Emulsion bitumen waa emulsion cusub oo lagu sameeyay fal farsamo ee asphalt iyo emulsifier xal aqueous.
Emulsion bitumen waxaa loo kala saaraa iyadoo loo eegayo sifooyinka qayb ee kala duwan ee emulsifier-ka la isticmaalo: cationic emulsion bitumen, bitumen emulsion anionic iyo bitumen emulsion nonionic.
In ka badan 95% ee dhismaha waddooyinku waxay isticmaalaan bitumen-ka emulsion-ka. Waa maxay sababta cationic emulsion bitumen ay leedahay faa'iidooyin noocaas ah?
1. Xulashada biyaha ayaa aad u ballaaran. Bitumen, biyaha iyo emulsifier-ga bitumen ayaa ah agabka ugu muhiimsan ee bitumen-ka emulsion-ka. Anionic emulsified bitumen waa in lagu diyaariyaa biyo jilicsan oo laguma qasi karo biyo adag. Wixii qaniinyada emulsion cationic, waxaad dooran kartaa emulsion bitumen biyo adag. Waxaad isticmaali kartaa biyo adag si aad u diyaariso emulsifier xal aqueous ah, ama si toos ah ayaad u milo kartaa.
2. Wax soo saar fudud iyo xasillooni wanaagsan. Xasiloonida anions waa mid liidata waxaana loo baahan yahay in lagu daro isku-darka si loo hubiyo xasiloonida alaabta la dhammeeyey. Xaalado badan, qaniinyada emulsion cationic waxay soo saari kartaa qaniinyada emulsion deggan iyada oo aan lagu darin waxyaabo kale.
3. Bitumen cationic emulsion, waxaa jira siyaabo badan oo lagu hagaajin karo xawaaraha demulsification qiimuhuna waa yar yahay.
4. Asphalt-ka Emulsified Cationic wali waxa loo dhisi karaa sidii caadiga ahayd xilliyada qoyan ama kulaylka hooseeya (ka sarreeya 5 ℃).
5. Ku dhajinta wanaagsan ee dhagaxa. Qaybaha bitumen emulsion cationic waxay wataan kharashyo cationic ah. Markaad la xiriirto dhagaxa, qaybaha asphalt ayaa si dhakhso ah loogu dhajiyaa dusha sare ee dhagaxa sababtoo ah soo jiidashada hantida ka soo horjeeda. Loo isticmaalo dhismaha dusha sare ee yar yar iyo dhismaha shaambada slurry.
6. Viscosity of cationic emulsion bitumen waa ka fiican yahay bitumen emulsion anionic. Markaad rinjiyeynayso, bitumen cationic emulsion waa mid aad u adag, markaa waxaad dooran kartaa inaad ku buufiso. Taas bedelkeeda, bitumen emulsion anionic waa sahlan tahay in la rinjiyeeyo. Waxaa loo isticmaali karaa sida saliid lakabka geliya iyo saliidda lakabka dhegdheg ee dhismaha biyaha-ilaalinta iyo laamiyada waddooyinka.
7. Bitumen Cationic emulsion si dhakhso ah ayey ugu furaa taraafikada.
