Emulsified asphalt khoom yog cov cuab yeej tshwj xeeb siv los tsim emulsified asphalt. Nws cov yam ntxwv yog tias nyob rau hauv qhov kev txiav txim ntawm emulsifier, asphalt yog tawg mus rau hauv me me hais los ntawm mechanical quab yuam thiab tusyees dispersed nyob rau hauv dej los tsim ib tug ruaj khov emulsion, uas yog emulsified asphalt. Emulsified asphalt feem ntau yog siv los ua cov txheej txheem permeable, cov txheej txheem sib txuas thiab cov ntaub ntawv ntog hauv txoj kev loj thiab hauv nroog txoj kev. Nws kuj tseem tsim nyog rau kev npaj cov txheej txheem dej tsis zoo thiab cov dej tsis zoo hauv kev tsim kho kev lag luam.
Tom qab ntau xyoo ntawm txoj kev loj hlob, cov kev qhia tshwj xeeb thiab ntau yam ntawm emulsified asphalt cov cuab yeej tau nce ntxiv, cov qauv kev ua tau zoo tau nce zuj zus, thiab cov txheej txheem tau mus txog qib siab heev. Tshwj xeeb, ua tiav cov khoom siv emulsified asphalt tau tsim nyob rau xyoo tas los no tau txais ntau yam kev siv thev naus laus zis niaj hnub los ua kom tau raws li qhov xav tau ntawm kev tsim ntau yam asphalt emulsions. Nws cov yam ntxwv technical tuaj yeem muab sau ua ob lub ntsiab lus hauv qab no:
(1) High degree ntawm automation, metering asphalt, dej emulsion thiab ntau yam additives tuaj yeem tswj tau, thiab txiav nyiaj them rov qab, kaw thiab kho.
(2) Kev sib xyaw ua ke ntawm cov khoom tseem ceeb yog yooj yim rau disassemble thiab txav mus. Piv txwv li, lub tuam txhab American Scandinavia Road txuas thiab txhim kho cov khoom tseem ceeb xws li colloid zeb, tswj txee, twj tso kua mis, ntsuas ntsuas hauv lub thawv txheem. Thaum ua haujlwm, nws tsuas yog yuav tsum tau txuas cov kav dej thiab lub zog hluav taws xob.
kuv lub teb chaws pib siv cov txheej txheem emulsification thaum ntxov 1980s, thiab cov emulsifier feem ntau yog colloid zeb. Lub ntsiab feature ntawm cov cuab yeej no yog hais tias lub dissolution thiab dilution ntawm lub emulsifier yog nqa tawm nyob rau hauv batch, thiab ces muab cia rau hauv lub emulsifier dej tov tank rau standby siv. Txij li thaum xyoo 1990, cov cuab yeej siv emulsified asphalt ntau dua hauv Suav teb tau nruab nrog lub computer tsis siv neeg tswj cov cuab yeej, uas zoo heev txhim kho kev tswj qhov tseeb ntawm cov roj-dej piv ntawm asphalt emulsion.
Nrog rau kev nce qib thiab kev siv emulsified asphalt slurry sealing tshuab hauv kuv lub teb chaws, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau qhov zoo thiab cov khoom siv emulsified asphalt, thiab emulsified asphalt khoom tau tsim nyob rau hauv cov kev taw qhia ntawm standardization thiab rationalization.
