QXME 103P; I-asphalt Emulsifier, i-Hydrogenated Tallow Amine, i-Stearyl Amine

Inkcazelo emfutshane:

Umaleko wokubopha, umaleko wokuqhawuka: i-emulsifier eqinileyo ene-viscosity ephezulu kakhulu enegalelo kuzinzo lokugcinwa kwee-emulsions zeCRS.

Ukuphucula ukuqina kwe-pavement: Njenge-binder kumxube we-asphalt, i-asphalt ye-emulsified ingakwazi ukubopha ngokuqinileyo amaqhekeza amatye kunye nesakhiwo esiqinileyo se-pavement, ukuphucula kakhulu ukuqina kunye nokuxhatshazwa koxinzelelo lwendlela.

I-asphalt ye-Emulsified isetyenziswa ngokubanzi kulwakhiwo lweendlela, ukulungiswa kunye nokwakhiwa kwakhona kweeprojekthi. Ingasetyenziswa njenge-binder kwimixube ye-asphalt ukuze iphucule ngokufanelekileyo ukuqina kunye nokuzinza kwendawo yendlela, ngelixa inciphisa iindleko zokwakha kunye nongcoliseko lokusingqongileyo. Ukongeza, i-asphalt e-emulsified ingasetyenziselwa ukugquma kwamanzi, uphahla lwempahla yokukhusela amanzi kunye netonela yangaphakathi yodonga lwezixhobo zokukhusela amanzi, kunye nokusebenza kakuhle kwamanzi.

Isicelo seMveliso

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 inokugcina inani le-asphalt, yenza lula iinkqubo zokwakha, iphucule iimeko zokwakha, kunye nokunciphisa ukungcola kwindawo engqongileyo. Ngenxa yezi nzuzo, i-asphalt e-emulsified ayifanelekanga kuphela kwiindlela zokuhamba, kodwa kunye nokukhusela i-slope ye-slope e-embankments yokuzalisa, ukuvinjelwa kwamanzi kophahla lwesakhiwo kunye nemiqolomba, i-anticorrosion yomphezulu wezinto zetsimbi, ukuphuculwa komhlaba wezolimo kunye nempilo yezityalo, ibhedi yomzila jikelele kaloliwe, ukulungiswa kwesanti entlango, 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. Inokuthi ibhengezwe 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.
