초록
This study is an experimental attempt to confirm the binder effect of zeolite coating on glass plate byheat treatment. As a result, zeolite was successfully formed with low concentratios of pressure, whose concentrationwas effective in 10% or more for thin film zeolite coating. And as the content of the binder (TEOS)in mixed coating solution was higher, the zeolite was fastened better on the surface. Above 5% content ofthe binder in the coating solution, TEOS hindered zeolite synthesis of the precursor and brought to zeolitecapacity decrease. Furthermore, when the concentration of the precursor, sedimentation rate of the precursorwas higher and the coating efficiency is reduced thereby. Therefore, the most effective concentrations ofthe precursor and TEOS in the coating solution was 10% and 5%, respectively. It was concluded that zeolitecoating is produced by heat treatment method after dipping without hydrothermal synthesis.
