폐 섬유유리를 이용한 연돌 라이너용 발포유리블럭의 제조방법 {Method Preparation of Chimney Liner Foamed Glass Block use of Waste Fiber Glass}Method for manufacturing foam glass block for stack liner using waste fiber glass {Method Preparation of Chimney Liner Foamed Glass Block use of Waste Fiber Glass}

본 발명은 발전소의 연돌 내부에 설치하여 라이너로 사용되어지는 발포유리블럭의 제조방법에 관한 것이다. The present invention relates to a method of manufacturing a foamed glass block which is installed inside a duct of a power plant and used as a liner.

더욱 상세하게는 주원료인 폐 섬유유리에 적정량씩의 산화규소(SiO2), 붕산화수소(H3BO3), 황산나트륨(Na2SO4) , 삼산화이철(Fe2O3)을 첨가하여 용융하고 냉각시킨 후에 분쇄하여 원료분말을 얻고, 이와 같이 얻어진 원료분말에 적정량의 탄소를 첨가 혼합하여 고온으로 유지되는 소성로에서 일정한 시간동안 소성 한 후에 이를 서서히 냉각시키고 안정화시켜 독립기포(폐기공)가 균일하게 형성되어지도록 함으로써, 화학적 내구성이 양호하고 흡수성이 적으며, 단열보온성과 내열성 및 전기절연성이 우수한 폐 섬유유리를 이용한 연돌 라이너용 발포유리블럭의 제조방법을 제공하려는 것이다. More specifically, silicon oxide (SiO 2 ), hydrogen borate (H 3 BO 3 ), sodium sulfate (Na 2 SO 4 ), and ferric trioxide (Fe 2 O 3 ) in an appropriate amount are added to the waste fiberglass, which is the main raw material, and melted. After cooling, it is pulverized to obtain a raw material powder. The raw material powder thus obtained is mixed with an appropriate amount of carbon and calcined for a predetermined time in a kiln maintained at high temperature, and then gradually cooled and stabilized to uniformly separate the bubbles (waste pores). It is intended to provide a method for producing a foamed glass block for a stack liner using waste fiber glass having good chemical durability, low water absorption, and excellent heat insulation and heat resistance and electrical insulation.

발전소에 설치되는 연돌은 탈황설비를 설치하기 전의 배기가스온도가 125 ~180℃이므로 내열성이 강한 내화물을 필요로 하였으나, 탈황설비를 설치한 후에는 탈황설비를 통과한 직후의 배기가스 온도가 약 85 ~ 90℃가 되므로 내산성과 내수성이 강한 내화물을 필요로 하게 된다. Since the flue gas temperature before installation of desulfurization equipment is 125 ~ 180 ℃, it is necessary to use refractory materials that have high heat resistance.However, after the desulfurization equipment is installed, the exhaust gas after passing through the desulfurization equipment is about 85 ° C. Since the temperature of ~ 90 ° C is high, refractory materials with strong acid resistance and water resistance are required.

그런데, 기존 연돌 구조물의 코오벨지지 내산,내열벽돌 라이너(Liner)는 연돌 구조물의 온도가 균일하지 못하였고, 코오벨 간격의 부적합 등으로 인하여 라이너에 균열이 발생될 뿐만 아니라 그로 인하여 라이너가 부분적으로 손상되어 단열효과가 저하되면서 콘크리트에 균열이 발생하며, 콘크리트 내부 측에는 아황산가스에 의한 중화성 및 열화현상이 발생하여 단면손실이 일어나게 되고 그로 인하여 구조물의 수명을 단축시키는 문제가 있었다. However, the liner of acid-resistant and heat-resistant brick liners of existing masonry structures are not uniform in temperature of the masonry structures, and the liner is partially cracked due to inadequate cracking in the liner due to inadequate co-belt spacing. There was a problem of cracking in the concrete due to damage and a decrease in the thermal insulation effect.Inside of the concrete, neutralization and deterioration caused by sulfurous acid gas occurred, resulting in cross-sectional loss and thereby shortening the life of the structure.

또한 강재연통 케스타블 몰타르(Castable Mortar)는 칼슘알루미나계 등을 사용하였으나 일반적으로 10년 이상이 되면 내산성이 급격하게 저하하게 되고, 삼산화이철(Fe2O3)의 성분이 2 ~ 12% 정도 증가하여 강재연통을 부식시키는 문제가 있다.  따라서 탈황설비를 설치할 때에는 연돌구조물의 내부 보강공사를 필연적으로 설치해 주어야 한다. In addition, steel communication castable mortar (Castable Mortar) used calcium alumina, etc., but in general, the acid resistance is sharply lowered after more than 10 years, the composition of the ferric trioxide (Fe 2 O 3 ) is about 2 ~ 12% Increasingly, there is a problem of corroding steel communication. Therefore, when installing desulfurization equipment, internal reinforcement work of stack structure is inevitably required.

