摘要
选用3种镀镍溶液对丝网印版膜进行表面处理,利用扫描电子显微镜(SEM)、原子力显微镜(AFM)以及Taber耐磨试验机考察处理后膜的表面形貌以及耐磨性能。结果表明:镀镍处理改变了膜的表面形貌,提高了其耐磨性,其中双组分商业镀镍溶液对耐磨性的增强效果最好。基于此配方,进一步考察了镀液温度对于膜耐磨性的影响。结果表明:耐磨性随着镀液温度的升高而增强,并且在40℃下处理的膜的耐磨性最好,与原膜相比,其耐磨性提高了36.6%。
Screen printing is a versatile printing technique that can be used to print images on a wide variety of substrates using a plate which is of great significance to have its service life.The plate consists of a screen (supporting the photosensitive film),a screen frame (fixing the screen) and a UV-curing photosensitive film (forming a printing pattern).The screen printing plate film,including silk screen and photosensitive film,is easy to wear out due to the direct contact with squeegee and ink during the printing.Therefore,it is significant to improve the abrasion resistance of screen printing plate film by simple method.Here,screen printing plate film was treated with three different components of nickel plating solutions.Surface morphology and abrasion resistance of the treated films were investigated by methods of scanning electron microscope (SEM),atomic force microscope (AFM) and Taber abrasion testing machine.The results show that the surface morphology of the treated films has obvious changes,and the roughness and abrasion resistance are improved.The film with optimum abrasion resistance is treated with a twocomponent commercial nickel plating solution,which is attributed to the existence of hemispherical particle on the surface of films.Moreover,the effect of plating temperature on abrasion resistance of film is investigated,which indicating that the abrasion resistance of film increases with temperature.And the film treated at 40 ℃ has the best abrasion resistance,which increases by 36.6% compared with original film.
