Thermal base paper is a special heat-sensitive paper that is usually used in electronic equipment such as printers and label printers. It is highly heat sensitive and can be printed by heating it with equipment such as a thermal printer.
Detection performance
Thermal base paper needs to have the following main properties:
Heat sensitivity: The heat sensitivity of thermal base paper is one of its important performance indicators, which determines the color change and image clarity of the paper after heating. The detection of thermal sensitivity can be carried out by measuring the minimum printing capacity, minimum printing temperature and maximum printing speed of the paper.
Printing quality: The printing quality of thermal base paper includes indicators such as image clarity, color reproduction and printing speed. The detection of printing quality can be carried out by checking the printing effect, line clarity, color reproduction and other indicators of printed matter.
Paper strength: Thermal base paper needs to have a certain strength to ensure its stability and durability. The detection of strength can be carried out by measuring the tensile strength, tear strength, folding endurance and other indicators of paper.
Paper thickness and uniformity: The thickness and uniformity of thermal base paper will directly affect the printing effect and quality of printed matter. The detection of thickness and uniformity can be carried out by measuring indicators such as paper thickness, basis weight and thickness difference.
Heat resistance: Heat-sensitive base paper needs to have certain heat resistance to ensure its stability and printing effect during the printing process. The detection of heat resistance can be carried out by measuring the stability and deformation of paper in a high temperature environment.
Moisture resistance: thermal base paper needs to have certain moisture resistance to ensure the durability and use effect of printed matter. The detection of moisture resistance can be carried out by measuring the stability and deformation of paper in a humid environment.
Machinability: Heat-sensitive base paper usually needs to be processed such as cutting, folding, and mounting, so it needs to have a certain degree of machinability. The detection of processability can be carried out by measuring the performance change and loss of paper in different processing processes.
Environmental protection: Thermal base 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: The scope of use of thermal base paper is mainly for printing and label printing on electronic equipment. The detection of the scope of application can be carried out by measuring the indicators such as the applicable environment, applicable equipment and applicable labels of the paper.
Scratch resistance: Thermal base paper needs to have certain scratch resistance to ensure the durability and use effect of printed matter. The detection of scratch resistance can be carried out by measuring the abrasion resistance and friction coefficient of the paper surface.
The above performance indicators are the key content of thermal base paper detection, and different use requirements and standards will also affect the detection standards and methods of paper.
