- UBUHLE BOKUSENZA IBONDED I-SILICON CARBIDE
Imikhiqizo ye-Reaction Bonded Silicon Carbide (RBSC, noma i-SiSiC) inikezela ngokuqina okwedlulele/ukumelana nemihuzuko kanye nokuzinza kwamakhemikhali okuvelele ezindaweni ezinolaka. I-Silicon Carbide iyimpahla yokwenziwa ekhombisa izici zokusebenza okuphezulu okubandakanya:
lUkumelana kwamakhemikhali okuhle kakhulu.
Amandla e-RBSC acishe abe ngama-50% amakhulu kunalawo ama-silicon carbides amaningi ahlanganiswe ne-nitride. I-RBSC iwukumelana nokugqwala okuhle kakhulu kanye ne-antioxidation ceramic. Ingakhiwa ibe izinhlobonhlobo ze-desulpurization nozzle (FGD) .
lUkuguga okuhle kakhulu nomthelela ukumelana.
Iphezulu kakhulu yobuchwepheshe be-ceramic obungazweli ngezinga elikhulu. I-RBSiC inobunzima obuphakeme obusondela kulokho kwedayimane. Idizayinelwe ukusetshenziswa ezinhlelweni zomumo abakhulu lapho amamaki aphikisayo e-silicon carbide ebonisa ukuguga okulimazayo noma ukulimala okuvela kumthelela wezinhlayiya ezinkulu. Imelana nokungena okuqondile kwezinhlayiya zokukhanya kanye nomthelela kanye nokuhushulwa okuqinile okuqinile okuqukethe ama-slurries. Ingakhiwa ibe yizinhlobonhlobo zomumo, okuhlanganisa ukubunjwa kwekhoni kanye nemikhono, kanye nezingcezu zobunjiniyela eziyinkimbinkimbi ezidizayinelwe okokusebenza okubandakanyekayo ekucutshungulweni kwezinto ezingavuthiwe.
lUkumelana nokushaqeka okuhle kakhulu kwe-thermal.
Izingxenye ze-silicon carbide eziboshiwe zinikeza ukumelana nokushaqeka okushisayo kodwa ngokungafani nezitsha zobumba zendabuko, ziphinde zihlanganise ukuminyana okuphansi namandla aphezulu emishini.
lAmandla aphezulu (ithola amandla ekushiseni).
I-Reaction bonded I-Silicon carbide igcina amandla ayo amaningi emishini emazingeni okushisa aphakeme futhi ibonisa amazinga aphansi kakhulu okukhasa, okuyenza ibe ukukhetha kokuqala kwezinhlelo zokusebenza ezithwala umthwalo ebangeni elingu-1300ºC kuya ku-1650ºC (2400ºC kuya ku-3000ºF).

- Icala LemboniMayelana ne-Reaction Bonded Silicon Carbide:
Ukukhiqiza Amandla, Izimayini, Amakhemikhali, I-Petrochemical, I-Kiln, Imboni yokukhiqiza Imishini, Amaminerali & Metallurgy nokunye.
Kodwa-ke, ngokungafani nezinsimbi nama-alloys azo, azikho izindlela ezijwayelekile zokusebenza kwemboni ye-silicon carbide. Ngezinhlobonhlobo zezingoma, ukuminyana, amasu okukhiqiza kanye nesipiliyoni senkampani, izingxenye ze-silicon carbide zingahluka kakhulu ngokuvumelana, kanye nezakhiwo zemishini namakhemikhali. Ukukhetha kwakho umphakeli kunquma izinga nekhwalithi yezinto ozitholayo.
