Qhov cuam tshuam ntawm kev tswj qhov kub thiab txias ntawm cov cuab yeej hloov kho bitumen
Hauv kev npaj cov khoom siv hloov kho bitumen, kev tswj qhov kub thiab txias yog qhov tseem ceeb heev. Yog tias qhov kub ntawm bitumen tsawg dhau, cov bitumen yuav thicker, kua dej tsawg, thiab nyuaj rau emulsify; Yog hais tias qhov kub ntawm bitumen siab dhau lawm, ntawm ib sab, nws yuav ua rau lub hnub nyoog ntawm bitumen. Nyob rau tib lub sijhawm, qhov kub ntawm qhov nkag thiab qhov hluav taws xob ntawm emulsified bitumen yuav siab dhau, uas yuav cuam tshuam rau kev ruaj ntseg ntawm emulsifier thiab qhov zoo ntawm emulsified bitumen. Dab tsi txhua leej txhua tus yuav tsum to taub yog tias bitumen yog ib qho tseem ceeb ntawm emulsified bitumen, feem ntau suav rau 50% -65% ntawm tag nrho cov zoo ntawm emulsified bitumen.
Thaum cov emulsified bitumen yog txau los yog tov, cov emulsified bitumen yog demulsified, thiab tom qab cov dej nyob rau hauv nws evaporates, dab tsi yog tshuav nyob rau hauv av yog bitumen. Yog li ntawd, kev npaj ntawm bitumen yog ib qho tseem ceeb tshwj xeeb. Tsis tas li ntawd, txhua tus neeg yuav tsum nco ntsoov tias thaum emulsified bitumen cog yog tsim, viscosity ntawm bitumen txo qis thaum qhov kub nce. Rau txhua txhua 12 ° C nce, nws dynamic viscosity kwv yees li ob npaug.
Thaum lub sij hawm ntau lawm, lub hauv paus cultivation bitumen yuav tsum xub muab rhuab rau cov kua ua ntej emulsification yuav nqa tawm. Txhawm rau hloov mus rau lub peev xwm emulsification ntawm micronizer, dynamic viscosity ntawm cultivation base bitumen feem ntau tswj tau li ntawm 200 cst. Qhov ntsuas kub qis dua, qhov viscosity siab dua, yog li lub twj tso kua mis bitumen yuav tsum tau hloov kho dua tshiab. thiab lub siab ntawm micronizer, nws tsis tuaj yeem emulsified; Tab sis ntawm qhov tod tes, txhawm rau kom tsis txhob muaj evaporation thiab evaporation ntawm cov dej ntau dhau ntawm cov khoom tiav thaum lub sij hawm tsim cov emulsified bitumen, uas yuav ua rau demulsification, thiab nws kuj yog ib qho nyuaj rau cua sov lub substrate bitumen siab dhau heev lawm. micronizer feem ntau yog siv. Qhov kub ntawm cov khoom tiav ntawm qhov nkag thiab tawm yuav tsum qis dua 85 ° C.
