Özet
Mekanokimyasal aktivasyon için 9 veya 18 mol karbon nano-tozlar içeren iki farklı sodyum geopolymer iyi bilinen geopolymer yöntemi ile hazırlanmıştır. 9 mol karbon, geopolimer üretimi aşamasında geopolimer reçineye dahil edilirken, 18 mol karbon, geopolimer işleminden sonra üretilen geopolimer ile karıştırılmıştır. NaGP9C ve NaGP18C olarak adlandırılan her iki geopolimer karbon başlangıç malzemesi 24 saat mekanokimyasal olarak aktive edilmiş ve NaGP18C ayrıca 48 saat aktive edilmiştir. Aktivasyon işlemleri 250 dev/dak' da ağırlıkça bilye toz oranı 25:1 olacak şekilde bir gezegen bilyeli değirmende gerçekleştirilmiştir. Aktivasyon ve karbon içeriğine bağlı olarak, sonuç kompozisyonların oda ve yüksek sıcaklık özellikleri optik mikroskop, XRD, SEM ve DSC analizleri yapılarak değerlendirildi.
Two different sodium geopolymers including 9 or 18 moles carbon nano-powder were prepared for mechanochemical activation by using the well-known geopolymer route. While 9 moles carbon were incorporated into geopolymer resin during the geopolymer route, 18 moles carbon were mixed with produced geopolymer after the geopolymer route. Both geopolymer carbon precursors named as NaGP9C and NaGP18C were mechanochemically activated for 24 hours and, the NaGP18C was also activated for 48 hours. Activation processes were carried out in a planetary ball mill with a ball to powder wt % ratio of 25:1 at 250 rpm. Depending on the activation and carbon content, room and high temperature properties of resultant compositions were evaluated by making optical microscope, XRD, SEM and DSC analyses.
