Description
本發明是有關於一種建材，特別是指一種利用轉爐石製造之人造建材。The present invention relates to a building material, in particular to a man-made building material made of converter stone.
近年來，環保意識逐漸抬頭，配合政府「循環經濟」政策的鼓勵下，如何將工廠製造過程中所產生的廢棄物循環再利用，已是公司研究的一大課題。以煉鋼而言，除了提煉而出的鋼液，同時也會產生許多副產物，例如高爐石、脫硫石，以及轉爐石。其中，高爐石可以取代部分水泥，所以有市場販售價值；而轉爐石除了提煉為公共工程的鋪面使用外，過往也曾試著以轉爐石取代天然石材來製作人造建材。然而，為了去除鋼液中的雜質，常會加入過量的石灰，使得吹煉完成後，渣中的氧化鈣含量過高，而使轉爐石中殘存游離氧化鈣以及氧化鎂。這些化合物遇水會產生膨脹現象，若是作為建材使用，將嚴重影響房屋強度以及美觀，而不具使用價值。In recent years, the awareness of environmental protection has gradually risen, and with the encouragement of the government's "recycling economy" policy, how to recycle the waste generated in the manufacturing process of the factory has become a major subject of the company's research. In terms of steelmaking, in addition to the molten steel produced by the refining, many by-products such as blast furnace stone, desulfurized stone, and converter stone are also produced. Among them, blast furnace stone can replace part of cement, so it has a market price value; while converter stone is not only refined for paving use in public works, but in the past there have been attempts to replace natural stone with converter stone to make artificial building materials. However, in order to remove the impurities in the molten steel, excessive lime is often added, so that after the conversion is completed, the content of calcium oxide in the slag is too high, and free calcium oxide and magnesium oxide remain in the converter stone. These compounds will swell when exposed to water. If they are used as building materials, they will seriously affect the strength and appearance of the house, and have no value in use.
隨著資金、人力的投入，轉爐石的資源化用途得到長足的技術進步，藉由加入改質劑，來進行造渣反應並消除渣中的游離氧化鈣，即可永久消除轉爐石水化膨脹的問題，並使轉爐石體積永久安定化，而讓改質轉爐石成為一種體積安定的可靠工程材料。With the investment of capital and manpower, considerable technological progress has been made in the use of converter stone as a resource. By adding modifiers to carry out the slagging reaction and eliminate the free calcium oxide in the slag, the hydration expansion of the converter stone can be permanently eliminated. In addition, the volume of converter stone is permanently stabilized, and the modified converter stone becomes a reliable engineering material with stable volume.
因此，本發明之目的，即在提供一種利用改質轉爐石製造之人造建材。Therefore, the purpose of the present invention is to provide an artificial building material made of modified converter stone.
於是，本發明人造建材，以總重量為100wt%計，包含重量百分比為60~95wt%的改質轉爐石，及重量百分比為5~40wt%的樹脂膠結材。Therefore, the artificial building material of the present invention, based on the total weight of 100% by weight, contains 60 to 95% by weight of modified converter stone and 5 to 40% by weight of resin cementing material.
本發明之功效在於：藉由將轉爐石經由改質處理後形成改質轉爐石，改善轉爐石原有遇水會膨脹的特性，使得轉爐石體積永久安定化，藉此製造出體積穩定、物化性質安定，且確實能符合用於建築之標準的可靠人造建材。The effect of the present invention is: by modifying the converter stone to form a modified converter stone, the original property of the converter stone that it will expand when exposed to water is improved, so that the volume of the converter stone is permanently stabilized, thereby producing stable volume and physical and chemical properties. Reliable man-made building materials that are stable and can indeed meet the standards used in construction.
本發明人造建材之一實施例，以總重量為100wt%計，包含重量百分比為60~95wt%的改質轉爐石，及重量百分比為5~40wt%的樹脂膠結材。在本實施例中，以該改質轉爐石為95wt%，而該樹脂膠結材為5wt%為較佳比例而說明。An embodiment of the artificial building material of the present invention, based on a total weight of 100 wt%, includes a modified converter stone of 60 to 95 wt% and a resin cementing material of 5 to 40 wt%. In this embodiment, the preferred ratio is that the modified converter stone is 95% by weight and the resin cement is 5% by weight.
在進行詳細說明之前，要先行解釋的是，該改質轉爐石，即是指轉爐石經過改質處理後的產物。為了方便說明，先從轉爐石之產生開始說明。首先，從轉爐用鐵水吹煉出一噸鋼時，大約會產出130公斤之冷卻固體物，此冷卻固體物習稱為轉爐石。另外，在吹煉過程中，為了達成去除鐵水中的雜質，通常會加入俗稱生石灰的氧化鈣(CaO)，其反應方程式如下：Before detailed description, it is necessary to explain first that the modified converter stone refers to the product after the converter stone has been modified. For the convenience of explanation, let's start with the production of converter stone. First, when one ton of steel is produced from the converter with molten iron, about 130 kg of cooling solids are produced. This cooling solid is often called converter stone. In addition, in the converting process, in order to achieve the removal of impurities in the molten iron, calcium oxide (CaO) commonly known as quicklime is usually added. The reaction equation is as follows:
2CaO+[Si]+O2 →2CaO．SiO2 2CaO+[Si]+O 2 →2CaO. SiO 2
4CaO+2[P]+5/2O2 →4CaO．P2 O5 4CaO+2[P]+5/2O 2 →4CaO. P 2 O 5
然而，由於鐵水中雜質的含量不易檢測，難以依據反應方程式來提供精確量的氧化鈣，為了確保鐵水中的雜質能確實被去除，所以常加入超量的氧化鈣，這也常會導致加入的氧化鈣沒辦法充分地與鐵水中的雜質作用，進而使轉爐石中殘存游離氧化鈣(Free CaO)。而氧化鈣若是遇到水，將會產生水化反應而形成Ca(OH)2 及CaCO3 ，進而造成體積膨脹、潮解，進而粉化，使得轉爐石的利用性受到限制，因此，需要在轉爐石中加入改質劑來進行改質處理。However, because the content of impurities in the molten iron is not easy to detect, it is difficult to provide an accurate amount of calcium oxide according to the reaction equation. In order to ensure that the impurities in the molten iron can be reliably removed, excessive calcium oxide is often added, which often leads to added oxidation. Calcium cannot fully interact with the impurities in the molten iron, and free calcium oxide (Free CaO) remains in the converter stone. If calcium oxide encounters water, it will produce hydration reaction to form Ca(OH) 2 and CaCO 3 , which will cause volume expansion, deliquescent, and pulverization, which limits the utilization of converter stone. Therefore, it needs to be used in the converter. Adding modifier to the stone to carry out the modification treatment.
