Overview
IMT MIT Folding tester (model IMT-FOLD01) is used to detect the folding times and folding resistance of paper, and evaluate the folding fatigue resistance of cardboard, Kraft Paper, cardboard, corrugated paper, gray board paper and other papers. The instrument is suitable for paper manufacturers, Cardboard carton manufacturers, mass supervision bureaus and scientific research institutions and other fields.
Features
1. Measurement range: 0~ 99999 times, to meet a variety of testing needs.
The folding angle can be adjusted from 0 ° to 142 °, providing flexible testing conditions.
3. Folding speed adjustable: 10~ 2000cpm, to adapt to different test standards.
4. Spring tension adjustable: 4.91~ 14.72N, accurate control of the test force.
5. High Stability of Folding Collet: The tension change caused by swirling/spinning eccentricity is not more than 0.343N.
6. Folding head width standard: 19 +/- 1mm to ensure test conformity.
7. Accurate crease radius: 0.38 +/- 0.02mm, improving test accuracy.
Good reproducibility: about 10% (when 30 times) and about 8% (when 3000 times).
9. Sample length requirements: ≥ 140mm, compatible with a variety of paper sizes.
10. Stable crease temperature: change ≤ 1 ℃ (after 4 hours) to ensure stable test environment.
11. Fixed chuck distance: 9.5mm, simplifying operation.
12. Folding mouth seam distance optional: 0.25mm, 0.5mm, 0.75mm, 1.00mm, to adapt to different Paper thickness.
13. Clear display: 5-inch LCD display, real-time display of test data.
14. Convenient printout: modular integrated thermal printer for easy data recording.
15. Strong environmental adaptability: Temperature 0~ 35 ℃, Humidity < 85%.
16. Power standard: AC220V, 50Hz, with strong versatility.
Principle
The measuring instrument applies periodic folding force to the paper sample through the folding head to simulate the folding fatigue process in actual use. The folding angle, speed and tension can be adjusted, and the instrument automatically records the number of folding times of the paper under specific conditions to evaluate its folding performance.
Applications
Paper production enterprises, Cardboard box production enterprises, mass supervision bureau, scientific research institutions
Steps
Prepare the sample: ensure that the sample length is ≥ 140mm.
2. Set parameters: adjust the folding angle, speed, tension and seam distance as needed.
3. Install the sample: Fix the sample to the chuck to ensure that the chuck distance is 9.5mm.
4. Start the test: Turn on the instrument, the folding head starts to work, and the test data is displayed in real time.
5. Record the results: After the test is completed, output the data through the thermal printer.
6. Cleaning and maintenance: After the test, turn off the power and clean the instrument.
Notice
• Ensure that the Ambient Temperature is between 0 and 35 ° C and the Humidity is below 85%.
• Power supply voltage is AC220V, 50Hz before use.
The specimen length must be ≥ 140mm to avoid test errors.
The gap distance between the folding mouth should be selected according to the Paper thickness (0.25mm, 0.5mm, 0.75mm or 1.00mm).
• Avoid touching the folding head during testing to prevent injury.
• Regularly calibrate instruments to ensure test accuracy.
• Keep the instrument clean to prevent dust from affecting performance.
