Emulsified asphalt paving yomwe imapangidwa ndi ma emulsifiers apamwamba kwambiri imathandizira kumanga pamalowo.Palibe chifukwa chotenthetsera phula ku kutentha kwakukulu kwa 170 ~ 180 ° C musanagwiritse ntchito.Zipangizo zamchere monga mchenga ndi miyala siziyenera kuuma ndi kutenthedwa, zomwe zingapulumutse mafuta ambiri ndi mphamvu zotentha..Chifukwa emulsion ya phula imakhala ndi ntchito yabwino, imatha kugawidwa mofanana pamtunda wa aggregate ndipo imakhala yomatira bwino, kotero imatha kupulumutsa phula, kuchepetsa njira zomanga, kukonza zinthu zomanga, ndi kuchepetsa kuipitsidwa kwa malo ozungulira. chilengedwe.Chifukwa cha zabwino izi, phula lopangidwa ndi emulsified siloyenera kupaka misewu yokha, komanso kuteteza malo otsetsereka a mizati yodzaza, kutsekereza madzi a madenga ndi mapanga, anticorrosion pamwamba pazitsulo zachitsulo, kukonza nthaka yaulimi ndi thanzi la zomera, bedi lonse la njanji, kukonzanso mchenga wa m'chipululu, etc. Amagwiritsidwa ntchito kwambiri muzinthu zambiri.Chifukwa phula lopangidwa ndi emulsified silingangowonjezera luso la zomangamanga la phula lotentha, komanso kukulitsa kuchuluka kwa phula, phula lopangidwa ndi emulsified likukula mwachangu.
Asphalt emulsifier ndi mtundu wa surfactant.Mapangidwe ake amapangidwa ndi magulu a lipophilic ndi hydrophilic.Ikhoza kusindikizidwa pa mawonekedwe pakati pa phula ndi madzi, potero kuchepetsa mphamvu yaulere ya mawonekedwe pakati pa phula ndi madzi, ndikupangitsa kuti ikhale yopangidwa ndi surfactant yomwe imapanga emulsion yofanana ndi yokhazikika.
Surfactant ndi chinthu chomwe chimatha kuchepetsa kwambiri kuthamanga kwa madzi pamene chiwonjezedwa pang'ono, ndipo chimatha kusintha kwambiri mawonekedwe ndi mawonekedwe a dongosolo, potero kutulutsa kunyowa, emulsification, thovu, kutsuka, ndi kubalalitsidwa., antistatic, lubrication, solubilization ndi mndandanda wa ntchito kuti akwaniritse zofunikira za ntchito zothandiza.
Ziribe kanthu mtundu wanji wa surfactant, molekyu yake nthawi zonse imakhala ndi gawo lopanda polar, hydrophobic ndi lipophilic hydrocarbon chain ndi gulu la polar, oleophobic ndi hydrophilic.Zigawo ziwirizi nthawi zambiri zimakhala pamtunda.Mapeto awiri a molekyulu yogwira ntchito amapanga mawonekedwe asymmetric.Choncho, mawonekedwe a maselo a surfactant amadziwika ndi molekyulu ya amphiphilic yomwe ili lipophilic ndi hydrophilic, ndipo imakhala ndi ntchito yogwirizanitsa magawo a mafuta ndi madzi.
Pamene surfactants upambana ndende ina m'madzi (ovuta micelle ndende), iwo akhoza kupanga micelles mwa hydrophobic kwenikweni.Mlingo woyenera kwambiri wa emulsifier wa phula lopangidwa ndi emulsified ndi wokulirapo kuposa kuchuluka kwa micelle.
