Ko te Bitumen (te tito: asphaltene me te kapia) kua roa e aro nui ana ki te rangahau me te whakawhanaketanga o nga taika bitumen (te tito: asphaltene me te kapia) kia pai ake ai to mohio ki a maatau taika bitumen (tito: asphaltene me te resin). Asphaltene and resin) taika, ma o matou kaimahi hangarau e whakamarama ki a koe. E whakapono ana ahau he pai ki a koe kia mohio koe ki te hua.
Bitumen (composition: assphaltene and resin) tank I roto i te bitumen (composition: asphaltene and resin)-pūnaha whakahaere wai, ka neke te hanganga ngota o te whakakoha bitumen i waenganui i te bitumen me te wharangi wai, a ko te roopu whakakino wai o tona hanganga rapoi he kua whakaemihia i runga i te Ko te paparanga mata o te bitumen kei roto nga utu kino, i te wa e uru ana nga roopu hydrophilic ki te wahanga wai. Na ka honoa nga matūriki bitumen me te wai, ka whakaiti i te maataki o te mata i waenga i a raatau (whakamaramatanga: ko te kaha taraiwa tahi i te wa e pa ana nga taonga ki te kaha tensile). I tua atu, na te mea kei roto i nga matūriki bitumen te utu kino me te taupatupatu tetahi ki tetahi, e kore ai e kohi tetahi ki tetahi, ka taea e te emulsion bitumen te pupuri i tetahi taumata o te rite me te pumau (whakapuaki: pumau me te pumau; kaore he huringa). Ko nga ahuatanga o te utu kino ka whakatauhia e te utu kino o te roopu hydrophobic o te whakaemulsifier bitumen, tetahi waahanga ranei o te mekameka waiwaro. Mēnā he tōraro, kei roto i ngā matūriki bitumen he utu tōraro, ā, ko te whakaehunga ka puta he whakaehunga bitumen cationic. Engari, he whakaehunga bitumen cationic. Mēnā he utu tōraro me te utu pai o ngā matūriki bitumen, he whakaehunga bitumen zwitterionic te whakaehunga; i tua atu, he wai bitumen kore katote ano.
