Umkhiqizi we-calcium formateI-Aojin Chemical yabelana nawe ngokusetshenziswa kwe-calcium formate embonini yesimende yokwakha. I-calcium formate ethengiswa yi-Aojin Chemical inokuqukethwe okuphezulu okungu-98% futhi ipakishwe ku-25kg/isikhwama.
Umkhiqizi we-calcium formate i-Aojin Chemical wabelana ngezicelo zakhe embonini yesimende yokwakha. I-Aojin Chemical ithengisa i-calcium formate enokuqukethwe okuphezulu okungu-98%, okupakishwe ezikhwameni ezingama-25kg.
I-Calcium formate (Ca(HCOO)₂), i-ejenti enamandla okuqala e-organic esebenza kahle kakhulu, isetshenziswa ekukhiqizweni kwemikhiqizo yekhonkrithi nesamente ngenxa yezakhiwo zayo zamakhemikhali ezihlukile. Imisebenzi yayo eyinhloko kanye nezicelo zayo yile elandelayo:
1. Amandla Okuqala Nokusheshisa Kokusetha
I-calcium formate isheshisa kakhulu ukumuncwa kwesimende, ikakhulukazi ukumuncwa kwe-triccalcium silicate (C₃S) kanye ne-triccalcium aluminate (C₃A). Lokhu kusheshisa ukwakheka nokubekwa kwemikhiqizo yokumuncwa (njenge-ettringite kanye ne-calcium hydroxide), ngaleyo ndlela kuthuthukiswe amandla okuqala ezinto ezisekelwe kusimende (amandla anganda ngo-20%-50% zingakapheli izinsuku ezingu-1-7). Lesi sici siyenza ifaneleke kakhulu ekwakhiweni kwezinga lokushisa eliphansi (njengokuthululwa ebusika) noma amaphrojekthi okulungisa okuphuthumayo, kufinyezwe isikhathi sokusikwa nokuqinisekisa ukuthi ukhonkolo uqina ngokujwayelekile ezindaweni ezisezingeni lokushisa eliphansi, ngaleyo ndlela kuvinjelwe umonakalo wokuqandisa.
2. Ukusebenza Okuthuthukisiwe Nokuqina Kokhonkolo
Ku-paste yesimende, i-calcium formate inciphisa ukuphuma kwegazi kanye nokuhlukaniswa, ithuthukisa ukulingana kanye nobuningi bekhonkrithi. Ngaphezu kwalokho, imikhiqizo yayo yokumanzisa igcwalisa izikhala ze-paste yesimende, inciphisa ukubhoboka, ithuthukisa ngokungaqondile ukungakwazi ukungenwa yikhonkrithi, ukumelana nesithwathwa, kanye nokumelana nokugqwala, ngaleyo ndlela yandisa impilo yenkonzo yemikhiqizo yesimende.
3. Ifanele izinhlobo ezahlukene zezicelo zomkhiqizo wesamente
Ekukhiqizweni kwezingxenye ezilungiselelwe kusengaphambili, njengamaphaneli alungiselelwe kusengaphambili kanye namapayipi, i-calcium formate isheshisa ukujika kwesikhunta, ifinyeze isikhathi sokunciphisa, futhi ithuthukise ukusebenza kahle kokukhiqiza.
I-Shotcrete: Isetshenziswa emisebenzini yokufafaza emihubheni, ezimayini, nakwamanye amaphrojekthi, iyashesha futhi iqine, inciphise ukulahlekelwa kokubuyela emuva futhi ithuthukise ukusebenza kahle kokwakha.
Izinto zokwakha udaka kanye nokwakha: Kuthuthukisa ukugcinwa kwamanzi kanye namandla okuqala kodaka, kuqinisekisa intuthuko esheshayo ezinqubweni zokwakha nokwakha.
4. Izinzuzo Zemvelo Nokuhambisana
Intengo ye-calcium formateAyinabo ubuthi futhi ayicasuli, futhi iyahambisana nesimende, izinto ezinciphisa amanzi, umlotha wezimpukane, nezinye izinto ezixubile. Ayibangeli izinkinga ezifana nokusabela kwe-alkali-aggregate kukhonkrithi, okuhlangabezana nezidingo zokuthuthukiswa kwezinto zokwakha eziluhlaza. Qaphela: Isilinganiso se-calcium formate kumele silawulwe ngokuqinile (ngokuvamile i-1%-3% yesisindo sesimende). Ukwengeza ngokweqile kunganciphisa ukukhula kwamandla ekhonkrithi kamuva futhi kubangele ngisho nokuqhekeka. Ukulungiswa kufanele kwenziwe ngokusekelwe ezicini ezifana nendawo yephrojekthi kanye nohlobo lwesimende.
