Description
현재 사용중인 보차도용 조립식 블록은 거의 시멘트, 모래, 자갈의 혼합물을 고압으로 성형, 건조하여 제작되는데, 이들은 획일적인 시멘트의 원색과 형상의 수준을 벗어나지 못한 지극히 낮은 기술로 생산되고 있는 실정이고 자연 친화적인 제품이 되지 못하는 문제를 안고 있다. 한편, 시멘트 조립식 블록을 대체할 수 있는 제품이 없는 것이 아니라 세라믹을 주원료로 하여 생산할 때 양질의 제품을 얻을 수는 있으나 재료의 단가가 고가이기 때문에 시멘트 제품에 비해 월등히 높은 제조원가가 소요되어 시장경쟁력을 확보할 수 없기 때문이다.Currently used prefabricated blocks are manufactured by molding and drying a mixture of cement, sand, and gravel under high pressure, and they are produced with extremely low technology that is beyond the level of primary color and shape of uniform cement. We are having problem that is not product. On the other hand, there is no product that can replace cement prefabricated blocks, but it is possible to obtain high-quality products when producing ceramics as the main raw material. However, due to the high cost of materials, manufacturing costs are significantly higher than those of cement products. This is because it cannot be secured.
그러므로 폐자재를 재활용하는 신기술의 개발로 인한 복합 세라믹스 소재의 보차도 조립식 블록은 획일적인 시멘트 블록과는 달리 세라믹 자체의 은은한 색상을 유지하는 상태에서 여러가지 색소를 첨가하여 거리문화의 분위기를 쇄신시킬 수 있을 것으로 보인다. 또한 다양한 용도에 따라서 다양한 디자인과 주위의 분위기에 가장 적절한 무늬 및 색상을 조화시켜 시멘트 문화를 획기적으로 변화시킬 수 있을 것이다.Therefore, the prefabricated block of composite ceramics material developed by the development of new technology to recycle waste materials, unlike the monolithic cement block, can reinvent the street culture by adding various pigments while maintaining the subtle color of the ceramic itself. Seems to be. In addition, it is possible to change the cement culture by harmonizing patterns and colors that are most appropriate for various designs and surrounding atmospheres according to various uses.
이에 본 발명인은 인체에 무해하고 원적외선의 방출효과와 단열 및 보온성이 탁월하며 재료의 수급에 큰 문제가 없을뿐만 아니라 단가 또한 저렴한 세라믹재를 사용하여 보차도용 조립식 블록을 제조할 수 있는 방법을 연구하던 중 흔히 버려지는 폐내화물이나 폐도자기, 폐타일 등을 경제적으로 최대한의 효과를 거둘 수 있도록 재활용할 수 있는 방법을 안출하기에 이르렀다.Therefore, the inventors of the present invention have been researching a method for manufacturing prefabricated blocks for pavement using a ceramic material that is harmless to the human body, has excellent emission effect of far infrared rays, excellent thermal insulation and thermal insulation, and there is no big problem in supply and demand of materials. Among them, they have come up with ways to recycle waste refractories, waste ceramics, and waste tiles that can be economically maximized.
양질의 세라믹으로 이루어진 내화물이나 도자기, 타일 등을 생산할 때 그 원료를 70% 이상 수입에 의존하고 있다. 그리고 폐내화물이나 폐도자기, 폐타일 등은 일부 수거하여 재활용을 하고는 있지만 재활용률이 극히 낮으며 손쉬운 방법으로써 거의 폐기처분되고 있는 실정이다. 그런데 상기 폐자재들은 산업폐기물로 분류가 되어 처리에 많은 어려움이 수반되고 이에 따라 막대한 비용이 지출되고 있지만 폐기처분의 효과는 매우 미미한 상태이다. 이에 본 발명은 상술한 폐자재들을 적극 재활용하여 이들 폐자재를 주원료로 하는 블록을 제공키 위해 안출된 것이다.When producing refractory, ceramics, tiles, etc. made of high-quality ceramics, they rely on imports of more than 70% of their raw materials. In addition, waste refractories, waste ceramics, and waste tiles are collected and recycled, but the recycling rate is extremely low and is disposed of as an easy method. By the way, the waste materials are classified as industrial wastes, which involves a lot of difficulties in the treatment and accordingly a huge cost, but the effect of disposal is very small. Accordingly, the present invention is devised to provide a block containing these waste materials as a main raw material by actively recycling the waste materials described above.
따라서 본 발명은, 산업폐기물로 분류된 폐내화물이나 폐타일, 폐도자기를 재활용하여 양질의 보차도용 조립식 블록을 제조하는 방법을 제공코저 한다.Accordingly, the present invention provides a method for manufacturing a high quality sidewalk prefabricated block by recycling waste refractories, waste tiles, and waste ceramics classified as industrial waste.
