Iyo pesvedzero yesilicon carbide (SiC) pane zvivakwa zve castables
Simba re nesilicon carbide (SiC) pane zvivakwa zve castables
⑴ Sezvo SiC pachayo ichidzivirira mvura, hazvisi nyore kunyorova, uye hazvisi nyore kuumba firimu remvura, uye kushandiswa kwemvura kweiyo inokandwa kunowedzera. Naizvozvo, iyo yakakwirira yeSiC yemukati, kushomeka kwekushanda uye kuyerera kweiyo inokandwa, uye inotonhora inoshanduka simba inoderera.
⑵ Sezvo kuwanda kweSiC (2.6 ~ 2.8g / cm3) kwakakura kudarika kuwanda kwemakeramics (2.2 ~ 2.4g / cm3), iyo yakawanda SiC yemukati, iyo yakakura vhoriyamu density yechinhu. Kana tembiricha yakwira uye iyo SiC yemukati yakakwira, iyo vhoriyamu density ichawedzera kune imwe nhanho. Iyo SiC yemukati inoratidza kukosha kwakashata kwesimba rekuchinja kwezvinhu mutsara.
⑶ SiC yemukati inobatsira kune kusimba kweiyo inokandwa, kunyanya pakupisa kwakanyanya (1100 ° C). Kunyanya kana iyo SiC particle size iine 150 mesh, haigone kuve yakazara oxidized, uye mamwe magapu anoumbwa akatenderedza SiC zvidimbu, izvo zvinovandudza kupisa kwekuvhunduka uye simba reiyo inokandwa. Iyo inoxidized SiC inoshandawo sechinhu chinosimbisa.
⑷ Iyo yakawanda yeSiC yemukati, zviri nani zvezvinhu zvinopesana neganda kuita.
⑸ Iyo yakawanda yeSiC yemukati, zviri nani iyo alkali kuramba.
