【摘要】 为了降低三元料浆的粘度,提高分散性,研究了不同浓度的KCl、K2SO4、K3SO4溶液对煤油水三元料浆ξ-电位的影响。实验表明,KCl、K2SO4、K3PO4可以降低煤浆的ξ-电位,减小煤浆的表观粘度。高价型电解质使煤浆粘度降低幅度大,煤浆分散效果好。从而为提高煤油水三元料浆的分散性找到了一种方法。更多还原

【Abstract】 In order to decrease viscosity of coal-water-oil slurry and increase its dispersity,the influence of different concentration of KCl、H₂SO₄、K₃PO₄ solution on ξ potential of coal-water-oil slurry was studied.The result shows that electrolyte such as K₂SO₄、K₃PO₄ can decrease the ξ potential and the viscosity of coal-water-oil slurry,high valent electrolyte was better.So it can increase the dispersity of coal-water-oil slurry.更多还原