따라서 상기와 같은 문제를 해소할 수 있도록 하기 위한 최적의 공법으로는 발포유리블럭 라이너(Liner)로 시공해 주는 것이 가장 바람직하다. Therefore, the best method for solving the above problems is to use a foamed glass block liner.

이러한 발포유리블럭 라이너(Liner)는 첫째 발포유리블럭 자체가 불투성이므로 아황산배기가스가 침투하지 않게 되고, 둘째 발포유리블럭의 재질의 주성분이 유리이므로 아황산가스와 반응하지 않아 블럭이 부식되지 않게 되며, 셋째 블럭과 블럭 사이가 탄성재질의 접착제로 충진되어 있고 발포성 유리블럭의 열전도율이 다른 재료들 보다 매우 낮아 온도가 심한 곳에 사용할 수 있는 장점을 갖고 있다. Since the first foamed glass block itself is impermeable, the sulfurous acid exhaust gas does not penetrate into the foamed glass block liner, and the second component of the foamed glass block is glass, which does not react with sulfurous acid gas and does not corrode. In addition, the third block and the block are filled with an elastic adhesive and the foamable glass block has a lower thermal conductivity than other materials, which has the advantage of being able to be used in places where the temperature is severe.

특히, 상기의 발포유리는 일명 다포(多泡)유리 및 다포초자(硝子) 그리고 Foam Glass 및 Multicelluar Glass라고도 일컬어지는 것으로서, 독립기포(폐기공)조직을 갖고 있고, 유리자체의 독립기포 조직에서 기인하는 물성에 의해 단열성, 가공성, 흡수성, 내화학성, 경량성 등의 특성을 갖고 있는 유리이며, 단열성이 우수하므로 석유화학공정, LNG탱크의 바닥단열, 냉동창고, 발전소 연돌 내부 라이너 등으로 널리 사용되고 있을 뿐만 아니라 건축용 단열재 등으로 널리 이용될 전망이다. In particular, the above-described foamed glass, also known as polyporous glass and polypocoza, and also known as foam, glass, and multicelluar glass, have an independent bubble (waste-pore) tissue and are independent of the glass itself. It is a glass that has characteristics such as heat insulation, processability, water absorption, chemical resistance, and light weight due to its physical properties, and because of its excellent heat insulation performance, it is widely used in petrochemical processes, floor insulation of LNG tanks, refrigerated warehouses, internal power lines, power line, and so on. Not only that, it is a prospect that will be widely used for building insulation materials.

발포유리의 제조는 프랑스의 St. Gobain사의 특허와 동사의 B. Long이 그 시초로서 유리분말에 침강성 탄산칼슘을 혼합하여 용기에 담고, 고온에서 가열 발포시킨 다음 서서히 냉각시키는 방법에 의해 제조하였었다. 그러나 이와 같은 방법에 의해 제조된 발포유리는 기공이 불균일하여 단열재보다 콘크리트에 혼합하여 주로 경량골재로 사용하였었다. Manufacturing of foamed glass is carried out in France. Gobain's patent and B.Long's patents were prepared by mixing sedimentary calcium carbonate in glass powder, placing it in a container, heating it at high temperature, and then cooling it slowly. However, foamed glass manufactured by the same method was used as a light aggregate, mainly mixed with concrete rather than heat insulating material due to uneven pores.

1940년대에는 Pittsburgh Corning사에서 탄소를 발포로 하는 제조방법이 개발되었으며, 이는 현재까지도 단열재 및 보냉재로 사용되고 있다. In the 1940's, Pittsburgh Corning Corporation developed a process for carbon-to-foaming, which is still used today as insulation and coolant.

또 일본(공개특허)에서는 알칼리용액에 의해 유리를 가수분해 시켜 반응에 관여한 수분을 발포공정에서 기화시켜 줌으로써 겉보기 비중이 0.4 ~ 0.5인 발포유리를 제조하였으나, 상품성을 갖는 발포유리 즉 발포유리의 밀도가 0.3g/㎤를 갖는 발포유리의 제조가 불가능하였다. In Japan (open patent), the glass is hydrolyzed by alkaline solution to vaporize the moisture involved in the reaction in the foaming process, producing a foam glass with a specific gravity of 0.4 to 0.5. Manufacturing of foamed glass having a density of 0.3 g / cm 3 was impossible.

