Ceramic active powder based on coal gangue as well as preparation method and application of ceramic active powder
The invention discloses ceramic active powder based on coal gangue, and the ceramic active powder comprises the following chemical components in percentage by weight: greater than or equal to 95 percent of SiO2 + Al2O3, 30-45 percent of Al2O3 and less than or equal to 0.5 percent of Fe2O3. The high-end glass fiber disclosed by the invention is high in silicon and aluminum content, low in mullite content, few in impurities, high in sintering activity, small in ignition loss, low in COD (Chemical Oxygen Demand) and good in performance uniformity, can replace pyrophyllite or imported kaolin, and is applied to preparation of high-end glass fibers. The coal gangue solid waste is used as the raw material, the heat treatment temperature is 850-950 DEG C, the heat treatment time is 5-10 seconds, the raw material source is wide, the energy consumption is low, and the production cost is low. The glass fiber prepared by the method is high and stable in quality, the cost of preparing the glass fiber is low, large-scale industrial production of high-end glass fiber can be realized, and high-value resource utilization of high-alumina coal gangue solid waste is realized.
本发明公开了一种基于煤矸石的陶瓷活性粉末，所述陶瓷活性粉末中化学成分以重量百分比计，SiO2+Al2O3≥95wt％，其中Al2O3含量为30‑45wt％，并且Fe2O3含量≤0.5wt％。本发明硅、铝含量高，莫来石含量低，杂质少，烧结活性大，烧失量小，COD低，性能均一性好，可替代叶蜡石或进口高岭土，应用于高端玻璃纤维的制备中。本发明以煤矸石固体废料为原料，采用850‑950℃热处理温度，5‑10s热处理时间，原料来源广泛，能耗低，生产成本低。本发明制备的玻璃纤维质量高且稳定，并且制备玻璃纤维的成本低，可实现高端玻璃纤维的大规模工业化生产，并且实现了高铝煤矸石固废的高值资源化利用。
