Isembozo esingangeni manzi se-bitumen eguquliwe nge-polymer
Ukugqoka okungangenwa yi-bitumen eguquliwe nge-polymer kuyingubo engangenwa yi-emulsion yamanzi noma i-solvent elungiselelwe ngokusebenzisa i-bitumen njengezinto eziyisisekelo futhi eguquliwe ngama-polymers aqukethe ama-molecule amaningi.
Kubhekiselwa embozweni ongangeni manzi osekelwe emanzini noma e-solvent owenziwe nge-asphalt njengento eyisisekelo futhi oguqulwe ngama-polymers aphezulu okwenziwa, ikakhulukazi ama-raber ahlukahlukene. Lolu hlobo lokumbozwa lungabizwa nangokuthi i-asphalt engangeni manzi eguqulwe irabha, ethuthukise kakhulu ukuguquguquka, ukumelana nokuqhekeka, amandla okuthamba, ukumelana nokushisa okuphezulu nokuphansi, kanye nokuphila kwenkonzo uma kuqhathaniswa ne-asphalt-based coatings.
Izinhlobo eziyinhloko yilezi
Isembozo esingangeni manzi se-asphalt esilungisiwe kabusha,
Isembozo esingangeni manzi se-asphalt yerabha ye-neoprene yohlobo lwe-emulsion yamanzi,
Isembozo esingangeni manzi se-asphalt eguquliwe yerabha ye-SBS, njll.
Ifanelekela amaphrojekthi okuvikela amanzi njengophahla, umhlabathi, izindlu zangaphansi zekhonkrithi kanye nezindlu zangasese ezinamazinga angangeni manzi e-II, III kanye ne-IV.
Isembozo esingangeni manzi se-asphalt esilungisiwe kabusha
Isembozo esingangeni manzi se-bitumen esiguquliwe ngerabha singahlukaniswa ngohlobo lwesinyibilikisi kanye nohlobo lwe-emulsion yamanzi ngokuya nge-medium ehlukile yokuhlakazeka.
Ukufakwa kwe-asphalt engangeni manzi okusekelwe ku-solvent okusekelwe ku-solvent okwenziwe nge-asphalt ephinde yasetshenziswa njenge-modifier, uphethiloli njenge-solvent, okunezela ezinye izigcwalisi ezifana ne-talc, i-calcium carbonate, njll., ngemva kokushisa nokuxuba. Inzuzo ukuthi ithuthukisa ukuguquguquka nokuqina kokufakwa kwe-asphalt engangeni manzi, futhi inezinhlobonhlobo zezinto zokusetshenziswa, izindleko eziphansi, kanye nokukhiqizwa okulula. Kodwa-ke, ngenxa yokusetshenziswa kukaphethiloli njenge-solvent, kufanele kuqashelwe ukuvimbela umlilo kanye nokungenisa umoya ngesikhathi sokwakha, futhi kudingeka imidwebo eminingi ukuze kwakhiwe ifilimu Eqinile engcono. Ifanelekela uphahla lwezakhiwo zezimboni nezomphakathi olungangeni manzi, olungangeni manzi, olungangeni manzi, kanye nokugcinwa kophahla oludala.
Ukufakwa kwamanzi kwe-bitumen engangeni manzi okufana nerabha eguquliwe yohlobo lwe-emulsion yakhiwe yi-latex evuselelwe ye-anionic kanye ne-anionic bitumen latex. Izinhlayiya ze-raber evuselelwe kanye ne-petroleum bitumen zihlakazeka emanzini futhi zakhiwe yisenzo se-anionic surfactants. . Ukufakwa kwamanzi kusetshenziswa amanzi njengesihlanzi, futhi kunezinzuzo zokungangenwa ubuthi, ukunganuki, nokungashi. Kungafakwa emakhazeni ekamelweni lokushisa futhi kungasetshenziswa endaweni emanzi kancane ngaphandle kwamanzi amile. Ukufakwa ngokuvamile kufakwe indwangu yefayibha yengilazi noma i-fibre eqinisiwe yokwenziwa ukuze kwakhiwe ungqimba olungangeni manzi, futhi i-caulking paste iyengezwa ngesikhathi sokwakha ukuze kufezwe umphumela ongcono wokungangeni manzi. Ukufakwa kwamanzi kufanelekela ukuvalwa kwamanzi kophahla lwesisekelo sekhonkrithi lwezakhiwo zezimboni nezomphakathi; ukuvalwa kwamanzi kophahla lokufaka ukushisa nge-asphalt perlite njengokufakwa kokushisa; ukuvalwa komswakama kwezakhiwo zekhonkrithi ezingaphansi komhlaba, ukulungiswa kophahla lwe-linoleum oludala, kanye nokugcinwa kophahla oluqinile olungangeni manzi.
