Tšusumetso ea silicon carbide (SiC) ho thepa ea li-castable
Tšusumetso ea silicon carbide (SiC) ka thepa ea li-castables
⑴ Kaha SiC ka boeona ha e na metsi, ha ho bonolo ho kolobisoa, ‘me ha ho bonolo ho etsa lera la filimi ea metsi,’ me tšebeliso ea metsi e ntseng e sebelisoa ea eketseha. Ka hona, li-content tsa SiC tse phahameng, ts’ebetso e futsanehileng ea ho sebetsa le ho phalla ha metsi, ‘me matla a batang a batang a tla fokotseha.
⑵ Kaha bongata ba SiC (2.6 ~ 2.8g / cm3) bo boholo ho feta boima ba li-ceramics (2.2 ~ 2.4g / cm3), ha SiC e ntse e le ngata, ho ba le boholo ba molumo oa thepa. Ha mocheso o phahama ‘me litaba tsa SiC li phahame, boima ba molumo bo tla eketseha ho isa tekanyong e itseng. Likahare tsa SiC li bonts’a boleng bo bobe bakeng sa tšusumetso ea phetoho ea mohala oa thepa.
⑶ Likahare tsa SiC li na le molemo ho matla a ho lahlela, haholo-holo mocheso o phahameng (1100 ° C). Haholo-holo ha boholo ba karolo ea SiC e le 150 mesh, e ke ke ea e-ba oxidized ka ho feletseng, ‘me likheo tse ling li thehoa ho pota-potile likaroloana tsa SiC, tse ntlafatsang ho hanyetsa mocheso oa mocheso le matla a ho lahla. SiC ea unoxidized e boetse e sebetsa joalo ka matlafatso ea likaroloana.
⑷ Ha litaba tsa SiC li le ngata, li ntlafatsa ts’ebetso ea thepa e khahlanong le letlalo.
⑸ Ha litaba tsa SiC li le ngata, li ntlafatsa khanyetso ea alkali.
