文化纸是一种用于书籍印刷的专用纸, 杂志, 报纸和其他文化出版物, as well as making art, 画册, greeting cards and so on. Compared with ordinary paper, cultural paper requires higher smoothness, whiteness, 光泽度, 厚度, strength and stability.

文化纸性能测试

The detection of cultural paper mainly includes the following aspects:

光滑度: The surface of the cultural paper should be very smooth to ensure clarity and detail of the text and images. The test of smoothness can be carried out by measuring the paper surface smoothness, feather height and plate crown and other indicators.

白度: The whiteness of cultural paper needs to meet certain standards to ensure the color restoration and contrast of printed words and images. The detection of whiteness can be carried out by measuring the color and color difference of the light reflected by the paper.

Glossiness: Cultural paper needs a certain glossiness to enhance the visual effect of the print. 光泽度的检测可以通过测量纸张表面的反射率来完成.

厚度和密度: Cultural paper needs to have a certain thickness and density to ensure the stability and durability of the paper. The thickness and density can be measured by measuring the thickness and density of the paper.

力量: Cultural paper needs to be strong enough to withstand the tension and pressure of the printing process. 强度测试可以通过测量拉伸强度来进行, 纸张的撕裂强度和压缩强度.

Oxidation: Cultural paper needs to have a certain durability, not easy to yellow, aging, decay, ETC. The oxidation test can be carried out by measuring the pH value, pH and peroxide index of paper.

文化纸性能测试

Printing performance: Cultural paper needs to have certain printing performance to ensure the printing quality of printed matter. The detection of printing performance can be carried out by measuring the paper’s water absorption, 吸油量, printing clarity, color reduction and resistance to printing pollution.

环境保护: cultural paper needs to meet environmental standards, 不含有害物质, 对环境无污染. 通过测量挥发性有机化合物可以检验环境保护, 重金属, 氯离子, 荧光增白剂及其他指标.

The above performance indicators are the key contents of cultural paper testing. 不同的使用要求和标准也会影响纸张的检测标准和方法.
