    • An electrospray coating head system for applying thin coating to a substrate comprising a slot or blade to meter a liquid onto a shaping structure which forces the liquid to have a single continuous and substantially constant radius of curvature around the shaping structure. A voltage applied to the liquid around the shaping structure causes the liquid to produce a series of filaments which are spatially and temporally fixed, the number of filaments being defined by a simple adjustment in the applied voltage. The filaments break up into a uniform mist of charge droplets and are driven to a substrate by electric fields to produce a coating. Also a method for electrospray coating wherein liquid to be coated is dispensed from a metering portion to a lower shaping means where it achieves a single continuous and substantially constant radius of curvature, a voltage is applied to produce a series of filaments of the liquid which are spatially and temporally fixed, and the filaments break up into a uniform mist of charge droplets.
    • 一种用于将薄涂层施加到包括槽或叶片以将液体计量到成形结构上的薄涂层的电喷雾涂覆头系统,所述成形结构迫使液体在成形结构周围具有单一连续且基本恒定的曲率半径。 施加到成形结构周围的液体的电压导致液体产生一系列在空间和时间上固定的长丝,通过简单的施加电压调整来限定长丝的数量。 细丝分裂成电荷液滴的均匀雾,并通过电场驱动到基底上以产生涂层。 还有一种电喷涂法的方法,其中待涂覆的液体从计量部分分配到下部成形装置,其中其实现单个连续且基本上恒定的曲率半径,施加电压以产生一系列液体细丝 在空间和时间上固定,并且细丝分解成均匀的电荷液滴雾。