그리고 1956년에는 5 ~ 50wt%의 탄소를 함유하고 10㎡/g의 표면적을 갖는 실리카(Silica) 또는 규조토와 같은 물질로 형성된 폐 유리에 0.08 ~ 0.15wt%의 카본블랙을 가하여 일정한 온도에서 유리를 연화 및 발포시키고 냉각 및 서냉시켜 발포유리를 제조하는 방법을 제안하였었다. 이는 탄소와 Arsenic, Stibium, Vanadium, Molibdene, Tungsten 등의 산화-환원반응에 의해 기체가 생성되는 것을 이용하고 있으나, 산화제가 SO3(또는 SO2)을 방출시켜 주도록 하는 방법은 낮은 밀도를 갖는 양질의 발포유리를 제조하기에는 적합하지 못하였다. In 1956, 0.08 to 0.15 wt% of carbon black was added to waste glass formed of a material such as silica or diatomaceous earth, containing 5 to 50 wt% of carbon and having a surface area of 10 m2 / g. It has been proposed a method of producing foamed glass by softening and foaming, cooling and slow cooling. Gas is generated by redox reactions such as carbon, Arsenic, Stibium, Vanadium, Molibdene, Tungsten, etc., but the method of allowing the oxidant to release SO 3 (or SO 2 ) is high quality with low density. It was not suitable for producing foamed glass of.

또한 발포유리의 특성에 관한 연구는 1965년 Walsh, Brace 등이 기공율과 유리의 압축강도에 관한 Mackenzie의 식을 변경하여 다양한 기공을 가지는 유리에 적용할 수 있는 식을 구하였고, 1982년 Low는 glass-mica composite solid의 제조에 있어 재활용된 soda-lime waste glass의 분말과 phlogopite형의 천연 mica 분말을 혼합하기 전에 열처리를 통해서 mica 구조의 내부에 존재하는 수분을 제거한 상태에서 혼합시료를 소성시키면 cellular structure의 현상이 억제되며 이는 mica 분말의 열적 탈수정도에 따라 달라진다고 하였으며, 1991년 일본의 Central Glass사는 40㎛의 직경을 갖는 실리카 유리분말에 동일한 입경을 가진 Sr-carbonate를 1 ~ 5%정도 혼합하여 실리카유리의 점도가 107.65 ~ 106poise이 되는 온도범위에서 0.5g/㎤의 밀도를 갖는 발포유리를 제조하였었다. In addition, in 1965, Walsh, Brace et al. Modified Mackenzie's equations for porosity and compressive strength of glass and applied them to glass with various pores. In the manufacture of mica composite solid, the mixed structure is fired by removing the water present inside the mica structure by heat treatment before mixing the recycled soda-lime waste glass powder with the phlogopite type natural mica powder. It is said that this phenomenon is dependent on the degree of thermal dehydration of mica powder.In 1991, Central Glass Co., Ltd., Japan, mixed 1 ~ 5% of Sr-carbonate with the same particle size in silica glass powder with 40㎛ diameter. A foamed glass having a density of 0.5 g / cm 3 was prepared in a temperature range in which the viscosity of the glass was 10 7.65 to 10 6 poise.

특히, 우리나라에서는 1976년경에 다량의 수분이 함유된 K.F. Glass의 cullet를 원료로 하고 발포제로는 탄산칼슘계통의 석탄석을 사용하여 발포유리의 제조공정과 물성을 연구하였었고, 1978년경에는 slag-glass를 이용하는 form glass에 관한 연구를 하였으며, 1996년경에는 유리분말의 직접발포에 의한 발포유리블럭의 생산방법에 대하여 제안하였는데, 이는 분쇄된 유리에 다량의 CaCO3 또는 CaSO4 등의 발포제를 첨가하여 혼합하고 이를 형틀에 충진하여 예열 및 소성하며 이때에 생성되는 SOX 또는 COX에 의해서 발포유리를 제조하도록 하는 방법으로써, 알칼리를 사용하지 않고 가압 하에서 단지 수분만을 사용한 가수분해 반응을 거친 유리를 사용하여 발포공정을 통해 제조되는 발포유리이므로 균일한 기공직경을 지닌 경량의 낮은 열전도도를 지닌 양질의 발포유리를 제조할 수 있었다. In particular, in 1976, KF Glass cullet containing a large amount of water was used as a raw material and calcium carbonate coal was used as a blowing agent, and the manufacturing process and physical properties of foam glass were studied around 1978. A study on form glass using glass was proposed. In 1996, a method of producing foamed glass blocks by direct foaming of glass powder was proposed, which was obtained by adding a large amount of blowing agent such as CaCO 3 or CaSO 4 to the ground glass. Mixing, filling it into a mold, preheating and firing, and producing a foamed glass by SO X or CO X produced at this time, using a glass that has undergone hydrolysis using only moisture under pressure without using alkali. Is a foamed glass manufactured through the foaming process, so it has a high quality foam with light weight and low thermal conductivity with uniform pore diameter. Glass could be prepared.

