Ibitumen (ukwakheka: i-asphaltene ne-resin) abakhiqizi bokukhiqiza amathangi kudala begxile ocwaningweni nasekuthuthukisweni kwethangi lekhwalithi ephezulu (ukwakheka: i-asphaltene ne-resin) ukukusiza ukuthi uqonde kangcono amathangi ethu (ukwakheka: i-asphaltene ne-resin). Amathangi e-asphaltene ne-resin, vumela abasebenzi bethu bezobuchwepheshe bakuchazele. Ngikholwa ukuthi kuzosiza ukuthi uqonde umkhiqizo.
Ibitumene (ukwakheka: i-asphaltene ne-resin) ithangi Ethangini (ukwakheka: i-asphaltene ne-resin) -uhlelo lokuphatha amanzi, ukwakheka kwamangqamuzana e-emulsifier yebitumen kuhamba phakathi kwebitumen namakhasi amanzi, futhi iqembu elizonda amanzi lesakhiwo salo samangqamuzana i-adsorbed on the Ungqimba olungaphezulu lwebitumen luqukethe amacala amabi, kuyilapho amaqembu e-hydrophilic engena esigabeni samanzi. Khona-ke izinhlayiya zebitumen namanzi ziyaxhunywa, kunciphisa ukungezwani kwendawo phakathi kwazo (incazelo: amandla okushayela okuhlangene lapho izinto zingaphansi kwamandla okuqina). Ngaphezu kwalokho, ngenxa yokuthi izinhlayiya zebitumen ziqukethe ukushaja okungalungile okufanayo nokungqubuzana komunye nomunye, ukuvimbela ukuba bahlangane ndawonye, ​​i-emulsion yebitumen ingagcina izinga elithile lokufana nokuzinza (inkulumo: iqinile futhi iqinile; akukho shintsho). Izici zokushaja okungekuhle zinqunywa ukushajwa okungekuhle kweqembu le-hydrophobic le-bitumen emulsifier noma ingxenye yeketango le-hydrocarbon. Uma i-negative, izinhlayiya zebitumen ziqukethe amacala angalungile, futhi i-emulsion ephumela i-emulsion ye-bitumen ye-cationic. Ngokuphambene nalokho, i-emulsion yebitumen ye-cationic. Uma izinhlayiya zebitumen zinokushaja okungalungile nokuhle, i-emulsion iyi-emulsion yebitumen ye-zwitterionic; ngaphezu kwalokho, kukhona noketshezi lwebitumen olungezona i-ionic.
