道林纸是一种高品质的专业绘图纸, 绘图中经常使用, 设计, 印刷和书法. It has excellent smoothness and transparency, not easy to decolorization and deformation, can be applied to a variety of painting and printing technology.

检测性能
The detection of Daolin paper needs to pay attention to the following main properties:

厚度和密度: The thickness and density of Daolin paper will directly affect its stability and use effect. 通过测量纸张厚度即可测量厚度和密度, 密度和基重.

Paper strength: Daolin paper needs to have a certain strength to ensure its stability and durability. 强度测试可以通过测量拉伸强度来进行, 撕裂强度, folding resistance and other indicators.

光滑度: Daolin paper needs better smoothness to ensure stability and effect during painting and printing. The test of smoothness can be carried out by measuring the paper surface smoothness, feather height and plate crown and other indicators.

透明度: Daolin paper needs a certain degree of transparency to ensure clarity and quality of painting and printing effects. Transparency can be tested by measuring the transmittance and reflectance of the paper.

颜色: Daolin paper needs to have a certain color to ensure the degree of color restoration and quality of painting and printing effects. The detection of color can be carried out by measuring the color difference value and color uniformity of the paper.

道林纸的性能测试及测试方法

灵活性: Daolin paper needs to have a certain amount of flexibility to ensure that it is suitable for use in fields such as painting and printing. Flexibility can be tested by measuring the number of folds and bending of the paper and other indicators.

耐水性: Daolin paper needs to have certain water resistance to ensure its stability and use effect in wet environment. The water resistance test can be carried out by measuring the time the paper is soaked in water and the water absorption rate.

环境保护: Daolin paper needs to meet environmental protection 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.

适用范围: Daolin paper is widely used, and different uses of Daolin paper need to have different performance requirements. The detection of the applicable scope can be carried out by measuring the applicable environment of the paper, the applicable painting technology and the applicable printing process.

Machinability: Daolin paper usually needs to be cut, folded, mounted and other processing, so it needs to have a certain degree of machinability. The machinability can be tested by measuring the performance change and loss of paper in different processing processes.

Aging resistance: Daolin paper needs to have certain aging resistance to ensure its long-term preservation and use effect. The detection of aging resistance can be carried out by measuring the yellow degree of paper, fading degree, anti-ultraviolet ability and other indicators.

The above performance indicators are the key content of Daolin paper testing, different use requirements and standards will also affect the paper testing standards and methods.
