The Importance of Thermal Testing
Thermal paper is a basic consumable for calculators. It not only transmits transaction information, but also affects printing quality, shelf life, environmental requirements, etc. Strict and comprehensive testing of thermal paper ensures reliable quality and performance, while providing dual protection for traders and consumers, while complying with environmental and regulatory standards.
Main inspection items for thermal paper
Appearance inspection: Check the surface flatness, damage, stains, and other defects of the thermal paper to ensure printing quality.
Size and specifications: Ensure that the size and specifications of the thermal paper meet the seller's requirements, comply with industry standards, and be compatible with calculators.
Material composition analysis: Analyze the composition of thermal sensitive materials to ensure that they do not contain harmful substances such as heavy metals and fluorescent agents, and evaluate durability and stability.
Physical performance testing: Ensure that thermal paper operates well in various environments, including tensile strength, elongation at break, wear resistance, water resistance, oil resistance, light resistance, and other testing properties.
Printing effect evaluation: In order to verify the accuracy of printing information, the computer will test the printing quality of thermal paper, with a focus on clarity and color reproduction.
Environmental requirements: Check whether thermal paper contains harmful substances such as heavy metals and harmful solvents, evaluate its recyclability and degradability, and minimize its impact on the environment.
Specific requirements for thermal paper testing
Sample manufacturing: Randomly select thermosensitive samples from the production batch to ensure representativeness. The sample must be dried and cleaned to avoid contamination and damage.
Detection method: Adopt scientific, accurate, and reliable detection methods. For example, using a tensile testing machine to test the tensile strength of thermal paper, using a wear testing machine to evaluate its wear resistance, and using a spectrometer to detect harmful substance content.
Testing environment: Ensure that the testing environment meets relevant standards, can control temperature and humidity, and does not affect the results.
Data processing: Conduct statistical analysis on test results to ensure the accuracy and reliability of the data. Classify and evaluate the quality of thermal paper based on the results.
