Using only waste glass as a tile raw material, the ball was milled, dried, molded and sintered at low temperature to produce a tile. The glass can cover the waste dust, so that heavy metal leaching can be suppressed below the environmental standard.

Description

제철소 폐분진과 폐유리를 원료로 사용한 타일 제조법Tile manufacturing method using waste dust and waste glass as raw materials

본 발명은 산업폐기물의 재활용에 관한 것으로 폐기물인 제철소 폐분진과 폐유리를 원료로 사용한 타일제조 방법에 관한 것이다.The present invention relates to the recycling of industrial wastes and to a tile manufacturing method using waste steel and dust as waste as raw materials.

산업 폐기물의 재활용에 관한 연구는 시멘트 원료로 제철소 폐분진을 사용하는 법 등이 개발되어 있고 폐기물안에 함유되어 있는 중금속 유출방지에 관한 연구도 진행되고 있으나 더 많은 연구가 필요한 실정이다. 일반적으로 타일 제조시에는 규석, 점토등의 요업원료가 사용되며 타일생산비에서 요업원료가 차지하는 비율이 20~30%나 된다.Research on the recycling of industrial wastes has been developed to use waste dust from steel mills as a raw material for cement, and research on the prevention of heavy metals contained in wastes is underway, but more research is needed. Generally, ceramic raw materials such as silica and clay are used in tile manufacturing, and the ratio of ceramic raw materials to tile production costs is 20-30%.

본 발명은 타일생산비에서 상당한 비중을 차지하는 원료비를 줄이기 위해서 100% 산업폐기물만을 원료로 사용한 타일제조방법을 제공하는데 목적이 있다.An object of the present invention is to provide a tile manufacturing method using only 100% industrial waste as a raw material in order to reduce the raw material cost, which occupies a considerable proportion in the tile production cost.

본 발명의 또 다른 목적은 산업 폐기물을 타일 원료로 사용할 때 제철소 폐진분에 함유되어 있는 중금속의 용출을 최대한 억제하는데 그 목적이 있다.Another object of the present invention is to suppress the elution of heavy metals contained in waste mills in steel mills when industrial waste is used as a tile material.

본 발명에서는 제철소 폐분진에 10~50 중량부 폐유리를 첨가하여 물을 용매로 하여 5시간동안 볼 밀링(ball milling)을 하였고, 이 슬러리를 100 매쉬체로 통과시킨후 건조 시켰으며, 이 원료를 가압하여 타일로 성형하였다. 성형된 타일을 로(furnace)에서 1050℃~1100℃ 사이에 0분 또는 30분씩 유지하여 소성하였다.In the present invention, 10 to 50 parts by weight of waste glass was added to the waste mill, and water was used as a solvent for ball milling for 5 hours, and the slurry was passed through a 100 mesh sieve and dried. Pressurized into a tile. The molded tiles were fired by maintaining 0 or 30 minutes between 1050 ° C. and 1100 ° C. in a furnace.

소성한 타일의 열처리 조건에 따른 흡수율 측정결과를 보면, 소결시간이 0분일때는 1050℃에서는 50중량부 폐유리 함유 시편과 1065℃에서는 40, 50중량부 폐유리 함유 시편과 1075℃에서는 40중량부 폐유리 함유 시편이 1% 이하의 흡수율을 보였다.As a result of measuring the absorption rate according to the heat treatment condition of the calcined tile, when the sintering time is 0 minutes, the sample containing 50 parts by weight of waste glass at 1050 ° C, the sample containing 40 parts by weight at 1065 ° C and the weight of 40 parts by weight at 1075 ° C Secondary glass containing specimens had an absorption of less than 1%.

소결시간이 30분일 경우는 1050℃에서는 40중량부 폐유리 함유 시편과 1065℃, 1080℃에서는 30, 40중량부 폐유리 함유 시편이 1% 이하의 흡수율을 보였다. X-선 회절분석(XRD)을 소결전 시편과 소결후 시편에 실시하였으며, 이때 조성의 변화가 없는 것으로 판독되었고 주사전자현미경으로 시편의 파단면을 분석한 결과 유리질이 폐분진 입자를 감싸고 있음을 확인할 수 있었고 이 유리질, 즉 폐유리가 함유되었기 때문에 타일의 소결온도를 100℃ 가까이 낮출 수 있었다.At 30 minutes of sintering time, 40 parts by weight of waste glass containing specimens at 1050 ° C and 30 and 40 parts by weight of waste glass containing specimens at 1065 ° C and 1080 ° C showed absorption rates of 1% or less. X-ray diffraction analysis (XRD) was performed on the pre-sintered and post-sintered specimens. At this time, it was read that there was no change in composition and the fracture surface of the specimen was analyzed by scanning electron microscope. It was confirmed that this glass, that is, waste glass, could lower the sintering temperature of the tile to 100 ° C.

표 1은 중금속 용출방법인 독극물 특성 용출법(Toxicitic Characteristics Leaching Procedure)에 의한 용출실험 결과이며 소정전 폐분진의 중금속 함유량이 기준치의 수십배 이었으나 소성후에는 중금속 용출량이 기준치 이하로 나와서 환경학적으로도 안전함을 알 수 있었다.Table 1 shows the results of the dissolution test using the Toxicitic Characteristics Leaching Procedure, which is a heavy metal leaching method. And it was found.

[표 1] 용출실험결과[Table 1] Dissolution test results

상술한 바와 같이 본 발명은 100% 산업폐기물을 타일의 원료로 사용하고 비교적 낮은 온도에서 소성하여 타일을 제조할 수 있어서 산업 폐기물의 재활용과 함께 타일 제조 원가를 줄일 수 있었으며, 중금속 용출이 기준치 이하여서 환경학적으로도 안전한 타일을 제조할 수 있는 등의 작용효과가 있다.As described above, according to the present invention, since 100% industrial waste is used as a raw material of the tile and the tile can be manufactured by firing at a relatively low temperature, the production cost of the tile can be reduced together with the recycling of industrial waste. There is an effect such as to be able to manufacture environmentally safe tiles.
