Muaj ob txoj hauv kev hloov pauv tseem ceeb rau cov khoom siv emulsified bitumen: kev sib xyaw sab nraud thiab txoj kev sib xyaw sab hauv. Txoj kev sib xyaw sab nraud yog ua ntej ua cov nroj tsuag zoo tib yam emulsified bitumen, tom qab ntawd ntxiv polymer latex modifiers rau cov khoom siv Shanxi emulsified bitumen zoo tib yam, thiab sib tov thiab do los npaj. Cov polymer emulsions feem ntau yog CR emulsions, SBR emulsions, thiab acrylic emulsions. Txoj kev sib xyaw sab hauv yog thawj zaug sib tov roj hmab, yas thiab lwm yam polymers thiab lwm yam additives rau hauv kub thiab txias-sib xyaw xim bitumen. Tom qab sib tov thiab sib npaug, thiab qhia cov txheeb ze cuam tshuam ntawm cov polymer thiab cov xim txias-mix bitumen, polymer-hloov bitumen tau txais. , thiab tom qab ntawd hloov kho bitumen emulsion yog kho los ntawm emulsification technology. Cov khoom siv polymer feem ntau siv hauv kev sib xyaw ua ke yog SBS. Yog tias cov khoom siv txias sib xyaw bitumen raug tso tseg rau ib teev tom qab nplawm, ntxuav qhov chaw ntawm lub thoob nplawm, ntxiv dej huv, thiab ntxuav lub mortar. Sau cov dej tom qab, thiab nco ntsoov tias tsis muaj cov dej ntim hauv lub thoob los tiv thaiv cov ntawv sau los ntawm kev hloov pauv, ua rau lub rooj sib tham thiab lwm txoj hauv kev zoo li rusty. Thaum siv nws raws li cov lus qhia, koj yuav tsum ua qee yam kev ntsuas yooj yim kom tsis txhob muaj qhov tsis tsim nyog rau kev ua haujlwm.

Kev khiav hauj lwm hauv paus ntsiab lus ntawm emulsion bitumen khoom:
Lub zog nro ntawm cov khoom siv emulsion bitumen thiab dej sib txawv heev, thiab lawv tsis sib haum nrog ib leeg ntawm qhov kub thiab txias. Thaum cov nroj tsuag emulsion bitumen raug rau cov khoom siv xws li ceev centrifugation, shearing, thiab cuam tshuam, cov khoom siv emulsion bitumen yuav hloov mus rau hauv cov khoom uas muaj qhov loj me ntawm 0.1 ~ 5 μm, thiab tawg mus rau qhov chaw uas tsis muaj surfactant ( emulsifier-stabilizer) Nyob rau hauv cov dej nruab nrab, vim hais tias cov emulsifier tuaj yeem adsorbed rau saum npoo ntawm Shanxi emulsified txias-sib xyaw xim bitumen hais ntawm cov ntsiab lus ruaj khov, qhov sib txuam ntawm cov dej thiab cov xim txias-sib xyaw xim bitumen txo, kom qhov txias- sib tov xim bitumen hais tuaj yeem tsim kom muaj kev ruaj ntseg tawg hauv dej. , emulsion bitumen cov cuab yeej teeb tsa yog cov roj-hauv-dej emulsion. Xws li cov txheej txheem tawg yog xim av xim av, nrog cov xim txias sib xyaw bitumen raws li cov theem tawg thiab dej raws li theem txuas ntxiv, thiab muaj qhov dej zoo ntawm chav tsev kub. Emulsion bitumen equipments installation Nyob rau hauv ib qho kev nkag siab, emulsion bitumen cov cuab yeej siv los "sib cais" txias-siv cov xim bitumen nrog dej, yog li kev sib koom ua ke ntawm fluidity ntawm txias-siv xim bitumen.

Cov emulsified bitumen cog kub-melts lub hauv paus txias-sib xyaw xim bitumen, thiab tom qab ntawd disperses cov me ntsis txias-mixed xim bitumen hais rau hauv cov kua dej uas muaj emulsifier los ntawm lub tshuab los ua kua txias-sib xyaw xim bitumen nplooj ntawv. Cov cement emulsified bitumen khoom mortar siv rau slab ballastless khiav qauv siv cationic emulsion bitumen cog. Txhawm rau tswj hwm qhov elasticity, toughness thiab zoo ntawm cov cement emulsified bitumen cov cuab yeej mortar, polymers feem ntau siv los hloov cov bitumen.
