Kukho iindlela ezimbini eziphambili zokuguqulwa kwezixhobo ze-bitumen emulsified: indlela yokuxuba yangaphandle kunye nendlela yokuxuba yangaphakathi. Indlela yokuxuba yangaphandle kukuqala ukwenza isityalo sebhitumene esiqhelekileyo se-emulsified, emva koko udibanise izilungisi ze-polymer latex kwisixhobo esiqhelekileyo se-Emulsified bhitumen ye-Shanxi, kwaye udibanise kwaye uvuselele ukulungiselela. I-emulsions ye-polymer idla ngokuba yi-CR emulsions, i-emulsions ye-SBR, kunye ne-emulsions ye-acrylic. Indlela yokuxuba yangaphakathi kukuqala ukuxuba irabha, iplastiki kunye nezinye iipolymers kunye nezinye izongezo kwibhitumene enemibala eshushu kunye nebandayo. Emva kokuxuba kunye nokulinganisa, kunye nokubonisa impembelelo ehambelanayo phakathi kwepolymer kunye ne-bitumen enemibala ebandayo, i-bitumen eguqulwe nge-polymer ifunyenwe. , kwaye kamva i-emulsion yebhitumene elungisiweyo ilungiswa ngeteknoloji ye-emulsification. I-polymer esetyenziswa ngokuqhelekileyo kwindlela yokuxuba yangaphakathi yi-SBS. Ukuba umxube obandayo webhitumene umisiwe kwiyure emva kokuvuselela, hlambulula umphezulu we-barrel ephazamisayo, yongeza amanzi acocekileyo, kwaye uhlambulule udaka. Dwelisa amanzi kamva, kwaye ukhumbule ukuba akukho mfumba kwamanzi kwi-emele ukuthintela ummiselo ekutshintsheni, okubangela ukuba iforamu kunye nezinye iindlela zibonakale zinomhlwa. Xa uyisebenzisa ngokuhambelana nemiyalelo, kufuneka uthathe amanyathelo alula ukuze ugweme ilahleko engeyomfuneko ekusebenzeni.

Umgaqo osebenzayo we-emulsion bitumen isixhobo:
Amandla oxinzelelo lomphezulu wesixhobo sebhitumene emulsion kunye namanzi ahluke kakhulu, kwaye awaxubeki omnye komnye kumaqondo obushushu aqhelekileyo okanye aphezulu. Xa isityalo se-emulsion ye-bitumen siphantsi kweempawu zomatshini ezifana ne-centrifugation ngokukhawuleza, ukucheba, kunye nefuthe, izixhobo ze-emulsion ze-bitumen ziya kuguquka zibe ngamaqhekeza kunye nobukhulu be-particle ye-0.1 ~ 5 μm, kwaye zihlakazeke kwindawo apho kungekho surfactant ( emulsifier-stabilizer) Kumbindi wamanzi, kuba isisinyisi singabhengezwa kumphezulu we-Shanxi emulsified amasuntswana ebhitumene anemibala ebandayo-xuba abandayo kwiindawo ezisisigxina, ukunyathelana kobuso phakathi kwamanzi kunye nomxube obandayo webhitumene enombala kucuthiwe, ukuze ukubanda- xuba amasuntswana ebhitumene anemibala anokwenza inkqubo ethe saa ezinzileyo emanzini. , i-emulsion ye-bitumen yesixhobo sokumisela i-emulsion yeoli emanzini. Inkqubo esasazekileyo enjalo inombala omdaka, kunye nebhitumene enemibala edibeneyo ebandayo njengesigaba esisasaziweyo kunye namanzi njengesigaba esiqhubekayo, kwaye inomanzi kakuhle kwiqondo lokushisa. Ufakelo lwezixhobo zebhitumene ye-emulsion Ngandlel 'ithile, izixhobo zebhitumene ze-emulsion zisetyenziselwa "ukusasaza" ukuxuba ibhitumene enemibala ebandayo emanzini, ngaloo ndlela kuququzelela ubumanzi bebhitumene enemibala ebandayo.

Isityalo sebhitumene esakhiweyo sishushu sinyibilikisa ibhitumene enombala obandayo, size ke sisasaze amasuntswana ebhitumene anombala oxutywe kancinane kumxube omanzi oqulathe umgqugquzeli ngomatshini ukwenza amaphepha ebhitumene elulwelo axutywe nemibala ebandayo. Udaka lwesixhobo sebhitumene emulsified emulsified esetyenziselwa slab ballastless track isakhiwo isebenzisa cationic emulsion isityalo sebhitumene. Ukuze ulungelelanise u-elasticity, ukuqina kunye nomgangatho we-cement emulsified bitumen izixhobo zodaka, iipolymers zihlala zisetyenziselwa ukuguqula i-bitumen.
