Overview
YN-TDY01 microcomputer bending stiffness tester is a testing instrument for measuring the flexural stiffness of paper, Cardboard, film, plastic, metal sheet and other composite sheet materials. It supports setting the vertical and horizontal directions, tension size, Test speed and bending angle of the sample by evaluating the stiffness and resilience of the flexibility material, and is widely used in the papermaking, Encasement, printing industry and related scientific research institutions and Quality control departments.
Features
1. 7-Inch Touchscreen with Linear dispersion display, supports free switching between Chinese and English bilingual languages;
The test angle can be arbitrarily set between 1 and 92 degrees.
3. The test time can be set by any number between 2 and 50 seconds.
4. With automatic zero adjustment function, there is no need to manually rely on the sample before testing.
5. After the test is completed, return to the starting position at high speed, and the return speed can be arbitrarily set between 1 and 12.
6. The change of test angle is automatically controlled by the motor, which improves the measurement efficiency and reduces the human influence.
7. The test is automatically reset, and the force value and angle value are automatically cleared during the test to improve the test accuracy;
8. With measurement statistics, printing and other functions, it is convenient for users to conduct test operations and view data.
Principle
The working principle of the stiffness tester is based on the measurement of the force or moment required to bend the specimen at one end to a 15-degree angle under specified conditions, expressed in mN. If the specimen is too large or breaks when bent to a 15-degree angle, the bending angle can be adjusted to a 7.5-degree angle for measurement. Multiply the result by 2 to obtain an approximate value and indicate it in the report.
Applications
Paper, Cardboard, Film, Plastic film and sheet bending stiffness test, various color boxes, toothpaste boxes and other Encasement box crease Closer stiffness test, various banknotes bending stiffness test, various paper Cardboard bending stiffness test, various graphite sheets, Optical inspection diaphragm, non-woven fabric, composite sheet material stiffness test, various wires, power cord, metal cable stiffness test
Standards
GB/T 22364、GB/T 2679·3、ISO 2493、ISO 5628
Steps
1. Prepare the sample, the size is 38 * 70mm, and the actual measurement size is adjustable;
2. Set test parameters, including bending angle, test time, return speed, etc.
3. Use the automatic zero adjustment function, no need to manually rely on the sample;
4, start the test, the instrument automatically controls the angle change and measurement;
5. After the test is completed, it will automatically reset, and the force value and angle value will be cleared.
6. View and print the test results for data statistics.
Notice
Make sure the sample size meets the requirements before testing.
• If the specimen is too large or broken, the bending angle can be adjusted to 7.5 degrees, and the result should be multiplied by 2 and noted in the report.
• Avoid human interference when using automatic functions;
• Regularly calibrate instruments to ensure accuracy;
• Pay attention to safety during operation and avoid touching moving parts.
