Kukho iintlobo ezimbini eziphambili zeendlela zokuguqulwa kwe-container-type bitumen emulsion plant: indlela yokuxuba yangaphandle kunye nendlela yokuxuba yangaphakathi. Indlela yokuxuba yangaphandle kukuqala ukwenza isixhobo esisisiseko se-emulsion ye-container-uhlobo lwebhitumene, uze udibanise i-polymer latex modifier kwisiseko se-Shanxi isikhongozeli-uhlobo lwe-emulsified bhitumen izixhobo, kwaye udibanise. I-emulsion ye-polymer ngokuqhelekileyo ibonakala njenge-emulsion ye-CR, i-Emulsion ye-SBR kunye ne-emulsions ye-acrylic, njl. Indlela yokuxuba yangaphakathi kukuxuba kuqala irabha, iplastiki kunye nezinye iipolymers kunye nezinye izongezo kwibhitumene enemibala eshushu ebandayo. Emva kokuxuba ngokulinganayo kunye nokuvelisa ukusebenzisana okuthile phakathi kwepolymer kunye ne-bitumen enemibala ebandayo, i-bitumen-modified bitumen ifunyenwe. Emva koko i-emulsion ye-bitumen elungisiweyo iveliswa ngenkqubo ye-emulsification. I-polymer esetyenziswa ngokuqhelekileyo kwindlela yokuxuba yangaphakathi yi-SBS. Ukuba umxube obandayo webhitumene uxutywe kwaye emva koko uvale iyure, hlambulula umphezulu we-barrel yokuxuba, yongeza amanzi, kwaye uhlambe udaka. Emva koko ukhuphe amanzi, ukhumbule ukuba akukho qoqo lamanzi kwibhakethi ukukhusela utshintsho kwiresiphi okanye ukugqwala kwesikhululo kunye nezinye iinkqubo. Xa ubalandela, wonke umntu uyazi ukuba alumke malunga neenkqubo ezininzi ezincinci zokuphepha inkunkuma engafanelekanga emsebenzini.

Izizathu zokuba kutheni izixhobo ze-emulsion zebhitumene zisebenza:
Umonakalo womphezulu woxinzelelo lwesikhongozeli-uhlobo lwesixhobo sebhitumene emulsified kunye namanzi yahluke kakhulu, kwaye azixubeki omnye komnye kumaqondo obushushu aqhelekileyo okanye aphezulu. Xa iplanti yebhitumene yohlobo lwesikhongozeli ifumana ukusebenza kakuhle kwe-centrifugation, ukucheba, impembelelo kunye nezinye izixhobo, isixhobo sohlobo lwebhitumene exutyiweyo siya kuyijika ibe ngamasuntswana angamasuntswana angama-0.1 ~ 5μm, kwaye uwasasaze ukuze aqulathe i-surfactants (emulsifier). I-Stabilizer) kumbindi wamanzi, kuba i-emulsifier inokubhengezwa kumphezulu we-Shanxi emulsified amasuntswana amaziko ebhitumene anombala obandayo axubene abandayo kwiindawo ezimiselweyo, kunciphisa uxinezeleko oluphakathi kobuso phakathi kwamanzi kunye nebhitumene enemibala ebandayo, evumela ukubanda- xuba amasuntswana ebhitumene anemibala ukuze enze emanzini. Ngemigangatho ezinzileyo yokukhutshwa, izixhobo ze-emulsion ze-bitumen ze-container ziyi-emulsion yeoli emanzini. Lo mgangatho wokukhupha umdaka, ibhitumem enemibala exutywe ngokubanda sisigaba esisasaziweyo, amanzi sisigaba esiqhubekayo, kwaye anolwelo oluchanekileyo kubushushu begumbi. Isixhobo sebhitumene efakwe kwisikhongozelo kunye nezibonelelo Ngandlela ithile, izixhobo zebhitumene ezifakwe kwikhonteyina kunye nezibonelelo zisebenzisa amanzi "ukusasaza" ukuxuba ibhitumene enemibala ebandayo, ngaloo ndlela ilungisa ukumanzi kwebhitumene enombala obandayo.
Isixhobo sohlobo lwebhitumene esiludidi lwesikhongozeli sishushu sinyibilikisa ibhitumene enombala obandayo-umxube obandayo kwaye iyisasaze ngesixhobo kumasuntswana amancinane ebhitumene anomxube obandayo anemibala emanzi aqulathe isigqubuthelo sombane ukwenza ulwelo lwebhitumene olunolulwelo oluxubeneyo olubandayo. Isikhongozelo sesamente-uhlobo emulsified isixhobo sebhitumene udaka lwe slab ballastless track ubeko isebenzisa cationic isikhongozeli-uhlobo emulsified isixhobo sebhitumene. Ukuze kulungiswe i-elasticity kunye nokuthembeka kwesitya se-sement-type emulsified bitumen plant mortar, iipolymers zihlala zisetyenziselwa ukuguqula i-bitumen.
