Emulsified asphalt yog ib tug emulsion tsim los ntawm asphalt dispersed hauv dej. Cov dej nyob hauv nws tsuas yog nruab nrab ib ntus hauv asphalt. Tom qab emulsified asphalt yog txau los yog sib xyaw, nws tawg cov emulsion thiab dej hauv emulsified asphalt evaporates. Qhov piv txwv ntawm cov dej mus asphalt hauv emulsified asphalt tsis tsuas yog cuam tshuam rau kev tsim khoom asphalt, tab sis kuj tseem muaj qhov cim kev ruaj khov, viscosity thiab lwm yam qhia tau asphalt. Yog li ntawd, nws yog qhov tsim nyog los kuaj cov lus asphalt cov ntsiab lus hauv emulsified asphalt.
Txhawm rau txhawm rau txhawm rau cov asphalt cov ntsiab lus hauv emulsified asphalt, lub emulsified asphalt xav tau lub cev qhuav dej. Txawm li cas los xij, ntau lub teb chaws cov teb chaws thiab cov koom haum muaj cov txheej txheem sib txawv rau lub cev qhuav dej ntawm epulsify. Hauv cov ntsiab lus, muaj plaub txoj kev tseem ceeb: distillation, cub evaporation, kev ua cua ua cua duab degure evaporation thiab cua txias.

1. Distillation Txuj Ci
Txoj kev sawv cev tawm tsam distillation ntau yog cov txheej txheem distillation ntawm cov astm hauv Tebchaws Meskas, thiab lub sijhawm sib txawv nrog ntau lub xeev thiab cov tub sab Distillation siv nyob hauv Tebchaws Meskas.
(1) cov txheej txheem distillation. Tsoomfwv Meskas ASTM D244-00 teev peb txoj kev rau kev rho tawm emulsified asrhalt, thiab cov roj av los ntawm evaporation, thiab tsawg (135 ° c) nqus distillation. Lub astm distillation txoj kev yog rau ncuav 200g ntawm hloov emulsified emultified rau hauv 26 feeb los cais cov dej thiab asphalt nyob rau hauv emulsified asphalt. Cov seem tau txais los ntawm cov qauv no tseem siv tau los sim cov khoom ntawm seem ntawm aslobual.
(2) Astm tsawg-tshuab cua txias distillation. Xav txog tias qee cov khoom tawg paj hluav taws xob, tshwj xeeb tshaj plaws emulsified asphalts, cov khoom ntawm cov khoom lag luam asphalt, cov khoom ntawm cov khoom siv asphaltly, cov khoom ntawm cov kev cuam tshuam zoo heev ntawm lub xeev emulsified assochalt thaum siv. Yog li ntawd, qhov qis-kub siab distillation txoj kev tau ntxiv rau 2000 tsab ntawm Astm D244. Cov qauv no siv cov twj paj nruag thiab cov distills distillation ntawm 135 ° C rau 60 feeb.
(3) Cov hau kev distillation nrog lub sijhawm sib txawv thiab lub sijhawm nyob hauv ntau lub xeev hauv Tebchaws Meskas. Ntau lub xeev hauv Tebchaws Meskas siv distillation kom tau txais emulsified realidues, oklas thiab Penninois siv ib txoj kev ntawm distilling ntawm 204 ° C rau 15 feeb, thiab lwm yam.
2. Cub evaporation qauv
Cov neeg sawv cev ntau dua yog cov assm evaporation qauv thiab txoj kev ntawm California, USA.
Lub AHTM evaporation txoj kev yog coj plaub beakers nrog lub peev xwm ntawm ib qho cub rau cua sov rau cua sov rau 1h thiab coj lawv tawm mus ntsuas qhov ntsuas ntawm qhov chaw seem.
Cov txheej txheem hauv California, Tebchaws Asmeskas yog coj los ua 40G ± 0.1g ntawm emulsified ashrhalt, khaws nws ntawm 138 ℃, do nws, thiab khaws nws ntawm 138 ℃ rau 1h. Cov uas tau txais qhov seem yog ua rau hauv cov hnoos qeev kom ntsuas qhov ntsuas ntsuas ntsuas.
3. Kev Ua Si Cua Sov Cov Qauv evaporation
Ob txhais lus Nyij Pooj thiab kuv lub tebchaws siv cov qauv no. Qhov kev xeem rau kev ua kom muaj kev cuam tshuam evaporation hauv kuv lub teb chaws yog kom ua kom sov, thiab tom qab ntawd cov dej muaj thaum muaj 1 xyoos tom qab sau cov pwm. Txoj kev ntsuas no yog tsim nrog siv rau Japanese cov qauv.
Tsis tas li ntawd, txhawm rau muab cov piv ntawm asphalt rau dej hauv emulsified asphalt, tab sis kuj yog los ntawm kev pom cov ntsiab lus dej hauv emulsified. ASTM D244-00 tseem muaj txoj kev xeem rau cov ncauj lus dej hauv emulsified asphalt.
Cov ntsiab lus ntawm cov ntsiab lus thiab cov khoom tau txais los ntawm cov qauv sib txawv ntawm kev tau txais cov nyiaj asphalt yog sib txawv.
Kev tshawb fawb sim tau pom tias txoj kev ziab hauv qhov cub rau ib lub sijhawm feem ntau ua rau cov dej evaprogoration tsis tiav; Lub astm distillation cov txiaj ntsig tau ruaj khov, tab sis vim yog cov cuab yeej kuaj cov khoom sib txawv, tam sim no nyuaj rau kev txhawb nqa hauv kuv lub tebchaws. Txawm hais tias kuv lub teb chaws txoj kev ntawm cov cua kub ncaj qha rau 163 ° C kom tau cov chaw nyob yuav cuam tshuam los ntawm cov neeg nyob ntawm tib neeg, txoj kev sim ua tau yooj yim, thiab nws yog qhov ua tau yooj yim.
