Emulsified asphalt yog cov roj-hauv-dej ua kua ua los ntawm asphalt thiab dej nrog surfactant ntxiv los ntawm emulsified asphalt ntau lawm cov khoom. Nws yog kua ntawm chav tsev kub thiab tuaj yeem siv ncaj qha lossis diluted nrog dej. Asphalt yog khoom nyob rau hauv chav tsev kub. Yog tias nws yuav tsum tau siv, nws yuav tsum tau muab rhaub rau cov kua ua ntej siv. Kev kub siab dua ua rau muaj kev phom sij ntau dua rau kev siv. Emulsified asphalt yog derivative ntawm asphalt. Piv nrog asphalt, nws muaj qhov zoo ntawm kev tsim kho yooj yim, txhim kho kev tsim kho ib puag ncig, tsis xav tau cua sov, kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
Kev faib tawm ntawm emulsified asphalt:

1. Muab faib raws li kev siv
Emulsified asphalt yog cais raws li txoj kev siv, thiab nws txoj kev siv kuj tuaj yeem piav qhia los ntawm txoj kev siv. Cov tshuaj tsuag-hom emulsified asphalt feem ntau yog siv los ua cov txheej txheem dej tsis sib haum, cov txheej txheem sib txuas, txheej txheej permeable, cov roj sealing, emulsified asphalt penetrating pavement, thiab txheej txheej emulsified asphalt nto kho tshuab. Mixed emulsified asphalt yuav tsum tau tov nrog pob zeb. Tom qab sib tov, nws tuaj yeem kis tau tusyees kom txog thaum lub emulsified asphalt yog demulsified thiab cov dej thiab cua evaporate, thiab tom qab ntawd nws tuaj yeem siv rau kev khiav tsheb. Kev sib xyaw emulsified asphalt tuaj yeem siv los ua cov txheej txheem dej tsis muaj dej lossis ua txheej txheej hauv kev tsim kho engineering. Feem ntau yog siv rau hauv slurry sealing, sib xyaw emulsified asphalt nto kho tshuab, emulsified asphalt gravel mix pavement, emulsified asphalt qhob pavement, kho cov pavement potholes thiab lwm yam kab mob, txias rov ua dua qub asphalt pavement cov ntaub ntawv thiab lwm cov txheej txheem kev tsim kho.
2. Muab faib raws li qhov xwm txheej ntawm asphalt emulsifiers
Emulsified asphalt yog cais raws li qhov xwm txheej thiab tuaj yeem muab faib ua: cationic emulsified asphalt, anionic emulsified asphalt, thiab nonionic emulsified asphalt. Tam sim no, cationic emulsified asphalt yog dav siv.
Cationic emulsified asphalt muaj cov yam ntxwv ntawm adhesion zoo thiab yog dav siv nyob rau hauv lub tsev waterproofing thiab kev loj kev tsim kho. Cationic emulsified asphalt tau muab faib ua peb hom raws li qhov ceev demulsification: ceev nrooj hom, nruab nrab cracking hom, thiab qeeb cracking hom. Rau cov ntawv thov tshwj xeeb, thov xa mus rau kev qhia txog emulsified asphalt thiab asphalt emulsifiers hauv Cov Khoom Siv. Kev sib tsoo qeeb tuaj yeem muab faib ua ob hom raws li lub sijhawm molding ntawm qhov sib tov: qeeb thiab ceev ceev.
Anionic emulsified asphalt tau muab faib ua ob hom: nruab nrab cracking thiab qeeb tawg. Lub demulsification ceev ntawm qhov sib tov yog qeeb teeb tsa.
Non-ionic emulsified asphalt tsis muaj qhov pom tseeb demulsification lub sijhawm thiab feem ntau yog siv rau cov cement thiab aggregate mixing thiab paving semi-rigid ruaj khov puag cov kev kawm thiab rau semi-rigid permeable txheej roj txau.
