介绍了反映涂布原纸主要质量指标,如全幅分布、原纸强度、平滑度、透气度等指标,并着重探讨了这些质量指标对涂布加工性能的影响。从文中可知,原纸全幅分布包括定量、水分和厚度的分布,分布的均一性的影响表现在涂布吸料、干燥和运行方面;原纸强度包括表面强度、抗张强度和撕裂强度,对涂布加工的影响表现在涂布和印刷适性方面;原纸平滑度、透气度和不透明度对涂布纸的影响主要表现在印刷性能。
The main indexes that reflect the coated base paper, such as full width distribution, base paper strength, smoothness and air permeability, are introduced. The influences of these quality indexes on the coating process performance are also discussed. From the text we can see that the full width distribution of the base paper includes the distribution of the quantitative, the moisture and the thickness. The influence of the uniformity of the distribution is on the aspects of coating absorption, drying and running. The base paper strength includes the surface strength, tensile strength and tear strength, The impact of cloth processing in the coating and printing adaptability; base paper smoothness, air permeability and opacity on the coated paper mainly in the printing performance.
