It is usually a viscous liquid made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and prepared with organic solvents or water. The stability of the paint refers to an indicator of whether the physical properties and usable performance of the paint during storage are affected when the raw material ratio remains unchanged. In the production process of high-stability paint, in order to make the paint reach the desired color, it is necessary to use a paint color mixer to add color paste to the paint, thereby changing the color of the paint; in the prior art, during the use of the paint color mixer, the color paste in the color paste barrel is pushed out by the discharge push plate.
