Bitumen (kupangidwa: asphaltene ndi utomoni) opanga matanki opangira matanki akhala akuyang'ana kwambiri kafukufuku ndi chitukuko cha matanki apamwamba kwambiri (kupangidwa: asphaltene ndi utomoni) kuti akuthandizeni kumvetsa bwino matanki athu (kupangidwa: asphaltene ndi resin). Matanki a asphaltene ndi resin), lolani akatswiri athu akufotokozereni izi. Ndikukhulupirira kuti zingakhale zothandiza kuti mumvetsetse mankhwalawo.
Bitumeni (kapangidwe: asphaltene ndi utomoni) thanki Mu phula (kapangidwe: asphaltene ndi utomoni) -dongosolo lamadzi loyang'anira madzi, mamolekyu a phula la emulsifier amayenda pakati pa masamba a phula ndi madzi, ndipo gulu lodana ndi madzi la maselo ake ndi adsorbed pa Pamwamba wosanjikiza wa phula muli milandu zoipa, pamene magulu hydrophilic kulowa madzi gawo. Ndiye tinthu tating'onoting'ono ta phula ndi madzi zimalumikizidwa, kuchepetsa kusamvana kwapakati pakati pawo (mafotokozedwe: mphamvu yolumikizirana pamene zinthuzo zimayendetsedwa ndi mphamvu). Komanso, chifukwa phula particles ali chimodzimodzi zoipa mlandu ndi mikangano wina ndi mzake, kuwalepheretsa kusonkhana wina ndi mzake, phula emulsion akhoza kukhala ndi mlingo wina wa kufanana ndi bata (mawu: olimba ndi khola; palibe kusintha). Makhalidwe a ndalama zoipa amatsimikiziridwa ndi mlandu woipa wa gulu la hydrophobic la emulsifier phula kapena gawo la unyolo wa hydrocarbon. Ngati ndi zoipa, ndi phula particles muli zoipa mlandu, ndipo chifukwa emulsion ndi cationic phula emulsion. M'malo mwake, ndi cationic phula emulsion. Ngati phula particles onse zoipa ndi zabwino mlandu, ndi emulsion ndi zwitterionic phula emulsion; kuonjezerapo, palinso zakumwa zopanda ionic phula.
