metakaolin meaning in English
变质高岭土
偏高岭土
Examples
- 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
在轻度润湿状态下制备的高岭石团粒，经煅烧后，仍具有发达的粒内大孔结构。 - 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
该研究结果表明，避免高岭土球粒在煅烧时被“烧死” ，能使粗粒煅烧高岭土的酸溶反应易于进行。 - 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
在用盐酸加热浸取时，该类球粒内的铝质组分表现出高酸溶反应活性，不同粒级的该类球粒有相似的浸出率时间曲线，且大部分铝能被迅速浸出。
