Silicon carbide tubali

1. Babban abun ciki na tubalin carbide silicon shine SiC, abun cikin shine 72%-99%. Ana amfani da tubalin carbide na siliki a masana’antu daban -daban da kayan zafi saboda haduwa daban -daban. Dangane da hanyoyin haɗin gwiwa daban -daban, masana’antun bulo na carbide na silicon sun kasu zuwa haɗin yumbu, haɗin Sialon, haɗin alumina, haɗin kai, babban haɗin aluminium, haɗin silicon nitride, da sauransu. Menene amfanin tubalin carbide na silicon? Menene manyan aikace -aikacen?

2. Saboda albarkatun bulo na carbide silicon carbide silicon carbide, silicon carbide, wanda kuma aka sani da emery, ana yin shi ne ta hanyar ƙona ɗanyen kayan zafi kamar yashi ma’adini, coke, da kwakwalwan itace. Silicon carbide galibi ana amfani da shi don yin rashi na ci gaba saboda tsayayyen kaddarorinsa na sinadarai, haɓakaccen yanayin zafi, ƙarancin faɗaɗawar zafi, da juriya mai kyau.

3. Ana sarrafa tubalin carbide carbide cikin manyan murhun murhun murhun wuta ta amfani da sifofin carbide na silicon kamar juriya na lalata, tsayayyar zafin jiki, ƙarfi mai ƙarfi, ingantaccen ɗabi’ar zafi, da juriya mai tasiri, kuma ana amfani da su a cikin ɗimbin yawan zafin jiki. kayan zafi.

4. Samfuran carbide na siliki suna amfani da carbide na silicon azaman albarkatun ƙasa, ƙara yumɓu, silicon oxide da sauran masu ɗaurin gindi zuwa sinter a 1350 zuwa 1400 ° C. Silicon carbide da silicon foda kuma ana iya yin su cikin samfuran carbide silicon nitride-silicon a cikin yanayin nitrogen a cikin tanderun wutar lantarki. Kayayyakin Carbon suna da ƙarancin ƙarancin zafi mai zafi, babban ƙarfin kwandon shara, kyakkyawan juriya na zafi, da ƙarfin zafin zafin. Ba ya yin laushi bayan amfani na dogon lokaci a babban zafin jiki, babu wani acid da alkali da yake lalata shi, yana da juriya mai kyau, kuma ba a jiƙa shi da ƙarfe da slag ba. Yana da nauyi a cikin nauyi kuma yana da inganci mai tsayayyen yanayin zafi. Rashin hasara shi ne cewa yana da sauƙi don yin oksidis a cikin zafin jiki mai yawa kuma bai dace da amfani ba a cikin yanayin iska. Ana amfani da samfuran Carbon a cikin manyan murhun murhun murhu mai zafi (ƙasan tanderu, murhu, ƙaramin sashin wutar makera, da sauransu), da kuma rufin murhun murhun ƙarfe mara ƙarfe.
