The rheological experienments suggested that the viscosity of pcn was less than pp " s and decreased with increasing content of montmorillonite. the effects of silicate layer on rheological behaviors of pcn are important to process performance of pcn
材料的毛細管流變測試表明,復合材料加工流動性隨著蒙脫土含量的增加而得以改善,其粘度要低於純pp的粘度,這對加工成型極有指導意義。The results show that the dynamic elastic modulus, loss modulus and complex viscosity of the nanocomposite are higher than those of pp, while the loss factor is lower, that the complex viscosity of the nanocomposites is more sensitive to temperature, and that the flow activation energy and the crystallization temperature increase respectively by 15 % and 10k as compared with pp, which may contribute to the enhanced interfacial interaction between pp and ommt resulting from the addition of tmpp
結果表明:與純聚丙烯相比,納米復合材料具有較高的動態彈性模量、損耗模量和復合粘度,力學損耗因子則降低,納米復合材料的復合粘度對溫度的敏感性略高於聚丙烯;界面改性劑的加入增強了有機蒙脫土與聚丙烯的界面作用,與聚丙烯相比,納米復合材料的流動活化能提高約15 % ,結晶峰溫度提高10k左右。We also found that the rheological behavior of single layer gmt is isotropic. temperature and pressure method has great affection on the distribution of the fiber. second, we measure the pressure change under different molding rate and use extensional viscosities model and shear force model to analysis the data
研究表明: gmt材料具有很好的充模流動性,流動過程中纖維氈保持一個整體; gmt材料擠壓流動行為表現為各向同性;溫度、壓力制度對纖維的均勻分佈影響很大: 2 )通過測量不同合模速率下壓力變化,採用拉伸粘度模型( extensionalviscositiesmodel )和純剪切流動模型( shearforcemodel )對數據進行分析,導出了描述gmt材料宏觀行為的流變學參數。In the numerical solution algorithm, the method of characteristics, analytic method and galerkin finite element method ( galerkin - fem ) can be chosen to solve the advective equation, diffusion equations, reaction ( source / sink ) equations, propagation equations and pressure poisson equation, respectively. the developed new algorithm has been verified using analytical solution of circular conduit flow in a reynolds number range of 100 < re < 1 000 and experimental data of the laminar flow over a backward - step facing step. the flow properties are well characterized by this three - dimensional numerical model
