Izinhlobo ze-Reaction Bonded Silicone Carbide (RBSiC/SiSiC)

Izinhlobo ZokusabelaI-Silicone Carbide Ehlanganisiwe (RBSiC/SiSiC)

Njengamanje, kunenani elikhulu labakhiqizi abazohlinzeka ngemikhiqizo ye-Reaction Bonded SIC ezimbonini ezahlukahlukene. I-Shandong Zhongpeng Special Ceramics Co., Ltd kufanele ibe ngomunye wabahlinzeki abahamba phambili ngemikhiqizo ehlukahlukene ye-Reaction Bonded SIC, efana neNozzle neminye esemandleni kagesi, izitsha zobumba, iziko, insimbi nensimbi, imayini, amalahle, i-alumina, i-petroleum, ikhemikhali. , i-desulphurization emanzi, ukukhiqizwa kwemishini, nezinye izimboni ezikhethekile emhlabeni.

I-Reaction Bonded SIC ingahlukaniswa yabai-silicon carbide ehlanganisiwe yokusabelafuthii-silicon carbide eyenziwe ngokusabela, ngokuya ngokuthi okungenalutho kokuqala kuqukethe izinhlayiya ze-silicon carbide.

I-silicon carbide ehlanganisiwe yokusabela

I-Reaction-bonded silicon carbide ibhekisela kwinqubo yokwakha inhlanganisela ye-silicon carbide. Kusesimweni lapho okungenalutho kokuqala kuqukethe i-silicon carbide powder. Enqubweni yokusabela, i-carbon ne-silicon isabela ukwakha isigaba esisha se-silicon carbide futhi ihlanganiswe ne-silicon carbide yasekuqaleni. Inqubo yokulungiselela imi kanje, okuyindlela evame ukusetshenziswa:

Ukuxuba i-silicon carbide powder, i-carbon powder kanye ne-organic binder;

Ukwakha ingxube yomile futhi iboshiwe;

Ekugcineni, ukuthola i-silicon carbide eboshwe ngokusabela ngokungeniswa kwe-silicon.

I-silicon carbide ehlanganisiwe yokusabela ekhiqizwa yile ndlela ngokuvamile iqukethe izinhlamvu zekristalu ze-silicon carbide kanye nokuqukethwe okuphezulu kwe-silicon yamahhala. Nokho, le ndlela inenqubo elula nezindleko eziphansi. Okwamanje,

I-silicon carbide eyenziwe ngokusabela

Isiqalo esingenalutho se-silicon carbide esakhiwe ngokusabela siqukethe kuphela i-carbide. Isiqalo esingenalutho se-porous carbon siphendulwa nge-silicon noma i-silicon alloy ukuze kulungiswe i-silicon carbide composite material. Le nqubo yaqala ukusungulwa ngu-Hucke. Indlela ye-Hucke nayo inezihibe zayo. Inqubo yayo yokulungiselela iyinkimbinkimbi kakhulu. Izindleko zale ndlela ziphezulu. Ngesikhathi esifanayo, inani elikhulu legesi liyashintsha ngesikhathi sokuqhekeka okushisayo. Lokhu kuzoholela ekuqhekekeni okulula kwe-china. Ngakho-ke, le ndlela inzima kakhulu ukukhiqiza imikhiqizo yosayizi omkhulu.

Ngaphezu kwalokho, i-petroleum coke isetshenziswa njengento eluhlaza ukuze kulungiswe wonke ama-carbon slabs, bese kwakhiwa i-silicon carbide. Kodwa-ke, izakhiwo zezinto ezilungiselelwe ziphansi kakhulu. Amandla ayo ngokuvamile angaphansi kuka-400mpa. Ukufana kwe-silicon carbide etholakele akukuhle. Ngenxa yezindleko eziphansi ze-petroleum coke, izindleko zale ndlela ziphansi kakhulu.

Summary

Uma kuqhathaniswa nezinye izindlela zokulungiselela ze-silicon carbide ceramics, indlela ehlanganisiwe yokusabela inezinzuzo zayo eziyingqayizivele. Njengamanje, ucwaningo kule ndawo lugxile kakhulu ocwaningweni lwenqubo ye-sintering kanye nokubonakaliswa kwesakhiwo kanye nezakhiwo zemikhiqizo. Kodwa-ke, ucwaningo lokwakheka okungenalutho lumbalwa uma kuqhathaniswa. Nakuba kunezifundo eziningi mayelana nendlela yokusabela phakathi kwazo, kukhona izifundo ezimbalwa mayelana ne-permeability kinetics, indlela yokusabela kanye nokwakheka kwesigaba sezinto zenqubo ye-alloying. Kukhona izifundo ezimbalwa mayelana nokulungiswa kwezinto ezinezakhiwo nezakhiwo ezilawulekayo ngokuhlanganiswa kokungena kwe-silicon nezinye izinto. Lezi zici zisadinga ukufundwa.
