Tarihin ci gaban 4.0mm columnar aiki coal: Coal columnar aiki coal ne sosai kyakkyawan adsorbent, shi ne da amfani da katako coal, daban-daban 'ya'yan itace shells da kuma ingancin kwal, da dai sauransu a matsayin albarkatun kasa, ta hanyar jiki da sinadarai hanyoyin karya albarkatun kasa, surscreening, catalyst kunnawa, wanke, bushewa da kuma screening da sauransu jerin tsari sarrafawa. Coal columnar active carbon sunan ya fara ne daga Yaƙin Duniya na I.

A shekara ta 1915, a lokacin Yaƙin Duniya na farko, sojojin Jamus sun yi amfani da sabon makami mai ban tsoro a kan sojojin Ingila da Faransa - kilo 180,000 na gas mai guba na sinadarai. Sojojin Ingila da Faransa dubu biyar suka mutu a wurin, kuma dubu goma sha biyar suka yi rauni. Akwai "mako" zai ƙirƙiri "gargajiya", kuma gas mai guba zai ƙirƙiri makamai masu rigakafi. A cikin makonni biyu bayan haka, masana kimiyyar soja sun ƙirƙiri makamai don kare gubar chlorine, kuma sun aika da murfin rufe fuska na musamman ga kowane soja na gaba, wanda aka nutse shi da auduga mai maganin sodium sulfate da sodium carbonate. Dukkanin magungunan suna da ayyukan kawar da chlorine kuma suna iya taka rawar karewa. Amma idan abokan gaba suka canza zuwa gas na biyu, wannan mask ba zai iya yin wani abu ba. Gaskiya ma, kasa da shekara guda bayan haka, bangarorin biyu sun yi amfani da nau'ikan gas masu guba daban-daban, gami da gas mai guba da hydrogen cyanide da aka sani a yau. Don haka dole ne a sami wani abu da zai sa kowane gas ya rasa guba. Masana kimiyya sun gano wannan magunguna a ƙarshen 1915. Yana da 4.0mm columnar aiki carbon.

A shekara ta 1917, an sanya carbon mai aiki a cikin masks na gas na bangarorin da ke yaƙi, wanda ya rage haɗarin gas ga sojojin da ke yaƙi. A lokacin yakin duniya na biyu, Jamus ta fara amfani da gas mai guba don haifar da yaƙin gas mai guba, mutane sun fara neman hanyoyin kauce wa gas mai guba, kuma kwal mai inganci yana amfani da shi sosai saboda ingancin hana gas mai guba. Tare da zuwan yakin sanyi na duniya, kwal mai aiki ya shiga rayuwar mutane na yau da kullun daga yaƙi, koyaushe shi ne babban aikin masana'antun sarrafa ruwa, asibitoci da sauransu.

A shekara ta 2002, an haife Black Diamond Coal Block-shaped Seamless Activated Coal, bayyanarsa ta cika wannan blank na duniya na aikin kwal, ya sa amfani da aikin kwal ya zama babban mataki, Black Diamond Coal yana amfani da manyan fasahohin ƙirƙirar duniya, yayin da yake kiyaye babban darajar absorbance, Black Diamond Coal ya zama kayan aiki masu ado, ya sa gargajiya da kuma daɗin daɗi ya nuna, a lokaci guda, kuma ya sa Black Diamond Coal ya zama mai amfani da sararin samaniya a gida, a cikin mota, ofisoshi, otal-otal, wuraren nishaɗi da sauransu.

A shekarar 2003, kwal mai aiki ya zama babban zaɓi ga ma'aikatan kiwon lafiya har ma da jama'a na yau da kullun don kare kwal mai aiki saboda ingancinsa. Amma 4.0mm ginshike aiki carbon ya kasance foda ko granular, saboda shi ba sauki kiyaye, gajeren lokaci, sauki gurɓataccen abubuwa da sauransu domin iyakance shi ne mafi fadi amfani, aiki carbon fasaha ya kasance a duniya babban matsala, kuma a matsayin da ya kasance a kasar Sin, mu sake tafiya a gaba.
