I-silicon carbide ceramics: inguquko ezingxenyeni ezingagugi embonini yezimayini

Izitsha zobumba ze-silicon carbide: inguquko enkuluizingxenye ezingagugiembonini yezimayini

Imboni yezimayini yaziwa ngokusebenza kwayo kanzima, ikakhulukazi emkhakheni wokuwasha izimayini, lapho imishini ivame ukuchayeka ezintweni ezihuzukayo. Esimweni esinzima kangaka, isidingo sezingxenye ezingagugi sibaluleke kakhulu. Yilapho ukusetshenziswa kwezitsha zobumba ze-silicon carbide kuqala khona ukusebenza, okuhlinzeka ngezixazululo ezishintsha umdlalo embonini yezimayini.

I-silicon carbide ceramics isibe yinto efanelekile yezingxenye ezahlukahlukene ezisetshenziswa emisebenzini yezimayini ngenxa yobunzima bazo obuhle kakhulu kanye nokumelana nokuguguleka okunamandla. Embonini yokucubungula amaminerali ensimbi, i-silicon carbide ceramics isetshenziswa kabanzi kuma-impellers, amakamelo okupompa, amapayipi angagugi, ama-cyclone, ama-hopper linings, njll. Zinokumelana okuhle kakhulu nokuguguleka, okuphindwe ka-5-20 kunenjoloba nensimbi ephonswe, okwenza zibe yinto ebalulekile ekumelaneni nokuguguleka kwezinqubo zokuwasha zezimayini.

Izakhiwo eziyingqayizivele ze-silicon carbide ceramics zizenza zifaneleke kakhulu embonini yezimayini. Ubulukhuni bazo obungavamile, obulandela idayimani kuphela, buqinisekisa ukuthi zingakwazi ukumelana nezimo ezinzima ezivame kakhulu emisebenzini yezimayini. Lobu bulukhuni obuhlangene nokumelana nokuguguleka okunamandla kwenza kube kuhle kakhulu ezingxenyeni eziguguleka njalo futhi ziguguleke.

Ngaphezu kwalokho, ukumelana nokuguguleka kwe-silicon carbide ceramics kwandisa isikhathi sokusebenza kwazo futhi kunciphisa ukuvama kokushintsha nokulungisa, ngaleyo ndlela kusiza ukonga izindleko ekusebenzeni kwezezimayini. Lokhu kuqina nokuphila isikhathi eside kuzenza zibe yisisombululo esingabizi kakhulu embonini yezezimayini, lapho ukuthembeka kwemishini nokusebenza kwayo kubalulekile khona.

Ngaphezu kwalokho, ukusetshenziswa kwe-silicon carbide ceramics akugcini nje embonini yezimayini. Izakhiwo zazo ezinhle kakhulu zizenza zibe yinto efanelekile yezindiza, ikakhulukazi ekwakhiweni kwemigwaqo yezindiza, lapho ukumelana nokuguguleka kwazo nokuqina kwazo kwaziswa kakhulu.

Ngamafuphi, ukusetshenziswa kwe-silicon carbide ceramics embonini yezimayini kushintshe kakhulu ukukhiqizwa kwezingxenye ezingagugi. Ubulukhuni bayo obungavamile, ukumelana nokuguguleka okunamandla kanye nokusebenza kahle kwezindleko kwenza kube ukukhetha okubalulekile kwezingxenye ezisetshenziswa ekuhlanzeni izimayini kanye neminye imisebenzi yezimayini. Njengoba imboni yezimayini iqhubeka nokuthuthuka, i-silicon carbide ceramics izodlala indima ebalulekile ekuthuthukiseni ukusebenza kwemishini kanye nempilo yesevisi, ekugcineni ibe negalelo ekusebenzeni kahle kanye nokusimama kwemisebenzi yezimayini.
