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. IShandong Zhongpeng Special Ceramics Co., Ltd kufanele ibe ngomunye wabahlinzeki abahamba phambili ngemikhiqizo ehlukahlukene yeReaction Bonded SIC, efana neNozzle neminye esemandleni kagesi, izitsha zobumba, iziko, insimbi nensimbi, imayini, amalahle, i-alumina, i-petroleum, amakhemikhali, 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, ikhabhoni ne-silicon zisabela ukuze kwakhiwe isigaba esisha se-silicon carbide futhi kuhlanganiswe 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 nguHucke. 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. Nokho, ucwaningo mayelana nokwakheka 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.
