Raws li tus pib hauv txoj kev loj ntawm kev lag luam kev lag luam, niaj hnub no peb yuav kawm txog qhov sib txawv ntawm emulsified asphalt thiab hloov asphalt uas peb feem ntau siv hauv kev tsim kho tshiab.
Ua ntej tshaj plaws, qhov pom tseeb ntawm emulsified asphalt thiab hloov asphalt yog tias evulsified asphalt muaj dej, thaum hloov asphalt tsis.
Emulsified asphalt disperses kub asphalt rau hauv dej (roj hauv dej) lossis dej rau hauv roj) los ntawm emulsifier los ua ib qho kev ruaj khov uas emulsion ib ntus. Cov theem nruam yog dej thiab cov theem dispersed yog asphalt. Asphalt cov khoom ua kom tawv nqaij-zoo li cov khoom siv ntawm chav tsev kub thiab kua zoo li cov khoom kub ntawm qhov kub. Yog li ntawd, tom qab tom qab tom qab asphalt yog dispersed hauv dej, nws tuaj yeem siv nyob rau hauv chav tsev kub, uas yog qhov loj tshaj plaws kom zoo dua ntawm emulsified asphalt. Nyob rau hauv ib lo lus, asphalt rhuab mus ua kua yog tov nrog ib tug emulsifier, stabilizer, kua qaub los yog alkali los ntawm ib lub zeb devolhalt.

Hloov asphalt yog yooj yim. Peb hu rau Pairphalt Matrix aspix aspix aspix aspix aspix aspix aspix aspix aspects, yog li ntxiv cov hloov kho rau cov ntawv aspifier ua ke ua tiav kev hloov siab. Raws li hom hloov kho, nws tau muab faib ua ke, xws li SBS hloov asphalt, sbr hloov asphalt thiab lwm yam hva siab viscosity; Ntuj Asphalt Kev Hloov, xws li Trinidad Lake asphalt, Buton POBZEB ROJBH, thiab lwm yam; Qee qhov kev tshawb fawb tau hais txog Inorganic tsis yog xim hlau cov khoom hloov kho, xws li Bentonite kev hloov kho. Txawv ntau hom qauv hloov kho tuaj yeem hloov pauv cov khoom ntawm asphalt. Piv txwv li, SBS tuaj yeem nce kev ductility ntawm lub hauv paus rau ntau tshaj li 1.5 meters. Qhov kev xav paub tab yog cov asphalt tuaj yeem kos rau hauv xov. Peb tuaj yeem xaiv cov hloov asphalt uas haum rau peb raws li peb cov haujlwm ua haujlwm.
Qhov tseeb, emulsified asphalt thiab hloov asexhalt tuaj yeem ua tub ntxhais, tab sis cov qauv kev faib tawm txawv. Piv txwv li, SBS hloov asphalt yog emulsified kom tau txais sbs hloov emulsified ayhalt; SBR 400 tau ntxiv rau qhov zoo tib yam omulsified kom tau sbr hloov emulsified evult.
Kev ua txhaum pawg neeg tau ua haujlwm tau koom nrog kev saib xyuas txoj kev loj tau ntau xyoo thiab kev tsim kho kev tsim kho. Nws United Txoj Haujlwm Kev Kho Vajtse xws li Micro-Surfacing, Slurry Sealing, Potting Secoringing, Gravel Sealing, permeable txheej | Adhesive Txheej Siv, thiab lwm yam, thiab muag emulsified asphalt cov khoom siv ntau lawm, slurry sealing machine, synchronous gravel sealing machine thiab lwm yam khoom txij nkawm. Peb lub tuam txhab tseem ua cov asphaltifyifiers thiab muaj feem cuam tshuam txog kev phem asphalt haum rau micro-surfacing, slurry sealing thiab lwm yam kev ua haujlwm. Cov neeg siv khoom tshiab thiab qub tau txais tos hu rau peb rau kev sab laj!
