Microcomputer controlled - Martin heat resistance tester
1. Product name: Martin heat resistance tester - microcomputer controlled
2. Product model: ZKMDR-300
3. Main applicable scope and functions:
Manufacturing standard: GB1699-2003 Determination of Martens heat resistance temperature of hard rubber
GB1035-70 Test method for heat resistance (Martens) of plastics
HG/T3847-2008 Determination of Martens heat resistance temperature of hard rubber
It can test the heat resistance temperature of polymer materials such as plastics, nylon, rubber, cable compounds, etc.
Working principle:
Clamp three groups of specimens and adjust them to the specified bending stress value of 5.0MPa, heat at a heating rate of 50±3℃/h, and record the temperature value when the bending deformation displacement of the specimen reaches 6mm.
Advantages description:
1. Displacement is collected by a high-precision digital dial indicator, with higher accuracy and stability.
2. The upper computer software is developed by LABVIEW.
3. Simultaneously display three displacement curves, and any one of them can be closed or displayed at any time.
4. Automatically calculate the counterweight of the weights and determine the position of the loaded weights.
5. After setting the test parameters, the test is fully automatic, and the test data is automatically saved after the test.
6. The test report can be edited and exported to WORD or EXCEL.
7. PID intelligent temperature control system makes the heating rate more stable and reliable.
4. Main technical parameters:
1. Temperature fluctuation: ≤±2℃
2. Constant rate heating rate: 50±3℃/h and 10±2℃/12min
3. Temperature resolution: ±0.1℃
4. Specimen size: strip specimen with length-(120 mm±2mm), width-(15 mm±0.2mm), thickness-(10 mm±0.2)mm; if thickness is greater than 10mm, it can be machined on both sides to 10mm.
5. Test load: 50±0.2kgf/cm2
