Kuneziteshi ezimbili eziyinhloko zokuguqula imishini yebitumen e-emulsified: indlela yokuxuba yangaphandle kanye nendlela yokuxuba yangaphakathi. Indlela yokuxuba yangaphandle iwukwenza kuqala isitshalo esijwayelekile sebitumen esine-emulsified, bese wengeza izishintshi ze-polymer latex emshinini ojwayelekile webitumen we-Shanxi emulsified, bese uxuba futhi ugovuze ukuze ulungiselele. Ama-emulsion we-polymer ngokuvamile ama-emulsions e-CR, ama-emulsions e-SBR, nama-emulsions e-acrylic. Indlela yokuxuba yangaphakathi eyokuqala ixube irabha, ipulasitiki namanye ama-polymer nezinye izithasiselo zibe itiyela elinemibala elishisayo nelibandayo. Ngemva kokuxuba nokulinganisa, nokubonisa ithonya elihlobene phakathi kwe-polymer kanye nebitumen enombala oxube abandayo, i-bitumen eguqulwe nge-polymer iyatholakala. , futhi kamuva i-emulsion yebitumen eguquliwe yenziwa ngezifiso ngobuchwepheshe be-emulsification. I-polymer evame ukusetshenziswa endleleni yokuxuba yangaphakathi yi-SBS. Uma ingxube ebandayo yebitumen imiswa ihora ngemuva kokunyakaziswa, hlanza ingaphezulu lomgqomo onyakazayo, engeza amanzi ahlanzekile, futhi uhlanze udaka. Faka ohlwini amanzi kamuva, futhi ukhumbule ukuthi awekho amanzi anqwabelene ebhakedeni ukuvimbela incwadi kadokotela ekushintsheni, okubangela ukuthi inkundla nezinye izindlela zibonakale zigqwalile. Uma uyisebenzisa ngokuhambisana nemiyalelo, kufanele uthathe izinyathelo ezilula zokugwema ukulahlekelwa okungadingekile ekusebenzeni.

Isimiso sokusebenza se-emulsion bitumen imishini:
Amandla okuqina angaphezulu okusebenza kwe-emulsion bitumen namanzi ahluke kakhulu, futhi awahlangani emazingeni okushisa avamile noma aphezulu. Lapho i-emulsion bitumen plant ingaphansi kwezakhiwo zomshini ezifana ne-centrifugation esheshayo, ukugunda, kanye nomthelela, umshini webitumen we-emulsion uzoshintsha ube yizinhlayiyana ezinosayizi wezinhlayiyana ze-0.1 ~ 5 μm, futhi zihlakazeke lapho kungekho khona i-surfactant ( emulsifier-stabilizer) Emkhatsini wamanzi, ngenxa yokuthi i-emulsifier ingakhangiswa phezu kwezinhlayiya zetiyela ezinombala ezixube ezibandayo ze-Shanxi ezindaweni ezingaguquki, ukungezwani kobuso phakathi kwamanzi netiyela elinemibala exube abandayo kunciphe, ukuze ukubanda- hlanganisa izinhlayiya zetiyela ezinombala zingakha uhlelo oluzinzile oluhlakazekile emanzini. , ukulungiselelwa kwemishini yebitumen ye-emulsion i-emulsion yamafutha emanzini. Isistimu ehlakazekile enjalo insundu ngombala, nebitumen enombala oxutshwe namakhaza njengesigaba esihlakazekile namanzi njengesigaba esiqhubekayo, futhi inoketshezi oluhle ekamelweni lokushisa. Ukufakwa kwempahla yebitumen ye-emulsion Ngomqondo othile, okokusebenza kwebitumen emulsion kusetshenziselwa "ukuhlakaza" ukuxubana nebitumen enombala ngamanzi, ngaleyo ndlela kudidiyelwe ukumanzi kwetiyela elinemibala exube abandayo.

Isitshalo sebitumen enziwe nge-emulsified siyashisa sincibilikisa isisekelo setiyela esinemibala exutshwe namakhaza, bese sihlakaza izinhlayiya zetiyela ezinombala oxutshwe kancane esixutshweni esimanzi esiqukethe i-emulsifier ngomshini ukuze senze uketshezi lwamashidi anombala obandayo axutshwe nebitumen. Udaka lwempahla yebitumen ene-emulsified esetshenziselwa isakhiwo se-slab ballastless track sisebenzisa isitshalo sebitumen se-cationic emulsion. Ukuze kudidiyelwe ukunwebeka, ukuqina kanye nekhwalithi yodaka lwemishini yebitumen e-emulsified, ama-polymers avame ukusetshenziselwa ukuguqula itiyela.
