摘　　要：通过进行不同组别的单一变量对照实验来研究不同p H下打浆对装饰原纸遮盖性能与原纸和浸胶压板亮度的影响。实验结果表明:在不影响装饰原纸成纸p H的前提下,在比较高的p H条件下进行磨浆处理的漂白阔叶木浆纤维分丝帚化度与扭结度都较好,与成品钛白粉等无机物填料的结合度上升。综合来看有利于钛白粉等填料在纤维上的附着。The influence of pulp beating on the covering performance of decorative base paper and the brightness of base paper and dip laminate under different pH control was studied through a single variable control experiment of different groups.The experimental results show that under the premise of not affecting the pH of decorative base paper,the bleached hardwood pulp fiber with high pH control has good fiber splitting broom degree and kink degree,and the binding degree with the finished titanium dioxide and other inorganic fillers increases.On the whole,it is beneficial to the adhesion of titanium dioxide and other fillers on the fiber.
