Siansonic Focusmist Ultrasonic Nozzle The ultrasonic mist nozzle is an ultrasonic spray nozzle with a small spray width and low flow rate. The nozzle is based on ultrasonic atomization technology. It has a special air flow channel design to uniformly distribute the carrier gas, so that the liquid mist atomized by ultrasonic power is sprayed in a focused shape, thereby reducing the spray area of the ultrasonic spray nozzle. Due to the small spray width of the FocusMist ultrasonic spray nozzle, it is mainly suitable for various applications on small and medium coating area. It is complementary to Siansonic WideMist ultrasonic nozzle and can be applied to almost all substrates with different sizes. One of typical applications of FocusMist ultrasonic nozzle is membrane electrode coatings for proton exchange membrane fuel cell. The catalyst (such as a platinum carbon catalyst) suspension is atomized and sprayed onto a proton exchange membrane to form a uniform catal...
