Qaadashada kaarboonka ku salaysan polyacrylonitrile ayaa dareemay tusaale ahaan, miisaanka aaggu waa 500g/m2 iyo 1000g/m2, dhererka iyo xoogga leexsan (N/mm2) waa 0.12, 0.16, 0.10, 0.12, dhererka jaban waa 3%, 4%, 18%, 16%, iyo iska caabinΩ·mm) waa 4-6, 3.5-5.5 iyo 7-9, 6-8, siday u kala horreeyaan.Dareenka kulaylka ayaa ahaa 0.06W/(m·K) (25℃), bedka dusha gaarka ah wuxuu ahaa> 1.5m2/g, waxa ku jira dambasku wuxuu ka yaraa 0.3%, iyo maadada baaruuddu waxay ka yaraatay 0.03%.
Fiber kaarboon firfircoon (ACF) waa nooc cusub oo wax ku oolnimo sare leh oo ka baxsan kaarboonka firfircoon (GAC), waana badeeco jiil cusub.Waxay leedahay qaab-dhismeedka microporous si heer sare ah loo horumariyay, awoodda xayeysiinta weyn, xawaaraha desorption degdega ah, saamaynta nadiifinta wanaagsan, waxaa lagu baaraandegi karaa noocyo kala duwan oo tilmaamo ah oo dareemay, xariir, maro.Alaabta ayaa leh sifooyinka kulaylka, caabbinta acid iyo alkali.
Tilmaamaha habka:
Awoodda adsorption ee COD, BOD iyo saliidda ee xalka aqueous ayaa aad uga sarreeya kan GAC.Iska caabbinta xayeysiisku waa mid yar, xawaaruhu waa dhakhso, desorption waa mid degdeg ah oo dhamaystiran.
diyaarinta:
Hababka wax-soo-saarku waa: (1) qulqulka hawada ee fiilaha kaarboonka ee shabagga gelaya ka dib marka la isku duro;(2) Kaarboonaynta xariirta hore ee oksayjiinaysan;(3) Preoxidation iyo carbonization of polyacrylonitrile fiber la dareemay.Waxa loo isticmaalaa sida walxaha dahaarka foornooyinka faakuumka iyo foornooyinka gaasta aan shaqaynayn, gaaska kulul ama dareeraha iyo filtarrada birta dhalaalaysa, elektrodes unug shidaal dalool leh, qaadeyaasha kicinta, dahaarka isku dhafan ee weelasha u adkaysta daxalka iyo walxaha isku dhafan.
