I-Setting-Accelerator—I-Calcium Formate

I-calcium Formate ingasebenza njenge-accelerator yokusetha kukhonkolo. Nansi indlela esebenza ngayo:

Ukusetha Indlela Yokusheshisa:

1. I-Hydration Process: Uma i-calcium formate yengezwa ezixubeni zekhonkrithi, incibilika emanzini futhi ikhiphe i-calcium ion (Ca^2+) kanye ne-formate ions (HCOO^-).
2. Ukukhuthazwa Kokwakhiwa Kwe-CSH: I-calcium ions (Ca^2+) ekhishwe ku-calcium formate isabela nama-silicates kusimende, isheshisa ukwakheka kwejeli ye-calcium silicate hydrate (CSH). Le jeli ye-CSH iyisibophezelo esiyinhloko kukhonkolo, esibophezelekile ngamandla ayo kanye nokuqina.
3. Isikhathi Sokusetha Esisheshayo: Ukwakheka okusheshisiwe kwejeli ye-CSH kubangela isikhathi sokusetha esisheshayo sengxube kakhonkolo. Lokhu kuvumela ukuqedwa ngokushesha kanye nokususwa kwangaphambi kwesikhathi kwe-formwork, kusheshiswe inqubo yonke yokwakha.

Izinzuzo zokusebenzisa i-Calcium Formate njengeSetting Accelerator:

1. Amandla Angaphambili Athuthukisiwe: Amandla okuqala kakhonkolo ayathuthukiswa ngenxa yenqubo esheshiswayo yokugeleza kwamanzi eqhutshwa i-calcium formate. Lokhu kungaba yinzuzo ikakhulukazi ezimweni zezulu ezibandayo lapho izikhathi zokusetha ezihamba kancane zibonwa.
2. Isikhathi Esincishisiwe Sokwakha: Ngokusheshisa isikhathi sokumisa ukhonkolo, i-calcium formate isiza ukunciphisa isikhathi sokwakha futhi ivumela ukuqedwa kwephrojekthi ngokushesha.
3. Ukusebenza Okuthuthukisiwe: Ifomethi ye-calcium nayo ingathuthukisa ukusebenza kukakhonkolo, ikwenze kube lula ukuphatha nokubeka, ikakhulukazi ezimeni lapho kudingeka khona ukusetha okusheshayo.

Isicelo Ngokhonkolo:

• I-calcium Formate ivamise ukungezwa ezixubeni zikakhonkolo ngethamo elisukela ku-0.1% ukuya ku-2% ngesisindo sikasimende, kuye ngesikhathi esifiswayo sokusetha kanye nezidingo zokusebenza.
• Ivamise ukusetshenziswa ekukhiqizeni ukhonkolo we-precast, izicelo ze-shotcrete, namaphrojekthi wokwakha lapho ukusetha okusheshayo kuyadingeka.

Okucatshangwayo:

• Nakuba i-calcium formate ingasheshisa isikhathi sokusetha sikakhonkolo, kubalulekile ukucabangela ngokucophelela izilinganiso zomthamo kanye nokuhambisana nezinye izingxube ukuze ugweme imiphumela emibi ezimpahleni ezikhonkolo.
• Izinyathelo zokulawula ikhwalithi kufanele zisetshenziswe ukuze kuqinisekiswe ukuthi ukhonkolo osheshayo ugcina amandla afunekayo, ukuqina, nezici zokusebenza.

I-calcium Formate isebenza njengesisheshisi esisebenzayo sokusheshisa kukhonkolo, sikhuthaza ukugeleza kwamanzi ngokushesha kanye nokuthuthukiswa kwamandla okuqala. Ukusetshenziswa kwayo kungasiza ukusheshisa amashejuli wokwakha futhi kuthuthukise ukusebenza, ikakhulukazi ezimweni zezulu ezibandayo noma amaphrojekthi azwela isikhathi. Kodwa-ke, umthamo ofanele nokucatshangelwa kokuhambisana kubalulekile ekuzuzeni izakhiwo ezifiselekayo zekhonkrithi ngenkathi usebenzisa i-calcium formate njengesisheshisi.
