Method for preparing high-strength GRC extrusion plate from graphite tailings
The invention discloses a method for preparing a high-strength GRC extrusion plate from graphite tailings, which relates to the technical field of composite materials, in particular to a method for preparing a composite material, which takes graphite tailings, Portland cement, glass fibers and sodium silicate as main materials, and comprises the following steps: firstly, deeply pretreating the graphite tailings to remove magnetic components and active metal oxides in the graphite tailings and avoid later corrosion of an extrusion plate. By utilizing sodium silicate and adopting a standing aging method, removing the viscosity of the mixed material and the strength of the finished product are improved, the shaping effect of the extrusion plate is improved, and the product form is regular.
本发明公开了一种由石墨尾矿制备高强GRC挤压板的方法，涉及复合材料技术领域，该工艺方法以石墨尾矿、硅酸盐水泥、玻璃纤维和硅酸钠为主要材料，首先对对石墨尾矿进行深入地预处理，去除石墨尾矿中的磁性组分和活泼金属氧化物，避免挤压板出现后期锈蚀；利用硅酸钠并通过静置陈化的方法，提高混料的粘度及成品的强度，提高了挤压板的定型效果，产品形态规整。
