Multi sample method rubber low-temperature brittleness/brittleness testing machineSpecifications:

1. Temperature range: normal temperature to -70 ℃;

2. Cooling method: Dual compression mechanism cooling, simple operation, precise temperature control, and low subsequent usage cost.

3. Cooling medium: Alcohol

4. The box has a test medium discharge port and is equipped with a manual valve. The experimental medium is easy to add and remove.

5. Impact head radius; 1.6±0.1 mm

6. Impact velocity: 2 ± 0.2m/s

7Adopting French Taikang two-stage fully enclosed compressor, air-cooled. Advanced multi-channel, environmentally friendly and energy-saving (low-noise) mechanical compression refrigeration system. R404A and R23 are environmentally friendly refrigerants that can quickly cool down to -70 ℃.

8Impact method: The clutch method is used. The motor starts to rotate when it is ready, reaches the speed, and the clutch is engaged during the impact, so that the impact head has a constant speed to strike the sample. After one rotation, the clutch is released.
