Product Description

 

Product Description

 

The low temperature embrittlement testing machine is used to test the embrittlement characteristics of vulcanized rubber and plastic materials under low temperature environment. Soak the sample fixed on the test device in the low-temperature medium for 5 minutes, then impact the sample with the impact head at a linear speed of 2±0.2m/s, and finally check whether there are cracks, cracks, small holes and Whether there is overall damage. The two-stage compressor is used for rapid cooling and refrigeration, and the lowest temperature can reach -70°C (if the temperature is lower than -70°C, liquid nitrogen can be connected to the spare heat exchanger interface, and the lowest temperature can reach -120°C ). High temperature controllability, the liquid heat transfer medium in the low temperature tank can activate the stirring motor, so that the temperature uniformity is better. 4 groups of samples can be tested each time, and the automatic rotation positioning fixture performs impact test on each group of samples to check the lowest temperature for brittle failure.
Executive standard:
ASTM-D746: Type A, ASTM-D746: Type B, GB/T15256, GB/T5470 (Type B), ISO 812, ISO 974, JIS C3005, JIS K 6723, JIS K7216A, JIS K7216 (B), ASTM D2137, etc.
Features:
It adopts integrated control with large-size color LCD touch screen, which is easy to operate, integrated control, automatic timing, and real-time display of temperature. Program automatic control.
Using high-precision temperature control module, PID intelligent temperature control.
The box has a test medium discharge port and is equipped with a manual valve. The test medium is conveniently added and removed.
Temperature uniform mixing system, equipped with electric motor and stirring fan, ensures temperature uniformity.
Ethanol (prepared by the customer) is used as the heat conduction medium, and the temperature uniformity is good.
It adopts French Taikang two-stage hermetic compressor, air-cooled. Advanced multi-channel, environmental protection and energy saving (low noise) mechanical compression refrigeration system. R404A and R23 environmentally friendly refrigerants can quickly cool down to -70°C.
