Select the film test machine from 7 aspects

With the widespread use of films, everyone has been punished. Now it has been widely used in many fields such as food, medicine, and chemical industry.Testing machineTherefore, it has been applied by customers. However, it is really at a loss to choose a test machine suitable for your use. The following isJinan Hengsi Shanda Instrument Co., Ltd.Several options for the majority of users:

1.When performing tensile tests for plastic film and foil materials, if the test volume is large, pneumatic tensile clamps are chosen, and it is inconvenient to operate with manual clamps, and the gauge distance is difficult to control;

2.Film and foil materials need to have a special cutter when making sample strips.

3.When the sample for the tensile test of plastic film and foil materials is in straight strips, the elongation is generally measured by displacement. Some plastic films areGBWhen the standard is made into dumbbells, only contactless measurement devices can be used to measure elongation (such as infrared testing, laser testing, digital imaging, etc.);

4..Plastic films require tensile and peel tests;

5.Metal foils are divided into: copper foil, aluminum foil, gold foil, etc. The deformation is not very large, usually10%-60%The load is small, and the stretching stroke does not need to be too large. Available to choose5.00NTest machines within the range;

6.The test gauge distance (straight strips) of plastic film and foil materials is generally100mm;

7.Plastic film: The elongation is relatively large, some exceed800%The above requires that the stroke should not be too short, and the force value is generally2kNWithin;
