Me ka sani game da kunna carbon?
Me ake nufi da kunna carbon?
Carbon da aka kunna abu ne na halitta wanda aka sarrafa wanda ke da yawan sinadarin carbon. Misali, kwal, itace ko kwakwa cikakke ne ga wannan. Samfurin da aka samar yana da babban porosity kuma yana iya shanye ƙwayoyin gurɓatattun abubuwa ya kama su, ta haka yana tsarkake iska, iskar gas da ruwa.
Waɗanne nau'ikan carbon da aka kunna za a iya samu?
Ana iya ƙera carbon mai aiki a cikin nau'ikan granular, pelletized da powdered. Ana ayyana girma dabam-dabam don aikace-aikace daban-daban. Misali, a cikin maganin iska ko iskar gas, ƙuntatawa ga kwarara shine shigo da kaya, don haka ana amfani da ƙananan barbashi don rage asarar matsi. A cikin maganin ruwa, inda tsarin cirewa yake da jinkiri, to ana amfani da ƙananan barbashi don inganta saurin, ko motsi, na tsarin tsarkakewa.
Ta yaya carbon da aka kunna yake aiki?
Carbon da aka kunna yana aiki ta hanyar shaƙa. Wannan shine jan hankalin kwayar halitta zuwa babban saman carbon ɗin ta hanyar ƙarfi mai rauni, wanda aka sani da ƙarfin London.

Wannan na iya zama da amfani domin ana iya amfani da carbon da aka kunna don tattara abu a samansa wanda daga baya za a iya cire shi kuma a dawo da shi. Amfani da carbon da aka kunna don dawo da zinare misali ne na gama gari na wannan.
A wasu lokuta, ana amfani da sinadarin sinadarai wajen magance gurɓatattun abubuwa, kuma a wannan yanayin, ba a sake samun sinadarin da ke haifar da gurɓataccen iska ba.
