Kutora polyacrylonitrile yakavakirwa kabhoni yakanzwa semuenzaniso, iyo nzvimbo uremu i500g/m2 uye 1000g/m2, iyo longitudinal uye inochinjika simba (N/mm2) ndeye 0.12, 0.16, 0.10, 0.12, iyo yekutyora elongation i3%, 4%, 18%, 16%, uye resistivity (Ω·mm) ari 4-6, 3.5-5.5 uye 7-9, 6-8, zvichiteerana. Iyo yekupisa conductivity yaive 0.06W/(m·K)(25℃), nzvimbo chaiyo yaiva> 1.5m2/g, madota akanga ari pasi pe0.3%, uye sulfuri yakasvibiswa yakanga iri pasi pe0.03%.
Activated carbon fiber (ACF) rudzi rutsva rwepamusoro-soro adsorption zvinhu zvinopfuura activated carbon (GAC), uye chigadzirwa chechizvarwa chitsva. Iyo ine yakanyanya kugadziridzwa microporous chimiro, yakakura adsorption kugona, inokurumidza desorption kumhanya, yakanaka yekunatsa maitiro, inogona kugadziriswa kuita akasiyana siyana ekunzwa, sirika, machira. Chigadzirwa chacho chine maitiro ekupisa, acid uye alkali resistance.
Maitiro maitiro:
Iyo adsorption kugona kweCOD, BOD nemafuta mune aqueous solution yakakwira zvakanyanya kupfuura iyo yeGAC. Iyo adsorption kuramba idiki, iyo yekumhanyisa inokurumidza, iyo desorption inokurumidza uye yakakwana.
kugadzirira:
Nzira dzekugadzira ndeidzi: (1) kabhoni filament mhepo inoyerera mumambure mushure mekuda; (2) Carbonization ye pre-oxygenated silk yakanzwa; (3) Preoxidation uye carbonization ye polyacrylonitrile fiber yakanzwa. Inoshandiswa semidziyo yekudzivirira yevacuum furnaces uye inert gasi mafirita, gasi rinopisa kana mvura uye yakanyungudutswa mafirita esimbi, porous fuel cell electrodes, catalyst carriers, composite linings ye corrosion resistant midziyo uye composite zvinhu.
