Slurry sealing siv cov khoom siv txhua yam kom sib xyaw ua ke nrog cov txheej txheem qub los ntawm kev sib xyaw ua ke, thiab lwm yam (cement ntom, muaj zog, hnav-resistant thiab txoj kev npoo npoo, uas tau txhim kho cov kev ua tau zoo ntawm txoj kev saum npoo.
Slurry sealing thev naus laus zis tawm hauv lub teb chaws Yelemees nyob rau xyoo 1940. Hauv Tebchaws Asmeskas, daim ntawv thov ntawm Slurry Sealant cov nyiaj rau 60% ntawm lub teb chaws cov av dub, thiab nws cov kev siv tau nthuav dav. Nws yog lub luag haujlwm hauv kev tiv thaiv thiab kev kho cov kab mob xws li kev laus, kev tiv thaiv, kev tiv thaiv, du thiab hnav-resistant yam ntxwv ntawm txoj kev nto tau txhim kho sai heev.
Slurry sealing tseem yog ib txoj kev tiv thaiv kev tsim kho rau kev kho kom ntev rau saum npoo av. Cov ntawv asphalt qub feem ntau muaj cov kab nrib pleb thiab cov kab mob. Thaum cov npoo hnav, emulsified asphalt slurry sib tov sib xyaw kom sai li sai tau, yog li hais tias asphalt pob zeb ua kom muaj peev xwm tswj tau. Nws yog txij nkawm thiab kho nrog lub hom phiaj ntawm kev rov qab ua haujlwm ntawm txoj kev saum npoo thiab tiv thaiv kev puas tsuaj ntxiv.

Qaum qeeb tawg lossis nruab nrab tawg sib xyaw emulsified txheej txheej yuav tsum muaj txog li 60%, thiab qhov tsawg kawg nkaus yuav tsum tsis pub tsawg tshaj li 55%. Feem ntau, anionic emulsified ashrhalt muaj cov nplaum tsis zoo rau cov khoom siv ntxhia thiab siv sijhawm ntev los ua. Nws yog feem ntau siv rau alkaline aggregates, xws li limestone. Cationic emulsified ashesion ua kua nplaum zoo rau cov accidic agerregates thiab feem ntau siv nyob rau hauv acidic agregates, xws li cov hauv paus acidegates, xws li basalt, granite, thiab lwm yam.
Kev xaiv ntawm asphalt emulsifier, ib qho ntawm cov khoom xyaw hauv emulsified asphalt, yog qhov tshwj xeeb. Ib qho zoo asphalt emulsifier tsis tuaj yeem tsuas yog ua kom zoo ntawm kev tsim kho tab sis kuj txuag tau tus nqi. Thaum xaiv, koj tuaj yeem xa mus rau ntau qhov ntsuas ntawm asphalt emulsifiers thiab cov lus qhia rau kev siv cov khoom sib xws. Peb lub tuam txhab ua ntau yam ntawm ntau lub hom phiaj evultifiers. Yog koj muaj lus nug, thov sab laj peb cov neeg siv khoom.
Lub emulsified asphalt slurry foob yuav siv tau rau kev saib xyuas kev saib xyuas ntawm chav kawm, thiab tseem muaj txoj kev loj ntawm cov txheej txheej lossis txheej txheem tiv thaiv ntawm txoj kev loj tshiab. Tam sim no tseem siv rau txoj kev loj.
Kev faib tawm ntawm Swb Cov Ntsaws:
Raws li kev kawm tiav pob zeb
Raws li cov txheej txheem ntxhia, cov slurry sealing txheej txheej, nruab nrab ntawm cov txheej sib xyaw ua ke, nruab nrab ntawm cov txheej txheem ntawm lawv, tus sawv cev ntawm ES-1, ES-2 thiab ES-3 feem.
Raws li kev ceev ntawm kev qhib rau kev ua haujlwm
Raws li kev ceev ntawm kev qhib tsheb khiav tawm [1], Slurry Ntsaws tuaj yeem muab faib ua cov tsheb ciav hlau Slurry Slurry Ntsaws Ruaj Ruaj.
Muab faib ua ntej polymer modifiers tau ntxiv
Raws li kev hloov kho polymer yog ntxiv, slurry sealing txheej txheej tuaj yeem muab faib ua slurry sealing txheej thiab hloov slurry sealing txheej txheej.
Muab faib raws cov khoom sib txawv ntawm emulsified asphalt
Slurry sealing txheej tau muab faib ua ke rau hauv slurry seeding txheej txheej thiab hloov slurry sealing txheej txheej ntawm emulsified asphalt.
Muab faib raws li thickness
Raws li cov tuab sib txawv, nws tau muab faib ua cov txheej zoo (i txheej), nruab nrab hom) thiab tuab sealing txheej (IV hom).
