Xa kuthathwa i-polyacrylonitrile based carbon felt njengomzekelo, ubunzima bendawo yi-500g/m2 kunye ne-1000g/m2, amandla e-longitudinal kunye ne-transverse strength (N/mm2) yi-0.12, 0.16, 0.10, 0.12, i-breaking elongation yi-3%, 4%, 18%, 16%, kunye ne-resistivity (Ω·mm) yi-4-6, 3.5-5.5 kunye ne-7-9, 6-8, ngokulandelelana. Ulawulo lobushushu beluyi-0.06W/(m·K)(25℃), indawo ethile yomphezulu yayiyi > 1.5m2/g, umxholo wothuthu wawungaphantsi kwe-0.3%, kwaye umxholo wesalfure wawungaphantsi kwe-0.03%.
I-activated carbon fiber (ACF) luhlobo olutsha lwezinto zokufunxa ezisebenza kakuhle ngaphaya kwe-activated carbon (GAC), kwaye yimveliso yesizukulwana esitsha. Inesakhiwo esiphuhlileyo se-microporous, amandla amakhulu okufunxa, isantya sokufunxa ngokukhawuleza, isiphumo esihle sokucoca, ingacutshungulwa ibe ziinkcukacha ezahlukeneyo zefelt, isilika, ilaphu. Imveliso ineempawu zokumelana nobushushu, i-asidi kunye ne-alkali.
Iimpawu zeNkqubo:
Umthamo wokufunxa we-COD, i-BOD kunye neoyile kwisisombululo samanzi uphezulu kakhulu kunowe-GAC. Ukumelana nokufunxa kuncinci, isantya siyakhawuleza, ukufunxa kuyakhawuleza kwaye kucokisekile.
Ukulungiselela:
Iindlela zokuvelisa zezi: (1) ukuhamba komoya we-carbon filament ungene kwinethi emva kokuncitshiswa; (2) Ukufakwa kwe-carbon kwi-silk felt efakwe i-oxygen; (3) Ukufakwa kwe-preoxidation kunye nokufakwa kwe-carbon kwi-polyacrylonitrile fiber felt. Isetyenziswa njengezinto zokukhusela ii-vacuum furnitures kunye nee-inert gas furnitures, ii-hot gas okanye ii-liquid and molted metal filters, ii-porous fuel cell electrodes, ii-catalyst carriers, ii-composite linings zeenqanawa ezimelana nokugqwala kunye nezinto ezidityanisiweyo.
