Inqubo yokukhiqiza ihlanganisa: izinga lokushisa lokushisa kwetiyela nesisombululo sensipho, ukulungiswa kwenani le-pH yesisombululo sensipho, nokulawula izinga lokugeleza kwepayipi ngalinye ngesikhathi sokukhiqiza.
(1) Ukushisa kokushisa kwetiyela nesisombululo sensipho
Ibitumen idinga izinga lokushisa eliphezulu ukuze ifinyelele isimo esihle sokugeleza. Ukuhlakazwa kwe-emulsifier emanzini, ukwanda komsebenzi wesisombululo sensipho ye-emulsifier, kanye nokwehliswa kokungezwani kobuso bebitumen yamanzi kudinga isisombululo sensipho ukuthi sibe ezingeni lokushisa elithile. Ngesikhathi esifanayo, izinga lokushisa letiyela elifakwe emulsified ngemva kokukhiqizwa alikwazi ukuba ngaphezu kuka-100 ℃, ngaphandle kwalokho lizobangela ukubila kwamanzi. Uma kucatshangelwa lezi zici, izinga lokushisa lokushisisa itiyela likhethwa ukuthi libe ngu-120 ~ 140℃, izinga lokushisa lesisombululo sensipho lingu-55~75℃, futhi izinga lokushisa elifakwe emulsified bitumen alikho ngaphezu kuka-85℃.
(2) Ukulungiswa kwenani le-pH lesisombululo sensipho
I-emulsifier ngokwayo ine-acidity ethile kanye ne-alkalinity ngenxa yesakhiwo sayo samakhemikhali. Ama-emulsifiers e-ionic ancibilika emanzini ukuze enze isisombululo sensipho. Inani le-pH lithinta umsebenzi we-emulsifier. Ukulungisa inani le-pH elifanele kuthuthukisa umsebenzi wesisombululo sensipho. Amanye ama-emulsifiers awakwazi ukuncibilika ngaphandle kokulungisa inani le-pH lesisombululo sensipho. I-Acidity ithuthukisa umsebenzi wama-emulsifiers we-cationic, i-alkalinity ithuthukisa umsebenzi wama-anionic emulsifiers, futhi umsebenzi wama-nonionic emulsifiers awuhlangene nakancane nevelu ye-pH. Uma usebenzisa ama-emulsifiers, inani le-pH kufanele lilungiswe ngokuya ngemiyalelo ethile yomkhiqizo. Ama-asidi nama-alkali asetshenziswa kakhulu yilawa: i-hydrochloric acid, i-nitric acid, i-formic acid, i-acetic acid, i-sodium hydroxide, i-soda ash, nengilazi yamanzi.
(3) Ukulawulwa kokugeleza kwamapayipi
Ukugeleza kwepayipi letiyela nesisombululo sensipho kunquma okuqukethwe kwebitumen emkhiqizweni webitumen emulsified. Ngemuva kokuthi isisetshenziswa se-emulsification silungisiwe, umthamo wokukhiqiza ulungiswa ngokuyisisekelo. Ukugeleza kwepayipi ngalinye kufanele kubalwe futhi kulungiswe ngokuhambisana nohlobo lwebitumen e-emulsified ekhiqizwayo. Kufanele kuqashelwe ukuthi isamba sokugeleza kwepayipi ngalinye kufanele silingane nevolumu yokukhiqiza itiyela e-emulsified.
