Cov khoom siv twg yuav tsum to taub cov kev ua haujlwm zoo ua ntej thiab tom qab siv, yog li nws tsis tuaj yeem ua kom muaj kev nyab xeeb ntawm kev ua haujlwm. Peb txhua tus paub tias cov khoom siv emulsified ua haujlwm tseem ceeb hauv kev tsim kev tsim kho, thiab qhov ua tau zoo ntawm nws cov kev tsim khoom yuav cuam tshuam ncaj qha rau cov chaw zoo xws li txoj kev. Txhawm rau kom nws ua haujlwm zoo dua, peb yuav tsum tau them nyiaj tshwj xeeb rau plaub yam tseem ceeb thaum siv nws.

Thaum peb siv cov khoom siv emulsified bitumen, peb yuav tsum tau them nyiaj tshwjxeeb rau plaub yam no: 1. Cov khoom kub kub ntxiv rau cov khoom siv emulsified bitumen yuav tsum tau mus txog kev ua haujlwm kub ntawm 160 ~ 180 ℃. Txog kev thauj mus los ntev ntev los yog lub sijhawm ua haujlwm ntev, cov khoom siv cua sov tuaj yeem siv rau rwb thaiv tsev rwb thaiv tsev, tab sis nws tsis tuaj yeem siv ua hluav taws xob melting. 2. Thaum cua sov cov khoom siv abhalt hauv cov khoom siv emulsified nrog lub hlawv, cov bitumen qhov siab yuav tsum tau tshaj lub dav hlau sab saud ntawm cov kev sib txuas yuav raug hlawv. 3. Cov khoom siv tsis tuaj yeem sau tau tas mus li, thiab lub cap tsis zoo yuav tsum tau kaw kom nruj kom tiv thaiv tau me ntsis los ntawm kev thauj mus los. 4. Lub tsheb no muaj ob txoj kev tswj hwm, pem hauv ntej thiab nram qab. Thaum siv lub hauv ntej tswj console, koj yuav tsum tig hloov mus rau sab xub ntiag. Nyob rau lub sijhawm no, cov tswj sab tom qab tsuas yog tswj hwm qhov nce thiab poob ntawm lub nozzle.
