Asphalt emulsified, qiimaha pH waxa kale oo uu saamayn gaar ah ku leeyahay heerka demulsification. Ka hor inta aan la baranin saamaynta pH ee heerka demulsification of emulsified asphalt, hababka demulsification ee anionic emulsified asphalt iyo cationic emulsified asphalt ayaa la sharaxay siday u kala horreeyaan.

Demulsification Asphalt Cationic emulsified wuxuu ku tiirsan yahay kharashka togan ee atamka nitrogen ee kooxda aminiga ee qaab dhismeedka kiimikaad ee emulsifier-ga si uu ula xidhiidho dallaca taban ee wadarta. Haddaba, biyaha ku jira daamurka emulsified ayaa la tuujiyey oo isbedelay. Burburinta daamurka emulsified waa la dhammaystiray. Sababtoo ah soo bandhigida aashitada- hagaajinta pH waxay sababi doontaa kororka kharashka togan, waxay hoos u dhigtaa isku darka kharashka togan ee uu qaado emulsifier-ka asphalt iyo isku-darka. Sidaa darteed, pH ee asphalt emulsified cationic waxay saameyn doontaa heerka demulsification.
Kharashka taban ee emulsifier-ka anionic laftiisa ee ku jira asphalt emulsified anionic ayaa si wada jir ah u gaar ah dallaca taban ee wadarta guud. Burburinta asphalt-ka anionic emulsified waxay ku tiirsan tahay ku-xidhka asphaltka laftiisa isku-darka si loo tuujiyo biyaha. Anionic asphalt emulsifiers guud ahaan waxay ku tiirsan yihiin atamka oksijiinta si ay u noqdaan hydrophilic, iyo atamka oksijiinta waxay sameeyaan curaarta hydrogen iyo biyaha, taasoo keenta uumiga biyaha inuu hoos u dhaco. Saamaynta isku xidhka hydrogen waxaa lagu wanaajiyey xaaladaha acidic iyo daciifinta hoos xaaladaha alkaline. Sidaa darteed, mar kasta oo pH-gu sareeyo, waxaa sii yaraanaya heerka demulsification ee asphalt-ka anionic emulsified.
