Overview
LD-TD-A paper Cardboard bending stiffness tester is a multi-functional smart microcomputer stiffness tester, suitable for measuring the bending stiffness of paper, Cardboard and other non-metallic materials with a thickness of less than 3mm. The test angle of the instrument can be arbitrarily set between 1 ° and 90 °, and the test time can be arbitrarily set within 3s to 30s. It has the function of automatic zero adjustment test. It uses a color Touchscreen as the human-machine interface to display the stiffness and time Linear dispersion in real time. The operation is simple and convenient.
Features
1. The test angle can be arbitrarily set between 1 ° and 90 °, including 7.5 ° and 15 ° stiffness tests;
2. The test time can be set by any number between 3s and 30s.
3. The change of test angle is automatically controlled by the motor, which improves the measurement efficiency and reduces the human influence;
4. Support 6 kinds of bending length tests: 50mm, 25mm, 20mm, 15mm, 10mm, 5mm;
5. With automatic zero adjustment function, no need to manually rely on the sample before testing;
6. With measurement statistics, printing and other functions, Measurement time can be set;
7. Adopt high-tech digital motors and a streamlined and practical transmission structure.
8. The measurement and Control system uses a single-chip microcomputer as the Central Processor, with application software for control, data collection and processing;
9. The test data is displayed by the LCD display window and the test report is printed by the printer, providing a streamlined structure, comprehensive functions, and easy operation.
Principle
The instrument adopts a measurement and Control system with a single-chip microcomputer as the Central Processor, and is equipped with corresponding application software to control, data collection and data processing of the whole machine. Through the motor automatic control of the test angle change, the stiffness and time Linear dispersion are displayed in real time, and the static bending stiffness measurement of paper, Cardboard and other materials is realized.
Applications
Paper, Cardboard, Other Non-metallic Materials
Standards
GB/T 23144、GB22364-2008、ISO 5628、ISO 2493
Steps
1. Set the test angle between 1 ° and 90 °.
2. Set the test time between 3s and 30s.
3. Select the bending length (50mm, 25mm, 20mm, 15mm, 10mm or 5mm).
4. Use the automatic zero adjustment function, no need to manually rely on the sample;
5. Start the test, and the instrument automatically controls the angle change and collects data.
6. Check the stiffness and time Linear dispersion of the LCD window;
7. Use the printer to print the test report.
Notice
• Ensure that the Working Ambient Temperature is 20 +/- 10 ° C and the Humidity is less than 85%;
• Check whether the automatic zeroing function of the instrument is normal before the test;
• Avoid use beyond the Measurement range (15~ 10000mN) or thickness (0-3mm);
Periodically calibrate instruments to ensure indication variability does not exceed 1%;
• Follow the Touchscreen prompts when operating to avoid misoperation;
• Keep the instrument clean to prevent dust from affecting Measurement accuracy.
