垃圾焚化飛灰燒製調濕陶瓷之模廠研究
A Pilot Study on the Durability of Humidity Control Ceramic Manufactured from MSWI Fly Ash
摘要
本研究所使用的焚化飛灰原灰及水洗灰的Pb皆超出再利用管理標準，分別為71.08±2.85及9.65±0.03 mg/L，而在研磨過後則是低於偵測極限；Zn於水洗及研磨過後呈現下降的趨勢。顯示原反應灰經過水洗及濕式研磨程序後可做為安全無疑慮的原料使用。 研究結果顯示，實驗室規模試驗出來最佳的調濕陶瓷配比為玻璃(G)：飛灰(F)：高嶺土(K)：坡縷石(P)－6：1：2：1燒結時未通氮氣，吸溼量58.39 g/m2，放溼量75%，為日本調濕規範等級第2級標準；而GFKP-6121有通氮氣吸濕量為15.2 g/m2，放濕率則為100%，吸濕效果明顯不好。之後將前階段吸放濕效果較佳之條件的調濕陶瓷應用在不同環境的模廠中。實驗中模廠調溼室初始溼度根據環境濕度而變化，故未能每天達到第2級標準，但是仍能發揮出如實驗室階段差不多的調濕性能，吸濕量最佳仍有60.83 g/m2，根據日本調濕規範等級分布標準有達到第2級標準50 g/m2。

The Pb of the incineration fly ash and water-washed ash used by our team exceeded the reuse management standard of 71.08±2.85 and 9.65±0.03 mg/L. After grinding, it was below the detection limit. Zn showed a downward trend after washing and grinding. It is shown that the raw reactive ash can be used as a raw material without any doubt after water washing and wet grinding process. According to the research results, the better ratio of humidity-controlling ceramics in laboratory sample is (G)glass: (F)fly ash: (K)kaolin: (P) palygorskite - 6:1:2:1 sintering without nitrogen. The moisture absorption is 58.39 g/m2 and the moisture release is 75%, which is the second-level standard of the Japanese humidity regulation standard. However, GFKP-6121 has a nitrogen gas moisture absorption capacity of 15.2 g/m2 and a moisture release capacity over 100%, which is obviously not good for moisture absorption and desorption. After that, the humidity-controlling ceramics with the proportion of GFKP-6121 (without nitrogen) in the previous stage were applied in mold factories in different environments. In the experiment, the initial humidity of the humidity control room of the mold factory changed according to the ambient humidity, so it failed to reach the second level standard every day. However, the humidity control performance similar to the laboratory stage can still be exerted. The best moisture absorption is still 60.83 g/m2. According to the Japanese humidity regulation standard, the grade distribution standard has reached the second grade standard of 50 g/m2.
