Daamur laami ah oo la soo saaray oo leh emulsifiers tayo sare leh ayaa fududeynaya dhismaha goobta.Looma baahna in lagu kululeeyo asphalt-ka heerkul sare oo ah 170 ~ 180 ° C kahor isticmaalka.Walxaha macdanta sida ciidda iyo jayga looma baahna in la qalajiyo oo la kululeeyo, taas oo badbaadin karta shidaal badan iyo tamarta kulaylka..Sababtoo ah emulsion-ka asphalt wuxuu leeyahay karti shaqo oo wanaagsan, si siman ayaa loo qaybin karaa dusha sare ee wadarta oo uu leeyahay adhesion wanaagsan, sidaas darteed waxay badbaadin kartaa qadarka asphalt, fududaynta hababka dhismaha, hagaajinta xaaladaha dhismaha, iyo yaraynta wasakhda agagaarka agagaarka deegaanka.Sababo la xiriira faa'iidooyinka, kuwaas oo, daamur emulsified ma aha oo kaliya ku habboon waddooyinka laami, laakiin sidoo kale ee ilaalinta jiirada ee rarramada buuxinta, biyo-ilaalinta ee saqafyada dhismaha iyo godadka, anticorrosion dusha ee alaabta biraha, horumarinta ciidda beeraha iyo caafimaadka dhirta, sariirta guud sariirta tareenada. hagaajinta ciidda saxaraha ah, iwm. Waxaa si weyn loogu isticmaalaa mashaariic badan.Sababtoo ah daamurka emulsified ma aha oo kaliya hagaajin karo farsamada dhismaha ee daamurka kulul, laakiin sidoo kale ballaariyo baaxadda codsiga ee asphalt, emulsified laami ayaa si degdeg ah u horumaray.
Emulsifier Asphalt waa nooc ka mid ah surfactant.Qaab dhismeedka kiimikada wuxuu ka kooban yahay kooxo lipophilic iyo hydrophilic.Waxaa lagu dhejin karaa isdhexgalka u dhexeeya qaybaha daamurka iyo biyaha, taas oo si weyn u yaraynaysa tamarta bilaashka ah ee isdhexgalka u dhexeeya daamurka iyo biyaha, taas oo ka dhigaysa surfactant kaas oo sameeya emulsion isku mid ah oo deggan.
Surfactant waa walax si weyn u yarayn karta xiisadda dusha sare ee biyaha marka lagu daro qadar yar, waxayna si weyn u bedeli kartaa sifooyinka interface iyo xaaladda nidaamka, taas oo soo saarta qoynta, emulsification, xumbo, dhaqid, iyo kala firdhiso., antistatic, lubrication, solubilization iyo taxane ah oo hawlaha si ay u buuxiyaan shuruudaha codsiyada la taaban karo.
Si kastaba ha ahaatee nooca surfactant, molecule ay had iyo jeer ka kooban yahay non-polar, hydrophobic iyo lipophilic qayb silsilad hydrocarbon iyo polar ah, oleophobic iyo hydrophilic group.Labadan qaybood ayaa inta badan ku yaal dusha sare.Labada daraf ee molecule wakiilka firfircoon waxay sameeyaan qaab-dhismeed asymmetric ah.Sidaa darteed, qaab-dhismeedka molecular ee surfactant waxaa lagu gartaa molecule amphiphilic ah oo labadaba ah lipophilic iyo hydrophilic, oo leh shaqada isku xirka wejiyada saliidda iyo biyaha.
Marka surfactants-ku dhaafo xaddi gaar ah oo biyaha ah (fiirsashada micele ee muhiimka ah), waxay samayn karaan micelle iyada oo loo marayo saamaynta hydrophobic.Qiyaasta emulsifier-ka ugu wanagsan ee daamurka emulsified ayaa aad uga weyn diiradda micele ee muhiimka ah.
