DH-IH Sponge Foam Indentation Hardness Testing Machine

เครื่องนี้ใช้สำหรับวัดความแข็งส่วนเว้าของวัสดุยืดหยุ่นที่มีรูพรุน ตัวอย่างโฟมฟองน้ำโพลียูรีเทนสามารถทดสอบได้ตามมาตรฐานแห่งชาติ และสามารถวัดความแข็งของฟองน้ำ โฟม และวัสดุอื่นๆ ได้อย่างแม่นยำ นอกจากนี้ยังสามารถใช้วัดความแข็งของการเยื้องที่ระบุของโฟมที่นั่ง (เช่น พนักพิง เบาะโฟม ฯลฯ) ที่ผลิตขึ้น และวัดความแข็งของการเยื้องของอุปกรณ์เสริมโฟมของเบาะนั่งได้อย่างแม่นยำ

Application
This machine is used to measure the concave hardness of porous elastic materials. The polyurethane sponge foam sample can be tested according to the national standard, and the hardness of the sponge, foam and other materials can be accurately measured. It can also be used to measure the specified indentation hardness of the seat foam (such as the backrest, cushion foam, etc.) that has been produced, and accurately measure the indentation hardness of the foam accessories of the seat.

Principle
Place the sample between the upper and lower platens, and the upper platen compresses the sample of a certain size downward at a predetermined speed to the concavity specified by the A method (B method, C method) required by the national standard. The load cell thereon feeds back the sensed pressure to the controller for processing and displaying, thereby measuring the indentation hardness of materials such as sponges, foams.,etc.

Function and Feature
1. Automatic clearing: After the computer receives the test start command, the system will automatically do zero clearing.
2. Automatic return: After the sample is broken, it will automatically return to the initial position.
3. Automatic shifting: According to the size of the load, different gear positions can be switched to ensure measurement accuracy.
4. Change speed: This machine can change the test speed arbitrarily according to different samples.
5. Indication verification: The system can achieve accurate calibration of force values.
6. Control method: Test methods such as test force, test speed, displacement and strain can be selected according to the test requirements.
7.A multi-purpose machine: equipped with different specifications of the sensor, can achieve a multi-purpose machine.
8. Curve traversal: After the test is completed, the mouse can be used to find the point-by-point force value and deformation data of the test curve and analyze it.
9. Display: Dynamic display of data and curve test process.
10. Results: The test results are accessible and the data curve is analyzed.
11.Limit: with program control and mechanical limit.
12. Overload: Automatically stops when the load exceeds the rated value.
