    • PURPOSE: To regularly distribute a powder on a substrate, by forming the uniform film like stream of a powder/gas suspension vertically in the vicinity of the substrate to be coated while accelerating the stream of a gas/powder mixture by introducing the stream of auxiliary gas.
      CONSTITUTION: The film like stream of the powder suspended in gas having a length at least equal to the width of a substrate 2 to be coated is formed vertically in the vicinity of said substrate 2 by a conduit 10 and flowed toward the substrate 2 over the entire width thereof. Subsequently, a gas stream is introduced into the above mentioned stream by a perforated pipe 18 to form turbulent flow and a gas/powder mixture is uniformized with the advance toward the substrate 2 while, by the high speed auxiliary gas stream introduced to the side surface of said mixture from an opening 23, the above mentioned mixture is driven to accelerate the motion of the powder toward the substrate 2. By this mechanism, the powder is regularly distributed on the substrate 2.

    • 目的:为了在基材上规则地分配粉末,通过在待涂覆的基材附近垂直地形成均匀的薄膜状物料流,同时通过引入助剂流加速气/粉混合物流 加油站。 构成:通过导管10将悬浮在长度至少等于待涂布的基板2的宽度的基板2的宽度的气体中的粉末状的薄片形成为在基板2的附近通过导管10流过基板2, 其整个宽度。 随后,通过穿孔管18将气流引入上述流中以形成湍流,并且气体/粉末混合物通过向衬底2的前进而均匀化,同时通过引入到侧表面的高速辅助气流 从所述混合物的开口23中驱动上述混合物以加速粉末向衬底2的运动。通过这种机制,粉末有规则地分布在衬底2上。
