Umkhiqizi we-calcium formateI-Aojin Chemical yabelana nawe ngokusetshenziswa kwe-calcium formate embonini kasimende wokwakha. I-calcium formate ethengiswa yi-Aojin Chemical inokuqukethwe okuphezulu kwama-98% futhi ipakishwa ku-25kg/isikhwama.
Umkhiqizi we-calcium formate i-Aojin Chemical yabelana ngokusebenza kwayo embonini kasimende wokwakha. I-Aojin Chemical ithengisa i-calcium fomati enokuqukethwe okuphezulu okungu-98%, okupakishwe ezikhwameni ezingama-25kg.
I-Calcium formate (Ca(HCOO)₂), i-ejenti yamandla okuqala ephilayo esebenza kahle kakhulu, isetshenziswa ekukhiqizeni imikhiqizo kakhonkolo nosimende ngenxa yamakhemikhali ayo ahlukile. Imisebenzi yayo eyinhloko kanye nezicelo yilena elandelayo:
1. Amandla Akuqala Nokusetha Ukusheshisa
I-calcium formate isheshisa kakhulu ukugeleza kukasimende, ikakhulukazi i-hydration ye-tricalcium silicate (C₃S) ne-tricalcium aluminate (C₃A). Lokhu kusheshisa ukwakheka nokubekwa kwemikhiqizo ye-hydration (njenge-ettringite ne-calcium hydroxide), ngaleyo ndlela kuthuthukiswe amandla okuqala ezinto ezisekelwe kusimende (amandla angakhuphuka ngo-20% -50% phakathi kwezinsuku ezingu-1-7). Le ndawo iyenza ifaneleke ngokukhethekile ukwakhiwa kwezinga lokushisa eliphansi (njengokuthela ebusika) noma amaphrojekthi okulungisa izimo eziphuthumayo, ukunciphisa isikhathi sokuphulukisa nokuqinisekisa ukuthi ukhonkolo uqina ngokujwayelekile ezindaweni ezisezingeni eliphansi, ngaleyo ndlela kuvinjwe umonakalo owenziwe yiqhwa.
2. Ukusebenza Okuthuthukisiwe Kokhonkolo Nokuqina
Ekunamathisele usimende, i-calcium fomati inciphisa ukopha nokuhlukaniswa, ithuthukise ukufana kwekhonkrithi kanye nokuminyana. Ngaphezu kwalokho, imikhiqizo yayo ye-hydration igcwalisa izimbotshana zikasimende, inciphisa i-porosity, ithuthukisa ngokungaqondile ukungakwazi ukuqina kukakhonkolo, ukumelana nesithwathwa, nokumelana nokugqwala, ngaleyo ndlela andise impilo yesevisi yemikhiqizo kasimende.
3. Ifanele izinhlobonhlobo zezicelo zomkhiqizo usimende
Emkhiqizweni wengxenye ye-precast, njengamaphaneli we-precast kanye nezinqwaba zamapayipi, i-calcium fomate isheshisa ukuthengiswa kwesikhunta, ifinyeze isikhathi sokudiliza, futhi ithuthukise ukusebenza kahle kokukhiqiza.
I-Shotcrete: Isetshenziswa ekusebenzeni kokufafaza emhubheni, ezimayini, nakwamanye amaphrojekthi, iyasetha ngokushesha futhi ibe lukhuni, yehlise ukulahleka okuphindayo futhi ithuthukise ukusebenza kahle kokwakhiwa.
Udaka nezinto zokwakha: Ithuthukisa ukugcinwa kwamanzi kanye namandla okuqala odaka, iqinisekisa inqubekelaphambili esheshayo enqubweni yokwakhiwa kwamatshe kanye neyophahla.
4. Izinzuzo Zendawo Ezungezile Nokuhambisana
I-Calcium Formate Priceayinabo ubuthi futhi ayicunuli, futhi ihambisana nosimende, izinto ezinciphisa amanzi, umlotha wempukane, nezinye izixube. Ayibangeli izinkinga ezifana nokusabela kwe-alkali-aggregate kukhonkolo, ukuhlangabezana nezidingo zokuthuthukiswa kwezinto zokwakha eziluhlaza. Qaphela: Umthamo we-calcium formate kufanele ulawulwe ngokuqinile (ngokujwayelekile u-1% -3% wesisindo sikasimende). Ukwengeza ngokweqile kungase kubambezele ukukhula kwamandla kamuva kukakhonkolo futhi kubangele nokuqhekeka kokuncipha. Ukulungiswa kufanele kwenziwe ngokusekelwe ezintweni ezifana nendawo yephrojekthi kanye nohlobo lukasimende.
