摘要
研究了Ｗ／Ｏ型聚丙烯酰胺（ＰＡＭ）胶乳在水中的凉阻性能。探讨了聚合物合子量、聚合物溶液浓度、溶液ｐＨ值、流速等对减阻性能的影响。发现Ｗ／Ｏ型聚丙烯酰胺具有良好的减阻性能，在相同流量下，ＰＡＭ水溶位的流动阻力明显小于清水流动阻力。在一定浓度范围内，随ＰＡＭ浓度增加，减阻性能增加。ＰＡＭ的分子量对流动阻力影响较明显，分子量大者减阻性能较高。当溶液ｐＨ值小于７时，减阻性能显著，当ｐＨ值大于７时对减阻影响较少。在相同浓度下，随流速增加，流动阻力减小。
Drag reduction with W/O polyacrylamide latex(PAM)in water was studied in thispaper. Drag reduction is affected by various factors such as polymer molecularl weight,polymer solution concentration,solvent chelnistry, pipe diameter and flow rate. W/O polya-crylamide latex is found to have good drag reduction properties.In general,drag reductionincreases with increasing flow rate,polymer molecular weight, polymer concentration,PHvalue and viscosity of the solution.
