Introduction: XCY-7040-type low-temperature brittleness tester is the determination of material under specified conditions by the impact of damage to the sample when the maximum temperature is brittle temperature, plastic and other elastic materials can be used at comparatively low temperature performance appraisal. Can determine the different rubber materials or different formulations of vulcanized rubber brittle temperature and low temperature performance advantages and disadvantages. Therefore, both in scientific research materials and their products quality inspection, production process control and other aspects are indispensable. The instrument is designed according to GB1682 national standards, the technical indicators meet HG 2-162-1965 plastic low temperature impact compression test methods and GB5470-2008 plastic impact embrittlement temperature test methods and other national standards. Technical Parameters: 1, the test temperature and time :: - 70 ℃ -0 ℃ Cooling time is short, no water cooling, more environmentally friendly. 2, impact speed: 2m / s ± 0.2m / s 3, after the temperature, the temperature fluctuations during the test 3min time: <± 0.5 ℃ fluctuation is small, temperature control more accurate. 4, the impact of the center to the lower holder distance: 11 ± 0.5mm 5, Dimensions: 830 * 540 * 1260 6, power: 800W power is smaller, the compressor also has automatic shutdown after reaching the temperature, more environmentally friendly and energy saving. 7, Volume: 3500 ml larger capacity, the test a wider range
