Asphalt melter cov cuab yeej yuav tsum tau ua qee yam kev sim. Dab tsi yog cov ntsiab lus tseem ceeb ntawm nws txoj kev xeem? Kuv tsis paub ntau npaum li cas peb yeej paub. Peb yuav tsum nkag siab cov ntaub ntawv yooj yim ua ntej siv nws. Tam sim no peb yuav muab koj cov lus piav qhia ntxaws:
Cov asphalt specimen yog rhuab thiab lim, thiab ib qho kev faib ua feem ntawm cov tshuaj tiv thaiv flake yog ntxiv, thiab sib tov los ntawm tes los yog nrog ib tug stirring ntaus ntawv kom cov anti-flaking tus neeg saib xyuas tusyees dispersed nyob rau hauv asphalt specimen; Cov yas zaj duab xis cua sov yog ua los ntawm cov qauv rau cov cua sov Rau cov laus, siv cov kauj ruam dej los yog dej boiling txoj kev kuaj cov adhesion ntawm asphalt thiab crude asphalt sib tov;
Thaum tsim nyog, peb tuaj yeem siv cov khoom sib xyaw asphalt uas tsis tau ua kom sov thiab muaj hnub nyoog nrog cov yeeb yaj kiab yas los ua qhov kev ntsuam xyuas adhesion, lossis peb tuaj yeem siv cov cement pob zeb uas tsis tau muaj hnub nyoog los ua cov kev ntsuam xyuas kab rov tav thiab ua cov kev sib piv los txiav txim siab qhov kub ntawm cov khoom siv. anti-stripping tus neeg sawv cev. tshaj qhov kev siv mus sij hawm ntev.
Ua raws li kev kho mob nrawm nrawm rau kev sib xyaw kub asphalt sib tov siv cov tshuaj tiv thaiv stripping; ua dej immersion Marshall kev ntsuam xyuas thiab impulsive crusher kev ntsuam xyuas ntawm cov mixs los soj ntsuam cov kab rov tav stability ntawm asphalt mixs.
Txoj kev sim tseem ceeb ntawm cov khoom siv asphalt melter yog qhov no. Peb yuav tsum ua cov haujlwm ua haujlwm tau zoo raws li cov lus qhia, txhawm rau ua kom pom tseeb nws cov yam ntxwv. Ib tug loj tus naj npawb ntawm high-tech technologies muaj feem xyuam rau asphalt melter cov cuab yeej yuav raug txheeb tawm rau koj dua. Zoo siab txais tos saib tam sim no.
