Sub-nano silicon spar taking boron mud as raw material and preparation method thereof
The invention discloses sub-nano silicon spar taking boron mud as a raw material and a preparation method thereof, and belongs to the technical field of boron mud solid waste recycling and high-valuedtreatment. The sub-nano silicon spar taking the boron mud as the raw material is prepared by mixing the boron mud, mining waste rock, beneficiation tailings, shale and an additive according to a masspercentage ratio of (10-60%): (0-20%): (0-20%): (10-50%): (5-20%); and carrying out wet ball milling, spray granulation, high-temperature firing and heat treatment to obtain the sub-nano silicon spartaking the boron mud as the raw material, the volume weight of the sub-nano silicon spar is less than or equal to 600kg/m < 3 >, and the compressive strength of the sub-nano silicon spar is more thanor equal to 8MPa. The method is a boron mud integrated value-added utilization method, the comprehensive utilization rate of the boron mud is 100%, the method can consume and utilize barren rocks generated in the mining process and tailings generated in the beneficiation process and other solid wastes at the same time, and a light and high-strength sub-nano silicon spar product can be prepared. Ahigh-performance material with a considerable prospect is provided for prefabricated buildings.
一种以硼泥为原料的亚纳米硅晶石及其制备方法，属于硼泥固废资源化、高值化技术领域。该以硼泥为原料的亚纳米硅晶石按质量百分配比，硼泥：采矿废石：选矿尾矿：页岩：添加剂＝(10～60％)：(0～20％)：(0～20％)：(10～50％)：(5～20％)混料；再进行湿法球磨、喷雾造粒、高温烧制后热处理，得到以硼泥为原料的亚纳米硅晶石，其容重≤600kg/m3，抗压强度≥8MPa。该方法是一种硼泥整体化增值利用方法，该方法的硼泥综合利用率为100％，并且该方法同时可消纳利用采矿过程产生的废石及选矿过程产生的尾矿等其他固废，并可制备出轻质高强的亚纳米硅晶石产品，为装配式建筑提供一种前景可观的高性能材料。
