Method for Manufacturing Water Glass Using Rice Husk or Rice Husk Ash
The present invention relates to a method for producing a water glass having a high content of amorphous silicon dioxide by conducting a reaction of rice husk or rice husk ash. The water glass manufactured by the method of the present invention is manufactured by conducting a reaction of rice husk, an agricultural by-product as a main raw material, at a low temperature, so that material cost and energy consumption are lower than an existing water glass manufacturing process which uses sand as a raw material. In addition, manufactured water glass has a high silicon dioxide content compared to sodium oxide, thereby having excellent quality, and an amorphous content is high, thereby having a wide application range.
본 발명은 왕겨 또는 왕겨재를 탄산나트륨과 반응시켜 비정질 이산화규소 성분 함량이 높은 물유리를 제조하는 방법에 관한 것이다. 본 발명의 방법으로 제조되는 물유리는 농업부산물인 왕겨를 주원료로 하여 낮은 온도에서 반응시켜 제조되므로 종래의 모래를 원료로 하는 물유리 제조공정에 비해 재료비와 에너지 소비가 적어서 제조비용을 낮출 수 있으며, 또한 제조된 물유리는 산화나트륨 대비 이산화규소의 함량이 높아서 품질이 우수하고 비정질 함량이 높으므로 응용범위가 넓은 장점이 있다.
