Ibhitumene ye-emulsion yi-emulsion entsha eyenziwe ngumatshini we-asphalt kunye ne-emulsifier isisombululo samanzi.
Ibhitumene ye-Emulsion ihlelwa ngokweendlela ezahlukeneyo ze-particle ye-bitumen emulsifier esetyenziswayo: i-cationic emulsion bitumen, i-anionic emulsion bitumen kunye ne-nonionic emulsion bitumen.
Ngaphezulu kwe-95% yolwakhiwo lwendlela isebenzisa ibhitumene ye-cationic emulsion. Kutheni ibhitumene ye-cationic emulsion ineenzuzo ezinjalo?
1. Ukukhethwa kwamanzi kubanzi. Ibhitumene, amanzi kunye nebhitumene emulsifier zezona zixhobo ziphambili kwi-emulsion bitumen. Ibhitumene ye-anionic emulsified kufuneka ilungiswe ngamanzi athambileyo kwaye ayinakuxutywa ngamanzi anzima. Kwibhitumen ye-cationic emulsion, unokukhetha i-emulsion bitumen yamanzi anzima. Ungasebenzisa amanzi anzima ukulungiselela isisombululo se-emulsifier yamanzi, okanye ungayihlambulula ngokuthe ngqo.
2. Imveliso elula kunye nokuzinza okulungileyo. Ukuzinza kwee-anions kubi kwaye i-admixtures kufuneka yongezwe ukuqinisekisa ukuzinza kwemveliso egqityiweyo. Kwiimeko ezininzi, i-bitumen ye-cationic emulsion inokuvelisa i-emulsion bitument ezinzileyo ngaphandle kokufaka ezinye izongezo.
3. Kwi-bitumen ye-cationic emulsion, kukho iindlela ezininzi zokulungelelanisa isantya se-demulsification kwaye iindleko ziphantsi.
4. I-asphalt yeCationic emulsified isenokwakhiwa njengesiqhelo kumaxesha okufuma okanye amaqondo obushushu aphantsi (ngaphezu kwe-5℃).
5. Ukubambelela kakuhle kwilitye. Amasuntswana ebhitumene e-cationic emulsion athwala iindleko ze-cationic. Xa udibana nelitye, iinqununu ze-asphalt zikhangiswa ngokukhawuleza kumphezulu welitye ngenxa yokukhanga kweepropati ezichaseneyo. Isetyenziswa kwi-micro surfacing kunye nolwakhiwo lwetywina oluludaka.
6. I-viscosity ye-bitumen ye-cationic emulsion ingcono kune-bitumen ye-anionic emulsion. Xa ukupenda, i-bitumen ye-cationic emulsion inzima kakhulu, ngoko unokukhetha ukuyitshiza. Ngokuchasene noko, i-anionic emulsion bitumen kulula ukuyipeyinta. Ingasetyenziswa njenge-oyile yomaleko egqobhozayo kunye ne-oyile encangathi yomaleko kwisakhiwo sokungangeni kwamanzi kunye nokuhamba kwendlela.
7. Ibhitumene ye-cationic emulsion ivula izithuthi ngokukhawuleza.
