Calcium Formate
Calcium formate nyob rau hauv cement yog dawb crystalline los yog crystalline hmoov. Calcium formate nyob rau hauv cov cement, uas yog siv thaum ntxov muaj zog tus neeg sawv cev los txhim kho lub zog thaum ntxov ntawm cov cement, yog dav siv nyob rau hauv qhuav hmoov mortar. Nws muaj qhov ua tau zoo ntawm kev ua kom dej nrawm thiab txhim kho lub zog thaum ntxov ntawm mortar, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias, calcium formate tuaj yeem txhim kho lub zog thaum ntxov ntawm mortar.

Raws li hom tshiab ntawm lub zog thaum ntxov, calcium formate hauv cov cement muaj ob lub luag haujlwm, uas tuaj yeem ua kom lub zog ceev ntawm cov cement, txhim kho lub zog thaum ntxov, thiab zam kev tsim kho thaum lub caij ntuj no los yog kub thiab av noo, qhov teeb tsa qeeb dhau. , yog li cov khoom siv cement tuaj yeem muab tso rau hauv kev siv sai li sai tau los txhim kho lub zog ntawm lub zog thaum ntxov.Rau lub sijhawm 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 formate yog 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 ib puag ncig. kuj tau dav siv nyob rau hauv oilfield drilling thiab cementing.Product nta Ceev kom lub hardening ntawm cov cement thiab shorten lub sij hawm tsim kho.Shorten lub sij hawm, thaum ntxov forming.Txhim kho lub zog thaum ntxov ntawm mortar ntawm tsawg kub.Antifreeze thiab rust.Technical Properties thiab zog Calcium formate yog dawb los yog dawb crystalline hmoov.Raws li tus qauv curing tej yam kev mob, cov khoom yuav ua rau cov pob zeb zaum kawg teem nyob rau hauv 4 teev.In hais txog 8 teev, nws lub zog muaj peev xwm ncav cuag ntau tshaj 5Mpa, uas yuav ua rau cov cam khwb cia-hauv-qhov chaw pob zeb. Ua tiav demoulded.Thaum ua kom 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.Tshwj xeeb rau cov nplais pobzeb, 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 ntawm calcium formate cov ntsiab lus feem ntau tsis tshaj 1.2% ntawm tag nrho cov mortar.Calcium formate yog incompatible nrog rau lwm yam. auxiliaries, thiab tuaj yeem sib tov sib npaug nrog cov cement, xuab zeb thiab lwm yam auxiliaries nyob rau hauv ib qho kev faib ua feem ntawm lub tov khoom.
