Overview
ZB-L30 vertical computerized tensile instrument is a professional testing instrument under the ZHIBANG brand. It is specially used for the measurement of tensile strength, fracture length, elongation, tensile energy absorption, 180 degree Peel Strength and heat sealing strength of Non-metallic materials such as paper, Cardboard, Plastic film, etc. The instrument adopts a vertical single column structure, the chuck spacing is adjustable, and the tensile time and load tension are displayed in real time during the test process. Immediately after the sample is broken, a number of measurement parameters and tensile Linear dispersion can be displayed and printed, and the statistical results of the whole group of samples can be calculated.
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 can display and print tensile curves.
3. Measurement range of 0~ 30N, accuracy up to +/- 1%, resolution 0.01N, professional measurement for paper and other materials.
4. After the test, the statistical report can be directly displayed and printed, including the average value, standard deviation and coefficient of variation.
5. Flexible sample size, test length, width, and tensile speed can be set.
6. Degree of automation, with automatic reset, data memory, overload protection function.
7. Equipped with a standard RS232 interface, it can communicate with the host computer.
8. Measurement range is wide, and different dynamometers can meet the testing needs of various materials.
9, multi-functional, flexible configuration, in addition to paper is also suitable for Miscellaneous material measurement.
Principle
The instrument uses a motor-driven chuck for uniform stretching to apply axial tension to the sample. During the stretching process, the built-in force value Sensor monitors the load tension in real time, and the displacement Sensor records the elongation change. The single-chip microcomputer system collects and processes this information, calculates and displays parameters such as anti-tension and elongation in real time. When the sample breaks, the system records the peak force value and related data, and can calculate a series of derivative indicators such as tensile strength, fracture length, and tensile energy absorption according to the setting formula.
Applications
Paper tensile performance test, Cardboard strength measurement, 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 tape 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/T12914 "Determination of tensile strength of paper and Cardboard", GB8808-1988 "Test method for disbonding of soft composite plastics", YYT0148-2006 "General requirements for medical tapes", GB13022-91 "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. Adjust the distance between the upper and lower chucks to the set value.
4. Hold the sample correctly between the upper and lower chucks.
5. Start the test, the instrument automatically stretches the sample, and the screen displays the tensile curve, time and force value in real time.
6. After the sample breaks, the instrument automatically stops and displays the test results (such as tension resistance, tensile strength, elongation, etc.).
7. After a group of experiments is completed, the statistical report (mean value, standard deviation, coefficient of variation) of the group can be viewed and printed by pressing the button.
8. After the test, the instrument can be automatically reset.
Notice
* The instrument should be placed on a stable bench to ensure a stable test environment.
* Power supply voltage meets the requirements (AC220V +/- 10%, 50HZ).
Depending on the test material, choose the appropriate load gauge configuration and chuck width.
* When clamping the sample, ensure that the sample is centered and straight to prevent deflection from affecting the test accuracy.
When setting the tensile speed, refer to the relevant material testing standards.
During the test, do not touch moving parts or specimens.
The instrument has an overload protection function, but it should still be avoided for use beyond the range.
Regularly calibrate and maintain instruments to ensure measurement accuracy.
When connecting to the host computer through the RS232 interface, please ensure that the communication settings are correct.