상기와 같은 발포유리를 이용한 발포유리블럭을 제조하는 방법으로는 용융공법, 소결공법(직접발포), 가수분해공법이 알려져 있다. As a method of manufacturing a foamed glass block using such a foamed glass, there are known a melt melting method, a sintering method (direct foaming), and a hydrolysis method.

소결공법(직접발포)은 별도의 전처리 과정 없이 유리를 직접 분쇄하여 발포유리블럭을 제조하는 방법으로 별도의 전처리 과정 없이 직접 발포를 하기 때문에 생산제조원가를 절감할 수 있는 장점은 가지고 있다. 그렇지만 용융공법에 비해서 발포유리블럭을 제조하였을 경우에 발포유리블럭의 물리적인 특성인 열전도도, 선열팽창계수 등이 다소 떨어지는 단점을 가지고 있어 연돌의 내부 라이너로 사용되어지는 발포유리블럭의 제조방법에는 소결공법이 적합하지 않다. The sintering method (direct foaming) is a method of manufacturing glass foam by directly grinding the glass without a separate pretreatment process, and thus has the advantage of reducing the manufacturing cost by directly producing the foam without a separate pretreatment process. However, when manufacturing foamed glass blocks compared to the melting method, the physical properties of the foamed glass blocks have some disadvantages, such as thermal conductivity and linear thermal expansion coefficient, which are used in the production of foamed glass blocks used as inner liner of the stack. The sintering method is not suitable.

가수분해공법은 분쇄된 유리분말과 물을 고온 고압의 autoclave에서 반응시켜 얻어진 원료를 이용하여 발포유리블럭을 제조하기 위한 출발원료를 얻는 방법으로써, 별도의 고온 고압 상태의 autoclave가 필요하고, 출발원료 물질에 함유된 많은 수분의 양을 건조시키기 위해서 별도의 건조장치를 설비하여야 한다. The hydrolysis method is a method of obtaining starting materials for producing foamed glass blocks using raw materials obtained by reacting crushed glass powder and water in a high-temperature, high-pressure autoclave, which requires a separate autoclave of high temperature and high pressure. A separate drying unit must be installed to dry the large amounts of moisture in the material.

용융공법은 발포유리블럭을 제조하기 위해서 원료 유리조성을 넣고 유리를 녹여서 발포유리블럭을 제조하기 위한 출발원료를 얻는 방법으로 용융시에 생산원가를 다소 증가시키기는 하나 안정적인 특성을 갖는 발포유리블럭을 제조할 수 있다. Melting process is a method of manufacturing raw foam glass blocks to manufacture foamed glass blocks and melting the glass to obtain starting materials for manufacturing foamed glass blocks, which increases production costs in melting, but produces stable foam blocks with stable characteristics. can do.

용융공법을 사용한 종래의 발포유리조성물 및 그 제조방법으로는 특허출원 제1999-76196호 　단열재용 발포유리 조성 및 그 제조방법　이 알려져 있다. 그러나 이는 통상의 발포유리단열재를 그 원료유리의 조성인 소다-석회의 유리조성의 기본으로 하고 저팽성 발포유리의 특성을 갖는 B2O3성분을 다량 첨가하여 용융한 출발원료 유리를 얻은 것으로, 발포유리블럭을 제조하였을 경우 압축강도, 휨강도 등의 특성치는 우수하게 나타나 건축용(단열재용)으로는 적합하지만, 열전도도, 선열팽창계수의 물성치가 연돌 내부 라이너의 사용기준에 도달하지 않아 건축용을 제외한 발전소 연돌용으로 사용하기에는 적합하지 못한 문제점이 있었다. As a conventional foamed glass composition using a melting method and a method for producing the same, a foamed glass composition for heat insulating material and a method for manufacturing the same are known. However, this is obtained from the starting glass of the molten glass obtained by adding a large amount of B 2 O 3 component having a characteristic of low-expansion foamed glass as the basis of the glass composition of soda-lime, which is the composition of the raw material glass, When foamed glass blocks are manufactured, the characteristics such as compressive strength and flexural strength are excellent, which makes them suitable for building use (insulation material) .However, the thermal conductivity and coefficient of thermal expansion coefficient did not reach the standard of use of internal liner, except for building use. There was a problem that is not suitable for use in power plant stacks.

이러한 문제점을 해결하기 위해, 일반적으로 발전소 연돌용으로 사용하는 발포유리블럭은 고가의 산화붕소(B2O3)를 다량 첨가하게 되므로 제조원가가 상승하는 문제가 있었다. In order to solve this problem, foam glass blocks generally used for power plant stacks have a problem in that the production cost increases because a large amount of expensive boron oxide (B 2 O 3 ) is added.

