Problems solved by technology

The difficulty in implementing this technology is to uniformly disperse the gas phase and liquid phase fluids into the colliding microchannels, and adopt the dendritic layer-by-layer technical method to solve this problem, but this design is difficult to process, and the impact area is different The pressure fluctuation at the position will be transmitted to each colliding microchannel, causing uneven distribution of fluid in each channel
