Emulsified asphalt feem ntau yog siv rau kev txhim kho txoj kev thiab kev saib xyuas, xws li pob zeb nti foob, thiab muaj ntau yam kev siv tshwj xeeb uas tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv asphalt, xws li txias sib tov thiab slurry foob. Emulsified asphalt kuj tseem siv tau rau kev tsim kho tshiab, xws li tack coat oil thiab penetration oil.

Dab tsi yog cov yam ntxwv ntawm Gaoyuan hom emulsified asphalt:
1. Kev tsim kho txias yog kev txuag hluav taws xob, kev siv-txo, kev nyab xeeb, ib puag ncig tus phooj ywg, thiab tsis tshua muaj kev txwv los ntawm huab cua.
3. Ntau yam pavement qauv hauv kev tsim kho, kev kho thiab tu.
4. Nws yog ib qho yooj yim los tswj qhov zoo ntawm kev sib kis, muaj peev xwm nkag tau zoo thiab adhesion, thiab tuaj yeem txhim kho txoj kev zoo.
5. Nws zam rov qab cua sov thiab txo qhov poob ntawm asphalt zoo.
Emulsified asphalt muab faib ua cationic emulsified asphalt thiab anionic emulsified asphalt. Cov asphalt hais ntawm cationic emulsified asphalt yog qhov zoo, thiab cov khoom ntawm anionic emulsified asphalt yog qhov tsis zoo. Thaum cationic emulsified asphalt hu rau saum npoo ntawm aggregate, vim cov nqi sib txawv, qhov sib txawv nyiam sib txawv. Nyob rau hauv lub xub ntiag ntawm dej zaj duab xis, cov asphalt hais yuav muab qhwv rau saum npoo ntawm aggregate thiab tseem yuav zoo adsorbed thiab ua ke. Yog li ntawd, nws tseem tuaj yeem tsim tau hauv qhov chaw ntub dej thiab qhov kub thiab txias (siab tshaj 5 ° C). Txawm li cas los xij, anionic emulsified asphalt yog qhov sib txawv. Nws nqa cov nqi tsis zoo rau ntawm qhov chaw ntub dej sib sau ua ke, uas ua rau lawv tawm tsam ib leeg. Asphalt hais tsis tuaj yeem ua raws li qhov sib xyaw ua ke sai. Yog hais tias asphalt hais yuav tsum tau qhwv rau saum npoo ntawm aggregate, cov dej nyob rau hauv lub emulsion yuav tsum tau evaporated. Yog li ntawd, nws yog ib qho nyuaj rau tsim nyob rau hauv lub caij ntuj sov los yog tsis kub.
Thaum cov emulsified asphalt so thiab solidifies - nws yog txo kom nruam asphalt thiab cov dej raug tshem tawm tag, thiab lub zog kawg ntawm txoj kev cov ntaub ntawv yuav tsim.
Hloov kho emulsified asphalt yog cov kua asphalt tsim los ntawm asphalt thiab emulsifier nyob rau hauv qee cov txheej txheem nrog latex. Qhov txawv ntawm kev hloov kho emulsified asphalt thiab emulsified asphalt yog seb latex ntxiv thaum lub sij hawm tsim khoom.
Qhov ruaj khov emulsion tau los ntawm uniformly dispersing asphalt hais nyob rau hauv ib tug aqueous tov uas muaj ib tug emulsifier.
Lub luag haujlwm ntawm Gaoyuan hom cationic emulsified asphalt:
Emulsified asphalt feem ntau yog siv rau kev txhim kho txoj kev thiab kev saib xyuas, xws li pob zeb nti foob, thiab muaj ntau yam kev siv tshwj xeeb uas tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv asphalt, xws li txias sib tov thiab slurry foob. Emulsified asphalt kuj tseem siv tau rau hauv kev tsim kho tshiab, xws li tack coat oil, penetration coat oil, thiab lwm yam.
