摘要：

为研究斯蒂芬酸铅(LTNR)的静电危险性,对其静电积累量和静电火花感度进行了全面的测试。选用不锈钢、铝、夹布胶木、导电胶皮和虫胶漆牛皮纸5 种滑槽,测试了不同滑槽长度和倾斜角度下LTNR 的下滑时间和静电积累量。计算出LTNR 与5 种滑槽的摩擦系数;研究了LTNR 的静电积累量随滑槽长度和倾斜角度的定量关系,分别拟合为线性方程和二次方程;研究了LTNR 的下滑速度和摩擦力对静电积累量的影响,并进行了二元线性回归,得出预估公式。此外,在不同的电容、电阻和极针间隙装置条件下,测试了LTNR 的静电火花感度。结果发现:测试条件对静电火花感度的测试结果影响较大,静电火花感度E50与极针间隙表现出正线性关系。

Abstract:

To characterize the electrostatic hazards of lead styphnate (LTNR), the static electricity accumulation and electrostatic spark sensitivity are tested. 5 kinds of flumes with different lengths and slanting angles made of stainless steel, aluminum, fabroil, conductive rubber and shellac painted kraft are used to test the flowing time and static electricity accumulation of LTNR. The friction coefficients between LTNR and various flumes are calculated. The quantitative relation between the static electricity accumulation and the length and slanting angle of flume is investigated, and the linear and quadratic equations are obtained. The effects of slip velocity and friction on the static electricity accumulation of LTNR are studied, and the binary linear regression equations are obtained. Furthermore, the electrostatic spark sensitivity of LTNR is tested with various capacitances, resistances and electrode gaps. The result shows that the test condition has an significant effect on electrostatic spark sensitivity which increases with the increase in electrode gap.
