CAS Nr .: 7173-62-8, QXME 24;Asphalt Emulsifier, Oleyl Diamine
Cov txiaj ntsig thiab nta
● Qib siv tsawg.
0.18-0.25% feem ntau yog txaus rau ceev-teeb emulsions.
● High emulsion viscosity.
Emulsions npaj siv QXME 24 muaj viscosities ntau dua, uas tso cai rau cov ntsiab lus kom tau raws li qhov tsawg kawg nkaus asphalt ntsiab lus.
● Ceev nrawm.
Emulsions npaj nrog QXME 24 qhia nrawm nrawm hauv thaj teb txawm tias qhov kub thiab txias.
● Yooj yim tuav thiab khaws cia.
QXME 24 yog kua, thiab yooj yim yaj hauv dej sov thaum lub sij hawm npaj emulsion xab npum theem.Cov khoom tsim nyog rau ob qho tib si hauv kab thiab batch nroj tsuag.
Cia thiab tuav.
QXME 24 tej zaum yuav khaws cia rau hauv cov pa roj carbon steel tso tsheb hlau luam.
Kev khaws cia ntau yuav tsum khaws cia ntawm 15-35 ° C (59-95 ° F).
QXME 24 muaj amines thiab corrosive rau daim tawv nqaij thiab qhov muag.Cov tsom iav thiab hnab looj tes tiv thaiv yuav tsum hnav thaum tuav cov khoom no.

Tsis muaj teeb meem dab tsi ntawm surfactant, nws cov molecule yog ib txwm tsim los ntawm cov tsis muaj polar, hydrophobic thiab lipophilic hydrocarbon saw ib feem thiab ib pawg polar, oleophobic thiab hydrophilic.Ob qho no feem ntau nyob ntawm qhov chaw.Ob qhov kawg ntawm tus neeg sawv cev molecule tsim ib qho qauv asymmetric.Yog li ntawd, cov qauv molecular ntawm surfactant yog tus cwj pwm los ntawm amphiphilic molecule uas yog lipophilic thiab hydrophilic, thiab muaj kev ua haujlwm ntawm kev sib txuas cov roj thiab dej theem.
Thaum cov surfactants ntau tshaj qhov concentration hauv dej (qhov tseem ceeb micelle concentration), lawv tuaj yeem tsim micelles los ntawm cov nyhuv hydrophobic.Qhov zoo tshaj plaws emulsifier ntau npaum li cas rau emulsified asphalt yog ntau dua li qhov tseem ceeb micelle concentration.
