AA rapid repair lining material
The invention relates to the technical field of repairing materials, and provides an AA material for quickly repairing a lining, which can quickly repair the damaged part of the lining to ensure that the lining meets the requirements and runs stably, can reduce the cost of manpower, machines and materials, shortens the overhaul period, ensures that the repaired lining is not easy to fall off or semi-fall off, and improves the repair efficiency. The wear resistance of the lining is good, the abrasion loss of the repaired lining is small, so that the service life of the lining is guaranteed, the construction time of the material is about 1 h, and the material is suitable for small-area rapid repair and large-area multi-point construction and comprises composite aggregate and further comprises a binding agent, powder and an additive which are matched with one another, the aggregate is multi-particle calcium hexaluminate, the binding agent is SECAR71 pure calcium aluminate cement, the powder is activated alumina powder and alumina fine powder, the additives are an efficient composite additive and an accelerator, the auxiliary material is a water solvent, and the weight ratio of the SECAR71 pure calcium aluminate cement to the activated alumina powder to the alumina fine powder to the accelerator is 24: 18: 8: 1.
本发明涉及修补料技术领域，提出了AA快速修补衬里材料，其能快速修复衬里损坏部位保证其满足要求平稳运行，可减少人工、机具、材料成本，压缩检修工期，修复后的衬里不易出现脱落及半脱落现象，较好的耐磨性保证了修复后衬里的磨损量较小，从而保证衬里使用的周期寿命，并且本材料施工时间约为1h左右，适用于小面积快速修复，同时也适用于大面积多点施工，包括复合骨料，还包括相互配合的结合剂、粉料和外加剂，其中，骨料为多颗粒的六铝酸钙，结合剂为SECAR71纯铝酸钙水泥，粉料为活性氧化铝粉及矾土细粉，外加剂采用高效复合外加剂和速凝剂，辅料为水类溶剂，并且SECAR71纯铝酸钙水泥、活性氧化铝粉、矾土细粉和速凝剂的重量份比为24：18：8：1。
