Bitumen (kuumbwa: asphaltene uye resin) vagadziri vekugadzira matangi vagara vachitarisa kutsvagisa nekuvandudzwa kwematangi emhando yepamusoro bhitumeni (kuumbwa: asphaltene uye resin) kuti ikubatsire kunzwisisa zviri nani bhitumini yedu (kuumbwa: asphaltene uye resin) matangi. Asphaltene uye resin) matangi, rega vashandi vedu vehunyanzvi vakutsanangurire. Ndinotenda kuti zvichabatsira kuti iwe unzwisise chigadzirwa.
Bhitumeni (kuumbwa: asphaltene neresin) tangi Mubhitumeni (kuumbwa: asphaltene uye resin) -mvura yekugadzirisa system, chimiro chemomecular yebhitumeni emulsifier inofamba pakati pebhitumeni nemapeji emvura, uye boka rinovenga mvura remamorekuru aro. adsorbed on the The surface layer of bitumen ine negative charges, nepo hydrophilic groups ichipinda muchikamu chemvura. Zvadaro zvimedu zvebhitumini nemvura zvakabatana, zvichideredza kusawirirana kwepamusoro pakati pazvo (tsanangudzo: iyo mutual driving force kana zvinhu zvichiiswa pasi pesimba remagetsi). Mukuwedzera, nokuti bhitumini particles ine mhosva yakashata yakafanana uye kupesana kune mumwe nemumwe, kudzivirira kuti vasaungana pamwe chete, emulsion yebhitumen inogona kuchengetedza imwe nhanho yehutano uye kugadzikana (kutaura: kusimba uye kugadzikana; hapana shanduko). Hunhu hwekuchaja kwakashata hunotarirwa nechaji isina kunaka yeboka rehydrophobic yebhitumeni emulsifier kana chikamu cheketani yehydrocarbon. Kana zvisina kunaka, zvimedu zvebhitumini zvine mhosva dzisina kunaka, uye emulsion inoguma inonzi cationic bitumen emulsion. Pane zvinopesana, iyo inonzi cationic bitumen emulsion. Kana zvimedu zvebhitumini zvine zvose zvakaipa uye zvakanaka, emulsion inonzi zwitterionic bitumen emulsion; uyezve, kune zvakare asiri-ionic bhitumeni zvinwiwa.
