Calcium Formate (Ca(HCOO)₂) muSimende Hydration: Mhedzisiro uye Maitiro

Calcium formate (Ca(HCOO)₂), chinhu chinobva mukugadzirwa kwepolyol, chinoshandiswa zvakanyanya mu simende sechinhu chinokurumidzisa kupinza zvinhu nekukurumidza, chinozora mafuta, uye chinosimudzira simba rekutanga, zvichideredza nguva yekuomesa zvinhu uye zvinokurumidzisa kupinza zvinhu.

Musimende yePortland yakajairika, Ca(HCOO)₂ inosimudzira kunyorova kweC3S (triccalcium silicate) uye inowedzera kuumbwa kweetringite (AFt), nokudaro ichisimbisa simba rekutanga. Zvisinei, simba rayo pakunyorova kwesimende yesulphoaluminate (SAC) harisati raongororwa.

Muchidzidzo ichi, takaongorora kukanganiswa kweCa(HCOO)₂ pakunyoroveswa kweSAC nekukurumidza nekuongorora:

• Kuisa nguva
• Kupisa kwemvura
• XRD (X-ray diffraction)
• TG-DSC (thermogravimetric-differential scanning calorimetry)
• SEM (kuskena maikorosikopu emaerekitironi)

Zvakawanikwa izvi zvinopa ruzivo pamusoro pekushanda kweCa(HCOO)₂ muSAC hydration, zvichibatsira pakunzwisisa kwakadzama mashandiro ayo mune dzimwe nzira dzesimende.

Dzvanya apa kuti uwane mutengo wakaderedzwa we calcium formate.

Mikana yekuchengetedza mari yekutenga Calcium formate!
