滑槽法研究高氯酸铵粉体的静电特性
Study on Electrostatic Characteristics of Ammonium Perchlorate Powder Using the Sliding Chute Method
摘要
Abstract
In order to investigate the electrostatic characteristics of ammonium perchlorate(AP),an adjustable-humidity test apparatus was employed.The effects of sliding chute length,material of sliding chute,environment humidity,cross-sectional shape,and inner diameter on the electrostatic characteristics of AP powder were investigated.Discrete element method(DEM)simulations were utilized to analyze the electrostatic characteristics under different sliding chute shapes and inner diame-ters.The results showed that the electrostatic accumulation of AP powder increases with the length of the sliding chute,and decrease with increased environmental humidity.The accumulation decreased from 271.5 nC at 35％RH to 99.5 nC at 85％RH.Regarding the sliding chute cross-sectional shapes,the accumulation order was:the trapezoidal chute＞the semi-circular＞triangular chutes.Within the inner diameter range of 3 cm to 9 cm,the electrostatic accumulation increased with the sliding chute inner diameter.DEM simulations indicated that the effective contact area between the powder and the sliding chute var-ied with the cross-sectional shape and inner diameter of the sliding chute.An increase in this effective contact area was associ-ated with greater electrostatic accumulation.关键词
