Calcium Formate hauv pob zeb

Calcium Formate

Calcium formate in concrete, also known as calcium citrate, has the molecular formula C2H204Ca. Slightly hygroscopic, with a slightly bitter taste. Neutral, non-toxic, soluble in water. The aqueous solution is neutral. The solubility of calcium formate does not change significantly with increasing temperature, with 16g/100g of water at 0 ℃ and 18.4g/100g of water at 100 ℃. Specific gravity: 2.023 (20 ℃), bulk density 900-1000g/L. Heating decomposition temperature>400 degree.

Lwm lub npe: Calcium formate; Calcium diformate; Calcium formate (Ca (HCO2) 2); Calcoform; formal acid, calcium ntsev; HSDB 5019; Mravencan vapor; Mravencan vapor [Czech]; Formal acid, calcium ntsev (2: 1)

Cov tsos mob: Dawb crystals los yog hmoov

Calcium formate hauv pob zeb yog siv los ua tus neeg sawv cev ceev ceev, lubricant, thiab tus neeg sawv cev thaum ntxov rau cov cement. Siv nyob rau hauv lub tsev mortar thiab ntau yam ntawm cov pob zeb kom ceev lub hardening tus nqi ntawm cov cement, shorten lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv lub caij ntuj no kev tsim kho, kom tsis txhob qeeb qhov chaw ntawm qhov kub thiab txias. Kev demolding ceev tso cai rau cov cement kom nws lub zog thiab muab tso rau hauv kev siv sai li sai tau. Calcium formate siv: ntau yam qhuav sib xyaw mortar, ntau yam pob zeb, cov ntaub ntawv hnav-tiv taus, kev lag luam hauv pem teb, kev lag luam pub, tawv ua. Qhov ntau npaum li cas thiab kev ceev faj rau calcium formate yog li ntawm 0.5 ~ 1.0% ib tuj qhuav hmoov mortar thiab pob zeb, nrog rau qhov siab tshaj plaws ntawm 2.5%. Qhov ntau npaum ntawm calcium formate maj mam nce nrog qhov txo qis ntawm qhov kub thiab txias, thiab txawm tias daim ntawv thov ntawm 0.3-0.5% nyob rau lub caij ntuj sov yuav muaj cov txiaj ntsig tseem ceeb thaum ntxov.

Ntim: 25kg hnab lossis 1200kg hnab loj, 24mt lossis 25mt / fcl.
