Magnesium phosphate ceramic cement and preparation method and application thereof
The invention provides magnesium phosphate ceramic cement and a preparation method and application thereof, and belongs to the technical field of nuclear waste treatment. According to the invention, dead burned magnesia and potassium dihydrogen phosphate are used as raw materials of the magnesium phosphate ceramic cement so the strength of the magnesium phosphate ceramic cement is substantially enhanced, and the package capacity and the irradiation resistance of the magnesium phosphate ceramic cement are enhanced; borax and fly ash are used as retarders, the fluidity of the magnesium phosphateceramic cement is improved, the early-stage and long-term compressive strength of the magnesium phosphate ceramic cement is improved; meanwhile, aggregate, fine sand and polyethylene fibers are filled to enhance the physical properties of the ceramic cement, and the compactness and the stability of the cement are improved. The magnesium phosphate ceramic cement has the characteristics of adjustable setting and hardening, high early, middle and later strength, high compactness, radiation resistance, leaching resistance, impact resistance and the like, can be used in the treatment aspects in the fields of radioactive mud, silt and the like, and is suitable for quickly curing nuclear wastes under emergency conditions.
本发明提供了一种磷酸镁陶瓷水泥及其制备方法和应用，属于核废料治理技术领域。本发明采用重烧氧化镁和磷酸二氢钾作为磷酸镁陶瓷水泥的原料，能够显著增强磷酸镁陶瓷水泥的强度，同时增强磷酸镁陶瓷水泥的包容量和耐辐照性能；以硼砂和粉煤灰作为缓凝剂，改善磷酸镁陶瓷水泥的流动性，提高磷酸镁陶瓷水泥的早期和长期抗压强度，同时填充骨料、细砂、聚乙烯纤维增强陶瓷水泥的物理性能，提高水泥的致密性和稳定性，本发明提供的磷酸镁陶瓷水泥具有凝结硬化可调节、早中后期强度高、致密性高、耐辐照性、抗浸出性、抗冲击性等特点，可使用在放射性泥浆、泥沙等领域的处理方面，并适用于应急情况下快速固化核废料。
