Electrostatic copy paper Base paper is a special paper used in electrostatic copiers with a high degree of reproduction fidelity and clarity. It is composed of pulp, filler, resin and electrostatic sensitive agent, its surface coated with a layer of conductive polymer film.

Detection performance
The detection of electrostatic copy paper base paper needs to pay attention to the following main properties:

Thickness and density: The thickness and density of electrostatic copy paper base paper will directly affect its stability and replication effect. The thickness and density can be measured by measuring paper thickness, density and base weight.

Static inductance: The surface of electrostatic copy paper base paper is coated with a conductive polymer film, so the static inductance is required to ensure clarity and detail of the reproduction effect. The measurement of static inductance can be carried out by measuring the electrostatic charge and discharge time of the paper.

Gloss: The base paper of electrostatic copy paper needs to have a certain gloss to enhance the visual effect of the copy effect. The detection of gloss can be done by measuring the reflectivity of the paper surface.

Flatness: The base paper of electrostatic copy paper needs to have a certain flatness to ensure the stability and effect of the copying process. Flatness can be measured by measuring paper surface smoothness, feather height and board convexity and other indicators.

Copying effect: The main feature of electrostatic copy paper base paper is that it has a high degree of copy fidelity and clarity, so the copying effect is an important content of electrostatic copy paper base paper detection. The detection of copy effect can be carried out by measuring the paper copy fidelity, copy clarity and copy color restoration degree and other indicators.

Strength: Electrostatic copy paper base paper needs to have a certain strength to ensure the stability and durability of the paper. The test of strength can be carried out by measuring the tensile strength, tearing strength and compression strength of the paper.

Electrostatic copy paper base paper performance test subjects and methods

Wear resistance: The base paper of electrostatic copy paper needs to have certain wear resistance to ensure the durability of the reproduction effect. The wear resistance can be tested by measuring the wear degree and surface hardness of the paper.

Environmental protection: electrostatic copy paper base paper needs to meet environmental standards, no harmful substances, no pollution to the environment. Environmental protection can be tested by measuring volatile organic compounds, heavy metals, chloride ions, fluorescent brighteners and other indicators.

Scope of application: electrostatic copy paper base paper is usually suitable for electrostatic copiers, so different models of electrostatic copiers need to use suitable base paper. The detection of applicable scope can be carried out by measuring the applicable environment of the paper, applicable copy model and applicable copy material and other indicators.

Reusability: electrostatic copy paper base paper is usually reusable, so it needs to have some reusability. Reusability can be tested by measuring the number of copies of paper and the change in the reproduction effect.

Tension: electrostatic copy paper base paper in the copying process needs to be pulled through the copier mechanism, so it needs to have a certain tension. The tensile force can be measured by measuring the tensile force and tearing strength of the paper in the process of replication.

The above performance indicators are the key content of the detection of electrostatic copy paper base paper. The detection results are very important to ensure the replication effect and stability. Different use requirements and standards will also affect the detection standards and methods of paper.
