Description

유리 슬러지를 이용한 경량 골재의 제조방법Method for manufacturing lightweight aggregate using glass sludge

본 발명은 유리 슬러지를 이용한 경량 골재의 제조방법에 관한 것으로, 더욱 상세하게는 브라운관이나 광학 유리 등의 연마시 발생하는 특정 폐기물인 유리 연마 슬러지를 이용하여 건축용 경량 골재를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a lightweight aggregate using glass sludge, and more particularly, to a method for producing a lightweight aggregate for construction using a glass polishing sludge, which is a specific waste generated during the polishing of a cathode ray tube or an optical glass.

최근, 철근 콘크리트 건축물의 구조용 골재로 사용되는 천연 골재의 산출량이 감소하고, 구조물이 대형화 됨에 따라 구조용 골재의 경량화 필요성이 고조되면서 인공 경량 골재의 사용량이 점차 늘고 있는 추세이다.In recent years, as the amount of natural aggregate used as structural aggregate of reinforced concrete buildings has decreased, and as the structure has become larger, the need for lightening of structural aggregate has increased, and the use of artificial lightweight aggregate is increasing.

초기의 경량 골재는 소성시 발포하는 팽창혈암 등을 이용하였으나(대한민국 특허공고 제79-1985호, 일본 특허공고 소41-9023호), 원료 채취에 한계가 있어 비팽창성 요업원료에 유기 또는 무기물의 발포제를 첨가하는 방안이 강구되기도 하였다(대한민국 특허공고 제80-1056호, 일본 특허공고 소48-8449호).In the early lightweight aggregate, expansion shale foamed during firing was used (Korean Patent Publication No. 79-1985, Japanese Patent Publication No. 41-9023), but there was a limit in the extraction of raw materials, and organic or inorganic matters A method of adding a foaming agent has been proposed (Korean Patent Publication No. 80-1056, Japanese Patent Publication No. 48-8449).

한편, 한경보존 문제가 커다란 관심사로 부각되면서 폐기물의 재활용 방안이 여러 방면에서 연구되고 있다.On the other hand, as the issue of conservation of han - gyeong has become a big concern, various ways of recycling waste have been studied.

폐기물 중 소각이 어려운 무기질 폐기물은 지금까지 대부분 매립에 의존해 왔으나, 매립장의 확보가 점차 포화상태에 이름에 따라 이의 처리에 적지 않은 문제가 발생하고 있는 실정이다.Mineral wastes, which are difficult to incinerate in wastes, have been largely dependent on landfill so far. However, the landfill site has become increasingly saturated and there are a lot of problems in handling the wastes.

따라서, 현재는 플라이애쉬나 슬래그, 알루미나 제조시 발생하는 직니, 상수 오니, 하수 오니, 폐유 처리 슬러지 등의 무기질 폐기물을 이용하여 경량 골재를 제조함으로써 폐기물 발생도 줄이고 경제성도 확보할 수 있는 방안이 제안되고 있다(대한민국 특허공고 제73-166호, 제80-1054호, 대한민국 공개특허 제93-9951호, 일본 특허공고 소46-32279호, 일본 특허공고 소50-17093호, 일본 특허공고 소54-8373호, 일본 공개특허 소51-44116호, 일본 공개특허 소51-105327호).Therefore, currently, there is proposed a method to reduce waste generation and economical efficiency by manufacturing lightweight aggregate using inorganic wastes such as fly ash, slag, alumina, tin, water sludge, sewage sludge, and waste oil treated sludge (Korean Patent Publication No. 73-166, No. 80-1054, Korean Patent Publication No. 93-9951, Japanese Patent Publication No. 46-32279, Japanese Patent Publication No. 50-17093, Japanese Patent Publication No. 54 -8373, JP-A-51-44116, JP-A-51-105327).

