| 摘 要： | 通过3种石油磺酸盐对煤粒表面动电电位影响的测定及采用这些分散剂制成水煤浆的黏度测定，分析了水煤浆黏度与煤颗粒表面动电电位的关系。试验结果表明，水煤浆的黏度随煤粒表面动电电位绝对值的升高而降低，另外水煤浆黏度与分散剂的结构有关。

| Abstract: | With the measurement of three sulfonate of petroleum affected to the dynamic potential on the coal particle surface, the measurement of viscosity for the coal water mixture with dispersing agent, the paper analyzed the relationship between the viscosity of coal water mixture and the dynamic potential of the coal particle surface. The test results showed that the viscosity of the coal water mixture would be increased or decreased with the absolute value of the dynamic potential of the coal particle surface. The viscosity of the coal water mixture has a relation to the structure of the dispersing agent. |
