Mfundo ya kuyamwa kwa mpweya wopangidwa

1. Kutengera kapangidwe kake ka pore

Kaboni yogwira ntchito ndi mtundu wa zinthu za kaboni zazing'ono zomwe zimapangidwa makamaka ndi zinthu zakuda, kapangidwe ka ma pore amkati, malo akuluakulu apadera komanso mphamvu yamphamvu yothira madzi. Zinthu za kaboni zogwira ntchito zimakhala ndi ma pore ambiri osawoneka, ma pore a kaboni ogwiritsiridwa ntchito a 1 g, adzakulitsidwa pambuyo poti malo a pamwamba atha kukhala 800-1500 square metres, pogwiritsa ntchito. Ndiko kuti, malo amkati mwa ma pore mu tinthu ta kaboni yogwira ntchito kukula kwa njere ya mpunga kungakhale kukula kwa chipinda chochezera. Ndi izi zopangidwa kwambiri, monga kapangidwe ka ma pore a capillary a anthu, kotero kuti kaboni yogwira ntchito imakhala ndi ntchito yabwino yothira madzi.

Kuthira mpweya wopangidwa ndi mpweya (Activated Carbon Adsorption) ndi njira yopezera mpweya kapena madzi pamwamba pa mpweya wopangidwa ndi mpweya (activated carbon), chinthu cholimba chosagwira ntchito. Njira imeneyi imagwiritsidwa ntchito kuchotsa zinthu zosiyanasiyana zodetsa zomwe zimasungunuka m'madzi, mpweya, ndi mitsinje ya mpweya.

2. Mphamvu ya kuyamwa pakati pa mamolekyulu

Amadziwikanso kuti "van der Waals gravity". Ngakhale kuti liwiro la kayendedwe ka mamolekyu limakhudzidwa ndi kutentha ndi zinthu, nthawi zonse limayenda m'malo ozungulira. Mpweya woyambitsa chifukwa cha kukopana pakati pa mamolekyu, pamene molekyulu idayambitsidwa, dzenje lamkati la kaboni limagwidwa mu pore yamkati ya kaboni yoyambitsidwa, chifukwa cha kukopana pakati pa mamolekyu, zidzapangitsa kuti mamolekyu ambiri akopeke, mpaka kudzaza pore yamkati ya kaboni yoyambitsidwa.

Mfundo yokhudza kulowetsedwa kwa mpweya wopangidwa ndi activated carbon: Yopangidwa mu tinthu tating'onoting'ono pamwamba pa tinthu tating'onoting'ono imayendetsa kuchuluka kwa pamwamba, kenako zodetsa za zinthu zachilengedwe zomwe zimalowetsedwa ku tinthu ta kaboni wopangidwa ndi activated carbon, zomwe zimapangitsa kuti kulowetsedwa kwa mpweya kukhale kwakukulu. Koma pakapita nthawi, mphamvu yolowetsedwa kwa mpweya wopangidwa ndi activated carbon idzachepa kwambiri, ndipo mphamvu yolowetsedwa imachepanso. Ngati madzi a m'madzi aku aquarium ali ndi matope ambiri, kuchuluka kwa organic m'madzi, mpweya wopangidwa ndi activated kaboni posachedwa udzatayika ntchito yosefera. Mpweya wopangidwa ndi activated kaboni uyenera kutsukidwa nthawi zonse kapena kusinthidwa.