具體而言，所述之改質劑是二氧化矽(SiO2 )，及三氧化二鐵(Fe2 O3 )，分別與游離氧化鈣作用之反應方程式如下：Specifically, the modifiers are silicon dioxide (SiO 2 ) and ferric oxide (Fe 2 O 3 ), and the reaction equations for the reaction with free calcium oxide are as follows:
2CaO(free)+SiO2 →2CaO．SiO2 2CaO(free)+SiO 2 →2CaO. SiO 2
2CaO(free)+Fe2 O3 →2CaO．Fe2 O3 2CaO(free)+Fe 2 O 3 → 2CaO. Fe 2 O 3
加入改質劑後，轉爐石中的游離氧化鈣反應成性質相對較為穩定的2CaO．SiO2 ，以及2CaO．Fe2 O3 。由於游離氧化鈣已被轉化消除，也因此大幅降低了會與水分反應而膨脹體積的成分，使得改質後的轉爐石遇水的膨脹率可降至0.5%以下，故可有效消除轉爐石遇水膨脹的問題，使得改質轉爐石成為一種體積安定的可靠工程材料。After adding the modifier, the free calcium oxide in the converter stone reacts to 2CaO with relatively stable properties. SiO 2 , and 2CaO. Fe 2 O 3 . Since the free calcium oxide has been converted and eliminated, the components that will react with moisture and expand in volume are greatly reduced, so that the expansion rate of the modified converter stone in water can be reduced to less than 0.5%, so it can effectively eliminate the converter stone. The problem of water expansion makes the modified converter stone a reliable engineering material with stable volume.
本發明人造建材之該實施例，即是使用上述之改質轉爐石作為主要骨材，配合該樹脂膠結材來製造。其中，該改質轉爐石包括59~63wt%的第一類骨材，及37~41wt%的第二類骨材。其中，該第一類骨材為粒徑小於1毫米的轉爐石粉粒；而該第二類骨材為粒徑介於1毫米至1.7毫米之間的轉爐石顆粒。This embodiment of the artificial building material of the present invention uses the above-mentioned modified converter stone as the main bone material, and is manufactured with the resin cementing material. Among them, the modified converter stone includes 59~63wt% of the first type of bone material and 37~41wt% of the second type of bone. Wherein, the first type of aggregates are converter stone powder particles with a particle size of less than 1 mm; and the second type of aggregates are converter stone particles with a particle size of between 1 mm and 1.7 mm.
本實施例較佳之材質組成如下表1所示：
一般國內人造建材之抗壓強度介於100~130MPa之間，而抗折強度介於10~20MPa之間，比對如上表1所製造出之人造建材，由抗折強度所呈現的數值可知，本實施例在此部分的表現明顯優於其他人造建材，而抗壓強度也位於高標。另一方面，實際對本實施例執行其他相關特性的檢測，結果顯示其吸水率為0.3%，且毒性溶出程序(Toxicity characteristic leaching procedure,TCLP)也顯示無重金屬溶出，各項數值皆優於市售產品，所以具有市場競爭力及創新性。Generally, the compressive strength of domestic artificial building materials is between 100 and 130 MPa, and the flexural strength is between 10 and 20 MPa. Compared with the artificial building materials manufactured in Table 1 above, the value of the flexural strength can be seen. The performance of this embodiment in this part is significantly better than other man-made building materials, and the compressive strength is also at a high standard. On the other hand, the actual test of other related characteristics of this example shows that the water absorption rate is 0.3%, and the Toxicity characteristic leaching procedure (TCLP) also shows no heavy metal leaching, and all the values are better than those on the market. Products, so it has market competitiveness and innovation.
綜上所述，本發明人造建材，藉由改質後的轉爐石作為骨材，配合適當控制大小粒徑之改質轉爐石的重量百分比，成功改善建材的吸水率以及強度，使得轉爐石體積永久安定化，藉此製造出體積穩定、物化性質安定，且確實能符合用於建築之標準的可靠人造建材，故確實能達成本發明之目的。In summary, the artificial building material of the present invention uses the modified converter stone as the aggregate material, and the weight percentage of the modified converter stone with appropriate control of the size and particle size has successfully improved the water absorption and strength of the building material, so that the volume of the converter stone Permanent stabilization is used to produce reliable man-made building materials that are stable in volume, stable in physical and chemical properties, and can indeed meet the standards used in construction, so it can indeed achieve the purpose of the invention.
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention.
