【摘要】 针对陶瓷料浆单组分分散剂性能单一，适应性和稳定性差，难以满足不同要求的不足，开展了复合分散剂的配方设计及其对料浆流动性的影响规律研究。结果表明：分散剂的复合设计能够优化单一分散剂的掺量范围并提高分散效果，多聚磷酸钠、萘系减水剂、柠檬酸钠和水玻璃可作为复合分散剂的优选组分。多聚磷酸钠与萘系减水剂、水玻璃组成的三元复合分散剂在掺量为0.8%时使陶瓷料浆的流出时间降至44 s,表现出最佳的分散效果。更多还原

【Abstract】 In view of the shortcomings of single component dispersant of ceramic slurry, poor adaptability and stability, it is difficult to meet different requirements, the formula design of composite dispersant and its effect on slurry fluidity were studied.The results show that the compound design of dispersant can optimize the dosage range of single dispersant and improve the dispersion effect.Sodium polyphosphate, naphthalene water reducer, sodium citrate and water glass can be used as the optimal components of the compound dispersant.The ternary composite dispersant composed of sodium polyphosphates, naphthalene superplasticizer and water glass can reduce the discharge time of ceramic slurry to 44 s when the dosage is 0.8%,which shows the best dispersion effect.更多还原