본 발명은 상기와 같은 문제를 해소 할 수 있도록 된 폐 섬유유리를 이용한 연돌 라이너용 발포유리블럭의 제조방법을 제공하려는 것이다. The present invention seeks to provide a method for manufacturing foamed glass blocks for masonry liners using closed fiberglass, which is designed to solve the above problems.

본 발명은 주원료인 폐 섬유유리 분말에 산화규소(SiO2), 붕산화수소(H3BO3), 황산나트륨(Na2SO4), 삼산화이철(Fe2O3)을 적정량씩 첨가 혼합하여 용융시키고, 이를 분쇄하여 원료분말을 얻으며, 이와 같이 얻어진 원료분말에 발포보조제인 탄소(Lonza KS-6, KJ-Block)를 적정량 첨가 혼합하고 고온으로 유지되는 소성로에서 일정한 시간동안 소성 한 후에 서서히 냉각시켜서 제조된 폐 섬유유리를 이용한 연돌 라이너용 발포유리블럭의 제조방법을 제공하려는데 그 목적이 있다. The present invention is melted by adding and mixing the appropriate amount of silicon oxide (SiO 2 ), hydrogen borate (H 3 BO 3 ), sodium sulfate (Na 2 SO 4 ), ferric trioxide (Fe 2 O 3 ) to waste fiber glass powder as a main raw material , To obtain a raw powder by pulverizing it, and by adding an appropriate amount of carbon (Lonza KS-6, KJ-Block) as a foaming aid to the raw powder obtained in this way, and then by sintering in a kiln maintained at high temperature for a certain time, slowly cooling It is an object of the present invention to provide a method for producing a foamed glass block for stack liner using waste fiber glass.

상기 소성은 550 ~ 750℃(+5~+30℃/min)에서 바람직하게는 600 ~ 650℃(+5~+30℃/min)에서 서서히 예열하고, 550~1100℃(+6~+15℃/min)온도에서 바람직하게는 600~1000℃(+6~+15℃/min)온도에서 성형한 후, 900~1100℃에서 바람직하게는 950~1050℃에서 10 ~ 30분간 유지시켜 주고, 서냉은, 발포된 발포유리를 1100~550℃(-3~-10℃/min)에서 바람직하게는 1000~600℃(-3~-10℃/min)에서 안정화시킨후에 650~200℃(-5~-20℃/min)로 바람직하게는 600~250℃(-5~-20℃/min)로 급냉시키고 300~50℃(-1~-3℃/min)를 바람직하게는 250~80℃(-1~-3℃/min)를 유지시켜 준다.The firing is preheated slowly at 550 ° C-750 ° C (+5-+30 ° C / min), preferably at 600 ° C-650 ° C (+5-+30 ° C / min), and then at 550-1100 ° C (+6-+15 ℃ / min), preferably at 600 ~ 1000 ℃ (+ 6 ~ + 15 ℃ / min) temperature, and then at 900 ~ 1100 ℃, preferably at 950 ~ 1050 ℃ for 10 ~ 30 minutes, Slow cooling stabilizes the foamed glass at 1100 to 550 ° C (-3 to -10 ° C / min), preferably at 1000 to 600 ° C (-3 to -10 ° C / min) and then at 650 to 200 ° C (- 5 to -20 ° C / min, preferably quenched to 600 to 250 ° C (-5 to -20 ° C / min), and 300 to 50 ° C (-1 to -3 ° C / min), preferably 250 to 80 ° C. ℃ (-1 ~ -3 ℃ / min) is maintained.

본 발명에 첨가되는 각 성분의 유리 구조내의 역할 및 유리 물성에 미치는 영향을 설명하면 다음과 같다. 산화규소(SiO2)는 유리의 망목 구성성분으로서 유리 형성의 기본 물질이며, 붕산화수소(H3BO3)는 용융점 온도 및 점도곡선 둔감 작용을 하며, 황산나트륨(Na2SO4)는 용융점을 낮추는 역할, 삼산화이철(Fe2O3)은 발포시 산소를 공급하는 작용을 한다.Referring to the role of each component added to the present invention in the glass structure and the effect on the glass physical properties are as follows. Silicon oxide (SiO 2 ) is the netting component of glass and is the basic material for glass formation.Hydroborate (H 3 BO 3 ) acts as a melting point temperature and viscosity curve insensitive, and sodium sulfate (Na 2 SO 4 ) lowers the melting point. Role, ferric trioxide (Fe 2 O 3 ) acts to supply oxygen when foaming.

본 발명의 실시 예에서 사용된 섬유유리 원료의 성분을 표 1에 나타내었다.The components of the fiberglass raw materials used in the examples of the present invention are shown in Table 1.

상기 폐 섬유유리를 이용한 발포유리에 첨가되는 물질과 특성을 살펴보면 아래와 같다. The materials and properties added to the foamed glass using the waste fiber glass are as follows.

