研究了电解质对聚丙烯酸[poly(acrylic acid),PAA]-α-Al2O3-H2O悬浮液流变性能的影响以及PAA-聚氧化乙烯[poly(ethylene oxide),PEO]-α-Al2O3-H2O悬浮液的抗电解质的性能。结果表明:PAA-α-Al2O3-H2O悬浮液的流变性能受NaCl和CaCl2等电解质的影响较大,并且二价盐CaCl2比一价盐NaCl对PAA-α-Al2O3悬浮液分散和稳定性的影响更明显,电解质造成Al2O3颗粒的絮凝,使浆料的稳定性能变差。在电解质浓度相同的条件下,PAA-PEO-α-Al2O3-H2O悬浮液基本不受电解质的影响,浆料始终保持稳定,PAA-PEO-α-Al2O3-H2O悬浮液具有很强的抗电解质能力。 The effects of electrolytes on the rheological properties of poly (acrylic acid), PAA] -α-Al2O3-H2O suspensions and the effects of PAA-poly (ethylene oxide), PEO] -α-Al2O3- Anti-electrolyte properties of liquid. The results show that the rheological properties of PAA-α-Al2O3-H2O suspension are greatly influenced by electrolytes such as NaCl and CaCl2, and the dispersibility and stability of PAA-α-Al2O3 suspension by divalent salt CaCl2 is better than monovalent salt NaCl The impact is more obvious, the electrolyte caused by the flocculation of Al2O3 particles, so that the stability of the slurry worsened. The PAA-PEO-α-Al2O3-H2O suspension was almost unaffected by electrolytes and the slurry remained stable at the same electrolyte concentration. PAA-PEO-α-Al2O3-H2O suspension had strong anti-electrolyte .
