ʻO ka lawe ʻana i ka carbon polyacrylonitrile ma ke ʻano he laʻana, ʻo ke kaupaona ʻana he 500g/m2 a me 1000g/m2, ʻo ka longitudinal a me ka ikaika transverse (N/mm2) he 0.12, 0.16, 0.10, 0.12, ʻo ka elongation haʻihaʻi he 3%, 4%, 18%, 16%, a me ka resistivity (Ω·mm) he 4-6, 3.5-5.5 a me 7-9, 6-8. He 0.06W/(m·K)(25℃), 'o ka 'ilikai kiko'ī he > 1.5m2/g, ka lehu ma lalo o 0.3%, a me ka sulfur ma lalo o 0.03%.
ʻO ka fiber carbon activated (ACF) he ʻano hou o ka mea hoʻohana kiʻekiʻe adsorption ma mua o ka carbon activated (GAC), a he huahana hanauna hou ia. Loaʻa iā ia kahi hoʻolālā microporous i hoʻomohala nui ʻia, ka mana adsorption nui, ka wikiwiki desorption wikiwiki, ka hopena hoʻomaʻemaʻe maikaʻi, hiki ke hana ʻia i nā ʻano kikoʻī o ka manaʻo, siliki, lole. Loaʻa i ka huahana nā hiʻohiʻona o ka wela, ka waikawa a me ka pale alkali.
Nā ʻano hana:
ʻOi aku ka kiʻekiʻe o ka mana adsorption o COD, BOD a me ka aila i loko o ka wai wai ma mua o ka GAC. He liʻiliʻi ke kūpaʻa adsorption, wikiwiki ka wikiwiki, wikiwiki a piha ka desorption.
hoomakaukau:
ʻO nā ʻano hana: (1) kahe ka ea filament carbon i ka ʻupena ma hope o ka pono ʻana; (2) Carbonization o pre-oxygenated siliki manaʻo; (3) ʻO ka preoxidation a me ka carbonization o ka polyacrylonitrile fiber manaʻo. Hoʻohana ʻia e like me nā mea insulation no nā kapuahi a me nā kapuahi inert, ke kinoea wela a i ʻole ka wai a me nā kānana metala hoʻoheheʻe ʻia, nā electrodes wahie porous, nā mea lawe catalyst, nā linings composite no nā moku kū i ka corrosion a me nā mea hana.
