Isiqalelo sokufudumeza seSiC
Izintonga zeSilicon Carbide (SiC), ezaziwa ngokuba zizinto zokufudumeza ze-silicon carbide, zizinto zokufudumeza ezingezizo ezesinyithi ezisebenza kakuhle, ezenziwe nge-SiC eluhlaza ene-hexagonal ecocekileyo kakhulu nge-2200℃ yokutshisa ubushushu obuphezulu. Zinokumelana nobushushu obuphezulu (ukuya kuthi ga kwi-1450℃), isantya sokufudumeza esikhawulezayo, ubomi benkonzo ende, kunye nokufakelwa okulula, zilungele izitofu zoshishino ezishushu kakhulu kunye nezixhobo zesayensi.
Iimodeli eziphambili kunye nezicelo:
(1) Uthotho lwe-GD (Iintonga ezilinganayo zobubanzi)
Uyilo olufanayo ngobubanzi, isakhiwo esilula kunye nexabiso eliphantsi. Ifanelekile kwiifeni ezincinci zebhokisi, iifeni ezithambileyo kwiilebhu kunye nemveliso encinci. Iinkcukacha eziqhelekileyo: Φ8–Φ40mm, ubude 200–2000mm.
(2) Uthotho lweeCD (Iintonga eziThick-end)
Iziphelo ezibandayo ezinkulu zinciphisa ukulahleka kobushushu, zisebenza kakuhle ekufudumaleni kwaye zihlala ixesha elide. Zifanelekile kwii-kilns ezinkulu ze-tunnel, ii-roller kilns kunye nee-smelting furniture kwimizi-mveliso ye-ceramic, i-glass. Iinkcukacha eziqhelekileyo: icandelo lokufudumeza Φ8–Φ30mm, i-thick-end Φ20–Φ60mm.
(3) Uthotho lwe-U (Iintonga ezimile okwe-U)
I-U-shape egobileyo yokufaka ngqo, igcina indawo ye-furnace. Isetyenziswa kakhulu kwii-furnace ezincinci ze-vacuum kunye nezixhobo ze-ceramic sintering.
(4) Iintonga ezimile ngokwesiko
Iintambo ezilungiselelwe uhlobo lwe-W, uhlobo lwe-plum-blossom, ezifakwe imisonto ziyafumaneka kwizakhiwo ezikhethekileyo ze-oven kunye neemfuno zokufudumeza.
Ukumelana nobushushu obuphezulu:Kwindawo ene-oxidizing, ubushushu obuqhelekileyo bokusebenza bunokufikelela kwi-1450℃, kwaye bungasetyenziswa rhoqo ukuya kuthi ga kwiiyure ezingama-2000.
Ukumelana kakuhle ne-oxidation:Xa ifudunyezwa emoyeni owomileyo kumaqondo obushushu aphezulu, umaleko okhuselayo we-silicon dioxide (SiO₂) wenziwa phezu komphezulu wentonga ye-silicon carbide, ewunika ukumelana okunamandla kwe-oxidation.
Uzinzo oluhle lweekhemikhali:Inokumelana ne-asidi enamandla. Nangona kunjalo, idlakazwa zizinto ze-alkaline xa kushushu kakhulu.
Isantya sokufudumeza esikhawulezayo:Ineempawu zokufudumeza ngokukhawuleza, nto leyo enokunyusa ngokukhawuleza ubushushu bento eshushu ukuya kwinqanaba elifunekayo, iphucule ukusebenza kakuhle kwemveliso.
Ubomi benkonzo ende:Xa zisetyenziswa kwaye zigcinwa kakuhle, iintonga ze-silicon carbide zinobomi obude benkonzo, nto leyo enciphisa ukuphindaphindeka kweendleko zokutshintshwa kunye nokugcinwa kwazo.
Ukufakwa nokugcinwa lula:Isakhiwo silula, kwaye kulula ukuyifaka nokuyigcina ikwimeko entle. Ingadityaniswa ngokulula nenkqubo yolawulo lwe-elektroniki oluzenzekelayo ukuze kufezekiswe ulawulo oluchanekileyo lobushushu.
