Thaum cov asphalt sib tov ua ke cov khoom siv cog yog hauv kev ua haujlwm, ntau plua plav, yog li ntawd nws yog ib qho tsim nyog kom muab nws nrog cov khoom tawg tshem tawm. Feem ntau, ib lub hnab av ntim hnab ntim tau siv, thiab cov hmoov av lim dej ua tau zoo, thiab qee cov kua qaub, alkali thiab kub tsis kam.

Dab tsi yog qhov zoo ntawm kev siv thev naus laus zis ntawm cov khoom siv emulsified bitumen? Raws li cov khoom emulsion bitumen, emulsified bitumen cog yuav tsum muaj kev txawj siab heev. Seb nws yog txoj kev ua tiav ntawm cov khoom siv emulsified bitumen lossis cov txheej txheem tsim khoom, yog tias koj tsis nkag siab qhov twg, cov cuab yeej ua tsis tau zoo lossis siv tsis tau.

Nrog kev txhim kho kev kawm txuas ntxiv ntawm science thiab thev naus laus zis, bitumen meterter khoom kuj tseem niaj hnub ua haujlwm thiab txhim kho. Yav tom ntej bitumen melting nroj tsuag yuav ntse dua, ib puag ncig phooj ywg. Los ntawm kev qhia thev naus laus zis xws li Internet ntawm cov khoom thiab cov cuab yeej siv kev ua haujlwm thiab cov ntaub ntawv tawm tsam thiab cov ntaub ntawv kev ua txhaum thiab cov ntaub ntawv kev ua txhaum thiab muaj peev xwm hloov kho.

Piv nrog cov tsoos kub thiab kev nce qib kub rov qab, cov qauv siv cov khoom kub qub lossis cov khoom rov qab kub dua yog cov khoom siv raw txias txias.

Hais txog kev tsim khoom, kev tswj hwm yog thawj kauj ruam los xyuas cov cuab yeej siv ntau yam xws li kev tswj hwm kev nyab xeeb ntawm kev ua haujlwm thiab txhua yam yog qhov tseem ceeb heev. Yog tias cov khoom siv tsis tuaj yeem ua haujlwm, kev tsim khoom tsis tuaj yeem txuas ntxiv, uas cuam tshuam rau kev nce qib ntawm tag nrho cov haujlwm. Yog li ntawd, kev tswj hwm ntawm asphalt sib tov ua ke cog khoom yog qhov kev xav tau lubrication ua haujlwm, uas muaj cov phiaj xwm kev txij nkawm, thiab kev tswj hwm ntawm cov khoom siv ntsig txog ntawm cov khoom siv.

Txhua yam khoom siv yuav tsum yog tsim, tsim thiab ntsia ua ntej lawv tuaj yeem ua haujlwm, thiab asphalt sib xyaw nroj tsuag tsis muaj kev zam. Yog li muaj qee qhov kev ceev faj hauv cov txheej txheem ntawm kev tsim qauv lossis teeb tsa. Koj puas paub lawv yog dab tsi? /

Ua ntej, cia peb qhia txog kev tsim qauv. Peb pom tias thaum tsim cov nroj tsuag liphalting li asphalt sib tov, ua haujlwm uas yuav tsum npaj ua ntej suav nrog kev tshawb fawb kev ua lag luam, cov ntaub ntawv thiab lwm qhov txuas. Tom qab ntawd, raws li cov kev xav tau tiag tiag, cov kev xav tau ua ke, thiab qee cov tswv yim tshiab yuav tsum tau txiav txim siab zoo thiab xaiv cov kev daws teeb meem tshaj plaws. Tom qab ntawd, cov qauv schematic ntawm cov tshuaj no yuav tsum tau kos.
