FAQs of Film thermal shrinkage tester:
Q: How does the Film Thermal Shrinkage Tester work?
A: The tester operates using a high precision electric heater to raise the sample temperature, while a microcomputer controls and records the shrinkage of film specimens as they are heated. Results are displayed digitally and can be exported via USB or an optional printer.
Q: What materials and applications is this tester suitable for?
A: This equipment is specifically designed to test the thermal shrinkage properties of plastic films, membranes, and packaging materials, making it ideal for laboratory and quality control use in manufacturing and research.
Q: When should the calibration be performed?
A: Calibration can be carried out automatically or manually before beginning test runs to guarantee measurement precision and accuracy. Regular calibration is recommended depending on testing frequency and laboratory standards.
Q: Where can this tester be installed?
A: The instrument is intended for benchtop installation in laboratories or quality control rooms, requiring access to standard AC 220V power and a clean, dry air supply with 0.6 MPa pressure.
Q: What is the process for conducting a thermal shrinkage test?
A: To perform a test, a specimen (100 mm 100 mm, up to 3 at once) is mounted and parameters such as temperature (up to 200C), timer, and test speed are set. The device heats the sample, measures shrinkage, and records the results, followed by fast cooling to reset for subsequent tests.
Q: How does the equipment ensure safety during operation?
A: Over-temperature and over-current protection systems automatically intervene if preset safety limits are exceeded, protecting both operators and the instrument during usage.
Q: What are the key benefits of using this tester?
A: It offers automated, highly accurate, and rapid shrinkage testing with convenient data management. Its robust construction, safety protections, and programmable features streamline laboratory workflows and enhance productivity.
