Daawaynta kulaylka ee shubka birta kaarboon

Hababka daawaynta kulaylka sida caadiga ah loo isticmaalo shubida birta kaarboon waa: nusqaan, caadi ka dhigid ama caadi ka dhigid + xanaaq. Saamaynta saddexdan hababka daaweynta kulaylka ee sifooyinka farsamada ee birta kaarboonka ah ayaa lagu muujiyay sawirka hoose.

Qalabka farsamada ee birta kabka ee caadiga ah ayaa waxyar ka sarreeya kuwa birta shubka ah ee la shiiday. Maaddaama heerka qaboojinta hoos u dhigista inta lagu jiro isbeddelka qaabdhismeedka uu yahay mid aad u weyn, qallafsanaantu waxay noqon doontaa mid sare, iyo waxqabadkeeda goynta ayaa sidoo kale ka sii fiican.

Ku shubista birta kaarboon ee leh kaarboon sare iyo qaabab isku dhafan, si loo baabi'iyo walbahaarka haraaga oo loo wanaajiyo adkaanta, daaweynta kuleylka ayaa la sameyn karaa ka dib marka la caadiyeeyo. Heerkulka heerkulka guud ahaan waa 550 ℃-650 ℃, ka dibna ku qabooji hawada.

Marka waxa ku jira kaarboonku uu ka sarreeyo 0.35%, qaybaha birta kaarboonka ee la shubay sidoo kale waa la damin karaa oo la xanaaqi karaa (damiyay + heer kul sare). Tuubadaha kaarboonka yar ee birta ah si toos ah ayaa loo demi karaa oo loo xanaaqi karaa sida-kabka; shubista birta kaarboon ee wayn ama qaabaysan waa in la demiyo oo la xanaaqaa ka dib marka la caadiyeeyo.
