Silicon khabhayithi umqadi
Iinkcukacha zemveliso:
Imiqadi yesikwere se-silicon carbide yokusabela esetyenziswayo iyasebenza kulwakhiwo oluthwala imithwalo yeetunnel kilns, iivili zeshuttle, iileyile ezimbini zerolley killer kunye nezinye iikhilni zeshishini. Iimpawu zemveliso kukuba amandla obushushu aphezulu athweleyo makhulu, akukho kugobeka okanye ukusilela ekusebenziseni ixesha elide, kwaye ubomi benkonzo buphinda-phindana nobezinye izinto, yiyo loo nto ifanitshala yeziko efanelekileyo ye-porcelain yococeko kunye nezinye izinto. amashishini e-porcelain kagesi. Imveliso ibonakaliswe ngamandla aphezulu obushushu obuguquguqukayo, ukuxhathisa okothusayo, ukumelana ne-oxidation kunye nokususwa simahla ekusebenziseni ixesha elide, ngenxa yoko kunokunciphisa ngokubonakalayo ukusetyenziswa kwamandla ngaphandle kokonyusa ubunzima bemoto yeziko.
Iimpawu eziphambili zezobuchwephesha zeemveliso ze-silicon carbide
Uphawu:
Amandla obushushu aphezulu avumela ukulayishwa okunzima
b.Excellent ukuxhathisa thermal
c. Ukuqhuba okuphezulu kobushushu
d. Ukumelana ne-oxidation efanelekileyo kuguqulela kubomi obude phantsi kobushushu obuphezulu bokusebenza
Ukusetyenziswa
I-silicon nitride kunye ne-silicon carbide beams zinamandla aphezulu obushushu obuguquguqukayo, ukumelana nokunyuka kunye nokumelana ne-oxidation; isetyenziswe ikakhulu kwiiceramics zangasese, i-porcelain yombane ephezulu, iifilitha, ii-quartz crucibles; ukuchitha iipleyiti kunye neepleyiti ezimile njengentlanzi ezisetyenziswa ngokubanzi kuMzi-mveliso wokusebenzisa imihla ngemihla; ityhubhu yokukhusela isetyenziselwa ukulinganisa ubushushu kumashishini awahlukeneyo; iimveliso ezizodwa ezimile kunye nemikhono yokutshisa zisetyenziswa kakhulu kwiziko lezinto ezahlukeneyo kunye nobunjineli boomatshini.
