  其中,ρ指的是输送气体密度,ρP指的是粉末颗粒密度,ε指空隙度,λ*Z指的是碰撞压力损失系数,fL为fanning摩擦系数,c指管道内颗粒速度,νε指的是气体实际速度,Ex指实际电场强度。由上式可以看出,粉末喷出动力状态与空气输送密度ρ(流速)、粉末颗粒密度ρP(粒径)、空隙度ε(粉量)电场强度Ex以及粉末带电量q密切相关,而与碰撞力、摩擦力以及涡流曳力等阻力可以忽略不计。粉末喷出过程中,空气输送密度、空隙度、电场强度属于外界因素,因此,金属粉与普通粉的区别就在于粉末颗粒密度(ρP)、带电量(q)的区别。

  AP表示颗粒在流体流动方向上的投影面积,ξ表示曳力系数,与颗粒运动的雷诺系数有关。片状金属粉在喷枪与型材之间飘忽不定,AP值也始终处于变化过程中,当金属粉末粒径较小的时候,阻力相对减弱。

  其次,铝银粉、铜金粉以及云母粉的密度不一致,其中铝银粉密度较小,铜金粉密度较大,由于重力的作用,如果以干混的方式加入涂料中则喷粉过程中容易分离,处于bonding状态的金属粉则能够与底粉保持一致性。

  金属粉末涂料生产包括熔融挤出法、干混法以及bonding技术。熔融挤出法与传统的粉末制备工艺一致,只是在原料中加入了金属颜料,然后高速预分散、熔融挤出、压片破碎、磨粉筛分而制成成品,这种方法工艺虽然简单,金属粉与基粉得到均匀混合,但是生产工艺存在高温基础以及高温剪切,容易造成金属表面氧化、金属干混法是将金属粉加入预先制备好的基粉中,通过高速混合制成成品,这种方法的优点是金属粉末不容易被破坏,喷涂后的金属效果充分发挥,其明显不足是金属粉与基粉的分离现象很明显,尤其在喷涂过程中由于重力、形状、带电量与基粉颗粒不一致,造成型材表面色差、金属效果不一致,同时容易对粉泵、文丘管、喷枪电极针、扁平枪嘴造成磨损。

  4.7回收粉对金属效果的影响

  金属粉施工过程中,回收粉的合理使用至关重要,直接影响到涂层的金属效果,并且关系到生产成本(粉末利用率)。回收粉添加比例不一致,将会引起批次色差、金属粉含量少等质量缺陷,尤其是干混金属粉,颜料在回收系统中易被粉碎,单位重量内颜料比重减少、粒径变小、带电量减弱,加之批次粉末颜料比重可能不一致,涂层金属效果不理想。
