Description

technical field [0001] The invention belongs to the technical field of spraying, in particular to a spraying pressure control system. Background technique [0002] Painting is the main step in coating construction. In order to obtain an ideal coating film, it is necessary to accurately select the coating method according to the properties of the coating, the structure of the workpiece, and the required coating efficiency. The current methods include spraying, electrodeposition coating, automatic deposition coating, dip coating, roller coating and curtain coating, etc. The traditional spraying system is difficult to control the coating flow rate and the spraying efficiency is low. Contents of the invention [0003] The present invention provides a spraying pressure control system to solve the problems of difficult control of paint flow rate and low spraying efficiency in the existing spraying system in the above-mentioned background technology. [0004] The technical prob...
