采用HAAKE旋转粘度计研究了推进剂药浆的流变特性。结果表明:药浆在很低剪切速率下呈牛顿性;在一定剪切速率范围内为假塑性;药浆存在流动畸变。文中还介绍了药浆粘度、剪切速率指数、屈服值、触变性及时间、温度的影响规律。
The HAAKE rotational viscometer was used to study the rheological properties of propellant slurry. The results show that the slurry is Newtonian at very low shear rate, pseudoplastic at a certain shear rate, and the flow distortion of the slurry. The paper also introduced the influence of viscosity, shear rate index, yield value, thixotropy and time and temperature of the slurry.
