The low-temperature brittleness testing machine is used to measure the maximum temperature at which the sample of vulcanized rubber is damaged after being impacted under specified conditions, which is the brittleness temperature. It can compare the performance of non-rigid plastics and other elastic materials under low-temperature conditions. For identification, this instrument can be used to determine the brittleness temperature and low-temperature performance of different rubber materials or vulcanized rubber with different formulas. Therefore, this instrument is indispensable in scientific research, quality inspection of rubber materials and products, and quality control in the production process. This instrument is designed according to the national standard GB/T15256-2014 "Determination of low-temperature brittleness of vulcanized rubber or thermoplastic rubber (multi-sample method)" and meets the technical indicators required by the JTS/T232-2019 "Testing Procedures for Water Transportation Engineering Materials" standard .
This instrument adopts cascade compressor refrigeration technology, utilizes the principle of thermal balance and cyclic stirring method to achieve automatic and uniform cooling of the sample and constant temperature. It is simple, convenient and efficient to operate.
