摘要
利用XLY-Ⅱ型毛细管流变仪研究了剪切速率、剪切应力和温度对透明尼龙熔体表观粘度的影响.在测试温度范围内,透明尼龙熔体的表观粘度随着温度的升高、剪切速率和剪切力的增大而降低;透明尼龙熔体为假塑性流体,其非牛顿指数小于1.
The effects of shear rate, shear stress and temperature on apparent viscosity of transparent nylon were discussed by means of XLY- Ⅱ capillary rheometer. The expermental results show that the apparent viscosity decreases with the increase of shear rate,shear stress and temperature within the range of temperature studied and the value of non-Newtonian index of transparent nylon is less than 1,
