LOW-TEMPERATURE BRITTLENESS IMPACT TESTER FOR RUBBER

-
图片
  Features and uses: The low-temperature brittleness impact tester is the highest temperature when the sample is damaged by the impact under the specified conditions, that is, the brittleness temperature, and the performance of the plastic and other elastic materials under low temperature conditions can be comparatively identified. The brittle temperature and low temperature properties of vulcanized rubbers of different rubber materials or different formulations can be determined. 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 GB1682 national standard, and the technical indicators meet the requirements of HG 2-162-1965 plastic low temperature impact compression test method and GB5470-2008 plastic impact embrittlement temperature test method. Technical parameters 1. Temperature control range: room temperature ~ -70 °C (room temperature ≤ 25 ...