이를 위하여 본 발명은, 폐내화물과 폐타일 그리고 폐도자기를 3대의 조-크라샤로 각기 별도로 투입시켜 입자의 직경이 3∼4mm 이내가 되도록 분쇄시키는 제1공정과; 상기 제1공정을 거친 3종류의 원료분말들이 원료분말 전체중량 대비 각기 1/3의 비율로 섞이도록 믹서기를 통해 교반시키는 제2공정과; 상기 제2공정이 종료된 후 카올린을 상기 원료분말 전체중량 대비 10%를 투입시킴과 동시에 유해물질이 함유되어 있지 않은 물을 상기 원료분말 전체중량 대비 5%를 투입시켜 동시 교반시키는 제3공정과; 상기 제3공정을 거친 원료분말에 수용성 CMC 분말접착제를 원료분말 전체중량 대비 4∼5%를 투입시켜 교반시키는 제4공정과; 상기 제4공정을 거친 원료분말을 프레스 몰드로 공급하여 기본 또는 이형치수의 형태로 포밍시키는 제5공정과; 상기 제5공정을 거쳐 완성된 반제품을 200℃의 열풍건조실로 이동시키는 제6공정과; 상기 제6공정을 거친 반제품의 일측 표면에 색상을 가진 유약을 도포하는 제7공정과; 상기 제7공정을 거친 반제품을 로 안으로 투입시켜 1,100∼1,200℃의 열을 가하면서 6시간 정도 소성시키는 제8공정과; 상기 제8공정을 거친 완성품을 대기중에서 냉각시키는 제9공정으로 구성됨을 특징으로 한다.To this end, the present invention comprises the first step of separately crushing the waste refractory, waste tiles and waste ceramics into three co-crushers so that the diameter of the particles within 3 ~ 4mm; A second step of stirring through a mixer to mix the three types of raw material powders passed through the first step at a ratio of 1/3 of the total weight of the raw material powders; After the second step is finished and the kaolin is added to 10% of the total weight of the raw material powder and at the same time 5% of the total weight of the raw material powder containing water containing no harmful substances and simultaneously stirred and ; A fourth step of adding 4-5% of the water-soluble CMC powder adhesive to the total weight of the raw material powder and stirring the raw material powder after the third step; A fifth step of supplying the raw material powder, which has passed through the fourth step, to a press mold to form a basic or release dimension; A sixth step of moving the semi-finished product completed through the fifth step to a hot air drying chamber at 200 ° C .; A seventh step of applying a glaze having color to one surface of the semi-finished product having passed through the sixth step; An eighth step of firing the semi-finished product having passed through the seventh step into a furnace and baking for about 6 hours while applying heat at 1,100 to 1,200 ° C .; And a ninth step of cooling the finished product after the eighth step in the air.
이하 본 발명의 바람직한 일실시예에 따른 세라믹소재 보차도용 조립식 블록의 제조방법을 상세히 설명한다.Hereinafter, a method of manufacturing a prefabricated block for ceramic material sidewalks according to a preferred embodiment of the present invention will be described in detail.
폐내화물과 폐타일 그리고 폐도자기를 3대의 조-크라샤로 각기 별도로 투입시켜 입자의 직경이 3∼4mm 이내가 되도록 분쇄시키는 제1공정에 있어서; 폐내화물과 폐타일, 폐도자기를 수거한 후 빗물이나 수분이 침투하지 못하도록 각기 별도로 보관하였다가 각각 조-크라샤를 통해 분쇄시키는데, 분쇄된 입자의 직경은 3∼4mm 이내가 되도록 한다. 이때 입자의 직경이 4mm를 초과하는 것은 다시 수거하여 조-크라샤를 통해 상기 범위의 이내로 재분쇄시키고 입자의 직경이 3mm 이하인 분말은 별도로 수거하여 바람직한 방법을 통해 처리한다.In a first step of pulverizing waste refractories, waste tiles, and waste ceramics into three co-crushers separately so that the diameter of the particles is within 3 to 4 mm; After collecting waste refractories, waste tiles, and waste ceramics, each is separately stored to prevent rainwater or moisture from penetrating, and then pulverized through a crude crusher. The diameter of the pulverized particles is within 3 to 4 mm. At this time, the diameter of the particles exceeding 4mm is collected again and re-crushed within the above range through the co-crusher, and the powder having a diameter of 3mm or less is collected separately and treated through a preferred method.
다음, 상기 제1공정을 거친 3종류의 원료분말들이 원료분말 전체중량 대비 각기 1/3의 비율로 섞이도록 믹서기를 통해 3톤 정량, 30분 정도 교반시키는 제2공정을 실시하였다.Next, a third process was performed in which the three kinds of raw material powders passed through the first process were mixed at a ratio of 3 tons and stirred for about 30 minutes to be mixed at a ratio of 1/3 of the total weight of the raw material powders.
