| Abstract: | Through a comprehensive assessment of aging performance of multicolor section barl,this essay concludes that both different painting technology which include coextrusion,laminating,painting outfitting and polishing and different color systems can exert great influence on ageing performance.Polishing coloring and PVC/PVC coextrusion multicolor section bar has lower wetherability.Adhesive power,peeling strength,chromatic aberration,impact strength retention rate and other indicators can be more comprehensive characterization of color profiles of weathering resistance. |
