Tom qab cov neeg asphalt no tau siv rau ib lub sijhawm, ntau yam tsuas yog tsim tawm ntawm cov khoom siv. Yog tias nws tsis huv tau ntev, txheej txheej tuab yuav tsim, uas yog qhov nyuaj rau kom huv. Txawm hais tias qhov kev ntxuav tu txhua tus paub, peb yuav tsum tau them sai sai rau qee cov teeb meem asphalt kis teeb meem thaum tu.
Raws li peb txhua tus paub, asphalt tus repters yog tsuas yog siv rau kev tsim kho, thiab lawv yuav ua rau ntau stains thaum siv. Nyob rau lub sijhawm no, peb tuaj yeem siv cov cav diesel rau kev ntxuav. Rau stains ntawm ib qho phab ntsa tuab, peb tuaj yeem ua ntej ntxuav lawv los ntawm kev siv lub cev, thiab tom qab ntawd ntxiv cov cav diesel kom tu. Thaum lub qhov cub yog roj-nqus thiab polished, lub tso sab kaw yog nqa tawm kom ntseeg tau tias muaj kev phom sij hauv chaw ua haujlwm. Nws yog ib qho yooj yim rau kev ua pa lom tau thaum twg los tau tshem tawm cov pov tseg rau hauv qab ntawm asphalt kis. Nws yog ib qho tsim nyog los ua txoj haujlwm zoo ntawm asphalt kis tiv thaiv kom tsis txhob muaj kev lom.

Ib qho ntxiv, nws yog qhov tsim nyog los tshawb xyuas cov xwm txheej technical ntawm cov cua thiab cov khoom cua txias thiab nqa tawm cov khoom cua centrifugal Lub cavern asphalt kis thiab hauv qab daus yuav tsum tau ua pa txuas ntxiv, thiab lub qhov ncauj sab sauv ntawm cov kab ke uas asphalt kis yuav tsum tau muab ntim rau thaum lub qhov cua sib tsoo yuav cuam tshuam. Tshawb xyuas seb cov khaub ncaws hnav thiab nqus khaub ncaws tiv thaiv thiab nqus pa ntawm cov khaub ncaws dab ntawm Asphalt ua tau raws li cov kev ua ntej ntawm asphalt kis; Txheeb xyuas cov ntaub ntawv thiab khoom siv (ntoo) ua tau raws li cov ntaub ntawv tawg, nkag mus tshem tawm cov pov tseg tom qab sib tham cov qauv.
Raws li cov khoom siv asphalt uas asphalt, cov khoom siv asphalt muaj cov yam ntxwv zoo. Nws muaj peev xwm ntau lawm thiab cov khoom yuav tsum tau ua kom nws tau cuam tshuam txog kev siv tshuab ntawm kev ua kom asphalt kis. Puas yog kev siv cov tshuaj ntsuab asphalt ntawm ib puag ncig phooj ywg thiab lub zog-txuag?
Qee cov tuam ntxhab tau ntxiv ib qho kev tiv thaiv ib puag ncig ib puag ncig rau cov khoom siv lawv tsim khoom, cov khoom siv kub ua qias tuaj. Rov ua dua tshiab ntawm lub tshav kub rov qab los ntawm kev siv hluav taws xob. Nyob rau hauv cov txheej txheem ntau lawm, raws li cov khoom tiav, cov inlet thiab qhov hluav taws xob ntawm inelet thiab qhov hluav taws xob ntawm aspulhalle qhob 95 ° C. Lub vaporization kub nyob rau hauv emulsified asphalt yog tsis siv los ntawm ntau asphalt cov tshuaj ntsuab, tab sis ncaj qha nkag mus rau cov khoom tiav tank, thiab cov cua sov ploj, ua rau muaj kev ploj kev ploj.
Hauv cov txheej txheem ntau lawm ntawm cov khoom siv asphalt, dej, raws li kev tsim cov khoom nyoos, yuav tsum tau ua kom sov los ntawm chav sov txog li 55 ° C. Qhov kub ntawm vaporization ntawm emulsified asphalt yog pauv mus rau lub kua. Nws pom tau tias tom qab 5 tons ntawm emulsified asphalt yog tsim tawm, qhov ntsuas kub, qhov kub ntawm txias ncig ua dej nce tob tob tob. Cov dej ntau lawm siv cov dej txias ncig ua si, thiab cov dej tsis tas yuav tsum ua kom sov. Nws tuaj yeem txuag tau 1 / 2 ntawm cov roj tsuas yog los ntawm lub zog. Yog li ntawd, kev siv ntawm asphalt kis tau tuaj yeem ua tiav lub zog txuag thiab ib puag ncig kev tiv thaiv raws li cov kev cai.
