I-Hydroxyethyl cellulose (HEC) iyisithako esibalulekile esisebenza ngezindlela eziningi esidlala indima ebalulekile ekufutheni izembozo ezingangeni manzi ze-asphalt yerabha ezisheshayo. Imisebenzi yayo eyinhloko ihlanganisa ukuqina, ukugcinwa kwamanzi, ukulungiswa kwe-rheology kanye nokuqina kokumiswa.
1. Umphumela wokuqina
Njenge-thickener engeyona i-ionic, i-hydroxyethyl cellulose ingakhulisa kakhulu i-viscosity yezingubo ezingangeni manzi ze-asphalt yerabha ezifafazwa ngokushesha. Ngenxa yezimpawu zayo ezihlukile ze-viscosity ephezulu, i-HEC ingakhulisa ngempumelelo i-viscosity yesakhiwo sengubo ukuze ikwazi ukugcina ukuvumelana okufanele ngesikhathi senqubo yokwakha. Lo msebenzi ubaluleke kakhulu ekwakhiweni kokufutha, ngoba i-viscosity efanele isiza upende ukuthi usatshalaliswe ngokulinganayo, unciphise ukugoba, futhi uqinisekise ukuvumelana kobukhulu bengubo, ngaleyo ndlela kufezwe imiphumela emihle kakhulu yokuvimbela amanzi.
2. Umphumela wokugcina amanzi
I-HEC inokugcinwa kwamanzi okuhle kakhulu, okubaluleke kakhulu ekumbozweni okusekelwe emanzini. Ezimbozweni ezingangeni manzi zerabha ezifakwe i-asphalt ngerabha ezifakwe i-spray-coated quick-setting, i-HEC inganciphisa izinga lokuhwamuka kwamanzi embozweni ngokugcina umswakama. Lesi sici asisizi nje kuphela ukugcina isimo somswakama sembozo ngesikhathi sokwakhiwa futhi sivimbele ukwakheka ukuthi kome ngenxa yokulahleka kwamanzi okusheshayo, kodwa futhi sikhuthaza ukungena kwembozo embozweni futhi sithuthukise ukunamathela embozweni, ngaleyo ndlela kuthuthukiswe ukusebenza okuphelele kwengqimba yokuvimbela amanzi.
3. Ukulungiswa kwe-Rheology
I-Rheology ibhekisela ezicini zokugeleza kopende ngaphansi kwesenzo samandla angaphandle. I-HEC isebenza njengesiguquli se-rheology ekufutheni izembozo ezingangeni manzi ze-asphalt yerabha ezisheshayo, ezingalungisa ukuziphatha kwe-rheological kwesembozo ukuze ibonise i-viscosity ephezulu ngamazinga aphansi okucheba kanye ne-viscosity ephezulu ngamazinga aphezulu okucheba. I-viscosity ephansi. Lokhu kuziphatha kwe-rheological okuncishisiwe kusiza ipompo yopende kanye ne-spray emishinini yokufafaza futhi kubuyele ngokushesha ku-viscosity ephezulu ngemva kokufaka, ngaleyo ndlela kuncishiswe ukuphuma kopende futhi kuqinisekiswe ukushelela kanye nokufana kwesembozo.
4. Umphumela wokumiswa kanye nokuqina
Ekufutheni i-asphalt yerabha efakwa ngokushesha, izinhlayiya eziqinile ezahlukahlukene, njengezinhlayiya zerabha, ama-filler, njll., zingase zihlale embozweni ngenxa yokwehluka kobuningi. Ngokwakha isakhiwo senethiwekhi esinokuqina okuphezulu, i-HEC ingamisa ngempumelelo lezi zinhlayiya eziqinile futhi izivimbele ukuthi zihlale ngesikhathi sokugcina nokwakha. Lokhu kuzinzisa ukumiswa kusiza ukugcina ukufana kopende futhi kuqinisekisa ukuthi upende ofuthiwe unokwakheka okufanayo, ngaleyo ndlela wakhe ungqimba olungangeni manzi olufanayo ngemva kokupholisa nokuthuthukisa umphumela wokuvimbela amanzi.
5. Ukuthuthukiswa kokusebenza kokwakha
Imisebenzi eminingi ye-HEC ingathuthukisa kakhulu ukusebenza kokwakhiwa kwezembozo ezingangeni manzi ze-asphalt yerabha ezifafazwa ngokushesha. Okokuqala, umphumela wokujiya we-HEC kanye nomsebenzi wokulungisa i-rheology kwenza upende usebenze kahle ngesikhathi sokwakhiwa kwe-spray, kube lula ukuwusebenzisa futhi wakhe isembozo esibushelelezi. Okwesibili, ukugcinwa kwamanzi kwawo kusiza ekuthuthukiseni ukunamathela kopende ku-substrate futhi kunciphisa amaphutha okumboza abangelwa ukuqhekeka okomile. Ngaphezu kwalokho, umphumela wokuzinza kokumiswa kwe-HEC ungagcina ukuhambisana kwezithako zokumboza, ngaleyo ndlela kuqinisekiswe izakhiwo zomzimba ezizinzile zesembozo ngemva kokwakhiwa futhi kwandise impilo yenkonzo yesembozo.
Ukusetshenziswa kwe-hydroxyethyl cellulose ekufakeni izembozo ezingangeni manzi ze-asphalt yerabha ezisheshayo kudlala indima ebalulekile ezicini eziningi. Akugcini nje ngokwandisa i-viscosity yopende futhi kuthuthukise ukugcinwa kwamanzi, kodwa futhi kulungisa izakhiwo ze-rheological zopende, kuzinzise izinhlayiya eziqinile kupende, futhi kuthuthukise ukusebenza kokwakhiwa. Le miphumela iqinisekisa ukusebenza nokuqina kwesembozo ezisetshenziswayo, okwenza i-hydroxyethyl cellulose ibe yisithasiselo esibalulekile ekufakeni izembozo ezingangeni manzi ze-asphalt yerabha ezisheshayo. Ngokukhetha nokusebenzisa i-HEC ngendlela efanele, ukusebenza okuphelele kwezembozo ezingangeni manzi kungathuthukiswa kakhulu, ngaleyo ndlela kuhlinzekwe ngesisombululo esithembeke kakhulu sokuvimbela amanzi esakhiweni.
