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

Izinhlobo ZokusabelaI-Silicone Carbide Ehlanganisiwe (RBSiC/SiSiC)

Njengamanje, kunenqwaba yabakhiqizi abahlinzeka ngemikhiqizo ye-Reaction Bonded SIC ezimbonini ezahlukene. I-Shandong Zhongpeng Special Ceramics Co., Ltd kufanele ibe ngomunye wabahlinzeki abangcono kakhulu ngemikhiqizo ye-Reaction Bonded SIC ehlukahlukene, njenge-Nozzle neminye kumandla kagesi, izinto zobumba, i-kiln, insimbi nensimbi, imayini, amalahle, i-alumina, uphethiloli, amakhemikhali, i-wet desulphurization, ukukhiqizwa kwemishini, kanye neminye imboni ekhethekile emhlabeni.

I-Reaction Bonded SIC ingahlukaniswa ibe yii-silicon carbide eboshwe ngokusabelafuthii-silicon carbide eyakhiwe ngendlela yokusabela, kuye ngokuthi indawo yokuqala engenalutho iqukethe izinhlayiya ze-silicon carbide.

I-silicon carbide eboshwe yi-reaction

I-silicon carbide eboshiwe yi-reaction-bonded ibhekisela enqubweni yokwakha i-silicon carbide composite. Kusesimweni lapho i-starting blank iqukethe i-silicon carbide powder. Enqubweni yokusabela, i-carbon ne-silicon ziyasabela ukuze zakhe isigaba esisha se-silicon carbide futhi zihlangane ne-silicon carbide yokuqala. Inqubo yokulungiselela imi kanje, okuyindlela evame ukusetshenziswa:

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

Ukwenza ingxube yome futhi ikhishwe izibopho;

Ekugcineni, ukuthola i-silicon carbide eboshiwe ngokusabela ngokungena kwe-silicon.

I-silicon carbide eboshiwe ekhiqizwa yile ndlela ngokuvamile iqukethe izinhlamvu zekristalu ze-silicon carbide eziqinile kanye nokuqukethwe okuphezulu kwe-silicon yamahhala. Kodwa-ke, le ndlela inenqubo elula nezindleko eziphansi. Okwamanje,

I-silicon carbide eyakhiwe ngendlela yokusabela

Isikhala sokuqala se-silicon carbide esakhiwe ngendlela yokusabela siqukethe i-carbide kuphela. Isikhala sokuqala se-carbon evulekile siphendulwa nge-silicon noma i-silicon alloy ukulungiselela izinto ezihlanganisiwe ze-silicon carbide. Le nqubo yasungulwa okokuqala yi-Hucke. Indlela ye-Hucke nayo inezinkinga zayo. Inqubo yayo yokulungiselela iyinkimbinkimbi kakhulu. Izindleko zale ndlela ziphakeme. Ngesikhathi esifanayo, inani elikhulu legesi liyashintsha ngesikhathi sokuqhekeka kokushisa. Lokhu kuzoholela ekuqhekekeni okulula kwe-China. Ngakho-ke, le ndlela kunzima kakhulu ukukhiqiza imikhiqizo emikhulu.

Ngaphezu kwalokho, i-petroleum coke isetshenziswa njengezinto zokusetshenziswa ukulungisa wonke ama-carbon slabs, bese kwakheka i-silicon carbide. Kodwa-ke, izakhiwo zezinto ezilungisiwe ziphansi kakhulu. Amandla ayo ngokuvamile aphansi kune-400mpa. Ukufana kwe-silicon carbide etholiwe akukuhle. Ngenxa yezindleko eziphansi ze-petroleum coke, izindleko zale ndlela ziphansi kakhulu.

Si-ummary

Uma kuqhathaniswa nezinye izindlela zokulungiselela ze-silicon carbide ceramics, indlela yokubopha ukusabela inezinzuzo zayo eziyingqayizivele. Njengamanje, ucwaningo kule ndawo lugxile kakhulu ekufundweni kwenqubo yokusinta kanye nokuchazwa kwesakhiwo nezakhiwo zemikhiqizo. Kodwa-ke, ucwaningo lokwakheka okungenalutho luncane kakhulu. Nakuba kunezifundo eziningi mayelana nendlela yokusabela phakathi kwazo, kunezifundo ezimbalwa mayelana ne-permeability kinetics, indlela yokusabela kanye nokwakheka kwesigaba sezinto zenqubo yokuhlanganisa. Kunezifundo ezimbalwa mayelana nokulungiswa kwezinto ezinezakhiwo nezakhiwo ezingalawuleki ngokuhlanganiswa kokungena kwe-silicon nezinye izinto. Lezi zici kusadingeka zifundwe.
