Pure wood pulp big axis paper is a kind of paper product, with pure natural wood pulp as raw material, through processing and manufacturing. Generally used for high-end printing, book binding, valuable document protection and other fields.

What is pure wood pulp large spindle paper and what properties does it detect?

Main performance
Its main performance includes the following aspects:

Whiteness: The whiteness of pure wood pulp paper is high, so it can ensure the color and brightness of printed text, patterns and pictures.

Flatness: The flatness of pure wood pulp large-axis paper is good and the surface is smooth, which can ensure the printing quality.

Thickness and weight: pure wood pulp large-spindle paper is usually thicker and heavier, which can ensure the feel and texture of the printed matter.

Durability: As the raw material of pure wood pulp large-axis paper is natural wood pulp, its durability is good, which can ensure the long-term preservation and protection of printed matter.

Moisture content: The moisture content of pure wood pulp large-spindle paper also has a certain impact on its quality, too high or too low moisture content may lead to paper quality decline.

Ph: The PH of pure wood pulp large-axis paper is also one of its important performance indicators. Too high or too low PH will affect the long-term preservation and service life of the paper.

Tension and tearing strength: pure wood pulp large-spindle paper needs to have a certain tension and tearing strength to ensure that it is not easy to damage and deformation in the use and processing process.

Paper density and viscosity: Paper density and viscosity are important factors affecting paper quality and printing quality, and need to use relevant testing instruments for detection.

Color difference and color fastness: pure wood pulp large-spindle paper needs to have good color difference and color fastness in the printing process, otherwise it will affect the color effect of the printed matter.

pH value: The pH value of pure wood pulp large-spindle paper is also an important detection index, which needs to ensure that it is within a certain range, in order to avoid the impact on the environment and human health.