폐 섬유유리(E-Glass)는 불연성, 화학적 내구성, 내열성 및 단열보온성, 전기절연성이 우수하고, 흡수성은 낮다. 또한 폐 섬유유리를 발포유리블럭 제조에 사용할 경우 일반 소다-석회유리에 비해 물리적 특성이 월등히 뛰어나게 되어 연돌 내부 라이너 발포유리블럭을 제조하기에 적합하며, 폐 섬유유리를 활용하므로 기존의 폐기물 처리비용은 폐기물의 재활용이 될 뿐만 아니라, 원료구입비용이 절약된다. Waste glass fiber (E-Glass) has excellent non-combustibility, chemical durability, heat resistance and thermal insulation, electrical insulation, and low absorption. In addition, when the waste fiberglass is used for manufacturing foamed glass blocks, the physical properties are superior to that of ordinary soda-lime glass, which is suitable for manufacturing the inner liner and foamed glass blocks of the masonry, and the waste fiberglass is used to make the existing waste disposal cost. Not only will waste be recycled, but raw material purchase costs are saved.

또한, 폐 섬유유리를 첨가할 경우 섬유유리에 산화붕소(B2O3)가 7%이상 함유되어 있으므로, 고가의 산화붕소(B2O3)의 첨가량을 낮추어 주어 소량 첨가하여 원료의 비용을 절약할 수 있다. In addition, when waste fiber glass is added, boron oxide (B 2 O 3 ) is contained in the fiber glass 7% or more. Therefore, the amount of expensive boron oxide (B 2 O 3 ) is lowered and a small amount is added to reduce the cost of raw materials. You can save.

산화규소(SiO2)는 전체 중량의 45~52wt%를 첨가하며, 유리의 기본골격인 망목구조를 형성하여 유리를 안정화시켜 준다. Silicon oxide (SiO 2 ) adds 45 ~ 52wt% of the total weight and stabilizes the glass by forming the network structure, which is the basic skeleton of glass.

또한, 산화붕소(B2O3)도 망목구성 성분으로서 점도, 용융온도의 저하를 가져오며 열팽창계수를 낮춰주고, 화학적 내식성 및 내구성을 증대시키는 역할을 한다.In addition, boron oxide (B 2 O 3 ) also serves as a network component to reduce the viscosity, melting temperature, lower the coefficient of thermal expansion, and increase the chemical corrosion resistance and durability.

산화나트륨(Na2O)은 용융온도를 낮추는 용제로서 망목수식제 역할을 한다.Sodium oxide (Na 2 O) is a solvent for lowering the melting temperature and serves as a mesh tree formula.

        산화알루미늄(Al2O3)은 안정제 산화물의 일종으로서 상분리와 실투를 억제하며 또한 화학적 내구성을 증대시키는 역할을 한다.Aluminum oxide (Al 2 O 3 ) is a type of stabilizer oxide, which inhibits phase separation and loss of devitrification and also increases chemical durability.

        산화칼슘(CaO)와 산화마그네슘(MgO)는 공히 안정제 산화물로서 용융효과를 증대시키고 점도를 낮추고 실투를 억제하는 기능을 갖는다. Calcium oxide (CaO) and magnesium oxide (MgO) are both stabilizer oxides, which have the function of increasing the melting effect, lowering viscosity and suppressing devitrification.

        산화붕소(BaO)는 산화칼슘(CaO)와 같은 융제로 작용하는 성분이다. 이는 산소의 친화력이 다른 알칼리류 금속에 비해 낮으므로 붕규산 유리에서 상분리의 원인이 되는 산화칼슘(CaO)의 대체 산화물로서 사용된다. Boron oxide (BaO) is a component that acts as a fluxing agent such as calcium oxide (CaO). It is used as a substitute oxide of calcium oxide (CaO), which is a cause of phase separation in borosilicate glass, because its affinity for oxygen is lower than that of other alkali metals.

        산화칼륨(K2O)는 붕규산유리에서는 상분리 방지제로서 효과가 크고,산화나트륨(Na2O)과 함께 용융점도를 개선시키고 서냉온도를 낮추며 표면장력을 낮추는 기능을 한다. Potassium oxide (K 2 O) is effective as a phase separation inhibitor in borosilicate glass and, together with sodium oxide (Na 2 O), improves the melt viscosity, lowers the slow cooling temperature and lowers the surface tension.

본 발명에 따른 상기 및 기타목적은 다음의 실시 예에 의해 더욱 명확하게 이해할 수 있으며, 본 발명이 본 실시 예에 의해 한정되지 않음을 밝혀 둔다. The above and other purposes in accordance with the present invention may be more clearly understood by the following examples, and it is noted that the present invention is not limited by the present embodiments.

