【摘要】 研究了磁化时间和磁感应强度对超细煤水煤浆流变特性的影响和磁化对不同浓度超细煤水煤浆流变特性的影响。结果表明,磁感应强度为675mT、磁化时间为10m in时,磁化可明显改善超细煤水煤浆流变特性。在675mT的磁感应强度下,磁化时间对不同浓度的超细煤水煤浆的流变特性影响较大,磁化高浓度比磁化低浓度超细煤水煤浆的时间短,更有利于流变特性的改善。更多还原

【Abstract】 The effect of magnetizing time and magnetic field intensity on the viscosity of ultra-fine CWM were studied.The results indicate that,with time prolonging,the effect of magnetization on the viscosity of ultra-fine CWM basically trends to lower down at first and then raise up.Under the condition of 675mT magnetic field intensity and 10 minutes magnetizing time,the effect of magnetizing on the ultra-fine CWM compared with the ultra-fine CWM blank sample,the rheological behavior of ultra-fine CWM is improved.The magnetization mechanism is also discussed here.更多还原
