俄罗斯客户来我司考察塑料低温脆化试验机

This machine is designed for testing samples made of vulcanized rubber. A sample is fixedto a device and then soaked in a medium at a constant low temperature for 5 minutes .The sample is impacted by 
thedart at a linear speed of 2±0.2m/s at a lowest temperature of no occurrence of brittle failure. The sample is thenchecked for cracks ,small holes and fragments.With the two-segmentcompressor, this machine can reduce temperature rapidly. The lowest tempera
-trueis up to -70°C.The temperature is highly controllable, so you no need to add refrigerants 
such as dryice ,liquid nitrogen ,etc. The liquid heat transfer medium in the low temperature tank can be stirred by the stirring motor so as to obtain uniform temperature .Totally 20 samples divided 4 sets can be tested each time. Each set of samplescan be tested by rotating the handle
