Ukugandaywa kwe-asphalt emulsified okukhiqizwe ngezifanisi ezisezingeni eliphezulu kwenza ukwakhiwa kwendawo kube lula.Asikho isidingo sokushisa i-asphalt ekushiseni okuphezulu kwe-170 ~ 180 ° C ngaphambi kokusetshenziswa.Izinto zamaminerali ezifana nesihlabathi namatshe azidingeki ukuba zomiswe futhi zishiswe, ezingangonga uphethiloli omkhulu namandla okushisa..Ngenxa yokuthi i-asphalt emulsion inokusebenza okuhle, ingasatshalaliswa ngokulinganayo ebusweni beqoqo futhi inokunamathela okuhle kuyo, ngakho-ke ingakwazi ukonga inani letiyela, yenze lula izinqubo zokwakha, ithuthukise izimo zokwakha, futhi inciphise ukungcoliswa kwendawo ezungezile. imvelo.Ngenxa yalezi zinzuzo, i-asphalt e-emulsified ayifanele kuphela ukugandaywa kwemigwaqo, kodwa futhi nokuvikelwa kwemithambeka yokugcwalisa izigxobo, ukuvimbela amanzi ophahleni lwezakhiwo nemigede, i-anticorrosion ebusweni bezinto zensimbi, ukuthuthukiswa kwenhlabathi yezolimo kanye nempilo yezitshalo, umbhede wesitimela jikelele, ukulungiswa kwesihlabathi sasogwadule, njll. Kusetshenziswa kabanzi kumaphrojekthi amaningi.Ngenxa yokuthi i-asphalt e-emulsified ayikwazi nje ukuthuthukisa ubuchwepheshe bokwakhiwa kwe-asphalt eshisayo, kodwa futhi yandise ububanzi besicelo se-asphalt, i-asphalt e-emulsified ithuthuke ngokushesha.
I-asphalt emulsifier wuhlobo lwe-surfactant.Isakhiwo saso samakhemikhali siqukethe amaqembu e-lipophilic nama-hydrophilic.Ingakhangiswa ku-interface phakathi kwezinhlayiya ze-asphalt namanzi, ngaleyo ndlela yehlise kakhulu amandla wamahhala we-interface phakathi kwe-asphalt namanzi, okwenza kube i-surfactant eyenza i-emulsion efanayo futhi ezinzile.
I-Surfactant iyinto enganciphisa ngokuphawulekayo ukushuba kwesimo samanzi lapho ingezwe ngenani elincane, futhi ingashintsha ngokuphawulekayo izakhiwo zesixhumi esibonakalayo nesimo sohlelo, ngaleyo ndlela ikhiqize ukumanzisa, ukucwilisa, ukugwaza, ukuwasha, nokuhlakazeka., i-antistatic, i-lubrication, i-solubilization kanye nochungechunge lwemisebenzi ukuhlangabezana nezidingo zezinhlelo zokusebenza ezingokoqobo.
Kungakhathaliseki ukuthi hlobo luni lwe-surfactant, i-molecule yayo ihlale yakhiwe ingxenye ye-non-polar, i-hydrophobic kanye ne-lipophilic hydrocarbon chain kanye neqembu le-polar, i-oleophobic ne-hydrophilic.Lezi zingxenye ezimbili zivame ukuba phezulu.Iziphetho ezimbili ze-molecule ye-ejenti esebenzayo zakha isakhiwo se-asymmetric.Ngakho-ke, isakhiwo samangqamuzana e-surfactant sibonakala nge-amphiphilic molecule kokubili i-lipophilic ne-hydrophilic, futhi inomsebenzi wokuxhuma izigaba zamafutha namanzi.
Uma ama-surfactants edlula ukuhlushwa okuthile emanzini (i-critical micelle concentration), angakha ama-micelles ngomphumela we-hydrophobic.Umthamo we-emulsifier olungile we-asphalt e-emulsified mkhulu kakhulu kunokugxilisa okubalulekile kwe-micelle.
