I-emulsion bitumen iyi-emulsion entsha eyakhiwe isenzo somshini se-asphalt ne-emulsifier isisombululo samanzi.
Ibitumen ye-emulsion ihlukaniswa ngokwezakhiwo zezinhlayiya ezihlukene ze-bitumen emulsifier esetshenzisiwe: i-cationic emulsion bitumen, i-anionic emulsion bitumen ne-nonionic emulsion bitumen.
Ngaphezu kwe-95% yokwakhiwa komgwaqo kusebenzisa i-cationic emulsion bitumen. Kungani itiyela le-cationic emulsion linezinzuzo ezinjalo?
1. Ukukhethwa kwamanzi kubanzi uma kuqhathaniswa. Ibitumeni, amanzi kanye ne-bitumen emulsifier yizinto eziyinhloko zebitumen ye-emulsion. Ibitumen ye-anionic emulsified kufanele ilungiswe ngamanzi athambile futhi ayikwazi ukuhlanjululwa ngamanzi aqinile. Ukuze uthole i-bitumen ye-cationic emulsion, ungakhetha i-emulsion bitumen yamanzi aqinile. Ungasebenzisa amanzi aqinile ukulungisa isixazululo samanzi se-emulsifier, noma ungasihlanza ngokuqondile.
2. Ukukhiqizwa okulula nokuzinza okuhle. Ukuzinza kwama-anions akulungile futhi izingxube zidinga ukungezwa ukuze kuqinisekiswe ukuzinza komkhiqizo ophelile. Ezimweni eziningi, i-cationic emulsion bitumen ingakhiqiza i-emulsion bitument ezinzile ngaphandle kokwengeza ezinye izithasiselo.
3. Ngebhitumen ye-cationic emulsion, kunezindlela eziningi zokulungisa isivinini se-demulsification futhi izindleko ziphansi.
4. I-Cationic emulsified asphalt isengakhiwa njengenjwayelo ezinkathini eziswakeme noma ezinezinga lokushisa eliphansi (ngaphezu kuka-5℃).
5. Ukunamathela okuhle etsheni. Izinhlayiya zebitumen ze-cationic emulsion zithwala amashaji e-cationic. Lapho uthintana netshe, izinhlayiya ze-asphalt zikhangiswa ngokushesha ebusweni betshe ngenxa yokukhangwa kwezakhiwo eziphambene. Isetshenziswa ekwakhiweni kwe-microsurfacing kanye nokwakhiwa kwe-slurry seal.
6. I-viscosity yebitumen ye-cationic emulsion ingcono kunebitumen ye-anionic emulsion. Lapho ukudweba, i-bitumen ye-cationic emulsion inzima kakhulu, ngakho-ke ungakhetha ukuyifafaza. Ngokuphambene nalokho, i-anionic emulsion bitumen kulula ukuyipenda. Ingasetshenziswa njengamafutha ongqimba angena ngaphakathi kanye nowoyela ongqimba onamathelayo ekwakheni ukuvikela amanzi kanye nokugandaywa komgwaqo.
7. Ibitumen ye-iconic emulsion ivula ithrafikhi ngokushesha.
