摘要
主要针对某涂装线在有缺陷时打磨到底材金属层后点补防锈中涂漆出现针孔缺陷进行分析研究,通过5个影响因素的验证分析,得出基材打磨方式、漆膜厚度、流平性、表面张力是影响湿膜针孔的因素,并提出解决湿膜状态下针孔问题的有效措施.
Abstract
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.
