Abstract

본 발명은 비중이 낮되 연마성과 내구성이 향상된 직물 탈색용 경량자갈을 제공하기 위한 것으로서, 경량자갈의 내구성을 증진시키기 위하여 이산화 규소를 주성분으로 한 통상의 경량성 자갈을 농도 10중량% 이내의 나트륨 수용액에 합친 후 600-1200℃의 온도로 소성시킴을 특징으로 한다.The present invention provides a light weight gravel for fabric decoloring which has low specific gravity and improved abrasiveness and durability. In order to improve the durability of light gravel, ordinary lightweight gravel containing silicon dioxide as a main component is mixed with a sodium aqueous solution Followed by baking at a temperature of 600 to 1200 占 폚.
