Matatar carbon da aka kunna

Siffar shaye-shayen carbon da aka kunna ta samo asali ne daga tsarin ramukansa masu tasowa. Binciken diffraction na X-ray ya nuna cewa takamaiman yankin saman carbon mai inganci zai iya kaiwa har zuwa 1,000-3,000m²/g, gami da ƙananan ramuka masu diamita na 0.8-2nm, mesopores masu diamita na 2-50nm, da macropores masu diamita fiye da 50nm. Wannan tsarin ramuka masu matakai da yawa zai iya riƙe abubuwa masu rai, ragowar chlorine da wasu ions na ƙarfe masu nauyi tare da nauyin kwayoyin halitta na 60-300 daltons ta hanyar haɗin gwiwar ƙarfin van der Waals da haɗin sinadarai. Musamman a cikin maganin mahaɗan kwayoyin halitta masu canzawa (VOCs), ƙarfin shaye-shaye masu ƙarfi ga gurɓatattun abubuwa kamar benzene da formaldehyde na iya kaiwa 200-500mg/g.

An tsara matatun carbon da aka kunna na zamani tare da tsarin haɗin gwiwa wanda ke ɗauke da layin kafin a yi magani (auduga PP), babban layin shaye-shaye (auduga mai aiki da foda), da kuma layin bayan magani (auduga mai hana ƙwayoyin cuta). Sassan masana'antu galibi suna ɗaukar ƙirar kwararar radial, don haka lokacin hulɗa ta hanyar gadon carbon da aka kunna 0.5-2mm ana kiyaye shi a cikin daƙiƙa 5-15, kuma ana sarrafa raguwar matsin lamba a 0.05-0.2 MPa. Shaƙar sinadarai na takamaiman gurɓatattun abubuwa (misali, hydrogen sulphide, tururin mercury) za a iya inganta shi ta hanyar fasahar gyara saman (misali, shigar da ƙarfe mai canzawa), kuma ana iya ƙara ingancin shaye-shaye na zaɓi da fiye da 40%.