다음, 상기 제2공정이 종료된 후 카올린(고령토)을 상기 원료분말 전체중량 대비 10%를 투입시킴과 동시에 유해물질이 함유되지 않은 물을 상기 원료분말 전체중량 대비 5% 투입시켜 동시 교반시키는 제3공정에 있어서; 상기 카올린 분말의 입자직경은 3∼4mm이고 점토질의 함량은 90% 정도인 것을 사용하였고 교반시간은 20분 정도를 소요하였다. 이때 상기 카올린은 화학적분리와 타화합물로의 전환이용하여 응집력을 가질 수 있는 용도로서 사용된다.Next, after the second process is finished, the kaolin (kaolin) is added to 10% of the total weight of the raw material powder and at the same time water containing no harmful substances 5% of the total weight of the raw material powder to simultaneously stir In 3 steps; The particle diameter of the kaolin powder was used 3 to 4mm and the content of clay is about 90% and the stirring time required about 20 minutes. At this time, the kaolin is used as a use that can have a cohesive force by using the chemical separation and conversion to other compounds.
다음, 상기 제3공정을 거친 원료분말에 수용성 CMC(carboxy methyl cettulose) 분말접착제를 원료분말 전체중량 대비 4∼5%를 투입시켜 교반시키는 제4공정을 실시하였다. 이때 교반시간은 10∼15분을 소요하였다.Next, a fourth step of adding a water-soluble CMC (carboxy methyl cettulose) powder adhesive to 4-5% of the total weight of the raw material powder was carried out to the raw material powder after the third step. At this time, the stirring time was 10 to 15 minutes.
다음, 상기 제4공정을 거친 원료분말을 프레스 몰드로 공급하여 기본 또는 이형치수 형태로 포밍시키는 제5공정에 있어서; 상기 프레스 몰드는 소정의 두께를 가지는 블록을 생산할 수 있는 직사각형 또는 정사각형의 금형을 사용하였다. 일단, 가로×세로=228mm×114mm이고 두께는 60mm인 블록을 생산하기 위해 상기 금형의 안으로 2Kg의 원료분말을 투입시켰다. 이때 투입되는 원료분말의 량이 2Kg이하일 경우에는 원료분말들의 입자 밀도가 조밀하지 못하여 블록의 강도가 저하됨을 알 수 있었다. 반면, 투입되는 원료분말의 량이 2Kg을 초과할 경우에는 블록의 강도는 향상되지만 자체중량이 너무 무거워지고 이에 따라 불필요한 재료의 소모로 인해 비경제적이라는 결론이 산출되었다.Next, in the fifth step of supplying the raw material powder subjected to the fourth step to the press mold to form a basic or mold release dimension; The press mold used a rectangular or square mold capable of producing a block having a predetermined thickness. First, 2Kg of raw powder was introduced into the mold to produce a block having a width x length = 228 mm x 114 mm and a thickness of 60 mm. In this case, when the amount of the input powder is 2Kg or less, the particle density of the raw powder was not dense and the strength of the block was reduced. On the other hand, when the amount of raw material powder added exceeds 2Kg, the strength of the block is improved but its own weight is too heavy, and accordingly, it is concluded that it is uneconomical due to the consumption of unnecessary materials.
다음, 상기 제5공정을 거쳐 완성된 반제품을 건조실로 이동시켜 200℃의 열풍을 가하면서 강제로 건조시키는 제6공정을 실시하였다.Next, the sixth step of moving the semi-finished product completed through the fifth step to the drying chamber and forcibly drying while applying hot air at 200 ° C. was performed.
다음, 상기 제6공정을 거친 완제품의 일측 표면에 유약을 도포시키는 제7공정을 실시함에 있어서; 유약의 색상 및 종류는 1) Ti-Yellow(Ti-Cr-Sb), Mn-Pink(Al-Mn), Al-Green(Al-Cr), Co-Blue(Al-Co) 등을 사용하였다. 상기 유약을 반제품의 일측 표면에 도포시키는 방법으로서는, 체인컨베어 위에서 적정한 간격을 유지한 채 상기 반제품이 얹히도록 한 후 상기 체인컨베어를 일방향으로 이동시킨다. 이때 상기 체인컨베어의 하방에는 유약통이 위치토록 함으로써 반제품의 저면이 유약에 닿도록 하였다. 이때 상기 반제품은 유약에 반침전되도록 하였다.Next, in the seventh step of applying a glaze on one surface of the finished product after the sixth step; The color and type of glaze were 1) Ti-Yellow (Ti-Cr-Sb), Mn-Pink (Al-Mn), Al-Green (Al-Cr), Co-Blue (Al-Co) and the like. As a method of applying the glaze on one surface of the semifinished product, the semi-finished product is placed on the chain conveyor while maintaining an appropriate interval, and then the chain conveyor is moved in one direction. At this time, the bottom side of the semi-finished product was in contact with the glaze by allowing the glaze container to be positioned below the chain conveyor. At this time, the semi-finished product was to be semi-precipitated in the glaze.
