Dab tsi yuav tsum tau them nyiaj rau thaum lub emulsified bitumen cov khoom siv tau ua haujlwm?
Raws li peb txhua tus paub, lub nro nro ntawm asphalt thiab dej sib txawv heev. Nyob rau hauv chav tsev kub los yog kub siab, sib tawm sib cais yuav tshwm sim. Cov cuab yeej siv emulsified siv qib siab ceev, cuam tshuam thiab lwm txoj kev tsav tsheb tawg paj, yog li nws lub microns, tawg rau hauv cov dej hauv nruab nrab muaj surfactants. Txij li thaum emulsifier tuaj yeem raug adsorbed nyob rau saum npoo ntawm emulsified bitumen cov cuab yeej, cov kev cuam tshuam interfacial ntawm asphalt thiab dej yog txo. Raws li qhov tshwm sim, cov asphaltalal hais ua ib qho kev cuam tshuam ruaj khov hauv dej, yog li sib sau cov khoom siv emulsified.
