Method for preparing low-aluminum mullite refractory brick from waste electroceramics
The invention discloses a method for preparing a low-aluminum mullite refractory brick from waste electroceramics, and relates to the technical field of comprehensive utilization of solid wastes and refractory materials. The low-aluminum mullite refractory brick is prepared by taking waste electrical porcelain as a raw material, a water glass solution as a binding agent and industrial solid waste aluminum ash and clay as wrapping materials through the processes of weighing and batching, uniformly mixing the materials, wrapping the wrapping materials, drying, mechanically pressing, performing high-temperature heat treatment and the like. According to the invention, based on the characteristics of block shape, granulation, compactness, hardness and high temperature resistance of the waste electroceramics and the current situation of low added value utilization of solid wastes, the wrapping material is introduced to shield low-melting-point components with deteriorated high temperature performance in the colored glaze of the waste electroceramics, so that the refractory brick with stable shape, strong mechanical property and excellent high temperature resistance is prepared. The method disclosed by the invention has the advantages of cheap and easily available raw materials, simple process, high utilization rate of the waste electrical porcelain and the like, and has important significance for realizing batch high-value utilization of the waste electrical porcelain and reducing the consumption of refractory resources.
本发明公开了一种利用废电瓷制备低铝莫来石质耐火砖的方法，涉及固体废弃物综合利用、耐火材料技术领域。本发明以废电瓷为原料，以水玻璃溶液为结合剂，工业固废铝灰和粘土为包裹料，通过称量配料、均匀混料、包裹料包覆、干燥、机压成型、高温热处理等工艺制备低铝莫来石质耐火砖。本发明基于废电瓷块状、可颗粒化、致密有硬度且耐高温的特性和固废低附加值利用的现状，通过引入包裹料来屏蔽废电瓷色釉料中劣化高温性能的低熔点组分，制备得到具有形状稳定，力学性能强和耐高温性能优良的耐火砖。本发明方法具有原料价廉易得、工艺简单、废电瓷利用率高等优点，为实现废电瓷的批量化高值利用及减少耐火资源的消耗具有重要意义。
