Overview
JINGHUAYIQI JH - WN-LL (30N) Universal UTM is widely used in the measurement of Tensile Strength, elongation and Tensile Energy Absorption of paper, Cardboard and Miscellaneous Non-metallic materials. The instrument can measure paper tension, Tensile Strength, elongation, fracture length, Tensile Energy Absorption, tensile index, Tensile Energy Absorption index, especially can sense small quantities, and has the ability to measure the corresponding parameters of paper (including wet strength value).
Features
1. The transmission mechanism adopts ball bearings for smooth and accurate transmission; it adopts imported motors for low noise and accurate control.
2. Large-screen LCD display, Chinese menu, real-time display of stretching time, load tension, etc. The software has real-time display of anti-tension Linear dispersion function, and the instrument has strong data display and analysis and management capabilities.
3. Adopt modular integrated printer, easy to install and low failure; thermal printer and dot matrix printer are optional.
4. Measurement range of 0~ 30N, accuracy up to 0.01N, resolution 0.01N, paper-specific.
5. Direct measurement results: After completing a set of tests, it is convenient to directly display measurement results and print statistical reports, including average value, Standard Deviation and Coefficient of Variation.
6. Degree of automation: Instrument design uses professional devices at home and abroad, single-chip microcomputer for information sensing, data processing and action control, with automatic reset, data memory, overload protection and fault self-diagnosis characteristics.
7. Multifunctional, flexible configuration: The instrument is mainly used for paper measurement, and changing the configuration of the instrument can be widely applied to the measurement of other materials.
Principle
The instrument uses a single-chip microcomputer for information sensing, data processing and action control, realizes smooth and accurate stretching operation through ball bearing transmission mechanism and imported motor, monitors and displays parameters such as time and load tension in the stretching process in real time, and uses software to analyze Linear dispersion, and finally outputs the measurement results.
Applications
Paper, Cardboard, Aluminum Foil, Aluminum Plastic Tape, Plastic film, Food bag, Towel, Pressure sensitive adhesive tape, Synthetic fiber filament, Zipper
Standards
GB/T 12914-1991、GB 13022-91、GB/T1040-92、GB2792-81、GB/T 14344-9、GB/T 2191-95、QB/T 2171-95
Steps
1. Prepare the sample and set the sample size according to the national standard.
2. Set the chuck spacing within the range of 20 to 240mm, which can be set digitally.
3. Select the stretching speed within the range of 1.0 to 400.0mm/min, which can be adjusted digitally.
4. Start the instrument, conduct tensile test, and observe the stretching time, load tension and other data on the LCD screen in real time.
5. After the test is completed, the instrument automatically displays the measurement results, including the average value, Standard Deviation and Coefficient of Variation.
6. Use the printer to print the statistical report.
Notice
• Power supply voltage needs to be AC220 +/- 10%, 50Hz, 2A.
• Environmental conditions should be maintained at a temperature of 20~ 40 ° C and a relative humidity < 85%.
• Avoid overload use, the instrument has an overload protection function.
• Regularly check the transmission mechanism and motor to ensure smooth operation.
• Verify before use that the instrument configuration applies to the current measurement material.
