Emulsion bitumen yog qhov emulsion tshiab tsim los ntawm kev txiav txim siab ua ntej asphalt thiab emulsifier aqueous daws.
Emulsion Bitumen tau faib raws li cov khoom sib txawv ntawm bitumen emulsifier bitumen thiab noionic emulsion bitumen.
Ntau tshaj 95% ntawm txoj kev kev tsim kho siv Cationic emulsion bitumen. Vim li cas cov cationic emulsion bitumen muaj qhov zoo?

1. Cov dej xaiv tau yog qhov dav. Bitumen, dej thiab bitumen emulsifier yog cov ntaub ntawv tseem ceeb rau emulsion bitumen. Anionic emulsified bitumen yuav tsum tau npaj nrog dej mos thiab tsis tuaj yeem raug diluted nrog dej nyuaj. Rau cationic emulsion bitumen, koj tuaj yeem xaiv emulsion bitumen rau dej nyuaj. Koj tuaj yeem siv cov dej nyuaj los npaj ib qho emulsifier aqueous, lossis koj tuaj yeem devute ncaj qha nws.
2. Yooj yim ntau lawm thiab zoo ruaj khov. Qhov kev ruaj ntseg ntawm AST yog neeg pluag thiab admixtures yuav tsum tau ntxiv kom muaj kev ruaj ntseg ntawm cov khoom tiav ntawm cov khoom tiav. Feem ntau, cationic emulsion bitumen tuaj yeem tsim emulsion ruaj khov me ntsis yam tsis ntxiv lwm yam ntxiv.
3. Rau cationic emulsion bitumen, muaj ntau txoj hauv kev los kho cov demulsification ceev thiab tus nqi tsawg.
4. Cationic Emultified Asphalt tseem tuaj yeem tsim ua ib txwm muaj hauv cov caij nyoog noo lossis qis qis (saum 5 ℃).
5. Zoo adhesion rau pob zeb. Cationic emulsion bitumen hais cov nqi cationic. Thaum nyob hauv kev sib cuag nrog pob zeb, cov asphalt hais tau tawm tswv yim nrawm nrawm rau saum npoo ntawm pob zeb vim qhov nyiam ntawm cov khoom sib txawv. Siv nyob rau hauv micro surfacing thiab slurry foob siv.
6. Lub viscosity ntawm cationic emulsion bitumen yog qhov zoo dua li ntawm anionic emulsion bitumen. Thaum pleev xim, cationic emulsion bitumen yog qhov nyuaj dua, yog li koj tuaj yeem xaiv tshuaj tsuag nws. Ntawm qhov tsis sib xws, anionic emulsion bitumen yog yooj yim los pleev xim. Nws tuaj yeem siv tau ua penetating txheej txheej roj thiab lo txheej roj hauv kev tsim cov dej thiab txoj kev paving.
7. Cationic emulsion bitumen qhib kev tsheb khiav nrawm.
