Ukuthatha i-polyacrylonitrile esekelwe kwikhabhoni evakalelwa njengomzekelo, ubunzima bendawo yi-500g / m2 kunye ne-1000g / m2, amandla e-longitudinal kunye ne-transverse (N / mm2) yi-0.12, 0.16, 0.10, 0.12, ukunyuka kwe-elongation yi-3%, 4%, 18%, 16%, kunye nokumelana (Ω·mm) ngu-4-6, 3.5-5.5 kunye no-7-9, 6-8, ngokulandelanayo.I-thermal conductivity yayingu-0.06W / (m·K)(25℃), indawo ethile yendawo yayi> 1.5m2 / g, umxholo womlotha wawungaphantsi kwe-0.3%, kwaye umxholo wesulfure wawungaphantsi kwe-0.03%.
I-activated carbon fiber (ACF) luhlobo olutsha lwezixhobo eziphezulu ze-adsorption ezisebenzayo ngaphaya kwekhabhoni esebenzayo (GAC), kwaye yimveliso yesizukulwana esitsha.Inesakhiwo esiphuhliswe kakhulu se-microporous, umthamo omkhulu we-adsorption, isantya esikhawulezayo se-desorption, isiphumo esihle sokucoca, sinokucutshungulwa kwiinkcukacha ezahlukeneyo zokuva, isilika, ilaphu.Imveliso ineempawu zokushisa, i-asidi kunye nokumelana ne-alkali.
Iimpawu zenkqubo:
Umthamo we-adsorption we-COD, i-BOD kunye neoli kwisisombululo se-aqueous iphezulu kakhulu kune-GAC.Ukuxhatshazwa kwe-adsorption kuncinci, isantya sikhawuleza, i-desorption ikhawuleza kwaye icokisekile.
ukulungiswa:
Iindlela zokuvelisa zezi: (1) i-carbon filament air flow in the network after needling;(2) I-carbonization ye-silk yangaphambili ene-oxygen ivakalelwa;(3) I-Preoxidation kunye ne-carbonization ye-polyacrylonitrile fiber ivakalelwa.Isetyenziswa njengezixhobo zokugquma kwiziko lokufunxa kunye negesi engasebenziyo, igesi eshushu okanye ulwelo kunye nezihluzo zetsimbi etyhidiweyo, i-electrode ye-porous fuel cell, catalyst carriers, i-linings ehlanganisiweyo yeenqanawa ezikwaziyo ukubola kunye nezixhobo ezidibeneyo.