<실시 예 1> <Example 1>

위에 나타낸 섬유유리 조성 성분을 기준으로 하여 100mesh이하로 분쇄한 폐 섬유유리(E-Glass) 70wt%에 산화규소(SiO2) 15wt%, 붕산화 수소(H3BO3) 8wt%, 황산나트륨(Na2SO4) 5wt%, 삼산화철(Fe2O3) 2wt%를 정확하게 칭량하여 Ball-mill로 1시간가량 혼합한 후 백금도가니에 담아 전기로에 넣고 1300℃에서 가열 용융을 하여 발포유리블럭 제조를 위한 원료를 제조하였다. 첨가한 산화규소(SiO2)는 산화규소(SiO2)를, 산화붕소(B2O3) 는 붕산화수소(H3BO3)를, 산화나트륨(Na2O)은 황산나트륨(Na2SO4)로, 삼산화이철(Fe2O3)는 삼산화이철(Fe2O3)를 통해서 첨가하였다. 이 원료유리를 Ball-mill를 이용하여 200mesh이하의 유리분말로 만들었다. Based on the fiberglass composition shown above, 70wt% of waste fiberglass (E-Glass) crushed to 100mesh or less, 15wt% of silicon oxide (SiO 2 ), 8wt% of hydrogen borate (H 3 BO 3 ), sodium sulfate (Na 2 SO 4 ) 5wt%, 2wt% of ferric trioxide (Fe 2 O 3 ) accurately weighed and mixed in a ball-mill for about 1 hour, put it in a platinum crucible, put it in an electric furnace and heat-melt at 1300 ℃ to prepare foamed glass block. The raw material for was prepared. The added silicon oxide (SiO 2 ) is silicon oxide (SiO 2 ), boron oxide (B 2 O 3 ) is hydrogen boride (H 3 BO 3 ), and sodium oxide (Na 2 O) is sodium sulfate (Na 2 SO 4 ), Ferric trioxide (Fe 2 O 3 ) was added via ferric trioxide (Fe 2 O 3 ). This raw glass was made into glass powder of 200mesh or less using a ball mill.

이 유리분말 전체 중량에 탄소 0.3wt%를 균일하게 혼합하여 정육면체의 거푸집에 넣고, 500 ~ 750℃에서 서서히 예열한 다음 800℃에서 30분정도 유지하는 조건에서 발포시킨다. 발포공정 후에 만들어진 발포유리는 600℃ 전후에서 안정화시킨 후 80℃까지 소둔(annealing)과정을 거쳐 발포기공이 2~3mm정도의 균일한 독립기포(폐기공)를 갖는 발포유리블럭을 제조하게 되었다. The glass powder is mixed with 0.3 wt% of carbon to the total weight and placed in a cube of cubes, preheated slowly from 500 to 750 ° C, and then foamed under the conditions of 30 minutes at 800 ° C. After the foaming process, the foamed glass was stabilized at around 600 ° C and then annealed to 80 ° C to produce a foamed glass block having a uniform independent bubble (waste pore) of about 2-3 mm.

<실시 예2> <Example 2>

100mesh이하로 분쇄한 폐 섬유유리(E-Glass) 80wt%에 산화규소(SiO2) 10wt%, 붕산화수소(H3BO3) 5wt%, 황산나트륨(Na2SO4) 2.5wt%, 삼산화이철(Fe2O3) 2.5wt%를 정확하게 칭량하여 Ball-mill로 1시간가량 혼합한 후 백금도가니에 담아 전기로에 넣고 1350℃에서 가열 용융을 하여 발포유리블럭 제조를 위한 원료를 제조하였다. 이 원료유리를 Ball-mill를 이용하여 200mesh이하의 유리분말로 만들었다. 80wt% of waste fiber glass (E-Glass) crushed to 100mesh or less, 10wt% of silicon oxide (SiO 2 ), 5wt% of hydrogen borate (H 3 BO 3 ), 2.5wt% of sodium sulfate (Na 2 SO 4 ), ferric trioxide ( Fe 2 O 3 ) 2.5wt% was accurately weighed and mixed with a ball-mill for about 1 hour, put into a platinum crucible, and heated and melted at 1350 ° C. to prepare a raw material for producing a foamed glass block. This raw glass was made into glass powder of 200mesh or less using a ball mill.

