Xa sikhetha imveliso ye-ceramic fiber, ngokuqinisekileyo siya kubuza umenzi ngedatha yokusebenza ephambili yemveliso kwaye siqonde ixabiso ledatha yereferensi ekukhethweni, kodwa mhlawumbi umthengi akacaci kakuhle malunga nentsingiselo yexabiso okanye enye entsha. abathengi abayiqondi intsingiselo yedatha, soloko ubonisana nathi malunga nentsingiselo yedatha.Namhlanje i-100 ijonga ukuba uchaze iimveliso ze-ceramic fiber kolu lwazi luncinci, ndiyathemba ukukunceda!
1 Umahluko phakathi kwezinto zokufakelwa kwe-thermal kunye nezixhobo eziphikisayo
Xa sithetha ngokubanzi, ngaphantsi kwe-1570℃ ibizwa ngokuba yi-insulation material;Ngaphezulu kwe-1570 ℃ zizinto eziphikisayo.Izixhobo zemveli ezichasayo ngokubanzi zibhekisa kwizitena zomlilo ezinzima, eziphoswayo, njl. njl., Ubuninzi bomthamo ngokuqhelekileyo yi-1000-2000kg/m3.
Iinzuzo zefiber ye-ceramic zicacile kakhulu, phantsi kwesiseko sokusebenza kakuhle kwe-thermal insulation, kodwa inokumelana nomlilo okulungileyo, kwaye iyinto yokukhanya, ukunciphisa umthwalo weziko, ukunciphisa kakhulu ukufakwa kwendabuko ngenxa yenkxaso enzima. izinto ezidliwe yinani elikhulu lentsimbi.
2 ukushwabana kocingo olushushu
Isalathiso sokuvavanya ukumelana nobushushu (ubushushu benkonzo) yeemveliso ze-ceramic fiber.Iimfuno ezimanyeneyo zamazwe ngamazwe zeemveliso ze-ceramic fiber phantsi kokufudumeza okungekho umthwalo kwiqondo elithile lobushushu, ukugcinwa kobushushu kwiiyure ezingama-24 zomgca wokushisa ophezulu wokunciphisa ubushushu kubonisa ukuxhathisa ubushushu be-ceramic fiber.
Ubushushu bovavanyo lwexabiso lokucutha kwecingo lokufudumeza ≤3% lubushushu benkonzo eqhubekayo yeemveliso zefiber zeceramic.Kulo bushushu, iifiber ze-amorphous ze-ceramic zikhanya kwaye zikhula ngokukhawuleza, kwaye iimpawu zefiber zizinzile kwaye zi-elastic.
Ixabiso lokucutheka kocingo lokufudumeza ≤4% lobushushu bovavanyo lwemveliso yefibre yeceramic sebenzisa ubushushu.
3 I-Thermal conductivity
I-Thermal conductivity luhlobo lwepropathi ebonakalayo yezinto eziphathekayo, okuyisalathiso sepropathi ye-thermal insulation ye-ceramic fiber.
Kuxhomekeke kwisakhiwo seemveliso ze-ceramic fiber, ukuxinana kwevolumu, ubushushu, umoya wesithando somlilo, ukufuma kunye nezinye izinto.
Ifiber yeCeramic ngumxube wefiber eqinileyo kunye nomoya one-porosity ye-93%.Isixa esikhulu somoya esine-conductivity ephantsi ye-thermal sizaliswe kwii-pores, kwaye isakhiwo sothungelwano esiqhubekayo sama-molecule aqinileyo kutshatyalaliswa, ukuze kufumaneke ukusebenza kakuhle kwe-adiabatic.Kwaye incinci i-diameter ye-pore, ecaleni kwendlela yokuhamba kobushushu ngefiber eqinileyo eyahlulwe kwimo evaliweyo yenani leepores, ngcono ukusebenza kwe-thermal insulation yefiber ye-ceramic.
4. Impembelelo yokwakheka kweekhemikhali
Ubume bekhemikhali bumisela ngokuthe ngqo ukuxhathisa ubushushu befiber:
(1) I-Al2O3, i-SiO2, i-ZrO2, i-Cr2O3 kunye nezinye izinto ezisebenzayo ≥99%, umxholo we-oxide weqondo lokushisa eliphezulu, unquma ngokuthe ngqo ukusebenza kwefiber ye-ceramic.
(2) I-Fe2O3, i-Na2O, i-K2O, i-MgO kunye nezinye izinto ezingcolileyo ezingaphantsi kwe-1%, zezobumdaka obunobungozi, zikhokelela ngokuthe ngqo ekudakaleni kwe-ceramic fiber performance.
