二元体系油煤浆常温常压流变特性的研究

配制油煤浆的溶剂为一种石油副产品和循环溶剂的掺混体,与传统的循环溶剂差异较大,研究了常温常压条件下各因素对这类油煤浆粘度的影响规律,分析了二元掺混体系溶剂的流变特性、剪切速率、温度以及溶胀对油煤浆粘度的影响规律。试验结果表明:油煤浆的粘度随溶剂粘度的增大而增大,温度对浆体的粘度影响较大,粘度随温度升高而降低,通过对试验数据的数学回归,建立了一定温度范围内粘度随温度变化的定量关系式。 A petrolium by-product different from traditional recycle solvent were chosen for COM preparation.Some influencing factors for viscosity change of COM were studied under normal temperature and atmosphere.Study the influencing law of theological property,shear rate,temperature and swelling of binary system on the COM viscosity. The results show that viscosity of COM increases with increasing of solvent viscosity.Apparent viscosity decreases with temperature increasing,and the relation equation of viscosity-temperature is established by analysis and regression of experimental data
