Detailed information on the embrittlement machine (compressor, specimen positioning type) GT-7061-NDA:

1、 Product Introduction:

This machine is used to check the brittleness characteristics of plastic shells and vulcanized rubber of wires during low-temperature testing. Fixed in The sample on the experimental device is immersed in a low-temperature medium5Minutes, then use a punch to hit the head2±0.2m/sThe dry speed impact test piece should be checked for cracks, fissures, small holes, and complete separation into fragments at low temperatures.

Adopting a two-stage compressor for rapid cooling and refrigeration, the lowest temperature can reach-70°C (If it needs to be lower than-70°CTemperature, liquid nitrogen can be connected to the backup heat exchanger interface, and the lowest temperature can reach-120°C)The temperature controllability is high, and the liquid heat transfer medium in the low-temperature tank can be stirred by a motor to achieve better temperature uniformity. Testeable every time4Sample group, The automatic rotating positioning fixture conducts impact testing on each group of samples to detect the lowest temperature where brittle failure occurs.
