I-asphalt egayiweyo eyenziwe nge-emulsified eveliswe nge-emulsifiers ekumgangatho ophezulu yenza lula ukwakhiwa kwendawo.Akukho mfuneko yokutshisa i-asphalt kwiqondo lokushisa eliphezulu le-170 ~ 180 ° C ngaphambi kokusetyenziswa.Izinto zeminerali ezifana nesanti kunye negrabile akufuneki ukuba zomiswe kwaye zifudunyezwe, ezinokonga umbane omkhulu kunye namandla obushushu..Ngenxa yokuba i-emulsion ye-asphalt inokusebenza kakuhle, inokusasazwa ngokulinganayo kumphezulu we-aggregate kwaye inamathele kakuhle kuyo, ngoko inokonga ubungakanani be-asphalt, yenza lula iinkqubo zokwakha, iphucule iimeko zokwakha, kunye nokunciphisa ungcoliseko kwiindawo ezingqongileyo. okusingqongileyo.Ngenxa yolu ncedo, i-asphalt e-emulsified ayifanelekanga kuphela kwiindlela zokuhamba, kodwa kunye nokukhuselwa kwethambeka lokuzaliswa kwee-embankments, ukukhuselwa kwamanzi kuphahla lwezakhiwo kunye nemiqolomba, i-anticorrosion yomhlaba wezinto zetsimbi, ukuphuculwa komhlaba wezolimo kunye nempilo yezityalo, ibhedi epheleleyo yomzila kaloliwe, ukulungiswa kwesanti yasentlango, njl. Isetyenziswa ngokubanzi kwiiprojekthi ezininzi.Ngenxa yokuba i-asphalt e-emulsified ayikwazi nje ukuphucula itekhnoloji yokwakha ye-asphalt eshushu, kodwa yandisa umda wesicelo se-asphalt, i-asphalt e-emulsified iphuhliswe ngokukhawuleza.
I-asphalt emulsifier luhlobo lwe-surfactant.Ubume bayo beekhemikhali buqukethe amaqela e-lipophilic kunye ne-hydrophilic.Iyakwazi ukubhengezwa kwi-interface phakathi kwamasuntswana e-asphalt kunye namanzi, ngaloo ndlela inciphisa kakhulu amandla asimahla onxibelelwano phakathi kwe-asphalt kunye namanzi, okwenza i-surfactant eyenza i-emulsion efanayo kunye nezinzile.
I-Surfactant yinto enokunciphisa kakhulu ukuxinana komphezulu wamanzi xa ifakwe kwisixa esincinci, kwaye inokutshintsha ngokubonakalayo iipropathi zojongano kunye nemeko yenkqubo, ngaloo ndlela ivelise ukumanzisa, i-emulsification, ugwebu, ukuhlamba, kunye nokusasazeka., i-antistatic, i-lubrication, i-solubilization kunye noluhlu lwemisebenzi ukuhlangabezana neemfuno zezicelo eziphathekayo.
Kungakhathaliseki ukuba luhlobo luni lwe-surfactant, i-molecule yayo ihlala iqulunqwe yi-non-polar, i-hydrophobic kunye ne-lipophilic hydrocarbon chain part kunye ne-polar, i-oleophobic kunye neqela le-hydrophilic.Ezi nxalenye zimbini zihlala zibekwe phezu komhlaba.Iziphelo ezimbini ze-agent esebenzayo zenza i-asymmetric structure.Ngoko ke, i-molecular structure ye-surfactant ibonakaliswe yi-amphiphilic molecule ene-lipophilic kunye ne-hydrophilic, kwaye inomsebenzi wokudibanisa izigaba zeoli kunye namanzi.
Xa i-surfactants idlula i-concentration ethile emanzini (i-critical micelle concentration), inokwenza i-micelles ngokusebenzisa i-hydrophobic effect.Elona thamo lifanelekileyo lokumisela i-asphalt e-emulsified likhulu kakhulu kunoxinaniso olubalulekileyo lwemicelle.
