Novel lining material of high-wear-resistance cyclone separator
The invention relates to the technical field of lining materials, and provides a novel high-wear-resistance cyclone separator lining material which has the advantages of good wear resistance, small volume density, high pressure resistance and breaking strength, small linear change rate after burning, good thermal shock stability and the like compared with a traditional high-wear-resistance lining material. According to the performance indexes, the service life of the high-wear-resistance lining material is greatly prolonged, a solid guarantee is provided for stable operation of a cyclone separator, the high-wear-resistance lining material comprises aggregate, and further comprises a binding agent, powder and an additive which are matched, the aggregate is calcium hexaluminate, the binding agent is SECAR71 pure calcium aluminate cement, the powder is activated aluminum oxide powder and calcium hexaluminate powder, and the additive is calcium hexaluminate cement. The additive is an efficient composite additive, water is added, and the weight ratios of the calcium hexaluminate aggregate, the SECAR71 pure calcium aluminate cement, the activated alumina powder and the calcium hexaluminate powder are 61%, 12%, 9% and 11% respectively.
本发明涉及衬里材料技术领域，提出了高耐磨旋风分离器新型衬里材料，其较传统的高耐磨衬里材料具有耐磨性好、体积密度小、耐压和抗折强度高、烧后线变化率小、热震稳定性好等诸多优点，通过上述性能指标大大提高了高耐磨衬里材料的使用寿命，为旋风分离器的平稳运行提供坚实的保障，包括骨料，还包括配合的结合剂、粉料和外加剂，其中，骨料为六铝酸钙，结合剂为SECAR71纯铝酸钙水泥，粉料为活性氧化铝粉及六铝酸钙粉，外加剂采用高效复合外加剂，外加水，并且六铝酸钙骨料、SECAR71纯铝酸钙水泥、活性氧化铝粉和六铝酸钙粉的重量份比为61％、12％、9％和11％。
