Calcium formateraws li hom tshiab ntawm cov neeg sawv cev thaum ntxov muaj zog muaj ob lub luag haujlwm.
Nws tuaj yeem tsis tsuas yog ua kom lub zog ceev ntawm cov cement, txhim kho lub zog thaum ntxov, tab sis kuj zam kev tsim kho thaum lub caij ntuj no los yog qis kub thiab av noo, qhov chaw ceev yog qeeb heev, kom cov khoom cement tuaj yeem siv tau sai li sai tau. ua tau los txhim kho lub zog, tshwj xeeb tshaj yog thaum ntxov muaj zog pab.
Tau ntev, calcium chloride tau siv rau hauv qhov project, tab sis calcium chloride muaj cov nyhuv corroding steel tuav, thiab chlorine dawb coagulant tau tsim nyob rau hauv tsev thiab txawv teb chaws.Calcium formateyog ib yam tshiab ntawm cov khoom siv zog thaum ntxov, uas tuaj yeem ua kom cov dej ntawm calcium silicate C3S hauv cov cement thiab ua kom lub zog thaum ntxov ntawm cov cement mortar, tab sis nws yuav tsis ua rau corrosion rau steel tuav los yog ua paug rau ib puag ncig. Yog li ntawd, nws kuj yog siv dav hauv oilfield drilling thiab cementing.
Khoom nta Ua kom lub zog ntawm cov cement thiab ua kom lub sijhawm tsim kho. Txo lub sij hawm teem caij, tsim ntxov.
Txhim kho lub zog thaum ntxov ntawm mortar ntawm qhov kub thiab txias. Antifreeze thiab xeb. Technical Properties thiab cov yam ntxwvCalcium formateyog dawb los yog tawm-dawb crystalline hmoov.
Raws li cov txheej txheem kho, cov khoom no tuaj yeem ua pob zeb hauv 4 xuab moos kawg solidification. Hauv li 8 teev, nws lub zog tuaj yeem ncav cuag ntau dua 5Mpa, uas tuaj yeem ua rau cov pob zeb cam khwb cia hauv qhov chaw ua tiav. Thaum ua kom ntseeg tau lub zog thaum ntxov ntawm mortar thiab pob zeb, lub zog lig ntawm mortar thiab pob zeb tuaj yeem nce ib txwm, thiab tsis muaj kev puas tsuaj rau lwm yam khoom ntawm mortar thiab pob zeb.
Muaj feem xyuam rau cov nplais pobzeb binder, cement-based plastering mortar, kho mortar, waterproof mortar, rwb thaiv tsev mortar hnav-resistant pem teb thiab putty thiab lwm yam khoom, tuaj yeem txhim kho cov khoom ntom ntom thiab txuas ntxiv lub sijhawm qhib ntawmcalcium formatecov ntsiab lus feem ntau tsis tshaj 1.2% ntawm tag nrho cov mortar.
Calcium formateyog incompatible nrog lwm yam auxiliaries, thiab muaj peev xwm muab sib tov tusyees nrog cement, xuab zeb thiab lwm yam auxiliaries nyob rau hauv ib tug tej yam kev faib ua feem nyob rau hauv lub tov khoom.
