Composite modified admixture based on low-quality silica fume and lithium slag as well as preparation method and application of composite modified admixture
The invention discloses a composite modified admixture based on low-quality silica fume and lithium slag. The composite modified admixture comprises the following components in parts by weight: 20-30 parts of low-quality silica fume, 20-30 parts of lithium slag, 0.5-1 part of a composite dispersant, 0.1-0.3 part of a grinding aid and 40-60 parts of water, the composite dispersing agent comprises an electrostatic potential dispersing component, a suspension stabilizing component and water. The low-quality silica fume and the lithium slag are used as main raw materials, the composite dispersing agent and the grinding aid are combined, the slurry-shaped composite admixture is prepared by adopting a wet grinding process, and the problems of poor discharging fluidity, large quality fluctuation and the like caused by high moisture, low fineness and high water content of the powdery lithium slag can be effectively solved; meanwhile, the technical problems of low tank storage utilization rate, easiness in blockage in pipeline conveying, poor stirring dispersity and the like when the silica fume is used as superfine powder are solved, and an effective way can be provided for resource utilization of the low-quality silica fume and the lithium slag.
本发明公开了一种基于低品质硅灰和锂渣的复合改性掺合料，其组成按重量份数计包括：低品质硅灰20～30份，锂渣20～30份，复合分散剂0.5～1份，助磨剂0.1～0.3份，水40～60份；所述复合分散剂包含静电位分散组分、悬浮稳定组分和水。本发明以低品质硅灰和锂渣为主要原料，结合复合分散剂和助磨剂，采用湿磨工艺制备得到浆状复合掺合料，可有效解决粉状锂渣由于水分大、细度低，含水率高导致的下料流动性差、质量波动大等问题，同时解决硅灰作为超细粉体应用时存在的罐储利用率低、管道输送易堵塞、搅拌分散性差等技术难题，可为低品质硅灰和锂渣的资源化利用提供一种有效途径。
