and step four, opening an electromagnetic valve on the coating delivery pipe, starting a liquid pump on the coating delivery pipe, and delivering the coating which is dispersed and refined in the coating dispersion cavity.
Has the advantages that: the jet flow ejected from the nozzle of each jet pipe passes through the cavity part in the dispersion jet flow cavity and then is ejected into the liquid level in the dispersion jet flow cavity, so that continuous splash-impact type jet flow is formed at the liquid level in the dispersion jet flow cavity, and the splash-impact type jet flow can repeatedly impact the emulsion at the liquid level in the dispersion jet flow cavity, thereby realizing the fine dispersion and the finer emulsification effect of the emulsion in the dispersion jet flow cavity.
