Xerographic paper base stock is a special paper used in xerographic copiers that provides a high degree of reproduction fidelity and clarity. It is composed of pulp, filler, resin and electrostatic sensitive agent, etc., and its surface is coated with a 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 xerographic paper base paper will directly affect its stability and reproduction effect. Detection of thickness and density can be carried out by measuring indicators such as paper thickness, density and basis weight.
Electrostatic sensitivity: The surface of xerographic copy paper base paper is coated with a layer of conductive polymer film, so it needs to have a certain electrostatic sensitivity to ensure the clarity and details of the reproduction effect. The detection of electrostatic sensitivity can be carried out by measuring the electrostatic charge and discharge time of paper and other indicators.
Glossiness: The base paper of electrostatic copy paper needs to have a certain glossiness to enhance the visual effect of the copying effect. The detection of gloss can be carried out by measuring the reflectance of the paper surface.
Flatness: The base paper of electrostatic copy paper needs to have a certain flatness to ensure the stability and effect during the copying process. The detection of flatness can be carried out by measuring the smoothness of the paper surface, the height of hairiness and the convexity of the board.
Replication effect: The main feature of xerographic copy paper base paper is its high reproduction fidelity and clarity, so the reproduction effect is an important content of xerographic copy paper base paper detection. The detection of reproduction effect can be carried out by measuring indicators such as paper reproduction fidelity, reproduction clarity and reproduction color reproduction.
Strength: The base paper of xerographic copy paper needs to have a certain strength to ensure the stability and durability of the paper. The detection of strength can be carried out by measuring the tensile strength, tear strength and compressive strength of paper.
Abrasion resistance: The base paper of xerographic copy paper needs to have a certain degree of abrasion resistance to ensure the durability of the reproduction effect. The detection of abrasion resistance can be carried out by measuring the index of paper abrasion and surface hardness.
Environmental protection: The base paper of electrostatic copy paper needs to meet environmental protection standards, contain no harmful substances, and have no pollution to the environment. The detection of environmental protection can be carried out by measuring indicators such as volatile organic compounds, heavy metals, chloride ions and fluorescent whitening agents of paper.
Scope of application: Xerographic copy paper base paper is usually suitable for xerographic copiers, so different types of xerographic copiers need to use suitable base paper. The detection of the scope of application can be carried out by measuring the applicable environment of the paper, the applicable copying model and the applicable copying material and other indicators.
Reusability : Xerographic paper base paper can usually be reused, so it needs to have a certain degree of reusability. The detection of reusability can be carried out by measuring the number of times the paper is copied and the change of the copy effect.
Tensile force: The base paper of electrostatic copy paper needs to be pulled by the mechanism of the copier during the copying process, so it needs to have a certain tensile force. The detection of tension can be carried out by measuring the tension and tear strength of the paper during the copying process.
The above performance indicators are the key content of the base paper detection of xerographic copy paper. The test results are very important to ensure the copy effect and stability. Different use requirements and standards will also affect the paper test standards and methods.
