Silicon carbide ke ntho e thata ka ho fetisisa (Mohs hardness 9.25), ha e na lik'hemik'hale 'me ha e qhibilihe. Silicon Carbide e na le conductivity e phahameng ea mocheso, coefficient e tlase ea katoloso ea mocheso, e na le ts'isinyeho ea mocheso le abrasion ebile e na le matla mochesong o phahameng. Thepa e fapaneng ea Silicon carbide e e etsa sesebelisoa se sebetsang lits'ebetsong tse ngata tse fapaneng.
Silicon carbide e na le mefuta e 'meli e tloaelehileng ea mantlha: silicon carbide e ntšo le silicon carbide e tala. Black silicon carbide e na le sic e ka bang 95%, kahoo ho thatafala ho phahame ho feta silicon carbide e tala. E sebelisoa haholo bakeng sa ho sebetsana le lisebelisoa tse tlaase tsa matla tse kang khalase, li-ceramics, lejoe, thepa ea refractory, tšepe e entsoeng ka tšepe le tšepe e sa tsitsang joalo-joalo. Silicone carbide e tala e na le sic e ka bang 97% ka holimo ka ho itšeha hantle, kahoo e sebelisetsoa ho sebetsana le motsoako o thata. , motsoako oa titanium le khalase ea optical hammoho le baki ea cylinder le lisebelisoa tse ntle tsa ho seha.
Melemo:
Silicon carbide e na le lik'hemik'hale tse tsitsitseng, conductivity e phahameng ea mocheso, coefficient e tlaase ea ho eketsa mocheso, le ho hanyetsa ho apara hantle. Ntle le ho sebelisoa e le li-abrasives, ho na le lisebelisoa tse ling tse ngata, tse kang: ho roala silicon carbide phofo holim'a li-impellers tsa turbine tsa metsi kapa li-cylinder blocks tse nang le ts'ebetso e khethehileng Lerako le ka hare le ka ntlafatsa ho hanyetsa ha lona le ho lelefatsa bophelo ba ts'ebeletso ka makhetlo a 1 ~ 2. ; thepa ea refractory e entsoeng ka eona e na le ho hanyetsa mocheso oa mocheso, boholo bo fokolang, boima bo bobebe le matla a phahameng, 'me e na le phello e ntle ea ho boloka matla. Silicon carbide ea boemo bo tlase (e nang le hoo e ka bang 85% SiC) ke deoxidizer e ntle haholo. E ka potlakisa lebelo la ho etsa tšepe, 'me ea bebofatsa taolo ea sebopeho sa lik'hemik'hale le ho ntlafatsa boleng ba tšepe. Ntle le moo, silicon carbide e boetse e sebelisoa haholo ho etsa lithupa tsa silicon carbide bakeng sa likarolo tsa ho futhumatsa tsa motlakase.

Kopo:
1. Ntlafatsa ho hanyetsa mocheso, ho hanyetsa ho roala le ho hanyetsa oxidation ka thepa ea refractory le indasteri ea metallurgy ea matla.
2. Lintho tse bonahalang tse tala tse phahameng polymer ea manyolo silicon fomata.
3. Iron base alloy additive, alloy pharmaceutical ea tšepe ea silicon, kahoo e ntlafatsa ho thatafala ha tšepe.
4. E sebelisoa tlhahisong ea thepa ea mocheso o phahameng e le ho etsa li-enamel le lipitsa tsa letsopa le ho hlahisa liphaphatha tsa silicon tse hloekileng haholo.

P: Na u moetsi kapa mohoebi?
A: Re bahoebi, 'me lihlahisoa tsa rona ke tsa boleng bo phahameng le theko e tlaase.
P: Na boleng ba lihlahisoa tsa hau bo tsitsitse?
A: Lihlahisoa tsa rona li na le tlhahlobo ea boleng, 'me boleng bo botle haholo.
P: O ka fana ka mehlala?
A: E, re ka fana ka mehlala ea mahala ka mor'a hore u lefelle thepa e itseng.
P: Na lihlahisoa tsa hau li tlisoa ka nako?
A: Ka kakaretso, re fana ka thepa ka nako.
P: Mekhoa ea hau ea ho bokella ke efe?
A: Mekhoa ea rona ea pokello e kenyelletsa T/ T, L / C, joalo-joalo.
