Özet:
Hollow nano calcite particles were used as a core material in vacuum insulation panels (VIPs) and compared it with the fumed silica generally used in VIPs as the core material. Zinc-Tin-oxide (ZTO), ZnSnOx, was coated on the polyamide/polyethylene (PA/PE) polymeric films and used as the barrier material in VIPs to prohibit moisture and air transport. A fluidized bed filtration system was developed to separate the produced hollow nano particles from its slurry. ZnSnOx coating on the PA/PE polymeric films were optimized with respect to film rotation rate and oxygen content during film coating. Water permeation rate was measured as 8.32 gday-1m-2 for the commercial Aluminum-PET (Al-PET). The water permeation rate was measured as 1.15 gday-1m-2 for the 90 μm of PA/PE films coated with ZTO in 500 rpm of film rotation rate and 30 sccm Ar + 7.5 sccm O2 feed rate. It was shown that the produced ZTO coated PA/PE films had better barrier properties compared to the commercial Al-PET. The thermal conductivity was measured as 8.63 mWm-1K-1 for 3 wt% hollow nano calcite in 87 wt% of fumed silica compared to that of 9.9 mWm-1K-1 for fumed silica only. It was shown that when 3 wt% of hollow nano calcite were mixed with fumed silica as the core material, better thermal conductivity values were obtained.
