【摘要】 以微粒沉降速度、粒度分布、粘度大小等为指标，利用正交试验法筛选出磷酸铝凝胶剂的最佳处方。结果表明，磷酸铝凝胶剂的沉降容积比可达９３．１％，其粒度均小于１０μｍ，而且沉降速度较小。更多还原

【Abstract】 The best prescription of aluminum phosphate gel was selected by the orthogonal test. taking sedimentation velocity of particle, graininess distribution and viscosity and so forth as indexes. The results indicated that the ratio of sedimentation volumes of aluminum phosphate gel agent could reach 93.1%, the graininess of that is all smaller than 10μm, and the sedimention velocity was low.更多还原
