Ukuthatha i-polyacrylonitrile esekelwe kukhabhoni ezwakele njengesibonelo, isisindo sendawo singama-500g/m2 kanye no-1000g/m2, amandla e-longitudinal kanye naguquguqukayo (N/mm2) angu-0.12, 0.16, 0.10, 0.12, ubude obuphukayo bungu-3%, 4%, 18%, 16%, kanye nokumelana (Ω·mm) ngu-4-6, 3.5-5.5 no-7-9, 6-8, ngokulandelana. I-thermal conductivity yayingu-0.06W/(m·K)(25℃), indawo ethize yayiyi> 1.5m2/g, umlotha wawungaphansi kuka-0.3%, kanti isibabule wawungaphansi kuka-0.03%.
I-activated carbon fiber (ACF) iwuhlobo olusha lwe-adsorption material esebenza kahle kakhulu ngale kwe-activated carbon (GAC), futhi iwumkhiqizo wesizukulwane esisha. Inesakhiwo esithuthuke kakhulu se-microporous, umthamo omkhulu we-adsorption, isivinini esisheshayo se-desorption, umphumela omuhle wokuhlanza, ingacutshungulwa ibe yizinhlobonhlobo zokucaciswa kokuzizwa, usilika, indwangu. Umkhiqizo unezici zokushisa, i-asidi ne-alkali ukumelana.
Izici zenqubo:
Umthamo we-adsorption we-COD, BOD namafutha esixazululweni se-aqueous uphakeme kakhulu kunalowo we-GAC. Ukumelana ne-adsorption kuncane, ijubane liyashesha, i-desorption iyashesha futhi iphelele.
ukulungiselela:
Izindlela zokukhiqiza yilezi: (1) ukugeleza komoya kwe-carbon filament ungene enetheni ngemva kokuwudinga; (2) I-carbonization ye-pre-oxygenated silk ezwayo; (3) I-Preoxidation kanye ne-carbonization ye-polyacrylonitrile fiber izwakele. Isetshenziswa njengezinto zokuvikela eziko kanye nezisefo zegesi engasebenzi, igesi eshisayo noma izihlungi zensimbi eziwuketshezi nezincibilikisiwe, ama-electrode amaseli kaphethiloli ambobo, izithwali ze-catalyst, izintambo eziyinhlanganisela zemikhumbi engagqwali nezinto eziyinhlanganisela.
