QXME 103P; Emulsifier Asphalt, Hydrogenated Tallow Amine, Stearyl Amine

Sharaxaad Gaaban:

Lakabka xidhi, lakabka la gooyo: emulsifier adag leh gaar ahaan viscosity sare oo gacan ka geysta xasiloonida kaydinta emulsions CRS.

Hagaajinta cimriga laamiga: Sida xidheha isku dhafka daamurka, daamurka emulsified wuxuu si adag isugu xidhi karaa qaybaha dhagxaanta si ay u sameeyaan qaab dhismeed adag oo laami ah, si weyn u wanaajiya adkaysiga iyo iska caabinta cadaadiska ee laamiga.

Daamurka Emulsified ayaa si weyn loogu isticmaalaa dhismaha waddooyinka, dayactirka iyo mashaariicda dib u dhiska. Waxa loo isticmaali karaa sida xidhe ee isku dhafka asphalt si wax ku ool ah loo hagaajiyo adkeysiga iyo xasiloonida ee dusha wadada, iyada oo sidoo kale la yareeyo kharashka dhismaha iyo wasakhowga deegaanka. Intaa waxaa dheer, daamurka emulsified waxa kale oo loo isticmaali karaa sida dahaarka biyuhu, alaabta saqafka ilaalinta iyo tunnel gudaha alaabta biyuhu, oo leh waxqabad aad u fiican biyuhu.

Codsiga Alaabta

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 asphalt wuxuu leeyahay karti shaqo oo wanaagsan, si siman ayaa loo qaybin karaa dusha sare ee isku-darka wuxuuna leeyahay adhesion wanaagsan, sidaas darteed waxay badbaadin kartaa qadarka asphalt, fududaynta hababka dhismaha, hagaajinta xaaladaha dhismaha, iyo yaraynta wasakheynta deegaanka ku xeeran. Sababo la xiriira faa'iidooyinka, kuwaas oo, daamur emulsified ma aha oo kaliya ku habboon waddooyinka laami, laakiin sidoo kale ee ilaalinta jiirada ah ee daboolka buuxinta, biyo-ilaalinta ee saqafyada dhismaha iyo godadka, anticorrosion dusha ee alaabta biraha, horumarinta ciidda beeraha iyo caafimaadka dhirta, sariirta guud sariirta tareenada, saxaraha ciidda saxaraha ah, iwm Waxaa si ballaaran loo isticmaalaa in 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, laami emulsified 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 aad ah u yareyn karta culeyska 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 qayb silsilad hydrocarbon lipophilic iyo polar ah, oleophobic iyo hydrophilic group. Labadan qaybood waxay inta badan ku yaalaan 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.
