulu kwe-thermal kanye nempahla.Iziqhumiso ezinkulu ezingama-65 emhlabeni zisebenzisa i-silicon nitride ne-silicon carbide njengeziko, ukuze isikhathi sokuncibilikisa i-aluminium, ithusi, i-zinc sifinyelele ku-2096-40%.Izinto ezahlukahlukene ze-SIC nazo zisetshenziswa njengama-linings noma ama-crucible.Ezimbonini zamakhemikhali nezensimbi, izishintshisi zokushisa ze-ceramic zivame ukusetshenziselwa ukushisa kuqala amagesi ahlukahlukene noma uketshezi ukuze kusetshenziswe ngokugcwele ukushisa kwegesi yokukhipha izithando zokushisa ezihlukahlukene.

Inzuzo yokugaya i-silicon carbide emgqonyeni

(1) Amandla aphezulu emishini, kuhle njengalokhu
Amandla aphezulu emishini angavimbela ngokuphumelelayo ukuguqulwa kwezinto ezibonakalayo, okubaluleke kakhulu.I-silicon carbide inamandla amakhulu emishini kune-corundum.Isibonelo, amandla acindezelayo e-silicon carbide angama-224MPa, kanti awe-corundum angama-75.7MPa kuphela.Amandla okugoba e-silicon carbide ngu-15.5MPa, kanti awe-corundum ngu-8.72MPa.

(2) Ukuqina okuphezulu nokumelana nokugqoka
Ukuqina kwe-silicon carbide kuphezulu kakhulu, ngokokuqina kwe-notch ye-Mohs phakathi kuka-9.2 ~ 9.6, okwesibili ngemuva kwedayimane ne-boron carbide, kuphakeme kune-corundum, ngakho-ke ekugayeni okuvamile nokuzamazama phakathi kwezingcono kakhulu.Uma kuqhathaniswa nensimbi yensimbi, akukhona nje kuphela ubulukhuni obuphezulu, kodwa futhi esimweni sokungenwa kwe-lubricating ye-friction coefficient incane, ukungqubuzana okuncane, ukuqina kwendawo kuncane, ukumelana nokugqoka kuhle.Ngaphezu impahla yangaphandle has a strong umthelela ukumelana, ngcono surface bearing umthamo.

(3) Ukumelana nokugqwala
I-silicon carbide ngenxa yendawo yayo yokuncibilika (izinga lokushisa lokubola), inertia yamakhemikhali kanye nokumelana nokushaqeka okushisayo kuphezulu, ingasetshenziselwa imikhiqizo ehlukahlukene ye-silicon carbide ceramic, njengemikhiqizo yobumba amathuluzi okugaya isithando somlilo, ipuleti losilingi kanye nesaga, i-zinc encibilikisa mpo yezimboni. Isithando somlilo esine-silicon carbide, i-aluminium electrolytic cell lining, i-crucible, into encane yomlilo.

Isicelo sokumelana nokugqwala

I-1, izingxenye ezishelelayo (uphawu lwemishini, i-chemical pump bearing, shaft)
2, izesekeli ze-crusher (i-classifier, isigayo somoya, isigayo sesihlabathi)
3.Izingxenye zemishini yokukhiqiza iSemiconductor (iplathifomu ye-XY, ithreyi ye-MOCVD, indandatho yokugxila, i-wafer chuck)
4. Izingxenye zomshini wokubumba (izingxenye zomshini wokubumba amalensi ekhamera)
Izingxenye ezi-5 ezimelana nokushisa (imbobo yokushisa, izingxenye zomshini wokuhlola izinga lokushisa eliphezulu, insimbi encibilikisiwe)
6. Izingxenye ezingagugi (umbhobho womshini oqhuma isihlabathi, insingo yomshini oqhumayo ocwebezelayo, ipuleti lokuvikela amapayipi, indandatho yomhlahlandlela wokudoba)
