I-Setting-Accelerator—I-Calcium Formate

I-calcium formate ingasebenza njengesisheshisi sokusetha kukhonkolo. Nansi indlela esebenza ngayo:

Ukusetha Indlela Yokusheshisa:

1. Inqubo Yokumanzisa: Uma i-calcium formate ingezwa ezingxubeni zekhonkrithi, iyancibilika emanzini bese ikhipha ama-ion e-calcium (Ca^2+) nama-ion e-formate (HCOO^-).
2. Ukukhuthazwa Kokwakheka kwe-CSH: Ama-ion e-calcium (Ca^2+) akhishwa ku-calcium formate asabela nama-silicates esimendeni, okusheshisa ukwakheka kwejeli ye-calcium silicate hydrate (CSH). Le jeli ye-CSH iyisihlanganisi esiyinhloko kukhonkrithi, esinomthwalo wemfanelo wamandla nokuqina kwayo.
3. Isikhathi Sokusetha Esisheshayo: Ukwakheka okusheshayo kwejeli ye-CSH kuphumela esikhathini sokusetha esisheshayo sengxube yekhonkrithi. Lokhu kuvumela ukuqeda okusheshayo nokususwa kwamafomu kusenesikhathi, okusheshisa inqubo yokwakha iyonke.

Izinzuzo Zokusebenzisa iCalcium Formate Njenge-Setting Accelerator:

1. Amandla Athuthukisiwe Asekuqaleni: Amandla okuqala ekhonkrithi ayathuthukiswa ngenxa yenqubo yokumanzisa esheshiswayo esizwa yi-calcium formate. Lokhu kungaba wusizo ikakhulukazi ezimweni zezulu ezibandayo lapho kubhekwa khona izikhathi zokubeka ezisheshayo.
2. Isikhathi Sokwakha Esincishisiwe: Ngokusheshisa isikhathi sokusetha ukhonkolo, i-calcium formate isiza ukunciphisa isikhathi sokwakha futhi ivumela ukuqedwa kwephrojekthi ngokushesha.
3. Ukusebenza Okuthuthukisiwe: I-calcium formate ingathuthukisa nokusebenza kahle kwekhonkrithi, okwenza kube lula ukuyiphatha nokuyibeka, ikakhulukazi ezimweni lapho kudingeka khona ukusetha okusheshayo.

Isicelo kuKhonkrithi:

• I-calcium formate ivame ukungezwa ezingxubeni zekhonkrithi ngesilinganiso esisukela ku-0.1% kuya ku-2% ngesisindo sikasimende, kuye ngesikhathi sokubeka esifiselekayo kanye nezidingo zokusebenza.
• Ivame ukusetshenziswa ekukhiqizweni kokhonkolo okwenziwe kusengaphambili, ekusetshenzisweni kwe-shotcrete, kanye namaphrojekthi okwakha lapho kudingeka khona ukusetha okusheshayo.

Izinto okufanele uzicabangele:

• Nakuba i-calcium formate ingasheshisa isikhathi sokusetha ukhonkolo, kubalulekile ukucabangela ngokucophelela amazinga omthamo kanye nokuhambisana nezinye izingxube ukuze ugweme imiphumela emibi ezakhiweni zokhonkolo.
• Izindlela zokulawula ikhwalithi kufanele zisetshenziswe ukuqinisekisa ukuthi ukhonkolo osheshisiwe ugcina amandla, ukuqina, kanye nezici zokusebenza ezifiselekayo.

I-calcium formate isebenza njengesisheshisi esisebenzayo kukhonkolo, ikhuthaza ukumuncwa okusheshayo kanye nokuthuthukiswa kwamandla okuqala. Ukusetshenziswa kwayo kungasiza ekusheshiseni amashejuli okwakha futhi kuthuthukise ukusebenza kahle, ikakhulukazi ezimweni zezulu ezibandayo noma amaphrojekthi athinta isikhathi. Kodwa-ke, ukucabangela isilinganiso esifanele kanye nokuhambisana kubalulekile ekufezeni izakhiwo zekhonkolo ezifiselekayo ngenkathi kusetshenziswa i-calcium formate njengesisheshisi.