이 유리분말 전체 중량에 탄소 0.5wt%를 균일하게 혼합하여 정육면체의 거푸집에 넣고, 500~750℃에서 서서히 예열한 다음 900℃에서 30분정도 유지하는 조건에서 발포시킨다. 발포공정 후의 공정은 실시 예 1과 같은 과정을 통해서 발포유리블럭을 제조하였다.  실시 예 1의 제조 조건과 비교해서 첨가제의 양이 감소하였다. 특히 용융점을 낮추는 역할을 하는 황산나트륨(Na2SO4)의 양이 절반으로 감소하여 용융온도가 50℃정도, 탄소의 양도 다소 상승하였으며, 발포온도도 100℃정도 상승함을 알 수 있었다. 그러나 실시 예 1의 발포유리블럭 표면의 균질한 독립기공과 별 차이가 없음을 확인할 수 있었다. 0.5 wt% of carbon is uniformly mixed with the total weight of the glass powder and placed in a cube form cube, preheated slowly at 500 to 750 ° C, and foamed under conditions maintained at 900 ° C for 30 minutes. Process after the foaming step was prepared through the same process as in Example 1 foamed glass block. The amount of the additive was reduced compared to the preparation conditions of Example 1. In particular, the amount of sodium sulfate (Na 2 SO 4 ) that serves to lower the melting point was reduced by half, the melting temperature is about 50 ℃, the amount of carbon also slightly increased, the foaming temperature was also increased about 100 ℃. However, it could be confirmed that there is no difference with the homogeneous independent pores on the surface of the foam glass block of Example 1.

<실시 예3> <Example 3>

100mesh이하로 분쇄한 폐 섬유유리(E-Glass) 85wt%에 산화규소(SiO2) 5wt%, 붕산화수소(H3BO3) 5wt%, 황산나트륨(Na2SO4) 3wt%, 산화비소(As2O3) 2wt%를 정확하게 칭량하여 Ball-mill로 1시간가량 혼합한 후 백금도가니에 담아 전기로에 넣고 1350℃에서 가열 용융을 하여 발포유리블럭 제조를 위한 원료를 제조하였다. 이 원료유리를 Ball-mill를 이용하여 200mesh이하의 유리분말로 만들었다. 이 유리분말 전체 중량에 탄소 0.5wt%를 균일하게 혼합하여 정육면체의 거푸집에 넣고, 500~750℃에서 서서히 예열한 다음 900℃에서 30분정도 유지하는 조건에서 발포시킨다. 발포공정 후의 공정은 실시 예 1과 같은 과정을 통해서 발포유리블럭을 제조하였다. 실시 예 2의 제조 조건과 비교해서 산화규소(SiO2)의 양을 약간 감소하였고, 황산나트륨(Na2SO4)는 약간 증가하여 하였으며, 산소공급성분으로 삼산화이철(Fe2O3)을 대신에 산화비소(As2O3)를 이용하였다. 그 결과 용융온도나 발포온도는 거의 변함이 없었다. 그러나 실시 예 2의 발포기공이 2mm정도로 균일하게 생성된 반면 본 실시 예에서는 3mm정도의 다소 발포기공이 크기 생성되었음을 확인 할 수 있었다. 따라서 산소공급성분은 산화비소(As2O3)나 삼산화이철(Fe2O3)을 사용해도 발포에는 커다란 영향을 주지 않음을 확인할 수 있었다. 그러나 생산단가를 절감하기 위해서는 삼산화이철(Fe2O3)을 산소공급원으로 사용하는 것이 적합하다. 85wt% of waste fiber glass (E-Glass) crushed to 100mesh or less, 5wt% of silicon oxide (SiO 2 ), 5wt% of hydrogen borate (H 3 BO 3 ), 3wt% of sodium sulfate (Na 2 SO 4 ), arsenic oxide (As) 2 O 3 ) Accurately weighed 2wt% and mixed with ball-mill for about 1 hour, put it in platinum crucible, put it in an electric furnace and heat-melt at 1350 ℃ to prepare raw material for foam glass block production. This raw glass was made into glass powder of 200mesh or less using a ball mill. 0.5 wt% of carbon is uniformly mixed with the total weight of the glass powder and placed in a cube form cube, preheated slowly at 500 to 750 ° C, and foamed under conditions maintained at 900 ° C for 30 minutes. Process after the foaming step was prepared through the same process as in Example 1 foamed glass block. Compared with the preparation conditions of Example 2, the amount of silicon oxide (SiO 2 ) was slightly decreased, sodium sulfate (Na 2 SO 4 ) was slightly increased, and instead of ferric trioxide (Fe 2 O 3 ) as an oxygen supply component, Arsenic oxide (As 2 O 3 ) was used. As a result, the melting temperature and the foaming temperature were almost unchanged. However, while the foamed pores of Example 2 were uniformly generated to about 2 mm, in the present embodiment, it could be confirmed that the foamed pores of about 3 mm were somewhat generated. Therefore, it was confirmed that the oxygen supply component does not have a significant effect on foaming even when using arsenic oxide (As 2 O 3 ) or ferric trioxide (Fe 2 O 3 ). However, in order to reduce production costs, it is appropriate to use ferric trioxide (Fe 2 O 3 ) as an oxygen source.
