HMX 基浇注 PBX 药浆表观黏度的实验研究
Experimental Study on the Apparent Viscosity of HMX-based Casting PBX Slurry
摘要
Abstract
The apparent viscosities of HMX-based casting PBX slurry under the conditions of different temperature, addition amount of dispersant,and explosive particle gradation were measured with a rotating viscometer.The effects of these factors on apparent viscosity were studied through the flow curve drawing and data fitting method. The results show that with the increase of temperature,the apparent viscosity decreases,while the flow index increases.The rheological characteristics of the slurry are close to the Newton fluid.The addition of lecithin has an impact on the rheological characteristics of the slurry and is helpful to decrease the apparent viscosity,but its addition amount has a best value.Under the same solid content cases in the slurry,the apparent viscosity in the experimental determination range increases with increasing the content of fine particle in the formula.关键词
