    • A system for electrodynamic powder coating of conducting and non-conducting substrates using an electrodynamic fluidized bed. The system generally includes a coating applicator means for applying charged particles to the substrate to be coated, and postcharging means for applying to the substrate an additional charge of such polarity as to cause an increase in the electrostatic forces holding the coating particles to the substrate. The system further includes a precharging means for precharging the substrate with a charge of such polarity as to effect more uniform coating of the substrate and a higher rate of coating. Where the substrate to be coated is a continuous web, the system includes a conveying means for conveying the web through the various positions adjacent to the three aforementioned means. The coating applicator means may be an electrodynamic coating apparatus of the electrodynamic fluidized bed type and comprising a fluidized bed means and a charging bed means with a porous wall positioned therebetween, and a recharging means.
    • 使用电动流化床的导电和非导电基材的电动粉末涂覆系统。 该系统通常包括用于将带电粒子施加到待涂覆的基底的涂布器装置,以及用于向衬底施加额外的极性电荷以使保持涂层颗粒到衬底的静电力增加的后充电装置。 该系统还包括一个预充电装置,用于以这样的极性的电荷对基板进行预充电,以便实现基板的更均匀的涂覆和更高的涂层速率。 在要涂覆的基材是连续的卷材的情况下,该系统包括用于将幅材传送通过与上述三种方法相邻的各种位置的输送装置。 涂布施用装置可以是电动态流化床型的电动涂覆装置,并且包括流化床装置和在其间设置有多孔壁的充电床装置和充电装置。
