Hauv emulsified asphalt, pH nqi tseem muaj qee yam cuam tshuam rau cov demulsification tus nqi. Ua ntej kev kawm txog qhov cuam tshuam ntawm PH ntawm kev rhuav tshem tus nqi ntawm emulsified aschhalify ntawm anionic emulsified asulhalt yog piav qhia rau feem.

Cationic emulsified kev phem kev sib raug zoo ntawm tus nqi zoo ntawm cov qauv amine ntawm cov qauv amine ntawm cov neeg asphaltifier ua rau muaj kev sib sau ua ke ntawm kev sib sau ua ke. Yog li, cov dej hauv emulsified asphalt yog nyem tawm thiab volatilized. Qhov demulsification ntawm emulsified asphalt ua tiav. Vim tias cov lus qhia ntawm PH-kho cov kua qaub yuav ua rau muaj kev nce ntxiv, nws ua rau kev sib xyaw ntawm tus nqi txhawb nqa los ntawm kev sib sau ua ke ntawm kev txhawb nqa thiab ua ke. Yog li ntawd, cov phericic emulsified yuav cuam tshuam rau tus mob phev.
Tus nqi tsis zoo ntawm anionic emulsifier nws tus kheej hauv anionic emulsified ashrhalt yog kev sib cav sib ceg yog kev sib sau ua ke ntawm kev sib sau ua ke. Qhov demulsification ntawm anionic emulsified ashrhalt tso siab rau ntawm cov nplaum ntawm cov asphalt nws tus kheej rau kev sib sau ua ke kom nyem cov dej. Anionic Asphaltifiers feem ntau cia siab rau oxygen atoms los ua hydropen khi nrog dej, ua rau lub evaporation dej kom qeeb. Cov nyhoo hydrogening cov nyhuv yog txhim kho nyob rau hauv acidic tej yam kev mob thiab tsis muaj zog nyob hauv cov xwm txheej alkaline. Yog li ntawd, qhov siab dua pH, qeeb qeeb thaum rhuav tshem tus nqi hauv anionic emulsified ashrhalt.
