Shaandheeye Fiber Kaarboon Firfircoon oo ku jira Daaweynta Biyaha
Astaamaha Alaabta
Faybarka kaarboonka ee firfircoon (ACF) waa nooc ka mid ah walxaha nanometer-ka ee aan organic ahayn oo ka kooban curiyayaasha kaarboonka oo ay sameeyeen tiknoolajiyada kaarboonka iyo tiknoolajiyada kaarboonka ee firfircoon. Badeecadeennu waxay leedahay bedka dusha sare ee gaarka ah iyo noocyo kala duwan oo hiddo-wadeyaal firfircoon. Markaa waxay leedahay waxqabad nuugis oo aad u fiican waana badeecad ilaalin deegaan oo farsamo sare leh, waxqabad sare leh, qiimo sare leh, oo faa'iido sare leh. Waa jiilka saddexaad ee alaabada kaarboonka firfircoon ee fibrous ka dib kaarboonka firfircoon ee budada ah iyo granular. Waxaa lagu ammaanaa inay tahay walaxda ugu sarreysa ee ilaalinta deegaanka ee 21stqarni. Faybarka kaarboonka ee firfircoon waxaa loo isticmaali karaa soo kabashada dareeraha dabiiciga ah, nadiifinta biyaha, nadiifinta hawada, daaweynta biyaha wasakhda ah, baytariyada tamarta sare leh, aaladaha ka hortagga fayraska, daryeelka caafimaadka, caafimaadka hooyada iyo ilmaha, iwm. Faybarka kaarboonka ee firfircoon wuxuu leeyahay awood weyn oo lagu horumarin karo.
Cilmi-baarista, soo saarista iyo adeegsiga fiber-ka kaarboon ee la shiiday ee Shiinaha waxay leedahay taariikh ka badan 40 sano, waxayna ahaayeen natiijooyin wanaagsan.

Tilmaamaha Alaabta
(1) Baaxadda dusha sare ee gaarka ah oo weyn (BET): waxaa jira nano-pore badan, oo ka badan 98%. Markaa, waxay leedahay bedka dusha sare ee gaarka ah oo aad u weyn (Guud ahaan uo ilaa 1000-2000m2/g, ama xitaa in ka badan 2000m2/g). Awooddeeda nuugista waa 5-10 jeer ka badan kaarboon firfircoon.
(2) Xawaaraha nuugista degdega ah: nuugista gaasaska waxay gaari kartaa dheelitirka nuugista tobanaan daqiiqo gudahood, taasoo ah 2-3 cabir oo cabbirkeedu ka sarreeyo GAC. nuugista gaasaska waa mid dhakhso badan waxaana dib loo isticmaali karaa boqolaal jeer. Waxaa gebi ahaanba laga saari karaa iyadoo la kululeynayo 10-30 daqiiqo iyadoo la isticmaalayo uumi ama hawo kulul oo ah 10-150℃.
(3) Waxtarka nuugista sare: waxay nuugi kartaa oo shaandheyn kartaa gaaska sunta ah, gaaska qiiqa (sida NO, NO2, SO2, H2S, NH3, CO, CO2 iwm.), fetor iyo urta jidhka ee hawada ku jirta. Awoodda nuugista waa 10-20 jeer ka badan kaarboon firfircoon.
(4) Kala duwanaanshaha nuugista badan: awoodda nuugista ee ayoonnada birta aan organic ahayn, kuwa organic iyo kuwa culus ee ku jira xalka biyaha waa 5-6 jeer ka sarreeya kan kaarboon firfircoon. Waxa kale oo ay leedahay awood nuugis oo wanaagsan oo loogu talagalay noolaha yaryar iyo bakteeriyada, sida rata nuugista ee Escherichia coli waxay gaari kartaa 94-99%.
(5) Iska caabinta heerkulka sare: maadaama kaarboonku uu yahay mid aad u sarreeya ilaa 95%, waxaa si caadi ah loo isticmaali karaa ka hooseeya 400℃. Waxay leedahay iska caabin heerkul sare oo ku jirta gaasaska aan firfircoonayn ee ka sarreeya 1000℃ iyo barta shidista hawada ee 500℃.
(6) Iska caabin xooggan oo aashitada iyo alkali ah: Korantada oo wanaagsan iyo xasillooni kiimiko.
