Analysis and Solution of Pinhole Defects in Water-based Paint Wet Film
This article mainly analyzes and studies the pinhole defects in the painting process of a certain painting line after polishing the substrate metal layer with defects.Through experiments on five influencing factors,it is verified and analyzed that the substrate polishing method,paint film thickness,leveling,and surface tension are the factors that affect the pinhole problem in the wet film state.Effective measures are proposed to solve the pinhole problem in the wet film state.
