Overview
ZB-L300 vertical computerized tensile instrument is a professional testing instrument under the ZHIBANG brand, which is specially used for the measurement of paper, Cardboard, Plastic film and Miscellaneous Non-metallic materials tensile strength, fracture length, elongation, tensile energy absorption, 180 degree Peel Strength, heat sealing strength and other physical properties. The instrument adopts a vertical single column structure, the chuck spacing is adjustable, the tensile time and load tension are displayed in real time during the test process, and the parameters and tensile curve are automatically displayed and recorded after the sample is broken. The data of a set of samples can be statistically analyzed, and the average value, standard deviation and coefficient of variation can be directly calculated and output.
Features
1. Adopt imported motors for low noise and accurate control.
2. Equipped with large-screen color touch screen, Chinese menu operation, real-time display of stretching time, load tension and tensile curve.
Measurement range of 0-30N, accuracy up to 0.01N, resolution 0.01N, professional for paper measurement.
4. After the test, the measurement results and statistical reports (including average value, standard deviation, coefficient of variation) can be directly displayed and printed.
5. Flexible setting of tensile speed, specimen test length and width.
6. Degree of automation is high, using single-chip microcomputer for information sensing, data processing and action control, with automatic reset, data memory and overload protection functions.
7. It is equipped with a standard RS232 serial interface, allowing for data communication with the host computer.
8. Measurement range is wide, can be converted by configuring different dynamometers, suitable for tensile testing of various materials.
9, multi-functional, flexible configuration, mainly for paper measurement, can also be applied to Miscellaneous materials by changing the configuration.
Principle
The instrument is driven by a motor to stretch the sample clamped between the upper and lower collets at a set speed. During the stretching process, the force value Sensor monitors the tension of the sample in real time, and the displacement Sensor records the elongation change of the sample. The single-chip microcomputer system collects and processes these data, calculates and displays parameters such as tension resistance and elongation in real time. When the sample breaks, the system records various data at the moment of fracture, and can draw tensile curves as needed. After completing a set of tests, the system can perform statistical analysis on the data of multiple measurements.
Applications
Paper tensile performance test, Cardboard tensile performance test, Plastic film tensile performance test, Aluminum foil and Aluminum plastic tape tensile and Peel Strength test, Food Encasement bag heat sealing strength test, Sanitary napkin gluing and edge sealing strength test, Pressure sensitive adhesive Peel Strength test, Synthetic fiber filament breaking strength test, zipper light slip test
Standards
ISO 1924 "Determination of tensile strength of paper and Cardboard", GB/T 12914 "Determination of tensile strength of paper and Cardboard", GB 8808-1988 "Test method for disbonding of soft composite plastics", YY/T 0148-2006 "General requirements for medical tape", GB 13022-91 "Test method for tensile performance of plastics and films"
Steps
1. Turn on the power supply (AC220V +/- 10%, 50Hz) and start the instrument.
2. Set test parameters, such as sample size, tensile speed, etc., through the Chinese menu of the touch screen.
3. Install the sample between the upper and lower chucks to ensure that the clamping is firm.
4. Start the test, the instrument automatically stretches the sample at the set speed, and displays the data and Linear dispersion in real time.
5. After the sample breaks, the instrument automatically stops and records and displays the test results.
6. After the test of a group of samples is completed, the statistical report (average value, standard deviation, coefficient of variation) of the group of data can be viewed and printed by pressing the button.
7. After the test, turn off the power.
Notice
The instrument should be placed on a stable workbench to avoid vibration.
* Power supply voltage must meet the requirements of AC220V +/- 10%, 50Hz.
According to the sample type and standard requirements, set the sample size, chuck width and tensile speed correctly.
When clamping the sample, ensure that it is centered and firmly aligned to prevent slippage or premature breakage during the test.
* Instrument range is 0-100N, do not overload to avoid damage to the Sensor.
* Regularly calibrate and maintain instruments to ensure Measurement accuracy.
Before moving or cleaning the instrument, be sure to disconnect the power supply.
Non-professionals should not disassemble the internal components of the instrument.
