YU8164 plastic impact embrittlement temperature measuring instrument
The instrument adopts a low-temperature refrigerator combined with imported full-closed and electronic refrigeration to replace the traditional carbon dioxide dry ice-cooling agent as a cooling means for the cold bath.
The maximum temperature at which the sample is damaged by impact under the specified conditions, that is, the brittleness temperature, can be used to comparatively evaluate the performance of plastics and other elastic materials under low temperature conditions. It can measure the brittleness temperature and low temperature performance of vulcanized rubber of different rubber materials or different formulations. Therefore, it is indispensable in the quality inspection of scientific research materials and their products, and the control of production processes. The instrument is designed according to CB/T5470 and GB1682 national standards. The technical indicators are in accordance with HG 2-162-1965 plastic low temperature impact compression test method and GB5470-2008 (equivalent to ISO974-80) plastic impact embrittlement temperature test method. National standard requirements. In the original design of the instrument, the cold well agitator was added to make the temperature around the container more uniform, the temperature to drop faster, save time and reduce energy consumption.
