Silicon Carbide SiC Coated Heaters

Tlhaloso e Khutšoanyane:

Silicon carbide heater e koahetsoe ka tšepe ea oxide, ke hore, poleiti e hole ea infrared silicon carbide e le karolo ea radiation, ka har'a lesoba la element (kapa groove) ka har'a terata e futhumatsang ea motlakase, ka tlase ho poleiti ea silicon carbide e kenya mokelikeli o motenya, oa refractory. , thepa ea ho kenya mocheso, ebe e kenngoa holim'a khetla ea tšepe, terminal e ka sebelisoa ho hokahanya phepelo ea matla.

Ha lehlaseli le hole la infrared la silicon carbide heater le khanyetsa nthong, le ka monya, la bonahatsa le ho feta. Thepa e futhumetseng le e omisitsoeng e monya matla a mahlaseli a kotsi ka botebo bo itseng ba limolek'hule tsa ka hare le holim'a metsi ka nako e le 'ngoe, ho hlahisa phello e futhumatsang, e le hore limolek'hule tsa solvent kapa metsi li fetohe mouoane' me li futhumale ka tsela e tšoanang, kahoo li qoba ho senyeha le ho fetoha ha boleng. ka lebaka la likhato tse fapaneng tsa ho atolosoa ha mocheso, e le hore ponahalo ea thepa, thepa ea 'mele le ea mechine, ho potlaka le mmala li lule li tiile.

Tlhaloso

Khamphani ea rona e fana ka lits'ebeletso tsa ts'ebetso ea ho roala SiC ka mokhoa oa CVD holim'a graphite, li-ceramics le lisebelisoa tse ling, e le hore likhase tse khethehileng tse nang le carbon le silicon li sebetsane le mocheso o phahameng ho fumana limolek'hule tsa SiC tse hloekileng, limolek'hule tse behiloeng holim'a thepa e koahetsoeng, ho etsa lera la tšireletso la SIC.

Likarolo tse ka Sehloohong

1. Ho hanyetsa mocheso o phahameng oa oxidation:
khanyetso ea oxidation e ntse e le ntle haholo ha mocheso o le holimo ho 1600 C.
2. Bohloeki bo phahameng: bo entsoeng ka ho kenngoa ha mouoane oa lik'hemik'hale tlas'a boemo bo phahameng ba mocheso oa chlorination.
3. Ho hanyetsa khoholeho ea mobu: boima bo phahameng, bokaholimo bo kopanetsoeng, likaroloana tse ntle.
4. Ho hanyetsa kutu: acid, alkali, letsoai le li-reagents tse phelang.