상기한 무기질 폐기물 중 브라운관이나 광학 유리 등의 연마시 발생하는 유리 연마 슬러지는 연마되는 유리 뿐만 아니라 연마제 등이 함께 섞여 있으며, 특히 납이나 크롬 등의 중금속도 함유하고 있어서 이의 안전한 처리가 쉽지 않다. 이를 안전하게 처리하기 위해서는 현재로서는 시멘트와 함게 콘크리트화 하는 수밖에 없어서 이 유리 연마 슬러지의 처리에 막대한 비용이 소모되고 있다.Among the above-mentioned inorganic wastes, the glass polishing sludge generated during the polishing of a cathode ray tube or an optical glass is not only a glass to be polished but also an abrasive and the like, and contains heavy metals such as lead and chromium. In order to safely treat the glass sludge, it is necessary to convert it into concrete with cement at present.

이에, 본 발명자들은 무기질 폐기물 중 상기한 유리 연마 슬러지를 안정화시켜 재활용할 수 있고 비용을 절감하여 처리할 수 있는 방법을 예의 연구한 결과, 무기질 폐기물인 유리 연마 슬러지를 건축용 경량 골재로서 재활용할 수 있는 방법을 완성하기에 이르렀다.The inventors of the present invention have made intensive studies on a method of stabilizing the glass polishing sludge among the inorganic wastes and capable of recycling the glass polishing sludge and reducing the cost thereof. As a result, they have found that glass polishing sludge as inorganic waste can be recycled as lightweight aggregate for construction I have come to complete the method.

본 발명의 목적은 유리 연마 폐슬러지를 이용한 경량 골재의 제조방법을 제공하는 것이다.An object of the present invention is to provide a method for producing a lightweight aggregate using glass abrasive waste sludge.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 유리 연마 슬러지 100중량부를 교반 탱크에 넣고 교반시키면서 고령토 25 내지 60중량부를 첨가한 후, 상기 혼합물을 스크류 믹서에 넣어 케이크로 만든 다음, 조립기에서 과립화하고, 제조된 과립을 전기로에서 분당 10℃의 승온속도로 1000 내지 1100℃에서 가열하여 제조되는 것을 특징으로 하는 경량 골재의 제조방법인 것이다.In the present invention, 100 parts by weight of glass polishing sludge is added to a stirring tank and 25 to 60 parts by weight of kaolin is added thereto while stirring. The mixture is then made into a cake by a screw mixer, granulated in a granulator, And heating at a temperature elevation rate of 10 ° C at a temperature of 1000 to 1100 ° C to produce a lightweight aggregate.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에서 원료로 사용되는 유리 연마 폐슬러지는 브라운관이나 광학 유리 등의 연마 중에 발생하는 폐기물로서, 70% 이상이 수분이다. 또한, 연마된 미세한 유리가 주성분이기 때문에 점력이 거의 없어서 골재 형상으로의 조립화도 용이하지 않을 뿐만 아니라 조립화된다 하더라도 유리질이기 때문에 소성시 서로 융착하여 골재의 강도 또한 불량하게 된다.Glass abrasive waste sludge used as a raw material in the present invention is waste generated during polishing of a cathode ray tube or an optical glass, and more than 70% is moisture. In addition, since the polished fine glass is a main component, there is almost no point of force, so it is not easy to assemble into an aggregate form, and even if it is assembled, it is fused to fuse upon firing, resulting in poor aggregate strength.

본 발명에 있어서는 유리 폐슬러지에 일정 정도의 점력을 가지는 고령토를 첨가한다.In the present invention, kaolin having a certain level of force is added to the glass waste sludge.

