Muaj ob hom kev hloov kho tseem ceeb rau cov khoom siv emulsified asphalt: sab nraud sib xyaw thiab txoj kev sib xyaw sab hauv. Txoj kev sib xyaw sab nraud yog ua ntej ua cov khoom siv emulsified asphalt, tom qab ntawd ntxiv cov polymer latex modifier rau cov khoom siv emulsified asphalt, thiab sib tov thiab ua kom nws. Cov polymer emulsion feem ntau tshwm sim li CR emulsion, SBR emulsion-hais txog acrylic emulsion, thiab lwm yam. Cov kev sib xyaw sab hauv yog ua ntej sib tov roj hmab, yas thiab lwm yam polymers thiab lwm yam additives rau hauv cov xim kub asphalt. Tom qab sib tov sib npaug thiab nrhiav pom qhov tshwm sim ntawm cov polymer thiab cov xim asphalt, cov polymer hloov asphalt tau txais. Cov kauj ruam tom ntej yog hloov kho asphalt emulsion yog tsim los ntawm kev kos duab emulsification, thiab cov polymer feem ntau siv hauv kev sib xyaw ua ke yog SBS. Yog tias cov khoom siv xim asphalt raug tso tseg rau ib teev tom qab sib tov, ntxuav qhov chaw ntawm qhov sib tov, ntxiv dej huv, thiab txhuam cov mortar kom huv si. Tom ntej no, ntws dej, xyuas kom meej tias tsis muaj cov dej ntim hauv lub thoob kom tsis txhob muaj kev hloov pauv hauv daim ntawv qhia lossis txawm tias xeb hauv cov txheej txheem ua haujlwm xws li lub vev xaib. Thaum lub sij hawm tus txheej txheem, txhua leej txhua tus paub yuav tsum tau them tshwj xeeb mloog mus rau ntau yam me me cov txheej txheem kom tsis txhob poob tsis tsim nyog rau lawv tus kheej kev khiav hauj lwm.

Kev khiav hauj lwm txheej txheem ntawm emulsified asphalt khoom:
Kev puas tsuaj saum npoo ntawm emulsified asphalt cov cuab yeej thiab dej yog qhov sib txawv heev, thiab lawv tsis yooj yim sib xyaw nrog ib leeg ntawm qhov kub thiab txias. Thaum cov khoom siv emulsified asphalt tau txais kev ua haujlwm xws li centrifugation, txiav, thiab cuam tshuam, cov khoom siv emulsified asphalt hloov mus rau hauv cov khoom uas muaj qhov loj me ntawm 0.1 ~ 5 μm, thiab muab faib rau hauv cov dej uas muaj surfactant (emulsifier-stabilizer) hauv nruab nrab. , lub emulsifier tuaj yeem raug coj los ua adsorbed rau ntawm qhov chaw ntawm cov khoom siv xim asphalt emulsified, yog li txo qhov kev sib tshuam ntawm cov dej thiab cov xim asphalt, tso cai rau cov xim asphalt los ua ib qho kev zoo siab hauv dej. Cov khoom siv emulsified asphalt thiab cov khoom siv yog roj-hauv-dej. ntawm emulsion. Hom kev faib tawm no yog xim av, nrog cov xim asphalt raws li cov txheej txheem tawg thiab dej raws li theem txuas ntxiv, thiab nyiam cov dej ntws zoo heev ntawm chav tsev kub. Emulsified asphalt cov cuab yeej thiab cov chaw hauv kev nkag siab, emulsified asphalt cov cuab yeej thiab cov chaw siv dej "khoov" cov xim asphalt, yog li tswj cov fluidity ntawm cov xim asphalt.
Emulsified asphalt khoom kub-melts yooj yim xim asphalt thiab mechanically faib me me xim asphalt hais nyob rau hauv ib tug aqueous tov uas muaj emulsifier los ua ib tug kua xim asphalt khoom. Cov cement emulsified asphalt khoom mortar siv nyob rau hauv slab ballastless khiav siv cationic emulsified asphalt khoom. Lub hom phiaj yog los kho cov elasticity, toughness thiab durability ntawm cov cement emulsified asphalt khoom mortar. Polymers feem ntau yog siv los hloov cov asphalt.
