본 발명은 석탄재(Ash), 폐 주물사(molding sand)를 이용한 친환경적인 유리(Glass)를 제조하는 방법에 관한 것이다. 그동안 화력발전소는 경제성장과 더불어 에너지산업의 성장을 이끌어왔다. The present invention relates to a method of manufacturing an environmentally friendly glass using a coal ash and a molding sand. In the meantime, coal-fired power plants have led the growth of the energy industry with economic growth.
그러나 화력발전소에서 발생된 석탄재(Ash)와 산업현장에서 발생한 폐 주물사(molding sand)는 중금속이 함유된 폐기물로 화력발전소 주변의 바다에 매립에 의존하고 있는 관계로 매립장의 포화상태와 자연환경을 파괴하는 요인이 되고 있다. 특히 석탄재(Ash)를 매립하는 이송단계에서 물과 혼합 파이프로 이송매립 하므로 오염된 물의 배수로 인해 중금속이 무방비상태로 바다로 흘러들어가 오염을 가중시키는 실정이다. However, coal ash generated from thermal power plants and molding sand generated from industrial sites are heavy metal-containing wastes, and they depend on landfilling in the seas around thermal power plants, destroying the saturation and natural environment of the landfill. . Particularly, since the ash is buried in the water and the mixed pipe in the transfer step of filling the ash, the heavy metal flows into the sea due to the drainage of the contaminated water, and the pollution is increased.
지금까지 석탄재(Ash)는 벽돌, 토건재료, 레미콘 또는 광물성 섬유 등의 원료로 사용하고 있으나 기술개발은 계속 연구 중으로 국내에서도 석탄재(Ash)의 Sio2 물질을 활용한 광물성 섬유를 제조하는 기술이 최근 개발되어 상용단계에 있으며 폐자원을 재활용한 유리(Glass)를 제조하는 방법으로 석탄재(Ash)에 Sio2, Al2O3 및 Fe2O3의 성분은 유리(Glass)제조물질의 최상조건으로 이를 재활용하는 수단으로 기술적 의의가 있으며 폐기물의 재활용 및 자연 환경보호 등 녹색에너지산업을 이끌 신기술이다.So far, coal ash has been used as a raw material for bricks, civil engineering materials, remicon or mineral fiber, but the technology development is still being studied.

It is a technical means to recycle Sio2, Al2O3, and Fe2O3 as the best condition for glass manufacturing materials. It is a new technology that will lead the green energy industry such as waste recycling and protection of the natural environment.
본 발명은 현재 국내 화력발전소에서 발생된 석탄재(Ash)는 매립장에 매립하여 놓은 석탄재(Ash) 또는 폐 주물사(moldingsand)의 폐자원에서 Sio2, Al2O3 및 Fe2O3을 재활용하는 유리(Glass)제조 수단으로써, 석탄재(Ash)와 규산나트륨을 혼합하여 20~30mm의 크기로 성형단계와 석탄재(Ash) 40중량%, 주물사(molding sand) 10중량%, 석회석(CaCo3) 30중량%, 소다회(Na2O) 10중량%, 파유리(Cullet) 10중량%를 배합, 용해, 성형, 서냉, 가공, 검사 및 포장단계로 유리(Glass)를 제조하는 방법을 연구하였다.The present invention relates to a method for manufacturing glass which recycles Sio2, Al2O3 and Fe2O3 from waste materials of coal ash or moldingsand buried in a landfill, Ash (ash) and sodium silicate were blended to obtain a molding step having a size of 20 to 30 mm and a molding step of 40 wt% of ash, 10 wt% of molding sand, 30 wt% of limestone (CaCo 3) And 10% by weight of Cullet were mixed and melted, molded, slowly cooled, processed, inspected and packaged to prepare glass.
본 발명은 폐자원에서 Sio2, Al2O3 및 Fe2O3을 재활용하여 유리(Glass)제조하는 방법을 제공하기 위한 것으로 제품에 다양한 성질이 있는 유리(Glass)를 만드는 연구와 실험을 통하여 제품에 변성과 색상에서 나오는 빛깔을 연구 개발하여야 할 것이다.The present invention provides a method for manufacturing glass by recycling Sio2, Al2O3, and Fe2O3 in waste resources. The present invention relates to a method of manufacturing a glass having various properties, It is necessary to research and develop the color.
화력발전소에서 배출되는 석탄재(Ash)는 악성폐기물로 석탄재(Ash)의 특성상 산화물이 침전되어 수질악화로 생태계를 파괴하는 환경문제가 발생하나 폐자원을 재활용하는 본 발명에 의해서 제공되는 유리(Glass)제조로 유리세공품, 유리병, 판유리, 유리구슬, 유리섬유 및 초자기구 등 다양한 소재로 사용되고, 특히 석탄재(Ash)에서 재활용되는 Sio2, Al2O3 및 Fe2O3의 성분으로 인해 용융 시 나타내는 예술적 가치를 높이는 특유의 색상과 빛깔은 예술적 가치가 충분하며 또한 폐자원의 재활용으로 인하여 원가저하와 고효율 등으로 여러 산업분야에서 유용하게 사용될 발명인 것이다.The ash discharged from the thermal power plant is malignant waste, which is an environmental problem that oxides are precipitated due to the nature of coal ash and deteriorates the ecosystem due to deterioration of the water quality. However, the glass provided by the present invention, It is used in various materials such as glass artifacts, glass bottles, plate glass, glass beads, glass fiber and glassware, and especially the components of Sio2, Al2O3 and Fe2O3 recycled from ash. Color and color are artistic values, and because of the recycling of waste resources, cost reduction and high efficiency are the inventions that will be useful in various industrial fields.
본 발명에 따른 석탄재(Ash) 또는 폐 주물사(molding sand)는 폐자원을 재활용함으로써 오염배출량을 줄여 21세기의 녹색성장에 크게 기여할 것이다.The ash or the molding sand according to the present invention will greatly contribute to the green growth of the 21st century by reducing the amount of pollution emissions by recycling waste resources.
