Ukuthola i-Ceramic fiber ukuthi yiluphi ulwazi lokuthola

Uma sikhetha umkhiqizo we-ceramic fiber, ngokuqinisekile sizobuza umenzi ngedatha yokusebenza eyinhloko yomkhiqizo futhi siqonde inani ledatha lereferensi ekukhetheni, kodwa mhlawumbe ikhasimende alicaci kahle ngencazelo yenani noma okusha. amakhasimende awaqondi incazelo yedatha, njalo athintane nathi mayelana nencazelo yedatha.Namuhla i-100 ihlolela wena ukuchaza imikhiqizo ye-ceramic fiber yalolu lwazi oluncane, ngithemba ukukusiza!

1 Umehluko phakathi kwezinto zokufaka ezishisayo nezinto eziphikisayo

Ngokuvamile, ngaphansi kwe-1570 ℃ kubizwa ngokuthi impahla yokufakelwa;Ngaphezulu kwe-1570 ℃ yizinto eziphikisayo.Izinto zendabuko eziphikisayo ngokuvamile zibhekisela ku-firebrick esindayo, ephonswayo, njll., ukuminyana kwevolumu ngokuvamile kungu-1000-2000kg/m3.

Izinzuzo ze-ceramic fiber zisobala kakhulu, ngaphansi kwesisekelo sokusebenza okuhle kakhulu kokushisa okushisayo, kodwa futhi kunokumelana nomlilo okuhle, futhi kungokwezinto ezikhanyayo, ukunciphisa umthwalo wesithando somlilo, ukunciphisa kakhulu ukufakwa kwendabuko ngenxa yokusekelwa kwesisindo esinzima. izinto ezidliwe yinani elikhulu lensimbi.

2 intambo eshisayo ishwabana

Inkomba yokuhlola ukumelana nokushisa (izinga lokushisa lensiza) lemikhiqizo ye-ceramic fiber.Izidingo ezihlangene zomhlaba wonke zemikhiqizo ye-ceramic fibre ngaphansi kokushisisa okungalayishwa ezingeni elithile lokushisa, ukugcinwa kokushisa amahora angu-24 wokunciphisa umugqa wokushisa ophakeme kubonisa ukumelana nokushisa kwe-ceramic fiber.

Izinga lokushisa lokuhlola lenani lokuncibilika kwentambo yokushisisa ≤3% izinga lokushisa lesevisi eliqhubekayo lemikhiqizo ye-ceramic fiber.Kuleli zinga lokushisa, imicu ye-amorphous ceramic icwebezela futhi ikhule kancane, futhi izakhiwo zefiber zizinzile futhi ziyanwebeka.

Inani lokuncipha kwentambo yokushisisa ≤4% izinga lokushisa lokuhlola lemikhiqizo ye-ceramic fiber isebenzisa izinga lokushisa.

3 Thermal conductivity

I-thermal conductivity iwuhlobo lwempahla ebonakalayo yezinto ezibonakalayo, okuyinkomba yempahla yokushisa eshisayo ye-ceramic fiber.

Kuncike ekwakhekeni kwemikhiqizo ye-ceramic fiber, ukuminyana kwevolumu, izinga lokushisa, umkhathi wesithando somlilo, umswakama nezinye izici.

I-Ceramic fiber iyingxube yefayibha eqinile nomoya one-porosity engama-93%.Inani elikhulu lomoya eline-conductivity ephansi yokushisa ligcwele ama-pores, futhi isakhiwo senethiwekhi esiqhubekayo sama-molecule aqinile siyabhujiswa, ukuze kutholakale ukusebenza okuhle kakhulu kwe-adiabatic.Futhi lapho i-diameter ye-pore incane, eduze nokuqondisa kokugeleza kokushisa ngefayibha eqinile ihlukaniswe yaba isimo esivaliwe senani lezimbotshana, kuba ngcono ukusebenza kokushisa okushisayo kwe-ceramic fiber.

4. Ithonya lokwakheka kwamakhemikhali

Ukwakheka kwamakhemikhali kunquma ngokuqondile ukumelana nokushisa kwe-fiber:

(1) I-Al2O3, SiO2, ZrO2, Cr2O3 nezinye izingxenye ezisebenzayo ≥99%, okuqukethwe kwe-oxide yezinga lokushisa eliphezulu, inquma ngokuqondile ukusebenza kwe-ceramic fiber.

(2) I-Fe2O3, i-Na2O, i-K2O, i-MgO nokunye ukungcola okungaphansi kuka-1%, kungokwezinto ezingcolile eziyingozi, kuholela ngokuqondile ekuwohlokeni kokusebenza kwe-ceramic fiber.
