Mune emulsified asphalt, pH kukosha zvakare ine imwe pesvedzero pane demulsification rate. Usati wadzidza pesvedzero yepH pane demulsification rate ye emulsified asphalt, demulsification nzira dzeanionic emulsified asphalt uye cationic emulsified asphalt inotsanangurwa zvakateerana.

Cationic emulsified asphalt demulsification inovimba nechaji yakanaka yeatomu yenitrogen muboka reamine muchimiro chemakemikari yeasphalt emulsifier kuti ive hukama nechaji isina kunaka yeaggregate. Nokudaro, mvura iri mu emulsified asphalt inosvinwa kunze uye inoputika. Iyo demulsification ye emulsified asphalt inopedzwa. Nekuti kuiswa kwepH-adjusting acid kunokonzeresa kuwedzera kwechaji yakanaka, kunonotsa kusanganiswa kwechaji yakanaka inotakurwa neasphalt emulsifier uye aggregate. Naizvozvo, iyo pH ye cationic emulsified asphalt ichakanganisa chiyero che demulsification.
Kupomerwa kwakashata kweanionic emulsifier pachayo muanionic emulsified asphalt inopindirana pamwe chete nemhosva yakaipa yeaggregate. Iyo demulsification yeanionic emulsified asphalt inotsamira pakunamira kweasphalt pachayo kune aggregate kusvina kunze kwemvura. Anionic asphalt emulsifiers inowanzovimba nemaatomu eokisijeni kuti ave hydrophilic, uye maatomu eokisijeni anoumba mabhondi ehydrogen nemvura, zvichiita kuti kubuda kwemvura kunonoke. Iyo hydrogen bonding effect inowedzerwa pasi peacidic mamiriro uye inoshaikwa pasi pemamiriro ealkaline. Naizvozvo, iyo yakakwirira pH, inononoka demulsification mwero muanionic emulsified asphalt.
