Koj puas paub ntau npaum li cas txog kev siv cov khoom siv bitumen emulsion? Raws li cov chaw tsim khoom tshwj xeeb hauv kev tsim cov khoom siv asphalt, cov txheej txheem tsim khoom ntawm peb cov khoom siv bitumen emulsion yog dab tsi? Tom ntej no, peb cov neeg ua haujlwm yuav muab cov lus piav qhia luv luv rau koj.

Lub nro nro ntawm bitumen thiab dej nyob rau hauv bitumen emulsion ntau heev, thiab lawv tsis yog miscible nrog txhua lwm yam ntawm ib txwm muaj lossis kub. Txawm li cas los xij, thaum cov khoom siv bitumen emulsion raug rau cov khoom siv xws li kev kub ceev centrifugation, shearing, thiab cuam tshuam, cov nroj tsuag bitumen emulsion hloov mus rau hauv cov khoom uas muaj qhov loj me ntawm 0.1 ~ 5 μm thiab tau tawg mus rau hauv cov dej nruab nrab uas muaj surfactant. Txij li thaum lub emulsifier tuaj yeem coj cov adsorption ntawm qhov chaw ntawm cov khoom siv bitumen emulsion, qhov kev sib tshuam ntawm cov dej thiab cov bitumen raug txo kom tsawg, cia cov bitumen hais los ua ib qho kev ruaj khov dispersion hauv dej. Bitumen emulsion khoom yog cov roj-hauv-dej emulsion. Qhov no dispersion system yog xim av xim av, nrog bitumen raws li lub dispersed theem thiab dej raws li lub nruam theem, thiab muaj fluidity zoo nyob rau hauv chav tsev kub.
Cov saum toj no yog cov ntsiab lus tseem ceeb ntawm bitumen emulsion cog. Yog tias koj xav paub ntau ntxiv txog cov ntaub ntawv zoo siab, thov hu rau peb cov neeg ua haujlwm hauv lub sijhawm.
