metakaolin 中文意思是什麼
metakaolin
解釋
變質高嶺土-
Leaching experiments of metakaolin show that the final al extraction rate in a batch reaction is strikingly influnced by the inferior pore struture geometry of the metakaolin pellets
在輕度潤濕狀態下制備的高嶺石團粒，經煅燒后，仍具有發達的粒內大孔結構。 -
By calcining low humidity pelleted kaolin, a kind of metakaolin pellet, inside which the macroporous structure developed ， has been prepared. the structure remarkbly benifits reactant ion transference. so, the variety has high acid leaching reactivity, even coarse as the pellets are, its reaction kinetic is still maintained zero order up to a significant conversion rate
在用鹽酸加熱浸取時，該類球粒內的鋁質組分表現出高酸溶反應活性，不同粒級的該類球粒有相似的浸出率時間曲線，且大部分鋁能被迅速浸出。 -
It can be seen from this study that avoiding a hardened and impervious lump formed in calcination can accelerate al extraction from coarse metakaolin pellets, and a high leaching rate can be reached within a batch process
該研究結果表明，避免高嶺土球粒在煅燒時被「燒死」 ，能使粗粒煅燒高嶺土的酸溶反應易於進行。
