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℃), Baaxadda gaarka ah ee dusha sare waxay ahayd> 1.5m2/g, nuxurka dambaska wuxuu ka yaraa 0.3%, maadada baaruuddu waxay ka yaraatay 0.03%.
Fiber kaarboon firfircoon (ACF) waa nooc cusub oo wax ku ool ah oo wax ku ool ah oo ka baxsan kaarboonka firfircoon (GAC), waana badeeco cusub. Waxay leedahay qaab-dhismeedka microporous si heer sare ah loo horumariyay, awoodda xayeysiinta weyn, xawaaraha desorption degdega ah, saamaynta nadiifinta wanaagsan, waxaa lagu farsamayn karaa noocyo kala duwan oo tilmaamo ah oo dareemay, xariir, maro. Alaabta ayaa leh sifooyinka kulaylka, caabbinta aashitada 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 hawo-mareenka 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, gaas kulul ama dareere iyo filtarrada birta dhalaalaysa, elektrodes unug shidaal dalool leh, sidayaal kicin, dahaarka isku dhafan ee weelasha u adkaysta daxalka iyo walxaha isku dhafan.
