Calcium formate manufacturersAojin Chemical qhia nrog koj cov ntawv thov ntawm calcium formate hauv kev tsim kho cement kev lag luam. Cov calcium formate muag los ntawm Aojin Chemical muaj cov ntsiab lus siab ntawm 98% thiab tau ntim rau hauv 25kg / hnab.
Calcium formate chaw tsim tshuaj paus Aojin Chemical qhia nws cov ntawv thov hauv kev tsim kho cement. Aojin Chemical muag calcium formate nrog siab 98% cov ntsiab lus, ntim rau hauv 25kg hnab.
Calcium formate (Ca(HCOO)₂), yog ib qho zoo heev cov organic thaum ntxov-lub zog tus neeg sawv cev, yog siv nyob rau hauv zus tau tej cov pob zeb thiab cement khoom vim nws cov yam ntxwv tshuaj. Nws lub luag haujlwm tseem ceeb thiab kev siv yog raws li hauv qab no:
1. Thaum ntxov muaj zog thiab teeb tsa nrawm
Calcium formate ho accelerates cement hydration, tshwj xeeb tshaj yog cov hydration ntawm tricalcium silicate (C₃S) thiab tricalcium aluminate (C₃A). Qhov no ua kom lub zog tsim thiab teeb tsa cov khoom hydration (xws li ettringite thiab calcium hydroxide), yog li txhim kho lub zog thaum ntxov ntawm cov khoom siv cement (lub zog tuaj yeem nce 20% -50% hauv 1-7 hnub). Cov cuab yeej no ua rau nws tsim nyog rau kev tsim kho qhov kub thiab txias (xws li lub caij ntuj no pouring) los yog kev kho thaum muaj xwm txheej ceev, txo lub sij hawm kho thiab xyuas kom cov pob zeb hardens ib txwm nyob rau hauv ib puag ncig uas tsis kub, yog li tiv thaiv kev puas tsuaj.
2. Txhim kho pob zeb ua haujlwm thiab ua haujlwm ntev
Nyob rau hauv cov cement paste, calcium formate txo cov ntshav thiab kev sib cais, txhim kho pob zeb homogeneity thiab ntom. Tsis tas li ntawd, nws cov khoom hydration sau cov pores ntawm cov cement paste, txo cov porosity, indirectly txhim kho cov pob zeb impermeability, Frost tsis kam, thiab corrosion kuj, yog li ncua lub neej kev pab cuam ntawm cement khoom.
3. Haum rau ntau yam khoom siv cement
Nyob rau hauv precast tivthaiv ntau lawm, xws li precast panels thiab yeeb piles, calcium formate accelerates pwm turnover, shortens demolding lub sij hawm, thiab txhim kho efficiency ntau lawm.
Shotcrete: Siv nyob rau hauv txau cov haujlwm hauv tunnels, mines, thiab lwm yam dej num, nws ceev ceev thiab hardens, txo rebound poob thiab txhim kho kev tsim kho efficiency.
mortar thiab masonry cov ntaub ntawv: Nws txhim kho cov dej tuav thiab thaum ntxov lub zog ntawm mortar, ua kom muaj kev vam meej sai hauv cov txheej txheem masonry thiab plastering.
4. Ib puag ncig thiab Compatibility Zoo
Calcium formate Nqeyog tsis muaj tshuaj lom thiab tsis ua rau khaus, thiab yog sib xws nrog cov cement, dej-txo cov neeg ua hauj lwm, ya tshauv, thiab lwm yam admixtures. Nws tsis ua rau muaj teeb meem xws li alkali-tag nrho cov tshuaj tiv thaiv hauv pob zeb, ua kom tau raws li qhov xav tau ntawm kev tsim kho vaj tsev ntsuab. Lus Cim: Cov tshuaj calcium formate yuav tsum tau tswj nruj me ntsis (feem ntau 1% -3% ntawm cov cement loj). Kev sib ntxiv ntau dhau tuaj yeem ua rau cov pob zeb ua kom muaj zog tom qab kev loj hlob thiab tseem ua rau shrinkage tawg. Kev hloov kho yuav tsum tau ua raws li cov xwm txheej xws li qhov project ib puag ncig thiab hom cement.
