Raws li cov txheej txheem ntau lawm, lub emulsified hloov nroj tsuag tuaj yeem faib ua peb hom: kev txuas ntxiv emulsified nroj ua haujlwm. Thaum lub sij hawm tsim cov emulsified hloov khoom, acid, thiab looj, thiab looj, thiab looj cov xab npum sib xyaw nrog butteroid nrog bitumen. Tom qab lub tank ntawm xab npum siv, nws tau rov ua dua nrog xab npum, thiab tom qab ntawd cov khoom tsim tawm ntawm lub tank txuas ntxiv.

Bitumen tso tsheb hlau luam yog "sab hauv cua sov hom cua hauv zos ceev bitumen cia khoom siv hluav taws xob ceev yog ". Cov koob tshiab tam sim no yog cov khoom siv as-tshaj plaws hauv Suav teb uas sib txuas lus kub ceev, lub zog txuag thiab kev tiv thaiv ib puag ncig. Cov khoom siv cua sov cov khoom siv cua sov hauv cov khoom tsis tsuas yog muaj roj cua sov ceev, tab sis kuj tsis yog qhov chaw ua haujlwm ib puag ncig, thiab yog ib qho yooj yim rau kev khiav lag luam, thiab yog qhov yooj yim ua haujlwm.

Dej yog ib qho ntawm cov ntaub ntawv raw ntawm cov hloov kho bitumen cia tank, thiab tau faib tawm hauv ntau cov khoom siv ntawm cov khoom siv tank tank tank. Raws li cov khoom siv uas cov dej tau faib, cov tshuaj txias txias los tiv thaiv tus mob los ntawm ib qho. Lub Tanken rho tawm tank dej tank dej tank, cov dej hauv lub taub dej tso tawm los ntawm lub lim valve. Qee cov twj paj nruag ntawm hloov kho bitumen cia tank tsis muaj lub lim valve kom txuag tau tus nqi ntawm cov khoom siv. Lub tailing mab lub tank nres tuaj yeem tsuas yog pleev xim los ntawm loosening cov flange bolts hauv qab. Lub twj tso kua dej ntawm cov hloov kho bitumen cia ntawm no suav nrog lub taub dej kub thiab nqus dej tawm. Hom dej tso kua dej rau cov hloov kho bitumen cia tank feem ntau siv cov raj xa hluav taws xob centrifugal twj tso kua mis. Muaj qhov dej phiab nyob rau hauv qab ntawm cov raj xa hluav taws xob hauv qab. Qhov hloov kho bitumen cia lub tank tank them nyiaj rau kev kho mob ntawm cov dej phwj dej hauv qab ntawm lub twj tso kua mis.

Coob tus phooj ywg hauv txoj kev tsim kev lag luam yuav ntsib tib qhov teeb meem thaum yuav xaiv ib qho kev tsim kho ntawm kev teeb tsa li cas ntawm asphalt tus nqi? Ua ntej daws cov teeb meem, cia kuv piav qhia rau koj cov kev teeb tsa kev teeb tsa ntau yam ntawm Bitumen cov neeg tuaj qhia tam sim no. Nyob rau tam sim no, muaj peb hom yooj yim ntawm asphalt kis cov kev teeb tsa. Feem ntau asphalt kis cov tuam ntxhab koom nrog lawv ua peb hom. Tag nrho lwm cov kev teeb tsa tau hloov los ntawm peb hom no. Asphalt cov khaub thuas yog zoo li peb xim ntawm xwm. Lwm cov xim yog txhua qhov ua los ntawm peb xim. Tau hais tias, Kuv ntseeg tias koj yog heev xav txog dab tsi peb yooj yim aslyrhalt kis cov khoom lag luam tsheb yog? Cia kuv piav qhia lawv ib leeg ib nrab.

Thaum kev yuav cov kws ntsuam xyuas kev sib xyaw ua ke, cov chaw tsim khoom siv ua haujlwm ua kom nco txog lubrication lubrication ntawm cov khoom siv, suav nrog lubrication ntawm txhua. Hauv qhov no, cov neeg siv kuj tau tsim cov qauv nruj nruj los tswj nws, raws li hauv qab no:

Asphalt sib xyaw ua ke muaj cov txiaj ntsig zoo thiab cov yam ntxwv, uas tau qhia hauv qab no.
