Emulsified asphalt paving inogadzirwa nemhando yepamusoro emulsifiers inorerutsa pa-saiti kuvaka.Hapana chikonzero chekupisa asphalt kusvika kune yakakwirira ye170 ~ 180 ° C isati yashandiswa.Zvicherwa zvakadai sejecha nematombo hazvidi kuomeswa uye kupisa, izvo zvinogona kuchengetedza mafuta akawanda uye kupisa simba..Nekuti iyo asphalt emulsion ine basa rakanaka, inogona kugoverwa zvakaenzana pamusoro peiyo aggregate uye ine yakanaka adhesion nayo, saka inogona kuchengetedza huwandu hweasphalt, kurerutsa maitiro ekuvaka, kugadzirisa mamiriro ekuvaka, uye kuderedza kusvibiswa kune yakatenderedza. zvakatipoteredza.Nekuda kwemabhenefiti aya, emulsified asphalt haikodzere chete kugadzira migwagwa, asiwo yekudzivirira kwemateru emvura inozadza, kudzivirira mvura kwematenga ezvivakwa nemapako, anticorrosion yepasi yezvinhu zvesimbi, kuvandudzwa kwevhu rekurima uye hutano hwezvirimwa, mubhedha wenjanji, desert sand fixation, etc. Inoshandiswa zvakanyanya mumapurojekiti akawanda.Nekuti emulsified asphalt haingogone kuvandudza tekinoroji yekuvaka yeasphalt inopisa, asi zvakare kuwedzera huwandu hwekushandisa kweasphalt, emulsified asphalt yakagadzira nekukurumidza.
Asphalt emulsifier imhando ye surfactant.Chimiro chayo chemakemikari chine lipophilic uye hydrophilic mapoka.Inogona kushambadzirwa pamusangano pakati peasphalt particles nemvura, nokudaro kuderedza zvakanyanya simba rekusununguka kwehutano pakati peasphalt nemvura, zvichiita kuti ive surfactant inoumba yunifomu uye yakagadzikana emulsion.
Surfactant chinhu chinogona kuderedza zvakanyanya kusimba kwepamusoro pemvura kana yawedzerwa muhushoma, uye inogona kushandura zvakanyanya chimiro chechimiro uye mamiriro ehurongwa, nekudaro ichigadzira wetting, emulsification, kupupa, kugeza, uye kupararira., antistatic, lubrication, solubilization uye nhevedzano yemabasa kusangana nezvinodiwa zvekushandisa zvinoshanda.
Hazvina mhosva kuti ndeupi rudzi rwe surfactant, molecule yayo inogara ichiumbwa ne-non-polar, hydrophobic uye lipophilic hydrocarbon chain chikamu uye polar, oleophobic uye hydrophilic boka.Zvikamu zviviri izvi zvinowanzowanikwa pamusoro.Migumo miviri yeanoshanda agent molecule inoumba asymmetric chimiro.Naizvozvo, iyo molecular chimiro che surfactant inoratidzirwa neamphiphilic molecule iyo iri lipophilic uye hydrophilic, uye ine basa rekubatanidza mafuta nemvura.
Kana ma surfactants akadarika imwe kusungwa mumvura (yakakosha micelle concentration), vanogona kugadzira micelles kuburikidza neiyo hydrophobic athari.Iyo yakakwana emulsifier dosage ye emulsified asphalt yakakura kwazvo kupfuura yakakosha micelle concentration.
