Hauv kev tsim cov khoom siv hauv tsev, cov cement yog cov khoom siv yooj yim rau kev siv, thiab kev ua kom zoo ntawm nws cov kev ua tau zoo ib txwm yog qhov tseem ceeb ntawm kev tshawb fawb. Calcium formate, raws li cov khoom siv ntxiv, ua lub luag haujlwm tseem ceeb hauv cov cement.
1. Ceev cov cement hydration cov tshuaj tiv thaiv
Calcium formatetuaj yeem ua kom nrawm nrawm ntawm cov txheej txheem dej ntawm cov cement. Tom qab cov cement yog tov nrog dej, cov calcium ions hauv calcium formate tuaj yeem hnov mob nrog cov ntxhia hauv cov khoom xws li tricalcium silicate thiab dicalcium silicate hauv cov cement los txhawb kev tawg ntawm cov cement minerals thiab tsim cov khoom hydration. Qhov no tso cai rau cov cement kom ncav cuag lub zog siab dua hauv lub sijhawm luv dua, txo lub sijhawm ntawm cov cement, thiab txhim kho kev tsim kho.
2. Txhim kho lub zog thaum ntxov
Vim yog cov nyhuv nrawm ntawm calcium formate ntawm cov cement hydration cov tshuaj tiv thaiv, nws tuaj yeem txhim kho lub zog thaum ntxov ntawm cov cement. Hauv kev tsim cov khoom siv cement xws li cov khoom siv ua vaj tse precast thiab cov cement cib, kev txhim kho ntawm lub zog thaum ntxov tuaj yeem ua kom lub zog ntawm pwm thiab txo cov nqi tsim khoom. Nyob rau tib lub sijhawm, rau qee qhov haujlwm uas yuav tsum tau muab tso rau hauv kev siv sai sai, xws li kev kho txoj kev thiab kev tsim kho tshav dav hlau, kev ntxiv cov calcium formate tuaj yeem ua kom ntseeg tau tias qhov project muaj lub zog txaus hauv lub sijhawm luv kom tau raws li kev siv.
3. Txhim kho qhov Frost tsis kam ntawm cov cement
Hauv cov cheeb tsam txias, cov khoom siv cement ntsib qhov kev sim ntawm lub voj voog khov-thaw. Qhov sib ntxiv ntawm calcium formate tuaj yeem txhim kho Frost tsis kam ntawm cov cement. Nws tuaj yeem txo cov porosity hauv cov cement, txo qhov nkag mus thiab khov dej hauv cov cement, thiab yog li txo qhov kev pheej hmoo ntawm khov-thaw puas. Tsis tas li ntawd, calcium formate kuj tuaj yeem ua rau kom cov cement ntau thiab txhim khu kev tiv thaiv ntawm cov cement rau Frost hnyav hnyav.
4. Txhim kho corrosion kuj ntawm cement
Hauv qee qhov chaw tshwj xeeb, cov khoom siv cement yuav tsum muaj kev tiv thaiv corrosion zoo. Calcium formate tuaj yeem cuam tshuam nrog calcium hydroxide hauv cov cement los tsim cov khoom uas tsis yooj yim corroded, yog li txhim kho corrosion kuj ntawm cement. Nyob rau tib lub sijhawm, calcium formate tuaj yeem txo cov permeability ntawm cov cement thiab txo qhov yaig ntawm cov cement los ntawm corrosive media.
Calcium formateplays lub luag haujlwm tseem ceeb hauv cov cement hauv kev ua kom cov tshuaj tiv thaiv hydration, txhim kho lub zog thaum ntxov, txhim kho Frost tsis kam thiab txhim kho corrosion kuj. Hauv kev tsim thiab siv cov cement, kev siv cov calcium formate tuaj yeem txhim kho kev ua haujlwm ntawm cov cement thiab ua tau raws li qhov xav tau ntawm cov haujlwm sib txawv.
