Te Konupūmā Formate (Ca(HCOO)₂) i roto i te Whakamakuku Sima: Ngā Pānga me ngā Tikanga

Ko te konupūmā formate (Ca(HCOO)₂), he hua taha o te hanga polyol, e whakamahia whānuitia ana i roto i te sima hei whakatere tere, hei hinu whakahinuhinu, hei whakarei ake hoki i te kaha mō te wā wawe, e whakapoto ana i te wā whakapakeke me te whakatere tere ake i te taunga.

I roto i te sima Portland noa, ka whakatairangahia e Ca(HCOO)₂ te whakamakuku o te C3S (tricalcium silicate) me te whakanui ake i te hanganga o te ettringite (AFt), ā, ka whakarei ake i te kaha tōmua. Heoi, kāore anō kia tūhuratia tōna awe ki te whakamakuku o te sima sulphoaluminate (SAC).

I roto i tēnei rangahau, i tirotirohia e mātou te pānga o te Ca(HCOO)₂ ki te whakamakuku wawe o te SAC mā te tātari i:

• Te wā whakatakoto
• Te wera whakamakuku
• XRD (whakawhitinga hihi-X)
• TG-DSC (whakamātautau ine pāmahana-rerekētanga matawai)
• SEM (māka tirotiro hikohiko)

Mā ngā kitenga ka mārama ki te tikanga mahi a Ca(HCOO)₂ i roto i te whakawaiwai SAC, ka whai wāhi atu ki te māramatanga hohonu ake ki tōna mahi i roto i ngā pūnaha sima rerekē.
