This machine is used to determine the indentation hardness of porous elastic materials. It can measure polyurethane sponge foam specimens for the prescribed test of national standards, and accurately measure the indentation hardness of sponge, foam and other materials. It can also be used to measure the indentation hardness of seat foam (such as backrest, seat cushion foam, etc.) that has been produced, and accurately measure the indentation hardness of each foam part of the seat.
1.Introduction:
This machine is used to determine the indentation hardness of porous elastic materials. It can measure polyurethane sponge foam specimens for the prescribed test of national standards, and accurately measure the indentation hardness of sponge, foam and other materials. It can also be used to measure the indentation hardness of seat foam (such as backrest, seat cushion foam, etc.) that has been produced, and accurately measure the indentation hardness of each foam part of the seat.
2.Principle
Sponge foam compression stress test will be placed on the specimen between the upper and lower platen, the upper platen to the specified speed downward compression of a certain size of the specimen to the national standard requirements of the A method (B method, C method) specified by the concavity, the load element will be sensed pressure feedback to the controller processing and display, so as to measure the indentation hardness of sponge, foam and other materials such as specimens.
3.Features:
1. Automatic zeroing: After the computer receives the test start command, the system automatically clears the zero.
2. Automatic return: After the specimen is broken, it automatically returns to the initial position.
3. Automatic gear change: According to the size of the load, different gears can be switched to ensure the measurement accuracy.
4. Change speed: The machine can change the test speed arbitrarily according to different specimens.
5. Signal value calibration: The system can realize the accurate calibration of force value.
6. Control method: According to the test needs, test force, test speed, displacement, strain and other test methods can be selected.
7. Multi-use: Equipped with different specifications of sensors, it can realize multi-use of one machine.
8. Curve traversal: After the test is completed, the force value and deformation data of the test curve point by point can be found and analyzed with the mouse.
9. Display: Data and curve test process dynamic display.
10. Results: Test results can be accessed and the data curve can be analyzed.
11. Limit: with program control and mechanical limit.
12. Overload: Automatic stop when the load exceeds the rated value.
