【摘要】 为提高有机涂层钢板的表观装饰性和工艺优化,对涂层表面鲜映性进行了测量评价,并探讨了影响涂层鲜映性的主要因素及其作用规律。研究表明:降低钢板表面粗糙度、减小涂料的粒度和黏度、增加面漆或底漆的厚度和准确控制面漆烘干温度,均可有效提高钢板鲜映性,改善涂层平滑性。更多还原

【Abstract】 To improve the decoration characteristics of organic-coated sheets and optimize the relevant processes,the distinctness of image(DOI) of organic coating was measured and evaluated.The main factors and the principle influencing the DOI of organic-coated sheet were investigated from the aspect of processes.The results showed(1) decreasing the surface roughness of substrates;(2) reducing the particle size and the viscosity of paints;(3) increasing the thickness of the topcoat and the primer;(4) accurately controlling the drying temperature of the topcoat.These measurements can effectively enhance the DOI and improve the coating flatness.更多还原
