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

1. Kev cais los ntawm kev siv cov qauv
Emulsified asphalt yog cais raws li txoj kev siv, thiab nws siv kuj tuaj yeem piav qhia los ntawm txoj kev siv. Tshuaj tsuag-hom emulsified feem ntau yog siv los ua cov roj dej txheej, txheej txheej asphalt nkag, thiab txheej txheej-tso tawm emulsified urhalt nto. Sib tov emulsified ayhalt xav tau sib xyaw nrog pob zeb. Tom qab sib tov, nws tuaj yeem kis tau tusyees txog thaum lub emulsified asphalt yog demulsified thiab cua thiab cua ua tau siv rau kev tsheb ib txwm muaj. Sib tov emulsified evhalhalt tau siv ua txheej dej dej los yog ua ib txheej txheej saum npoo av hauv kev txij nkawm kev tsim kho. Mas siv nyob rau hauv slurry sealing, sib xyaw emulsified asrical kev sib tsoo, emulsified asphalt qhob cov ntaub ntawv, emulsified asporhalt ua ke ntawm cov ntaub ntawv asphalt uas txias thiab lwm yam kev sib xyaw ua ke.
2. Qhia tshwj xeeb raws li cov particle qhov ntawm asphalt emulsifiers
Emulsified asphalt yog cais raws li patalle qhov thiab tuaj yeem faib ua: cationic emulthified asshalt, thiab noculified asphalt. Tam sim no, cationic emulsifuav yog siv dav.
Cationic emulsified asphalt muaj cov yam ntxwv ntawm cov khoom zoo adhesion zoo thiab yog siv dav hauv kev tsim cov hluav taws xob waterproofing thiab kev tsim kho siab. Cationic emulsified asphalt tau faib ua peb hom raws li kev nrawm nrawm: hom tawg ceev, thiab hom tawg qeeb. Txog cov ntawv thov tshwj xeeb, thov saib cov lus qhia ntawm emulsified asphalt thiab asphalt emulsifiers hauv cov ntaub ntawv kho. Qeeb qeeb tawg tuaj yeem faib ua ob hom raws li lub sijhawm moulding ntawm qhov sib tov: Kev teeb tsa qeeb thiab chaw ceev.
Anionic emulsified ashhalt tau faib ua ob hom: nruab nrab tawg thiab qeeb tawg. Lub demulsification ceev ntawm qhov sib tov yog qhov chaw qeeb.
Tsis yog-ionic emulsified asshalt lub sijhawm thiab yog siv rau cov kev kawm sib xyaw thiab kev sib sau ua ke txheej txheej roj teeb txau.
Yuav ua li cas xaiv uas emulsified ashalhalt siv hauv daim ntawv thov? Koj tuaj yeem xa mus rau cov ntawv no, lossis sab laj rau lub vev xaib cov kev pab cuam! Ua tsaug rau koj cov kev saib xyuas thiab txhawb!
