To purchase GB/T21302-2007 battery film puncture strength tester to master these contents

When purchasing GB/T21302-2007 battery film puncture strength tester, you must master these contents.
The battery film puncture strength tester adopts an automatic clamping device to complete the test automatically, with accurate and stable test data and good repeatability
.

It is suitable for measuring the puncture resistance of battery separators, films, composite films for packaging, bags and other sheets against being penetrated by a puncture needle (represented by puncture resistance, puncture resistance strength or puncture elongation) Working mode: puncture resistance: puncture needle The Z force required to penetrate the pattern vertically
.

Puncture resistance: Test the puncture resistance of unit thickness
.

Puncture elongation: After the puncture needle touches the sample, the starting point is when the force value reaches the pre-pressure, and the position distance of the puncture needle when the sample penetrates
.

Test method: Put a test piece with a diameter of 100mm on the fixture, press the test button to automatically clamp the sample, and then use a steel needle with a diameter of 1.
0mm and a spherical tip radius of 0.
5mm to measure (50±5) mm/ min or (100±10) mm/min to remove the top puncture, and read the maximum load of the steel needle penetrating the test piece
.

The instrument automatically calculates the puncture strength
.

Note: The number of test pieces is more than 5, and the technical average value is taken
.

2.
Good repeatability Using stepper motor control, the probe travel process is accurate and stable, and the measurement results are repeatable
.

3, easy to use, easy to operate LCD Chinese display, friendly man-machine interface operation
.

The automatic clamping device is adopted to complete the test automatically, with the function of statistical processing of test data, output by a micro-printer, and can also be connected to a computer for operation
.

When connected to a computer, in addition to automatically memorizing and storing the results, it can also display and save the burst curve
.

4.
It is convenient for measurement and calibration.
The instrument is equipped with special calibration weights and has a built-in calibration program, which is convenient for measurement and calibration departments (third parties) to calibrate the instrument
