Battery film puncture strength tester Shanghai Chengwei Load sensor: resolution of 0.01 N

Battery thin film puncture strength tester Diaphragm puncture strength tester adopts automatic clamping device, fully automatic completion of the test, the test data is accurate and stable, and the repeatability is good
.

It is suitable for measuring the puncture resistance of battery separators, films, composite films for packaging, bags, etc.
to resist being penetrated by the puncture needle (puncture resistance, puncture strength or puncture elongation indicator) Working mode: Puncture resistance: The maximum force
required when the puncture needle penetrates the pattern vertically.

Puncture Strength: Test the puncture resistance
of the thickness.

Puncture elongation: After the needle touches the specimen, it starts when the force value reaches the pre-pressure and reaches the position distance of
the puncture needle when the specimen penetrates.

Test method: put the specimen with a diameter of 100mm on the fixture, press the test key instrument to automatically clamp the specimen, and then use a steel pin with a diameter of 1.
0mm and a radius of 0.
5mm at the top of the spherical tip to go to the top of the test piece at a speed of (50 x 5) mm / min or (100 mm / min) to prick, read the maximum load
of the steel needle through the test piece.

The instrument automatically calculates the puncture strength
.

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

2.
Good repeatability is controlled by stepper motor, 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 use of automatic clamping device, fully automatic completion of the test, with test data statistical processing function, micro printer output, can also be connected to the computer operation
.

When connected to a computer, in addition to automatically remembering and storing the results, the burst resistance curve can also be displayed and saved
.

4.
It is convenient for measuring and calibrating instruments with special calibration weights and built-in calibration procedures, which is convenient for the metering and calibration departments (third parties) to calibrate
the instrument.

Product use: This machine can be used to test the battery separator material tensile, puncture, tearing and other experiments, for quality control, feed inspection, physical properties test, mechanical research, material development of the basic equipment
.

Application areas: film self-adhesive tape, automotive, ceramics, composite materials, construction, food medical equipment, metal, paper, packaging, rubber, textiles, wood, communications and various special-shaped materials This machine meets the battery separator various standards of tensile puncture, customized different puncture fixtures
according to different standards.
