| 摘要: | 隨著全球環保意識抬頭，廢物回收利用成為熱門的研究議題之一，在台灣鑄造產業為本國相當重要的基礎產業，不但生產高品質也是聞名全球，可是在高產率的背後就是高廢棄物的產生，因此本研究就是利用鑄造業製程中所產生的廢鑄造砂，否可以回收利用製作成實際應用於建築、高溫爐等的耐火斷熱材來進行探討。本研究以鑄造業所產生之回收物來製作出耐火斷熱材來進行探討，首先收集耐火斷熱材的原料、製程技術、檢測方法及相關文獻，在取得回收物後進行成分分析，分析後將資料與收集到的文獻進行交叉比對，整理出各理論成分配比和實驗實驗計畫及製作方法，最後樣品製作完成時，測試體密度、抗壓強度、再熱收縮等…數據，並與實際用於建材上的CNS、JIS規格做比較。從文獻回顧與成分判別來看，再製鑄砂的Al2O3含量略高於原生材料，經過本實驗計算與燒成後的失敗結果得出2種最適配比，這兩種配比在燒成後的成品檢測上都可以達到使用標準。在燒成方面則是以升溫速率慢、持溫時間拉長，來解決耐火磚才容易發生的重大缺失，進而提高成功率使耐火磚的品質提升。
With the rise of global environmental awareness, waste recycling has become one of the hot research topics. The foundry industry in Taiwan is a very important basic industry in the country. Not only is it high quality, but it is also known as high waste. Therefore, this study is to use the waste foundry sand produced in the foundry manufacturing process, whether it can be recycled into the fire-resistant thermal insulation material that is actually applied to buildings, high-temperature furnaces, etc. In this study, the fire-resistant heat-dissipating materials were produced by recycling materials produced by the foundry industry. First, the raw materials, process technology, testing methods and related literatures of the fire-resistant heat-dissipating materials were collected. After the recovered materials were analyzed, the components were analyzed and analyzed. Cross-matching the data with the collected documents, sorting out the theoretical distribution ratios and experimental experimental plans and production methods, and finally, when the samples are completed, test the bulk density, compressive strength, reheat shrinkage, etc., and Compare with CNS and JIS specifications actually used in building materials. From the literature review and component discrimination, the Al2O3 content of recast sand is slightly higher than that of the original material. After the calculation of this experiment and the failure result after firing, the two most suitable ratios are obtained. The two ratios are after firing. The standard of use can be reached on the finished product inspection. In the case of firing, the heating rate is slow and the holding time is extended to solve the major defects that are likely to occur in the refractory bricks, thereby improving the success rate and improving the quality of the refractory bricks. |
