Gịnị ka calcium formate mee ngwangwa ntọala na hardening nke ihe pụtara kpọmkwem?

Calcium usorobụ ntụ ntụ na-acha ọcha ma ọ bụ ntakịrị odo odo, nke nwere ike ime ka ọsọ hydration nke ciment dị ngwa ma zere nsogbu nke ngwa ngwa ngwa ngwa n'oge oyi ma ọ bụ obere okpomọkụ na ọnọdụ mmiri, iji mee ka ike mbụ nke ngwa agha dịkwuo mma. Taa ka m ga-agwa gị maka yausoro nke calcium iji mee ngwangwa ntọala na hardening nke ihe bụ kpọmkwem?

Calcium usoro na-eme ka ntọala na ike siri ike nke ihe dị ngwa site na:

1. Mee ka oge ntọala mbụ dị mkpụmkpụ

2. Normalize ngwa ngwa ntọala ciment n'okpuru ọnọdụ okpomọkụ dị ala

3. Mụbaa mmụba nke ike mmalite

4. Mbelata oge mmechi na modul na mmepụta nke ihe ndị a na-emepụta ihe na-emepụta ihe

5. Na-ebelata oge maka kọmpụta iji ruo ikike ibu ya

Dịka ọmụmaatụ, a na-ejikarị simenti Portland eme ihe na ngwa ngwa akọrọ, nke a na-eji ike dị ala na mmalite na ike dị elu n'oge ikpeazụ, na ịgbakwunye usoro calcium kwesịrị ekwesị bara uru iji meziwanye ike mmalite nke ngwaahịa ahụ.

Na simenti Portland,usoro nke calcium nwere mmetụta nke ịkwalite coagulation na ike mmalite, n'ihi na ion formate na HCOO- nwere ike ịmepụta myirịta nke AHt na AFm (C).A·3Ca (HCOO)30HOCA·Ca(HCOO)·10H0, wdg), nke na-ebelata oge nhazi nke ciment.

Na mgbakwunye,usoro nke calciumnwere ike ịkwalite hydration nke calcium silicate, n'ihi na HCOO-ions na-agbasa ngwa ngwa karịa Ca2 + ion, ma nwee ike banye n'ime oyi akwa nke C3S na C2S, na-eme ka mmiri ozuzo Ca (OH) dịkwuo elu.na ire ere nke calcium silicate. HCOO-ion nwekwara ike na-ekekọta silicon atọm iji meghachi omume na OH- site na kemịkalụ omume, ka ịgafe njikọ n'akụkụ silicate otu, kwalite nguzobe nke CSH gel, na melite ike siri ike nke ciment ngwa agha.