상기 제7공정이 종료된 후 유약이 도포된 면이 위를 향하도록 하여 로 안으로 투입되도록 하고 1,100∼1,200℃의 열을 가하면서 6시간 정도 소성시키는 제8공정을 가하여 완성시켰다. 그 이후 상기 제8공정을 거친 완성품을 대기중에서 냉각시키는 제9공정을 최종적으로 행하였다.After the seventh step was completed, the glaze-coated surface was turned upward to be introduced into the furnace, followed by an eighth step of firing for about 6 hours while applying heat at 1,100 to 1,200 ° C., thereby completing the eighth step. Thereafter, a ninth step of finally cooling the finished product after the eighth step in the air was finally performed.
한편, 본 발명의 제조공정에서 분쇄, 정확한 입도관리, 진동주입성형 그리고 특히 중요한 것은 소성이다. 소성은 다음과 같은 두가지 중요한 목적이 있다. 첫째는 원료를 소성처리하여 열화학적 변화를 일으켜 줌으로써 미리 안정된 화학조성 및 광물상으로 하는 것이며, 둘째는 이와 같이 안정화된 원료를 고온처리로 소결시켜 필요한 형상과 결합조직을 갖게 하는 것이다. 따라서 이 목적을 달성하기 위한 소성처리는 개개의 원료 종류에 따라서 다르며, 일률적이 아니나 그 처리의 근거는 광물성질의 결정화학적 지식과 제품의 구성적 문제에 입각한 것이다.On the other hand, in the manufacturing process of the present invention, grinding, accurate particle size control, vibration injection molding, and particularly important are firing. Firing has two important purposes: First, the raw material is calcined to produce a thermochemical change, so that the chemical composition and mineral phase are stabilized in advance. Second, the stabilized raw material is sintered by high temperature treatment to have the required shape and connective structure. Therefore, the firing treatment to achieve this purpose varies depending on the type of raw materials, and is not uniform, but the basis of the treatment is based on the crystallographic knowledge of the mineral properties and the compositional problems of the product.
본 발명의 제조방법에 의해 생산된 블록은 유약이 처리된 표면은 마치 도자기류와 같이 매우 매끈함은 물론 색상의 표출상태 또한 은은하고 미려하였다.The block produced by the manufacturing method of the present invention, the surface treated with glaze was very smooth as well as porcelain, as well as the appearance of the color was subtle and beautiful.
또한 그 외관에 있어서 겉모양이 균일하고 비틀림이나 균열, 얼룩, 깨진 곳 또는 흠이 없어 KS 규격상 하자가 없었다.In addition, the external appearance was uniform in appearance, and there were no torsion, cracks, stains, cracks or scratches, so there was no defect in the KS standard.
그리고 시편을 24시간 동안 물속에 담근 후 꺼낸 즉시 휨강도를 검사하였다. 시료의 양측 저면에 받침물을 고이고 양측 받침물의 중앙에 누름하중을 가하여 하기의 (식)에 따라 휨강도를 측정하였다.The specimens were immersed in water for 24 hours and immediately tested for flexural strength. The support was placed on the bottom of both sides of the sample, and a pressing load was applied to the center of both of the bases, and the bending strength was measured according to the following equation.
여기서 P는 시험기가 나타낸 최대하중(N){Kgf}이고, L은 지점간(받침물 사이)의 거리(cm)이며 b는 상기 지점간에 직각 방향의 평균너비(cm)이며 d는 블록의 평균 두계(cm)이다.Where P is the maximum load (N) {Kgf} indicated by the tester, L is the distance (cm) between points (between supports), b is the average width (cm) at right angles between the points and d is the average of the blocks It is head (cm).
한편, KS 규격에 근거하면 보도용 블록은 휨강도가 최소 490N/cm2{50Kgf/cm2}이어야 하고 차도용 블록은 최소 588N/cm2{60Kgf/cm2}이어야 하는데, 본 발명의 블록은 588N/cm2{60Kgf/cm2}의 수치를 충분히 만족함을 알 수 있었다.On the other hand, based on the KS standard, the sidewalk block should have a flexural strength of at least 490N / cm 2 {50Kgf / cm 2 } and the driveway block should be at least 588N / cm 2 {60Kgf / cm 2 }. It was found that the value of / cm 2 {60Kgf / cm 2 } was sufficiently satisfied.
