Ang papel ng Daolin ay isang mataas na kalidad na propesyonal na papel sa pagguhit, madalas na ginagamit sa pagguhit, disenyo ng disenyo, paglilimbag at kaligrapiya. It has excellent smoothness and transparency, not easy to decolorization and deformation, can be applied to a variety of painting and printing technology.

Pagganap ng pagtuklas
The detection of Daolin paper needs to pay attention to the following main properties:

Kapal at densidad: The thickness and density of Daolin paper will directly affect its stability and use effect. Ang kapal at density ay maaaring masukat sa pamamagitan ng pagsukat ng kapal ng papel, density at base timbang.

Paper strength: Daolin paper needs to have a certain strength to ensure its stability and durability. Ang pagsubok ng lakas ay maaaring isagawa sa pamamagitan ng pagsukat ng lakas ng paghatak, tear strength, folding resistance and other indicators.

Smoothness: 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.

Transparency: 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.

Kulay: 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.

Pagganap ng pagsubok at paraan ng pagsubok ng Daolin paper

Kakayahang umangkop: 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.

Water resistance: 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.

Pangangalaga sa kapaligiran: Daolin paper needs to meet environmental protection standards, does not contain harmful substances, walang polusyon sa kapaligiran. Ang proteksyon sa kapaligiran ay maaaring masuri sa pamamagitan ng pagsukat ng mga volatile organic compounds, mga mabibigat na metal, mga ions ng klorido, floresan brighteners at iba pang mga tagapagpahiwatig.

Saklaw ng aplikasyon: 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.
