A variety of test functions, battery diaphragm testing machine a meet!

Conventional mechanical properties detection of various metal, non-metal and other material samples is very common and very important in the industrial production process of a test, it is mainly through the battery diaphragm testing machine to complete, the use of electromechanical integration design, stretching, peeling, tearing, heat sealing and other test functions can meet a!

Puncture resistance is an important mechanical objective to evaluate the function of diaphragm data, which can reflect whether the diaphragm is prone to short circuit during installation. Will blend of active material, carbon black, plasticizer and PVDF evenly coated on the metal foil, made of lithium battery electrode after high temperature vacuum drying, its appearance from the mixture of active substances and carbon black is made up of tiny particles and appears bumpy, so was sandwiched between the positive and negative electrode gap material, need to accept a lot of pressure, Therefore, diaphragm data should have strong puncture resistance function to avoid short circuit caused by positive and negative contact of lithium battery.

　When the battery diaphragm testing machine is used for puncture resistance function experiment, the sample is clamped in the fixed fixture, and the dynamic fixture with puncture needle is configured to move to the sample at the set speed until the puncture sample. The dynamic fixture contains a force value sensor, which can monitor the change of force value in the process of puncture in real time, so as to obtain the puncture force of the sample. In addition, the fixture is equipped with a displacement sensor for the implementation of monitoring the deformation of the sample.

1. Use a sampler to cut 5 samples from the outer surface of the battery estrangement sample to be tested.

2, in the battery diaphragm testing machine control software to set the experimental speed, sample title, number of experiments and other parameters information, the sample is clamped in a special fixture, and the installation of the needle. Click the "Experiment" option to start the experiment. The puncture needle moves to Pierce the sample according to the set experimental speed, and the equipment shows the change of force value in real time. The puncture force value is stated after the test.

3. Repeat sample clamping and click the experiment operation to test the puncture force values of the other 4 samples.
