Abstract:	本研究探討焚化底渣水洗後之細粒徑底渣加入天然材料高嶺土混合燒製調濕材料之可行性，主要針對細粒徑底渣與高嶺土之配比、燒結時之溫度與升溫速率等進行實驗。利用燒結體之狀況、強度與吸水率來選擇最適合之條件，進一步探討燒失量、體縮率、視孔隙度與調濕能力，以及各個參數之間之關係，藉此找出最佳製作調濕材料之條件。本研究利用細粒徑底渣與高嶺土作為混合配比之原料，不同的配比搭配900℃~1,100 ℃之燒結溫度，升溫速率固定5 ℃/min，但在450 ℃到750 ℃之間進行1 ℃/min(H1)、5 ℃/min(H5)兩種設定，由以上條件進行燒結實驗，燒結完成後進行吸水率與抗折試驗，在以上條件中測試出細底渣含量越高燒結溫度越低吸水率較好，抗折強度則相反，因此篩選出細底渣含量30 %與50 %、燒製溫度為1,000℃與1,100℃、升溫速率為H1之參數較佳，因此選擇該條件進一步測試吸放濕能力之試驗。經過調濕能力測試後，燒結溫度為1,000 ℃細底渣含量為30 %、50 %與1,100 ℃細底渣含量為50 %之條件均符合調濕材料之標準，並以1,000 ℃細底渣含量為50 %為佳，本研究最佳調濕材料條件為1,000 ℃細底渣含量為50 %。 In this study, we will discuss the feasibility of fine particle MSWI bottom ash which was water-extracted adding the natural materials, kaolin, mixed firing humidity control materials. Experiments focused on two main points. First the ratio of fine particle of bottom ash and kaolin. Second, temperature and the heating rate of sintering. To choose the most suitable condition by using status of sample, strength and water absorption. To go the step further we will discusses the loss on ignition, body shrinkage, apparent porosity and control ability of humidity. We can use the relationship between the various parameters to find the best way to product the humidity control materials, and this will conducive to selling. In this study, as the mixing ratio of raw materials, fine particles of bottom ash and kaolin will use the different ratio for different sintering temperature between 900 ℃ and 1,100 ℃ The heating rate fixed on 5 ℃/ min but between 450℃and 750℃ we will make two settings, 1 ℃/min(H1)、5 ℃/min(H5). Experimenting from the above conditions. Proceeding water absorption and bending test after the sintering. To base on the experiment above we can find that higher quantity of fine bottom ash content and lower sintering temperature will make better water absorption and the bending tests are just on the contrary. Therefore parameters will be better if the 30% and 50 % fine bottom ash content be sifted, making sintering temperature on 1,000℃ and 1,100 ℃ and using heating rate of H1 so we choose the conditions above to test the ability of humidity control. After the humidity control test, we can see that the sintering temperature is 1,000 ℃ and fine bottom ash content of 30%, 50% and 1,100 ℃ fine bottom ash content of 50 % of the conditions are consistent with the standard of humidity material, fine bottom ash content of 50 % and sintering temperature of 1,000 ℃ heating rate of H1 is better.