Isembozo samanzi se-emulsion se-neoprene rubber asphalt
Isembozo esingangeni manzi se-asphalt yerabha ye-chloroprene enamanzi sakhiwe yi-cationic chloroprene latex kanye ne-cationic asphalt emulsion. Senziwe ngerabha ye-chloroprene kanye nezinhlayiya ze-asphalt ye-petroleum. Sakhiwa ngokuhlakazeka emanzini ngosizo lwe-cationic surfactants. Uhlobo lwesembozo esingangeni manzi sohlobo lwe-emulsion yamanzi.
Ngenxa yokuguqulwa kwe-neoprene, upende unezinzuzo ezimbili ze-neoprene ne-asphalt. Unokumelana okuhle nesimo sezulu kanye nokumelana nokugqwala, ukuguquguquka okuphezulu, ukunwebeka nokunamathela, kanye nokuzivumelanisa okunamandla nokuguquguquka kwesendlalelo sesisekelo. , Ifilimu yopende yokushisa okuphansi ayiqhekeki, izinga lokushisa eliphezulu aligelezi, ifilimu yopende iqinile futhi iphelele, futhi ukumelana kwamanzi kuhle. Ngaphezu kwalokho, upende we-asphalt werabha we-neoprene werabha usebenzisa amanzi njengesinyibilikisi, esingagcini nje ngokuba nezindleko eziphansi, kodwa futhi sinezinzuzo zokungcola okungenabuthi, okungashi, kanye nokungcoliswa kwemvelo ngesikhathi sokwakha.
Ifaneleka ekuvimbeni amanzi ophahleni, ekuvimbeni amanzi odongeni kanye nasekuvimbeni amanzi phansi kwezakhiwo zezimboni nezomphakathi, ekuvimbeni amanzi emapayipini angaphansi komhlaba kanye nemishini, futhi ifaneleka nokulungisa ukuvuza kwezindlu ezindala.
Isembozo esingangeni manzi se-asphalt eguquliwe yerabha ye-SBS
Isembozo esingangeni manzi se-asphalt esiguquliwe se-SBS uhlobo lwesembozo esingangeni manzi se-asphalt elastic esakhiwe yi-asphalt, i-raber SBS resin (i-styrene-butadiene-styrene block copolymer) kanye nama-surfactants nezinye izinto ze-polymer. Izinzuzo zalesi sembozo ukuguquguquka okuhle kokushisa okuphansi, ukumelana okunamandla kokuqhekeka, ukusebenza okuhle kakhulu kokubopha, kanye nokumelana okuhle kokuguga. Ihlanganiswe nendwangu yefayibha yengilazi kanye nezinye izidumbu eziqinisiwe. Isebenza kahle kakhulu ekungangeni manzi futhi ingasetshenziswa emisebenzini yokwakha ebandayo. Isembozo esingangeni manzi esifanelekile esiphakathi nendawo.
Ifanele ukwakhiwa kwezisekelo eziyinkimbinkimbi ezingangeni manzi futhi ezingangeni umswakama, njengezindlu zangasese, amagumbi angaphansi komhlaba, amakhishi, amachibi okubhukuda, njll., ifaneleka kakhulu kumaphrojekthi okuvikela amanzi ezindaweni ezibandayo.
