廢玻璃容器取代水泥矽質原料研究

中文摘要 本計畫順應全球水泥產業發展趨勢,轉型水泥廠為靜脈產業的核心,將國內廢玻璃容器回收處理所遇困境提出有效循環再利用方式。廢玻璃容器經回收處理後,絕大數透明與棕色廢玻璃容器得以有效再利用,但在回收處理廢玻璃容器時,仍面臨部分破碎混雜之雜色玻璃及綠色廢玻璃容器無法有效再利用而衍生堆置問題。由於廢玻璃容器之高SiO2含量之特性,可用於水泥製程替代所需矽質原料使用,降低天然礦物的開發使用。廢玻璃容器作為矽質原料替代,於符合水泥配料率值係數條件下,最大可替代比例可達3%。再利用製備成水泥產品成分與控制組並無太大差異。然而,因廢玻璃容器高Na2O含量特性,再利用後將造成水泥鹼含量升高,進而影響水泥產品抗壓強度性能下降,亦同時降低水泥製程熟料易燒性,製程中易使熟料游離石灰偏高。然而,透過含硫原料配套使用,可使鹼含量些微降低,可有效提升熟料易燒性,並進而改善水泥產品抗壓強度性能。其餘水泥凝結性能與體積穩定性能均與控制組水泥差異不大。本計畫利用111.6公噸廢玻璃容器再生料進行實廠試燒驗證,導入量以0.5%替代比例進行水泥生產作業。實廠試燒結果顯示,再利用之水泥產品於成份上可有效控制於變異範圍內,且卜特蘭水泥產品品質皆可符合CNS 61國家標準,且驗證實驗室可行性評估之結果。經本計畫實驗室試驗分析與實廠試燒驗證之成果,可開創廢玻璃容器另一條穩定回收再利用途徑。

Study on the waste glass bottle replaced the silica raw material in cement ingredient

英文摘要 The increasing amount of waste disposal in Taiwan was getting hard to recycle in past decade. The trend of global cement industry development was getting more waste disposal recycled as the substituted cement raw material and substituted fuel, to overcome the heavy waste disposal problem and to decrease the use of the natural mineral in cement industry. In this study, the waste glass bottle was investigated recycle use in cement raw material replaced the use of silica mineral due to the high SiO2 content. The variation of waste glass bottle chemical component is so low that not to be homogenized when recycle use in cement manufacturing process. The alternative ratios 0%, 1%, 2%, 3% of cement raw material replaced by waste glass bottle were used in this study. The test result of cement chemical component by using waste glass bottle is not difference with control set general cement. However, the alkali content in cement is getting higher when the waste glass bottle reused in cement, result in the lower compressive strength of cement product and burning ability of clinker. The sulfur material used as raw material in this study is used to overcome the high cement alkali content problem. The test result shows the compressive strength is recovered to control set cement when the cement using both waste glass bottle and sulfur raw materials. The other general cement property test results including setting time and autoclave expansion were showed not different between general cement product and the cement by using waste glass bottle.
