    WDL-5L lithium battery diaphragm tensile testing machine Lithium ion battery diaphragm is one of the core key materials, and is a key component that restricts battery safety and cycle life
    .

    The main function of the separator is to separate the positive and negative electrode materials of the battery to prevent short circuit due to contact between the two electrodes, while the electrolyte ions pass through it
    .

    On the premise that the thickness is as thin as possible, it is necessary to ensure a certain physical and mechanical strength, including tensile strength, puncture strength, peel strength,
    etc.

    Product features: 1.
    Adopt high-precision, all-digital speed control system and precision reducer, drive the precision screw pair for testing, realize a wide range of test speed adjustment, low noise and stable operation during the test
    .

    2.
    The universal joint adopts a cross pin structure and has the function of limiting the swing angle.
    On the one hand, it is convenient for sample clamping and ensures the concentricity of the test.
    On the other hand, the influence of irregular samples on the sensor is well eliminated
    .

    3.
    Touch key operation mode, LCD display real-time display
    .

    The display interface can display the test method selection interface, the test parameter selection interface, the test operation and result display interface and the curve display interface, which is convenient and quick
    .

    4.
    It has the functions of digital display of test force, continuously adjustable test speed, automatic shutdown of sample breaking, peak hold and other functions
    .

    5.
    The beam speed can be adjusted up and down when the sample is clamped, and it has protection devices such as overcurrent, overvoltage and overload
    .

    6.
    Equipped with a computer interface as standard, which can be connected to an external computer to realize the control of the test process and the storage and printing of data
    .
