Txhim kho cov khoom siv ntau lawm ntawmHloov Kho Cov Nroj Tsuagyog txoj kev tsom xam ntawm ntau lub tuam txhab. Nov yog qee cov hau kev thiab cov lus qhia los pab ua kom ua kom zoo ua haujlwm thiab nce ntau lawm.
Ua ntej, kom ntseeg tau tias cov khoom siv tau zoo khaws cia yog lub hauv paus rau kev txhim kho kev ua tau zoo. Kev tshuaj xyuas ib txwm ntawm cov agitators xws li cov cua sov, cua sov, thiab cov raj xa khoom tuaj yeem txo qhov tshwm sim ntawm kev ua tsis tiav. Piv txwv li, yog tias tus agitator blades hnav lossis cov cua sov kev ua haujlwm txo qis, nws yuav ua rau muaj kev sib xyaw tsis sib xyaw lossis siv hluav taws xob tsis sib xyaw. Yog li, kom raws sij hawm hloov chaw thiab tu cov thaiv cov chaw tuaj yeem ua rau cov khoom lag luam du ntawm cov khoom siv.
Thib ob, nws tseem yog ib qho tseem ceeb kom ua kom tiav cov txheej txheem ntau lawm. Los ntawm kev kho qhov kub, nplawm kev sib piv, thiab cov ntaub ntawv piv, hloov kho cov txiaj ntsig ntawm asphalt tuaj yeem txhim kho thiab nrawm dua. Piv txwv li, kev nce qib kev tsim nyog yuav ua kom nrawm dua cov tshuaj tiv thaiv kev siv tshuaj, tab sis overheating yuav tsum zam kom ua rau cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, siv cov tshuab tswj kev siv hluav taws xob txhawm rau saib xyuas thiab kho cov tsis tuaj yeem txo cov neeg yuam kev thiab muaj kev ruaj ntseg.
Thib peb, kev xaiv ntawm cov ntaub ntawv raw zoo muaj qhov cuam tshuam ncaj qha rau kev tsim tau kev ua haujlwm. Cov khoom siv tsis zoo cov khoom siv hluav taws xob yuav muaj cov impurities, nce kev lim thiab ua lub sijhawm siv, thiab yog li txo qhov ua tau zoo tag nrho. Xaiv cov ntaub ntawv raw uas ua tau raws cov qauv uas tsis tuaj yeem txo cov kauj ruam nkaus xwb, tab sis kuj txhim kho qhov zoo ntawm cov khoom kawg. Tsis tas li ntawd, kev yuav cov khoom siv raw hauv cov khoom ua ntej tuaj yeem txo lub sijhawm tos sijhawm thiab tsheb thauj mus los.
Los ntawm cov kev ntsuas saum toj no, kev lag luam tuaj yeem txhim kho ntau cov khoom ua haujlwm ntawm kev hloov kho bitumen hloov kho. Cov hau kev no tsis tsuas yog pab txo cov nqi, tab sis tseem txhim kho cov khoom lag luam zoo, tso lub hauv paus rau kev txhim kho ntev ntawm kev lag luam.
