Cov khoom hloov kho bitumen tuaj yeem muab faib ua ntau hom. Cov cuab yeej hloov kho bitumen tuaj yeem muab faib ua peb hom: kev ua haujlwm tsis sib xws, hom kev ua haujlwm ib ntus, thiab kev ua haujlwm tsis tu ncua raws li cov txheej txheem kev ua haujlwm. Rau ntau hom kev hloov kho bitumen Dab tsi yog qhov kev nkag siab zoo ntawm cov cuab yeej?

Hloov cov ntaub ntawv emulsify bitumen. Thaum lub sij hawm tsim khoom, demulsifier, acid, dej, thiab latex hloov cov ntaub ntawv yog tov nyob rau hauv ib tug xab npum tov tank, thiab ces cov emulsified bitumen underwater pob zeb yog muab tso rau hauv ib tug colloidal tov zeb. Kev siv cov bitumen cia tso tsheb hlau luam yuav tsum xav txog kev tsim cov khoom siv txuas ntxiv ntawm bitumen sib tov sib xyaw tshuab, thiab zam kev nqis peev ntau, uas yuav ua rau kev noj thiab nce nqi. Tus nqi yuav tsum tau txiav txim kom zoo raws li kev noj bitumen.

Tom qab siv ib lub kaus poom, cov xab npum tau npaj, thiab tom qab ntawd pib cov khoom siv tom ntej. Thaum siv los tsim cov hloov kho emulsified bitumen, nyob ntawm seb lub tshuab ntawm cov khoom hloov kho, cov kav dej latex tuaj yeem txuas ua ntej lossis tom qab micronizer. Tej zaum yuav tsis muaj lub raj xa dej tshwj xeeb, tab sis phau ntawv qhia. Ntxiv tus nqi ntawm cov latex rau hauv lub thawv xab npum.

Cov cuab yeej hloov kho bitumen tiag tiag yog ib qho kev hloov kho bitumen cov cuab yeej nruab nrog cov xab npum ua kua sib tov, thiab cov kua xab npum tuaj yeem hloov tom qab los xyuas kom meej tias cov xab npum ua kua tsis tu ncua rau hauv cov tshuaj tov tshuaj. Bitumen cia tank yog lwm yam tshiab ntawm bitumen cua sov cia khoom tsim los ntawm kev sib txuas cov yam ntxwv ntawm cov tsoos high-temperature thermal roj-rhuab bitumen cia tso tsheb hlau luam thiab sab hauv hluav taws kub bitumen cua sov tso tsheb hlau luam.

Cov yam ntxwv ntawm cov khoom siv hloov kho bitumen yog: cua kub ceev, kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob, cov khoom siv loj, tsis muaj kev siv dab tsi, tsis muaj kev laus, thiab kev ua haujlwm yooj yim. Txhua qhov chaw tuaj yeem ntsia tau rau ntawm lub tank, txav mus, hoisted, thiab tshuaj xyuas, uas yooj yim tshwj xeeb. Nws yog qhov yooj yim heev rau kev txav mus los. Cov khoom no tuaj yeem ua kom sov cov bitumen kub txog 160 degrees hauv tsawg dua 30 feeb.