본 발명에 따라 전체 조성에 대하여 고령토를 1/3정도 첨가하면, 유리 연마 슬러지 중의 수분함량을 50% 이하로 저하시켜서 중금속이 함유되어 있는 유리 폐슬러지 중의 수분을 별도의 제거과정 없이 제거할 수 있으므로 바로 골재화할 수 있게 된다. 즉, 종래의 방법에서와 같이 폐슬러지 중의 수분을 별도로 제거하게 되면 제거된 폐수의 별도 처리 과정이 필요한 반면, 본 발명에 따라 고령토를 유리 폐슬러지에 직접 혼합하여 수분이 함유된 채로 조립화하면 조립화된 유리 폐슬러지 과립을 골재 제조공정에서 가열하므로써 증발에 의해 수분이 무해하게 제거되므로 별도의 폐수 처리 공정을 생략할 수 있다.According to the present invention, by adding about one-third of the total amount of kaolin to the entire composition, the water content in the glass polishing sludge can be lowered to 50% or less, and moisture in the glass waste sludge containing heavy metals can be removed without a separate removal process It is possible to aggregate immediately. That is, if the water in the waste sludge is separately removed as in the conventional method, separate treatment of the wastewater removed is required. On the other hand, when the kaolin is mixed with the glass waste sludge according to the present invention, By heating the granulated glass sludge granules in the aggregate manufacturing process, the water is harmlessly removed by evaporation, so that a separate wastewater treatment process can be omitted.

본 발명에 사용되는 고령토는 품질에는 상관이 없으며, 경제적인 측면에서 D급 이하도 사용할 수 있다.The kaolin used in the present invention has no influence on the quality, and it can be used in a level of D or less in terms of economy.

본 발명에 따르면, 고령토는 유리 폐슬러지 100중량부에 대하여 25 내지 60중량부를 사용할 수 있는데, 고령토를 60중량부 이상 사용하면 균질한 혼합을 저해할 수 있다.According to the present invention, kaolin can be used in an amount of 25 to 60 parts by weight based on 100 parts by weight of glass waste sludge. When kaolin is used in an amount of 60 parts by weight or more, homogeneous mixing can be inhibited.

또한, 본 발명에서는 고령토의 균질한 혼합을 위하여 해교제로서 규산소다 1중량부를 사용할 수 있다.Further, in the present invention, 1 part by weight of sodium silicate may be used as a peptizing agent for homogeneous mixing of kaolin.

본 발명에 다르면, 먼저 브라운관 등의 연마시에 발생하는 유리 연마 슬러지를 교반 탱크에 넣어 교반시키면서 상기 유리 연마 슬러지 100중량부에 대하여 고령토를 25 내지 60중량부 첨가한다. 이 혼합물을 누들 형태의 압출기나 콘형 조립기, 또는 회전요에서 1 내지 3cm 정도의 구형으로 조립화한 다음, 얻어진 조립을 별도의 건조 공정없이 1000 내지 1100℃의 온도로 급속히 소성하면 표면만 유리화된, 비중이 1 내지 2g/cm3정도인 발포된 경량골재를 제조할 수 있다.According to the present invention, 25 to 60 parts by weight of kaolin is added to 100 parts by weight of the glass polishing sludge while stirring the glass polishing sludge generated at the time of polishing a cathode ray tube or the like in a stirring tank. This mixture is assembled into a noodle-type extruder, a cone-type granulator, or a sphere having a size of about 1 to 3 cm at a rotating shaft, and then the resulting granulation is rapidly fired at a temperature of 1000 to 1100 ° C without a separate drying step, A foamed lightweight aggregate having a specific gravity of about 1 to 2 g / cm < 3 > can be produced.

본 발명의 방법에 따라 제조된 경량 골재에 시멘트와 모래를 혼합하여 얇은 판상으로 성형한 다음, 표면부에 불소 페인트를 도포하여 경량 판넬을 제조할 수 있다.The lightweight aggregate produced according to the method of the present invention can be mixed with cement and sand to form a thin plate, and then a fluorine paint may be applied to the surface to produce a lightweight panel.

본 발명의 방법에 따르면, 무기질 폐기물인 유리 연마 슬러지의 막대한 처리 비용을 절감할 수 있을 뿐만 아니라, 유리 연마 슬러지를 경량 골재로 안정화시켜 건축용 골재로 재활용할 수 있다.According to the method of the present invention, not only a great treatment cost of the glass polishing sludge as the inorganic waste can be reduced, but also the glass polishing sludge can be stabilized with the lightweight aggregate and can be recycled as the aggregate for building.
