Izinhlelo zokusebenza
➢ Ukuzivumelanisa nezimo ezinhle kuzo zonke izinhlobo zikasimende, ukwenza ngcono ukusebenza kukasimende, osetshenziswa kakhulu emigwaqweni, kojantshi, amabhuloho, amahubhe, iziteshi zikagesi, ama-DAMS, izakhiwo eziphakeme kanye namanye amaphrojekthi.
1. Ukuhlanganisa umthamo ku-0.5% -1.0%,0.75% umthamo wokuxuba uyalulekwa.
2. Lungiselela izixazululo njengoba kudingeka.
3. Ukusetshenziswa okuqondile kwe-powder agent kuvunyelwe, okunye ukungezwa kwe-ejenti kulandelwa umswakama wamanzi (isilinganiso samanzi-simende: 60%).
Imisebenzi Esemqoka
➢ I-SNF-A inganikeza udaka isivinini esisheshayo sokwenziwa kwepulasitiki, umphumela wokwenza uketshezi oluphezulu, umphumela wokungenisa umoya ophansi.
➢ I-SNF-A isebenzisana kahle nezinhlobo ezehlukene zikasimende noma izibophezelo zegypsum, ezinye izithasiselo ezifana ne-ejenti yokukhipha amagwebu, i-thickener, iretarder, i-ejenti enwebekayo, i-accelerator njll.
➢ I-SNF-A ifanele i-tile grout, izinhlanganisela ezizilinganisayo, ukhonkolo onobuso obufanele kanye nesiqinisi saphansi esinemibala.
Ukusebenza Komkhiqizo
➢ I-SNF ingasetshenziswa njenge-ejenti yokumanzisa udaka lwengxube eyomile ukuze kutholakale ukusebenza kahle.
☑ Isitoreji nokulethwa
Kufanele igcinwe futhi ilethwe ngaphansi kwezimo ezomile nezihlanzekile ngendlela yayo yephakheji yasekuqaleni futhi kude nokushisa.Ngemva kokuba iphakheji selivuliwe ukuze likhiqizwe, ukuvala kabusha okuqinile kufanele kuthathwe ukuze kugwenywe ukungena komswakama.
☑ Impilo yeshelufu
Impilo yeshelufu izinyanga eziyi-10. Yisebenzise ngokushesha ngangokunokwenzeka ngaphansi kokushisa okuphezulu nomswakama, ukuze ungakhulisi amathuba okwenza i-caking.
☑ Ukuphepha komkhiqizo
I-superplasticizer esekelwe ku-Naphthalene i-SNF-A ayikona okokusebenza okuyingozi.Ulwazi olwengeziwe mayelana nezici zokuphepha lunikezwe ku-Material Safety Data Sheet.
