초록

소다석회 조성의 폐 유리를 발포유리의 원료로 활용하기 위해 폐유리의 가수분해를 시도하였다. 소다석회유리 조성으로 만들어진 판유리 및 병 유리 등은 공히 가압 하에서 증기상의 물 또는 액체상의 물에 의해 효율적으로 가수분해가 진행되었다. 최적의 가수분해의 조건은 공히 250 ℃, 2 h이었으며 이 조건하에 얻어진 수화유리의 함수율은 발포유리의 원료유리로서 발포화가 가능한 7.85~10.04%였다. 수식제인 Na성분은 액상의 물에 의한 가수 분해에 효율적이며 유시시료에 대한 중량비로서 0.04첨가 시 가장 높은 함수율을 지닌 수화유리가 얻어졌다.

Hydrolysis of soda-lime waste glass was investigated to test the feasibility for use of waste glass as feed material in the production of foamed glass. The soda-lime glass, such as plate glass and various bottle glasses, was effectively hydrolyzed by steam and water under high pressure. The proper condition for the hydrolysis was found to be reaction temperature of 250 ℃ and reaction time of 2 h. Under this condition, the water content of hydrated glass through hydrolysis was 7.85~10.04%, allowing successful foaming process for production of foamed glass. Using Na as the modifying agent of glass was effective in the hydrolysis by water. The highest water content of hydrated glass was obtained when weight ratio of NaOH to the glass was 0.04.

Keywords:waste glass;foamed glass;insulating construction material;hydrolysis;recycling
