W粉、WC粉粒度分布测试方法的探讨

Discussion on the Test Mode of Size Distribution of W and WC Powder

采用OMECLS -POP(Ⅲ)型激光粒度分析仪对各种粒径的W粉、WC粉粒度分布的测试方法进行了探讨 ,对研磨时间、遮光比、折射率和采样时间等因素对粗、中、细颗粒粒度分布测试的影响进行了选择试验 ,测定结果令人满意。

The test mode of using OMEC LS_POP(Ⅲ) particle size analyzer to test all of the particle sizes of W powder and WC powder is discussed, the effect of factors such as milling time, rate of lightproof, refractive index and sampling time on coarse, medium and fine size distributions are selective tested, the results are satisfied.
